    Abstract: The present invention relates to a gas generator (10) comprising a body (12) delimiting at least one part of a combustion chamber (20), said part housing a primary pyrotechnic charge (16) adapted to generate gases in the combustion chamber (20) when said charge is initiated in combustion, and a slide valve (60) located outside said body (12) and defining with the latter a second chamber (66) housing a secondary pyrotechnic charge (74) whereof the self-ignition temperature is less than that of the primary pyrotechnic charge (16). A gas flow channel (50) for flowing gas out of the combustion chamber (20) is formed in the body (12). According to the invention, the slide valve (60) blocks this channel when it is in a first position, and under the effect of gases released by said secondary pyrotechnic charge (74), the slide valve is adapted to move to a second position wherein the channel (50) is no longer sealed off, allowing the gases contained in the combustion chamber (20) to flow outwards to the exterior.

  • Patent number: 7669742
    Abstract: A tactical device holster (TDH) system is described that is a complete carry and deployment solution allowing for split-second deployment of hand-held non-lethal/lethal deployable devices (HNLDD) by tactical personnel. The TDH system allows tactical personnel to deploy HNLDDs without having to disarm because deployment requires only a single hand, and the TDH system indexes the HNLDD in the proper position for deployment. The TDH system allows the HNLDD to go from secure carry to deployment in under one second while not impeding the deadly force option during deployment. The TDH system keeps the fuze lever of the HNLDD fixed in a pre-specified position. The HNLDD is not altered for use with the TDH system and allows quick insertion of the HNLDD. The TDH system supports numerous HNLDDs and tactical pyrotechnic and incendiary devices, and can be fixed to various tactical clothing, vests, holsters, equipment, and vehicle components.

The launching member, configured for receiving at least one elongated pyrotechnic device, presents a closed lower end and an open upper end, and includes a retaining collar, retaining nut, and a friction band. The support structure presents a support face, having positioning slots for positioning the elastomeric bands, and an opening defined therein for receiving the open upper end of the launching member. The support structure is secured to the launching member by receiving the open upper end of the launching member through the opening, the support structure being retained between the retaining collar and retaining nut.

  • Patent number: 5526751
    Abstract: A flare including a body, an ignitable projectile in the body, an igniter for initiating ignition of the ignitable projectile and initiating propulsion of the projectile out one end of the body, a cap removably coupled to the other end of the body and an ignition member in the body and the cap which can be pulled to ignite the igniter composition. The flare also includes a safety shield at least partially receiving the body and the cap and being releasably retained against substantial axial movement relative to the body in a retracted position to inhibit removal of the cap from the body and being responsive to a force to move relative to the body and cap to an extended position. Confronting surfaces of the shield and cap are configured to provide a passage for water to escape from a region between the shield and the body. The end of the shield adjacent the body is configured to provide a plurality of resilient fingers.

  • Patent number: 4771695
    Abstract: A holder for fireworks comprising a pair of rigid uprights of sheet material and a number of rigid plates or shelves of sheet material extending between the uprights. Slots in the respective components provide for assembly into a self-supporting fireworks holder by the relative telescoping of the uprights through the slots. Legs of sheet construction are also telescoped through slots in the upright and interlock with slits in the baseplate to rigidify the structure. Holes in some of the plates hold the fireworks in position for firing. The baseplate is substantially free of holes to serve as a shield to prevent inadvertent ignition of materials proximal to the holder.

  • Patent number: 4724768
    Abstract: A line throwing rocket arrangement is disclosed which is normally stored in a generally rectangular case. The set includes at least one rocket provided with a guide sleeve generally integral with the body of the rocket but disposed exteriorly thereof. During the launching, the sleeve slides over a straight guide rod. The storage case is provided with suitable means for securement of the guide rod to the box at different angles so that different ranges can be covered by the rocket in rescue or the like operations can be covered. The advance in the art is primarily in the simplified arrangement which facilitates the operation and reduces the manufacturing costs of the set.

  • Patent number: 4697518
    Abstract: A pyrotechnic device having a maximum explosive effect with a minimum quantity of explosive composition. The device is in the form of a polyurethane plastic foam body molded about a firecracker tube. The firecracker tube contains a small explosive composition charge therein and into which a fuse extends. The tube is sealed at each end by packing means. A polyurethane sealant coating is provided over the tube to seal any openings in the tube and any openings in any interface between the tube, the packing means and the fuse. The sealant serves as a good engaging surface to which the body portion of plastic foam will adhere when molded. When completed, the plastic foam body has a predetermined shape, such as cylindrical, generally spherical, or multifaceted.
