A traffic control system comprises a master controller 10 feeds information 11 to local controllers 12, 13, 14 controlling the signals 18, 19, 20 respectively additional information being fed to the local controllers from detectors 25, 27 situated at the cross-roads so that the signals from master controller 10 can be modified or modulator 42 and is transmitted to master unit 10 via transmitter 44. Oscillator 55 for detector 32 has a different identification frequency (600 c/s). Circuit details of the multivibrator, identification overridden. Information from the detector is also transmitted to unit 10. The invention resides in the transmission link connecting the master and local control units and the detector. The link as described is a radio link or it may be a twowirelink each of the detector units having a distinct frequency so that the origin of the signal transmitted from them can be determined. Detector 28 and detector unit 29. A vehicle passing over 28 energizes a one-shot multivibrator 37 connected to a generator 39 developing a fixed number of output pulses which then energize oscillator 41 by a fixed frequency (400 c/s), The oscillator output modulates the frequency shifted carrier received from master unit 10 (via channel 200, Fig. 1) in a single side band carrier suppressed oscillator and detector unit are given (Fig. 3, not shown).

Title: Surfacing torch with external power feed
IPC: B05B7/20
Filed: 1960-11-01
Abstract: 958,510. Spraying fusible materials. COAST METALS Inc. Nov. 1, 1960 [Dec. 2, 1959], No. 37578/60. Heading B2F. A flame spray torch has a tip 16 with gas jet orifices 120 arranged in a U-shaped pattern so that the flame is open at the top, and powder is dropped from a nozzle 21 into that flame opening and sprayed on to the work. The nozzle 21, which is supplied from a holder 20 via a flexible tube 72, is located ahead of the tip face so that the falling powder stream avoids eddy currents at the face. A valve system controlling powder flow includes a rod 74 sliding in a sleeve 76, and normally urged against the flexible tube 72 by a spring 82 acting on a collar 80 of the rod to squeeze the tube closed. The sleeve 76 is also urged against the tube by a spring 100. To provide powder flow the rod and sleeve are urged rearwardly by a pivoted trigger 86 which firstly acts upon a bar 90 on the sleeve to withdraw the sleeve from contact with the tube, and the sleeve, in turn, contacts the collar 80 to withdraw the rod. The rear end of the latter extends into an opening 78 and may be held in a desired position by a set screw 116. The sleeve 76 slides through an outer sleeve 106 and may be held in a desired position by a set screw 110. The latter can thus hold both the sleeve and rod in positions which only partially open the powder tube. Fuel gas and oxygen are fed through tubes 54 and 55 and valves 64, 65 respectively to the gun tip. Powder flow from the holder 20 is assisted by an electrical vibrator 32 operated by a press-button switch 44, and by the provision of a smooth surfaced metal plate 30 fitted against the inner surface of the holder.

Title: Improvements in or relating to vacuum tubes particularly for use in radio sets
IPC: H04B15/00
Filed: 1929-12-07
Abstract: 340,396. Valve circuits. ARCTURUS RADIO TUBE CO., 260, Sherman Avenue, Newark, New Jersey, U.S.A.-(Assignees of Krahl, W. L. ; 73, Orange Road, Montclair, New Jersey, U.S.A.) Dec. 7. 1929, No. 37580. Convention date, Dec. 7, 1928. [Class 40 (v).] The hum arising from the use of alternating or fluctuating current for indirectly heating the cathode of a detector or other valve employing a grid leak in its input circuit, is eliminated by an arrangement which prevents the supply current from flowing through the grid leak. As shown in Fig. 2, the supply current for the heater 16 comprises a transformer 29 and a series resistance 25. The cathode 14 is connected to the junction point 15 of the heater 16 and the resistance 25, which form two adjacent arms of a bridge. The other two arms are formed by the inherent capacity 24 between the grid and the heater terminal 17, and by a small variable condenser 33 connected between the grid and the terminal 27 of the resistance 25. The supply secondary 28 forms one diagonal of the bridge, and the grid leak 20 and its associated condenser 21 form the other diagonal, so that by suitable adjustment of the condenser 33, no supply current will traverse the grid leak and no hum voltage will appear on the grid. The grid condenser 21 may be connected to the terminal 27 and used as the balancing-capacity ; and the balance may be attained by variation of the resistance 25. In a modification shown in Fig. 4, the cathode 38 is connected to a slider 58 on a supply potentiometer 57, and adjustment of the slider enables a balance to be obtained in the bridge comprised by the two sections of the resistance 57 and the inherent capacities 59, 60 between the grid 36 and the opposite terminals 41, 42 of the heater 40.

