Patent GB-1029603-A (GB)
Title: Improvements in flow control valves
IPC: F02K3/10
Filed: 1965-02-25
Abstract: 1,029,603. Valves. GENERAL ELECTRIC CO. Feb. 25, 1965 [Feb. 27, 1964], No. 8132/65. Heading F2V. [Also in Division F1] The invention relates to a reheat fuel control of a gas turbine jet engine and particularly to a flow control valve in the fuel supply line of a reheat pilot burner system. In the gas turbine jet engine of Fig. 1 (not shown) fuel passes through line 20 to the burners 19 of the main combustion equipment, Fuel may also be supplied from the supply 27 to the reheat burner nozzles 30 by way of pump 35, reheat fuel control 32 and line 30. When reheat is switched on, fuel under pressure is directed by valve 34 through line 38 to the pilot burner valve 39 which causes fuel to be discharged through line 41 to the pilot burner nozzle 42 in the reheat combustion section where the fuel is ignited thus providing a pilot flame for the fuel supplied to the main reheat fuel burners 30. The pilot burner valve 39 is shown in Fig. 2 and comprises a housing 46 which forms a cavity 50 in which is disposed a piston 51. The housing 46 is formed with an inlet 47 to which is connected a line 40 leading from the fuel line 20 to the main combustion section 14, an inlet 48 to which is connected the fuel line 38 leading from the valve 34 of the reheat fuel system, and an outlet 49 which leads through line 41 to the reheat pilot burner 42. In normal engine operation the valve is disposed as shown in Fig. 2 in which the piston 51 is biased by the spring 57 to the left so that the extension 58 of the piston bears against the valve seat 59 to close off the outlet to line 41. No fuel pressure is applied in line 38 so that the chamber 50c is vented to atmosphere. Fuel pressure in the line 20 is communicated through line 40, filter 55 and restrictor assembly 56 to the chamber 50a at the right-hand side of the piston 51. This fuel passes through the bore 61 in the extension 58 of the piston, through openings 62 to the chamber 50b which is sealed at the valve 59. When reheat is switched on fuel under pressure passes through line 38 to the pilot burner valve 39, through inlet 48 to the compartment 50c at the left-hand side of the piston 51 whereupon the piston moves to the right and fuel in the chamber 50a is forced through the bore 61 and openings 62 into the chamber 50b and from there through the valve 59 which is now open to the line 41 and so to the pilot burner 42 of the reheat combustion equipment. Fuel will also pass from the line 20 (which leads to the main combustion section) through line 40 to the chamber 50a and thus through line 41 to the pilot burner 42 as long as piston 51 is held to the right by fuel pressure in chamber 50c. Fuel will simultaneously flow through line 33 to the reheat fuel control 32, through line 31 to the main reheat burner 30. When reheat is switched off, the chamber 50c is vented to atmosphere through line 38, the piston 51 is moved to the left to the position shown in Fig. 2 and the chamber 50a is re-filled ready for the next reheat operation.

Title: Improvements in or relating to friction clutches
IPC: F16D13/71
Filed: 1938-03-16
Abstract: 493,748. Friction clutches. BORG & BECK CO., Ltd. March 16, 1938, No. 8188. Convention date, Aug. 26, 1937. [Class 80 (ii)] In a plate clutch, engaging pressure is transmitted to the pressure plate 4 from springs 15 housed in the driving flywheel 2 through force-multiplying levers 14, each lever being pivotally mounted on a bracket 13 secured to the flywheel and being subjected to the pressure of the spring 15 at a point radially outwards from its fulcrum, while the lever is in engagement with the pressure plate, through a roller 27, at a point radially inwards from its fulcrum. The inner ends of the levers co-operate with a sleeve 45 which can be moved to disengage the clutch, the plate 4 being urged to disengaged position by light springs 6. Each bracket 13 is of U-shape, being secured to the flywheel by a single screw 16 and positioned by a projection 17 engaging a recess 18. The sides of the brackets engage between lugs 47 on the plate 4, so as to provide a driving connection between the latter and the flywheel. Each bracket 13 carries a pair of spaced levers 14, the common pivot pin 22, fitted with a spacing sleeve 24, engaging in enlarged holes 19 in the sides of the bracket so as to afford a rolling fulcrum. A single roller 27 co-operates with each pair of levers, being positioned in recesses 26 in the levers and engaging a flat surface 28 on the plate 4. The lugs 47 prevent endwise displacement both of the rollers 27 and of the pins 22. A pair of springs 15 associated with each bracket transmit pressure to the pair of levers through a common strut member 37. The latter passes through slots 38 in the sides of the bracket, so as to limit its movement, and has an enlarged part 42 serving to space the levers and to prevent endwise displacement of the member 37. In a modification, stamped sheet-metal levers are employed, each lever co-operating directly with a single spring and having a pivot pin engaging an enlarged hole in a lug projecting through a slot in the lever from an individual bracket secured to the flywheel. In this form, the driving connection between the pressure plate and the flywheel is afforded by a radial projection on the former engaging a groove in the latter.

Title: Continuous distillation retort
IPC: C10B7/00
Filed: 1936-03-30
Abstract: <PICT:0457960/III/1> A retort for the distillation of solids impregnated with mineral oils, or liquids such as crude petroleum, or for the cracking of liquid hydrocarbons, comprises a rotating drum of spiral formation between the spirals of which the material passes while it is heated externally, or internally by contact of hot gases, or by both these methods.  The material is fed from a hopper 12 by a screw conveyer through a duct 3 leading to the centre of the spiral metal sheets 2.  Burners 10 supply heating gases which pass partly around the rotary drum to a stack 13, and partly between the spirals and in contact with the charge, the distillates escaping through ports 5 into a receiver 6 and outlet passages 7, 8, an exhauster 9 being provided.  The residue falls into an hydraulic seal 11.  The material passes in a thin layer over the metal plates which are of aluminium, nickel, copper, or an alloy thereof, steel sheets being used towards the outlet.  In Fig. 4 is shown a double spiral which enables the material to be heated if necessary without direct contact of the heating gases which pass through the spaces d, while the material passes through the spaces c, the spiral surfaces 2 and 20 being joined at the centre.  The heating gases pass through a receiver 22 communicating with a fan 24.  By adjusting the speed of fans 9 and 24, and the setting of the stack valve 14, the heating gases may be directed either outside the drum to the stack, or inside the spiral passages c or d, and these gases may be prevented from passing through the passages c.  The gases used for heating may be those produced by the distillation reheated and recirculated after removal of condensable products in a closed cycle, surplus gas being drawn off.  Steam may be admitted from an external source, or provided by generation from the water seal, and hydrogen may be produced by contact with the carbonaceous residue, the oils being hydrogenated during distillation.  The screw conveyer may be operated to supply material in excess of that used, the amount passing to the retort being controlled by a hit-and-miss valve.
