Title: Improvements in or relating to the manufacture of water gas
IPC: C10J3/46
Filed: 1927-05-28
Abstract: 299,485. Nielsen, H., and Laing, B. May 28, 1927. Producers. -- A process of making water gas consists in first storing up heat in chamber containing brickwork or the like and then passing powdered carbonaceous materials and steam through the chamber. Air from a blower J and powdered fuel from a hopper H are supplied by a burner C to a combustion chamber A from which the hot gases pass through a reaction chamber B having tortuous passages formed by diamondshaped webs b<4> which permit any unconsumed carbon or ash to fall back into the chamber A. The chamber B is heated by the combustion products which pass to an outlet E leading to a steam boiler F. During gas making, steam from the boiler F is heated in passages D and passes with the powdered fuel into the chamber A and up through the heated reaction chamber B in which water gas is generated and from which it passes by the outlet E to a cyclone separator G and conduit g<2>. Any unconsumed carbon passes through a pipe g<1> to the main fuel hopper H. Two generators adapted to work alternately may be provided. The water gas may be used directly for distilling by internal heating bituminous materials for the production of towns gas. Air may be admitted with the steam whereby carbon dioxide and nitrogen are formed, the carbon monoxide present being converted catalytically to carbon dioxide in the presence of steam, hydrogen being set free. The whole of the carbon dioxide is then removed and a gas mixture containing 25 per cent of nitrogen and 75 per cent of hydrogen suitable for the synthetic production of ammonia, is obtained. Specifications 269,234, 276,407, 287,037 and 287,381 are referred to.

Abstract: 663,421. Mounting gramophone pick-ups. BRUSH DEVELOPMENT CO. June 3, 1949. [June 12, 1948] No. 14946/49. Class 40 (ii). [Also in Groups XXXIX and XL (b)] A phonograph pickup head comprises a moulded insulating base 12 in the underside of which are formed a main channel 17 ending in a constricted portion 16, and two side channels 21, 22. An elongated piezo-electric element 11 that operates by bending is accommodated in the channel 17 and has one end rigidly fixed by cement in the portion 16. The side walls of channel 17 serve to limit the lateral movement of the element 11. A stylus 32 is carried on a compliant spring arm 31 fixed by means of a yoke 29 on to the element 11. This avoids the transmission of shocks in a direction at right angles to the useful direction of bending. Electric leads 37, 38 connected to electrodes on the outer faces of the element 11, pass out through the side channels 21, 22 to connector plugs 23, 24. The head may be mounted on a tone arm by screws which pass through holes 26, 27 and also hold a cover in position. The bender element 11 may comprise two joined electroded plates cut from single crystals of piezo-electric material, or two plates of polycrystalline titanate material as described in Specification 648,404, [Group XXXIX]. Alternatively, as shown in Fig. 3, the element may be in the form of a flattened tube of barium titanate as described in Specification 663,423 [Group XL (b)]. The element may be strengthened by filling the ends with a thermosetting resin before they are cemented respectively to the recess 16 and to the stylus yoke. Damping pads may be placed in the channel 17. In setting up, the free end of element 11 is centred in channel 17 by means of jigs, and any inaccuracy in the shape of the element is taken up in the cement at 16. The pickup head may be moulded integrally with a U-section tone arm 44 shown in underside view in Fig. 7. The arm is pivoted at 47, and a shielded cable 54, held by spring clips 56, is connected by leads 37<SP>1</SP>, 38<SP>1</SP> to the electrodes on the piezo-electric element 11.

Abstract: 857,926. Latches. FINGSCHEIDT G.m.b.H., F. April 3, 1957, No. 14973/60. Divided out of 857,924. Class 44. Relates to a lock of the kind comprising a twoarmed forked latch member rockable about a fixed pivot in a casing adapted to be fastened to a door and which latch member by pivotable interposition of a rockable holder carrying an actuating spring is swivelled into the open unlocked position by a two-armed operating lever. According to the invention, one arm of the latch member is articulated to the spring holder in such a way that when the operating lever is swivelled away from the door, a short lever arm of the operating lever engages one arm of the forked member and swings the latter about its pivot, so that a pivot by means of which the forked member and the holder are articulated moves from a position on one side of a deadcentre position to a position on the other side thereof. As shown, a latch member 6 is pivoted between the limbs of a channel-shaped casing 1 secured to a door 4 and is also pivoted about a pin 9 to a spring-loaded holder 8 the other end of which is pivotally and slidably connected by a pin 12. The arrangement is such that as a handle 2 is moved away from the door about a pivot 3, the handle rocks the latch member 6 out of engagement with a keeper 7 against the spring 10 of the holder 8, to cause the holder to pivot and slide on the pin 12 which then engages a slide 11 to compress the spring 10 and maintain the latch member in the open position until it is rocked by the keeper 7 as the door is re-closed. The latch member may be locked in the engaged position by a locking device 15. The lock is secured to the door by means of a plate 17 screwed to the door and having studs which co-operate with key-hole slots 19 in the base of the casing 1. The plate 17 includes a bent-up part 171 by which the plate is also screwed to the casing.

Abstract: 810,200. Injection moulding machines. WINDSOR Ltd., R. H. Aug. 24, 1956 [May 25, 1955], No. 15069/55. Class 87(a). In an injection moulding machine, thermoplastic material, e.g. polystyrene copolymers, cellulose acetates, methyl methacrylates or the rigid vinyls, is forced under pressure from a horizontal injection chamber 13 into a vertical transfer chamber 10 : from there it is forced under greater pressure into a mould 23 by a ram 14, which is operated hydraulically. Hydraulic means for counterbalancing the reaction pressure of the ram are provided. The material is forced from the nozzle 3a of a plasticizing unit 3 along the chamber 13, which at each end carries ball and socket connections and through the lateral inlet orifice 12 into the chamber 10. On the injection stroke of the ram, the reaction pressure is absorbed by hydraulic pressure applied to pistons 20a and 21a in subsidiary cylinders 20, 21 and the transfer chamber opening 10a is thereby maintained in sealing engagement with the mould orifice 22. The transfer injection unit passes through a central aperture 26 in a fixed mould plate 9 for centre moulding, but is slidable on rails 6a (not shown) and the chamber is vertically displaceable, so that the apparatus may be adapted for off-centre moulding using aperture 25. Specification 760,480 is referred to.
