Aug. 31, 1931, No. 24397. [Class 35.] Exciting.-The rotor windings of a synchronous motor are arranged in two phases, one comprising an exciting winding B connected through a resistance R to a source of potential D, and the other a starting winding C so arranged in relation to a solid iron core or cores or connected in series with a resistance K so arranged in relation to a solid iron core k<1> that the losses in the winding or in the resistance connected in series therewith varv with the rotor frequency. The motor is started as an induction motor having a two phase rotor with a starting resistance in circuit with the phase B, and the apparent resistance of the winding C is high at starting as the result of eddy currents induced in the solid iron core. The core k<1> may rotate with the rotor or it may be in the base of the machine or elsewhere and the winding K connected to the phase C through slip-rings. In a modification, a solid iron mass of U-section is fitted to the rotor and end connectors of the phase C pass through the mass or are wound on it. During synchronous operation of the motor, the starting winding acts as a damping winding.

Abstract: 653,778. Saw-tooth generating circuits. COURT, P. R. J., and PYE, Ltd. Sept. 17, 1948, No. 24407. [Class 40 (vi)] In an electromagnetic scanning circuit for a cathode-ray tube the amplitude of the scan is varied by means of a variable inductor connected in series with the deflecting coils. The Figure shows a scanning circuit in which the deflecting coils L3, L4 are fed via an output transformer T1 and in which the variable inductor L1 connected in series with the deflecting coils enables the amplitude of the scan to be varied. The variable inductor L2 connected in parallel with part of the secondary winding of transformer T1 has the reverse effect of inductor L1, i.e., by decreasing its impedance the amplitude of scan is decreased. Inductors L1, L2 preferably have a common dust-core which as it moves into one inductor is extracted from the other so that by this means the amplitude of scan can be varied whilst maintaining constant impedance of the circuit viewed from transformer T1. The efficiency and linearity of the scanning circuit is improved by a diode V2 connected across the deflecting coils. The network R1, C2 may be connected as shown across inductor Ll to prevent " ringing ". In a modification, Fig. 3 (not shown), the second variable inductor is connected across the whole of the secondary winding of the output transformer. In a further modification, Fig. 2 (not shown), the deflecting coils and series inductor are fed from a tapping on the output transformer and the second variable inductor is connected between this tapping and one end of the secondary winding.

Abstract: 1497960 Fluid coupling control VOITH TURBO KG 14 June 1976 [27 June 1975] 24507/76 Heading F2W A hydrodynamic coupling comprising an impeller 11 and a drive runner 21 defining a working space, and a fluid control circuit for supplying working fluid to the working space and for discharging the working fluid therefrom is provided with a device for controlling the degree of filling of the working space by variation of the discharge rate of the working fluid from the working space, the device being adjusted by means of an actuator which is driven in a stepwise manner when the coupling is started-up. As shown, the control device is in the form of a scoop-tube 40 which is adjustably movable by a piston-cylinder arrangement 42, 43 towards or away from a fluid compartment 15 connected by ports 14 to the working space. In operation, when a pump 31 is actuated to initiate supply of working fluid from a pump 30 to the working space, a valve 33 is closed so that some of the working fluid is directed by way of a duct 7 to the cylinder 42 and a build-up of fluid pressure on the piston 43 in opposition to a return spring 44 initiates movement of the scoop tube 40 away from the compartment 15. A series of ports which are spaced axially of the cylinder in the side wall thereof are so located and connected by way of adjustable restrictors 8a, 8b, 8c to the duct 7 that the speed of retraction of the scoop-tube 40 is arranged to progressively increase in such a manner as to maintain substantially constant the torque transmitted by the coupling from an input shaft 10 to an output 20 during start-up of the coupling. In an alternative embodiment (Fig. 4, not shown), in which an electric motor (56) drives the input shaft 10, an adjustable regulator (60) is connected by way of a transformer (58) to the input leads (57) of the motor 56 so that during start-up of the coupling, a solenoid operated valve (52) is actuated by the regulator (60) in the event that input current to the motor (56) exceeds a pre-determined value, thereby temporarily to curtail movement of the scoop-tube 40 in a direction away from the compartment 15 until the current drops to the predetermined value. By providing an additional solenoid operated valve (55) controlled by the regulator (60) and arranged between the sump (30) and the duct 7, the movement of the scoop tube can be reversed and not just curtailed in the event the current to the motor (56) exceeds the predetermined value.
