Abstract: 438,951. Siphon-discharge waterwaste-preventers. MARSHMAN, G., and MARSHMAN, M. K., 4, Halvard Street, Bury. Feb. 24, 1934, No. 31505/35. Divided out of 438,878. [Class 26] In a siphon-discharge water-waste-preventer having a single siphon provided with two pullchains &c., the actuation of one of the chains &c. causes the siphon to discharge only a predetermined part of the cistern-contents, while in order to discharge the whole of the contents of the cistern, it is necessary to actuate the second chain &c. before said partial discharge is completed. In Fig. 1, a siphon primed by a piston 31 is surrounded by a chamber 27 hinged at 36 to a plate 34. When a lever 32 is operated, the siphon is primed to discharge only the liquid above and within the chamber, but if a lever 38 be operated before the completion of this discharge, the chamber 27 is tilted to permit discharge of the whole of the cistern contents. In another form, Fig. 5, the second lever closes a normally-open valve 46 disposed in the upper part of the pistoncylinder, the lever being jointed at 48 so that a downward pull on its outer end causes the lowering of the inner end to which the valve is attached. In a further form, Fig. 3, in which the siphon is of the moving-bell type, the second lever actuates a valve 53 in a wall dividing the cistern into two parts. Specification 438,878 is referred to.

Direct gas-pressure apparatus, non-automatic. -In the system described in the parent Specification, the liquid is raised from the intermediate tanks 2<1>, 2<2> to the storage tanks 1 by the inert gas under pressure instead of by means of a pump. The liquid is fed from the casks 9<1>, 9<2> through the pipe 8 and two-way cock 11, gas being meanwhile exhausted from the corresponding tank, namely 2<1> in the position of the cocks shown, by connexion with the exhaust side of the compression 4 through the piping 12. At the same time gas under pressure from the accumulators 5 is admitted to the other intermediate tank, i.e. 2<2> through the pipe 14. forcing the liquid up through one of the pipes 13 into one of the storage tanks 1, from which gas at atmospheric pressure is aspirated by the compressor through pipes 19 and 31, and forced into the accumulators. During delivery of the liquid from the tanks 1, gas expanded to atmospheric pressure by the expansion valve 6 is admitted through the pipe 33, cock 29, and pipes 19. A cylinder 28 of compressed gas serves to compensate for loss of gas due to solution in the liquid.

Title: Improvements relating to starting and ignition systems for gas turbine engines
Inventor: WEST HAROLD EDWARD WILLIAM
IPC: F02C7/266
Filed: 1952-12-12
Abstract: 740,090. Gas turbine plant. ROLLSROYCE, Ltd. Dec. 11, 1953 [Dec. 12, 1952], No. 31616/52. Class 110(3) A starter system for 'a gas turbine engine started by an auxiliary turbine supplied with combustion products from an independent combustion chamber, comprising electrical igniter means in both the main and auxiliary combustion chambers and a source of electrical energy for supplying both igniter means, has switching means for transferring said source from the igniter in the auxiliary combustion chamber to the igniter in the main combustion chamber at an appropriate point in the course of starting the gas turbine engine. To start the engine, a manual push-button 30 is closed. This energizes a relay coil 31 of a rotary time control mechanism having cams which close the contacts 32, 33 and 34 and allow the push-button 30 to be released. The closure of contacts 32 energizes a relay 35 which closes contacts 36 and thereby energizes the solenoids 37, 38. These solenoids open valves controlling the air and fuel supply to an auxiliary combustion chamber supplying combustion gases to a starter turbine. These valves are spring-loaded to the closed position. The closure of contacts 33 energizes the high tension supply apparatus 39 which is connected through the lead 40 to a switching relay 42. The armature 44 is biased by a spring 43 to make contact on a lead 26A feeding the igniter means in the main combustion chamber. The closure of contacts 34 energizes relay coil 45 causing the armature 44 to connect the lead 40 with the lead 25A feeding the igniter means in the auxiliary combustion chamber. After a predetermined time, the time control mechanism opens the contacts 32, 33, which causes the relay 35 and high tension supply apparatus 39 to be de-energized. The fuel and air supply to the auxiliary combustion chamber is then shut off. When the auxiliary turbine drives a compressor supplying combustion air to the auxiliary combustion chamber the solenoid 38 and the valve operated'by it may be dispensed with. In a mcdification of this arrangement the solenoid 38 may be replaced by an electric starting motor for the auxiliary turbine. The time control mechanism may be replaced by a centrifugally operated switch responsive to the speed of the auxiliary turbine, or by a temperature responsive switch responsive to the temperature of the exhaust gases of the auxiliary turbine. In a preferred arrangement, the time control mechanism is retained and the centrifugally operated switch or temperature responsive switch is arranged in series with the contacts 34 to de-energize the relay coil 45 and so connect the lead 40 with the lead 26A. An overspeed centrifugally operated switch driven by the auxiliary turbine may be placed in the lead between the battery and contacts 33 to shut down the auxiliary turbine when it reaches a preselected speed.

