Abstract: 991, 531. Magnetic compasses. BENDIX CORPORATION. May 7, 1963 [May 7, 1962], No. 18059/63. Heading G1F. A remote compass signal transmitter 5, such as one in which a flux element supported by a pair of gimbals so as to be rotatable about mutually perpendicular axes has a permanent magnet associated therewith and mounted for rotation about the axis of the flux element and positioned in a plane parallel to that of the flux element, is secured to a ring 11 which is angularly movable on a bracket 35 secured to the wing or other part of the craft. After initially performing a compass swinging procedure on a compass rose marked off on the ground, the ring 11 is adjusted relative to bracket 35, as indicated by lubber line 45 parallel to the fore and aft axis of the craft and scale 40 on the ring 11, until the deviation is a minimum and bolts 29-31 are tightened to maintain this position. Should transmitter 5 need to be replaced, bolts 20-23 are released and stub shafts projecting from ring 11 ensure that the replacement transmitter is accurately centred relative to the ring 11 so that a subsequent compass swinging is unnecessary.

Abstract: 773,107. Water-tube steam boilers; regulating superheat. BABCOCK & WILCOX, Ltd. June 22, 1955 [June 22, 1954], No. 18073/55. Classes 123(2) and 123(3) In a water-tube boiler comprising a furnace 10 lined with'steam generating tubes which extend from a water drum 62 to a steam and water drum 60 and fired at a temperature above ash-melting temperature by rows of pulverised fuel burners 12, the molten ash passing through a slag tap 174 in the furnace floor 74 and the combustion gases passing through a gas outlet 14 into an open pass 16 in which they flow downwardly to a gas turning space 18 within a hopper bottom below the open pass and thence upwardly in a pass 20 locating successively secondary superheater tube-banks 22, 24, reheater banks 25...27, primary superheater banks 28...30 and an economiser 32 to discharge to the boiler stack through a flue 36 and air heater 38, superheat temperature is controlled by withdrawing cooled combustion gases from flue 36 through ducts 40...42 by means of a fan 44 which delivers the gas via ducts 46...50 to an inlet chamber 52 at the top of the open pass into which the gases flow through ports provided in the wall of the chamber. The rate of gas recirculation is varied as the load varies, for example in response to changes of steam temperature, steam flow and air flow in the manner described in Specification 675,410, to maintain the final steam temperature at a constant value. The recirculated gas also assists in preventing adherence of molten slag particles to the superheater surfaces by lowering the temperature of the gases in the downpass so that the particles carried by the combustion gas passing through outlet 14 solidify in downpass 16 and are deposited in hopper 18 from which they fall into a collection pit 112. Specification 526,825 also is referred to .

Abstract: 477,834. Pneumatic conveyers. HESSLING, W. June 30, 1936, No. 18194. [Class 78 (i)] Solid carbon dioxide in small pieces is transported, for example from the place of manufacture to a place of storage, by a current of gas of which at least one half consists of carbon dioxide. In the apparatus shown, the " dry ice " is made by a plunger press 8 and carbon-dioxide gas is admitted through an ejector 15, the carbon-dioxide gas being derived through a pipe 11 from the pipe 9 supplying liquid carbon-dioxide to the press. An independent supply may be given by the pipe 13 and an additional supply of gas may be given through a pipe 16. The dry ice is carried to a storage silo B from which it is conveyed by a screw 1 to another pipe 5 forming part of a closed circuit in which carbon dioxide circulates and communicating with a chamber C in which the dry ice is packed.

