摘要： A concealed amalgamated neutralizer covertly combines neutralizer material comprised of various combinations of inert materials such as calcium carbonate or silicates with common explosive material for the prevention of malicious use of the explosive material in improvised explosive devices. The concealed amalgamated neutralizer device may vary in shape, size, and color and is therefore adaptable to varying methods of containment typified by common pyrotechnic products. The neutralizer material mimics the explosive material of the pyrotechnic products without detection. Upon disassembly of a concealed amalgamated neutralizer device, the neutralizer material is mixed with and neutralizes the explosive material rendering the explosive material useless as a component for an improvised explosive device. A biodegradable container is also provided for the amalgamated neutralizer and the explosive material.

摘要： The present technology is directed to igniter pellets for use with an expendable countermeasure flare assembly with an igniter assembly with a pellet receptacle. An igniter pellet of one or more embodiments has a moisture insensitive first layer formed by a first composition comprising a mixture of a fuel material that includes Boron, an oxidizer material that includes Bismuth Oxide and/or Potassium Perchlorate, and a granular matrix binder holding the fuel material and the oxidizer material together. A second layer is formed by a second composition that has a fuel material that includes Magnesium, an oxidizer that includes Polytetrafluoroethylene, and a binder material that includes a fluoropolymer elastomer. The second layer is contained in the pellet receptacle and covered by the first layer, so that the second layer is isolated and protected from ambient moisture by the moisture insensitive first layer.

摘要： The invention is directed to a co-layered propellant grain having an exposed outer surface, wherein said propellant grain comprises an outer layer comprising a slow burning propellant composition located on essentially the entire outer surface of the grain, and an inner layer comprising a fast burning propellant composition having a higher linear burn rate than said slow burning propellant composition; wherein said propellant grain has a structure such that after ignition, the inner layer becomes increasingly exposed at the outer surface.

摘要： Methods of making and resultant compositions thereof, which include a gas generant having a coating including an inorganic combustion inhibitor. Such coated gas generants are useful in pyrotechnic compositions and ignition materials, and may be employed, for example, in inflatable restraint systems. The ratio of coated and uncoated gas generant bodies within an airbag inflator may be tailored to provide S-curve inflation performance. Spray application of aqueous mixture including the combustion inhibitor onto the gas generant body provides a rapid way to achieve a thin but robust coating.

摘要： Techniques and processes that combine particulate coating processes with particulate handling steps resulting in the formation of free-flowing particulates for introduction into energetic product vessels to affect an in-situ, net-shape manufactured product. The processes involve selecting suitably sized materials, processing such materials such that they are surface-coated and/or locally “structured” particulates, and pouring, preferably “dry” pouring, these processed materials into an energetic product vessel and infusing the filled vessel with a polymerizable and surface-compatible monomer or oligomer which flows into the unoccupied volume, followed by polymerization of the monomer, which then becomes the binder giving mechanical integrity to the final, net-shape energetic composition.
