- Figure 1 shows a structural side-view of a first embodiment of the container 100 according to the present invention which in this
- the main body of the dispersing device 10 is the container 100 with a rotationally symmetrical receiving section 1 for receiving the physical agent 2 that is to be spread with the dispersing device 10.
- This receiving section 1 is usually a longitudinal enclosing suitable for receiving considerable amounts of said physical agent 2.
- the container 100 can be made of literally any material sufficiently strong to withstand the destructive force of a small detonation, caused by a weak detonating explosive 6 to be described in detail later.
- the wall of the container 100 needs to be just thick enough to withstand a weak detonation.
- its walls can have a various thickness. The thickness must always be determined in direct relation with the characteristics of the material such as their elasticity.
- the thickness is typically between 0.45 and 0.5 mm.
- a common requirement of the material used for producing the container 100 is for it to be available in relatively large quantities, to be relatively cheap and easy to shape/ produce.
- the container 100 can thus be made of various plastics such as PET (polyethylene terephthalate), High Density
- the container 100 is adapted from a conventional PET bottle such as a beverage bottle, the major advantage being their almost universal availability, and low cost.
- a conventional PET bottle used as a container 100 must be adapted to provide it with a predetermined breaking region for releasably securing said physical agent in the container 100, usually by weakening a portion of the PET bottle.
- the container 100 has a wall which in different applications can be provided with special textures/ grooves thus facilitating a more efficient creation of a so-called "gasdispersive pressure vortex" to be discussed later.
- the surface of the wall itself can play a significant role depending on the physical agent 2 used .
- the receiving section 1 has an exit side 7 through which said physical agent 2 is to be released .
- Said exit side 7 comprises a seal 7a with a predetermined breaking region for releasably securing said physical agent in the container 100.
- the seal 7a can disintegrate/open/ break due to the pressure wave caused by said detonation.
- the predetermined breaking region mentioned could be achieved by providing a container 100 having a thinner material close to or at the exit side 7.
- the material of the container 100 could instead also be weakened by etching, stitching, cutting, scoring or scribing. It is also possible to provide an annular region with reduced wall thickness and with an additional etching, stitching, cutting, scoring or scribing . Likewise or in addition the other portions or regions of the container 100 could be reinforced.
- the physical agent 2 which fills the receiving section 1 described above.
- This physical agent 2 can be, depending on application, a liquid such as water, dense/ viscous/ sticky/ powdered/ granular/ mixed or natural- ground material, mud, sand, snow, ice and many other suitable materials. These materials can further be doped with different chemicals depending on application.
- the physical agent 2 comprises water, fire-extinguishing foam, sand, mud, snow, or other fire-suppressing materials.
- the physical agent 2 comprises biosorbents such as microorganisms or biological agents to break down or remove said contamination, or in case of nuclear contamination treatment, different radioactivity neutralizing particles.
- said physical agent 2 contains non-lethal agents such as tear gas, pepper spray, sticky foam, various irritants, or other incapacitants.
- the physical agent 2 comprises some sort of loose opaque agent.
- pulverization of natural materials such as water, sand, dust, soiled water, gelatins, snow or ice might be effective for these purposes as well.
- the container 100 further comprises a rotationally symmetrical transition zone 5 providing for a gradual transition between the diameter of the exit side 7 and the substantially smaller diameter of the pressure input side 3.
- the transition zone 5 provides for a so called expansion zone for the weak detonating explosive 6 ensuring a uniform application of the pressure on the entire cross-section of the receiving section 1.
- the pressure input side 3 has a substantially smaller diameter than said exit side 7.
- the ratio of the diameter at the pressure input side 3 and the diameter at the exit side 7 is in the range Vi to 1/30.
- the container 100 further comprises a cartridge 9 for receiving a weak detonating explosive 6.
- This cartridge 9 can be an integral part with the container 100 or completely separate.
- the role of this cartridge 9 is to accommodate the weak detonating explosive 6 and provide for a detonation chamber, so that when the weak detonating explosive 6 is activated, the pressure wave created by said detonation is directed towards a cartridge exit 11 of this cartridge 9.
