Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 122 words
A flexible, self-supporting explosive composition of high power and brisance composed essentially entirely of explosive ingredients and consisting essentially of a. about from 50 to 90 weight percent of a particulate high explosive selected from the group consisting of cyclotrimethylenetrinitramine, cyclotetramethylenetetranitramine and pentaerythritol tetranitrate and mixtures thereof having an average particle size not exceeding about 25 microns; and b. about from 10 to 50 weight percent of a binder system consisting essentially of high viscosity nitrocellulose containing about from 12.1 to 12.5 percent nitrogen, and triethyleneglycol dinitrate plasticizer; wherein the amount of said nitrocellulose is about from 1 to 8 weight percent of the composition and the weight ratio of said plasticizer to said nitrocellulose is about from 4:1 to 7:1, respectively.
Claim 2
Dependent Claim 122 words
A flexible, self-supporting explosive composition of high power and brisance composed essentially entirely of explosive ingredients and consisting essentially of a. about from 50 to 90 weight percent of a particulate high explosive selected from the group consisting of cyclotrimethylenetrinitramine, cyclotetramethylenetetranitramine and pentaerythritol tetranitrate and mixtures thereof having an average particle size not exceeding about 25 microns; and b. about from 10 to 50 weight percent of a binder system consisting essentially of high viscosity nitrocellulose containing about from 12.1 to 12.5 percent nitrogen, and triethyleneglycol dinitrate plasticizer; wherein the amount of said nitrocellulose is about from 1 to 8 weight percent of the composition and the weight ratio of said plasticizer to said nitrocellulose is about from 4:1 to 7:1, respectively.
Claim 3
Dependent Claim 130 words
A flexible, self-supporting explosive composition of high power and brisance adapted for use as a flexible sheet explosive, composed essentially entirely of explosive ingredients and consisting essentially of: a. about from 50 to 70 weight percent of a particulate high explosive selected from the group consisting of cyclotrimethylenetrinitramine, cyclotetramethylenetetranitramine and pentaerythritol tetranitrate and mixtures thereof having an average particle size not exceeding about 25 microns; and b. about from 30 to 50 weight percent of a binder system consisting essentially of high viscosity nitrocellulose containing about from 12.1 to 12.5 percent nitrogen, and triethyleneglycol dinitrate plasticizer; wherein the amount of said nitrocellulose is about from 4 to 8 weight percent of the composition and the weight ratio of the plasticizer to the nitrocellulose is about from 4:1 to 7:1, respectively.
Claim 4
Dependent Claim 130 words
A flexible, self-supporting explosive composition of high power and brisance adapted for use as a flexible sheet explosive, composed essentially entirely of explosive ingredients and consisting essentially of: a. about from 50 to 70 weight percent of a particulate high explosive selected from the group consisting of cyclotrimethylenetrinitramine, cyclotetramethylenetetranitramine and pentaerythritol tetranitrate and mixtures thereof having an average particle size not exceeding about 25 microns; and b. about from 30 to 50 weight percent of a binder system consisting essentially of high viscosity nitrocellulose containing about from 12.1 to 12.5 percent nitrogen, and triethyleneglycol dinitrate plasticizer; wherein the amount of said nitrocellulose is about from 4 to 8 weight percent of the composition and the weight ratio of the plasticizer to the nitrocellulose is about from 4:1 to 7:1, respectively.
Claim 5
Dependent Claim 39 words
The composition of claim 2, wherein the weight ratio of the plasticizer to the nitrocellulose is about from 5:1 to 6:1, respectively, and the amount of the nitrocellulose is about from 4 to 6 weight percent of the composition.
