Abstract

1,153,167. Making cams. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 4 Dec., 1967 [28 Dec., 1966], No. 57970/66. Heading B3A. [Also in Division H1] A needle roller bearing has its end portions electro-plated so as to provide identical non- circular axially aligned cross-sections. These form cam surfaces co-operating with a cylindrical member to provide a slit 10 of variable width for use in a mass electrometer.
