Abstract

940,903. Sealing rings. BADISCHE ANILIN- & SODA-FABRIK A.G. Feb. 26, 1962 [Feb. 27, 1961], No. 7356/62. Heading B5A. Sealing rings are formed with their sealing faces in contact with smooth lapped steel plates. The rings are moulded by injection moulding or bulk polymerization, the steel plates being incorporated in the mould. The rings may be made from a polyamide, polyethylene, polytetrafluoroethylene or polystyrene.