- the cartridge 9 part is made stronger than the receiving section 1 part since the cartridge 9 has to withstand greater pressures when the weak detonating explosive 6 is activated.
- the cartridge can be made from the same material as the container 100 or other suitable materials.
- This cartridge 9 is provided with a weak detonating explosive 6 which can be activated in order to create a pressure wave as a result of its detonation.
- This weak detonating explosive 6 can be various types of explosives, such as black powder, trinitrotoluene, hexogen pulverized in porous thick material or deflagrating gun-powder for example.
- the weak detonating explosive 6 is chosen so that the pressure wave created by the weak detonating explosive 6 when activated is travelling at a speed between 1000 and
- the ratio of the physical agent 2 and the weak detonating explosive 6 is preferably between 1/50 up to 1/500 in certain cases.
- the aforementioned ratio is valid for all embodiments described and presented herein.
- the dispersing device 10 also comprises an interface 8 providing for a transition extending a cross-section of said cartridge exit 11 to a cross section of said container 1. Said cross section of the receiving section 1 is larger than the cross section of the cartridge exit 11.
- the interface 8 is preferably implemented as a sleeve adapting different "calibers" of the cartridge 9 and the pressure input side 3.
- the interface 8 is designed so, that commonly used receptacles can be used as the container 100 thus eliminating the need of producing custom-made containers 100.
- PET soft- drink bottles can be used as a container 100 with an interface 8 designed to accommodate these.
- These PET bottles might need slight adaptations to provide said predetermined breaking region. This could be done be weakening a portion of the PET to ensure rupture upon the detonation of the explosive 6.
- a further advantage of using commonly available receptacles as a container 100 is that these are easily available in large quantities almost anywhere, thus reducing the intervention time in some cases.
- the interface 8 and the cartridge 9 will be formed by one single piece designed so that it can perform all functions of each separate part, i.e. the cartridge 9 is strong enough to withstand the force of the detonation, the interface 8 is shaped so that pressure wave is transformed as needed and the receiving section 1 is suitable for receiving and then releasing sufficient amounts of the physical agent 2.
- the receiving section 1, the interface 8 and the cartridge 9 are separate parts so that each can be replaced/ removed separately. This is preferred for example when the receiving section 1 is delivered ready-to use, i.e. filed with the physical agent 2 , and need only be attached to the rest of the dispersing device 10 to be used. An other case where a modular arrangement is advantageous is when the weak detonating explosive 6 comes readily built in the cartridge 9 part.
- the cartridge 9 is fixed into the pressure input side 3 via the interface 8, by fixation means 13.
- the most basic fixation means 13 as shown on figure 1 is a screw-on cap securing the aforementioned elements together.
- the arrangement of the container 1, the interface 8 and the cartridge 9 as described above provides for a transformation of the pressure wave created by said weak detonating explosive 6 when activated into a pressure wave traveling through said physical agent 2. It is to be emphasized that the pressure wave travels through the physical agent 2 as opposed to prior art dispersing devices, where the physical agent 2 is propelled/ ejected by said pressure wave but said pressure wave does not travel through the physical agent 2.
- the effect of said pressure wave travelling through the physical agent 2 is that the physical agent 2 is pulse-pulverized upon release through said exit side 7. Additionally, the exhaust by-products created by the weak detonating explosive 6 when activated, are fully mixed with the physical agent 2 and are also pulse-pulverized together with it.

Description
Container for receiving a physical agent, an activator, a dispersing device and their use for pulverized spreading of a physical agent
Field of the invention [0001] The present invention relates to a container for receiving a physical agent, an activator for activating said container, a dispersing device for spreading a physical agent, and their use for spreading a physical agent using such a dispersing device.
Background of the invention [0002] A quick, even pulverized spreading of an agent has long been an issue in several fields of activity. Some of these fields are firefighting, explosive prevention, localization and confinement of toxic chemicals or radioactive material, cleaning of oil spreads on water surfaces, heat protection, camouflage or crowd/ terrorist control. A common problem has been that in order to ensure a proper effect and to achieve a sufficiently even coverage, very often a much larger amount of agent has been used .
