Title: Improvements in and relating to Gas Producers.
IPC: C10J3/34
Filed: 1918-08-12
Abstract: 125,932. Chapman Engineering Co., (Assignees of Chapman, W. B.). April 20, 1918, [Convention date]. Charging; charges, levelling.-Relates to means for levelling charges in a gas-producer, also to im. provements in fuel-feeding drums, in shoots, and in safety-devices for the driving-gear. Fig. 1 shows the upper part of a gas-producer with a rotating water-cooled agitator 49 driven by the toothed, ratchet, and other gearing 75, 82, &c., and worm gearing 81, 55. The feeding-drum 92 is rotated by means, with a safety-device shown in Fig. 3, which are connected to this driving- gearing, and the shoot has a shelf 87 and other fittings for evenly distributing the charge. The whole apparatus is carried by a pedestal 48 on a water-cooled ring 46. It is operated by a motor 73, which drives a pinion 75, eccentric rod 79, and ratchet-gear 82, the spindle 81 of which has a worm driving the wheel 55. Inside the hub of the wheel 55 are a pair of lugs 57 which engage with two spiral fins 53 on the shaft 5. When the agitator 49 is too deeply embedded in the fuel, the increased resistance to rotation causes the fins 53 to rise up on the lugs 57, and thus to lift the agitator in the fuel. Weights 58 may be varied to vary the distance within the fuel bed at which the agitator will be maintained. Cooling- water is supplied by a flexible pipe 59 to pipes 60, 61 in the shaft 51 and the agitator 49, and passes through these parts to nozzles 63, and thence to a reservoir 64 in the pedestal 48. Part passes through the pipe 65 to the ring 66, and part through a leg 69 to the bearing 70, and thence through two legs 71 to the chamber 46, and is drawn off by a pipe 72. The fuel-feeding apparatus comprises a drum 92, which is made slightly tapering to enable it to be moved axially in its casing 85, and thus to prevent the drum from sticking. This is effected by a device, shown in Fig. 4, consisting of a nut 94 which receives the end of the shaft 93 of the drum 92. When the nut 94 is retracted by means of the handle 95, the free end of the shaft 93 may be struck so as to dislodge the drum. In order to drive the drum, an adjustable crank 97, Fig. 3, is attached to the end of the worm shaft 81, so as to reciprocate a connecting-rod 98 with a safety-device, and by means of it a forked lever 99 which rotates the wheel 100 by means of a gripping-device 101. If desired, gearing 111, 112, driving a stirrer 109 - above the feeding-drum, may be fitted as shown. The safety-device referred to above comprises a connecting-rod 98 in two telescoping parts connected by a weighted lever 105, attached to the

Title: Improvements in or relating to die casting machines
IPC: B22D17/14
Filed: 1961-04-12
Abstract: 928,063. Casting-machines. DIE CASTING MACHINE TOOL Ltd., and A. R. MILLS. April 3, 1962 [April 12, 1961], No. 13198/61. Class 83 (1). In a pressure die casting machine with fixed and movable die plates 10, 11, respectively, the die evacuation means is in the form of an extraction pump 28 and reservoir 27 connected to the fixed die plate 10 via a solenoid-operated valve 25. The energizing of the solenoid 23 to open the valve 25 is effected by a micro-switch 22 on the movable die plate when the dies are closed. The evacuation of the die cavity 14 is co-ordinated with the position of injecting plunger 17 so that when the dies are closed evacuation is effected with plunger 17 positioned to close the entry port of pipe 21 to prevent molten metal being drawn through said pipe. The plunger is then withdrawn beyond said entry port for a predetermined time to permit a given quantity of molten metal 15 to be drawn into the injection cylinder 18 for subsequent discharge by the plunger into the die cavities. The forward movement of the plunger may also be time controlled in respect of the die opening, whereby said plunger may form a means of ejecting the cast article. The timing of the operation is controlled by a timing unit 30 which controls a change-over valve 20 of the plunger operating assembly 19 and the operation of die-closing cylinder 13. In a further embodiment of a goose-neck type a bypass passage is incorporated in the plunger to permit the replenishment of the injection cylinder so that said plunger need not itself entirely uncover the feed port from the molten metal reservoir.

IPC: G01C21/20
Abstract: 134,674. Wheelwright, J. S. Dec. 12, 1918. Plane-trigonometry calculators.-Relates to apparatus for calculating the speed, for least consumption of fuel, at which an aircraft should travel to make good a given course, for a known wind. The apparatus mechanically forms the diagram, shown in the figure accompanying the Provisional Specification, in which AB, the wind vector, makes the known angle with the vector BJ representing the course to be made good, and AC, AD &c. are vectors representing speeds of 25, 30 . . miles per hour. The speeds made good are therefore BC, BD .. in the desired direction. Perpendiculars CM, DN . .erected proportional to the fuel consumptions corresponding to air speeds AC, AD . . lie on a curve, the tangent to which from B gives a point O corresponding to the desired economic speed AE. The apparatus consists of a series of concentric quadrants 8 of radii AC, AD .. which can be engaged by slides 22 in a carrier 19 working in guides 18. The slides 22 carry other fuel-consumption slides 23 which can be adjusted according to graduations thereon and which would be clamped in such adjustment for a particular aircraft after experiment. The fuel slides have upturned projections 25 to engage a tangent arm 16 pivoted on a cursor 13 over the working edge of a wind arm 10, pivoted at the centre of the quadrants and having an index for setting against a divided arc 9. A spring clamp 15 holds the cursor in position. Off-set pieces 26, 27 on the uppermost slide 22 and carrier 19 respectively enable the carrier to be run up to bring both into contact with the tangent arm 16 simultaneously after the wind arm 10 and cursor 13 have been set. The slides 22 are then thrust into contact with the quadrants and the tangent arm swung into contact with the series of projections 25, of which the first to give contact corresponds to the quadrant, the speed on which will be the required economic speed. The pivot for the wind arm 10 is carried on an overhung bracket, as shown in Fig. 2.