Abstract: 794,277. Spray carburetters. BENDIX AVIATION CORPORATION. Nov. 4, 1955 [Dec. 28, 1954], No. 31631/55. Class 7(3) A choke valve operatively connected to a lever 38 is urged open, when the throttle valve approaches the substantially closed position, by a yieldable means 48 having one-way connection with the choke lever 38 and operated by a lever 26 on the throttle valve shaft 20. The lever 38 is connected to a bimetallic coil which, at ordinary cold starting, moves it to an almost closed position shown in Fig. 4 in which it is held by an arm 52 thereon contacting the means 48 which comprises a torsion spring looped about the shaft 20 and moved to the position shown by a lug 50 on the lever 26 when the throttle valve is substantially closed. Below a predetermined temperature the bimetallic element overcomes the spring 48 and moves the choke valve to the completely closed position. A fast idle cam 30, loosely pivoted on shaft 32, is weighted by a projection 34 towards the slow idle position and is moved to the fastidle position, in which it co-operates with a lug 28 on lever 26 to limit the closing movement of the throttle valve, by a lug 40 on the lever 38 when the choke valve is closed. The choke valve is positively opened, when the throttle valve is opened a predetermined amount, by a lug 54 on lever 26 engaging an arm 56 of lever 38. Hot air, supplied to the housing 24, Fig. 2, of the bimetallic coil is passed through a connection 60 into chambers 62, 62<SP>1</SP>, in the carburetter body to prevent icing. A dashpot retards the closing movement of the throttle valve.

Abstract: 1,007,803. Electric selective signalling. CENTRE CIRCUITS Inc. Aug. 12, 1963 [Aug. 13, 1962] No. 31712/63. Heading G4H. [Also in Divisions B3 and G3] In a device for positioning a work-table or tool, coarse positioning is effected at high speed by sensing one of a series of longitudinally spaced and transversely off-set elements. As shown, decimal machine data is translated into a binary code and recorded on a punched tape, which is fed into a tape reader 108. A manual dial input device 110 is also provided. An air supply 112 is common to reader 108 and device 110 and their outputs are fed to a transfer valve and switch unit 114 supplying air to selected air lines 98, 116 leading to binary decimal gauges 42, 46 respectively. A programming console 118 controls the reader 108 through a connection 120, the unit 114 through a connection 122 and a drive control 36 through a connection 124. The operation of the drive control unit and unit 114 is monitored through feedback lines 126, 128 respectively. In operation, the gauge 42 is pneumatically actuated to position a light responsive device 40 transversely into line with a selected step of a profiled copper strip 58, embedded in transparent plastic 56 mounted on a movable work-table 10 of the machine. The output of the device 40, through the control unit 36, energizes a high-speed motor, not shown, to move the table 10 until the selected step interrupts a light-beam of the device. Positioning control is then switched to the binary gauge 46, actuated simultaneously with gauge 42, which positions a photo-responsive device 44 to a decimal portion of a step relative to a tube 52 in an opaque strip 54. The work-table is then moved to align the tube and device by a stepby-step motor, not shown, of the control unit 36. A decimal to binary gauge comprises a plurality of piston and cylinder units having throws proportioned in binary combinations 1, 2, 4, 8 so that ten decimal steps of a unit of travel, transverse or longitudinal, can be produced by selective actuation. The control unit 36 comprises a dial drive for a table lead-screw to the input shaft of which are clutched the high speed motor and the step-by-step final positioning motor. The system is applicable to more than one axis of travel. The course positioning can be effected by two stepped strips (see Fig. 3, not shown).
