Abstract

457,263. Inductances. BOSCH AKT.- GES., R., 4, Militõrstrasse, Stuttgart, Germany. June 24, 1936, No. 17551. Convention date, June 24, 1935. [Class 37] In a multiple inductance coil for tuning a plurality of oscillatory circuits, the inductance of individual coils a, b being adjusted by screw cores g, f in a common carrier c, one at least of the cores is made hollow to permit of screw-driver access to the next. The cores are secured in adjusted position by molten material h which hardens on cooling.
