Abstract

645,785. Conduits. GRUBB, R. G., and MORRIS, S. W. M. Oct. 6, 1948, No. 26095. [Class 36] A conduit for electric cables comprises a tube 11 of insulating material having one or more metal wires or ribbons 10 extending continuously therethrough and embedded in the inner surface of the conduit to provide an earthing connection exposed to the interior of the conduit. The conductor is embedded in the tubing by feeding the wires or ribbons continuously to an extrusion machine during the extrusion of the tubing. The conductor, which may extend longitudinally or helically along the tubing, may comprise a metal wire or ribbon or a wire mesh, and may have a serrated surface by which it is held in position within the tube. The tube may be made from natural or synthetic rubber or a synthetic resin.
