Abstract: A hazard protection suit has a pants section which extends to waist level. A torso section extends upwardly to an upper margin below the wearer's arm pits, and a stowage flap extends outwardly therefrom, to hang down over the torso section and to enclose, by a resilient cord, the upper section of the suit including the sleeves, a hood, and a face mask. The upper body section is retained in a folded compact condition against the wearer's torso in ordinary wear. When needed, the retention member is released and the wearer's hands are extended through looped sleeve cuffs, and zippers are operated to secure the upper body section around the wearer, making a sealed interior space. The wearer's utility belt and gear pouches may remain in place as they are undisturbed by the donning of the upper body section. The face mask is secured along a face encircling zipper.

Abstract: A top sheet and a bottom sheet are connected together by wing members, each having a center segment hinged to the top sheet and to the bottom sheet about parallel axes. Wings protrudes from the center segments and are biased to project out of a plane defined between the hinge axes. In a collapsed condition the top and bottom sheets are close together with the wings distorted from their relaxed positions. In the expanded condition the sheets are spaced apart and the wings return to their relaxed positions projecting out from the center segments and conferring stiffness on the structural member and resisting the return of the member to its collapsed configuration. In storage, the sheets are secured along the edges with an underlying rip cord, and may be rolled. The wings may be formed as part of metal or plastic spring members.

Abstract: A garment with a flexible fabric shell has a pocket or vent opening with a resealable closure such as a zipper, snaps, or hook and loop fasteners, which is operable between a closed position, in which the opening in the shell is closed, and an open position, in which the opening in the shell is revealed. A resilient spring member of springy plastic, composite, metal or other material is mounted to the fabric around the opening, and has two arms which have portions which are displaced vertically from one another when the closure is open, but which are resiliently compressed into a common plane when the closure is sealed. Each time the closure is opened, the spring member urges portions of the shell on either side of the flap apart, to thereby enlarge the area of the opening and permit access or air flow therethrough.

Abstract: A military or police helmet system 20 has a flexible plastic liner 24 mounted to the wearer's head 26 by a strap assembly 28. A ballistic shell 30 with a shallow front wall is fastened to the liner 24 and an eye shield assembly 32 is pivotably mounted to the liner for movement between a deployed position and a retracted position between the shell and the liner. The liner has a rear segment connected to a cap segment, with cut-out slots which allow the liner to apply pressure to the wearer's neck. A chin strap is slidable on two stiff side straps which have curved segments allowing the chin strap to move with the user's jaw. A protective face guard assembly 34 engages with the liner and has openings covered by resilient sheets which permit a marksman feel a rifle stock through the face guard.

Abstract: A routed wire electrical center adapter for coupling electrical components having varying terminal footprints with standard electrical center components having a standard terminal footprint through an adapter element within the electrical center including application specific electrical elements for receiving, on a first element end, electrical terminals of a first footprint, and for receiving, on a second element end opposing the first element end, electrical terminals of a second footprint. The first footprint is selected from a wide range of footprints as specified in an application. The second footprint is a standard footprint across a broad range of electrical center applications.

Abstract: A cryogenic rectification system for the separation of feed air wherein at least some of the feed air is liquefied upstream of the separation columns, all of the liquefied feed air is introduced into a higher pressure column, and then a portion of this liquefied feed air is withdrawn from the higher pressure column and in serial fashion introduced into a lower pressure column.
