Title: An improved fuel-feed regulating means in gas-turbine propulsion units
IPC: F02C9/16
Filed: 1960-04-22
Abstract: 919,542. Fluid-pressure servomotor control systems. DAIMLER-BENZ A.G. April 22, 1960 [April 24, 1959], No. 14231/60. Class 135. [Also in Group XXVI] In an hydraulic servo-system for regulating a gas turbine fuel supply the fuel supply valve 40 is actuated by a spring-loaded piston 38 controlled by a control valve 14 acted on by speed-responsive means 15 and, upstream of the piston 38, there are acceleration-limiting and deceleration-limiting valves 28, 32 respectively. The control valve 14 is loaded by a spring 13 adjustable by a lever 11 through a cam 12. A capsule stack 26 responds to a compressor pressure and to burner temperature to control a pilot valve 22 within a servo-piston 18, the rod 18<SP>1</SP> of which is connected to one end of a lever 31, the other end of which is received by a notch of a rod 41 extending from the fuel supply valve. The lever 31 controls the valves 28, 32. In operation, if the lever 11 is moved to call for an increase in the fuel supply the control valve 14 moves to allow the pressure oil to pass via lines A3, A5, A6, A7 to the chamber 37 causing the piston 38 and the valve 40 to move to the right to open the supply port 46. The lever 31 is moved away from the rod 28<SP>1</SP> of the valve 28 which is moved by its spring to close the line A6. The resulting rise in compressor pressure causes shortening of the stack 26 and movement of the pilot valve 22 to connect chambers 51 and 52 to pressure oil supply and exhaust respectively so that the piston 18 moves to the left to return the lever 31 and move the valve 28 back to re-open the line A6 and allow more pressure oil to enter chamber 37. A piston 17 integral with the piston 18 expels oil from the chamber 16 to increase the movement of the piston 38 which stops when the speed reaches the desired value and the control valve is in the neutral position. If a decrease of speed is called for the valve 14 is moved to connect the chamber 37 to exhaust so that the spring 39 moves the piston 38 and the valve to the left to close the supply port 46. The lever 31 moves the valve 32 to close the supply line A7. The resulting fall in compressor pressure causes the stack 26 to expand so moving the pilot valve 22 and the piston 18 moves to the right to return the lever 31 whereupon the spring 34 moves the valve 32 to re-open the line A7. The temperature detector 55 by opening a relief valve in the line 49 to reduce the pressure in the chamber 25 prevents excess temperature. If a valve 53 is opened the chamber 37 is exhausted and the supply port 46 closed. A pressure regulator 47 is located in the excess fuel return line 47. A limiting speed regulator D comprising a pilot valve and a double-acting piston controls a valve in the fuel supply by-pass pipe 48. Specification 892,868 is referred to.

Title: Hydraulic brakes
IPC: B60T11/224
Filed: 1965-04-06
Abstract: 1,059,880. Fluid-pressure brakes; disc brakes. BELL AEROSPACE CORPORATION. April 6, 1965 [April 15, 1964], No. 14582/65. Headings F2E and F2F. An hydraulic brake master cylinder adapted for quick take-up of slack, particularly for supplying fluid to a disc brake acting on the rotor shaft of a helicopter, includes Õ stepped piston assembly which comprises a separately formed large-diameter piston 28 operating in a bore 24S and a small-diameter piston 30 operating in a bore 24T. The piston 28 is urged by a spring 70 against a conical portion 32T which is integral with both the piston 30 and a hollow member 32 guided in the bore 24S, which member enclosing a graduating spring 56 and plunger 34 via which force is transmitted to the piston assembly from a lever 36, coupled by a link 38 to the plunger. The lever is manually movable from the position shown to a position in which the link pivot 52 is overcentre (Fig. 2, not shown), whereupon conical portion 32T engages the piston 28 and fluid previously supplied by a reservoir 24 via port 39 is driven simultaneously both from chamber 46 to outlet pipe 14 and from chamber 42, via a pressure-limiting valve 48, to the outlet pipe, as shown by way of chamber 46. Valve 48 is arranged to close at a fairly low pressure, e.g. 50 p.s.i.g., sufficient for clearance of the pads 20, which is larger than normal to obviate the need for adjustment, to be taken up and the pads to be applied to disc 16 on shaft 18, coupled to the rotor shaft, after which pressure in chamber 46 rises much more steeply, this pressure acting via pipe 66 on a pistonoperated valve 64 whereby the combined effect of this and the sudden rise in pressure of the fluid trapped in chamber 42 opens the valve 64 to allow this trapped fluid to pass back to the reservoir. Valve 64 is arranged to open with, e.g. 64 p.s.i.g. pressure in the chamber 46, so that above this output pressure the pressure in chamber 42 drops to atmospheric, and the full effect of the smaller displacement of the piston 30, as compared with the initial combined displacements of the pistons 28 and 30, is realized. A pressure-relief valve 74 is provided in a bore of the piston assembly to set an upper limit to the output pressure. On brake release, fluid is returned from the reservoir, firstly via the valve 64 and, when the latter is closed, past the piston 28 via passage 40.

