Abstract

567,963. Inductances. NEOSID, Ltd., and GRENLY, M. Oct. 18, 1943, No. 17112. [Class 38 (ii)] A variable inductance for high-frequency circuits comprises a magnetic dust core made in two relatively movable parts, one of which a is pot-shaped and the other e discshaped, the parts being so shaped and dimensioned that the magnetic circuit is never completely closed.
