Abstract
424,400. Detecting faults. DUTSCHKE, K., 6, Schluesselfelderstrasse, Nuremberg, Germany. July 31, 1934, No. 22288. Convention date, Oct. 20, 1933. [Class 37] An electromagnet for testing motor armatures comprises a magnetizing coil a mounted on a U-shaped core 2 rounded off at its free ends 3 to form a support for the armature to be tested, an interrupter b being mounted inside the frame or body 1 carrying the magnet. The device may be used on either direct or alternating currents.
