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 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： This invention relates to a thermite reaction charge comprising bismuth oxide and aluminium adapted to react with a reaction rate giving a reaction time of 8 to 15 seconds for a thermite reaction charge of 30 to 100 kg from initialisation of the thermite reaction charge to at least 90% of the thermite reaction charge is reacted, a method for forming a three-phased rock-to-rock barrier by applying the thermite reaction charge and a well barrier formed thereof.

摘要： A propellant in the form of a pellet includes adjoining pellet sections. Each pellet section includes a smokeless powder, a burnable metal, and a polymer. The smokeless powder in each pellet section will in many examples be different from the burn rate of the smokeless powder in other pellet sections. A nonignitable tube passes through the center of the pellet. When the pellet is used within a firearm cartridge, the ignition products from the primer travel through the nonburnable tube, igniting the pellet sections sequentially from the front to the rear of the cartridge. The pressure generated by the propellant within a cartridge casing can be maximized and controlled through the selection of the burn rate for each pellet section.

摘要： Solid propellant systems include a main propellant and a secondary propellant in contact with the first propellant that exhibits autoignition temperatures of at least about 100° F. lower than the autoignition temperature of the main propellant. The secondary propellant of the present invention is most advantageously employed with conventional AP-containing solid propellant formulations as the main propellant, especially formulations containing both AP, an energetic solid, and a binder. In especially preferred forms, the secondary propellant will include a nitramine which is at least one selected from nitroguanidine (NQ), cyclotrimethylene trinitramine (RDX) and cyclotetramethylenetetranitramine (HMX), and a binder which is at least one selected from HTPB, HTPE or glycidyl azide polymer (GAP). Most preferably, the secondary propellant will include a combination of nitramines which includes NQ and one of RDX or HMX.

摘要： A munition, such as a projectile formed of at least one reactive material. In one embodiment, the projectile includes a body portion formed of at least one reactive material composition wherein the at least one reactive material composition defines at least a portion of an exterior surface of the projectile. In other words, a portion of the reactive material may be left “unbuffered” or exposed to the barrel of a gun or weapon from which it is launched and similarly exposed to a target with which the projectile subsequently impacts. In one embodiment, the projectile may be formed with a jacket surrounding a portion of the reactive material to provide additional structural integrity. The projectile may be formed by casting or pressing the reactive material into a desired shape, or the reactive material may be extruded into a near-net shape and then machined into the desired shape.

摘要： The propulsion system for the acceleration of projectiles is based on a multi-perforated grain propellant and is composed from nitrocellulose, a crystalline energy carrier of a nitramine type and an inert plasticizing additive. The number of perforations is 2 to 6, preferably 4. The propellant grains can have round or polygonic profiles, depending on the number of perforations. The preferred grain geometry is cubic with a rectangular grain profile. The nitramine compound contains a structural element of the general chemical structure formula R—N—NO2, where R is a residual group. The nitramine compound is present in a concentration in the range from 0 to 35% by mass, in particular in the range from 5 to 25% by mass. The nitramine compound is preferably RDX. The inert plasticizing additive is a water-insoluble polyoxo compound, if necessary in combination with a substance containing carboxyl groups. In layers near the surface an increased concentration can be present. The inert plasticizing additive is present in a concentration of 0 to 10% by mass, preferred 0 to 5% by mass.

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.
