Abstract
407,166. Inductances. ARDENNE, M. VON, 19, Jungfernstieg, Lichterfelde, Berlin. Jan. 13, 1933, No. 1163. Convention date, Jan. 14, 1932. [Class 37.] Chokes D located inside thermionic valves have a non-uniform helical pitch and are tuned by varying their spring tension (and therefore their length) by means of eddy-current heating, or by manipulation through an aperture.
