Abstract
406,203. Inductance coils. VOGT, H., 10, Garystrasse, Dahlem, Berlin. July 31,1933, No. 21451. Convention date, Sept. 21, 1932. [Class 37.] A high-frequency inductance coil with magnet core has a coupling winding the position of which is variably in respect to the magnetic flux. In the example, Fig. 1, such windings 5 on rotatable armatures 6 are shown as being fitted in bores 3, 4 in the core 1 while Fig. 4 shows a winding 20 movable into or out of a gap 23 in the core.
