Inventor: LOWENTHALL HANS
IPC: F23Q2/173
Filed: 1960-08-23
Abstract: 914,134. Gas-fuelled cigarette lighters. COLIBRI LIGHTERS Ltd. July 31, 1961 [Aug. 23, 1960], No. 29127/60. Class 75 (3). Gas from the reservoir of a gas-fuelled cigarette lighter passes to a burner nozzle 18 through a first pre-set pressure reducing valve comprising a resilient polytetrafluoroethlyene block 4 having a bore 5 and compressed by a hollow plug 6 screwed into a brass body 1 and a second adjustable e pressure reducing valve comprising a rubber ball 8 seated on the outlet end of the bore 5 and on the inlet end of a bore 9 in a sleeve 10 adjustably screwed by a knurled flange 12 into the plug 6. Since the block 4 has a higher coefficient of expansion than the body 1 increased temperature causes restriction of the bore 5 to counteract increased gas pressure in the reservoir. The nozzle 18 is formed on the end of the hollow stem 16 of a spring-loaded shut-off valve 14 controlling gas flow from the bore 9 and operated by the igniting mechanism of the lighter. According to the Provisional Specification, the first pressure reducing valve may be fixed to a removable reservoir while the second pressure reducing valve forms part of the lighter structure to which the reservoir is fitted. The second valve may be a screw-operated needle valve and the shut-off valve may be disposed between the two pressure reducing valves.

Title: Improvements in or relating to circuit-arrangements for distributing signal pulses
IPC: H03K5/15
Filed: 1946-10-09
Abstract: 643,272. Thermionic distributers. PHILIPS LAMPS, Ltd. Oct. 9, 1946, No. 30172. Convention date, Oct. 13, 1945. [Class 40 (iii)] In a time-division multiplex communication system time-modulated pulses are applied to a plurality of interconnected thyratrons which fire in turn under the control of successive pulses to pass the intelligence to associated receivers, automatic means being provided to cut off all the thyratrons simultaneously when all have fired. Incoming time or phasemodulated pulses are applied via transformers 20 to the grids of three channel thyratrons 1 ... 3 of which the first has a negative bias 9 less than that 12 of the others. The leading edge of the first pulse fires the first thyratron 1 only, the voltage thereby developed across the cathode resistor 17 transferring the effect of the pulse to the associated receiver 4. At the same time the positive potential developed at the top of the cathode resistor 17 primes the second thyratron 2 which fires upon the arrival of the second pulse, operating its receiver 5 and priming the last thyratron 3. After the third pulse is received all thyratrons will be conducting and a synchronizing pulse is received and applied to a relay 21 which removes the supply voltage from the anodes and thus extinguishes the thyratrons which are then ready to receive further pulses. The relay 21 may be energized instead by the anode current of the last thyratron and the thyratrons may be extinguished by short-circuiting them. If the trailing edges of the signal pulses convey the intelligence these pulses are differentiated before being applied to the thyratrons so that the latter strike in turn when successive trailing edges are received.

Inventor: DAVIDSON JAMES ALEXANDER BREMN
IPC: H03F3/40
Filed: 1953-11-02
Abstract: 780,969. Valve amplifying circuits. MUIRHEAD & CO., Ltd. Oct. 28, 1954 [Nov. 2, 1953], No. 30261/53. Class 40 (6). An amplifier for unidirectional signals comprises an A.C. amplifier preceded and followed by pulsed, synchronized interrupters. In the input circuit, relay contact A3 is normally in series, but is pulsed at regular intervals to shortcircuit the input terminals instead, and at these intervals relay contact A2, which is normally open is closed to short-circuit the output terminals. Contact A3 short-circuits the input before A2 short-circuits the output, while in the reverse direction A2 opens first. The amplifier comprises pentode amplifiers V1, V2 with negative feedback between the anode of the valve V2 and the cathode circuit of the valve V1, and a cathode follower output stage V3. In each of the stages V1, V2, V3 the grid leak is returned to a tap on the corresponding cathode resistor so as to increase the input impedance. As applied to a system for recording the voltages on a number of lines (Fig. 3, not shown) a rotating shaft carries cams which sequentially close one contact operating the interrupter and a second contact which operates a line selector switch.