Obviously this leads to a significant amount of waste of the agent. Even though in many cases the price of the agent is negligible, the time and cost to produce, deliver, prepare for use and distribution of it is significant. Thus the
use of unnecessary agent just to ensure that the entire area is covered with at least some of the agent leads to serious disadvantages. Not only significant amounts of agent are wasted, but in many cases an excess of said agent may cause further damages. [0003] For example if some sort of decontaminant needs to be spread evenly on a large surface, if one uses classical means for said spreading there is a constant danger that either spots are missed, or if this is avoided by an excess of agent, some areas might be overdosed . If used in large amounts even weak chemicals might cause serious damages. Additionally, some decontaminants can be very expensive, so an optimal use is critical.
[0004] A further example is firefighting, where usually a larger amount of agent, i.e. water, foam, etc., is spread in order to ensure that the entire burning surface is covered and no spots are missed . However, the
effectiveness of the water usage can be as low as 3%. A side effect of this is that in many cases, even though the fire is successfully extinguished, the affected property (building, vehicle, etc) is completely soaked and a
significant part of the damage is caused by the fire extinguishing agent itself. It has been reported numerous times that even if a burning building has been relatively quickly extinguished, it had to be demolished since the excess water has weakened the structure of the building making it unsafe. A further danger firefighters have to face is electrocution. It is statistically proven that a very high percentage of all fires are caused by electricity. However, firefighters often can not intervene due to the high risk of electrocution. Often critical time is lost until the area is disconnected from all power sources. [0005] In case of forest fires and such extended areas, the vast surface that needs to be covered with a fire extinguishing agent makes the waste of these agents even more severe. Since very often forest fires occur in remote and/or dry areas the mere task of providing sufficient amount of fire
extinguishing agent, quite often water, is difficult or even impossible. Thus the efficient use of the resources available is essential .
[0006] An other field where a very thin but even coverage is a
requirement is the confinement/ treatment of water pollution such as oil spills.
Confinement and treatment of water contamination usually involves large surfaces of open water which need to be treated fast and thorough. There are two stages of such disaster relief efforts: confinement and treatment. In first step the pollution has to be somehow confined in order to prevent the contamination of further areas. In a second stage, the area affected has to be treated . The even spreading of an agent has to be done for both stages but comes into play essentially in the second stage when some sort of biosorbent has to be spread on the contaminated water surface. An even coverage of the surface with such biosorbents will ensure a proper decontamination of the area allowing a quick recovery of the local ecosystem. However, an
exaggerated use of these biosorbents by excessive coverage can cause even more damage to the ecosystem heavily affecting the quality of water and the natural habitat. Furthermore, the price of these agents and the high amount needed to cover extended surfaces ask for an effective and precise method for spreading said agent that can minimize the amount needed but at the same time ensure that the entire surface is covered .
[0007] In crowd control, a quick but controlled deployment of smoke, tear gas, pepper spray, sticky foam, or other incapacitants is essential. At the same time an overdose, i.e. an inadequate concentration of these agents might cause serious injuries leading to moral and/or legal issues.
[0008] The objective of the present invention is thus to provide a dispersing device and a corresponding method which enable a quick but uniform distribution of a physical agent while at the same time minimizing the amount of agent required without compromising the uniformity of the coverage.
[0009] A further object of the present invention is to provide a
dispersing device that is easy and cheap to produce, with high versatility suitable for spreading a wide range of agents in an effective manner.
[0010] An even further objective is to provide a dispersing device that is easy to use and which is at the same time also reusable to minimize cost and waste.
[0011] A further objective of the present invention is to provide a dispersing device that is scalable and customizable for specific deployment areas.
SUMMARY OF THE INVENTION [0012] The above-identified objects are solved by the present invention by a dispersing device for spreading a physical agent comprising a container according to claim 1 and an activator according to claim 3. Said container comprising : a rotationally symmetrical receiving section for receiving a physical agent having an exit side through which said physical agent is to be released, wherein said exit side comprises a seal with a predetermined breaking region for releasably securing said physical agent in the container and a rotationally symmetrical pressure input side situated at an opposite end of said exit side, the pressure input side having a substantially smaller diameter than said exit side; a rotationally symmetrical transition zone providing for a gradual transition between the diameter of the exit side and the substantially smaller diameter of the pressure input side; a cartridge comprising a weak detonating explosive, said cartridge having a cartridge exit; and an interface providing for a transition extending a cross-section of said cartridge exit to a cross-section of the pressure input side of said receiving section, wherein said cartridge is provided with a fixation means securing said cartridge into the pressure input side via said interface, wherein said receiving section, transition zone and pressure input side form one unitary piece.
