- FIG. 13 shows a schematic sectional end view of the fluid pressurization device of FIG. 12 , in an inflated condition thereof.
- a fluid pressurization device in accordance with the invention is designated generally by the reference numeral 10 .
- the fluid pressurization 10 comprises, broadly, a pressure container 12 and a first bladder element 18 , that are located within the pressure container 12 .
- the pressure container 12 is in the form of a flexible bag of stitched fabric. It will be appreciated that the bag, while being flexible, has a fixed maximum volume when in a fully open condition.
- the pressure container 12 has two ends 20 and 22 with the end 22 being narrower than the end 20 . As such, the pressure container 12 has a generally frusto-conical configuration when fully open.
- the end 20 of the pressure container 12 defines an opening 24 . 1 and the end 22 defines an opening 24 . 2 .
- the first bladder 14 is of resiliently deformable rubber and has two ends 26 and 28 .
- the first bladder has a shape and dimensions identical to the shape and dimensions of the pressure container 12 .
- the first bladder 14 defines an opening 30 at its end 26 in which a pipe connector 32 including a tyre valve 33 , is located.
- the second bladder 16 is of resiliently deformable rubber and has a first end 34 and a second end 36 .
- the second bladder 16 has a shape and dimensions identical to the shape and dimensions of the pressure container 12 .
- the second bladder 16 has an opening 38 at its end 36 in which a pipe connector 40 including a tyre valve 39 , is located.
- the sheet element 18 is of flexible fabric and has two ends 42 and 44 .
- the fabric is formed by taking a rectangular sheet of fabric material and cuffing off the corners of the sheet near its end 44 , thereby providing the sheet element 18 with a tapered region 46 near its end 44 .
- the first and second bladders are located in the pressure container adjacent one another with the pipe connector 32 of the first bladder 14 extending through the hole 24 . 1 of the pressure container 12 and the pipe connector 40 of the second bladder 16 extending through the hole 24 . 2 of the pressure container 12 .
- the first and second bladders are located in the container with narrower ends thereof being disposed at the narrower end 22 of the pressure container.
- the second bladder 16 is folded in concertina fashion wherein folds of the bladder overlap one another as is shown in FIG. 6 of the drawings.
- the sheet element 18 is wrapped around the folded second bladder 16 to form a roll surrounding the bladder in an arrangement wherein portions of the sheet element 18 overlap and contact one another.
- the sheet element is rolled up around the folded second bladder 16 in an arrangement wherein the sheet element 18 contacts an inner side of the pressure container 22 and the first bladder 14 . More particularly, the sheet element 18 is wrapped around the folded second bladder 16 in an arrangement wherein the tapered region 46 of the sheet element is disposed at the narrower end 34 of the second bladder 16 .
- the fluid pressurization device 10 is used in an ordinance deflagration device in accordance with the second aspect of the invention.
- an ordnance deflagration device in accordance with the invention is designated generally in the drawings by the reference numeral 50 .
- the ordnance deflagration device 50 comprises the fluid pressurization device 10 , a torch 52 defining an outlet nozzle 53 , that is connected via a delivery pipe 54 to the pipe connector 32 extending from the first bladder 14 and to a canister containing liquefied butane under pressure, via a delivery pipe 58 .
- the pipe 58 has a valve 46 for controlling the flow of butane gas from the canister 56 to the torch 52 .
- the first bladder 14 is filled with oxygen to a pressure of 0.4 bar gauge pressure and the second bladder 16 is filled with compressed air to a pressure of 7 bar gauge pressure.
- oxygen being a volatile gas
- the lower pressure of the oxygen makes the fluid pressurization device 10 safe for use in applications wherein it will be subjected to relatively rough handling.
- the butane and the pressurized oxygen are mixed at the nozzle 53 of the torch 52 , to produce a high temperature flame when ignited.
- the pipe 54 has a valve 47 for controlling the flow of oxygen to the torch 52 .
- opening of the valve 47 allows pressurized oxygen to be discharged from the first bladder 14 into the delivery pipe 54 for mixing with the butane gas at the torch 52 .
- the first bladder decreases in volume and as a result, the frictional forces acting on the second bladder decreases.
- the second bladder expands within the pressure container 12 exerting a force on the first bladder 14 for pressurizing the oxygen contained therein.
- the frusto-conical shape of the pressure container 12 and of the first and second bladders 14 and 16 and the tapered shape of the sheet element 18 assist in maintaining a near constant pressure of the oxygen within the first bladder 14 .