Title: Hydraulic regulating system and apparatus
IPC: F15C3/12
Filed: 1964-04-01
Abstract: 1,057,707. Feeding webs. M. TAKEDA. April 1, 1964 [April 1, 1963], No. 13520/64. Heading B6B. [Also in Division G3] A hydraulic apparatus for controlling the position of a member such as the recentring of a moving sheet of material in response to lateral deviation comprises a jet nozzle 51 which cooperates with receiving passages 56, 57 leading to chambers 62, 63 at opposite ends of a spool valve 71. The valve 71 controls the supply and exhaust of fluid to the opposite sides of a piston 102 and the valve also has lands 81, 84 which co-operate with bleed passages 86, 87 of smaller diameter than the passages 56, 57. The jet 51 is moved by solenoids 41, 42 which are energized in response to lateral deviations of the sheet 107 which closes switches 108 or 109. With the valve 71 in its centred position, the lands 81, 84 throttle the passages 86, 87 to an equal extent. If the solenoid 41, say, is energized, the jet 51 moves against stop 46 and directs more fluid into passage 56 which causes valve 71 to move to the right against stop 76. This movement of the valve closes passage 87 and fully opens passage 86. However, since passage 86 is smaller than passage 56, part of the fluid returns out of the passage 56 and acts on the side of the conical jet surface 52 so that when the solenoid is deenergized, the fluid force acts to move the jet back towards a central position which causes flow into the passage 57 to recentre valve 71. In the central position, the forces acting on the conical surface are equal.

Title: Differential mechanism
IPC: F16H48/12
Filed: 1976-04-05
Abstract: 1533282 Differential gearing; positive clutches R KNOWLES 29 March 1977 [5 April 1976] 13736/76 Headings F2D and F2C A differential mechanism comprises a driving outer cage having end portions 22 provided with radiating driving teeth 26, a pair of axle shafts 20 each connected to a respective driven reaction member 32 (Fig. 5) having radiating teeth on each side and axially movable within the cage, there being an abutment member 30 between the reaction members 32 which has teeth which can mesh with those of the reaction members 32 and intermediate toothed plate members 40 which mesh with the driving teeth 26 and the driven reaction members 32, the intermediate plate members 40 and the abutment member 30 being splined to a ring 28 loosely mounted in grooves in the ends of the cage. In operation, should a driven reaction member 32 tend to rotate faster than the cage (e.g. the outside wheel of a vehicle negotiating a curve) the associated intermediate plate 40 will be moved axially into full contact with the driving teeth 26 and the driven member 32 will rotate slightly relative to the cage and move axially into engagement with the teeth of the abutment member 30 (which will also move axially towards the driven member 32). This process continues with the driven reaction member 32 being driven alternately by the intermediate plate member 40 and the abutment member 30 (driven via ring 28). The same process takes place with the other driven reaction member 32 which rotates more slowly than the cage. Drive is thus transmitted to both the outer and inner wheels with one rotating faster than and the other rotating slower than the driving cage. The cage may be driven through worm gearing. In an alternative embodiment (Figs. 17 to 24, not shown) a further toothed plate member is provided between the driving teeth 26 and the intermediate plate 40 and it is stated that this removes the need for an interaxle differential in a four-wheel drive vehicle by permitting movement of both the axle shafts of a differential in the same direction relative to the cage. In this embodiment the abutment member is in two parts urged apart by springs.

Title: Improvements in axial flow separator for a gas turbine engine
IPC: F02C7/05
Filed: 1966-03-29
Abstract: 1,122,953. Centrifugal separators. GENERAL ELECTRIC CO. 29 March, 1966 [31 March, 1965], No. 13755/66. Heading B2P. [Also in Division F1] Entrained particles such as sand and dust are removed from the airstream entering the compressor (13) of a gas turbine engine (11) Fig. 1 (not shown) by a separator 12 comprising vanes 25 which impart a swirl to the airstream and cause the particles to be directed into an annular chamber 31 formed between the outer casing 27 and a concentric inner wall 28. An annular porous foam filter 34 is mounted at the downstream end of chamber 31 to trap the entrained particles but to permit the filtered air to return to the mainsteam. The trapped particles are removed through a port (36) by a vacuum hose when the engine has been shutdown. Vanes 26 upstream of the compressor inlet guide vanes (18) remove the swirl imparted by vanes 25. Both sets of vanes 25, 26 are mounted on an inner fairing 21 and the vanes 25 may overlap circumferentially to ensure that swirl is imparted to the heavier entrained particles. In modifications. Figs 3, 5 (not shown), the profile of the outer casing (45, 45' respectively) of the separator is modified so that particles bouncing off the casing are directed into the annular chamber (49, 49'). A modified filter (50), Figs. 3, 4 (not shown) is pleated to increase the filter area. The separator may be combined, Fig. 6 (not shown), with a separator (60) of the kind described in specification 13308/66, the swirl imparting and removing vanes (61, 62) in this case being angularly adjustable to vary the swirl under different operating conditions. The separator 12 may be an integral assembly with the engine (11), the compressor inlet guide vanes (18) being omitted and the vanes 26 acting to direct the airstream on to the compressor rotor blades.