[0013] Said activator for activating a weak detonating explosive within the cartridge of the container comprises: an activator body; a connection interface for mechanically/ releasably connecting the activator body with the container; a shock igniter configured to exercise, when actuated, a high pressure on the weak detonating explosive in order to activate it.

DESCRIPTION OF PREFERRED EMBODIMENTS
[0023] The term activation will be used in the context of the present application with the meaning of some sort of action causing a detonation, ignition, etc of an explosive or deflagrating gun powder. Generally speaking, activation will cause said explosive or deflagrating gun powder to detonate/ deflagrate and create a pressure wave as a result of said
detonation/deflagration. The activation can be by an electric detonator, a mechanical detonator, a simple fuse or other known means used in the field to detonate an explosive material such as a shock igniter.
[0024] The term weak detonating explosive is being used in the context of the present application to refer to any type of explosive or deflagrating material that is suitable to create a pressure wave when activated .
[0025] Figure 1 shows a structural side-view of a first embodiment of the container 100 according to the present invention which in this
arrangement is a multi-purpose device, i.e. it could be used with little or no modification for any of the above-enlisted purposes.
[0026] The main body of the dispersing device 10 is the container 100 with a rotationally symmetrical receiving section 1 for receiving the physical agent 2 that is to be spread with the dispersing device 10. This receiving section 1 is usually a longitudinal enclosing suitable for receiving considerable
amounts of said physical agent 2. The container 100 can be made of literally any material sufficiently strong to withstand the destructive force of a small detonation, caused by a weak detonating explosive 6 to be described in detail later. At the same time the wall of the container 100 needs to be just thick enough to withstand a weak detonation. Depending on the material of the container 100, its walls can have a various thickness. The thickness must always be determined in direct relation with the characteristics of the material such as their elasticity. In case of a PET bottle used as a container 100, the thickness is typically between 0.45 and 0.5 mm. [0027] A common requirement of the material used for producing the container 100 is for it to be available in relatively large quantities, to be relatively cheap and easy to shape/ produce. Depending on the size and application of the dispersing device 10, the container 100 can thus be made of various plastics such as PET (polyethylene terephthalate), High Density
Polyethylen (HDPE), Low Density Polyethylene (LDPE), Polyvinyl Chloride (PVC), Polypropylene (PP), Polystyrene (PS), Fluorine Treated HDPE or Post Consumer Resin (PCR). Different lightweight metals or even composite materials may also be used. In certain embodiments of the present invention, the container 100 is adapted from a conventional PET bottle such as a beverage bottle, the major advantage being their almost universal availability, and low cost. Depending on specific embodiment, the bottom part of a conventional PET bottle used as a container 100 must be adapted to provide it with a predetermined breaking region for releasably securing said physical agent in the container 100, usually by weakening a portion of the PET bottle. [0028] The container 100 has a wall which in different applications can be provided with special textures/ grooves thus facilitating a more efficient creation of a so-called "gasdispersive pressure vortex" to be discussed later. The surface of the wall itself can play a significant role depending on the physical agent 2 used . [0029] On one end, the receiving section 1 has an exit side 7 through which said physical agent 2 is to be released . Said exit side 7 comprises a seal 7a with a predetermined breaking region for releasably securing said physical
agent in the container 100. The seal 7a can disintegrate/open/ break due to the pressure wave caused by said detonation.