- the frictional forces acting between the overlapping regions of sheet element 18 in a hoop direction at the tapered region 46 of the sheet element are relatively less than the frictional forces acting in a hoop direction between the overlapping portions of the sheet element at the opposite end 42 , thereby causing the sheet element 18 to unravel relatively faster at the end 44 than at the end 42 of the sheet element.
- the effect of the gradual unraveling of the sheet element ensures that a nearly constant pressure is maintained on the oxygen in the bladder 14 .
- the relatively greater force that is exerted on the first bladder 14 at its end 28 ensures that oxygen contained within the first bladder 14 is forced towards the wider end 26 of the first bladder (the end at which the pipe connector 32 is located) to ensure that oxygen is not trapped in pockets within the bladder 14 as the second bladder expands within the pressure container 22 to take up the space within the pressure container 22 left by the shrinking bladder 14 .
- FIG. 11 of the drawings another embodiment of an ordnance deflagration device in accordance with the invention is designated generally by the reference numeral 60 .
- the device 60 is similar to the device 50 with the only difference being that the canister 56 is replaced with a second fluid pressure device.
- the device 60 thus includes two fluid pressurization devices 10 . 1 and 10 . 2 for delivering volatile combustible gases to the torch 52 where the gases are mixed and ignited, in use.
- the bladder 14 of fluid pressurization device 10 . 1 is inflated with oxygen to a gauge pressure of 0.4 bar
- the bladder 14 of fluid pressurization device 10 . 2 is inflated with liquid petroleum gas to a gauge pressure of 0.4 bar.
- the bladders 16 of the devices 10 . 1 and 10 . 2 are inflated with compressed air to a gauge pressure of 7 bar.
- FIGS. 12 and 13 of the drawings another embodiment of a fluid pressurization device in accordance with the invention, is designated generally the reference numeral 100 .
- the device 100 is the same as the device 10 with the only difference being that an additional inflatable bladder 114 is located in the pressure container 12 adjacent the bladder 14 at a side thereof remote from the bladder 16 .
- the bladder 114 has a similar frusto-conical shape to that of the bladder 14 and has a connector pipe 132 including a tyre valve, through which the bladder 114 can be filled and fluid discharged therefrom, in use.
- the fluid pressurization device 100 can be used in an ordnance deflagration device to deliver two combustible fluids to a torch where the combustible fluids can be mixed and ignited to produce a high temperature flame. More particularly, as for the fluid pressurization device 100 , the bladder 16 is filled with compressed air to gauge pressure of 7 bar and the bladder 14 is filled with oxygen to a gauge pressure of 0.4 bar. The bladder 114 is filled with liquid petroleum gas which is not pressurized, i.e. the liquid petroleum gas is at a pressure of 1 bar within the bladder.
- Delivery pipes are connected to the pipe connectors 31 and 32 , respectively for connecting the bladders 14 and 114 to a torch in an arrangement similar to that of the ordnance deflagration device 60 illustrated in FIG. 11 of the drawings.
- the bladder 16 exerts a force on the bladder 14 which in turn exerts a force on the bladder 114 for pressurizing the fluid contained within each of the bladders 14 and 114 .
- a near constant delivery of combustible fluid can be achieved from the bladders 14 and 114 .
- the torch 52 of the ordnance deflagration devices 50 and 60 can be directed at the outer casing of an unexploded ordnance device such a land mine or a mortar shell.
- the high temperature flame delivered by the torch 52 softens the outer casing and burns therethrough igniting the contents.
- high explosive contained within the casing is suspended in an inflammable matrix Once ignited, the matrix will burn through using the high explosive contained therein for wicking. Unexploded ordinance can thus be deflagrated rendering it safe without an explosion.
- the ordnance deflagration device in accordance with the invention will thus obviate the need to detonate exploded ordinance causing damage to the terrain and contamination of the area with explosive material which will in itself cause difficulty in the search for further unexploded ordinance.

Abstract
A fluid pressurization device 10 comprises a pressure container 12 and a first bladder 14, a second bladder 16 and a sheet 18, that are located in the pressure container 12. The bladders 14 and 16 have pipe connectors 32 and 40, respectively, for filling/discharging fluid from the bladders. The bladders 14 and 16 are located in the container 12 adjacent one another, with the bladder 16 being folded in concertina fashion and the sheet 18 being wrapped around the bladder 16 to form a roll surrounding the folded bladder 16. In use, the bladder 14 is filled with a combustible fluid such as oxygen and the bladder 16 is filled with compressed air to a relatively higher pressure than the oxygen in the bladder 14 for pressurizing the oxygen contained therein. As oxygen is delivered from bladder 14, the sheet 18 unravels gradually, allowing the bladder 16 to continue to exert a force on the bladder 14.

