Abstract: Metallic load-carrying elements (3,23) are helically spun around a central member (1,21) comprising a supporting member or members (9,24) constituting a structure (4,24) which defines at least one passage (6,26) wholly accommodating at least one electrical or optical transmission element (7,27). The transmission element is thereby protected against stresses applied to the load-carrying elements. The central structure is radially and longitudinally self-supporting. The central member (1,21) is formed by causing the supporting member or members (9,24) and the transmission element or elements (7,27) to converge to a point from which the central member (1,21) is withdrawn continuously. The load-carrying elements (3,23) are subsequently applied to the central member (1,21). Cables of practically unlimited length can be produced.

Abstract: An elongate terminal body has a longitudinal bore which receives a wire rope or strand. A deformable member surrounds the rope or strand in an enlarged part of the bore adjacent the end at which the rope or strand enters. The terminal body is compressed to grip the rope or strand so that the deformable member is gripped between the terminal body and the rope or strand. The deformable member dissipates transverse and longitudinal vibrations transmitted along the rope or strand towards the terminal body.

Abstract: This specification describes a clamp comprising a ductile elongate clamp body having a longitudinal channel which receives a hard tubular element divided longitudinally into at least two separable parts held together by retaining means. The clamp is applied to a plastics-sheathed rope by removing the sheathing over a length greater than that of the tubular element but less than that of the body, positioning and retaining the parts of the tubular member about the unsheathed length, inserting the tubular element into the channel in the body, and compacting the ductile clamp body.
