Title: Improvements in and relating to fuel injection system for multi-cylinder combustion engines
IPC: F02M63/00
Filed: 1946-04-20
Abstract: 611,423. Supplying liquid fuel. WIENE, P.E. April 20, 1946, No. 12126. Convention date, April 21, 1945. [Classes 7 (v) and 7 (vi)] In a fuel injection system for multi-cylinder engines having two or more fuel injection valves fed by a single pump from a common pressure pipe or space communicating with the injection valves through control members or distributors driven by cams, or eccentrics, the delivery of fuel to the injection valves is prevented if the control members seize. In Fig 1, a distributor cock 1, oscillated by a lever 2 urged by a spring 5 against a cam 4, connects the fuel delivery pipe 7 of a pump 23 to passages A, B, leading to injection valves, on the parts a, b, of the cam and to a release port C on the highest part c of the cam so that the cock 1 can only remain seized in the last position. In a modification, Fig. 2, the cock is replaced by slide valves 1 positioned in each branch pipe 10 connecting the pipe 7 to an injector valve, each valve 1 being closed positively by a cam 4 and urged upwards by a spring 5 for opening so that it can only stick in the closed position with annular chamber 6 out of register with the pipe 7 and 10, the fuel from the pump then escaping through a safety valve 12. The pipe 7 is forked to deliver fuel to the valve at diametrically opposite points balancing the lateral thrusts, and a bore may be provided in the valve 1 registering with a passage connected to the pipe 10 when the valve is closed to drain off any fuel leaking into the pipe 10 when the valve sticks. The annular chamber 6 may be replaced by a cavity with a slant control edge, rotation of the valve 1 varying the commencement of injection. In Fig. 17 of which Fig. 18 is a development, cavities 45, 45<1> connected by ducts 46, 46<1> to an annular chamber 47 in the valve 1 control the delivery of fuel entering the ports 44, 44<1> to a pipe 48 leading to an injection valve. The position of the control edges 49, 49<1>, controlling the beginning of the injection period is adjusted by means of a screwed sleeve 54, and the end of injection, controlled by the slant edges 50, 50<1> is adjusted by rotation of the valve 1. The inlets 44, 44<1> are blocked at the top of the up-stroke of the valve, so that no fuel is injected if the valve sticks, and the strokes of the fuel pump are arranged so that no fuel is being delivered when the pipe 48 is connected to the inlets 44, 441 on the downstroke of the valve 1. The slide valves may be reciprocated by eccentrics which are not rigidly connected thereto, and two pumps may deliver fuel through non-return valves to the common pipe feeding the branches to the injectors. In engines starting by compressed air the starting valve holds the control members in the position in which they shut-off fuel delivery.

Title: Improvements in or relating to fire extinguishing systems
Inventor: PUCILL PETER MELBURN
IPC: A62C99/00
Filed: 1966-03-18
Abstract: In a fire extinguishing system of the kind in which, in response to a predetermined rise in temperature, carbon dioxide is directed through a plurality of nozzles into a zone or zones of fire risk, a single large container of liquid carbon dioxide under pressure is connected via intermediary means, operable by the heat detector means to a pressure operated device which opens the valves to the nozzles.  The pressure operated device may be a piston and cylinder device.  The intermediary means may embody a timing unit which allows a single charge of CO2 or a plurality of charges at spaced intervals to pass, optionally after a delay following the detection of the predetermined temperature rise.

Abstract: 1302807 Measuring parameters of a gas turbine, electrically GENERAL MOTORS CORP 29 April 1971 [3 Aug 1970] 12159/71 Heading G1N [Also in Division G4] The turbine inlet temperature of a gas turbine engine is measured by generating analogue potentials corresponding to the variables listed below and solving the following equation: where: T t  = Turbine inlet temperature T b  = Burner inlet temperature P c  = Compressor discharge pressure F = Mass fuel flow C = Engine constant (given) K = Engine air-flow factor. The factor K is dependent on engine speed and may be expressed as a function of the turbine expansion ratio which is the ratio of compressor discharge pressure P c  to turbine exit pressure P t , see Fig.5. The two pressures are measured by known transducers 10, 11 and analogue signals corresponding to the pressures amplified respectively by amplifiers 16, 14. The P c  signal is inverted and fed together with the P t  signal to the divider-multiplier circuit 20 which is also fed at terminal 23 with a signal representing the constant C. The circuit 20 forms the factor P c /P t  x C and may be a time-division divider-multiplier of the kind described in Specification 1302806.  The output of circuit 20 is fed to a function generator 26 which forms the factor 1/K by synthesizing the reciprocal of the curve shown in Fig.5 from the transfer functions of three operational amplifiers 125, 135, 145, Fig.7. The amplifiers 125, 135 have input and feedback impedances dimensioned to provide the transferfunction curves shown and, in addition, amplifier 135 is provided with diode 144 to prevent the output from going negative. The input is applied to both amplifiers and the two outputs summed and fed to amplifier 145. The curve associated with this amplifier represents the transfer function of the whole circuit. The level of the constant portion of this curve is determined by the setting of feedback potentiometer 158. The signal 1/K from generator 26 is fed to divider-multiplier circuit 40 which may be of the same type as the circuit 20 mentioned above. The circuit 40 also receives a signal corresponding to P c  from transducer 10, a signal corresponding to fuel flow F from meter 12 and amplifier 18, and a burner inlet temperature signal T b . The latter is formed by passing a constant current from a source 30 through a platinum resistance thermometer 13 to ground. The divider-multiplier circuit 40 forms the second term of the equation above and adds the turn T b  to give the required result.

Over the lower part on the outside of the tank, a layer of paraffin or other weakly adhesive cement may be applied, so as not to integrally bind the lower part of the tank to the shell, the area of adhesive being preferably less than one-third of the total surface. The shell may also include three equally-separated cushioning members made of a vulcanized soft rubber with at least 25 per cent of carbon black, but other tough and resilient compositions may be used.
