Abstract

467,862. Inductances; coupling coils. COLE, Ltd., E. K., and ROWE, H. C. March 2, 1936, No. 6203. [Class 38 (ii)] The mutual inductance between a pair of coils or two parts of the same coil 1, 2 is rendered adjustable by mounting them on formers 3, 4 keyed together by pins 7 and having central holes provided with screw threads of different pitch engaged by a differential screw 8.
