Abstract

778,189. inductors. GENERAL ELECTRIC CO., Ltd., and STENNING, L. C. April 6, 1955 [Jan. 18, 1954], No. 1460/54. Class 38 (2). [Also in Groups XXXIX and XL (c)] An inductor for use in a magnetic amplifier at high frequencies has a saturable ferromagnetic core formed by two bundles 4a, 4b of high permeability nickel-iron alloy wires which have an insulating coating of ceramic. The bundles are located side by side and are contained in insulating sleeves 14, 15 each having wound uniformly along its whole length half of a control winding (not shown). A former 16 surrounds the sleeves 14 and 15 and carries the inductor which may be a centrally disposed pie-winding. The two halves of the control winding are connected so as to cancel out voltages induced when the inductor is energized. The core parts 4a, 4b may be the two limbs of a U-shaped core and may be formed from a strip of foil of the ferromagnetic material known under the Registered Trade Mark " Mumetal." Specification 778,191 is referred to.
