Title: Fuel control system for a gas turbine engine
IPC: F02C9/32
Filed: 1974-11-04
Abstract: 1517514 Gas turbine engine fuel control systems LUCAS INDUSTRIES Ltd 9 Oct 1975 [4 Nov 1974 5 Feb 1975] 47578/74 Heading F1G [Also in Divisions G 1 and G3] The invention relates to a fuel control system for a gas turbine engine comprising a variable delivery pump 11 and a fluid-flow responsive device through which fuel delivered by the pump can flow to the engine. In the embodiment, the fluid-flow responsive device comprises a fluid oscillator 12 having an inlet 13 and two inclined passages 14, 15 also two inter-connected control ports 16, 17 whereby the fluid jet discharging from inlet nozzle 13 is deflected either into passage 14 or 15 when fluid issues either from port 17 or 16. The two passages 14, 15 are connected to an outlet 18 by way of chambers 19, 20 having flow filters 21. The chambers 19, 20 have outlets 22, 23 which contain restrictors 24, 25 which lead to a single restrictor 26 thence to a chamber 27 from which leads a passage 28 connected to an actuator 49 for controlling the pump 11, a fluid reservoir 50 being connected to the passage 28. The outlet 18 leads through a flowmeter 42 to the gas turbine engine 10. For sensing the oscillation of the oscillator 12, a hot-element anemometer 29 in the form of a piece of foil is disposed within chamber 20, signals from the anemometer being passed to circuit 30. A signal from circuit 30 is passed to summing amplifier 35 to which a further signal from a second hot-element anemometer 32 disposed in chamber 27 and passed through control circuit 33 is passed, this latter signal having a frequency which is a function of the filtered flow in the passage 28. The summing amplifier 35 provides a signal which represents rate of fuel flow to the engine. The signal from amplifier 35 is passed to control and comparison circuit 38, also to a read-out device 37. A control circuit 39 is connected to receive engine signals N, engine speed, T 1 , engine intake temperature, P 2  compressor discharge pressure, and #, power demand, circuit 39 passing a signal which represents desired fuel flow to control and comparison circuit 38. A further signal is supplied to the circuit 38 from the flowmeter 42. A feedback signal from the actuator 49 is passed through line 44 to the circuit 38. Output signals from the anemometer 29 vary with the temperature thereof, this temperature being dependent on the rate of fluid-flow past the anemometer.

In apparatus for separating solid particles from fluids, fluid passes through annular operating zone 18, where it is given a rotary motion by helical blades 25, and is then accelerated on passing through converging portion 19, the resulting centrifugal force on entrained particles causing them to precipitate out on wall 19. The particles then fall down and out of tube 20, the fluid entering and passing up internal tube 22. Tube 22 carries an internal plate 23 notched and twisted to form vanes 24 which reduce the rotary motion of the fluid. Fig. 1 (not shown) illustrates a number of these separators working in parallel in a common casing, having upper inlet and outlet and a lower dust hopper. The face 26 of each separator is polygonal, Fig. 4 (not shown), so that they nest together, faces 26 forming a dividing wall across the casing. The fluid may be liquid, but the arrangement is particularly for cleaning polluted air.

Title: Voice transcoder
IPC: G10L21/00
Filed: 1976-11-18
Abstract: A voice transcoder for use in compensating for sound distortions in helium speech, including a plurality of audio frequency channels, each defining a particular frequency band, the center frequencies of the channels being logarithmically spaced and frequency bands together covering the helium speech frequency band to be transcoded. Each channel comprises a band-pass filter coupled to a detector, a divider dividing band-pass filter by detector output to provide a signal having the frequency delivered from the band-pass filter at a standard amplitude, and a mutliplier multiplying divider output by another channel detector output to synthesize a part of the transcoded audio signal, the different parts of the transcoded signal being combined in an adder-subtracter. The said multiplier has one input coupled from divider output in the channel of rank i and the other input coupled from rectifier output in the channel of rank i + x, x being the same for any multiplier. x is selected in accordance with the proportion of helium in the gas breathed by the speaker. Each channel comprises a multiplexer selected according to x for performing the adequate connections to the channel multiplier.

Abstract: 1,243,364. Radio signalling; wired broadcasting. M. FUKATA. 14 Oct., 1968 [16 Oct., 1967], No. 48529/68. Headings H4L and H4R. A system in which a broadcasting station can send a control signal to bring in one or more receivers which are standing by is provided with means to ensure that if the control signal is falsely commenced, e.g. by chance simulation in other signals broadcast from said station, frequency components of said control signal are eliminated for a predetermined time at said station from said other signals. Examples of control signals are, different frequencies lasting for five seconds and a pulse sequence of a single frequency. In one embodiment, broadcast programme signals from a terminal 1, Fig. 1, are taken through two changeover switches 3, 5 to the input of a unidirectional amplifier 6, which feeds a transmitter 7 having an aerial 10. Normally, a direct connection L is provided between contacts 3-2, 5-2 of the switches but, if a false signal is detected by a unit 8 a control circuit 9 operates the switches, and an elimination unit 4 is inserted via their contacts 3-3, 5-3. The false signal may be, for example, four seconds of the above-mentioned two different frequencies and the elimination unit may be a filter rejecting those frequencies. If the control signal is to be sent it is applied from a terminal 2 directly to the input of the transmitter 7, and it is not detected by the unit 8. In a second embodiment (Fig. 2, not shown) the control signal input terminals and the broadcast signal input terminals are paralleled, but when the control signal is sent the detector circuit is broken to prevent operation of control circuit and consequent insertion of the elimination unit. In a third embodiment (Figs. 3A, 3B, 3C, not shown), detection of a false signal is carried out at a monitoring station, which sends a signal by radio or line to the broadcasting station in that case, said signal operating the control unit (9). The control unit may comprise a relay which is in series with a capacitor. Operation is initiated when a false signal is detected, and the relay is held via one of its own contacts whilst the capacitor charges (Fig. 4, not shown). The said relay provides the changeover contacts (3), (5). A detector is described for a sequence consisting of three 0.2 seconds pulses of 1000 c/s. signal, followed by one 1.0 second pulse, with 1.0 second spacings (Figs.5, 6, not shown). The detector may be used either as a false signal detector (first three pulses) or as a control signal detector (all four pulses). The invention may be used either for a radio system or a wired system.
