  • Patent number: 9506188
    Abstract: A hybrid rope constructed of a plurality of strands, wherein each strand is constructed of a fiber center, a jacket surrounding the fiber center, and a plurality of wires surrounding the jacket. The fiber center can be constructed of one or more high-strength synthetic fibers or yarns. The jacket can be constructed of polypropylene, thermoplastic polyurethane, high-density polyethylene, linear low-density polyethylene, nylon or other similar materials. The jacket can have a braided or woven design and adds a protective layer between the fiber center and the wires. The wires can be constructed of high-strength steel wires, galvanized steel or stainless steel. The fibers or yarns that make of the fiber center are twisted to lay right and then covered with the jacket. The wires then surround the jacket and are twisted to lay to the left. This creates a torque-balanced condition of the hybrid rope.

    Abstract: Cut-resistant yarn suitable for machine knitting and machine-knitted protective articles of apparel, more specifically flexible gloves, at least in part made from such a yarn and also such gloves having a slip-resistant coating, preferably polyurethane, applied in a predetermined pattern to the outside surface of the gloves. The yarn utilizes a core of synthetic fibers held in a bundle by two initial wraps of low denier synthetic material having widely spaced turns or by a plastic coating on, or by a plastic matrix for, the fibers. One or more strands of metal wire or glass fiber are disposed about the core. The initial wraps or plastic that bundle the core create a uniform, cylindrical shape to the multi-filament fiber core that is believed to increase cut-resistance and that promotes uniformity in yarn diameter as subsequent wraps are applied, and prevent sharp bends in the wire or glass fibers disposed about the core. Additional wraps cover the wire or glass fiber.

    Abstract: Multi-strand superconducting cables adapted to be used, for example, to wind a magnet is fabricated by directing wire strands inwardly from spools disposed on the perimeter of a rotating disk and wrapping them diagonally around a tapered mandrel with a flattened cross-sectional shape with a core having a wedge-shaped channel. As the cable is pulled axially, flexibly coupled wedge-shaped pieces are continuously passed through the channel in the mandrel and inserted into the cable as an internal support therefor.

  • Patent number: 4501115
    Abstract: A wire rope for use in a traction type elevator system is coated with a soft-solid agent or a greasy agent having a drip temperature higher than 55.degree. C. and exhibiting physical properties such that it is evaporated in an amount less than 1 weight percent at 105.degree. C. for an interval of eight hours and elevates the coefficient of friction or traction between the wire rope and the drive sheave when coated on the wire rope.

  • Patent number: 4313998
    Abstract: The invention relates to a new complex filiform textile element comprising fibers of an inorganic material.The element in accordance with the invention is characterized by the fact that the fibers are contained on the outside by an enveloping but open structure of metal, the total area of the openings (So) being greater than the total area of the enveloping structure (Se) covering the apparent peripheral surface of all the entire fibers.

  • Patent number: 4217748
    Abstract: Steel wire rope used for lifting and hauling is dangerous when stressed above the breaking point, as there is a substantial quantity of energy stored in the stretched rope and when the rope breaks the stored energy causes the broken ends to whip at high velocity, in a number of recorded cases causing fatalities, and serious damage to helicopters, cranes, vessels and vehicles. This invention discloses a steel wire rope with a strong hand elastic sleeve or sleeves which are not in longitudinal tension, and which dissipate by friction the energy stored in the broken cable, thus materially reducing the possibility of damage to the surroundings.
