Title: Improvements in or relating to gas-turbine fuel-systems
IPC: F02C6/00
Filed: 1946-09-30
Abstract: 618,760. Gas turbine plant ; jet propulsion plant. MORDELL, D. L., and CORBITT, R. W. Sept. 30, 1946, Nos. 22777/47 (divided out of 618,479), and 23027/47. [Class 110 (iii)] In a gas turbine plant having one or more reheat stages into which fuel is injected the atomization of the fuel in the injector is assisted by air or combustion gas taken from a point in the engine which is at a higher pressure than that in the reheat stage. The plant shown, Fig. 1, comprises an axial flow compressor 12 supplying air to the main combustion chambers 13 which supplies combustion gases to a turbine 15 driving the compressor, reheat chambers 16 in which fuel is injected by nozzles 20 and a further turbine 17 mounted on the same shaft 10, from which power may be taken, as the turbine 15. The nozzles 20 are supplied with fuel through a pipe 19 and air through a pipe connected to the outlet of the compressor 12. The nozzles 20, Fig. 2, comprise a fuel supply duct 21 leading into a swirl chamber 22 through a series of helical grooves 23 in a swirl nozzle 24. To obtain good atomization at low fuel flows, air is injected in the swirl chamber 22 from the supply pipe through a series of tangential plots 27 in a plate 28 encircling the chamber 22. The supply of air passing through the pipe may be controlled by an automatic valve under the control of the fuel pressure so that the air supply is cut-off at high fuel flows. Alternatively, the air supply may be operative over the whole range of fuel flows in which case the air supply is cut-off when the fuel supply to the injection- 20 is cut-off. Instead of air, combustion gases tapped off from the combustion chamber 13 may be used, in which case, the fuel is preheated before leaving the injector. The invention may be applied to a jet propulsion engine to reheat the gases before they enter the propulsion nozzle. The fuel injector 20 may then be mounted on the apex of the exhaust bullet and supplied with air from the compressor diffuser or combustion gases from the combustion chamber. The fuel injector may be enclosed in a flame tube. According to the second Provisional Specification the invention may be applied to a gas turbine power plant in which there is a high pressure turbine driving a high pressure compressor and supplying useful output and a low pressure turbine driving a low pressure compressor. The gases are reheated between the turbines and, if desired, the compressed air from the high pressure compressor may be pre-heated before passing into the main combustion chamber in a heat-exchanger heated by the exhaust gases of the high pressure turbine before they pass into the re-heat chamber. In another arrangement described in the Specification referred to the invention is applied to a multistage turbine in which the re-heat chambers are formed by the spaces between the fixed guide blades which spaces are enlarged if necessary.

Title: Meter interrogation systems
IPC: H02J13/00
Filed: 1973-05-15
Abstract: 1409489 Interrogation of remote stations GENERAL PUBLIC UTILITIES CORP 15 May 1973 23069/73 Heading G4H Apparatus for reading meters 28 from a central station 20 incorporates means for determining and allowing for the maximum delay path in a communication link 32 connecting the station to the meters. As described, 16-bit FSK meter identifying signals are sent via a power distribution network to transponders 30, and corresponding meter reading signals are sent back to the station. Each reading operation consists of three stages: (1) meter identity codes are sent from a computer 40 to a store 50, (2) each code is transmitted to the transponders and the corresponding reading from the actuated transponder is received and stored in 50, and (3) the readings are transferred from store 50 to computer 40. The station is shown in more detail in Fig. 6. Identity codes are fed from store 50 via a register 94 to a modem 90 comprising a FSK modulator 95 a filter 97 and a squaring circuit 98. Each incoming meter reading passes through 97, 98, a converter 64 and a register 96 to store 50; the square wave pulses representing each (FSK) bit also pass through a differeniator 81 to increment a counter 83 which counts from the start of the bit arriving via the shortest path to the end of the bit arriving via the longest path, a monostable 82 effecting transfer of half the count in 83 (which is then reset) to a register 85. When and only when the count corresponding to the next bit reaches the value in 85, a comparator 86 sends a signal 86A to strobe the corresponding bit in register 96: thus the meter reading signal in 96 is sampled at a notional mid-point of each bit as determined by the length of the previous bit, so that the effects of the maximum delay path (possibly variable) are taken into account. The output from 98 also causes an averaging circuit 101 to supply to an oscillator 88 a voltage depending on the number of pulses received: the frequency of 88 is inversely proportional to the voltage so that when an increased number of pulses is received by 101 (owing to an increase in the maximum delay path) the frequency of 88 drops. The output from 88 is used to strobe register 94 so as to control the rate of transmission of the identity codes to modem 90. Each transponder 30 contains equipment similar to that of Fig. 6 (Fig. 7, not shown), here the identity signal is fed to a register 130 and compared at 140 with the meter identification code in a store 142 (which code may be set manually). Specification 1,409,490 is divided from the present Specification and has identical description but different claims.

Title: Thermionic voltmeter for alternating voltages
Inventor: WIGAN EDMUND RAMSAY
IPC: G01R17/16
Filed: 1954-08-12
Abstract: 783,967. Voltage measuring bridges. MUIRHEAD & CO., Ltd. Aug. 12, 1954, No. 23367/54. Class 37. A thermionic A.C. voltmeter comprises an input voltage divider, an amplifier, an attenuator, and a further amplifier in cascade energizing a four-element four-terminal resistive bridge network having at least one non-linear resistance element; the output of the second amplifier being applied to diagonally opposite bridge terminals together with an adjustable direct voltage and a direct voltage indicating instrument being connected to the remaining bridge terminals to show null when the second amplifier output is at a predetermined value, so that the input alternating voltage value is determined from the voltage divider and attenuator calibration when adjusted for null indication. Fig. 3 shows a circuit wherein an alternating input voltage is applied to a calibrated tapped potential divider 32 whose output is amplified at 33 and fed to an adjustable decade attenuator 34 whose output energizes a further amplifier 35, whose cathode follower output is directly coupled through capacitances 39, 40 in series to the input diagonal of a bridge 38 having four resistance elements of which element 13 is non,- linear comprising lamps and elements 10, 11, 12 are linear, which is adjusted for balance of meter 19 for a known A.C. input. An auxiliary D.C. (less than the working A.C.) is derived from the cathode of the amplifier output and is regulated by variable resistance 41 across capacitance 39 to a value measured by meter 42 across capacitance 40, which should be less than of the working alternating component. The input signal is thus measurable by adjusting the attenuator until the bridge is balanced at a known A.C. input. Calibration may be carried out by supplying a known input signal to the bridge from a D.C. source standardized by comparison with a standard cell and adjusting the variable resistance arm for bridge balance. Multiple lamps in series, parallel, or seriesparallel may be used for the non-linear resistance arm which may alternatively comprise thermistors. The bridge may comprise two non-linear elements of the same temperature coefficient in opposite arms, and ambient temperature changes may be compensated by connecting in the non-linear resistance arm a further non- linear element of negative temperature coefficient and insensitive to the current in that arm (e.g. a carbon filament lamp), or injecting in series with the meter in appropriate sense the output of a thermocouple exposed to ambient temperature, or inserting positive temperature coefficient resistances in series with the fixed bridge arms. The auxiliary direct current may be supplied to the bridge from a variable potentiometer in series or in parallel with the A.C. input (Figs. 1, 2, not shown).
