Abstract:
A mooring rope comprising two different types of synthetic materials which provide the mooring rope with a larger diameter and greater wear resistance without causing the strength of the rope to increase. The mooring rope may comprise a plurality of rope strands, wherein each strand has a core comprising primarily polypropylene with high molecular weight polyethylene rope yarns twisted around it. The production process for manufacturing such mooring ropes is disclosed, too. Synthetic materials include liquid crystal polyester, aramid and ceramics.
Abstract:
Disclosed is a method for producing a high strength synthetic strength member containing rope 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 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 formed about the strength member. The first and second synthetic portions having differing elasticity values, the second synthetic portion having greater elasticity than the first synthetic portion. Preferably, the elasticity of the second synthetic portion is in a range of from 20% to 550% when measured at any temperature within 2°C of 0°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).
Abstract:
A rope and a method of constructing the rope. The rope may be of 12 x 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:
Die Erfindung betrifft ein Verfahren zur Herstellung eines Drahtseils (1), bei dem ein Kernstrang (3) verdichtet wird und danach Litzenstränge (2) auf dem Kernstrang (3) verseilt werden, dadurch gekennzeichnet, dass der Kernstrang (3) zur Glättung seiner Oberfläche (10) vor Verseilung der Litzenstränge (2) gehämmert wird. Zweckmäßigerweise wird auf den Kernstrang (3) vor der Verseilung der Litzenstränge (2) eine Kunststoffschicht aufgebracht, wobei die Litzenstränge (2), vorzugsweise unter Erhitzung der Kunststoffschicht (7), in die Kunststoffschicht (7) eingedrückt werden. In der bevorzugten Ausführungsform der Erfindung ist der Kernstrang ein Kernseil (3) und die Litzenstränge Litzen (2) des Drahtseils (1) oder der Kernstrang ist eine Herzlitze und die Litzenstränge sind äußere Kernlitzen eines Kernseils des Drahtseils. Die Erfindung betrifft ferner das Drahtseil (1) und eine Vorrichtung zur Herstellung des Drahtseils (1).
Abstract:
A cable for use in a safety barrier is provided. A cable for use in a safety barrier may include a plastic core wire and a plurality of metal wires disposed adjacent to and longitudinally to the plastic core wire. The cable may be pre-stretched prior to installation in the safety barrier. A method of making cable for use in a safety barrier may include (a)providing a plastic core wire, (b) disposing a plurality of metal wires, each metal wire disposed adjacent to and longitudinally to the plastic core wire, and (c) prestretching the cable prior to installation in the safety barrier.
Abstract:
A braided fibre rope (10), and associated method of construction thereof, having a first end and a second end, said rope further comprising a core (100) having a low-friction surface, said core (100) being insignificant with regard to a tensile load bearing function, while significantly resisting crushing of the rope. Said rope is preferably of the braided braid type comprising a number of yarns (14) braided into a sub-rope (16), which may also have a core, and a number of sub-ropes (16) braided around the core (100).
Abstract:
Disclosed herein is an endoscopic extraction device which retains its operative usefulness for longer periods of time, and therefore needs to be replaced less frequently. This extended instrument life is accomplished through the use of a composite wire construction, which includes an inner monofilament wire (11) of nitinol material surrounded by six stranded stainless steel wires (12a-f). A wire construction in which a nitinol wire (21) is surrounded by five stranded stainless steel wires (22a-e) is also disclosed. After constructing a wire basket in the normal manner using this material, heat is applied to the formed basket in its pre-formed shape to set the memory characteristics of the inner nitinol core.
