Abstract

139,226. Seymour, T. S., and St. Helens Cable &. Rubber Co. June 22, 1917. Fibrous plastic compositions; plastic compositions containing india-rubber &c. - Electric cables are covered with a protective and insulating composition which is substantially rigid when cold but readily pliable when warmed, whereby the cable can upon heating be bent as desired. A suitable material comprises rubber combined with a large proportion of sulphur to which may also be added asbestos, shellac, gutta-percha, balata, silica, magnesia, chalk, zinc oxide, and the sulphates of antimony. After application to the cable, it is vulcanized so as to produce a covering of the nature of vulcanite, ebonite, or the like. As an example, the following percentage proportions are given: rubber 35, reclaimed rubber 15. rubber substitute 5, ebonite dust 10, silica 10, magnesia 10, and sulphur 15. Reference has been directed by the Comptroller to Specifications 17066/94, 22574/95, 25286/98, 24874/07 and 10440/14, [Class 36, Electricity, Conducting &c.].
