Abstract: An efficient direct functionalization of nitrocubanes has been achieved by irradiation of a solution in an oxalyl halide to yield halogenated and halocarbonylated derivatives of nitrocubanes.

Abstract: A low cost warning system for armored vehicles which uses multiple sensors ontaining detectors for IR and millimeter wave signals emanated by attacking missiles and/or projectiles to allow the launching of screening grenades. The sensors telemeter their coded signals to a receiver inside the vehicle which process the coded signals to direct the exercise of an active screening defense.

Abstract: A method for measuring the azimuth angles of grenade launcher tubes quickly nd directly, uses an easily fabricated, portable fixture and a commercially available hand-held electronic compass. There is not need for a precise set-up of complex equipment or mathematical computations.

Abstract: The velocity of a fluid in a positive or negative direction is measured by se of a thermistor in a feedback circuit. The temperature of a flow thermistor is balanced with the temperature of a reference thermistor by sensing temperature through resistance by way of its voltage and adding power until the flow thermistor is at the same temperature as the reference thermistor. The ratio of reference power used as compared to flow power is indicative of the fluid's speed. Power is added by sending a signal of varying frequency to the flow thermistor; the reference thermistor is powered by a constant frequency signal. Power is measured by comparing the frequencies of the reference signal to the flow signal. Fluid direction is measured by placing a direction thermistor on either side of the flow thermistor, measuring the temperature of each direction thermistor, the cooler thermistor being upstream of the flow thermistor.

Abstract: The invention provides a continuous moving bed reactor, useful for the prration of 3,7-diacetyl-1,3,5,7-tetraazabicyclo-3.3.1-nonane (DAPT). The reactor makes novel use of water, a known catalyst for said reaction. However, in this invention, the water is present as ice. The ice is made to automatically promote and moderate the reaction as well as regulate the flow of hexamine into the reactor. These automatic functions are achieved by mixing ice with hexamine, the latter is one of two principle reactants used, to generate a standing bed of slurry. When melted at its base, the slurry advanced under the influence of gravity. The melting of the ice being caused by local application of the second principle reactant, acetic anhydride, which is a liquid.The apparatus is constructed in the following way. A tube shaped reservoir for containing the cited slurry is open at the top end and terminates at its bottom end by a porous compartment. The latter compartment openly retains the slurry. A fluid delivery device, i.

Abstract: 2,2,4,4,6,6-hexamitroadamantane and a method of making the same.

Abstract: The present invention is directed to an apparatus intended to allow detonon of munitions by the occurrence of a triggering event at a location remote from the actual munition. This apparatus contains a piezoelectric crystal which is deformed by the firing of a conventional blasting cap upon the happening of a triggering event. Deformation of the piezoelectric crystal generates an electric impulse sufficient to initiate an electric blasting cap thereby detonating the munition.

Abstract: A method of casting high melting point metal such as refractory metals into ngots to provide substantially improved strength and density. A quantity of high melting point metal is placed in an arc area of a furnace having a "T" shaped vacuum chamber with a pair of opposing electrodes which generate an arc to cause droplets of the metal to melt from the heat thereby generated. The droplets fall into a mold positioned to receive the droplets and shaped to form the desired ingot. The method includes an additional step of further heating the droplets as they fall into the mold with a plasma arc gun mounted inside the furnace. The gun is directed to impinge its heat torch to control the rate of solidification such that a small pool of the liquid phase is maintained on the ingot. The last step comprises solidifying the molten metal in the ingot by controlling the plasma arc gun and the heat generated from it.

Abstract: A method for making uranium-tungsten alloy of high strength comprising raly chilling a molten solution of tungsten in uranium to form a ribbon. Subsequent to pulverizing and consolidation, heating effects a precipitation of tungsten in the uranium to effect significant strengthening. A strengthened uranium with 1/2-5%, by weight of tungsten is particularly useful for KE penetrators.

Abstract: This invention describes a process for producing copper alloys by rapid sdification in order to improve their strength and thermal stability after being exposed to elevated temperatures. The method used to rapidly solidify the molten alloy is either by use of a high pressure non-oxidizing gas spray to atomize the molten alloy into a powder or to pour the molten alloy onto a rotating wheel to form a ribbon which is then attrited into powder. The powder is canned, compacted to full density and cold worked to the desired shape.

Abstract: A mixture containing 3,3-bis(aziodomethyloxetane) and o-chlorobenzyl maloitrile for use as a riot-control gas.

Abstract: Heat is used to decontaminate toxic agents from the interior contaminated rfaces of combat vehicles and like enclosures. The heat vaporizes the toxic agents, but does not cause heat damage to the interior contaminated surfaces themselves. Hoses are used to convey the heat to the toxic agent to vaporize the same, as well as to remove the vaporized toxic agent away from the interior contaminated surface for discharge outside the enclosure.

This apparatus ludes a hopper having a space for fluidizing a selective powder, an inlet jet nozzle extending through the hopper into the space, an outlet passage extending through the hopper and surrounding the inlet jet nozzle, spray means connecting to the outlet passage, and a compressed air source connecting to the jet nozzle.

Abstract: A minimum hazard visual screening cloud is formed by vaporizing diesel fuel nside a vehicle exhaust manifold pipe which, upon entering the ambient atmosphere, condenses into an aerosol comprised of small droplets, thereby producing a large sustaining cloud which obscures both the vehicle and the adjacent downwind areas.

Abstract: A NBC hardened double shot grenade launcher utilizes a latching relay and delays to sequentially activate two secondary relays. The delays keep the latching relay from operating until a relay switch transfers supply voltage to enable firing of double the number of salvos without modification of the original supply line.

Abstract: A lightweight linear shaped charge for explosive cutting and penetration of target, which includes a plastic linear housing in the form of a concave channel with an inverted "V" shaped metallic liner mounted within the concave channel. An explosive charge is shaped and held between the plastic housing and the metallic liner. Upon detonation of the explosive charge an explosive jet of the metallic liner is generated to cut and penetrate the target. Also, the plastic linear housing may be extended downward a short standoff distance of approximately 0.5 to 1 inch for optimum cutting and penetration of the target.