[0030] The predetermined breaking region mentioned, could be achieved by providing a container 100 having a thinner material close to or at the exit side 7. The material of the container 100 could instead also be weakened by etching, stitching, cutting, scoring or scribing. It is also possible to provide an annular region with reduced wall thickness and with an additional etching, stitching, cutting, scoring or scribing . Likewise or in addition the other portions or regions of the container 100 could be reinforced. [0031] Probably the most important and various aspect of the present invention is the physical agent 2 which fills the receiving section 1 described above. This physical agent 2 can be, depending on application, a liquid such as water, dense/ viscous/ sticky/ powdered/ granular/ mixed or natural- ground material, mud, sand, snow, ice and many other suitable materials. These materials can further be doped with different chemicals depending on application. For fire-fighting applications, the physical agent 2 comprises water, fire-extinguishing foam, sand, mud, snow, or other fire-suppressing materials. For contamination-treatment applications, the physical agent 2 comprises biosorbents such as microorganisms or biological agents to break down or remove said contamination, or in case of nuclear contamination treatment, different radioactivity neutralizing particles. For crowd-control applications said physical agent 2 contains non-lethal agents such as tear gas, pepper spray, sticky foam, various irritants, or other incapacitants. When the dispersing device 10 is used for camouflage purposes, the physical agent 2 comprises some sort of loose opaque agent. Furthermore, pulverization of natural materials such as water, sand, dust, soiled water, gelatins, snow or ice might be effective for these purposes as well.
[0032] The container 100 further comprises a rotationally symmetrical transition zone 5 providing for a gradual transition between the diameter of the exit side 7 and the substantially smaller diameter of the pressure input side 3. The transition zone 5 provides for a so called expansion zone for the
weak detonating explosive 6 ensuring a uniform application of the pressure on the entire cross-section of the receiving section 1.
[0033] The pressure input side 3 has a substantially smaller diameter than said exit side 7. In preferred embodiment the ratio of the diameter at the pressure input side 3 and the diameter at the exit side 7 is in the range Vi to 1/30.
[0034] The gradual transition between the diameter of the exit side 7 and the substantially smaller diameter of the pressure input side 3 extends or stretches via a section which has a length between 1 and 10cm. [0035] As shown in Figure 1, the container 100 further comprises a cartridge 9 for receiving a weak detonating explosive 6.
[0036] This cartridge 9 can be an integral part with the container 100 or completely separate. The role of this cartridge 9 is to accommodate the weak detonating explosive 6 and provide for a detonation chamber, so that when the weak detonating explosive 6 is activated, the pressure wave created by said detonation is directed towards a cartridge exit 11 of this cartridge 9. Usually, the cartridge 9 part is made stronger than the receiving section 1 part since the cartridge 9 has to withstand greater pressures when the weak detonating explosive 6 is activated. The cartridge can be made from the same material as the container 100 or other suitable materials.
[0037] This cartridge 9 is provided with a weak detonating explosive 6 which can be activated in order to create a pressure wave as a result of its detonation. This weak detonating explosive 6 can be various types of explosives, such as black powder, trinitrotoluene, hexogen pulverized in porous thick material or deflagrating gun-powder for example. In the preferred embodiment of the present invention the weak detonating explosive 6 is chosen so that the pressure wave created by the weak detonating explosive 6 when activated is travelling at a speed between 1000 and
3000m/s. [0038] The use of a cartridge 9 to hold the weak detonating explosive 6 makes the recharging, i.e. refitting the dispersing device 10 with a new load
of weak detonating explosive 6 after its use, a lot faster and easier step. This is especially preferred when the dispersing device 10 is to be used repeatedly. Thus instead of replacing the entire dispersing device 10 for a repeated use, one only needs to insert a new cartridge 9 with weak detonating explosive 6 into the interface 8. This step can thus be carried out even by the user itself without any tools or special knowledge.
[0039] According to the preferred embodiment of the present invention, the ratio of the physical agent 2 and the weak detonating explosive 6 is preferably between 1/50 up to 1/500 in certain cases. The aforementioned ratio is valid for all embodiments described and presented herein.
[0040] The dispersing device 10 also comprises an interface 8 providing for a transition extending a cross-section of said cartridge exit 11 to a cross section of said container 1. Said cross section of the receiving section 1 is larger than the cross section of the cartridge exit 11. The interface 8 is preferably implemented as a sleeve adapting different "calibers" of the cartridge 9 and the pressure input side 3.
