Abstract
253,691. St. Helens Cable & Rubber Co., Ltd., and Harrison, H. C. May 16, 1925. Insulating coverings for cables and conductors. -In order to prevent the penetration of water along the interstices between the cores of multicore cables, the insulating coverings 2 of the cores, the sheathing 1, and the interposed filling are vulcanized solid at points 4 or throughout the length of the cable with the exception of those parts. such as the ends, where it is necessary to provide electrical connections. In the manufacture of the cable, the insulated cores and sheathing are coated with French chalk or other material at those parts where it is required not to vulcanize them together.
