Abstract: 793,026. Control of A.C. motors; fluid actuation of switches. GENERAL CONTROLS CO. April 30, 1956, No. 13163/56. Classes 38 (3) and 38 (5). A load-carrying piston 16 is moved upwardly by means of a spring 18, and is forced downwardly by fluid under pressure which is delivered to the top of the piston through the agency of a pump 19 driven by an A.C. motor 20. The pressure in the piston space is relieved by means of an electromagnetically operated valve 34, 35, the coil 40 of which is connected in series with the D.C. control winding 51 of a saturable reactor 49. The A.C. windings of the reactor are connected in series with the motor, and the arrangement is such that the control current affording initial closure of the relief valve is less than that necessary to reduce the reactance of the windings 47, 48 sufficiently for operation of the motor. An intermediate position of the piston 16 may be obtained by closing the relief valve when the piston is moving upwardly, or by de-energizing the motor when the piston is being lowered, and with the relief valve closed. The upper limit of movement of the piston is defined by means of a flange 17a on cap 17, and, when the piston reaches its lower limit, a switch 46 is actuated to stop the motor. The limit switch comprises an arm 51 which is angularly positioned in accordance with the position of the piston-stem 10, and which carries a movable contact 52 co-operating with a resiliently-mounted contact 53.
