Abstract
902,985. Measuring electrically. LOEWY ENGINEERING CO. Ltd. July 22, 1960, No. 25705/60. Class 40 (1). [Also in Group XXIX] In an hydraulic press installation the flow of fluid to the press cylinder 11 is controlled by valve 31 in accordance with the position of the rotor of a differential selsyn receiver 24 responsive to the difference in rotor positions of a selsyn transmitter 13 driven by the press ram 10 and a selsyn transmitter 16 manually controlled. An alternative manually-controlled transmitter 20 may be switched into circuit to replace transmitter 16 so that one transmitter controls the upward movement and the second transmitter the downward movement of the press ram. In order to obtain greater sensitivity when the press ram is close to its required position, a second differential selsyn receiver 35 may be switched in place of receiver 24, the second receiver being connected by gearing to the first receiver, and hence the hydraulic fluid control valve, so that a greater torque is developed to operate the valve.
