Abstract

379,206. Wireless receiving apparatus. IDEAL WERKE AKT.-GES. FUR DRAHTLOSE TELEPHONIE, 97, Grosse Leegestrasse, Hohensch÷nhausen, Berlin. Jan. 12, 1932, No. 942. Convention date, Feb. 24, 1931. [Class 40 (v).] A coil assembly for a wireless receiver operating on two wave-bands comprises two separate primary and secondary windings respectively inductively coupled which are arranged to be connected in parallel when receiving on the shorter wave band. The Figure shows secondary coils 1, 2, and primary coils 5, 6 and the switches 7, 8 for changing the wave-band.
