Abstract

661,802. Inductors. COLE, Ltd., E. K., and KING, A. E. May 12, 1950 [May 13, 1949], No. 12762/49. [Class 38 (ii)] In a preset type radio inductance coil comprising windings d on a former b, a screwthreaded spindle f bearing an iron dust core e is adjustably carried by the socket part a of an ordinary dress press-fastener press-fitted on one end of the former b, the socket retaining springs k engaging the screwthread. Former lugs i projecting through socket openings prevent relative rotation. In a modification, a panel mounting coil has its socket carried by a mounting sleeve secured to the former.