[0041] In certain embodiments, the interface 8 is designed so, that commonly used receptacles can be used as the container 100 thus eliminating the need of producing custom-made containers 100. For example, PET soft- drink bottles can be used as a container 100 with an interface 8 designed to accommodate these. These PET bottles might need slight adaptations to provide said predetermined breaking region. This could be done be weakening a portion of the PET to ensure rupture upon the detonation of the explosive 6.
[0042] A further advantage of using commonly available receptacles as a container 100 is that these are easily available in large quantities almost anywhere, thus reducing the intervention time in some cases.
[0043] It is to be observed, that in some of the cases the container 1, the interface 8 and the cartridge 9 will be formed by one single piece designed so that it can perform all functions of each separate part, i.e. the cartridge 9 is strong enough to withstand the force of the detonation, the interface 8 is shaped so that pressure wave is transformed as needed and the receiving
section 1 is suitable for receiving and then releasing sufficient amounts of the physical agent 2.
[0044] However, in some cases it is preferred that the receiving section 1, the interface 8 and the cartridge 9 to be separate parts so that each can be replaced/ removed separately. This is preferred for example when the receiving section 1 is delivered ready-to use, i.e. filed with the physical agent 2 , and need only be attached to the rest of the dispersing device 10 to be used. An other case where a modular arrangement is advantageous is when the weak detonating explosive 6 comes readily built in the cartridge 9 part. [0045] The cartridge 9 is fixed into the pressure input side 3 via the interface 8, by fixation means 13. The most basic fixation means 13 as shown on figure 1 is a screw-on cap securing the aforementioned elements together.
[0046] The arrangement of the container 1, the interface 8 and the cartridge 9 as described above provides for a transformation of the pressure wave created by said weak detonating explosive 6 when activated into a pressure wave traveling through said physical agent 2. It is to be emphasized that the pressure wave travels through the physical agent 2 as opposed to prior art dispersing devices, where the physical agent 2 is propelled/ ejected by said pressure wave but said pressure wave does not travel through the physical agent 2. The effect of said pressure wave travelling through the physical agent 2 is that the physical agent 2 is pulse-pulverized upon release through said exit side 7. Additionally, the exhaust by-products created by the weak detonating explosive 6 when activated, are fully mixed with the physical agent 2 and are also pulse-pulverized together with it. This combined effect creates a so-called gasdispersive pressure vortex that ensures a universal, effective pulverizing on long distances, large areas and high volumes. It is to be observed that special arrangement of the container 1, the interface 8 and the cartridge 9 as described above further provides a cooling effect of said exhaust by-products before they are being mixed with the physical agent 2. [0047] Figure 2 shows a structural perspective-view of a first
embodiment of the activator 200 according to the present invention. It comprises an activator body 22, a connection interface 28 for mechanically/
releasably connecting the activator body 22 with the container 100 and a shock igniter 24 configured to exercise, when actuated, a high pressure on the weak detonating explosive 6 in order to activate it.
[0048] The activator body 22 is preferably a cylindrical body configured such as to be easily provided with the shock igniter 24. The activator body 22 could be made of any material; however, light-weight materials are especially preferred. The connection interface 28 is configured to mechanically/ releasably connect the activator body 22 with the container 100. For this reason, the connection interface 28 is shaped and sized according to the container(s) 100 to be used, especially to the pressure input side 3 of the container(s) to be connected . The connection interface 28 may optionally comprise fixation means such as a threaded portion to be connected with a corresponding threaded portion of the container 100. Similarly a so-called twist-lock arrangement may be provided wherein corresponding shapes of the connection interface 28 and of the container 100 are configured to interlock when one is twisted in relation to the other.
[0049] The shock igniter 24 is preferably a trigger-type spring loaded shock igniter, as known in the art for igniting explosives/ explosive cartridges. At the end of the shock igniter, a trigger pin 26 is preferably provided which is arranged so as to impact the cartridge 9 to cause an activation of the weak detonating explosive 6.
[0050] The security device 21 is provided to prevent accidental activation of the shock igniter 24. The security device may comprise a so- called twist-lock arrangement, wherein the shock igniter 24 is temporarily fixed in a secure position. The shock igniter 24 can be released from this secure position only upon a very specific movement, such that can not accidentally occur. Such as a twisting motion combined with a minimum axial pressure.
