Title: Improvements in or relating to synchronising separator circuits
Inventor: COPE JOHN EDWARD
IPC: H04N5/08
Filed: 1955-01-05
Abstract: 797,947. Television. PYE, Ltd. Jan. 5, 1956 [Jan. 5, 1955], No. 323/55. Class 40 (3). A circuit for separating positive-going synchronizing pulses from the video component of a television waveform comprises a pentode VI, followed by a buffer stage in the form of a triode V2, the pentode being operated conventionally with a low screen potential, so as to conduct only over a small part of the grid signal corresponding to the synchronizing pulses, and the triode presenting a high input impedance so that the pentode anode load R3 may be given a large value (some 5-10 times normal). By this means, clipping of the synchronizing pulse tips is produced by the knee of the anode characteristic but the bandwidth of the circuit remains sufficient to ensure adequate reproduction of frame pulses. The grid signal is restored by the action of capacitor C1 and resistor R2. Differentiated synchronizing pulses suitable for use in an automatic frequency control circuit of a flywheel synchronizing circuit are obtained from a transformer T in the anqde circuit of the triode V2, whilst frame pulses are separated from the combined pulse train appearing across the cathode load R4 by means of a separator circuit FS, including diodes D1, D2. In a first modification, Fig. 2 (not shown), the cathode resistor R4 is by-passed by a capacitor so that the triode cuts-off during line synchronizing pulses, the cathode circuit may then function in place of the first stage of the frame separator FS, diode D1 being omitted. With this arrangement, the output of diode D2 may be differentiated to emphasize the first frame pulse and improve operation in the presence of noise pulses. In a second modification, Fig. 3 (not shown), the grid of the pentode is D.C., coupled from the cathode of the video output valve, the cathode including a C.R. circuit which charges to synchronizing pulse tip to provide the separator action. In a third modification, Fig. 4 (not shown), the grid of the pentode is returned to a positive potential via a high value resistor so that the anode is almost at each potential when the valve conducts. This low potential is employed to cut-off the triode so that, in operation, the valves conduct alternately. The arrangement prevents selfoscillation of the circuit, particularly where the pentode and triode share a common envelope and the triode anode pin and pentode grid pin are adjacent.

Filed: 1941-01-09
Abstract: 549,043. Making paper &c. tubes. STANDARD TELEPHONES & CABLES, Ltd., and LEE, E. C. Jan. 9, 1941, No. 351. [Class 99 (ii)] [Also in Group XXXVI] An electrically insulating body is formed by winding a strip of paper or other fibrous material coated with polystyrene upon a mandrel, by passing the strip 58 between the mandrel 45 and a pressure roller 31 so that the coating is extruded to form a continuous ridge 57 which prevents the entry of air between the layers of fibrous material. Fig. 3 shows a machine in which the paper &c. is led from a supply roll 2, over rollers 20, 13, 53, 54 to the heated roller 31, and thence to the mandrel 45. The roller 13 is adjustable, and the roller 31 is half-filled with liquid and heated electrically by current supplied by brushes 32 and slip rings, its temperature being controlled by a thermostat. To prevent the paper &c. from absorbing moisture, the whole machine is mounted in an enclosure which is heated by electric heaters 40. Instead of using a heated roller for softening the coating, a solvent may be applied to the paper &c. and its action on the coating delayed, for example by applying it to the uncoated side of the paper &c. and allowing time for it to permeate through to the coating before being wound on the mandrel. The solvent may be monostyrene. The invention may be used for making electric coils as in Specification 545,707, [Group XXXV]. Specifications 506,277, [Group XXXVI], 509,836, [Group VIII], and 532,687, [Group XXXVI], also are referred to.

The rear part of the cycle including the wheel 14 is similarly enclosed, side walls 18, Figs. 3 and 4, being adapted to swing outwards about hinges 19, carrying with them a collapsable rear wall 20. The covering then forms pockets 21 for luggage or passengers, and may also support passenger seats 22. The covering may be spread outwards by telescopic or rack-and-pinion mechanism, either manually or automatically by means of a float 29, which may also control gearing driving a propeller 28 from the motor. An intermediate cover 15 is recessed at 16 for the driver's legs, which are protected by folding side aprons 27 fitted adjacent to footrests 17. The motor cycle is supported when stationary &c. by side props 30 having ground-engaging parts or rollers, each prop being pivoted at 35 and adapted to be depressed by a pedal 34 and raised by a spring 32. The front wheel and casing when used as a rudder are turned through a frictional device or reduction gearing. A small wheel at the front, driven by the main wheel, facilitates climbing up a bank when leaving the water. The motor may be additionally cooled on water by means of a fan or compressed air, or by the passage thereto of water from the river &c. on which the machine is travelling.
