Abstract

The invention relates to a novel method for preserving and protecting a very large number of articles of any type: chemical, medical, dehydrated food products, any type of fabric, paper, antiques and works of art, wood, leather, explosives, cereals and starches, fodder, etc., against oxygen in the air, humidity, insects, rodents, aging, self-explosion, fires, etc. This invention consists in placing the articles to be preserved in hermetically closed preservation chambers from which air has been sucked out as much as possible, then replaced by any inert gas coming from a gas tank joined to the preservation chamber. This inert gas remains mixed with the articles throughout the preservation. In order to add or withdraw articles, the inert gas is first withdrawn from the preservation chamber by means of a pump and compressed into the same above mentioned tank, then air is let in in order to replace the gas, after which the chamber is opened. This method also allows the use of the same quantity of gas an infinite number of times, and in addition does not cause any pollution of the surrounding air.

Description

La présente invention concerne une nouvelle méthode de conservationi et de protection de beaucoup d'articles les périodes de stockage et de conservation. Cette méthode se base sur le principe de l'évacuation de l'air suivi par le passage d'un gaz inerte quelconque dans un cycle clos. The present invention relates to a new method of conservation and protection of many articles during periods of storage and conservation. This method is based on the principle of air evacuation followed by the passage of any inert gas in a closed cycle.

Tous les articles sont généralement attaqués par différents genres d'insectes qui leur sont propres, spécialement pendant les périodes de stockage, d'a,lmagasinage ou de consetvation. D'autres articles sont très sensibles à l'oxygène de l'air/et sont rapidement desinfectés à peine éxposés à l'air atmosphérique naturel.D'autres articles sont exposés à des auto-éxplosions, d'autres sont sensibles à l'humidité, d'autres sont toujours attaqués par les animaux rongeurs et d'autres sont exposés aux incendies .... etc. All items are generally attacked by different kinds of insects of their own, especially during periods of storage, storage, storage or preservation. Other items are very sensitive to air / oxygen and are rapidly disinfected when barely exposed to natural atmospheric air. Other items are exposed to self-explosion, others are sensitive to humidity, others are always attacked by rodent animals and others are exposed to fire .... etc.

La présente invention vise à protéger et sauvegarder un nombre incalculable d'objets et d'articles contre beaucoup d'éléments tels que : - L'air atmosphérique - L'humidité - L'oxygène de l'air - Les insectes - Les animaux rongeurs - Le vieillissement - La détérioration naturelle - Les incendies - Les auto-éxplosions etc.  The present invention aims to protect and save countless objects and articles against many elements such as: - Atmospheric air - Humidity - Oxygen in the air - Insects - Rodent animals - Aging - Natural deterioration - Fires - Self-explosions etc.

A quoi consiste cette nouvelle méthode?
A - La mise des objets dans une chambre de conservation ou de protection
qui puisse être hérmétiquement férmée
La chambre de conservation peut être sous forme de caisse, dépôt,
vitrine, silos, cellule, armoire, chambre ....etc. l'essentiel qu'elle
soit une place hermétiquement fermée, et elle peut être aussi en des
differentes formes, differentes tailles et differentes capacités.- Dehydrated fruits and vegetables - Dehydrated milk - Forage and pasture
... and many other articles
What does this new method consist of?
A - Putting objects in a conservation or protection chamber
that can be hermetically closed
The conservation chamber can be in the form of a box, deposit,
showcase, silos, cell, wardrobe, bedroom .... etc. the essential that she
either a hermetically sealed place, and it can also be in
different shapes, different sizes and different capacities.

B - Au moyen d'une pompe aspirante refoulante jointe à la chambre de con
servation , l'air est aspiré de l'interieur de la chambre de conser
vation et rejeté à l'exterieur jusqu'àl'évacuation maximum de l'air.B - By means of a pressure suction pump attached to the con chamber
servation, air is drawn from inside the storage room
vation and rejected outside until the maximum air evacuation.