FIG. 13 shows a schematic sectional end view of the fluid pressurization device ofFIG. 12 , in an inflated condition thereof. - with reference to the drawings, a fluid pressurization device in accordance with the invention, is designated generally by the
reference numeral 10. Thefluid pressurization 10 comprises, broadly, apressure container 12 and afirst bladder element 18, that are located within thepressure container 12. - The
pressure container 12 is in the form of a flexible bag of stitched fabric. It will be appreciated that the bag, while being flexible, has a fixed maximum volume when in a fully open condition. Thepressure container 12 has twoends end 22 being narrower than theend 20. As such, thepressure container 12 has a generally frusto-conical configuration when fully open. Theend 20 of thepressure container 12 defines an opening 24.1 and theend 22 defines an opening 24.2. - The
first bladder 14 is of resiliently deformable rubber and has twoends pressure container 12. Thefirst bladder 14 defines anopening 30 at itsend 26 in which apipe connector 32 including atyre valve 33, is located. - The
second bladder 16 is of resiliently deformable rubber and has afirst end 34 and asecond end 36. Thesecond bladder 16 has a shape and dimensions identical to the shape and dimensions of thepressure container 12. Thesecond bladder 16 has anopening 38 at itsend 36 in which apipe connector 40 including atyre valve 39, is located. - The
sheet element 18 is of flexible fabric and has twoends end 44, thereby providing thesheet element 18 with atapered region 46 near itsend 44. - The first and second bladders are located in the pressure container adjacent one another with the
pipe connector 32 of thefirst bladder 14 extending through the hole 24.1 of thepressure container 12 and thepipe connector 40 of thesecond bladder 16 extending through the hole 24.2 of thepressure container 12. - The first and second bladders are located in the container with narrower ends thereof being disposed at the
narrower end 22 of the pressure container. Thesecond bladder 16 is folded in concertina fashion wherein folds of the bladder overlap one another as is shown inFIG. 6 of the drawings. Thesheet element 18 is wrapped around the foldedsecond bladder 16 to form a roll surrounding the bladder in an arrangement wherein portions of thesheet element 18 overlap and contact one another. As such, the sheet element is rolled up around the foldedsecond bladder 16 in an arrangement wherein thesheet element 18 contacts an inner side of thepressure container 22 and thefirst bladder 14. More particularly, thesheet element 18 is wrapped around the foldedsecond bladder 16 in an arrangement wherein the taperedregion 46 of the sheet element is disposed at thenarrower end 34 of thesecond bladder 16. - In a particular application, the
fluid pressurization device 10 is used in an ordinance deflagration device in accordance with the second aspect of the invention. With reference toFIG. 10 of the drawings, an ordnance deflagration device in accordance with the invention, is designated generally in the drawings by thereference numeral 50. Theordnance deflagration device 50 comprises thefluid pressurization device 10, atorch 52 defining anoutlet nozzle 53, that is connected via adelivery pipe 54 to thepipe connector 32 extending from thefirst bladder 14 and to a canister containing liquefied butane under pressure, via adelivery pipe 58. Thepipe 58 has avalve 46 for controlling the flow of butane gas from thecanister 56 to thetorch 52. - The
first bladder 14 is filled with oxygen to a pressure of 0.4 bar gauge pressure and thesecond bladder 16 is filled with compressed air to a pressure of 7 bar gauge pressure. As such, it is be appreciated that oxygen, being a volatile gas, is pressurized to a relatively much lower pressure then the non-volatile compressed air, the lower pressure of the oxygen makes thefluid pressurization device 10 safe for use in applications wherein it will be subjected to relatively rough handling. The butane and the pressurized oxygen are mixed at thenozzle 53 of thetorch 52, to produce a high temperature flame when ignited. Thepipe 54 has avalve 47 for controlling the flow of oxygen to thetorch 52. - Frictional forces acting between the overlapping portions of the
sheet element 18 and thesecond bladder 16 in a hoop direction and frictional forces acting between the sheet element and thepressure container 22 and thefirst bladder 14, respectively, resist unrolling of thesheet element 18, thereby holding thesecond bladder 16 in its folded condition. In use, opening of thevalve 47 allows pressurized oxygen to be discharged from thefirst bladder 14 into thedelivery pipe 54 for mixing with the butane gas at thetorch 52. As the oxygen in thefirst bladder 14 is delivered to thetorch 52, the first bladder decreases in volume and as a result, the frictional forces acting on the second bladder decreases. As a consequence, the second bladder expands within thepressure container 12 exerting a force on thefirst bladder 14 for pressurizing the oxygen contained therein. The frusto-conical shape of thepressure container 12 and of the first andsecond bladders sheet element 18 assist in maintaining a near constant pressure of the oxygen within thefirst bladder 14. - The frictional forces acting between the overlapping regions of
