Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
89 words
A gas-containing means comprising (a) a pressure resistant vessel having a valved port, (b) at least one collapsible structure in said vessel enclosing unavailable space, said structure being impermeable to solids and being collapsible at a stress less than the stress sufficient to plastically deform said vessel; and (c) a multiplicity of solid, gas absorbing particles in said vessel occupying, when in the gas-free state, substantially less than the available space in said vessel, and, when in the gas-charged state, no greater than the available space in said vessel.
Claim 2
Dependent Claim
89 words
A gas-containing means comprising (a) a pressure resistant vessel having a valved port, (b) at least one collapsible structure in said vessel enclosing unavailable space, said structure being impermeable to solids and being collapsible at a stress less than the stress sufficient to plastically deform said vessel; and (c) a multiplicity of solid, gas absorbing particles in said vessel occupying, when in the gas-free state, substantially less than the available space in said vessel, and, when in the gas-charged state, no greater than the available space in said vessel.
Claim 3
Dependent Claim
25 words
A gas-containing means as in claim 1 wherein said vessel contains a multiplicity of collapsible structures relatively uniformly distributed throughout the volume of said vessel.
Claim 4
Dependent Claim
40 words
A gas-containing means as in claim 1 wherein said vessel contains a multiplicity of collapsible structures distributed within said vessel so as to be higher in concentration near the bottom of said vessel than in other parts of said vessel.
Claim 5
Dependent Claim
19 words
A gas-containing means as in claim 1 wherein said at least one collapsible structure is a resilient collapsible structure.
Claim 6
Dependent Claim
59 words
A gas-containing means as in claim 1 wherein the collapsible structure is a perforated metallic tube positioned axially in said vessel, extended substantially the length of said vessel, closed at one end and having the other end thereof connected to said valved port so as to provide a means of passage of gas to and from said valved port.
Claim 7
Dependent Claim
17 words
A gas-containing means as in claim 2 wherein the collapsible structures are hollow metal or plastic items.
Claim 8
Dependent Claim
14 words
A gas-containing means as in claim 2 wherein the collapsible structures are foamed structures.
Claim 9
Dependent Claim
25 words
A gas-containing means as in claim 3 wherein the collapsible structures are mounted on an armature means to provide the proper disposition of the structures.
