Abstract: 706,325. Gas turbine plant. LUCAS, Ltd., J. Nov. 12, 1951 [Nov. 17, 1950], No. 28126/50. Class 110 (3). [Also in Group XXIX] Means for automatically controlling the supply of liquid fuel to a jet propulsion or gas-turbine engine in response to the difference of pressure between two points in the fuel supply passage and to the blower air pressure so as to obtain a desired control of the fuel-air ratio under all conditions of load including idling comprises a device responsive to the blower air pressure and consisting of a body part a containing a chamber divided into two compartments b, c, by a diaphragm (or piston) d one of the compartments b being open to blower delivery pressure and the other c to atmospheric pressure or to blower inlet pressure and an evacuated capsule e of smaller diameter than the diaphragm located in the compartment c and operatively associated with the diaphragm for controlling a fuel regulating device. As shown, the diaphragm and the capsule are connected by a stem f to which is pivoted one end of a lever g carrying a vent valve t which controls a servo-piston p. The latter is connected to a fuel throttling plug j controlling an orifice k between a fuel inlet m connected to a variable delivery pump h and a fuel outlet n connected to a burner i. The plug j is loaded by springs o attached to the lever g and the body part a. On an increase of blowerair pressure, the vent valve t is opened and also through the servo-piston p, the fuel throttle. The output of the pump h is controlled in accordance with the pressure drop across the fuel throttle, the fuel pressures on opposite sides of which act on a spring-loaded diaphragm w which actuates a lever 3 carrying a vent valve 5 which in turn controls a servo-piston 7 regulating the output of the pump.

Filed: 1937-10-15
Abstract: 496,609. Controlling aircraft. MARTIN CO., G. L. Oct. 15, 1937, No. 28136. Convention date, Dec. 16, 1936. [Class 4] In an aircraft having a slotted wing, the slot of which may be obstructed by a flap, differentially-operable mechanism is provided whereby the shutter is positioned to substantially fully open the slot when the wing flap is moved from its high speed position to a slight extent only. In one form, the flap 35, which is adapted to close normally the slot between an aircraft wing 30 and wing flap 31, is actuated through cables 52, pulley 53, lever 101, links 102, lever 103, shaft 104, lever 107, link 109, and a horn 108 mounted on the flap. The flap 31 is actuated through a link 105 connected to the lever 103. During initial movement, the link 109 approaches the lever 107, the pivot 111. approaching the shaft 104 to substantially nest the flap 35 against the rear edge of the wings. The arms to which the flap 31 is pivoted are provided with stops. The pulley 53 may be operated from a handwheel, through irreversible worm-gearing, by an electric motor or by a hydraulic jack. In a modification, the flap 31, Fig. 3, is adjusted, on rotation of a crank 103, through a link 105. A pulley 54 is adjusted concurrently with the pulley 53 and, through a cam-slot 121, follower 124 carried by a lever 122 pivoted to the wing, a link 126, a lever 128, a shaft 130, a lever 129 and a link 127, actuates the flap 35. The angle through which the flap 31 moves before the flap 35 is nested may be determined by adjusting the relative sizes of the pulleys 53, 54. In a further modification, the cam-slot and follower are replaced by crank connected by a link to the lever 122. In this latter case the pulleys 53, 54 may be connected by a crossed belt or chain and a hydraulic jack pivoted at one end to the wing may actuate a crank on the shaft which carries the pulley 53. In a still further modification, the flap 31, Fig. 14, is adjusted on rotation of a pulley 151 through an arm 153, an arm 154 pivoted to a shaft 156, an arm 157 and a link 105. The flap 35 is adjusted, simultaneously with initial operating movement through pulley 158, arm 107, a link 109, a lever 160, a link 127 and a horn 108. An adjustable buffer 159 on the link 109 ensures closing of the flap 35 when the flap 31 is moved to its normal position.

