Abstract:
A cord material suitable for use in lined textile structures with a gliding component includes a plurality of uniform strands, and a deviant strand. The deviant strand is different from the uniform strands in some characteristic affecting aerodynamic or hydrodynamic properties of the cord, such as size or surface properties. Each uniform strand can have a substantially equal cross section area, while the deviant strand has a cross section area at least five times greater than one of the uniform strands. The strands can be braided or woven together. A major benefit of the material can be that vibration induced drag is significantly reduced or eliminated in lines made with the material. Another advantage is that lines made from the material can have more consistent, predictable line drag, which can improve the quality of handling.
Abstract:
In an elevator rope, a plurality of steel outer layer strands are twisted together on an outer circumference of an inner layer rope. The inner layer rope has: a fiber core; a plurality of steel inner layer strands that are twisted together directly onto an outer circumference of the fiber core; and a resin inner layer rope coating body that is coated onto the outer circumference. A diameter of the inner layer strands is smaller than a diameter of the outer layer strands. The inner layer strands are greater in number than the outer layer strands.
Abstract:
A belt for suspending and/or driving an elevator car includes a plurality of wires arranged into a plurality of cords. The plurality of cords includes one or more inner cords located at an innermost portion of the belt relative to a lateral end of the belt and one or more outer cords located laterally outboard of the one or more inner cords. The one or more outer cords have a construction distinct from the one or more inner cords. A jacket substantially retains the plurality of cords.
Abstract:
A high-security cable is provided, wherein the high-security cable is capable of achieving a smoothing of a work-to-break energy curve. The high-security cable is manufactured of a mixture of plastic yarns or of plastic yarns and metal wires, wherein the cable comprises a first constituent part of untwisted or twisted yarns, or untwisted or twisted yarns and metal wires, a second constituent part of doubled yarn, the doubled yarn manufactured of plastic yarns or of plastic yarns and metal wires, and a third constituent part of cord manufactured from the doubled yarns, wherein the doubled yarn is manufactured from plastic yarns or of plastic yarns and metal wires. The high-security cable can be used as a safety arrester cable, and can also be used to form a netting to serve as safety arrester netting or falling-rock protection netting.
Abstract:
The object of the invention is a traction sheave elevator and a rope (3) that contains metal as a load-bearing material, such as the suspension rope of an elevator, which rope comprises at least one or more strands (7) laid from metal wires (9) and which rope (3) is lubricated with a lubricant (8). Another object is the use of the aforementioned lubricant for lubricating the rope (3). The lubricant (8) comprises at least oil and thickener, which thickener in the lubricant (8) comprises at least 10% or more of the mass of the lubricant (8).
Abstract:
A reduced drag cable for use in vertical wind tunnels and other applications with a change in the spacing and/or size of the strands of a standard twisted wire cable is disclosed. The perimeter strands of one embodiment all have a standard diameter, with the exception of one or more wires with different diameter from the other perimeter strands. The different sized strand forms a helical feature around the cable, creating a non-circular profile to reduce drag in air.
Abstract:
The cable includes a substantially metallic central core (3) and outer strands (2) formed from at least one layer of metal wires (21), particularly steel wires, which are stranded over a core element (22) made from synthetic material, preferably a thermoplastic material, this being with a pitch similar to that of the strands (5,6) with which the core (3) is formed, it being possible for the latter to be entirely metallic or hybrid. These cables are intended particularly for use as a lifting cable, particularly elevator cables, or other multicable installations with transmission by means of adherence.
Abstract:
A high-elongation composite cord used for reinforcing a rubber composite such as a wheel tire and a conveyor belt. It is made by twisting a plurality of strands each made by twisting a plurality of brass-plated steel filaments and monofilaments of organic fiber. Before twisting the cord, monofilaments of organic fiber are put in the gaps formed between the adjacent strands so as to prevent fluidized rubber from penetrating into a center core formed in the cord after the cord has been covered with rubber. The monofilaments should have a diameter small enough not to protrude from a circle circumscribing the cord and large enough to close the gaps between the adjacent strands.
Abstract:
The present rope is torsion free mainly because it has an inner rope formed by an inner layer of strands which is surrounded by an outer layer of strands and since the inner rope is constructed of at least three flattened strands and at least three round strands which are smaller than the flattened strands to fill the spacings between adjacent flattened strands. The inner strands surround a center member of elastic material.

1,247,604. Vehicle tyres. GUSTAV WOLFSEIL-UND DRAHTWERKE. 13 Oct., 1969 [16 Oct., 1968; 11 June, 1969], No. 50257/69. Heading B7C. [Also in Division D1] A strand of polygonal cross-section having filaments constituting an inner lay and an outer lay, is characterized in that the outer lay filaments are arranged in groups of three associated with each inner lay filament, two of the outer lay filaments in each group being thinner than the third, the strand having no filament extending coaxial with the strand axis. In Fig. 2 there are three inner filaments 9, 10, 11 and nine outer filaments. Inner filament 9 is associated with three outer filaments 9a, 9b, 9c and filaments 9a, 9b are thinner than filament 9c. Fig. 1 illustrates an embodiment in which two inner filaments 1, 2 are associated with six outer filaments. Inner filament 1 is associated with the three outer filaments 3, 4, 5 and filaments 3, 4 are thinner than filament 5. Fig. 3 (not shown) illustrates an embodiment in which there are four inner filaments and twelve outer filaments. The Specification also describes cables made from the strands. The strands or cables may form an endless ring and may be embedded in a vehicle tyre. The filaments may be of metal, glass, plastics or any combination of these materials.