Abstract: 1473106 Amplifying circuit EMI Ltd 5 Aug 1974 [11 Aug 1973] 38152/73 Heading H3W A television camera arrangement includes a pick up tube coupled to a head amplifier 1 by reactive components which form a filter for the output signals from the tube, the reactive components having a resonant frequency embraced within the pass band of the filter, the pass band being defined by the frequencies where the amplitude response is 3 db down. In practice Cc and Ca are stray capacitances at the output and input of the tube and amplifier respectively with L the added component. A feedback path 2 may be provided around the amplifier 1 with signals coupled into the input path to the amplifier in a sense which tends to reduce the effective inductance as seen by the signals thereby causing a filter characteristic imposed by the effective inductance and the capacitances to embrace within its pass band the resonant frequency of the unmodified inductor and capacitances. The coupling means can be a ferrite cored transformer T, and may be a current transformer (not shown) with its primary winding in a second feedback path around a second amplifier 2 in the first feedback path. The first feedback path may have an amplifier 2 and inductor C 1  connected in parallel. The inductor 1 and transformer secondary may be combined as one component.

Abstract: 919,796. Automatic vibration amplitude control. IMPERIAL CHEMICAL INDUSTRIES Ltd. Oct. 25, 1961 [Nov. 9, 1960], No. 38488/60. Class 38 (4). In an arrangement for automatically maintaining constant the amplitude of vibration of an A.C. operated vibrator, an A.C. signal dependent on the amplitude is rectified and compared with an adjustable D.C. reference signal, any difference serving to control, through an amplifier, trigger circuit, blocking oscillator and phase-controlled rectifier, the magnitude of a correcting direct current injected into the vibrator energization circuit. In the arrangement described the vibrator moves an armature relative to a pair of fixed coils 3, 4, one, 3, being energized by D.C. and the other, 4, producing an A.C. signal dependent in amplitude on the amplitude of vibration. The A.C. signal is rectified at 7 and opposed to an adjustable stabilized reference direct voltage, representing the desired amplitude, obtained from a Zener diode 13 associated with a potentiometer 12. Any difference, representing amplitude error, is amplified by a D.C. transistor amplifier 14, 15, having stabilizing feed-back circuits 40, 47, and applied to a Schmitt type trigger circuit, including transistors 20, 21, which is operated at mains frequency by A.C. applied from a mains transformer secondary 24 through a transistor 22. The phase of the mains frequency output from the trigger circuit is thus dependent on the amplitude error and is applied through a condenser 63 to control a blocking oscillator including a transistor 26 and a transformer 28. The outputs from the secondary windings of transformer 28, which are at mains frequency and have a phase corresponding to the amplitude error, are applied to control parallel-connected silicon or thyratron rectifiers 29, 30 supplied from a mains transformer 25 so that a direct voltage is produced across a resistor 58 and thereby injected in series with the A.C. supply to the vibrator energization coil 31 to correct the error.

In an abbreviated addressing arrangement for digital computers, a transfer (i.e. " jump ") instruction contains a part only of the address to which transfer is required, this part being combined with further address digits to form the effective address to which transfer is required. A programme address register 40 is normally incremented by unity at 41 but when a transfer instruction is in the instruction register 20, the operation code part of the instruction causes the 5-bit address part to replace the lowest five bits in the address register 40 to provide the transfer address. If the transfer address differs from the current one by a greater number of bits, an auxiliary register 44 filled by a previous instruction can provide five higher order bits for the address register 40, these bits being supplied via a gate 46. The computer memory 10, 80 may be a magnetic core matrix.
