Abstract: A quick-release buckle assembly including an engaging member that is adap to receive a strap, and a receiving member defining a recess for removably receiving the engaging member in a buckle-engaged position. The engaging member in the buckle-engaged position is substantially completely within the peripheral bounds of the recess to prevent inadvertent disengagement of the engaging member from the receiving member. The assembly further includes a flexible tongue protruding from the engaging member to allow the engaging member to be pulled out of the recess to disengage the buckle.

Abstract: A helmet suitable for use by combat vehicle crewmen comprises a rigid she formed of a ballistic resistant material, having earcup receiving extensions affixed thereto. Earcups are mounted in the shell extensions and are capable of movement in two directions relative thereto. The helmet also has an internal suspension system which affords two additional size adjustments.

Abstract: A method of making a deep drawn, laminated, non-metallic article having h ballistic resistance and having a smooth edge which comprises, preparing a preform comprising a plurality of superimposed patterns of aromatic polyamide fabric impregnated with a thermoplastic or thermosetting resin, then either (a) trimming the preform to form a peripheral edge thereon so as to allow for application of additional resin in a suitable form to the peripheral edge during the final molding of the preform, applying the additional resin to the peripheral edge of the trimmed preform, and finish molding the article accompanied by flow of the additional resin about the peripheral edge to produce a smooth edge on the final molded article, or (b) applying an epoxy resin film on the outer surface of the preform, or on the superimposed patterns prior to making the preform, around the periphery of the preform or superimposed patterns and overlapping the line around the periphery of the preform on which cutoff occurs in the finish mol

Abstract: An apparatus for the measurement and numerical description of three-dimennal objects, such as human heads. The apparatus comprises a hollow hemisphere having a plurality of probes which can be moved toward or away from a three-dimensional object held in place within the hollow hemisphere. The probes are movable in sleeves which pass through the wall of the hemisphere, enabling the measurement of distances between the hemisphere and the three-dimensional object at various points on the outer surface thereof.
