Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
36 words
The method as defined in claim 1 including thickening the ammonium nitrate and liquid water miscible organic fuel prior to reacting it with the slaked or unslaked lime by adding a thickening or gelling agent thereto.
Claim 2
Dependent Claim
98 words
The method as defined in claim 2 wherein sufficient ammonium nitrate, slaked or unslaked lime, liquid water miscible organic fuel, and additional water if necessary are mixed and reacted together to form a mixture comprising from about 10 to about 100 percent by weight of a mixture comprising from about 65 to about 85 percent by weight of calcium nitrate, from about 15 to about 35 percent by weight of a liquid water miscible organic fuel, and water in an amount to provide a weight ratio of water to calcium nitrate ranging from about 1/26 to about 2/1.
Claim 3
Dependent Claim
79 words
The method as defined in claim 1 wherein sufficient ammonium nitrate, slaked or unslaked lime, liquid water miscible organic fuel, and additional water, if necessary, are mixed and reacted to form an explosive composition comprising from about 5 to about 25 percent by weIght calcium nitrate; from about 10 to about 25 percent liquid water miscible organic fuel; from about 3 to about 8 percent water; and from about 50 to about 85 percent by weight of ammonium nitrate.
Claim 4
Dependent Claim
35 words
The method as defined in claim 4 including thickening the ammonium nitrate and liquid water miscible organic fuel by adding a thickening or gelling agent thereto prior to reacting it with slaked or unslaked lime.
Claim 5
Dependent Claim
30 words
The method as defined in claim 4 including mixing with said explosive composition during the manufacture thereof up to about 60 percent by weight of a particulate metallic fuel component.
