Title: Improvements in or relating to an electric drive mechanism for a machine, such as a nut former or the like
IPC: H02K7/10
Filed: 1955-05-18
Abstract: 775,330. Electric motor driving arrangements. WATERBURY FARREL FOUNDRY & MACHINE CO. May 18, 1955 [May 24, 1954], No. 14336/55. Class 35. The crank-shaft 11 driving the gate of a nutforming machine is secured to a gear-wheel 12 engaged by a pinion 13 fixed to a jack shaft 14 upon which a pulley 17 is freely mounted, this pulley being adapted to be clutched to the shaft 14. A main motor 20 drives the pulley 17 through belting 18 and its shaft is extended to an air-operated clutch 21 by which the motor shaft may be secured to the shaft of a gear reduction unit 23, this unit being driven in turn by a reversible auxiliary motor 25. Thus, when the main motor is de-energized the auxiliary motor may drive the shaft 11 at low speed so that it may be inched in either direction in order to set up the tools of the machine. The motor 25 may also be used for slow starting, for overcoming the initial inertia before the main motor is energized to drive the mechanism at its normal operating speed. When a valveplunger 46 is in the position shown, a pipe 32 is in communication with line 50 so that air is supplied through conduit 31 to an inflatable clutch member 28, whereby pulley 17 and pinion 13 are clutched together. A pipe 42 communicates with pipe 51 through the valve in this position but the actuating member 39 of an air-operated brake is not effective unless pedal 54 is depressed. Actuation of an emergency push-button energizes solenoid 55 and the plunger 46 is moved to the right so that line 32 is connected to vent 45 and the clutch is released, permitting the pulley 17 to rotate idly on the shaft 14. At the same time, pipe 42 is connected to pipe 49 and the brake is set.

Title: Improvements in or relating to fuel feed systems for gas turbine engines
Inventor: DAVIES JAMES FRANCIS ARTHUR
IPC: F02C9/16
Filed: 1959-04-27
Abstract: 919,077. Fluid-pressure servomotor control systems. BRISTOL SIDDELEY ENGINES Ltd. April 27, 1960 [April 27, 1959], No. 14336/59. Class 135. [Also in Group XXVI] The fuel supply system of a gas turbine engine having a compressor comprises a variable delivery pump 3 supplying fuel to the burners 4 through a pipe 2 having an adjustable throttle 1. The pump delivery is controlled by a piston 7 of a servomotor 6, loaded by a spring 9 and subjected to pump delivery pressure through a pipe 10 from which leads a passage 11 containing a constriction 12. The pump delivery is normally controlled by a first barometric pressure control unit 16 comprising a valve 15, controlling a vent from the right-hand side of the piston 7, carried by a lever 17 supported by a flexible diaphragm 18 which divides the unit 16 into two chambers 19, 23. The chamber 23 is connected by a pipe 24 to the air intake of the compressor, which pressure may be either static or ram pressure, and an evacuated bellows 25 in this chamber acts on the lever 17. A piston member 21 also acts on the lever and is loaded by the fuel pressure between the pump and the throttle valve. The control 16 thus acts according to a law determined by the setting of the throttle 1. A second barometric control unit 26, similar to 16 but loaded by the fuel pressure between the throttle and the burners can also control the servo 6 when a valve 29 in the pipe 14 is opened. The valve 29 is opened when an event, liable to cause surging of the compressor, is anticipated. This valve may be opened by a signal produced by minor flow disturbances in the compressor which precedes stalling or as shown by electrical means. The valve 29 comprises a closure member 33 controlled by an auxiliary electromagnetically actuated vent valve 36. The current to the magnet is controlled by a switch 39 which also controls the circuit to a gun firing actuator 41. Firing of the guns disturbs the engine tending to cause compressor surge, but this surge is avoided by the control 26 being brought into action. Preferably there is a slight delay on the firing of the gun until after the valve 29 has opened.
