Title: Improvements in fuel supply systems for gas turbine engines
IPC: G05D16/06
Filed: 1955-07-08
Abstract: 799,936. Gas turbine jet propulsion plant. HOBSON, Ltd., H. M., and GREENLAND, L. S. April 27, 1956 [July 8, 1955], No. 19832/55. Class 110 (3). [Also in Group XXIX] A reheat fuel system for a gas turbine engine comprises a device sensitive to the compressor delivery pressure and to the turbine discharge pressure, a servo-mechanism controlled by the pressuresensitive device and arranged to vary the effective area of the outlet of the discharge pipe of the engine, so as to eliminate the back pressure produced in the discharge pipe by combustion of fuel supplied to the after burner, and an override device to reduce the supply of fuel to the after burner and arranged to be actuated by the servo-mechanism when the area of the outlet from the discharge pipe has reached its maximum. In an embodiment, the pressure-sensitive device comprises a diaphragm 10 with turbine discharge pressure acting on its right-hand face and compressor delivery pressure admitted past an adjustable needle valve 15 acting on its lefthand face. Compressor delivery pressure is exhausted through an orifice 16 controlled by a profiled valve 17 carried by the diaphragm. An increase in discharge pressure from the turbine causes the diaphragm 10 to move to the left, rocking a lever 18 and displacing a control valve 19 to cause movement of a servo piston 21 to the right. This movement through a link 22 displaces the control valve 23 of a second servomotor 24 causing the servo piston 25 to move to the left to increase the area of the outlet of the discharge pipe. Valve 23 is returned to its neutral position by the follow-up link 22. Valve 19 is returned to its neutral position by a return of the diaphragm 10 to its original position by a build-up of pressure on the left-hand side of the diaphragm due to a reduction in the area of the orifice 17 and also by a reduction in pressure on the right-hand side of the diaphragm due to the reduction in turbine discharge pressure caused by the increase in discharge pipe outlet area. As the servo piston 25 moves to the end of its travel corresponding to maximum area of the engine discharge pipe outlet a rod 44 secured to servo piston 21 approaches the pivot point 38 of a manual operating lever 37 controlling a valve 32 for varying the amount of fuel passing to the after burner and finally displaces the lever 37 to reduce the flow of fuel to the after burner. Downstream of the valve 32 a pressure regulator valve 33 is provided to maintain the pressure drop across the valve 32 equal to that across a fixed valve 29 in the fuel supply line to the main burners.

Title: Separating apparatus

IPC: B04C3/00
Filed: 1965-05-11
Abstract: 1,079,774. Centrifugal separators. SIEMENS-SCHUCKERTWERKE A.G. May 11, 1965, No. 19926/65. Heading B2P. In a separator of the type described in Specification 933,224, for separating particles from aerosols, a member or members disposed on the axis of the separating chamber defines /define a flow path for the aerosol entering an inlet at one end of the separating chamber which flow path diverges and then converges a plurality of times as seen in the axial direction from the separating chamber inlet to an outlet at the other end of the chamber. As shown in Fig. 1, the aerosol is introduced through an inlet pipe 3 which may be provided with one or more whirl-producing guide plates 17. Auxiliary gas is introduced through oblique tangential nozzles 4 to create a potential flow. A flow control member 2 on the axis of the separating chamber 1 and coaxially disposed directly above the pipe 3 has progressively widening and narrowing smooth surfaces 9, 11 following one another in an axial direction. The member 2 prevents the very finegrain particles from passing straight through the chamber directly through the outlet 8 for the purified aerosol gaseous carrier medium, the divergent surfaces 9 of the member and the change of direction imparted to the aerosol flow at the point of inflection 10 serving to promote the separation of these particles. In a modification; Fig. 2 (not shown), flow control members are provided by means of internested funnel-shaped hollow members 12 having throat apertures 15 directed axially towards the aerosol inlet 3 and each extending into the outlet aperture of the preceding funnel and the last into the mouth of the inlet 3. A solid funnel-shaped member 13 forms the upper flow control member. At the edges 14 of the members 12 are formed eddies into which a proportion of the fine suspended particles enters; these particles may be sucked away through the throats 15 by means of negative pressure applied at the throat of the lowermost funnel 12. A helical guide 16 is provided on the outer side of the lowermost funnel to impart a preliminary spin to the aerosol stream.

Abstract: 905,497. Hydraulic apparatus. TOS RAKOVNIK NARODNI PODNIK. June 7, 1960 [June 8, 1959], No. 19996/60. Class 69 (2). [Also in Group V] Apparatus for controlling the movement of hydraulic pistons 18, 20 in a predetermined order comprises a filling and discharge valve 1 operated by a piston 2 in a cylinder 27 connected by a valve 10 to a source of fluid pressure a or to exhaust c, a spring-loaded main control valve 3 having a piston 5 co-operating with a movable stop 7 for controlling the position of the valve 3, the space 11 on one side of the piston being connected to a chamber 12 in the cylinder of the piston 18, and the space 13 on the other side of the piston 3 being connected by a valve 9 to the source of fluid pressure or to exhaust, the closing of the valve 1 towards the end of the stroke of the piston 18 effecting a rise in pressure in the chamber 12 to move the control valve to a position wherein the source of fluid pressure is connected to the cylinder 26 of the piston 20. The apparatus may form part of an injection moulding machine, the piston 18 effecting the opening and closing of the mould, and the piston 20 pressing the molten material into the mould. When the valve 9 is moved from its position shown to connect the space 13 to exhaust, the valve 3 is urged by the spring 4 to a position abutting the stop 7 which is retained in its left-hand position by fluid pressure supplied to a chamber 14. Fluid pressure from a line a is then connected by the valve 3 to a chamber 22 to move the piston 18 to the right to close the mould. Shortly before the piston 18 reaches its extreme right-hand position, the valve 10 is actuated to connect the cylinder 27 to exhaust and close the discharge valve 1, resulting in an increase in pressure in the chamber 22 which opens a by-pass valve 23 to admit the pressure to a chamber 12 and apply increased pressure to the mould. The pressure in chamber 12 also acts in the space 11 to move the piston 5 and the stop 7 to the right, the resulting movement of the valve 3 connecting the fluid pressure from the line a to the cylinder 26 of the piston 20 to inject the molten material into the mould. When the valve 9 is returned to the position shown, fluid pressure is connected to the space 13 to move valve 3 back to its initial position so that the cylinder 26 and chamber 22 are connected to exhaust. Piston 18, however, remains in its right-hand position until valve 10 is operated to re-connect cylinder 27 to supply open valve 1, the piston 18 then being retracted by the permanent pressure from the line a connected to a chamber 24.. The valves 9, 10 may be operated by electrical pulses from relays, limit switches, or press buttons.
