Claims Analysis
Total Claims: 26
Claim 1
Independent Claim
67 words
A consumable cartridge comprising: (a) a primer; and (b) a projectile; and (c) a molded cartridge case containing means for receiving said primer and means for receiving said projectile in association therewith for use in a firearm, said molded cartridge case comprising a composition made from an inorganic nitrate oxidizer and an organic acid selected from the group consisting of erythorbic acid, ascorbic acid, and mixtures thereof.
Claim 2
Dependent Claim
67 words
A consumable cartridge comprising: (a) a primer; and (b) a projectile; and (c) a molded cartridge case containing means for receiving said primer and means for receiving said projectile in association therewith for use in a firearm, said molded cartridge case comprising a composition made from an inorganic nitrate oxidizer and an organic acid selected from the group consisting of erythorbic acid, ascorbic acid, and mixtures thereof.
Claim 3
Dependent Claim
59 words
The consumable cartridge of claim 1 wherein the inorganic nitrate and organic acid are present in the molded cartridge in amounts, which when compared to the total weight of these two constituents, the nitrate comprises from about 50% to about 75% by weight and the acid comprises from about 25% to 50% by weight, before the cartridge is molded.
Claim 4
Dependent Claim
13 words
The consumable cartridge of claim 2 wherein the inorganic nitrate is potassium nitrate.
Claim 5
Dependent Claim
82 words
The consumable cartridge case comprising: a molded cartridge case containing means for receiving a primer and means for receiving a projectile in association therewith suitable for use in a firearm, said molded cartridge case having a generally cylindrical shape and containing a composition prepared from a mixture of an inorganic nitrate oxidizer selected from the group consisting of potassium nitrate, ammonium nitrate and mixtures thereof, and an organic acid selected from the group consisting of erythorbic acid, ascorbic acid and mixtures thereof.
Claim 6
Dependent Claim
82 words
The consumable cartridge case comprising: a molded cartridge case containing means for receiving a primer and means for receiving a projectile in association therewith suitable for use in a firearm, said molded cartridge case having a generally cylindrical shape and containing a composition prepared from a mixture of an inorganic nitrate oxidizer selected from the group consisting of potassium nitrate, ammonium nitrate and mixtures thereof, and an organic acid selected from the group consisting of erythorbic acid, ascorbic acid and mixtures thereof.
Claim 7
Dependent Claim
54 words
The consumable cartridge case of claim 4 wherein the inorganic nitrate and acid are present in the molded cartridge case in amounts which when compared to the total weight of these two constituents, the nitrate comprises from about 50% to 75% by weight and the acid comprises from about 25% to 50% by weight.
Claim 8
Independent Claim
71 words
A method of making a consumable cartridge comprising the steps of (1) forming a slurry and solution of an oxidizer and an organic acid; (2) drying the slurry and solution mixture at a temperature below about 175° F. (79° C.); and (3) compacting the dried mixture in a mold to a preselected shape using between 10,000 lbs. per square inch and 14,000 lbs. per square inch to form the finished shape.
Claim 9
Independent Claim
71 words
A method of making a consumable cartridge comprising the steps of (1) forming a slurry and solution of an oxidizer and an organic acid; (2) drying the slurry and solution mixture at a temperature below about 175° F. (79° C.); and (3) compacting the dried mixture in a mold to a preselected shape using between 10,000 lbs. per square inch and 14,000 lbs. per square inch to form the finished shape.
Claim 10
Dependent Claim
25 words
The method of claim 6 wherein said step of compacting includes heating the mixture while compacting to a temperature less than 175° F. (79° C.).
Claim 11
Dependent Claim
22 words
The method of claim 7 wherein the oxidizer is potassium nitrate and the acid is erythorbic acid, ascorbic acid or mixtures thereof.
Claim 12
Dependent Claim

(79° C.); and (3) compacting the dried mixture in a mold to a preselected generally hollow cylindrical shape using between 10,000 lbs. per square inch and 14,000 lbs. per square inch to form the finished shape.
Claim 14
Independent Claim
75 words
A method of making a consumable cartridge case comprising the steps of (1) forming a slurry and solution of an oxidizer and an organic acid; (2) drying the slurry and solution mixture at a temperature below about 175° F. (79° C.); and (3) compacting the dried mixture in a mold to a preselected generally hollow cylindrical shape using between 10,000 lbs. per square inch and 14,000 lbs. per square inch to form the finished shape.
Claim 15
Dependent Claim
24 words
The method of claim 10 wherein said step of compacting includes heating the mixture while compacting to a temperature less than 175° 79° C.).
Claim 16
Dependent Claim
22 words
