Abstract

616,880. Inductances. BRITISH THOMSONHOUSTON CO., Ltd. May 22, 1946, No. 1552]. Convention date, May 25, 1945. [Class 38 (ii)] [Also in Group XL (c)] A variable inductance device comprises a coil 1, a relatively movable core 2 of magnetic material and a mechanically coupled variable capacitor 5 to neutralize changes in coil capacitance resulting from core movement.
