Abstract

1529889 Automatic control ZAKLADY MECHANICZNE IM GEN KAROLA SWIERCZEWSKIEGO 2 April 1976 [22 April 1975] 13531/76 Heading G3N A double-acting linear actuator 2, 3 is positioned by directing hydraulic fluid to the actuator by a pump 1 driven by a variable speed reversible motor 4 responsive to a comparison in a device 5 between a command signal 1 and a feedback signal 7. The device 5 employs SCR's to determine direction of motor rotation.
