Abstract: A heat seeking missile decoy device mounted on a military vehicle to change the infrared signature of the military vehicle. The device is at ambient temperature when stored on the military vehicle. When a heat seeking missile is fired at the military vehicle, the decoy device deploys and increases in temperature, changing the infrared signature of the vehicle and causing a hot spot away from vulnerable components of the vehicle. The hot spot radiates in the infrared in an area that is away from vulnerable parts of a military vehicle, drawing the heat seeking missile toward it. The termination trajectory of the heat seeking missile is at the end of the decoy device and not the vulnerable parts of the military vehicle. The energy required to heat the device is passive waste energy from the vehicle engine exhaust.

Abstract: Fluoroalkylsilane-coated metal particles having a central metal core, a buffer layer surrounding the core, and a fluoroalkylsilane layer attached to the buffer layer are prepared by combining a chemically reactive fluoroalkylsilane compound with an oxide coated metal particle having a hydroxylated surface. The resulting fluoroalkylsilane layer that coats the particles provides them with excellent resistance to aging. The particles can be blended with oxidant particles to form energetic powder that releases chemical energy when the buffer layer is physically disrupted so that the reductant metal core can react with the oxidant.

Abstract: A portable metal-cutting pyrotechnic torch comprising a solid thermite fuel for pyrotechnics, an igniter and a thermally non-conducting handle. Further provided is a tubular body which preferably burns away with the composition.
Abstract: The invention relates to a tow body for representing a flying target by means of infrared flares, the infrared flares being situated on the rear of the tow body and being ejectable by the tow body and being pulled by the tow body by means of a reel-off towing cable during burning time. According to the invention, a drop unit (1) for the burned-up IR flares is arranged on the rear of the tow body, which drop unit (1) comprises a circular receiving unit (7) which is rotatably disposed and constructed under a retaining plate (8), for the towing cable nipples (17) forming the tow-body-side end of the towing cable, after the burning-up of an infrared flare, the corresponding towing cable nipple (17) connected with the infrared flare being released by a rotation of the receiving unit (7).
Abstract: Barrel assembly (10) includes rifled barrel (11) loaded with several pyrotechnic projectiles (12) for selective firing by an electronically controlled system. Each projectile (12) includes body (14), housing (15) containing pyrotechnic material (16), and trailing collar (17) supported on trailing hub (18) of body (14) for limited axial movement. Collar (17) includes leading wall (20) abutting trailing wall (21) of housing (15) and an internally tapered thickened rear part (24) engaging nose (25) of trailing projectile (12) to wedge into sealing engagement with barrel (11). Hub (18) supports propellant capsule (30) connected by electrical leads (31) to contacts (32) on outer cylindrical wall (33) of housing (12). Complementary contacts (34) are supported in barrel (11). Alignment of contacts (34) with contacts (32) occurs during the loading process. Fuse (35) extends between capsule (30) and primer (36) so that material (16) explodes a set time after firing projectile (12) from barrel (11).
Abstract: The idea of an exploding target which is sold in “two parts” and is not classified as an explosive until a catalyst is added to the main target, is a completely unique idea which increases the safety of the exploding target and also allows the product to be safely shipped in a “non-hazardous” form. The benefits of this “binary” approach are obvious. Law enforcement and qualified ranges will have a safer reactive target to shoot at during qualification and the targets aren't bound to restrictive storage requirements as set forth by Code of Federal Regulations.
Abstract: A closure for a pyrotechnic unit ensures that upon the build-up of pressure of a pyrotechnic charge (24) no pieces which fly off occur. That is achieved in that the cover (4) has a desired-rupture location (32) in the form of a circular ring, except for a portion (14), wherein the residual cover (36) which tears open is non-detachably connected to the cover (4).
Abstract: This invention is for an improved sparkler which has the feature of being self-igniting. The sparkler comprises a rod 12 having one end which functions as a handle 14. Adjacent to the handle 14 on the rod 12 and extending generally along the remaining length of the rod 12 is a pyrotechnic composition coating 16. Bonded to the pyrotechnic composition coating 16 at a point furthest from the handle 14 is a self-igniting match head tip 18. When the match head tip 18 is struck against a suitable surface, ignition occurs and the sparkler's display begins. This self-ignition feature distinguishes the invention from the sparklers currently available which require heat or flame from an external source to be applied to the sparkler to cause ignition.

Abstract: Compositions are provided which, when burned, produce significant levels of infrared radiation, but only limited levels of visible radiation. The basic components of the compositions include a binder, an oxidizer, and a fuel, where the binder also acts the fuel. Preferred oxidizers include those compounds which produce large quantities of infrared radiation when the flare composition is burned. Such oxidizers include potassium nitrate, cesium nitrate, rubidium nitrate, and combinations of these compounds. Selection of the binder is important in order to provide the composition with the desirable characteristics identified above. The binder of the present invention does not produce significant soot. At the same time, the binder serves to form a composition which is processible, avoids chunking, and is compatible with the oxidizers used. It has been found that polymer binders which include relatively short carbon chains (1-6 continuous carbon atoms) are preferred.

Preferably, the first hydrogen rich material comprises a material capable of providing nitrogen upon decomposition thereof, and the second metal material comprises a material capable of reacting exothermically with the nitrogen generated by the decomposition of the first material such that the solid phase comprises a solid nitride of the second metal material.In a preferred embodiment, the first material comprises ammonium azide, and the second material comprises boron, titanium, titanium hydride, or mixture thereof.
Abstract: The present invention is directed to the encapsulation of pyrophoric materials in a high temperature resistant membrane having at least one perforation which allows air to contact the pyrophoric material. By controlling the accessibility of the pyrophoric material to the surrounding air, it is possible to reduce the kinetics of the oxidation reaction without affecting the thermodynamics of the reaction. This results in a product that demonstrates a lower peak temperature, longer dwell time at the lower temperature and, in most cases, an increase in the total heat energy output in comparison to an identical pyrophoric material that is not so encapsulated.

Abstract: A cylindrical metal end cap is formed over one end of a thermoplastic tubular casing. A pyrotechnic detonator is ohmically connected to the end cap via an aperture thereof and includes an electrically activated match. The detonator is soldered to the end cap with a solder ring simultaneously with the insertion of the detonator into the end cap aperture to form a hermetic seal. A thermoplastic end cap is heat welded to the other end of the casing to hermetically seal the pyrotechnic material within the casing. The heat welding occurs at the outer surface of the casing and at a temperature lower than the ignition temperature of the pyrotechnic material in the casing. The position of the match within the casing is selected to cause the pyrotechnic material to burn toward the metal end cap to enhance flash production, different length casings producing different flash intensities.