[0051] The shock absorbing means 24 is provided to absorb the shock from the weak detonating explosive 6 when triggered . The shock absorbing means 24 are positioned between said activator body 22 and said interface 28 so as to prevent that the shocks from the detonation of the weak detonating
explosive are transmitted to the activator body 22. The protection foam 25, preferably as a ring around the activator body 22 additionally improves the grip and shock absorption.
[0052] Fig. 3 depicts a structural perspective-view of a first embodiment of the dispersing device 10 according to the present invention. The assembly of the dispersing device 10 from the reusable activator 200 and the
disposable container 100 is well depicted on this figure. Preferably the two are screwed together by means of corresponding threaded portions of the interface 8 of the container 100 and of the connection interface 28 of the activator 200. As described before, a corresponding twist-lock arrangement can be provided as well.
[0053] On this same figure, the seal 7a, provided with a predetermined rupture zone, of the exit side 7 can be also seen. The predetermined rupture zone can be provided by means of a weakened portion of the seal 7, manufactured from a weaker material or made from the same material with a different structure, e.g . thinner to allow a controlled rupture upon expose to the pressure wave from the weak detonating explosive 6.
[0054] Figure 3 shows the preferred embodiment of the present invention, wherein both the container 100 and the activator 200 are
rotationally symmetric.
[0055] Figure 4A depicts a structural side-view of the same embodiment of the dispersing device according to the present invention. This figure is a so- called exploded view in order for all essential elements of the dispersing device 10, as assembled from the container 100 and the activator 200, to be clearly visible. It shall be kept in mind that once assembled the dispersing device 10 forms a compact stable unit. After use, the container 100 is disconnected from the activator 200 and disposed of. In a further embodiment of the present invention, the container fully or partially disintegrates upon use as a result of the activation of the weak detonating explosive 6. The activator 200 is reused with a new container 100.
[0056] Figure 4B shows a structural side-view of a first embodiment of the dispersing device according to the present invention as assembled . The connection between the pressure interface 8 of the container 100 and of the connection interface 28 of the activator 200 can be well seen in this figure. [0057] Figure 5 shows the dispersing device 10 as used for firefighting . In a first step a dispersing device 10 according to the present invention has to be provided . The receiving section 1 has to be filled with a suitable fire- extinguishing physical agent 2, and a weak detonating explosive 6 within a cartridge 9 has to be installed. Then the dispersing device 10 has to be directed with its exit side 7 towards the burning surface/ fire and the weak detonating explosive 6 has to be activated with the activator 200. Thus a pressure wave travelling through said physical agent 2 is created also providing for a mixing of exhaust by-products produced by said activation and the mixture is then pulse-pulverized and released through the exit side 7 thus extinguishing the fire. It is to be noted, that not only the physical agent 2 covering the burning surface extinguishes the fire, but the combined effect of the mixing of exhaust by-products, pulse pulverization of said physical agent 2 upon release and of the transformation of a pressure wave created by said weak detonating explosive 6 when activated into a pressure wave travelling through said physical agent which together create a so-called gasdispersive pressure vortex.
[0058] The use the dispersing device 10 for camouflage and/or crowd- control purposes is shown on figure 6. In this case the receiving section 1 of the dispersing device 10 is filled with a very light and loose, non-lethal physical agent 2 aimed to cause discomfort and/or reduce visibility of the targeted person. The physical agent 2 in these applications is one or a combination of non-lethal agents such as tear gas, pepper spray, sticky foam, or other incapacitants. When the dispersing device 10 is used for camouflage purposes, the physical agent 2 comprises some sort of loose opaque agent.
[0059] Figure 7 shows a pair of dispersing devices 10 as being used to treat a contaminated water surface. Testing has shown that in such
applications a pair of the dispersing devices 10 performs much better due to a
combined effect of opposite gasdispersive pressure vortexes. The pair of dispersing devices 10 is configured so, that the vortexes whirl in opposite directions thus providing for an increased dispersive effect ensuring a more efficient coverage. For this application the physical agent 2 comprises biosorbents such as microorganisms or biological agents to break down or remove the contamination.
[0060] It will be understood that many variations could be adopted based on the specific structure hereinbefore described without departing from the scope of the invention as defined in the following claims.