C - D'un réservoir de gaz, joint à la chambre de conservation, le gaz
de nitrogène ou un autre gaz inérte , ou un mélange d'un gaiinerte
avec dHtz inerte, ce gaz ou ce mélange va naturellement passer du
réservoir à la chambre de conservation à travers un robinet d'arrêt
comme résultat naturel de la différence de pression , jusqu'à ce que
la pression du gaz de nitrogène ou l'autre à l'interieur de la cham
bre de conservation soit égale à la pression atmosphérique naturelle
environnante, après quoi le robinet d'arrêt est fermé
D - Ce gaz inerte, mentionné ci-dessus, reste dans la chambre tout le
temps de la conservation, mélangé et entourant les différents objets
ou articles.C - From a gas tank, attached to the preservation chamber, the gas
nitrogen or another inert gas, or a mixture of a gaiinerte
with inert dHtz, this gas or mixture will naturally pass from
tank to the preservation chamber through a stopcock
as a natural result of the pressure difference, until
the pressure of the nitrogen gas or the other inside the cham
conservation period is equal to natural atmospheric pressure
surrounding, after which the shut-off valve is closed
D - This inert gas, mentioned above, remains in the room for the entire
conservation time, mixed and surrounding different objects
or articles.

E - Pour retirer ou ajouter un ou plusieurs articles de l'interieur de
la chambre de conservation , le gaz inerte utilisé est d'abord re
tiré totalement de l'interieur de la chambre de conservation au moyen
de la pompe aspirante refoulante mentionnée ci-dessus, puis pressé à
l'interieur du même reservoir à gaz; ensuite à travers un second ro
binet d'arrêt, on laisse entrer l'air atmosphérique exterieur dans la
chambre de conservation jusqu'à ce que la pression de l'air soit égale
à la pression atmosphérique exterieure
F - Aprés avoir ajouté ou retiré les articles voulus, l'air est aspiré de
nouveau de la chambre de la conservation et rejeté à l'exterieur, puis
le gaz inerte déjà utilisé, arrive du même réservoir où il avait été
préssé( dans la phase E ) pour remplacer l'air et rester de nouveau
dans la chambre de conservation, mélangé et protégeant tous les
articles consérvés Cette méthode permet non seulement de supprimer la présence de
chambres l'oxygène de l'air à llinterieur deslde conservation. ce qui ne permet à aucune insecte ou à aucun animal rongeur de subsister, mais aussi elle aide à éliminer totalement toute occasion d'auto-explosion ou d'incendie
Ainsi que cette méthode permet d'utiliser la même quantité de gaz inerte ( nitrogène ou autre ) un nombre infini de fois, tant qu'il n'y a pas eu de fuite de gaz; car le gaz va du reservoir à la chambre de conservation et retourne de la chambre de conservation au reservoir , et par conséquent empêche aucune perte de gaz ainsi qu'elle empêche la polution de l'air environnant
Cette invention est une méthode de stockage et de conservation d'un
nombre incalculable d'articles. Elle peut être industrialisée en des
differentes formes, differentes tailles et avec des differentes matières.E - To remove or add one or more items from inside
the storage chamber, the inert gas used is first re
taken entirely from inside the preservation chamber using
of the pressure suction pump mentioned above, then pressed
the interior of the same gas tank; then through a second ro
shut-off valve, the outside atmospheric air is allowed to enter the
storage chamber until the air pressure is equal
at outside atmospheric pressure
F - After adding or removing the desired items, the air is drawn in
new from the conservation chamber and rejected outside then
the inert gas already used, arrives from the same tank where it had been
pressed (in phase E) to replace the air and stay again
in the storage chamber, mixed and protecting all
saved items This method not only eliminates the presence of
air oxygen chambers inside the storage tank. which does not allow any insect or rodent animal to survive, but also helps to completely eliminate any opportunity for self-explosion or fire
As this method allows to use the same amount of inert gas (nitrogen or other) an infinite number of times, as long as there was no gas leakage; because the gas goes from the reservoir to the conservation chamber and returns from the conservation chamber to the reservoir, and consequently prevents any loss of gas as well as it prevents the pollution of the surrounding air
This invention is a method of storing and preserving a
countless number of articles. It can be industrialized in
different shapes, different sizes and with different materials.

