Abstract

468,763. Transformers. GALVIN MANUFACTURING CORPORATION. Jan. 10, 1936, No. 881. Convention date, Jan. 10, 1935. [Class 38 (ii)] [Also in Group XL] In a high-frequency transformer used for balancing out ignition interference on aeroplanes &c., each coil 15, 16 is in the form of a double helix, Fig. 4, compressed to a flat double layer, the coil 16 being mounted on geared screws 49, 50 so that the coupling may be varied. The coils are separated by an electrostatic screen 17 consisting of a comblike member, Fig. 10, the teeth 54 being connected at one end and twisted at an angle of about 45‹.
