Abstract: The invention is a new heat and fire resistant material and an improved wildland fire shelter and kit. The material is made of a woven silica-based cloth layered in several possible combinations with foil and fiberglass cloth layers. The layers can be arranged in a variety of sequences to minimize the thermal radiation to the inside of the material or shelter. However, a foil layer must always be the outermost layer to provide protection from radiant heat and a layer of foil must be present between the interior of the shelter or material and any layer of adhesive to limit accumulation of gases inside the shelter if the adhesive or other substance should break down when exposed to heat. The silica cloth, aluminum foil, and fiberglass cloth may be laminated or sewn together. The shape of the fire shelter is a half cylinder with ¼ sphere at each end. The shelter is contained in an easy-open polyvinyl bag which provides for quick removal and deployment of the fire shelter.

Abstract: The present invention relates to a process for producing a woven textile-elastomer composite that, when transfer or film-coated, is suitable for use as an artificial leather substrate. The inventive procedure involves (a) producing an elastomer composition of at least four ingredients (an anionically-stabilized waterborne polymer dispersion, an acid-generating chemical, a cloud-point surfactant, and a foam-stabilizing surfactant); (b) incorporating sufficient gas into the liquid mixture to generate a spreadable foam; (c) applying the foam onto a porous woven textile substrate; (d) heating said foamed fabric until the elastomer coagulates over the fabric substrate; and (e) drying the resultant composite without destroying the coagulated structure. The resultant composite obtains a pliability, compressibility, and drape that is similar to that of leather and a surface that is suitable for transfer or film-coating to produce artificial leather.

Abstract: Thermoplastic welding is an emerging technology targeted at significantly reducing the manufacture of aerospace structure by eliminating fasteners and the touch labor associated with fasteners to prepare, install, and inspect the assemblies. Thermoplastic welds, however, suffer from significant residual tensile strain caused by differences in the coefficient of thermal expansion between the carbon fiber reinforced composite laminates and the unreinforced weld. We alleviate this strain by adding fiber reinforcement to the weld using a structural susceptor which is a laminate of alternating layers of thermoplastic resin and fiber reinforcement sandwiching a conventional metal susceptor. A further advantage of the structural susceptor is the ability to peel it in selected locations to fill the gap between the laminates, eliminating costly profilometry of the faying surfaces and the associated problem of resin depletion where machining occurred to match the faying surfaces.

Abstract: A dimensionally stable core for use in high density chip packages is provided. The stable core is a metal core, preferably copper, having clearances formed therein. Dielectric layers are provided concurrently on top and bottom surfaces of the metal core. Metal cap layers are provided concurrently on top surfaces of the dielectric layers. Blind or through vias are then drilled through the metal cap layers and extend into the dielectric layers and clearances formed in the metal core. If an isolated metal core is provided then the vias do not extend through the clearances in the copper core. The stable core reduces material movement of the substrate and achieves uniform shrinkage from substrate to substrate during lamination processing of the chip packages. This allows each substrate to perform the same. Additionally, a plurality of chip packages having the dimensionally stable core can be bonded together to obtain a high density chip package.

Abstract: A reflecting warp-knit slide fastener tape is knitted with several kinds of knitting patterns. A marginal portion onto which fastener elements are attached extends along one longitudinal edge of the tape. The marginal portion is formed by tricot-stitch yarns, weft-inlaid yarns, and chain-stitch yarns which prevent the marginal portion from stretching.

The reflective members are sandwiched between the weft-inlaid and tricot-stitch yarns. The tricot-stitch yarns are transparent synthetic fiber yarns in order not to obstruct the reflecting feature of the reflective members.
