Abstract

702,416. Cables. LIGNES TELEGRAPHIQUES ET TELEPHONIQUES. Sept. 27, 1951 [Dec. 14, 1950], No. 22625/51. Class 36 [Also in Group V] Fig. 1 is an end view and Fig. 2 a longitudinal sectional view of a half-tube made of plastic material. This half-tube has transverse semicircular walls 3 in which recesses 3<SP>1</SP> are formed. Two such half-tubes are used for the insulation of telecommunication circuits, being fitted around a central conductor, the walls 3 registering to form circular discs.
