Abstract

565,895. Inductances. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. May 29, 1943, No. 8608. Convention date, May 29, 1942. [Class 38 (ii)] To increase the tuning range at high frequencies of an inductance coil or inter-valve coupling transformer of the movable magnetic core type, the winding or windings are subdivided into a number of parallel-connected coils A, B, C, either coaxially disposed end-to-end, Fig. 1, or co-extensive but connected together only at the ends, Fig. 2. Specifications 429,826, [Group XXXVI], and 463,724 are referred to.
