Title: Improvements in apparatus for the detection and measurement of knock in internal combustion engines
IPC: G01L23/22
Filed: 1945-04-24
Abstract: 601,234. Indicating detonations. ANGLOSAXON PETROLEUM CO., Ltd., PIGNEGUY, P. G., and CLEMENT, D. M. April 24, 1945, No. 10322. [Class 7 (ii)] A pick-up unit is exposed to cylinder combustion pressure and connected to an electric circuit which includes two thermionicallyoperated indicators, operating respectively in response to normal interruptions produced by the pick-up and to interruptions corresponding to abnormal knock, which exceed a predetermined duration. The pick-up unit comprises a steel plate, one side of which is exposed to combustion pressure, and against the other side of which a ball is pressed by an adjustable spring; when knock occurs, the ball breaks contact with the plate and opens a minute electric circuit. The unit is placed at X in the circuit shown, the normal interruptions being indicated by clicking in headphones marked 2000 #. Direct current is obtained as with radio apparatus. A two-load potentiometer EF provides tapping points for negative bias on a thermionic valve V1 and a gas discharge tube GT1C. The negative bias supplied to the valve through the pick-up unit reduces to zero the anode current through the valve V1 and hence through the headphones. The grid of the second valve V2 is normally at a small positive potential and thus the valve passes a small steady current. Due to the resistance R1, a small voltage across the valve V2 in series with the winding of a relay and condenser C is insufficient to trigger the gas discharge tube GT1C. When the negative bias on the grid of valve V is removed owing to detonation, the voltage across the valve V2 rises and causes a flow of current into the condenser C. When the voltage across the gas discharge tube reaches a critical value selected to indicate the heavy knock, sudden discharge from the condenser C operates the relay which flashes a light bulb.

Title: Fuel control systems for gas turbine engines
Inventor: MOYES SIDNEY JAMES EDGAR
IPC: H02P23/00
Filed: 1958-04-02
Abstract: 896,293. Automatic control-systems for gasturbines. POWER JETS (RESEARCH & DEVELOPMENT) Ltd. April 2, 1959 [April 2, 1958], No. 10693/58. Class 38 (4). In an automatic control-system for a gasturbine an operating condition of the turbine is maintained constant by varying the fuel supply by a servo-mechanism controlled by an electromagnetic actuator energized through a variable resistance by a voltage proportional to the operating condition. As shown, the position of a piston 15 controlling the delivery from a fuel pump 11 by varying the angle of a swash-plate 11c is adjusted by a servo-mechanism 16, whereby movement of a spindle 22 adjusts the pressure difference across the piston 15 by connecting pressure pipes 25, 26 to a fuel delivery pipe 24 or to return pipes 27, 28 to a fuel tank 9. In the null-position shown, the spindle 22 blocks the flow to or from pipes 25, 26 and the piston 15 is maintained stationary and the fuel flow held constant. The valve spindle 22 is movable endwise against a spring 23 by actuators 30, 40, 50 acting through linkages 31, 41, 51 on an abutment 22a. The actuator 30 is energized through a variable resistance 33 from a tacho-generator 32 driven from the gasturbine, the resistance 33 being adjusted so that at a required speed the current through the actuator is such as to cause the spindle to takeup the null-position. The actuator 40 is energized by a jet-pipe thermocouple 42 through an amplifier 43 and a resistance 44 so as to tend to maintain the jet-pipe temperature constant. An actuator 50 is energized through a variable resistance 52 by a function generator 55 deriving the ratio of engine temperature to inlet temperature, from thermocouples 42, 56. A slider 53 of the variable resistance 52 is positioned by a relay coil 60 in dependence on the measured value of the ratio of the turbine speed to the square root of the inlet temperature, derived by a system as disclosed in Specification 759,261. The engine is normally controlled by manual adjustment of the speed resistance 33, the resistance 44 being set to limit the engine temperature and the resistance 52 being set to avoid compressor surging during acceleration. Alternatively, the slider 53 may be positioned in dependence on a measure of the non-dimensional mass flow of air through the turbine.

Abstract: 920,253. Gas turbine Jet propulsion plant. ROLLS-ROYCE Ltd. March 18, 1960 [March 26, 1959], No. 10734/59. Class 110 (3). A by-pass engine has a further rotary compressor arranged at the turbine end of the engine to compress air flowing from the by-pass duct to the exhaust assembly. A by-pass engine is stated to be a gas turbine jet propulsion engine comprising at least one compressor, a heater wherein part of the air compressed in the compressor is heated, a turbine operated by the heated air for driving the compressor, an exhaust assembly including a propulsion nozzle and a by-pass duct which conveys part of the air compressed in the compressor to the exhaust assembly without the air passing through the heater and turbine. The air in the by-pass duct may pass to atmosphere either through a separate nozzle or through the same nozzle as the turbine exhaust gas. The engine comprises a low pressure compressor 10, 19, a high pressure compressor 12, combustion chambers 13, a high pressure turbine 14 and a low pressure turbine 15 connected in flow series between an air intake 16 and an exhaust assembly 17. A by-pass duct 18 receives part of the air compressed in the first half 10 of the low pressure compressor and delivers it direct to the second half 19 of the low pressure compressor. The high pressure compressor 12 is driven by the high pressure turbine 14 through the shaft 23. The first half of the low pressure compressor 10 is driven by the low pressure turbine 15 through a shaft 20 and the second half of this compressor consists of blading 19a forming extensions of the blades 15b. The shaft 20 is mounted in bearings 21, 22 adjacent the bearings 25, 24 of the high pressure shaft 23 so that the rotors of the compressors 10, 19 and turbine 15 are overhung. The shaft 23 is kept as short as possible by suitable design of the combustion chambers which may have double-backed flame tubes. The high pressure compressor 12 may be designed to be as small as possible and the by-pass ratio selected to be high. In this case guide vanes are provided at the inlet to the first stage rotor blades. The exhaust assembly 17 comprises a series of angularlyspaced shoots 17c of increasing radial dimension for delivering the by-pass air into the turbine exhaust gases.
