    摘要： An air bag inflator for an automobile includes an elongated, tubular housing (18) having a plurality of perforations (19) in its cylindrical wall for discharging gas. Within the housing are a gas generant composition, an igniter and filtering screens. The perforations are normally sealed with non-tempered aluminium foil (46) which is easily ruptured by 'the gas pressure when the inflator is ignited and which, in addition to serving as a hermetic seal for protecting the gas generant and igniter from moisture and dust, insures that the gas pressure will reach a certain, threshold level before being discharged into an air bag. In very cold weather the inflator attains its peak pressure considerably more slowly than in warm weather. As a result, the air bag may be inflated either too slowly or insufficiently to perform its intended purpose, In order to preclude this from happening at least some of the perforations (19) in the housing (18) are covered with an additional or buttressing layer of thicker non-tempered aluminium foil (86), so that the threshold gas pressure necessary to rupture these seals is raised. This shortens the time for attaining peak gas pressure within the tubular housing and results in faster, more satisfactory inflation of the air bag when the ambient temperature is low.

    摘要： An infrared decoy flare (10) having enhanced infrared intensity is disclosed. The flare includes a case (12) in which an infrared illuminant composition (14) is disposed. The bore diameter and length of the case are advantageously selected to be compatible with preexisting chaff dispensers and their cartridges located on aircraft. The illuminant composition, the nozzle throat area, the geometry of the illuminant composition, and the volume of the combustion chamber are selected such that combustion of the illuminant composition results in an unstable combustion condition during the first second of combustion, thereby increasing the peak intensity of the radiation emitted by the propellant. Preferably, the flare is configured such that the unstable combustion occurs during the first 0.2 to 0.5 seconds of combustion of the illuminant composition.

    摘要： Chemorheologically viscosity tailored matrix resin formulations for use in forming prepregs and composite articles are disclosed. These formulations have a specified viscosity profile obtained from a curable matrix resin and an effective amount of a reactive resin curing agent reactive at room temperature and a latent resin curing agent substantially nonreactive at room temperature. The latent resin curing agent is activated upon heating or radiation. The matrix resin formulation is adapted upon formulation to have a viscosity sufficiently low enough to enable the matrix resin to impregnate fibers or broadgoods at room temperature without the necessity for the application of heat or solvent and which, upon standing at room temperature after impregnation into the fibers or broadgoods to form a prepreg composition, rises in viscosity. The matrix resin in the prepreg experiences a reduction in viscosity upon heating to a viscosity minimum sufficiently low to allow the matrix resin to flow and substantially eliminate formation of voids in the composite article from said prepreg yet not so low as to permit excessive bleeding of the matrix resin from the prepreg. With continued heating, the matrix resin in the composite article cures to a hardened or gelled state.

    摘要： A continuous extrusion process for manufacturing composite gun propellant is disclosed. The disclosed process is particularly suitable for preparing gun propellant formulations based upon a cellulose ester binder. In the process, the binder ingredients are dissolved in an organic solvent and then pumped directly into a twin-screw extruder. The other ingredients, except the oxidizer, may optionally be dissolved in the organic solvent prior to introduction into the twin-screw extruder. The oxidizer is dried, ground, and also fed dry to the twin-screw extruder. In the extruder, the materials are thoroughly mixed and the solvent is reduced to sufficient level for direct extrusion through the desired dies.

    摘要： A sodium-azide-free gas-generating composition includes an oxidizable inorganic fuel, such as a metal, and an oxidizing agent containing oxygen and a metal. The fuel and the oxidizing agent are selected such that water vapor is produced upon reaction between the inorganic fuel and the oxidizing agent. Although a number of inorganic fuels can be employed, a suitable fuel can be a transition metal, another element such as silicon, boron, aluminum, magnesium, and intermetallic compound, hydrides of these metals and mixtures thereof. Suitable oxidizing agents are selected from basic metal carbonates and basic metal nitrates. The fuel and oxidizing agent are selected such that substantially nontoxic gases are produced such as mixtures of water vapor and either carbon dioxide or nitrogen.