sheet element 18 in a hoop direction at the taperedregion 46 of the sheet element, are relatively less than the frictional forces acting in a hoop direction between the overlapping portions of the sheet element at theopposite end 42, thereby causing thesheet element 18 to unravel relatively faster at theend 44 than at theend 42 of the sheet element. This allows thesecond bladder 16 to exert a relatively greater force on thefirst bladder 14 at itsnarrower end 28 relative to itswider end 26. The effect of the gradual unraveling of the sheet element ensures that a nearly constant pressure is maintained on the oxygen in thebladder 14. Further, the relatively greater force that is exerted on thefirst bladder 14 at itsend 28 ensures that oxygen contained within thefirst bladder 14 is forced towards thewider end 26 of the first bladder (the end at which thepipe connector 32 is located) to ensure that oxygen is not trapped in pockets within thebladder 14 as the second bladder expands within thepressure container 22 to take up the space within thepressure container 22 left by the shrinkingbladder 14. - With reference to
FIG. 11 of the drawings, another embodiment of an ordnance deflagration device in accordance with the invention is designated generally by thereference numeral 60. InFIG. 11 , features of thedevice 60 that are the same and/or similar to those of thedevice 50, are designated by the same and/or similar reference numerals. Thedevice 60 is similar to thedevice 50 with the only difference being that thecanister 56 is replaced with a second fluid pressure device. - The
device 60 thus includes two fluid pressurization devices 10.1 and 10.2 for delivering volatile combustible gases to thetorch 52 where the gases are mixed and ignited, in use. In this example, thebladder 14 of fluid pressurization device 10.1 is inflated with oxygen to a gauge pressure of 0.4 bar, while thebladder 14 of fluid pressurization device 10.2 is inflated with liquid petroleum gas to a gauge pressure of 0.4 bar. Thebladders 16 of the devices 10.1 and 10.2 are inflated with compressed air to a gauge pressure of 7 bar. - With reference to the
FIGS. 12 and 13 of the drawings, another embodiment of a fluid pressurization device in accordance with the invention, is designated generally thereference numeral 100. InFIGS. 12 and 13 , features of thedevice 100 that are the same and/or similar to those of thedevice 10 are designated by the same and/or similar reference numerals. Thedevice 100 is the same as thedevice 10 with the only difference being that an additionalinflatable bladder 114 is located in thepressure container 12 adjacent thebladder 14 at a side thereof remote from thebladder 16. Thebladder 114 has a similar frusto-conical shape to that of thebladder 14 and has aconnector pipe 132 including a tyre valve, through which thebladder 114 can be filled and fluid discharged therefrom, in use. - The Applicant envisages that the
fluid pressurization device 100 can be used in an ordnance deflagration device to deliver two combustible fluids to a torch where the combustible fluids can be mixed and ignited to produce a high temperature flame. More particularly, as for thefluid pressurization device 100, thebladder 16 is filled with compressed air to gauge pressure of 7 bar and thebladder 14 is filled with oxygen to a gauge pressure of 0.4 bar. Thebladder 114 is filled with liquid petroleum gas which is not pressurized, i.e. the liquid petroleum gas is at a pressure of 1 bar within the bladder. Delivery pipes are connected to thepipe connectors 31 and 32, respectively for connecting thebladders ordnance deflagration device 60 illustrated inFIG. 11 of the drawings. When thebladders pressure container 12, thebladder 16 exerts a force on thebladder 14 which in turn exerts a force on thebladder 114 for pressurizing the fluid contained within each of thebladders fluid pressurization device 10, a near constant delivery of combustible fluid can be achieved from thebladders - The
torch 52 of theordnance deflagration devices torch 52 softens the outer casing and burns therethrough igniting the contents. Typically, high explosive contained within the casing is suspended in an inflammable matrix Once ignited, the matrix will burn through using the high explosive contained therein for wicking. Unexploded ordinance can thus be deflagrated rendering it safe without an explosion. The ordnance deflagration device in accordance with the invention will thus obviate the need to detonate exploded ordinance causing damage to the terrain and contamination of the area with explosive material which will in itself cause difficulty in the search for further unexploded ordinance.
