  • Patent number: 7305814
    Abstract: Safety arrester cables are provided to connect a wheel of a racing car to its chassis. The safety arrester cable is formed of a multitude of untwisted windings that form closed loops. An open tab is formed at both ends of each of the windings. The windings in the safety arrester cable are manufactured to be comprised of more than 70% nickel or an austenitic Ni—Cr alloy. A safety arrester cable comprised of such wires, and having a diameter of about 12 mm, achieves a maximal tear force of about 58 kN and a work absorption until reaching a maximal tear force of 8,900 N.m.

  • Patent number: 7107751
    Abstract: The safety of safety cables may be improved, whereby the system of cable and attachment eye is embodied together such that a greater work-to-break energy is possible. The cable is prepared from a blended yarn, comprising fibres made from relatively rigid, highly tear-resistant plastic filaments from a selection of PBO, carbon fibres and p-aramides and a proportion of fibres made from relatively elastic plastic filaments from selection of m-aramides, PBI, polyurethane (elastane) and polyester. The arrester cable is produced from the blended yarn the ends of which have, for example, been immersed in a resin. The end of the cable thus rests in an attachment eye, comprising a conical tubular section, in which the thickened end of the cable is held by wedging.
