Patent GB-601129-A (GB)
Title: Improvements in or relating to electric multi-channel pulse communication systems
IPC: H04J3/00
Filed: 1945-06-01
Abstract: 601,129. Multiplex pulse signalling. STANDARD TELEPHONES & CABLES, Ltd. June 1, 1945, No. 13868. Convention date, July 29, 1944. [Class 40 (v)] In a multi-channel pulse communication system the pulses of each channel train have different characteristic durations, which are generated by applying a train of base pulses to shock-excite a resonant circuit to produce a single undulation for each pulse, the resonant circuits for the respective channels being tuned to different frequencies. In the three-channel system described, a master pulse-generator produces a train of rectangular pulses to operate channel 1, Fig. 3 (a), and after suitable phase displacements channels 2 and 3. In each channel, these pulses are applied to a pulseshaper 2, Fig. 2, comprising a tuned circuit 14 shunted by a diode 15. The positive-going leading edge of each pulse shock-excites circuit 14 to produce positive undulation 21, for example, the width of which depends on the frequency to which circuit 14 is tuned. Subsequent negative undulations such as 20 are damped out by diode 15. The resultant undulations 21 are passed through amplitude limiter and shaper 18 which produces rectangular pulses which are mixed with those of the other channels for transmission. Width modulation of the transmitter pulses is produced by a "reactance" valve 16 shunted across the tuned circuit 14, the reactance of which is varied by the signals from source 11. At the receiver each channel circuit comprises a pulse width discriminator and demodulator, Fig. 5. The complete pulse train is applied to a limiter 37 in the anode circuit of which is a tuned circuit 40, the natural period of which is twice the duration of the maximum width of the desired pulses. Connected across circuit 40 is a valve 41 which is blocked by the pulses applied to its grid 47, but at other times damps undulations in circuit 40 which would drive point 43 positive. The clipping and amplifying stage 49 is biassed to respond only to positive impulses of above a predetermined level. Pulses of the desired channel produce the maximum output from circuit 40 and can be discriminated therefore by stage 49. The leading edge of a pulse 39 produces a negative undulation 52, Fig. 6 (a), in circuit 40, the valve 41 being blocked. The succeeding positive undulation 53 is reinforced by the trailing edge of pulse 39 and the portion 53a above the clipping level 57 is passed on by stage 49. The succeeding negative undulation 55 is damped out by valve 41 which is now unblocked. Each pulse therefore produces an output undulation 53a, 54a, 56a, &c., the amplitude of which depends on the input pulse widths. The envelope of the output undulations, which represents 'the' modulating signal, is recovered by passing them through a low-pass filter. Specifications 601,128 and 601,135 are referred to.

Abstract: 964,926. Agitator drives. WIBAU-WESTDEUTSCHE INDUSTRIE UND STRASSENBAUMASCHINEN G.m.b.H. April 11, 1962 [April 14, 1961], No. 13948/62. Heading B1C. [Also in Division F2] A device for automatically starting and stopping a drive in accordance with the load comprises floating gearing in a casing 11, interposed between driving means 1-10 and an output shaft 12, and an arm 15 secured to the casing 11 and being in operative engagement with a control member 19 for starting and stopping the drive, the arm causing movement of the control member 19 in response to variation of the reactive torque on the casing. As shown, the output shaft 12 carries stirrer elements 14 in a mastic asphalt cooker 13 and the driving means comprises an internal combustion engine 1, a flexible coupling 5, a magnetic clutch 7 and Vee-belt gearing 8, 10. The rod 19 carries, at its upper end, a pin 16 engaging a slot in the arm 15 and carries, at its lower end, a limit switch 23 which is included in a circuit 24 connecting a battery 4 with the magnetic clutch 7. A compression spring 20 surrounds the rod 19 and the spring bias may be adjusted by a nut 21. In operation, when the maximum permissible load is reached, limit switch 23 is opened thereby causing the clutch 7 to release and the drive to be interrupted. When the load becomes less, the reactive torque on the casing 11 diminishes and the spring 20 moves the rod 19 upwardly, thereby closing switch 23 to re-engage clutch 7 and hence restore the drive. The fluctuations of load are indicated by an instrument 25 and recorded by the pen of a recorder 26. The response of the control element may be transmitted to the means for starting or stopping the drive by mechanical, electrical, pneumatic or hydraulic means or by a combination thereof.

Abstract: 457,101. Valve generating circuits. RADIOAKT.-GES. D. S. LOEWE, 10, Wiesenweg, Steglitz, Berlin. May 20, 1935, No. 14657. Convention date, May 31, 1934. Addition to 423,427. [Class 40 (v)] Saw-tooth generators for producing deflecting voltages in phase opposition for television purposes, as described in the parent Specification, comprise a two-stage amplifier in a single bulb. The frame-frequency generator comprises a condenser 5 charged through a high resistance 7 and discharged through a gas-filled triode 1. The voltage developed across the condenser 5 is only a small fraction of the supply voltage. The resulting saw-tooth voltage is applied to one grid of a double triode valve 3, the corresponding anode 3a supplying a shielded line leading to one deflecting-plate of the cathode-ray tube. This anode is also coupled through a potential-divider 15, 16 to the other grid of the valve 3, the anode 3b of which supplies phase-reversed voltages to the second deflecting-plate through a shielded line. These two lines may be arranged in close proximity, e.g. as twisted flex. The line-frequency generator 2, 4, 6 may be arranged similarly to the frame-frequency generator 1, 3, 5, except that the discharge of the condenser 6 is retarded by a resistance or choke coil 19, and a resistance 20 is inserted in the lead to the grid of the amplifier 4. The condensers 5, 6 are shunted by safety glow lamps 21, 22 which break down before damage is done to the condensers if the gas-filled triodes are not in action. The lamps 21, 22 produce temporary relaxation oscillations which deflect the cathode-ray and prevent it from damaging the screen during the starting- up process. Their quenching-voltage is higher than the ignition voltage of the gas-filled triodes 1, 2. The lamps 21, 22 may operate directly on the deflecting-plates instead of acting through the amplifier 3. The circuit elements in the area 30 are spaced apart from those in the area 29 to prevent back coupling ; and similar precautions may be taken in the frame-frequency generator. Resistances 23, 25 for regulating the picture size, and resistances 24, 26 controlling the frequencies are brought out of the casing for manual control. Specification 426,055 is referred to.
