The grooves are closed at the edges (16, 17) of the slot by transverse walls (22). A method for manufacturing a grooved sheath includes extruding and molding an annular sheath with a longitudinal flat strip level with flute edge hollows, cutting the flat strip along one of its flute edges to form a tongue that is integral only with the other flute edge. The method further includes heating the sheath and cooling it, while passing it between cones or calenders to bring the flute edges together, whereby the tongue passes between the cut edge. A device for making a grooved sheath includes a molding machine with two series of symmetrical parallel shells.

Abstract: An undercarpet cable (40) includes a plurality of longitudinally extending interlocking segments (42--42). The segments are designed each to have an optical fiber (33) housed therein or when interlocked in an assembly to provide a longitudinally extending cavity for receiving an optical fiber. The assembly of segments is capable of being routed along at least two paths which are normal to each other. Advantageously, longitudinal relative motion between adjacent ones of the segments and between the optical fiber and the segments is allowed. As a result, the cable may be routed in tortuous paths under a carpet to service workstations as desired.

Abstract: A current bar arrangement includes a flat, two-wire, flexible cable (2) provided with a rubber-like insulation (2.3). The cable has a plurality of holes (2.4) stamped in the insulation at a mutual distance between the two wires (2.1, 2.2). The two wires are laid bare in each case for a short distance. The current bar arrangement also has a cable channel (1) substantially form-stable in the lengthwise direction and substantially U-shaped in profile for receiving and holding the cable. The current bar arrangement is very versatile and variable in use, but especially in low-voltage halogen lighting systems. It is distinguished by an especially simple technical construction and, associated with this, by a very low production cost.

Abstract: A portable crossover of high strength elastomeric material, such as polyurethane resin, which is placed upon the ground in the path of a high tonnage earth moving vehicle. A cable, supplying electrical power to an electric excavator, is placed in a U-shaped channel or recess and a strip insert of elastomeric material is placed over the cable thereby preventing debris from damaging the cable or causing subsequent removal of the cable to be difficult. The crossover is shaped particularly to provide ramps on each side for the vehicle to engage and has central load-carrying shoulders which restrict central deflection of the crossover, under the wheels of the vehicle, such that vehicle load is not imposed on the cable. A towbar, of rigid plate material or a cable or chain fixedly joins one end of the crossover whereby a tow vehicle may connect to and relocate a crossover from place to place as needed, upon removal of the cable from the channel.
