Title: Improvements in and relating to electric motor control systems
Inventor: PETCH THOMAS HAYES
IPC: B66B1/06
Filed: 1956-02-02
Abstract: 798,654. Control of D.C. motors. BRITISH THOMSON-HOUSTON CO., Ltd. Jan. 29, 1957 [Feb. 2, 1956], No. 3338/56. Class 38 (3). The armature 1 of a D.C. motor having a field winding 6 is supplied through a mercury arc rectifier 2. Movement of a master controller MC into its forward range establishes a circuit for relay FDC whereby contactor F is closed to energize the field winding 6 in the appropriate direction. The rectifier is rendered conducting by the movement of contact finger 16, so as to apply a low voltage to the motor. As the motor commences to rotate a motordriven directional switch DS closes contacts FDSI to complete a hold-in circuit for the relay FDC. The motor torque and speed may then be controlled by adjustment of the position of the master controller. To obtain braking, the master controller is returned through its " off " position into the reverse range of movement. The output of the rectifier is initially reduced to zero, and, when the controller reaches the reverse position, a relay RC is energized to insert resistor 5 in the motor armature circuit. At the same time, the contactor F is opened and the motor field winding is de-energized. The relay RC also closes contacts to complete a circuit for the reverse contactor R whereby the motor is excited in the reverse direction. The braking torque is then increased by further movement of the controller away from the " off " position. Similar operation is obtained when the motor is started in reverse. In a modification, the field winding 6 is excited by an amplidyne having a control winding which is energized through normally-closed contacts of the relay RC, Fig. 2 (not shown). The master controller includes a further rheostat providing an alternative circuit for the exciter control winding when the relay RC is energized. This alternative circuit is open in the " off " position of the controller, but is closed and the resistance progressively reduced when the controller is moved away from the neutral position. The relay RC is also provided with normally-open contacts for short-circuiting the rheostat 11 to afford maximum rectifier output. In place of grid control of the rectifier, tap-changing means may be provided, or saturable reactors may be used for regulating the alternating voltage applied to the rectifier. The motor may drive a mine winder, and manual actuation of the master controller may be replaced by automatic control of the closed-loop type.

Abstract: 316,896. Dunlop Rubber Co., Ltd., Willshaw, H., Smith, H., and Broadbent, F. G. Feb. 3, 1928. Moulding indiarubber and wheel tyres.-Relates to apparatus for moulding and vulcanizing pneumatic tyres, tubes and other rubber articles under internal pressure and wherein automatic means are provided to open or close the apparatus, and consists in means for preventing opening of the apparatus until the internal pressure is released. The invention is described in connection with an hydraulic press associated with electrical timing and recording devices similar to those described in Specification 303,075. The platen press 1, Fig. 8, is fitted with an hydraulic valve adapted to be opened by a hand and foot lever 36 against the action of a spring 37. To prevent accidental opening of the press, a pair of pivoted props 28, 29, are swung under the platen 3<a> as the press closes. The props are coupled to a shaft 32, Fig. 5, which is operated from the lever 36 through links 40, shaft 38, levers 41 and a resilient connection 42. A spring 46 assists the inward movement. The prop 28 carries a trip device comprising a plunger 22, Fig. 3, furnished with a roller end 22<a> mounted within a solenoid 24 and normally pressed outwardly by a spring 25. As the prop 28 moves inwardly, the roller 22a engages a lever 27, Fig. 8, to open the air valve 4 and admit compressed air to the airbag 53. The spindle 47, Fig. 4, of the hydraulic valve is locked in the " on " position by a plunger 50 engaging a cam projection 49. Compressed air admitted through the valve 4 projects the piston 50 against the action of a spring 52. Closing of the press by operation of the lever 36 actuates a switch to set into operation the electrical timing mechanism. After the predetermined interval, the solenoid 24 is energized to withdraw the plunger 22 and free the lever 27 which, under spring pressure, turns to open the valve 4 to exhaust. The air pipe connections are so arranged that the pressure on the piston 50 is last relieved, following which the spindle 47 turns under the influence of the spring 37 to relieve the hydraulic pressure and permit the press to open.
