Abstract

526,107. Control of motors between limits; wireless transmitting apparatus. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and APPLETON, W. A. Feb. 8, 1939, No. 4197. [Class 38 (iii)] [Also in Group XL] An electric motor 2 moving a current or voltage regulating device to a maximum or minimum position, e.g., the tuner of a transmitting aerial, is automatically stopped when the rate of change of current through the device becomes zero. The motor is started by closing switch 1, thereafter a pick-up from the aerial is rectified by a diode 5 and impressed directly upon a relay coil 6 and through a condenser 8 and triode 12 upon another relay coil 13. The contacts of relay 13 close and those of relay 6 open, and. when the maximum or minimum position is reached the contacts of relay 13 open and stop the motor.
