Title: Improvements in or relating to fuel systems for gas-turbine engines
Inventor: MATTHEWS ROBERT BARRY
IPC: F02C9/16
Filed: 1962-03-06
Abstract: 1,041,213. Gas turbine engine fuel systems. PLESSEY CO. Ltd. March 6, 1963 [March 6, 1962], No. 8496/62. Heading FIG. The invention relates to a fuel system for a gas turbine engine of the kind having an aerodynamic compressor. Fuel is supplied from a tank to the inlet 1 of the control unit and it is then passed through the gear pump 2 to the duct 3, the output of the pump being proportional to engine speed N. The fuel then passes through a control valve 6 which is a sleeve valve formed with apertures 5 which co-operate with a fixed port 4 to form a variable area orifice, the axial position of the sleeve being controlled in dependence on the compressor intake temperature T 1  sensed by the capsule 28 which acts on the S-shaped Bourdon tube 7. The apertures 5 are shaped so as to present an orifice the area of which is proportional to #T 1 . The fuel then passes through a duct 9 to a chamber in which is disposed a sleeve valve 10 formed with apertures 12 which co-operate with a fixed port to define a variable orifice. One side of the valve 10 is acted upon by pressure of fuel upstream of the orifice 5 and the other side is acted upon by pressure of fuel downstream of the orifice 5 so that the axial position of the valve 10 is proportional to the pressure drop across the orifice 5 and therefore to N/T<SP>2</SP>. The fuel then flows to chamber 14 and then passes by way of recesses 15 in a valve member 16 to the outlet 18, the recesses 15 co-operating with the stationary duct 17 to define a variable area orifice. The axial position of the valve 16 is controlled in dependence on compressor intake pressure Pi by means of a capsule 19 disposed in chamber 20 which is connected to pressure Pi by means of duct 21. The pressure drop across the orifice 15, 17 is arranged to be made equal to that across the orifice 12, a differential link valve 23 being provided for this purpose, the valve having a face of relatively large area which is acted on in one direction by pressure in the chamber 14, i.e. the pressure in the space between the orifices 12 and 15, 17, and two faces each having an area equal to half that of the relatively large area, the two small areas being acted on in the opposite direction by the fuel pressure in the duct 9 and the fuel pressure in the delivery line 18 respectively, the latter pressure being communicated to the valve 23 by way of duct 22. The valve 23 is formed with apertures 24 whereby fuel in the chamber 14 may pass back to the suction side of the pump 2, thus maintaining the pressure drop across the orifice 12 equal to that across the orifice 15, 17.
Patent GB-350949-A (GB)
Title: Improvements in or relating to folding mechanism
IPC: B65H45/16
Filed: 1930-03-17
Abstract: 350,949. Paper-folding machines. HOE & CO., Ltd., R., QUICK, C. G., and WHITEHEAD, W. A., 109, Borough Road, London. March 17, 1930, No. 8581. [Class 100 (ii).] In paper-folding mechanism in which the sheet is tucked by a blade 19 between gripper jaws 4, 5, the jaws are operated by a toggle-lever mechanism adapted to be moved into dead centre position to cause the jaws 4, 5 to grip the paper. In one form, as shown in the Figure, the jaw spindles 27, 30 are geared together and are operated by means of toggle levers 23, 24, the shaft 22 of the lever 23 carrying an arm 21 having a roller 11 running in a cam groove on the cylinder 1. When the levers 23, 24 are moved into straightened position to close the jaws 4, 5, the cam groove is relieved of the direct pressure required to hold the jaws closed and the wear thereon is therefore reduced. In order that the gripping action may be resilient, the lever 24 passes freely through a swivelling block 25 on the jaw 4 and springs 16 on the lever bear against the block 25 and an adjustable stop on the lever. In a modified form, the arm 21 is dispensed with and the roller 11 is situated at the joint of the levers 23, 24. The resilient connection 16, 25 is omitted but a spring-pressed rod is provided tending to keep the jaw 5 pressed against the jaw 4, which is provided with a cam part engaging the jaw 5 so that both jaws are opened simultaneously by the toggle mechanism against the spring action.
