Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
66 words
A method of manufacturing a mixture of finely divided metals or alloys and solid perhalogenated carbon compounds capable of reaction upon ignition without the formation of gases or vapors, said method comprising forming a solution of said solid polyhalogenated carbon compounds in a solvent consisting of liquid perhalogenated compounds, dispersing said finely divided metal or alloy in said solution and removing said solvent from said solution.
Claim 2
Independent Claim
66 words
A method of manufacturing a mixture of finely divided metals or alloys and solid perhalogenated carbon compounds capable of reaction upon ignition without the formation of gases or vapors, said method comprising forming a solution of said solid polyhalogenated carbon compounds in a solvent consisting of liquid perhalogenated compounds, dispersing said finely divided metal or alloy in said solution and removing said solvent from said solution.
Claim 3
Dependent Claim
15 words
The method of claim 1 wherein the perhalogenated carbon compound contains chlorine and fluorine atoms.
