Casings or casing connectors of metal or shape memory metal alloys for containers for volatile or energetic substances, namely, gases, liquids, explosives, pyrotechnics or powders, including such casings and casing connectors that differentially expand or contract on heating to release a joint or valve thereby avoiding pressure build up and ignition or explosion; pressure or heat actuated metal rings for releasing pressure and/or heat from munitions casings, munition launch casing, rockets or containers for volatile or energetic substances, namely, gases, liquids, explosives, rockets, pyrotechnics and powders; valves made of metal or shape memory metal alloys operated or activated by changes in pressure or heat; wire made of metal or shape memory metal alloys, including such wire which contracts on heating to rupture the surface beneath

Explosion or ignition prevention device in the nature of safety valves that can be part of or affixed to containers for volatile or energetic substances, namely, gases, liquids, explosives, pyrotechnics and powders, to allow release of pressure or heat

Safety apparatus being part of or for affixing to rocket or munitions casings or munition launch casings to prevent unintentional deflagration or detonation, namely, a device made of shape memory metal alloys to force open a valve or puncture the casing to release pressure or heat, in the form of a wire, casing connector, casing seal or ring which contracts with exposure to pressure or heat to rupture the surface beneath; munitions casings; munition launch casings; apparatus for preventing or suppressing explosions or spontaneous ignition of munitions or rockets, namely, a device made of shape memory metal alloys in the form of a wire, casing connector, casing seal or ring activated by temperature or pressure to open a joint or outlet in the casing or body of the munitions or rocket; explosion or ignition prevention device in the nature of safety valves being part of or affixed to casings for munitions, rockets, munition launch casings or containers for volatile or energetic substances, namely, gases, liquids, explosives, pyrotechnics and powders, to allow release of pressure or heat; casings or casing connectors of metal or shape memory metal alloys for munitions, rockets and munition launch casings including such casings and casing connectors that differentially expand or contract on heating to release a joint or valve thereby avoiding pressure build up and ignition or explosion
