Abstract: A small arms projectile containing a series of vents or apertures in a geometric arrangement such that the projectile's leading edge is capable of penetrating the target without structural failure and depositing the majority of its residual energy in the target. In addition, the design of the body allows the projectile to be spin stabilized when fired from any suitable weapon.

Abstract: An improved process of making a highly impact insensitive form of HMX cal Alpha HMX has been accomplished. Test results of insensitive impact from drop heights of 5 to 10 times greater than Beta HMX, the conventional explosive, has been successfully achieved. This accomplishment has been achieved without the addition of any additives, and is attributed to the attainment of small particle size, whole crystals, narrow size distribution, and sample purity.

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: A device for swabbing artillery cannon chambers, obturators and the like. e device includes a cylinder for holding a fluid such as water and also has a gas pressure source such as a hand operated air pump for placing the fluid in the cylinder under a positive pressure. The gas pressure or air pressure is adjustably controllable. Also included is a tube extension in communication with the cylinder to receive the fluid under slight pressure. The tube extension includes a valve for controllably introducing water under pressure into the tube extension. A sponge is mounted on the other end of the tube so as to absorb water through the tube to wet the sponge. The device is controlled with a handle on the cylinder to permit insertion and removal of the sponge into a cannon chamber while the sponge contains some of the fluid. The hand operable pump is axially centered about the axis of the cylinder for adding air pressure in the cylinder.

Abstract: A system for remotely detecting liquid contaminants on surfaces, including hemical agents and their simulants is presented. The system includes a Fourier Transform Infrared Spectroradiometer aligned to optionally develop graybody photoluminescence spectra from the generation of a plurality of interferograms co-added to provide a favorable signal to noise ratio for use with and thereafter transforming the co-added interferograms. A laser is used for surface irradiating a substrate potentially having the chemical agents to heat the substrate. A shutter controls the laser to receive and record photoluminescence emissions from the heated substrate, and generate a plurality of interferograms co-added to provide a favorable signal to noise ratio for use with the Fourier Transform Infrared Spectroradiometer. The co-added interferograms are used to generate molecular absorption resonant peaks which are mathematically processed in the Fourier Transform Infrared Spectroradiometer.

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

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 quick disconnect coupling device formed from a female coupling portion a male portion for mating therewith. The outside diameter of the male portion is equal to the inside diameter of the female portion from the axial outer end of the male coupling to a point less than the total distance of penetration and a reduced outside diameter axially inward thereof. Each coupling portion has a valve to close the portions when they are disconnected. The coupling portions are configured to have a difference between the inside diameter of the female coupling portion and the reduced diameter of the male coupling. The female coupling portion is free to rotate about a point of maximum penetration by the male coupling portion to permit quick disconnection upon application of force to the outer end of either of the coupling portions. The edge of the male coupling portion may be tapered inwardly to assist in the rotation.

Abstract: A low profile chemical biological air filter, comprising a frame having a rst end for attachment to a mask and having an upwardly facing surface defining an inlet for the filter. The frame has a length sufficient to space first and second filters from the inlet to the attachment first end and a width sufficient to enclose the two filters. Its thickness is no greater than that necessary to contain only one of the two filters to minimize the thickness of the frame by placing the two filters side by side. The filters include a HEPA filter for removing particulate material from the air and a Whetlerized charcoal filter bed for secondary filtering of the air. The HEPA filter is supported in the frame at the inlet as is the charcoal filter bed along with a fines filter for protecting from dust which may be dislodged from the charcoal filter bed.

The device includes a body portion defining a straight line path from the primer to the blasting cap. Also included is a moveable slide positioned in the body to block the straight line path and moveable to clear that path. A spring is used to act on the slide to clear the path, and a safety pin holds the slide against the spring until firing is desired. A time delay device such as a liquid annular orifice dashpot delays movement of the slide. A preferred embodiment uses two slides and two springs to first clear the path and second place a blasting cap lead in alignment on the path when the slides clear the path.
