Abstract

176,126. Igranic Electric Co., Ltd., (Cutler-Hammer Manufacturing Co.). Nov. 30, 1920. Alternating-current relays are provided with a resistance connected in parallel with the magnet winding for the purpose of making the response of the relay dependent upon the frequency of the current. In a modification shown in Fig. 2, the relay winding 4 is provided, in addition to the resistance 6, with a direct current winding 13 in order to make the response take place during a pulsation of given sign.
