Abstract:
A titanium alloy cable comprises a plurality of individual wire filaments (20). Groups of wire filaments are twisted together in a first helical direction around a central wire filament to make a strand (10). A plurality of strands are twisted together in a second helical direction around a core strand to make a strong, flexible cable. The first helical direction has the opposite sense to that of the second helical direction. In one embodiment, the cable has one hundred and thirty three wire filaments, each of diameter 0.0025 inches (64(my)m), arranged in nineteen equivalent strands and the titamium alloy is Ti-6 wt % A1-4 wt % V.
Abstract:
A plurality of wire elements for use in an energy recovery device comprising Shape Memory Alloy or other Negative Thermal Expansion (NTE) material, wherein at least one wire element is fixed at one end and free to move at a second end, such that the wire elements are arranged adjacently and are in friction or interference contact with each other and are secured at the outer perimeter of wires utilising a securing means. In such arrangement, during the operation of the bundle arrangement in a heat engine system, the plate elements act to transmit the aggregated force generation of the wire grouping and thus usefully recover and transmit power.
Abstract:
Câblé textile aramide (50) à au moins triple torsion (T1, T2, T3), comportant au moins N brins (20a, 20b, 20c, 20d), N étant supérieur à 1, retordus ensemble selon une torsion finale T3 et une direction finale D2, chaque brin étant constitué de M pré-brins (10a, 10b, 10c), M étant supérieur à 1, eux-mêmes tordus ensemble selon une torsion intermédiaire T2 (T2a, T2b, T2c, T2d) et une direction intermédiaire D1 opposée à D2, chaque pré-brin consistant lui-même en un filé (5) qui a été tordu préalablement sur lui-même selon une torsion initiale T1 (T1a, T1b, T1c) et la direction D1, dans lequel au moins la moitié des N fois M filés sont des filés aramides. Ce câblé textile est avantageusement utilisable comme renfort dans les pneumatiques pour véhicules, en particulier dans la ceinture ou dans l'armature de carcasse de ces pneumatiques.

Abstract:
The invention is directed to materials comprising polylactic acid (PLA). In accordance with the invention, PLA material is stretched in at least the machine direction at a total stretch ratio of 1:4 or more. These materials have excellent biodegradability and find use in horticulture, in particular for tying up plants or parts thereof.
Abstract:
A securing device is provided comprised of a reactive fiber component and at least one of a terminating fiber component and an initiating fiber component. The reactive fiber component includes at least one of the following: an undrawn polymer fiber and a substantially undrawn polymer fiber, wherein the first reactive fiber component is operative to stretch responsive to a load. The terminating fiber component is in a compressed state and is operative to elongate to a length at which the terminating fiber component is operative to prevent further stretching of the first reactive fiber component responsive to the load. The initiating fiber component is operative to break responsive to a predetermined force and permit the first reactive fiber component to stretch responsive to the load.
Abstract:
The invention relates to an abrasion resistant fabric containing ultra high molecular weight polyethylene (UHMWPE) filaments and thermotropic liquid crystal polymers (LCP), the use thereof as protective means and to a protective cover containing said fabric. In particular, the invention relates to a rope and to a roundsling containing the protective cover.
Abstract:
According to the invention, the elastic link for adjusting the distance between two members, at least one of which is mobile, is characterised in that it comprises at least two elastic yarns (1, 2) each attached through one of the opposite ends thereof to two points (6-7; 6-8; 6-9; 6-10) distant from each other of an intermediate portion (5a) of a strap (5) located between the extreme portions (5b, 5c) of the latter, under conditions such that when a tensile force is applied on said strap, the first elastic yarn (1) is stretched first, the second elastic yarn being then stretched based on the magnitude of the applied tensile force.
Abstract:
Rope of a hoisting appliance and method for manufacturing rope of a hoisting appliance (1), which rope of a hoisting appliance comprises a core wire (2) or similar and a plurality of outer wire layers, each of which comprises a plurality of wires (3). The rope (1) comprises at least one such wire layer, essentially all the wires (3) of which are at essentially the same distance from the core wire (2) and contain composite material and of which at least a part are essentially wedge-shaped in the shape of their cross-section. The hoisting appliance rope (1) can comprise at least one such wire layer that comprises wire bundles essentially at the same distance from the longitudinal axis of the rope and which wire bundles comprise wires (3) comprised of composite, and at least a part of which wire bundles are essentially wedge-shaped in the shape of their cross-section. In the method a plurality of wires (3) are directed into at least one outer layer (L) as a part of the rope (1) such that at least a part of the wires (3) forming the rope (1) are composite and in the method at least a part of the composite wires (3) intended to be a part of the rope (1) are coated with polymer and the wires (3) are directed into the proximity of each other as a part of the rope (1).
