Abstract: A connector plug for permanent connection to a plurality of conductors each having a bundle of wire strands. The plug includes a housing formed by complementary insulating shells which abut each other at their edges. Contact members secured in the shells each include a connection portion for connection within the housing to a respective one of the conductors at an end portion from which insulation has been removed over a predefined length to expose the wire strands. An insulating partition is disposed between each connection portion and the abutting edges of the shells to prevent any wire strands remaining loose after connection from projecting from the housing.

Abstract: For rendering the cable core of a telecommunication cable longitudinally water-tight, a sealing material is applied in plugs and at regular distances in and around the cable core (C) moved at a constant speed, by means of an injection head (43) which can be displaced in a reciprocating movement in the longitudinal direction of the cable core (C); the sealing material is injected by means of a rotating injection nipple (47) in a single continuous jet rotating in a radial plane around the cable core (C) (FIG. 4).

Abstract: A method of and apparatus for making the cable core of a telecommunication cable water-tight in the longitudinal direction, in which a filling material having a base of petroleum jelly is heated to a temperature above the drop point, is supplied under pressure to a filling head (5), is divided into a number of jets distributed over the circumference of the cable core, is passed through the filling head (5) with simultaneous conversion of the static pressure into kinetic energy and is injected through the outer layer of the cable core into the heart of the cable core, in which a reconversion of the kinetic energy into static pressure is effected and all the interstices and gaps between the single wires of the cable core are filled with the filling material.

Abstract: A gas-tight and moisture-tight, mechanically strong signal transmission cable having a cable core and a cable sheath which comprises a metal tape folded around the core and having a minimum thickness of 100 .mu.m, a layer of polyethylene adhering to the tape, a layer of polyamide-11 or polyamide-12, an armoring of reinforcing wires or tapes, and a synthetic resin outer sheath.

Abstract: A continuous process for manufacturing an optical cable element in which a central draw core is rotated with a periodically reversing direction of rotation. The draw core is then provided (i) with synthetic resin tubes in which one or more optical fibers are incorporated, or (ii) with an extruded synthetic resin sheath with grooves in which one or more optical fibers are laid. As a result of the rotation of the draw core, the grooves in the synthetic resin sheath or the synthetic resin tubes follow helical paths with periodically reversing directions of rotation.

Abstract: A method of and a device for providing a concentric layer of wire material on a cable (C), in which a number of wires (G) are taken simultaneously and in a tangential direction off a common rotating feed reel (27) on which the wires (G) are wound parallel to one another. The wires (G) are guided into the axial direction, are spread in the circumferential direction and are wrapped around the cable (C), which passes through a hollow shaft (11) supporting the feed reel (27). The method can be used both for armouring cables and for providing a screening.

Abstract: An optical cable element having a core and one or more optical fibers. The optical fibers may be provided with a separate secondary coating. The optical fiber or the secondary coating is connected to the core by a permanently elastic adhesive.

Abstract: An electric cord set having a plurality of stranded conductors and a connection plug with an identifying connection element, such as a grounding pin, the identified connection element being connected to a conductor identified by having a higher magnetic permeability than the other conductors. Preferably, the ground wire is made of wire strands similar to the other conductors, but contains 1 to 3 auxiliary steel wire strands. In a method and device for manufacturing such a cord set, the cord is arranged next to a magnetic sensing element and rotated about the cord axis automatically while the permeability is sensed. The cord is then fixed in a position of highest or lowest detected permeability, so as to identify the location of the unique conductor, and the plug is then connected.

Abstract: An armored cable and a method of manufacturing an armored cable, said cable having a helically wrapped zinc-plated steel armor. The steel armor band has zinc protective layer on its two sides, and uncoated edges, to reduce manufacturing costs and improve cathodic protection. The zinc protective layer thereby comprises a first layer portion consisting of a zinc-iron alloy and a second layer portion, on top of said first layer portion consisting of essentially pure unalloyed zinc and having a thickness of at least 90% of the total layer thickness.

Abstract: A method of, and apparatus for, manufacturing a stranded product from materials wound on feed reels journalled in a rotating feed cage. To permit operation at a maximum safe speed based on centrifugal force of the mass of material on the feed reels, an energy beam such as light is arranged to sense the diameter of the various feed reels. Cage rotation is then increased as permitted according to the observed diameter of charge of material on the reel having the greatest charge.

Abstract: Junction box for a cable comprising optical fibers, consisting of elongate flat holders wherein a splice and the remaining fiber lengths of a pair of fiber ends are stored in each holder. Two elongate plates clamp the holders therebetween. Two end plates are fitted to the end faces of the elongate plates. A housing surrounds the holders and the elongate plates. Each end plate is provided with a feedthrough opening and a pull relief for the optical cable. Each holder has two storage spaces, one for each of the remaining fiber lengths, which are interconnected, via an opening to a sidewall, through a recess. The splice is stored in the recess. Two connecting bolts, which keep the two elongate plates and the holder assembly together and which have a diameter larger than or equal to twice the minimum radius of curvature of the fibers to be coupled, pass through the storage spaces.

Abstract: An improved watertight cable is formed by employing as a sealing composition a mixture of a vulcanizable silicone rubber and as a diluent a cycloalkyl benzene the phenyl ring of which may be chlorinated.
