Abstract:
A method and device for handling an elongate strength member. In the method, an elongate strength member with a plurality of elongate composite rods, or metal wires or plastic fibers are bundled together with the composite rods, or metal wires, or plastic fibers in a generally parallel and untwisted and un-spiraled arrangement when the elongate strength member is extended along a generally straight path, wherein the composite rods are longitudinally and rotatably moveable relative to each other. It is then twisted relative to a longitudinal dimension of the elongate strength member and the path of the elongate strength member is curved, such as by coiling.
Abstract:
A safety elastic rope includes an elastic outer tubular rope having two longitudinally opposite first fixing ends, and an elastic inner rope inserted into the outer tubular rope and having two longitudinally opposite second fixing ends. The inner rope is more elastic than the outer tubular rope, and has substantially the same length as the outer tubular rope. The second fixing ends are connected respectively to the first fixing ends.
Abstract:
Umbilical device, where the device has a longitudinal axis (x), and includes at least one elongated electrical cable or tube element; and an elongated load bearing component along the longitudinal axis (x) and having an external surface including at least one groove disposed along the longitudinal axis (x) and parallel thereof. The component includes a central core encompassed by a plastic or elastic layer, which is provided with the at least one groove, where the groove is designed for holding the cable or tube element within it, while allowing the cable or tube element to move substantially radially in the groove when the umbilical is bent and that the layer is made from several plastic or elastic elements.

Abstract:
The instant invention is a rope. This rope includes a blend of filaments including a first filament, and a second filament. The second filament is fluorocarbon polymer filament.
Abstract:
Tensioning bundle includes tensioning members running parallel to one another such as stranded wires or single wires. According to the invention the tensioning bundle as a whole is covered with at least one synthetic resin in an extruder. For tensioning such bundles the tensioning members may be tensioned individually or jointly.
Abstract:
A rope for traction of a double structure of a core member coated with a sheath member, in which said core member comprises a molecularly oriented shaped article of an ultrahigh molecular weight polyolefin, and said sheath member comprises a braid. The rope proposed herein is light in weight, floatable on water, easy to handle and excellent in safety to human bodies and weatherability.
Abstract:
Well tools are run into a well, usually a deviated well, using a composite wireline cable made up of a bundle of parallel slideable composite rods covered with a flexible protective sheath.
Abstract:
An elongated article such as a rope or cord having a series of fairings spaced apart along its length is produced in a continuous manner by the method and apparatus of the present invention. The rope comprises a core having a plurality of yarns surrounded by a layer of resilient material, and a braided jacket surrounds the core and anchors the fairings thereto. The fairings are provided by a resilient fairing yarn which is fed toward the core and which is manipulated by a needle during braiding of the jacket to cause each fairing to have a base portion anchored between the jacket and the resilient layer of the core and streamer portions extending outwardly from the base portion. The needle is mounted for reciprocation parallel to the moving core upstream of the braider, and the fairing yarn passes through the eye of the needle and a first length is displaced through the path of movement of the braid yarns into engagement with a gripping assembly located downstream of the braid yarns. The gripping assembly holds the first length of fairing yarn so that as the needle retracts, another length of braid yarn is pulled through the needle-eye. Continued operation of the braider causes the jacket to be applied around the portion of the fairing yarn engaged with the core, thereby forming the base portion for the next fairing. A control system is disclosed for synchronizing movement of the needle with the displacement of the rope and for adjusting of the spacing between the fairings.In another embodiment, a method and apparatus is disclosed for producing a faired article which does not have a separately-formed core.
