Abstract

448,440. Inductances. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and SMITH, C. G., c/o General Electric Co., Ltd., Wembley, Middlesex. Dec. 6, 1934, No. 35069. [Class 37] In a variable inductance for permeability tuning having separate coils L, S for long and short waves, the coils are spaced apart on a tubular former E of non-magnetic material, which is movable longitudinally in a gap between parts A, B of the core. The inner part B of the core is provided with insulating extensions C, D on each side. The cross-section of the parts A, B may be circular or rectangular ; in the latter case, the outer member A may be provided on the larger sides only of the rectangular section of B.