Abstract: 432,180. Spray carburetters. CLAUDEL, C. H., Veuxhaulles, C¶te d'Or, France. Oct. 17, 1933, No. 28726. Void [Abridged as open to inspection under Sect. 91 of the Acts, April 18, 1934]. [Class 7 (iii)] The Specification which does not admit of satisfactory abridgment is concerned with a carburetter comprising two submerged jets Gr, Gc fed with light fuel and a submerged jet Gp fed with heavy fuel. During idling, mixture formed by light fuel from the jet Gr and air admitted at 3, is drawn through ducts 6, 6a to an outlet adjacent the throttle valve 39. The jet Gp supplies heavy fuel through a passage 8 to an emulsifying chamber, formed between tubes 9, 10, to which the engine suction is directly transmitted through orifices 20 whilst the jet Gc supplies light fuel through a passage 18 to a concentric chamber formed between tubes 10, 14 which communicate with the orifices 20 through holes 19 in the tube 10. Light fuel may also be led from the jet Gc through a calibrated orifice Ga and a passage Sa into the space between the tubes 10, 9 through the latter of which hot air is supplied. The emulsion is discharged into hot air admitted through the intake 22 and as the suction increases ball valves 25 are lifted to admit cold air through orifices 26 around the choke tube 21. The jets Gp, Gc may be controlled by valves 27, 29 and the fuel in use may be determined by a lever 33 actuated by a thermally-sensitive element 30 mounted on the inlet pipe 31. At starting, the air supplied through the Venturi 21 is controlled by a cone 35 adjusted manually or by a thermally sensitive element. In modifications (1) a thermally-sensitive device is provided which controls the fuel flow from the jet Gc by means of a needle valve controlling an air inlet ; (2) during the transition between starting and normal running as the throttle valve 39 opens it uncovers an orifice 40 Fig. 5, to permit mixture formed by light or heavy fuel from a jet Ga with air admitted at 45, to be drawn through a conduit 41. The orifice 40, Fig. 6 is formed eccentrically in a member 43 so that its position relative to the valve 39 can be readily adjusted. At starting, an orifice 48, Fig. 10 is opened by a needle valve 50 to supply additional mixture from the conduit 41 to the space above the throttle valve and air may be admitted past an opening 49 and (3) the jet Gc may be fed with heavy oil.

Filed: 1929-09-24
Abstract: 334,403. Electroflo Meters Co., Ltd., (Republic Flow Meters Co.). Sept. 24, 1929. Relay devices.-A relay and follow-up device for giving strengthened movement to indicating, controlling, transmitting and other apparatus comprises a feeling member 15 adapted to be periodically released by a push rod 5 actuated by an auxiliary force. The invention is shown as applied to register the results obtained from an automatic gas analyser comprising a bell 2 carrying a tappet head 4, which is periodically lifted to a height corresponding to a hew charge. The movements of the bell 2 and the rod 5 are synchronized so that after the bell comes to rest in its elevated position the rod 5 moves upwards, thereby depressing a lever 10 and lowering a loop 24 so as to release a pin 25 carried by a wheel 14. The shaft 13 of the wheel 14 is mounted on a lever 9 and carries the member 15, the contact screw 27 of which is thus allowed to move into contact with the tappet 4. Continuing its downward movement, the lever 10 grips the wheel 14 and locks it against further rotation. Further downward movement of the lever causes the floating lever 9 to swing round pivot 8 and the pins 16 on the wheel 14 to contact with and position a member 17 carried by a shaft 18, which is thus rotated an amount corresponding to the position of the bell and which performs an indicating or other function. For example, the shaft 18 may carry a contact arm adapted to co-operate with contacts or with a resistance element for use in electric apparatus for controlling or recording at remote points. A temperature-compensated tappet arm may be used in place of the arm 15.

Abstract: 500,446. Automatic control systems. MIJER, M. D., and EYKMAN, C.H. Oct. 26, 1937, No. 29227. [Class 38 (iv)] [Also in Group XIII] Humidity in a room is controlled by means of a single vessel 2 containing regenerable moisture - absorbing material 7 such as silica gel and including a fan 4 and a humidostat (not shown) controlling it, a heater 11, a two-way valved outlet 9, 10, and a control device 18 which actuates the fan, heater, and valve after rendering the humidostat inactive. When the humidity is excessive the humidostat causes the fan to pass the room air through the dryer and back into the room through outlet 9. At regular intervals however, a regeneration period is established by device 18 consisting of a clock switch operating the fan irrespective of the humidostat, closing outlet 9, opening outlet 10 to the outside atmosphere and at the same time switching on the heater, so that heated air passes through the material and is discharged from the room. In another embodiment regeneration is initiated and terminated by means of a second humidostat affected by air issuing from the dryer and constituting the control 18. A timing device may retard the re-opening of the conduit into the room after a regeneration period until the air has been sufficiently cooled, i.e. after the lapse of a preferably adjustable interval or by means of a thermostat.
