Abstract
Abstract A container for a volume of explosive powder is provided with a volumetric void within the mass of the powder in the area thereof capable of creating a burning rate equal to the mass detonation rate of the powder upon ignition of the powder. The void is formed by a volumetric member positioned within the mass of the powder, the member being arranged so as to prevent powder from sifting into the void. The void provides a volume for accumulation of combustion gases sufficient to prevent the gas pressure within a burning mass of powder from increasing to the point wherein the mass detonation rate of the powder mass is reached. Thus the ignited mass of powder merely burns itself up without detonating.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
103 words
A container for holding a volume of smokeless powder material sufficiently large to contain a critical area wherein ignition of the material can result in attainment of the mass detonation rate of the material, said container including an interior wherein the volume of material is disposed; and means in said interior of said container operative to form a volumetric void proximate to the critical area of the Volume of material, said volumetric void being operative to receive combustion heat and gas after ignition of the material in the critical area to prevent attainment of the mass detonation rate of burning of the material.
Claim 2
Dependent Claim
103 words
A container for holding a volume of smokeless powder material sufficiently large to contain a critical area wherein ignition of the material can result in attainment of the mass detonation rate of the material, said container including an interior wherein the volume of material is disposed; and means in said interior of said container operative to form a volumetric void proximate to the critical area of the Volume of material, said volumetric void being operative to receive combustion heat and gas after ignition of the material in the critical area to prevent attainment of the mass detonation rate of burning of the material.
Claim 3
Dependent Claim
103 words
A container for holding a volume of smokeless powder material sufficiently large to contain a critical area wherein ignition of the material can result in attainment of the mass detonation rate of the material, said container including an interior wherein the volume of material is disposed; and means in said interior of said container operative to form a volumetric void proximate to the critical area of the Volume of material, said volumetric void being operative to receive combustion heat and gas after ignition of the material in the critical area to prevent attainment of the mass detonation rate of burning of the material.
Claim 4
Dependent Claim
103 words
A container for holding a volume of smokeless powder material sufficiently large to contain a critical area wherein ignition of the material can result in attainment of the mass detonation rate of the material, said container including an interior wherein the volume of material is disposed; and means in said interior of said container operative to form a volumetric void proximate to the critical area of the Volume of material, said volumetric void being operative to receive combustion heat and gas after ignition of the material in the critical area to prevent attainment of the mass detonation rate of burning of the material.
Claim 5
Dependent Claim
91 words
A package comprising: a. a container; b. a volume of smokeless powder material in said container, said volume being sufficiently large to contain a critical area wherein ignition of the material can result in attainment of the mass detonation rate of burning of the material; and c. volumetric means in said volume of material, said volumetric means being operative to provide a volumetric void proximate to said critical area whereby said void can receive combustion heat and gas to prevent attainment of the mass detonation rate of burning of the material.
Claim 6
Dependent Claim
91 words
A package comprising: a. a container; b. a volume of smokeless powder material in said container, said volume being sufficiently large to contain a critical area wherein ignition of the material can result in attainment of the mass detonation rate of burning of the material; and c. volumetric means in said volume of material, said volumetric means being operative to provide a volumetric void proximate to said critical area whereby said void can receive combustion heat and gas to prevent attainment of the mass detonation rate of burning of the material.
Claim 7
Dependent Claim
93 words
A package comprising: a. container means; b. a volume of smokeless powder material in said container means, said volume being sufficiently large to have a critical area wherein ignition of the material can result in attainment of the mass detonation rate of burning of the material; and c. hollow volumetric body mean positioned within said volume of material and forming a volumetric void proximate to said critical area of said material whereby said void can receive combustion gas and heat to prevent attainment of the mass detonation rate of burning of the material.
Claim 8
Dependent Claim
93 words
A package comprising: a. container means; b. a volume of smokeless powder material in said container means, said volume being sufficiently large to have a critical area wherein ignition of the material can result in attainment of the mass detonation rate of burning of the material; and c. hollow volumetric body mean positioned within said volume of material and forming a volumetric void proximate to said critical area of said material whereby said void can receive combustion gas and heat to prevent attainment of the mass detonation rate of burning of the material.
Claim 9
Dependent Claim
28 words
The package of claim 3, wherein said body means is formed from a fast burning substance, and is operative to seal said void against leakage of said material.
Claim 10
Dependent Claim
22 words
The package of claim 3, wherein said body means is secured to said container means and held in a fixed position therein.
Claim 11
Dependent Claim
26 words
The package of claim 3 wherein said body means is an open ended tubular member having its ends closed by opposite sides of said container means.