Abstract: 954,357. Grounded aircraft trainers. GENERAL PRECISION Inc. April 27, 1960 [April 27, 1959], No. 14786/60. Heading B7W. [Also in Division G3] In apparatus for controlling the cockpit movement of a flight trainer comprising piston- and-cylinder devices 92, 96 responsive to signals transmitted to valves 76, 78, a further piston- and-cylinder device 100 is provided to balance the weight of the cockpit. A supply line 52, which contains a check valve 110, a shut-off valve 54 and an accumulator 53, is connected to a constant pressure supply 50 having a return line 56. Connected across the lines 52, 56 are the two valves 76, 78 operated by control devices 64, 66 through shafts 68, 70, the devices 64, 66 being responsive to roll. and pitch signals, respectively, transmitted from the computer portions of a simulator 58. Each valve regulates the operation of one of the piston-and-cylinder devices 92, 96 for imparting pitching, rolling and yawing motion to the trainer. The piston-and-cylinder device 100 is also connected across the lines 52, 56, the line 52 leading to the space beneath the piston 104 via a shut-off valve 102 so that as the trainer rises or falls in use, the piston 104 which is attached to the trainer, will be similarly constrained to move. When the trainer rises fluid above the piston 104 will flow into the line 56 whilst further supply fluid will enter beneath the piston. Upon the trainer being forced downwardly the fluid below the piston 104 is subjected to considerable pressure some being absorbed by the accumulator 53 whilst some fluid flows past piston 104 to the exhaust line 56. An over pressure valve 108 may also be provided to release excess pressure into the line 56.

[Class 106 (iii).] Mixed time and distance drive.-In both clock and vehicle-driving mechanism back lash of the gear wheels is avoided by providing the mechanism with springs to urge the wheels into contact. The clock barrel 11 drives through gears 13, 14, 15 a wheel 16 loose on a shaft 17 but connected to a plate 18 carrying a ring 19 provided with inclined slots 20 housing spring-pressed rollers 23 which engage a disc 21 fixed to the shaft 17. The drive from the vehicle is through a worm engaging a worm wheel 27 loose on the shaft 17 and carrying a ring 25 also provided with slots housing spring rollers engaging the disc 21. The shaft 17 is thus driven from the road wheel or clock whichever is the faster, the other one overrunning. The shaft 17 is carried by a lever 29 pivoted on the axis 30 and pulled by a spring 31 so that the worm gear is in mesh. The worm 32 or its shaft is acted upon by a spring 34 so that it is pressed against the flanks of the teeth on the wheel 27 and a spring-pulled pawl 35 is provided which tends to turn the wheel 27 in the opposite direction to that in which it is driven. The pawl may be constituted by a strip of spring steel. The hub wheel 4 is freely mounted on the spindle 17 and is fast with a plate 4<1> formed with an arcuate slot 37 the effective length of which can be varied by a plate secured to the plate 41 by screws 39 which can be moved along a second arcuate slot 40 to cause the edge of the plate to blank off more or less of the slot 37. Into the latter extends a pin 41 fast with a plate 4<2> on the spindle 17. The hub wheel 4 is acted upon by a spring 4<1> in the direction of movement of the wheel which actuates a lever 3 operating the fare drum when the flag is down. The pin 41 to begin with is at the end of its slot due to the springing forward of the hub wheel 4, and at first moves idly in the slot for the period corresponding to the distance or time which is allowed for the initial charge. In a modification the one-way clutch devices are mounted on the parallel shafts instead of on a single shaft.

Title: Improvements in and relating to protective coatings
Inventor: GEMMER ERWIN
IPC: C09D5/46
Filed: 1958-05-09
Abstract: Epoxy resins cross-linked with low-molecular-weight polyamides, dicyandiamide, ethylene diamine or diethylene diamine, or modified with liquid polysulphide polymers are applied to surfaces by the fluidized-bed process in which the heated surface is contacted with a bed of particles of the resin fluidized by an ascending stream of gas.  When certain polyamides are used, cross-linking may proceed if the surface is cooled immediately after coating and kept for a period at room temperature; otherwise the coating may be further heated in an oven.  Examples of coating compositions include (1) epoxy resin (bis-phenol A/epichlorhydrin), and dicyandiamide for application to steel plates (2), (3), (4), epoxy resin and dicyandiamide for application to aluminium rods, (5) epoxy resin, aluminium oxide filler as an abrasive and dicyandiamide for application to steel plates, and (9) epoxy resin and polyamide (polymerized dilinoleic acid/ethylene diamine) for application to aluminium rods.  In Example (10) an aluminium rod is coated with a composition comprising 500 parts of a phenol-formaldehyde resin, 10 parts of silica and 1 part of a silicone resin.  Specification 807,238 also is referred to.ALSO:Articles are coated with a coherent layer of thermosetting material by heating the article to a temperature above the softening point of the material, contacting it with a bed of the said material fluidised by an ascending current of gas, and then curing the coating.  Suitable coating materials are phenolformaldehyde resins, urea - formaldehyde resins, unsaturated polyester resins, alkyd resins, melamine-formaldehyde resins, epoxy resins, and silicone resins, which may contain high melting-point fillers such as asbestos, slate, metal powders, pigments or abrasives; curing agents; thermoplastic resins e.g. cellulose acetate sulphate; or liquid polysulphide polymers.  A top coat of a thermoplastic material e.g. a polyamide may be applied while the thermosetting coating is still in a fused state so that mixing occurs.  The method is suitable for coating articles of iron, steel, aluminium, magnesium, copper, zinc, alloys thereof, glass, ceramics and wood.  The surfaces may be roughened e.g. by shot-blasting before application.  Examples are given of powdered coating compositions containing epoxy resin and dicyandiamide; epoxy resin, dicyandiamide and aluminium oxide; silicone resin; epoxy resin and polyamide; and phenolformaldehyde resin, silica, and silicone resin.  The article may be heated to a higher temperature after coating in order to cure the resin. Articles which may be coated include hand-tools, tubular sleeves, hooks, clamps, plating racks, anode hangers, ventilators, gears, pump housings, sieves, screens, switches, electrical fittings, tanks, protective caps, bushings, bellows, fan blades and guards. Examples describe coating plates and rods.  Specification 807,238 also is referred to.
