Title: Improvements in or relating to circuit arrangements for separation of line and frame synchronising signals in a television receiver
IPC: H04N5/10
Filed: 1942-02-20
Abstract: 555,492. Television synchronization ; relaxation oscillators. STANDARD TELEPHONES & CABLES, Ltd., CHATTERJEA, P. K., and AMBROSE, D. M. Feb. 20, 1942, No. 2276. [Classes 40 (iii) and 40 (v)] A circuit arrangement for synchronizing a television receiver with the transmitter comprises two separate synchronizing paths to each of which the composite signal is applied, each adapted to pass the line and frame frequencies respectively and each including a relaxation oscillator having a circuit tuned to the corresponding scanning frequency or a harmonic thereof connected in series with the grid circuit of the valve which generates the oscillations. In the arrangement shown, the television signal, after demodulation from a carrier if the transmission is by a carrier, is applied to the terminals 1, 2 connected to two separate synchronizing paths. One synchronizing path includes a resistance 9 in series with a condenser 19 tuned to line frequency or a harmonic thereof, a transformer 16 having a secondary tuned to line frequency by a condenser 17, and a relaxation oscillating valve 10 having its grid connected to the secondary of the transformer. The anode of the valve is fed with HT through a resistance 13 ; the grid is biased by a potentiometer 14 across a condenser 15 ; and the relaxation oscillation circuit includes the resistance 12 and the condenser 11 which yields saw-tooth oscillations at line frequency at the terminals 3, 4. The other synchronizing path includes an amplifying valve 30 to the grid of which the signal is fed by means of resistances 31, 36, and a relaxation oscillator 20 coupled to the amplifying valve 30 by a transformer 26 having both primary and secondary tuned to frame frequency, so that saw-tooth oscillations at that frequency are delivered by the terminals 5, 6. The picture reproducing channel is fed from terminals 7, 8 connected to terminals 1, 2.

Abstract: 1410710 Mechanical switches INDUSTRIE PIRELLI SpA 17 Jan 1973 [18 Jan 1972] 2352/73 Heading H1N [Also in Division B3] A copying device for a milling machine comprises a template 4 fixed relative to the workpiece 1, and a sensor 5 arranged via a two part electrical circuit A, B, Fig. 3, to cause the movement of the tool head in the X, Y, directions to cut a profile 2, so that when the sensor is in engagement with the template the tool head is moved in one of the directions under the control of one part of the electrical circuit, and when they are not in engagement, the movement of the tool head in the other direction comes under the sole, or additional, control of the other part. Sensor 5, Fig. 2, comprises a disc-shaped stylus 6 carried on a spindle 7 mounted in a housing 8 by a spherical bearing 9. A spring- urged-plate 12 is located on the spindle by a ball 11 and the plate forms the moving contact of a switch, whose fixed contacts are formed by adjustable screws 18, 19. In operation, stylus 6, Fig. 4 is required to move from point P to point P1. Stylus 6 is pressed against the template on the Y axis so that spindle 7 oscillates around bearing 9 and plate 12 touches screw 18 and closes circuit A, Fig. 3. An electro-clutch 22 is energized and the tool head is moved a distance L1X along the X axis. At the end of this distance the stylus is not in contact with the template, spindle 7 oscillates and plate 12 moves into contact with screw 19, and the part B of the circuit is closed. A second clutch 23 is energized and the tool head 3 is moved a distance L1Y along the Y axis. This stepping operation is carried out until the stylus reaches point P1. In a modification, at the beginning of the operation part A of the circuit is short circuited, so that clutch 22 allows head 3 to move continuously along distance L1X, whereupon plate 12 contacts screw 19 which closes circuit B and actuates clutch 23. However unlike the first sequence at this stage, circuit A does not open since it is short circuited. The stylus moves along line (L2), Fig. 5 (not shown), resulting from simultaneous feeds L2X and L2Y. This sequence continues until the stylus reaches point (Q) whereupon part B of the circuit is short-circuited and part A is re-established. The sequence continues up to point P1. Capacitors or diodes 24, 25, and indicator lamps 26, 27, are placed in circuits A. B.
