Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
89 words
A propellant gas generator comprising: an elongated closed housing; a line charge of explosive material sheathed within a metallic tubing and disposed axially within said housing substantially along the entire longitudinal axis thereof, said explosive line-charge material being a mixture comprising about 75 percent by weight of hexanitrostilbene, about 6 percent by weight of boron, about 17.6 percent by weight of potassium nitrate, and the remainder being essential binders, a propellant packed about said line charge, and means at one end of said housing for initiating said line charge.
Claim 2
Dependent Claim
