Abstract: In known overhead telephone cables comprising two individual encased and stranded conductors, each consisting of a plurality of copper wires for the transmission of signals, and steel wires for load bearing purposes, the problem of relatively high susceptibility to corrosion at leakage points in the casing due to water penetration is solved by replacing the steel wires with bundles of stretch-resistant synthetic fibres, e.g. aromatic polyamide fibres, and the tendency of spirally wound synthetic fibres, or bundles of fibres, to shift towards the center of the conductor when the cable is under tension, and thus allow the cable to elongate is prevented by arranging the copper wires and bundles of fibres so that they position themselves mutually. The coherency of the bundles of fibres required for this purpose may be obtained, for example, by stranding or twisting the fibres in the bundle or impregnating the bundle with a resin, preferably colophony.

Abstract: Telecommunications cable formed by locating a plurality of conductors in a group in an open array, which is preferably planar, and shaping the group into arcuate configuration around a longitudinal axis with the conductors extending generally in the direction of the axis. A layer of insulation is then provided around the group to hold it in its planar configuration.

Abstract: A remote control cable has a central core formed from two conducting wires separated over their entire length by a textile element with which the wires are in intimate contact, preferably slightly embedded therein, the whole being covered by a coating of a thermofusible material. The central core is strengthened by filamentary reinforcing elements arranged in parallel to the conducting wires and by at least one, preferably two, layers of braiding over the reinforcing elements. The central textile element maintains the conducting wires separated and parallel to each other during manufacture and under conditions of use. The cables may be used for transmitting signals, e.g. electrical pulses, to remote objects, for example, to transmit directions for controlling objects moving at high speeds, e.g. up to 300 m/second or higher and over distances up to 4000 meters or more.

Abstract: A high-strength textile ribbon disposed against the webbing of the core of a parallel lead cable significantly enhances the breaking strength of the incorporating cable without significantly affecting its flexibility or electrical properties. Breaking strength may be further enhanced by bonding the ribbon to the webbing and the adjacent portion of the cable sheath.

Abstract: A low loss buoyant coaxial cable has its buoyant material placed between conductors to allow for maximum cable cross section for electrical transmission. In addition the strength members are placed radially inward of the center conductor to reduce wearing of the strength members and keeping the electrical performance independent of the electrical properties of the strength members. An alternate embodiment has buoyant material centrally located and the strength members placed with buoyant material between the coaxial conductors.

Abstract: A unitized marine umbilical cable carrying any number or combination of conventional elements such as hoses and electrical cables. A center stress member disposed along the axis of the marine umbilical cable is capable of supporting an underwater device such as a diving bell should the primary down line break. Cylindrically surrounding the stress member is a compression extrusion of a high strength highly resilient elastomer around which are helically cabled various conventional elements. Within the interstices between the high strength elastomer and the helically cabled elements is a resilient fill material. The resilient fill material and high strength highly resilient, low durometer elastomer serve as a radial shock absorber against tensional impact upon the umbilical or radial forces thereupon.

Abstract: A multiple caged armored electromechanical cable is provided which is characterized in being torque balanced and strength tapered throughout its entire length. The selective strength tapering of the cable permits the orientation of the cable such that the strongest portion thereof will support the entire cable and the weakest portion thereof will support only itself and whatever instrumentation is desirable. A slip sleeve mechanism is provided for retaining portions of the strength tapered elements of the cable to prevent inadvertant electrical shorting as well as providing for a relative slippage of the tapered strength elements with respect to select other elements of the cable.

Abstract: The cable comprises a plurality of electrical conductor elements and a plurality of tensile load-bearing elements combined with the conductor elements to form the cable. The tensile-load-bearing elements are made of high-tensile strength synthetic plastic material.

Abstract: A yarn or fiber is incorporated into the jacket of a long suspended small ameter cable for reducing low velocity current cable strumming in water. The yarn or fiber comprises at least one-quarter of the strands of a braided cable. A nap or mossy cable effect is produced when the jacket is brushed.

Abstract: An electromechanical cable is adapted for deployment along a generally straight path and when thus deployed to be substantially free of torsional reactions resulting from changes in tensile stress in the longitudinal direction of the cable. The cable includes a plurality of strain members arranged in an annular configuration. When the cable lies straight and untwisted the strain members are also straight, parallel to the longitudinal axis of the cable and parallel to each other. The strain members are loosely confined within the cable structure so that when the cable is subsequently twisted they are free to move into helical positions relative to the axis of the cable.The cable is first wound into a coil and concurrently pretwisted about its own axis by approximately 360.degree. for each loop of the coil. After being transported to the deployment site, the cable is pulled off the coil without relative rotation between the delivered end of the cable and the coil, so that the pretwist of the cable is relieved.

Abstract: An electric cable comprising a reinforcing member including a roving of strands of reinforcing elongated fibers and synthetic resin having the weight of 15 to 50 percent as against that of the strands and bonding the strands of the roving. The reinforcing member may be in the form of an armoring member, a tensioning member and an insulation.
