Abstract

344,692. Bearings. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN, 13A, Emmasingel, Eindhoven, Holland. April 4, 1930, No. 10753. Convention date, April 19, 1929. Addition to 286,436 [Class 39 (i), Electric lamps, Arc &c.]. Drawings to Specification. [Class 12 (i).] Rotary sliding members formed of a mixture of copper with 0À5-3 per cent, and preferably 1 per cent of graphite, bear on a member of tungsten, molybdenum or other metal or alloy having a lower coefficient of expansion and greater hardness than the mixture.
