Abstract: A missile launch cannister end cap removal device utilizing the pressure pulse of a traveling shock wave within the cannister is disclosed. A pressure chamber, the interior of which is separated from the interior of the cannister by a diaphragm having a selected rupture pressure. Gas pressure is generated in the chamber by the firing of an explosive charge at the appropriate time in the missile launch sequence. The diaphragm is ruptured by the pressure developed in the chamber introducing a traveling shock wave into the interior of the missile cannister. The pressure pulse of the shock wave removes the end caps fitted over the open ends of the cannister.

Abstract: An actuating rod is locked firmly in position by a split spring locking ring which engages matching shoulders in a groove on the rod. An electrical signal operates to energize a squib gas generator which produces pressure forcing a piston inward unlocking the ring and engaging wedge faces on the split locking ring causing the ring to spread open and release the actuating rod which moves upward in response to the forces of an extension spring. When locked, the rod has great resistance to imposed axial and side loads.

The striker is rotatable from a `Safe` position to an `Armed` position, and movable axially, by impact, from the `Armed` position to a `Fire` position. A resilient detent prevents movement from the `Armed` to the `Fire` position unless the applied impact force exceeds a predetermined value. Further resilient detents prevent unintentional arming of the device.

Abstract: A decoy flare cartridge for use in an aircraft photoflash cartridge rack. drocarbon compound plus gelling agents are placed in a photoflash cartridge. A primer in the base of the cartridge is fired to propel a piston which forces the gel out of the cartridge through an orifice plate.

Abstract: A signaling device to be launched underwater having a fuze body and a protile containing pyrotechnic compositions. The pyrotechnic compositions are ignited by an electrical squib which is detonated by voltage from a sea water battery which is sealed from sea water until a valve opens to permit entry of water into the fuze. An open circuit is provided between the battery and leads of the squib and, in addition, the squib leads are shorted. The opening of a valve to permit entry of sea water into the fuze causes the short to be removed and closes the circuit between the battery and the squib.

Abstract: A self-scuttling buoyant pyrotechnic marine marker. A scuttling pellet of incendiary composition is provided adjacent the pyrotechnic candle, to be ignited as the candle becomes spent and to burn a hole in the side of the jacket, or to clear impurities or residue which may have built up during burning of the candle to block the smoke or flame emission hole of the marker. Scuttling is then virtually assured by simple wave action. In this way, the hazard of spent markers being washed ashore to pose a danger to humans or to pollute the environment is reduced.

Abstract: A chemiluminescent lighting apparatus for generating an illuminated marker aterial for delivery to a desired area. Two fluids to be mixed are contained in separate chambers and are separated from a mixing chamber by means of frangible disc-shaped members. A hollow gas generator expells gas when a squib fractures one of its walls. The force of the escaping gas exerts pressure on the two fluids sufficient to fracture the frangible disc members allowing mixing action in the mixing chamber. The mixed fluid chemically reacts to produce light and flows from the mixing chamber to a light transmittable material where it is stored to provide an illuminated area.
