Abstract

754,718. Watch bearings. LIP SOC. ANON. D'HORLOGERIE. Feb. 26, 1954 [Feb. 27, 1953], No. 5766/54. Addition to 735,376. Drawings to Specification. Class 12 (1). In the bearing for horological mechanisms according to the parent Specification, the synthetic resin used for the bearing is first subjected to a mechanical reduction, e.g. by drawing, rolling or pressing, at a temperature from 0‹ to 100‹ C., with a view to reducing " flow " while facilitating machining. The synthetic resin may contain loading agents such as lead, graphite, molybdenum sulphide, molybdenum bisulphide and mica.
