Abstract:
This invention teaches a rope that can be electrified. The rope is comprised of an outer sheath and an inner core. The outer sheath includes non-conductive elements braided with one or more conductive elements. The conductive elements are wound in a parallel helical pattern and do not touch each other. The inner core is a braid comprising non-conductive and conductive elements. In both cores, the conductive elements comprise one or more metal strands and the non-conductive elements comprise one or more monofilaments of synthetic or natural fibers. Should a breakage occur in the conductive elements of the outer sheath, the conductive elements of the inner core provide conductivity across the breakage and throughout the length of the rope by intermittently contacting the conductive elements of the outer sheath. An optional colored tracer can be braided into the outer sheath to provide better visibility since the non-conductive elements are preferably a neutral color, such as white.

Abstract:
A binding cord for a motor for an electric vehicle includes a braided round cord of eight or more strands using a multifilament strand made of synthetic fibers having a melting point or a decomposition temperature at 280null C. or more. The binding cord has oil resistance at high temperatures of 50% or more, the oil resistance at high temperatures being represented by the following formula: oil resistance at high temperatures (%)null(Tnull/T)null100. Here, T denotes a tensile strength of the binding cord before treatment and Tnull denotes a tensile strength of the binding cord after the treatment. The tensile strength is measured in accordance with JIS L1013-8.5.1, and the treatment is carried out in such a manner that the entire binding cord is put into a closed container containing a mixture of 5 weight % of water and 95 weight % of automatic transmission fluid, followed by heating the container so that a temperature of the mixture is maintained at 150null C. for 1,000 hours.

A prosthetic ligament includes a cord of thermotropic liquid crystal filaments. The cord preferably comprises multi-filament thermotropic liquid crystal filaments. The cord has an eye spliced at each of its ends.
Abstract:
A high strength abrasion resistant surgical suture material with improved tie down characteristics is color coded for visualization and identification purposes. The suture features a multifilament cover formed of strands of ultra high molecular weight long chain polyethylene braided with polyester, nylon or a bioabsorbable material. Selected nylon fibers in the cover are provided in a color contrasting with the other cover fibers to provide an identifiable trace. The cover surrounds a core formed of twisted strands of ultrahigh molecular weight polyethylene. The suture, provided in a null2 size, has the strength of null5 Ethibond, is ideally suited for most orthopedic procedures, and can be attached to a suture anchor or a curved needle.
Abstract:
A filament rope may be produced continuously by the method and apparatus of this invention. In an upper portion of a frame of the apparatus is a unit having strand carrying spools that move about to braid the strands into a core of the rope. During braiding the strands overlap to form sets of pairs of transversely aligned openings which decrease in size as the rope core is drawn away from the braiding unit by a tension wheel assembly. While the openings are still large, a filament length carried by a first cylinder passes through one pair of strand openings. The cylinder then is withdrawn and the filament length severed leaving a filament segment in that pair of openings. Next, a second filament segment is placed in the other strand opening pair by a second cylinder. After filament segment insertion a tamping tool engages the strands and inserted filament segments to promote opening size reduction and improve formation of a compressive fit by the strands on the filament segments. The filament carrying rope core next may travel through a heating unit that softens the filament segments for crimping by a set of reciprocating rings. As crimped, the filament segments form an array about the core particularly adapted for absorbing liquid wastes.
Abstract:
A slip knot wrist strap attachment for an item of equipment, such as a sport racquet, is fabricated from a single piece of tubular braid. One end of the braid is inserted through the core of the tubular braid from an insertion point thereof and fed through the inside of the tube to the other end of the tube to form an inner tube, an outer tube and a holding loop. The ends of the inner tube and outer tube are inserted through the formed holding loop and the outer tube is slid over the inner tube to close the holding loop, thereby forming a sliding loop from the insertion point. The sliding loop may fit around the wrist of the equipment user and the remote end may be tied to the item of equipment during use of the equipment.
Abstract:
A multiple-layer braided line having a high tensile strength composite steel core in which the innermost braided fibrous sheath layer is nylon, securely bonded to the composite steel core. An outer braided fibrous sheath is polyester formed over the inner sheath. The core is selected with a tensile strength over the desired rate load-carrying ability of the line, but less than that of the overall tensile strength of the inner and outer sheaths. The line is lightweight and has a high tensile strength and improved resistance to severing, melting and burning results, suitable for use by mountaineers, firemen and rescue workers. The line substantially eliminates backlash.