Title: Improvements in free piston gas generators
IPC: F02B71/04
Filed: 1945-07-17
Abstract: 595,878. Free piston gas generators. VICKERSARMSTRONGS, Ltd., and DAVIS, D. E. July 17, 1945, No. 18336. [Class 7 (i)] In a free piston gas generator of the type in which compressor pistons deliver during the working outward stroke of opposed combustion pistons in a common combustion chamber compressed air to be fed to the combustion chamber and having main pneumatic cushioning means which provide a cushioning action during the outward stroke and part of the necessary expansior. energy for driving the pistons on the inward stroke further pneumatic cushioning means are provided which form stabilising cushions which come into operation near the end of the inward stroke of the pistons to arrest them in the event of overstrokes at low gas pressures tending to cause the pistons in the combustion chamber to contact with each other whilst maintaining the compression pressure in the combustion chamber within the range required for efficient operation of the generator the stabilizing cushions being open to atmosphere and thus inoperative for the greater part of the inward and outward strokes. As shown opposed engine pistons 2, 3 having enlargements 7, 8 work in a common cylinder 1. The pistons 7, 8 compress air on each outward stroke in spaces 5, 6. At the rear of the pistons 7, 8 stabilizing cushioning spaces 5a, 6a, are provided. The main cushion spaces working during the outward stroke are arranged at 13, 14. The additional cushion spaces serve to prevent contact of the pistons when operating at reduced working pressure. Air is trapped in the cushions 5a, 6a when ports 15, 16 are covered by the enlargements. In a modification the positions of the compressor space and the main cushioning space are interchanged. In this case the enlargement of the piston works past a port in its cylinder which admits air to the cushion spaces on both sides of the piston.

The valve comprises a piston 19 held in a position closing the by-pass 17, 21 by electric energization thereof. On de-energization by the pulse generator a spring 20 causes the valve to open. The valve may be mounted in the pump body, the injector body or a separate body. A similar electromagnetic valve may be provided in the pump's suction line 8 whereby if the valve is closed before the piston 4 closes the line 8 the commencement of injection occurs earlier. The way in which a multi-cylinder engine is controlled by input signals representative of engine speed, torque or exhaust gas temperature or composition is described.

Title: An apparatus for using liquids, preferably for sanitary use
IPC: E03C1/00
Filed: 1949-07-12
Abstract: 659,966. Supply and waste fittings. KAMENETZKY, J. July 12, 1949, No. 18413. [Class 26] [Also in Group XXIX] Apparatus for using liquids comprises a portable sanitary appliance provided with liquid supply and drainage accessories, and a socket provided with intake and drainage conduits with which the sanitary appliance may be removably connected by means of a plug. As shown in Fig. 1 the wash basin 1 is provided with taps 4 and waste 5 each connected to the plug c by a flexible pipe 6, the plug c being shown as plugged into the socket b. The socket is provided with intake conduits 27, Fig. 13, for hot and cold water and a drainage conduit 35. Each intake is provided with a tap valve 10 having an axial bore 14 and fitted for rotary movement in the socket casing 8. Mounted on the face of the socket 8 are extensions within which are fitted cylindrical pistons 36. These pistons 36 are adapted to be pressed inwardly against spring pressure by means of the bored pins 52 mounted on the removable plug c. During this movement the intake valve members 10 are rotated through 180 degrees by means of a projection on the piston 36 co-operating with a cam groove on the valve member 10. In this position. shown in Fig. 13, the water coming down the conduits 27 passes through conduit 20 into an annular passage 16 and through the aligned bores of the piston 36, pin 52 and flexible conduits to the taps of the wash basin, the drain conduit shown in the lower part of Fig. 13 being open to the drain 35. In this position the parts, plug and socket, are held together by spring projections 48 engaging indentations on the bored pins 52. Partial withdrawal of the plug c to a position in which the projections 48 engage another set of indentations allows the pistons 36 to move outwardly so causing the tap members 10 to rotate through 90 degrees. In this position the liquid coming from the main conduits passes through bores 20, 25, through ejectors 15 or the tap members 10 and around a channel 22 to an ejector 31. This action withdraws any liquid remaining in the flexible intake and drainage tubes of the wash basin and complete withdrawal of the plug c causes further rotation of the tap members 10 to shut off the supply of water completely.