Patent GB-656731-A (GB)
Title: Improvements in machines for exchanging the bobbins in and threading lace machine carriages
IPC: D04C5/00
Filed: 1948-03-24
Abstract: 656,731. Lace-making. JARDINE, Ltd., J., SWINDALL, J. W., ROSTANCE, J., and NISBET, J. March 24, 1948, No. 8590. [Class 74 (i)] In a machine for exchanging the bobbins in and threading lace machine carriages, the shaft which is connected to the carriage carrier is frictionally connected to and driven by a member which is itself driven from the machine mainshaft and is positively advanced at intervals. The main shaft 11 of the machine drives the shaft 2 of the carriage carrier 1 through gearing 12 and a plate 9 bearing a pin 8 which engages, at succeeding revolutions, in successive radial slots 7 in a plate 6 secured to a member 4 loose on shaft 2 and frictionally connected to a plate 3 on the shaft. A cam 13 engages in recesses 14 in the periphery of the plate 6, to lock it in position between successive steps. During each revolution of a disc 25, which rotates once for each motion of plate 3, a detent lever 18 is raised into the path of stops 19 on the underside of plate 3, but is normally allowed to fall before it engages a stop. The lever is raised, through linkwork 17, 16, 20, 21, 23, by a high part on the disc, which rocks the lever 23 clockwise, Fig. 4; the low part 27 of the disc permits the lever 18 to drop. If too many bobbins accumulate in the empty bobbin magazine 15, the upper bobbin in one of the tiers thereof will engage a roller 28 and hold the arm 16 raised, to stop the machine. If an empty bobbin is not removed from a carriage, a finger 29 is prevented from passing through an opening in the carriage and the detent 18 is again held raised. If too many threaded carriages accumulate in the magazine, a pivoted arm is raised by engagement therewith and a link trips a catch-lever which holds the starting lever in its "starting" position. Specification 424,704 is referred to.

Filed: 1960-03-11
Abstract: 914,968. Lubricating. KING Ltd., GEORGE W. March 2, 1961 [March 11, 1960], No. 8662/60. Class 12 (3). A lubrication system suitable for endless chain-type conveyers comprises a lubricator 14 connected by pipes 22 and 23 to nozzles 24 and 25 respectively, which are mounted on pivoted arms 26 and 27 disposed one on either side of the conveyer track 13. By movement along the track, the trolley 12 makes contact with the arms 26 and 27 which are caused to move through a horizontal arc which permits the nozzles to register, make pressure of springs 30 and 31, in the oil hole of the trolley wheel spindle. Lubricant is supplied by means of air pressure as the nozzles reach the mid-arc position when the striker collar 32 contacts a microswitch 21 which operates solenoid valves 16 and 17 controlling the air supply to the lubricator 14. Having passed the operating position the arms and nozzles are returned to their original positions by the return springs 33 and 34. A further embodiment comprises a pneumatic means of moving the nozzle units transversely to the conveyer track for use with short pitched trolley units. Alternative airoperated valves may be used in place of the electrically-operated described.

Title: Two-stroke internal combustion engines having free-running turbosuperchargers
IPC: F02D9/00
Filed: 1961-03-09
Abstract: 896,659. Regulating; charging two-stroke engines. SULZER FRERES S.A. March. 9, 1961 [March 15, 1960], No. 8737/61. Classes 7(2) and 7(6). [Also in Group XXIX] The supercharging pressure of a two-stroke engine having at least one free-running turbosupercharger 9, a speed regulator 48, and means for adjusting the pre-exhaust angle, is regulated by adjusting the pre-exhaust angle in combined dependence on the instantaneous actual engine speed and on the speed regulator setting so that the pre-exhaust angle is increased with a reduction in engine speed and vice versa and so that the pre-exhaust angle is increased when the speed regulator setting rises above the actual engine speed and vice versa. A gear-type pump 32, driven from the cam-shaft gear train 24..29, supplies oil under pressure to the underside of a spring-loaded piston 37 through a pipe 33 past a sharpedged metering orifice 34 so that the delivery pressure varies approximately as the square of the speed of the crank-shaft 4. Movement of the piston 37 causes tilting of a normallyhorizontal lever 40, connected at one end with a hand-setting lever 46 for the speed regulator 48 and at the other end with the control valve 60 of a servo-mechanism 52. The lever 50 controls a fuel injection adjusting device through a rod 51. The control valve 60 throttles the escape, through an orifice 58, of a pressure medium which is fed from a conduit 53 through a throttle bore 55 in a stepped piston 54. Closing of the orifice 58, by the valve 60, causes a rise of pressure on the underside of the piston 54 which is moved upwardly or vice versa when the orifice 58 is opened. Movement of the piston 54 causes rotation of a lever-mounted journal 30, carrying idler gear-wheels 27, 28 around the axis of a cam-shaft 23 to effect angular displacement of an exhaust valve cam 17 with respect to the angular position of the crank-shaft 4 by differential rotation of the gear-wheel 29 which is fixed to the cam-shaft 23 and the freely rotatable gear-wheel 26. The functional relationship between the speed and the magnitude of the pre-exhaust angle may be a continuous or discontinuous ratio e.g. by using a spring 36 having a non-linear characteristic or by initially loading a soft spring 36 and providing a stop pin 70 on the piston 37.