Cette méthode peut être industrialisée et employée pour la protection
et la conservation des differents articles dans les moyens de transport
maritimes, terrestres et aériens
Les dessins annexés illustrent l'invention.This method can be industrialized and used for protection
and the conservation of the various articles in the means of transport
sea, land and air
The accompanying drawings illustrate the invention.

( La figure 1 représente les étapes de la mise en pratique de cette mé
thode ) ( La figure 2 présente une démonstration d'une mise en pratique de cette méthode )
En référence à ces dessins, les differents articles sont mis à l'interieur de la chambre de conservation (1) . La porte (2) est ensuite hermétiquement fermée de façon à ne permettre aucune fuite d'air ou de gaz de l'interieurde la chambre de conservation
Les robinets d'arrêt (9, 10, 11 X fermés et les robinets d'arrêt ( 5, 6, 7 et 8 ) ouvertes , l'air est aspiré de ls'interieur de la chambre de conservation (1) à travers les robinets d'arrêt (5, 6 ) au moyen drune pompe aspirante refoulante (3) et rejeté à l'exterieur à travers les robinets d'arrêt (7, 8) pour arriver à l'évacuation maximum de l'air à l'interieur de la chambre (1) . (Figure 1 represents the stages of the implementation of this mé
thode) (Figure 2 shows a demonstration of how to use this method)
With reference to these drawings, the various articles are placed inside the preservation chamber (1). The door (2) is then hermetically closed so as to allow no leakage of air or gas from inside the preservation chamber.
The shut-off valves (9, 10, 11 X closed and the shut-off valves (5, 6, 7 and 8) open, the air is drawn from inside the preservation chamber (1) through the shut-off valves (5, 6) by means of a pressure suction pump (3) and discharged outside through the shut-off valves (7, 8) to achieve maximum air evacuation at the interior of the chamber (1).

Les robinets d'arrêt (6, 7, 8, 10, 11). fermés, et les robinets (5, 9) ouvertes permettent à un gaz inerte quelcovque, comme le nitrogèae ou un mélange d'un gaz inerte avec un autre gaz inerte de passer du reservoir à gaz (4) à la chambre ai conservacion (1) , jusqu'à ce que la pression du gaz à l'interieur de la chambre de conservation(l) soit égale à la pression atmosphérique naturelle environante .Ce gaz inerte ou ce mélange reste alors à l'interieur de la chambre de conservation mélangé et entourant tous les articles tout le temps de la conservation
Pour ajouter ou retirer des quantités quelconques des articles conservés , les robinets d'arrêt (8, 9, 11) fermés et les robinets d'arrêt (5, 6, 7, 10) ouverts, le gaz inerte employé est d'abord retiré totalement de la chambre de conservation (1) au moyen de la pompe aspirante refoulante (3) et pressé à l'interieur de son reservoir (4) ensuite à travers le robinet d'arrêt (11) ouvert, l'air atmosphérique entre auto natiquement dans la chambre de conservation (1) jusqu'à ce que la pression de l'air à l'interieur de la chambre (1) soit égale à la pression atmosphérique exterieure
La porte (2) est alors ouverte et permet d'ajouter ou de retirer les quantités d'articles voulus
Pour la reconservation , les mêmes étapes mentionnées ci-dessus sont reprises dans je mena ordre Stop valves (6, 7, 8, 10, 11). closed, and the taps (5, 9) open allow any inert gas, such as nitrogen or a mixture of an inert gas with another inert gas, to pass from the gas tank (4) to the storage chamber (1 ), until the pressure of the gas inside the preservation chamber (l) is equal to the surrounding natural atmospheric pressure. This inert gas or this mixture then remains inside the mixed preservation chamber and surrounding all items all the time from conservation
To add or remove any quantities from the stored items, the shut-off valves (8, 9, 11) closed and the shut-off valves (5, 6, 7, 10) open, the inert gas employed is first removed completely from the preservation chamber (1) by means of the suction suction pump (3) and pressed inside its reservoir (4) then through the open stopcock (11), the atmospheric air enters natively in the preservation chamber (1) until the air pressure inside the chamber (1) is equal to the external atmospheric pressure
The door (2) is then open and allows adding or removing the quantities of desired articles
For the re-preservation, the same steps mentioned above are repeated in the order
