Abstract
1,082,226. Inductors and transformers. PAINTON & CO. Ltd. June 29, 1966 [April 2, 1965], No. 14134/65. Heading HIT. A variable inductor or transformer consists of a coil 14 (Fig. 3) moulded in or beneath the surface of a plastics casing 2, a core carrier 22 being slidably movable in chamber 12 by a rotation of a lead screw 16. Core carrier 22 is provided with a wire spring member (27) (Fig. 5, not shown) which engages with the threads 17 of the lead screw 16 but slides over them when rotation of screw 16 brings the core to a limit position. Rotation of core 22 is prevented by an integrally moulded bead 19 which engages a groove in the underside of the core carrier and covers a lead to one of the terminal pins. The lead screw may be made of stainless steel and the core of sintered iron dust.
