Title: Fuel control systems for tas turbine engines
IPC: F02C9/38
Filed: 1974-08-21
Abstract: 1472747 Gas turbine engine fuel systems LUCAS INDUSTRIES Ltd 21 Aug 1974 [6 Sept 1973 26 Sept 1973] 41883/73 and 45058/73 Heading F1G [Also in Division G3] A fuel system for a gas turbine engine comprises a spill valve varying the pressure of fuel flowing to the engine under the control of a pilot valve responsive to electrical signals representative of engine operating conditions, there being means for isolating the pilot valve from the spill valve so that control of the latter can be assumed by a further valve. The spill valve is formed by a ball-type valve 17 connected across a second stage, engine driven, liquid fuel gear-pump 16. Valve 17 is positioned by the servopressure in line 19 controlled by a flapper type pilot valve 21 actuated by a torque motor 22 in response to signals from an electronic unit 23 representative of the speeds N G , N F  of the gas generator and power turbines 10a, 10b respectively and to the position of the gas generator speed setting lever 24. Unit 23 is cooled by fuel flowing through heat exchanger 40. In the normal running position, shown, of a manually operable shut-off cock 25, line 19 connects with pilot valve 21 via cock inlet and outlet 26, 28, whereas the outlet of pump 16 connects with burner manifolds 11, 12 via cock inlet and outlet 27, 29 respectively and a pressurizing valve 30. The latter has a closure member 31 which is urged open by fuel pressure against spring 33. An adjustable restrictor 34 in parallel with valve 30 provides a flow to the engine even when the valve is shut. Burner manifolds 11, 12 are connected in parallel to the common outlet of valve 30 and restrictor 34, fuel not flowing to manifold 12 until the engine has started and the fuel pressure increased sufficiently to unseat valve 35. Servoline 19 includes a relief valve 37 communicating with the inlet of pump 16, the spring loading of valve 37 being variable by means of a stem 38 engaging cam surface 39 on shut-off cock 25. To obtain manual control of the servopressure in line 19 in an emergency, cock 25 is moved anti-clockwise to shut outlet 28 and thus isolate valve 21 from line 19, the servopressure then depending upon the loading of valve 37. The electrical circuitry deriving the control signals for torque motor 22 during starting and normal running is described, Fig. 2 (not shown).

Title: Digital signal transmission systems and to alphabet code converters for such systems
IPC: H04B17/40
Filed: 1977-10-11
Abstract: An alphabet code converter (ACW1) arranged at the transmitting end of the digital transmission system generates output signals in accordance with the code alphabets provided, which signals only have a certain maximum number of equal-valued elements, for example zero bits. For the purpose of no-address fault location, control signals are provided which cannot occur during normal operation and which have a relatively large number of identical code elements following one another directly. For this reason, an alphabet code converter (ACW1) is proposed which can be switched (S1) during the fault locating operation and which generates a ternary loop closure signal from a binary loop closure signal. The system can be used for digital transmission links, particularly for PCM signals, having a relatively large number of regenerative repeater stations. <IMAGE>

Title: Semiconductor devices
IPC: H01L29/747
Filed: 1965-10-05
Abstract: 1,066,159. Semi-conductor devices. MATSUSHITA ELECTRIC INDUSTRIAL CO. Ltd. Oct. 5, 1965 [Oct. 17, 1964; June 29, 1965], No. 42280/65. Heading H1K. A semi-conductor A.C. switching device comprises a substrate P2 of one conductivity type with two first regions N1, N2 of the opposite type each containing regions P1, P3 of the first type. Electrodes S and D ohmically contact regions N1 P1 and N2 P3 respectively and regions N1 and N2 are connected by a channel produced in region P2 by biasing control electrode G on insulating layer In which overlies P2. Biasing between electrodes S and D provides that junctions N1, P2 and N2 P3 are forward biased while N1, P1 and P2 N2 are reverse biased; thus electrons injected from N1 are stored in the vicinity of P2 N2 depressing the barrier until the " ON " state is reached. The switching or breakdown voltage is high if no control voltage is applied to G, but falls as the control voltage causes formation of the conducting channel. The device may be formed of silicon doped with boron and phosphorus with aluminium electrodes and insulator region of silicon oxide.

Filed: 1975-10-17
Abstract: 1512100 Television SONY CORP 17 Oct 1975 [21 Oct 1974] 42805/75 Heading H4F Apparatus for reproducing a colour video signal from a composite signal recorded on video tape T and which includes a chrominance component containing a burst signal occurring only during spaced intervals, comprises transducers 4 for reproducing the signal recorded on the tape, a variable gain amplifier 20 receiving said chrominance component and having an output at which a level-controlled chrominance component is provided, a gate 26 receiving said level-controlled chrominance component and being controlled in synchronism with said spaced intervals so as to provide a first output signal during each of said intervals, a crystal filter 32 receiving said first output signal and being tuned to a predetermined frequency for passing only said burst signal as a second output signal, and means for controlling the gain of amplifier 20 in accordance with the combined levels of said output signals. The output of filter 32 is applied to a level detector 34, and the output signal from gate 26 is also applied to a buffer amplifier 31, the signals from detector 34 and amplifier 31 being added by a circuit 33 and passed to a level detector 35 which provides a D.C. signal applied through an amplifier 36 to control the gain of amplifier 20. A highpass filter 13 and a lowpass filter 19 respectively separate the frequency-modulated luminance signal and the chrominance component, which, as recorded on tape T, is frequency-converted to a frequency band lower than a standard band therefor, from the reproduced composite signal. The chrominance component is frequency-reconverted at 21 after passing through amplifier 20, the resultant chrominance component being added at 17 to the demodulated luminance signal. However, if the output from detector 35 falls below a predetermined level, a colour killer 37 acts on a switch 23 to disconnect the reconverted chrominance component from adder 17, the highpass filter at the same time being by-passed by means of switch 14 to apply the reproduced composite signal directly to demodulator 16. Modifications in the arrangement of level detectors 34, 35 are described in the Specificaion.
