Abstract

553,998. Electromagnetic interrupters. STERN, W. Jan. 13, 1942, No. 482. [Class 38 (v)] In an electromagnetic interrupter for controlling an intermittent signal 7, energization of the coil 1 from a source 5,6 through a resistance 3 operates contacts 2 so as to introduce a resistance 4 in parallel with the coil 1. The consequent partial de-energization of the coil 1 then releases the armature so that contacts 2 return, whereupon coil 1 is again fully re-energized and the cycle is repeated. In modifications, the signal 7 is placed in series or parallel with the coil 1.
