Abstract
Abstract A pressurized-gas vessel, especially for acetylene and gases soluble in a solvent, which comprises a pressure-retentive metal container, a body of porous material within the container and spaced from a wall thereof to form an intervening space, and a mass of sintered material filling this space and constituting a flame barrier and shock-wave attenuator to prevent explosion of the gas within the vessel while mechanically retaining the mass of porous material against breakdown during handling and transportation of the vessel.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
97 words
A pressurized-gas tank for an explosive gas, soluble in a solvent, comprising: a pressure-retentive vessel having an outlet and at least one wall surrounding the space within said vessel; a porous mass adapted to receive said solvent and said gas in said space in said vessel and spaced with all-around clearance from said wall thereof to form with said wall an annular intervening space communicating with said outlet and surrounding said porous mass; and a body of fine-grained particles sintered together and filling said annular intervening space whereby the body of sintered particles envelops said porous mass.
Claim 2
Dependent Claim
97 words
A pressurized-gas tank for an explosive gas, soluble in a solvent, comprising: a pressure-retentive vessel having an outlet and at least one wall surrounding the space within said vessel; a porous mass adapted to receive said solvent and said gas in said space in said vessel and spaced with all-around clearance from said wall thereof to form with said wall an annular intervening space communicating with said outlet and surrounding said porous mass; and a body of fine-grained particles sintered together and filling said annular intervening space whereby the body of sintered particles envelops said porous mass.
Claim 3
Dependent Claim
21 words
The pressurized-gas tank defined in claim 1 wherein said body is chemically inert with respect to said gas and said solvent.
Claim 4
Dependent Claim
24 words
The pressurized-gas tank defined in claim 1 wherein said body has a melting point below the decomposition temperature of said gas and said solvent.
Claim 5
Dependent Claim

The pressurized-gas tank defined in claim 1 wherein said body is composed of metal particles.
Claim 6
Dependent Claim
96 words
A pressurized-gas tank for an explosive gas, soluble in a solvent, comprising: a pressure-retentive vessel; a porous mass adapted to receive said solvent and said gas in said vessel and spaced from at least one wall thereof to form with said wall an intervening space; and a body of fine-grained metal particles sintered together and filling said space, said metal particles having the following composition: 5 to 7 percent by weight silicon 0.1 to 0.3 percent by weight magnesium 0.3 to 0.6 percent by weight manganese, and 3 to 5 percent by weight copper, balance aluminum.
Claim 7
Dependent Claim
96 words
A pressurized-gas tank for an explosive gas, soluble in a solvent, comprising: a pressure-retentive vessel; a porous mass adapted to receive said solvent and said gas in said vessel and spaced from at least one wall thereof to form with said wall an intervening space; and a body of fine-grained metal particles sintered together and filling said space, said metal particles having the following composition: 5 to 7 percent by weight silicon 0.1 to 0.3 percent by weight magnesium 0.3 to 0.6 percent by weight manganese, and 3 to 5 percent by weight copper, balance aluminum.
Claim 8
Independent Claim
78 words
A method of making a pressurized-gas tank, comprising the steps of: a. pouring an aqueous slurry of a hardenable material into a pressure-retentive vessel; b. driving off water from said slurry and hardening same to produce a porous solvent-absorptive mass shrinking away from a wall of said vessel to define a space therewith; c. filling said space with finely divided particles of a sinterable material; and d. heating said vessel to sinter said particles into a porous body.
Claim 9
Independent Claim
78 words
A method of making a pressurized-gas tank, comprising the steps of: a. pouring an aqueous slurry of a hardenable material into a pressure-retentive vessel; b. driving off water from said slurry and hardening same to produce a porous solvent-absorptive mass shrinking away from a wall of said vessel to define a space therewith; c. filling said space with finely divided particles of a sinterable material; and d. heating said vessel to sinter said particles into a porous body.
Claim 10
Dependent Claim
25 words
The method defined in claim 6 wherein said particles are introduced into said space by forcing the particles into said vessel under a pressure differential.
Claim 11
Dependent Claim
36 words
The method defined in claim 7 wherein said pressure differential is sufficient to expand said vessel, said method further comprising the step of relaxing the pressure in said vessel to retain said porous mass under compression.
Claim 12
Dependent Claim
35 words
The method defined in claim 6, further comprising the step of maintaining the interior of said vessel under pressure during the introduction of said particles into said space and during sintering of said particles together.
Claim 13
Dependent Claim
23 words
The method defined in claim 6, further comprising the step of mechanically densifying said particles in said space prior to sintering said particles.
