Filed: 1968-03-25
Abstract: 1,205,335. Automatic control of speed. ZENTRALLABORATORIUM FœR RUNDFUNKUND FERNSEHEMP-FANGSTECHNIK. March 25, 1968, No. 14246/68. Heading G3R. [Also in Division H2] The speed of an asynchronous motor e.g. in a record player is maintained substantially constant by supplying it with a voltage having A.C. and D.C. components, their ratio being controlled by a signal dependent on the actual motor speed or the supply voltage. The motor windings 11, 12 are supplied via a transistor 7 and an oppositely poled diode 8, so that the half cycles passed by the transistor are reduced according to the conductance of the transistor. As shown, this is regulated by the voltage from a tachogenerator 6, but in Fig. 4 (not shown) a pair of auxiliary windings (13, 14) detect fluctuations in the supply voltage, which are "amplified" by a Zener diode and vary the current through resistor (20) connected between emitter and base of the transistor, thereby varying its conductance. The speed is selected by switched resistor 9, 10 (or 15, 16).

Title: Improvements in or relating to electric power systems
IPC: B63H23/24
Filed: 1935-05-16
Abstract: 458,508. Automatic control systems. WESTINGHOUSE ELECTRIC & MANUFACTURING CO., East Pittsburg, U.S.A.- (Assignees of Schaelchlin, W. ; 305, Woodside Road, and Forbes, A. D. ; 911, South Avenue, both in Wilkinsburg, Pennsylvania, U.S.A.) May 16, 1935, No. 14344. Convention date, May 19, 1934. [Class 38 (iv)] An arrangement for automatically controlling the stability of transmission between a variable speed alternator 2 and a work motor 5 comprises an excitation control for one or both of the machines including a spring balanced control member 24 which is acted on by two electromagnets 18, 19 in opposition, the electromagnets being responsive respectively to the excitation of one or both of the machines and to the speed of one of them. The turbine driven alternator 2 of a ship propulsion system is connected to a synchronous motor 5 through a reversing switch. The excitations of the alternator and motor are supplied from a generator 4 through control resistances 7, 8 and the total excitation current is passed through the electromagnet coil 19 of the relay 14. Coil 18 is energized from a tachometer generator 12 on the motor drive shaft. The balance arm 24 is arranged to engage one of two contacts 25 on a variation in stability as measured by the ratio of the excitation current to the motor speed and to energize a reversible motor 9 to vary the excitation of both machines in the appropriate sense. In a modification applied to an induction motor drive, the coil 19 is responsive to the excitation current of the alternator and the coil 18 to the speed of the alternator. The Specification as open to inspection under Sect. 91 disclosed an arrangement in which the relay device 14 is a dynamometer instrument having two coils, one fixed and one movable with the balance arm on each end of the arm. The coils at one end are energized by the exciter voltage and the rectified voltage of the alternator so as to produce an effect responsive to the alternator voltage and those at the other end are connected in series with each other either across a tachometer generator on the motor or alternator shaft or across one phase of the motor input through an inductance. In the former case the effect opposing that of the alternator voltage is dependent upon the square of the motor speed and in the latter case it is stated to be responsive to the square of the flux in the machines. This subject-matter does not appear in the Specification as accepted.

Filed: 1928-05-18
Abstract: 311,564. Mackie & Sons, Ltd., J., and Mackie, J.. P. May 18, 1928. Coilers. - In an arrangement for delivering sliver into a can a reciprocated on a carriage, the sliver passes between the delivery rollers g<1>, g<2> down a plate h to a pair of rollers k<1>, k <2> arranged above the can. These rollers turn inwardly at a rate slower than that of the delivery rollers and are a distance apart less than the width of the sliver. The sliver is thereby arranged in zig-zag fashion on the plate h before falling between the rollers into the can. Additional rollers o<1>, o<2> may be arranged outside the rollers k<1>, k<2> to act as compressors when the can is filled. The rollers are driven from the delivery roller shaft r by bevel gearing, a chain t, and a shaft l. While an empty can is being substituted for a full one a hood p pivoted on a rod q is turned down on to the plate h to hold the sliver. The substitution of the cans may be made by hand or automatically by means such as are described in Specification 311,556.
