    摘要： A tool for driving a nail or other fastener is actuated by a caseless propellant charge formed of combustible material that is transported into a combustion chamber on a strip. The propellant charge is ignited by striking a sensitizer portion of the charge at an oblique angle. The ignition member intermixes the sensitizer material with an oxidizer layer of the surface of the propellant charge, resulting in combustion of the charge. When ignited, the propellant charge is compressingly interposed between an orifice plate and a movable portion of the combustion chamber. The orifice plate includes a pedestal with an annular compression surface that separates the surface of the ignition area from the remaining surfaces of the charge, insuring that ignition gases are forced through the charge. An annular C-shaped ring is interposed between the orifice plate and the movable portion of the combustion chamber. When the charge is ignited, the resulting gas pressure resiliently expands the annular C-shaped ring and urges opposite axial ends of the C-shaped ring into sealing relationship between the relatively movable components of the combustion chamber. Combustion gases are communicated through orifices in the orifice plate to a cylinder where the gases force movement of a driver, which driver strikes and drives a fastener such a nail. The driver is reciprocally movable within the cylinder and is returned to its precombustion position by a gas spring return cylinder. The gas return cylinder in mechanically interconnected to the driver and contains a sealed gaseous fluid that is independent of and segregated from fluids in the combustion chamber. An assembly for deaccelerating the driver includes a series of spaced and aligned progressively sized metal cup members of progressively increasing mass, contact surface and interface angles.

    摘要： A method for providing chemical energy and energetic compositions of matter consisting of thin layers of substances which will exothermically react with one another. The layers of reactive substances are separated by thin layers of a buffer material which prevents the reactions from taking place until the desired time. The reactions are triggered by an external agent, such as mechanical stress or an electric spark. The compositions are known as metastable interstitial composites (MICs). This class of compositions includes materials which have not previously been capable of use as energetic materials. The speed and products of the reactions can be varied to suit the application.

    摘要： The invention relates to a low-vulnerability explosive munitions element comprising a casing containing a multicomposition explosive charge, the innermost layer of which is a composite explosive comprising a filled polyurethane or polyester polymer matrix, the filling of which contains more than 40% by weight of organic nitrate explosive, and the peripheral layer of which is a pyrotechnic composition of the family of composite solid propellants comprising a filled polyurethane or polyester polymer matrix the filling of which contains at least one mineral oxidant and less than 10% by weight of organic nitrate explosive. The blast and/or bubble effect produced is close to that produced by the much more-vulnerable charge of monocomposition composite explosive of equivalent mass. The invention also relates to a method for obtaining a blast and/or bubble effect by releasing in the casing of an aforementioned munitions element according to the invention, and then rupture of the casing. The release of gas is obtained by detonation of the innermost layer and then reaction without detonation of the peripheral layer.

    摘要： Pyrophorically activated aluminides of iron, nickel and cobalt, or mixtures thereof, are formed as discs or as coatings on substrates such as thin foils. The aluminide can be formed in situ by reacting aluminum powder with the aluminide-forming metal. Mixtures of these reactants can be applied to a substrate as such or suspended in a liquid like water or volatilizable organic liquids. Water is preferably used with a little binder such as an alkali metal silicate. An inhibitor is used to keep the water from reacting with finely-divided aluminum, and those silicates also perform such function. The pyrophoric products can be discharged to decoy heat-seeking missiles, or they can have their pyrophoricity destroyed to make catalysts. Pyrophoric action can be heightened by additives such as boron, and by post treatment with mild acid.

    摘要： Metals are made pyrophoric by diffusing aluminum or zinc into them and then leaching it out, or by reacting with aluminum and then leaching aluminum out. Powdered aluminum and powdered nickel, iron or cobalt, can thus be carried on an elongated support web and reacted by heating for a few seconds to a few minutes, after which leaching will provide elongated pyrophoric foil suitable for decoying heat-seeking missile.
