Gas generator device within an enclosure

Claim 2

A GAS GENERATOR DEVICE FOR AN ENCLOSURE COMPRISING A SEALED, FLEXIBLE, DEFORMABLE ENVELOPE WHICH, IN USE, IS SURROUNDED BY A HIGH PRESSURE REACTANT LIQUID AND INSIDE OF WHICH IS DISPOSED A SOLID GAS GENERATING MATERIAL FOR RELEASING A GAS WHEN IN CONTACT WITH THE REACTANT LIQUID, SAID ENVELOPE FURTHER CONTAINING A NON-REACTANT LIQUID, AND MEANS FOR TREATING SAID ENVELOPE AT A DESIRED TIME SO AS TO PUT SAID SOLID MATERIAL INTO CONTACT WITH SAID REACTANT LIQUID TO RELEASE SAID GAS INTO THE ENCLOSURE, SAID ENVELOPE TEARING MEANS COMPRISING AN EXPLOSIVE CHAGE AND SAID DEVICE FURTHER INCLUDING MEANS FOR PROVIDING REMOTE-CONTROLLED DENOTATION OF SAID CHARGE TO THEREBY CAUSE TEARING OF SAID ENVELOPE.

Claim 3

A device as in claim 1, wherein said solid material is a hydride that reacts with water to produce hydrogen.

Claim 4

A device as in claim 1 wherein said non-reactant liquid in the envelope comprises a mineral oil.

Claim 5

A device as in claim 1, wherein said deformable envelope comprises a pouch.

Claim 6

A gas generating device comprising a reaction chamber furnished in its lower part with an opening for the passage of a liquid and in its upper part with an orifice for the passage of a gas, an enclosure surmounted above said reaction chamber positioned to receive gas from said reaction chamber, a sealed, flexible deformable envelope inside said reaction chamber which, in use, is surrounded by a reactant liquid which enters said chamber through said opening and inside of which is disposed a solid gas generating material for releasing a gas when in contact with the reactant liquid, said envelope further containing a non-reactant liquid and means for tearing said envelope at a desired time, to put said solid material into contact with the liquid in said reaction chamber to release said gas through said orifice into said enclosure, said envelope tearing means comprising an explosive charge, and said device further including means for providing remote-controlled detonation of said charge to thereby cause tearing of said envelope.

Claim 7

A gas generating device comprising a reaction chamber furnished in its lower part with an opening for the passage of a liquid and in its upper part with an orifice for the passage of a gas, an enclosure surmounted above said reaction chamber positioned to receive gas from said reaction chamber, a sealed, flexible deformable envelope inside said reaction chamber which, in use, is surrounded by a reactant liquid which enters said chamber through said opening and inside of which is disposed a solid gas generating material for releasing a gas when in contact with the reactant liquid, said envelope further containing a non-reactant liquid and means for tearing said envelope at a desired time, to put said solid material into contact with the liquid in said reaction chamber to release said gas through said orifice into said enclosure, said envelope tearing means comprising an explosive charge, and said device further including means for providing remote-controlled detonation of said charge to thereby cause tearing of said envelope.

Claim 8

A gas generator device for an enclosure comprising a sealed, flexible, deformable envelope which, in use, is surrounded by a high pressure reactant liquid and inside of which is disposed a solid gas generating material for releasing a gas when in contact with the reactant liquid, said envelope further containing a non-reactant liquid, said device further comprising means for tearing said envelope at a desired time so as to put said liquid material into contact with said reactant liquid to release said gas into The enclosure, said envelope tearing means comprising an explosive charge and said device further including means for providing remote-controlled denotation of said charge to thereby cause tearing of said envelope.

Claim 9

A gas generator device for an enclosure comprising a sealed, flexible, deformable envelope which, in use, is surrounded by a high pressure reactant liquid and inside of which is disposed a solid gas generating material for releasing a gas when in contact with the reactant liquid, said envelope further containing a non-reactant liquid, said device further comprising means for tearing said envelope at a desired time so as to put said liquid material into contact with said reactant liquid to release said gas into The enclosure, said envelope tearing means comprising an explosive charge and said device further including means for providing remote-controlled denotation of said charge to thereby cause tearing of said envelope.

Claim 10

A device as claimed in claim 6 wherein said non-reactant liquid comprises a mineral oil and said deformable envelope comprises a pouch.
