Title: Combination sound and picture device
IPC: G03B31/00
Filed: 1945-07-16
Abstract: 596,036. Combination sound and picture devices. LIKE, R. M. July 16, 1945, No. 18142. [Class 40 (ii)] [Also in Group XX] In a combined sound and picture reproducing device, a stationary shallow circular case 7 contains the rolls of film 23, 24, Fig. 2, the shutter-mechanism and the film-feeding mechanism, and has a window 49, Fig. 3, in the curved edge 9, past which the film is moved. A rotating centre part 17, driven by a shaft 114, drives the mechanism by means of flange 16 and toothed ring 20, and may carry a sound record disc 6 for reproduction by a gramophone pick-up. An optical sound-gate 206, Fig. 5 (not shown) is provided in the said curved edge 9 of the case 7, for use where a sound track exists on the film. The film is endless and is driven by a sprocket 21, Fig. 2, on the centre part 17, the film passing from the inner part of roll 23 to the inner part of roll 24 via wheels 31, 32. The toothed ring 20 engages a rotating member comprising a cam 62, Fig. 2, and shutter 61. The cam 62 imparts the necessary motion to a member 68 to feed the film past the window 49, while the shutter during the intermittent movements of the film interrupts the passage of light which comes from a source 108, Fig. 3, below the case 7 and is reflected by a prism 53 through the film to a picture projection objective 101. Automatic stopping, and synchronization when a sound-disc is used, is effected by providing a notch 200, Fig. 7, at the starting position in the film, into which a roller 400 on a switch lever 201 may drop. After closing the main switch 210, the motor 231 may be started by a press switch 221-223 which closes a circuit through a solenoid 216 which operates the contact lever 227 and closes the motor circuit. Almost immediately the switch lever 201 is lifted by the moving film and causes the circuit through the solenoid 216 to be broken, and at the same time causes a circuit through a "hold-on" solenoid 215 to be made. When the notch 200 in the film again reaches the roller 400, the circuit through the "hold-on" solenoid 215 will be broken and the circuit to the motor will be automatically broken. Should the apparatus be switched off before the end, restarting may be effected by the use of press switch 222-224, which will close the circuit of coil 216 and effect closing of the switch lever 227 to start the motor, which will automatically stop again when the notch 200 reaches the roller 400.

Title: Improvements in ward leonard and like electrical systems
IPC: H02P7/34
Filed: 1935-06-26
Abstract: 459,052. Control of D.C. motors. ENGLISH ELECTRIC CO., Ltd., 28, Kingsway, London, and WILSON, J. C., Uplands, Brocton, Staffordshire. June 26, 1935, No. 18269. [Class 38 (iii)] Varying E.M.F.; regenerative braking.-In a Ward-Leonard or like system, means operating in response to a predetermined reverse power, effect a weakening of the motor excitation when the latter is regenerating, and means are provided for restoring the excitation to normal only after a predetermined definite delay. A generator 1, field-controlled by a regulator 10 supplies a ship-propulsion motor 3, and a reverse power relay, having a series coil 7 and a moving voltage coil 8, operates when a predetermined reverse power is attained to close contacts 6 thereby short-circuiting the coil of a control relay 12 which opens its contacts to de-energize a relay 13 which de-energizes a relay 14. The de-energization of the relay 14 inserts resistance 5 in the circuit of the motor field 4 and also opens contacts 15 so that the relay 12 is again energized. Thus, the relay 13 is re-energized but closes its contacts, to reenergize the relay 14 and restore the excitation, only after a time delay provided by a dashpot 18. If the regenerated power still exceeds that necessary to retain the contacts 6 closed, the cycle of operations is continued. The coils of the reverse-power relay oppose during power operation but assist during regeneration. In a modification, Fig. 2 (not shown), the reverse power relay actuates contacts which open to insert the resistance 5 when the predetermined regenerative power is attained, and reclose with a time delay under dashpot control when the regenerated power is reduced. In a further modification, Fig. 3 (not shown), the reverse power relay has an additional coil assisting the series coil during regeneration, but shortcircuited by the contacts of the relay until the latter is operated by excess regenerative power. Thus, the reverse power must fall to a value less than that at which the relay operated, or may even have to reverse before the motor excitation is restored. A dashpot may also be provided to give a time delay. The additional relay coil may be supplied from a separate source or it may be connected across an adjustable portion of the resistance 5 inserted in the motor field circuit by operation of the reverse power relay. The resistance 5 may be inserted in the field circuit of an exciter for the motor field instead of in the motor field circuit itself.
