Title: Improvements in and relating to methods of measuring speed variations
IPC: G03B27/46
Filed: 1931-06-23
Abstract: 383,302. Measuring speed variations of apparatus such as sound recording or reproducing apparatus. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Mead, M. S. ; 1410, Regent Street, Schenectady, New York, U.S.A.) June 23, 1931, No. 18168. Convention date, June 23, 1930. [Class 40 (ii).] Comprises means for measuring, as for testing purposes, the speed variations of a rotatable member, particularly applicable to sound recording or reproducing apparatus, wherein electrical impulses are produced whose frequency varies with the speed of the member and the frequency variations are converted into amplitude variations which are measured. As shown applied to apparatus for reproducing pictures and sound from a film record, the film is passed at the sound head over a drum 4 where a beam of light is modulated by the sound record and impinges upon a photoelectric cell 6. For measuring the speed variations, a special sound-record film is used having a constant frequency note recorded thereon. Any variations in speed of the film give rise to proportionate changes in the frequency of the impulses generated by the photo-electric cell 6. The output from the cell 6 is passed through an amplifier 8 and adjustable resistance ,15 to the primary of a transformer 14. Across the secondary of the transformer 14 is connected a variable condenser 16 adjusted to tune the circuit to a frequency slightly different from that of the impulses recorded on the film. By this means the frequency variations are converted into variations of amplitude which are rectified and amplified by thermionic valves 17, 18 respectively. The output from the amplifier 18 is connected through a condenser 20 and resistance 21 to the heating coil 22 of a thermoelectric generator 23 whose output actuates a milliameter 24. In this way variations in speed of the film driving mechanism are registered by the milliameter 24. The milliameter and thermo-electric generator may be replaced by an oscillograph. When measuring speed variations of a gramophone turntable a disc record having a constant frequency note recorded thereon is employed in conjunction with an electric pick-up which delivers current impulses to the amplifier 8. Reference has been directed by the Comptroller to Specifications 7022 /03, [Class 106, Registering &c.], 152,128 and 279,665, [both in Class 106 (iii), Fares &c.].

Title: Thermostatically operated time delay switches
IPC: B60Q1/38
Filed: 1955-06-24
Abstract: 803,588. Switching systems. HOLLINS, J. R. June 24, 1955 [July 19, 1954], No. 18308/55. Class 38 (4). [Also in Groups XXXVII and XXXVIII] A direction signalling system for motor vehicles comprises a selector switch which is automatically restored to neutral, after a preset time interval, by thermostatic control means in which the operation of the control means may be delayed in response to operation of a control pedal of the vehicle. An insulating base-plate 11 carries a selector lever 15 pivoted at 12 and biased to the neutral position shown by a spring 16. A conductive strip 20 serves to connect the battery 26 via flasher 25 selectively to left or right signal lamps LF, LR or RF, RR. The lever 15 is latched in its operated position by a notch 34 in a conductive latch plate 30 which engages with the respective upturned end 36 or 36<SP>1</SP> of spring 35 or 35<SP>1</SP>. The springs 35, 35<SP>1</SP> are biased outwardly to free the latch plate 30 but are constrained to their latching position by high resistance wires 40, 40<SP>1</SP> respectively. Bimetallic strips 43, 43<SP>1</SP> are arranged as shown, with heater coils 47, 47<SP>1</SP> connected to respective springs 35, 35<SP>1</SP> and earthed via stop lamps SL. If, for example, the lever 15 is moved counter-clockwise the appropriate signalling lamps are flashed, the plate 30 engages spring 35 to latch the lever 15, and the circuit of heater coil 47 is completed. The lamps SL are not illuminated due to high resistance of coil 47. After a preset interval strip 43 bends to engage contact 42 and complete a circuit through wire 40 which after a further interval expands to allow spring 35 to move out of the notch 34 in plate 30, thereby releasing the lever 15 which immediately restores to its neutral position under action of spring 16. Should it be desirable to extend the time interval before restoration of the device this is effected by short-circuiting the heater winding 47 (or 47<SP>1</SP>) which does not heat up to initiate the release process until the short is removed. For example, in the circuit shown, the heater winding is shorted by the brake pedal switch BPS if the vehicle is stationary while waiting to make an indicated turn and thus the turn signal remains effective until after the vehicle has been in motion for the preset interval. A simplified embodiment utilizing a push-button operated latching switch (Fig. 3, not shown), is described for general application, and this is provided with a further push-button for short-circuiting the heater winding to prolong the restoration delay time as required.
