6
Casings or casing connectors of metal or shape memory alloys for munitions, rockets, munition launch casings and containers for volatile or energetic substances, 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 rings; pressure reducing valves being parts of gas installations; metal safety valves (not being parts of machines); valves made of metal or shape memory alloys operated or activated by changes in pressure or heat; wire made of metal or shape memory alloys, including such wire which contracts on heating to rupture the surface beneath
9
Apparatus for suppressing explosions or spontaneous ignition of volatile or energetic substances; explosion or ignition prevention device in the nature of safety valves being part of or affixed to containers for volatile or energetic substances to allow release of pressure or heat; apparatus for cutting, buckling or piercing the casings of munitions, munition launch casings, rockets or containers for volatile or energetic substances to release pressure and or heat, namely a safety device made of shape memory alloys that cuts, buckles, pierces or ruptures the casing when exposed to fast or slow heating
13
Safety apparatus being part of or for affixing to rocket or munitions casings or munition launch casings to prevent unintentional detonation, namely a device to force open a valve or puncture the casing to release pressure or heat; munitions casings; munition launch casings; apparatus for preventing or suppressing explosions or spontaneous ignition of munitions or rockets, namely a device 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 to allow release of pressure or heat
