Abstract: A waterproof shielded cable is disclosed having a metallic shield formed with a longitudinal seam surrounding a core. A strip of material overlays the metallic shield seam with side edges located to each side of the seam. An extruded plastic jacket overlays the metallic shield and strip of material with the jacket being in intimate contact with the shield and with a principle surface of the strip of material but spaced from the strip side edges.A method is also disclosed for manufacturing a shielded cable which comprises the step of wrapping sheet metal about a cable core with the sheet metal edges overlapped to form a shield with a longitudinal seam. The shield seam is overlayed with a strip of material of a type characterized by being shrinkable when heated above a predetermined temperature, and with the strip edges straddling the shield seam. A plastic jacket is extruded onto the shielded core and strip of material at a temperature in excess of the predetermined temperature.

Abstract: A generally planar fabric having a plurality of solid colored stripes. The fabric comprises a first plurality of warp yarns having a first color, a second plurality of warp yarns having a second color different from said first color, and a plurality of transparent filling yarns. All of the yarns are interwoven according to a desired weave pattern. At the yarn crossover points or junctions of the fabric, the transparent yarns allow the colors of the warp yarns to show through. In a preferred embodiment, a multifilament core yarn encapsulated in a plastisol containing a foaming agent constitutes the warp yarns, and a multifilament transparent core yarn encapsulated in a clear plastisol constitutes the filling yarns.

Abstract: The method of autogenously bonding a nonwoven web made from polyamide filaments wherein the filaments contain 0.1 to 20 weight percent of an activating agent and sufficient moisture that the molar ratio of water to activating agent in the filaments is above the bonding limit, wherein the web is heated sufficiently to drive off enough water to reduce the molar ratio of water to agent to a value below the bonding limit and pressed to autogenously bond the filaments in the web. After pressing, the activating agent is desorbed from the web.

The casing is formed from the heat-foamable synthetic resin.

Abstract: A fabric sleeve having lengthwise yarns of a low friction material and circumferential threads of a bondable material is secured on a mandrel utilizing in particular the heat shrinkage of the circumferential threads but also the axial shrinkage of the low friction material. After cooling, the sleeve is impregnated with a liquid resin and may be stored for future use utilizing the ends of the mandrel for support and handling. When required, the resin is cured to form a rigid tube. The tube has an internal bearing surface a predetermined size larger than the mandrel and may be readily withdrawn from the tube and then cut to selected lengths to comprise the desired bearings.

Abstract: Fibrous carbon material such as graphite cloth which is to be combined with a thermosetting resin and a boron containing compound to form a carbon-carbon composite is provided with a protective coating consisting of cured furfuryl alcohol copolymers. When formed into a laminate and heated to at least 2150.degree. C. to carbonize and at least partially graphitize the thermosetting resin, the boron greatly increases the interlaminar tensile strength while the coating protects the fibrous material from adverse effects of the boron which reduce the tensile strength in the directions of the fibers of the fibrous carbon material of the composite.

Abstract: A finishing welt, comprised of a reinforcing polyethylene rod surrounded by a fabric scrim and an outer encasing layer of polyvinyl chloride, is formed in an extrusion-embossment method and apparatus.The method includes feeding a composite preform, consisting of the polyethylene rod and the scrim, first through an essentially key-hole shaped passageway in a core pin of an extruder crosshead and then into a chamber within the crosshead where plastic material under pressure flows onto the preform. Immediately thereafter, the preform is conveyed through an essentially key-hole shaped orifice, where the welt is formed by extrusion. Next, the opposed sides of the welt are sequentially embossed as the welt is conveyed over external peripheral embossing surfaces of two spaced rollers.The resultant welt is essentially key-hole shaped in cross-section, with the scrim surrounding the rod within the enlarged head portion of the welt and extending into the smaller depending flange portion.

Abstract: A base fabric for a radar defeating camouflage material comprising a knitted fabric knitted from a plurality of strands to form a stretchable, flexible fabric having a plurality of openings therethrough, each of these strands constituting a spun mixture of noncontinuous polymeric fibers and noncontinuous metal or carbon fibers. The fibers can be nylon or polyester. The metal fibers can be stainless steel. The metal or carbon fibers can comprise about 2 - 10 percent by weight of the spun yarn, the fibers having an average diameter between about 0.008 and 0.02 millimeters and an average length between about 50 millimeters and 90 millimeters.

Abstract: This invention relates to man-made fibres particularly adapted for use in yarns and household fabrics, that is fabrics for end use in dresses, blouses, head shawls, shirts and so on.The man-made fibre of this invention displays a complex cross-sectional shape formed of two elements, each of these elements comprising three rays outgoing from a single point, two adjacent rays making up an angle of 10.degree. to 70.degree. and free ends of middle rays being interconnected by a flexible bridge. Such a man-made fibre contributes appreciably to moisture conductivity and moisture absorption in yarns and textiles produced from this fibre, making their moisture conductivity and moisture absorption approximate those of natural silk textiles.

Abstract: Normally flammable fabrics, such as fabrics composed of polypropylene and polyamides such as polycaproamides, poly(m-phenyleneisophthalamides) and the like which have been rendered flame proof by the intimate association therewith of a flame proofing amount of a phosphoric acid are reacted in situ with an epoxy compound. The resultant compositions can be washed in water without substantial loss of flame proof character.

Abstract: Antimicrobial properties are imparted to naturally occurring fibers, such as cotton fibers and fabrics, by intimately admixing the naturally occurring fibers with synthetic fibers prepared by extruding a spinnable solution of a synthetic thermoplastic resin and at least 0.1% by weight of an antimicrobial agent into a strand having a denier of 1.5-60 dpf. The synthetic fibers are characterized by the antimicrobial agent therein migrating to the fiber surface to form a coating thereon and then transferring to the naturally occurring fibers by physical contact as the amount of antimicrobial agent on the surface of the naturally occurring fibers diminishes. Additional antimicrobial agent then migrates to the surface of the synthetic fiber until equilibrium is re-established.

Abstract: A fibrous article having a suede-like surface is composed of numerous staple fiber bundle units mutually entangled with one another in a three-dimensional configuration. Each staple fiber bundle unit comprises a plurality of flexible and relatively movable synthetic organic ultrafine fibers having a substantially round cross-sectional profile, substantially the same fiber length, and lying axially along the longitudinal axis of the staple fiber bundle unit. Elastic bonding material is disposed around and spaced axially along the ultrafine fiber bundle units joining together adjacent ones of the ultrafine fiber bundle units at locations where they intersect with one another to jointly hold the entangled ultrafine fiber bundle units in their three-dimensional configuration while permitting slight relative longitudinal movement between the individual ultrafine fibers within each ultrafine fiber bundle unit.
