Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
44 words
An explosive composition comprising: a low density carbonaceous absorbent formed at least in part from comminuted, processed cellulose; a liquid explosive absorbed onto the low-density, carbonaceous absorbent, said carbonaceous absorbent remaining substantially chemically unchanged after absorption of the liquid explosive; and an oxygen-supplying salt.
Claim 2
Dependent Claim
44 words
An explosive composition comprising: a low density carbonaceous absorbent formed at least in part from comminuted, processed cellulose; a liquid explosive absorbed onto the low-density, carbonaceous absorbent, said carbonaceous absorbent remaining substantially chemically unchanged after absorption of the liquid explosive; and an oxygen-supplying salt.
Claim 3
Dependent Claim
15 words
An explosive composition as in claim 1, wherein the comminuted, processed cellulose is ground paper.
Claim 4
Dependent Claim
15 words
An explosive composition as in claim 1, wherein the comminuted, processed cellulose is ground newsprint.
Claim 5
Dependent Claim
25 words
An explosive composition as in claim 1, wherein the comminuted, processed cellulose is present at from about 1 to 30 weight percent of the composition.
Claim 6
Dependent Claim
22 words
An explosive composition as in claim 1, wherein the comminuted, processed cellulose is present at from about 4 to 10 weight percent.
Claim 7
Dependent Claim
74 words
An improved explosive composition of the type including a liquid explosive at from 5 to 93 weight percent, a carbonaceous absorbent at from 1 to 30 weight percent, and an oxygen-supplying salt at from 5 to 50 weight percent, wherein said liquid explosive is absorbed by said carbonaceous absorbent without substantial chemical modification of said absorbent, and, wherein said improvement is forming at least a portion of the carbonaceous absorbent from comminuted, processed cellulose.
Claim 8
Dependent Claim
74 words
An improved explosive composition of the type including a liquid explosive at from 5 to 93 weight percent, a carbonaceous absorbent at from 1 to 30 weight percent, and an oxygen-supplying salt at from 5 to 50 weight percent, wherein said liquid explosive is absorbed by said carbonaceous absorbent without substantial chemical modification of said absorbent, and, wherein said improvement is forming at least a portion of the carbonaceous absorbent from comminuted, processed cellulose.
Claim 9
Dependent Claim
25 words
An improved explosive as in claim 6, wherein the processed cellulose is paper ground in a high speed hammer mill with 1/8 inch screen openings.
Claim 10
Dependent Claim
21 words
An improved explosive composition as in claim 6, wherein the processed cellulose is present at from 4 to 10 weight percent.
Claim 11
Dependent Claim
18 words
An improved explosive composition as in claim 6, further including nitrocellulose at up to about 5 weight percent.
