Abstract:
A reinforcement for a building works structure comprising an assembly of solid wires. The wires are mutually parallel to form a bundle and the reinforcement comprises a sheath made of plastic material enclosing the bundle and providing it with cohesion.
Abstract:
An extruded polymeric rod is elongated in the solid state by being drawn through a forming device to produce a solid polymeric core having an orientated structure which comprises elongated crystals orientated in the axial direction of the core. The core may also comprise crystals orientated in respective radial directions. The single rod may be replaced by a bundle of rods.
Abstract:
This invention provides a composite wire rope comprising a plurality of outer strands laid helically about a helically stranded core. The core is comprised of high strength synthetics, such as polyamide or polyolefin materials to form a unitized lay central member. The method for forming the rope comprises the steps of twisting high strength synthetic monofilament yarns into core elements to provide a high degree of stability and overall tensile strength. Each such element is helically laid in a single operation to form the finished core. Lubricant may be applied and subsequently a protective jacket of steel, natural or synthetic material may be provided to encapsulate the core and lubricant. The rope structure is completed by helically laying a plurality of outer strands about the core.
Abstract:
A FLEXIBLE, LOAD-BEARING STRAPPING ARTICLE WHICH CONSISTS ESSENTIALLY OF AN INTERTWINED STRUCTURE OF CONTINUOUS MULTIFILAMENT YARNS OF A FIBROUS POLYAMIDE, E.G. NYLON 6 (POLYCAPROLACTAM) OR NYLON 6,6 (POLYHEXAMETHYLENE ADIPAMIDE), WHICH HAS BEEN REINFORCED WITH AN ELASTOMERIC COPOLYMER OF BUTADIENE, STYRENE, ACRYLONITRILE AND METH-
ACRYLIC ACID-. THE ARTICLE IS PRODUCED BY IMPREGNATING AND SURFACE-COATING THE INTERTWINED YARN STRUCTURE WITH AN AQUEOUS EMULSION OF THE COPOLYMER AND THEN HEATING TO CROSS-LINK THE COPOLYMER ONTO THE YARN.
Abstract:
A jacket for a load-bearing, lengthy body, wherein the jacket is comprised of a plurality of braid elements which, when braided, enclose at least a portion of the lengthy body, and wherein the braid element is comprised of a braided ribbon. A method of forming the jacket is also described.
Abstract:
A cable 1 comprises a first thimble 2 and a second thimble 4, at least one yarn 6, and at least a first conductive fiber 8 for monitoring the cable 1. The yarn 6 extends from the first thimble 2 to the second thimble 4, turns around the second thimble 4, extends from the second thimble 4 to the first thimble 2, and turns around the first thimble 2. Each thimble holds a stack 9 of layers 10 of turns of the yarn 6. The first conductive fiber 8 is designed to signal the wear of the yarn 6 by breaking after a predetermined portion of the turns of the yarn 6 breaks. The first conductive fiber 8 is positioned at the first thimble 2 between the turns of the yarn 6 at less than 50% of the stack height h.
Abstract:
A method for producing a strand or cable, in which fibers and/or wires are twisted at a twisting point to form the strand or cable. The fibers and/or wires are coated with a liquefied matrix material before and/or at the twisting point and are embedded in the matrix material during twisting. The fibers and/or wires are immersed in the matrix material before and/or at the twisting point and the formed strand or the formed cable is cooled after the twisting in order for the matrix material to solidify, preferably by air or in a cooling liquid, for example water.
