Abstract: A method for the manufacture of primers/detonators with 90-99.99% reliability and achieving sensitivity of 0.8 inch-oz to 3.0 inch-oz, able to withstand temperatures within the range of 40.degree. C. to 200.degree. C. and able to withstand temperature cycling and humidity for 95% RH at 95.degree. C. to -40.degree. C. Mechanical and chemical sensitizers are utilized in lieu of tetracene, the utilization of oxidizers as sensitizers, the utilization of high energy fuels, and a method of co-precipitating the primary explosive and mechanical sensitizer.

Abstract: A method of producing explosive for priming explosive devices by reacting components in situ in a device.

Abstract: Production of styphnate and azide explosives in situ in explosive devices including both ammunition and detonators particularly, though not exclusively, involving formation of premixes of relatively insensitive materials.

Abstract: A flame-explosion couple is disclosed which upon ignition burns for a period of time in a relatively stable manner and thereafter explodes to produce fragments which continue to burn for a further period of time. The composition may comprise from 40 to 89 percent by weight of a volatile liquid fuel, from 10 to 50 percent by weight of a secondary explosive or strong metal salt oxidizer and from 0.5 to 5 percent by weight of an explosive primer. It is usually desirable to incorporate a gellant in the composition to give it a jellylike consistency of a desired viscosity. The composition may optionally contain combustible metal powders and combustible polymers.
