Title: Improvements in apparatus for processing elastomeric material
IPC: B29C48/06
Filed: 1959-04-20
Abstract: 870,176. Moulding rubber sheet. UNITED STATES RUBBER CO. April 20, 1959 [June 13, 1958], No. 13348/59. Class 87(2). Apparatus for processing, i.e. consolidating, vulcanizing, moulding and embossing, elastomeric material includes an inlet drum rotatable about its axis for supporting elastomeric material ; an outer ring of larger diameter than and surrounding the drum ; and means for developing an area of pressure between the drum and the ring and for effecting a relative rolling movement between the drum and ring to cause a continuous displacement of the area of pressure. Rubber is fed e.g. from an extruder 40, Fig. 2a, on to an anti-clockwise-rotating, oil-heated drum 10 within an outer ring 16 heated by electrical windings (not shown) and pressed against the drum by wheels 19 riding in tracks 20 on the ring, which wheels are actuated by a pair of hydraulic cylinders 17 rotatably mounted on the contral shaft 13; the rotation of the drum 10 and the contrarotation of the wheels 19 are balanced to maintain the aperture 16a of the ring stationary with respect to angular rotation. To counteract the effect of possible variations in the thickness of the stock entering, automatic centrol may be employed to speed up or to slow down the rotation of the cylinders 17, based upon variations in the angular displacement of the ring 16. Stops (not shown) may be employed in the cylinders 17 to prevent the pistons 18 from moving beyond pre-determined points to establish a pre-determined gauge for the rubber being processed. The apparatus may be adapted for coating wire with rubber and vulcanizing the rubber by the provision of complementary slots on the drum and ring, Figs. 4 and 4a (not shown). A ring 56 of gradually varying thickness with a circular outer periphery and a non-circular inner periphery, Fig. 5, may be used for the simultaneous controlled blowing and curing of sponge rubber and other expandable stocks. Specification 781,999 is referred to.

Title: Improvements in or relating to control apparatus for electric motors
IPC: H02P7/30
Filed: 1954-05-07
Abstract: 757,646. Control of A.C. motors. GENERAL ELECTRIC CO., Ltd., and PARTON, K. C. May 6, 1955 [May 7, 1954], No. 13408/54. Class 38(3) The magnitude of the secondary resistance 1 of an induction motor is adjusted by means of solenoid 2 which operates in opposition to spring 3 so that the magnitude of the resistance is reduced with increase of excitation of the solenoid. A tachometer generator 6 is coupled to the shaft of the induction motor and is connected to a bridge rectifier 9 for energizing the control winding 14 of a magnetic amplifier 15 having an A.C. winding 16 in series with the winding of the solenoid 2. Switches 10, 11, are adapted to isolate the control winding 14 from the tachometer generator during reverse-current braking operation of the induction motor. During motoring operation in either direction, however, or during dynamic braking operation, the excitation of the winding 14 is dependent upon the speed of the induction motor. The magnetic amplifier has a biasing winding 19 which opposes the winding 14 and is effective only during dynamic braking operation so that the windings 14, 19, are substantially balanced at the maximum speed of the induction motor. Thus, during motoring, the excitation of the solenoid 2 is a function of the motor speed and during dynamic braking is a function of the slip since increase in the excitation of the solenoid leads to decrease of the magnitude of the resistance 1, this resistance becomes a function of the slip during driving, and of the speed for dynamic braking. The winding 16 is shunted by a variable resistance 21 connected in series with transformer 22. The variable resistance is used as a speed or torque control means for the induction motor and the transformer is arranged to control the characteristics of the current fed to the solenoid 2 so that appropriate rotor resistance-speed curves are obtained. When the induction motor is braked regeneratively, the magnetic amplifier will maintain the resistance 1 at a minimum value. In a modification, the excitation of the magnetic amplifier is dependent upon the difference between a fixed bias and a quantity varying with the speed during motoring, and dependent upon the speed during dynamic braking. In this case, the circuit elements 21, 22 are connected in parallel with the winding of the solenoid 2, and the resistance 1 is arranged to increase with increase of the degree of saturation of the magnetic amplifier.
