Abstract

647,206. Reciprocating motors. BRIGGS, G., and BRITISH VACUUM CLEANER & ENGINEERING CO., Ltd. June 20, 1947, No. 16376. [Class 35] [Also in Groups XIX, XXXVI and XXXVIII] The receiver of a remote position indicator includes a vibrator in an iron casing comprising an A.C. energized coil 78 with a central iron core; and an axially magnetized ring 97 which vibrates inside a compartment 80 of the housing, being alternately attracted and repelled during each A.C. cycle. This vibrator prevents sticking at the bearings.
