Abstract:
A bicycle lock apparatus comprises a locking mechanism selectively changeable between locked and unlocked configurations and an elongated securing arm. The securing arm includes a first end adapted for removable insertion into the locking mechanism it is unlocked, and for non-removable connection when it is locked. The securing arm further includes an armored sheath extending a length of at least seven feet and having an annular wall formed from at least two spirally-wound metallic strips interwound with one another to define a continuous interior cavity. The armored sheath is flexibly obedient to be reconfigurable into curved positions and holds the positions after the bending force is removed. The securing arm further includes a reinforcing core disposed within the interior cavity, the reinforcing core including at least one bundle of elongated non-metallic fiber material having a tensile strength-to-weight ratio of at least 1000 kN·m/Kg extending between the first and second ends.
Abstract:
A rope and a method of constructing the rope. The rope may be of 12×12 braided construction and include a core for its length. The rope includes a plurality of primary strands, and each of the primary strands includes a plurality of fibers which may be made of a high-friction material. The rope also includes a secondary strand surrounded by the plurality of primary strands. The secondary strand includes a plurality of fibers which may be made of a low-friction material.
Abstract:
A wire cable and a device and method for producing the wire cable, wherein a core strand is compacted and then braid strands are stranded on the core strand. The core strand is hammered before stranding of the braid strands in order to smooth the surface thereof. A plastic layer is applied to the core strand before stranding of the braid strands. The braid strands are pressed into the plastic layer while the plastic layer is heated. The core strand is a core cable and the braid strands are strands of the wire cable or the core strand is a heart strand and the braid strands are outer core strands of a core cable of the wire cable. A greater breaking strength of the wire cable is obtained by hammering the core strand in order to smooth it than by compacting a core strand with a roller compressor.
Abstract:
A twistable security cable including a cable and a coupling device. The cable includes a central core, two or more wire groups positioned about the central core, and an outer coating. The central core is structured to retain a shape to which it is deformed, and each of the wire groups includes two or more braided or twisted wires. The coupling mechanism is structured to selectively retain first and second ends of the cable in close proximity to one another.
Abstract:
Disclosed is a method for producing a high strength synthetic strength member (7) containing rope (1) capable of being used with powered blocks where such rope has lighter weight and similar or greater strength than steel wire strength member containing ropes used with powered blocks. Disclosed also is the product resulting from such method. The product includes a synthetic strength member, a first synthetic portion (9) and a second synthetic portion. The first synthetic portion is enclosed within the strength member and the second synthetic portion is situated external the strength member. At least a portion of the second synthetic portion also is situated internal a sheath (8) formed about the strength member. The second synthetic portion has a minimal of 8% at a temperature of between negative 20 and negative 15° C.

Abstract:
The invention relates to a method for producing a wire cable (1), wherein a core strand (3) is compacted and then braid strands (2) are stranded on the core strand (3), characterized in that the core strand (3) is hammered before stranding of the braid strands (2) in order to smooth the surface (10) thereof. A plastic layer is advantageously applied to the core strand (3) before stranding of the braid strands (2), wherein the braid strands (2) are pressed into the plastic layer (7), preferably while the plastic layer (7) is heated. In the preferred embodiment of the invention, the core strand is a core cable (3) and the braid strands are strands (2) of the wire cable (1) or the core strand is a heart strand (3) and the braid strands are outer core strands of a core cable of the wire cable. A greater breaking strength of the wire cable (1) is obtained by hammering the core strand (3) in order to smooth it than by compacting a core strand (1) with a roller compressor. The invention further relates to the wire cable (1) and to a device for producing the wire cable (1).
