Title: Improvements in or relating to the gasification of solid carbonaceous materials
IPC: C10J3/46
Filed: 1949-06-30
Abstract: 683,027. Distilling and gasifying carbonaceous solid material. HYDROCARBON RESEARCH, Inc. June 30, 1949 [July 20, 1948], No. 17326/49. Class 55 (i). A process of carbonising and gasifying a carbonaceous feed material with volatile constituents, e.g. coal, lignite or oil shale comprises mixing particles of this feed material with particles of carbonised material free from volatile constituents and withdrawing from a carbonisation zone, passing this mixture directly into the lower part of a fluidised bed of carbonaceous particles in a carbonisation zone 11 in which volatile constituents are distilled by the addition of a hot gas from a gasification zone acting as the fluidising medium, discharging the resulting gases at 25 and withdrawing the carbonised material through a pipe 17 and passing it to a gasification zone 12 to which steam and oxygen are supplied by pipes 18, 21, the hot effluent gas passing up a pipe 13 to heat and fluidise the mixture in the carbonisation zone 11, the residual solid being discharged through a pipe 23. Fine coal particles are fed from a container 7 held under pressure with inert gas by a pipe 8 through a conveyer 9 into the pipe 13 through which the hot gases at 2000‹F. rise from the gasifying zone 12 and char from the carbonising zone is fed by a pipe 14 at lower point to the pipe 13, so that a fluidised mixture is carried into the carbonising zone 11. A high class char may be drawn off the pipe 17 through a pipe 19 and a low class char is drawn off the gasifier at 23. A centrifugal separator 24 frees the product gas from dust. The gasifier is under a pressure of 350 lbs. per sq. in. and some solid may pass therefrom through pipe 13 to the carboniser. In Fig. 2 a portion of the effluent gas from the gasifier 32 is drawn off separately through a pipe 47, is passed through a dust separator 48 and is cooled to below 1500<SP>o</SP>F. by water from a pipe 50 to prevent reaction between carbon monoxide and water vapour before rising to meet the product gas at 39 from the carboniser 31. Carbonised material entrained with the gases from the carboniser passing to the outlet 37 is separated at 38, and the char is returned through a pipe 43 in part to the gasifier 32 and in part through pipe 42 to the carboniser. The mixture fed to the carboniser preferably comprises 5 parts of char to one of coal. The carboniser is cooled by water pipes 36 forming a steam generator. Char direct from the carboniser, which is maintained at 900-1300‹F., may be fed through the pipe 44 to the mixing pipe 33. Residual char from the gasifier, which is maintained at 1600-2000‹F. is removed through a pipe 52 for use as fuel or passes through pipe 53 into a gas generator 54, e.g. where it is burnt with oxygen from the pipe 56, the product gas passing off at 57 and ash being removed at 58.

Abstract: 993,045. Jointing. DUNLOP RUBBER CO. Ltd. April 26, 1962 [May 13, 1961], No. 17502/61. Heading B3V. A method of bonding a synthetic rubber composition to a metal surface, e.g. in the manufacture of metal tyre cords, instrument mountings, engine mountings and synthetic rubber metal springs, comprises vulcanising while in contact with the metal surface a vulcanizable synthetic rubber composition containing a minor proportion of a cobalt salt sufficient to provide a metallic cobalt content of from 0.09% to 1.5% by weight based on the synthetic rubber. The synthetic rubber composition includes butyl rubber, butadienestyrene copolymers which may be oil-extended, cis - polybutadienes, hydrogenated polybutadienes and butadiene-acrylonitrile copolymers. The cobalt salt is an organic salt including cobalt linoleate, naphthenate, stearate, oleate, acetate and resinate. The metal surface includes mild steel, tungsten steel, zinc and brass. Other metal surfaces may be coated with e.g. brass or zinc. When bonding butadiene-styrene copolymers to brass the cobalt metal content of the copolymers is from 0À1% to 1À2%, when bonding to zinc the cobalt metal content is from 0.2% to 1.2% and when bonding any of the polymers to mild steel the cobalt metal content is from 0.1% to 0À6%. Several examples of synthetic rubber compositions are given in the Specification.

Title: Improvements in and relating to devices for purchasing returned containers, in particular bottles
IPC: G07F7/06
Filed: 1956-06-07
Abstract: 791,049. Vending apparatus. WIEGANDT, K., and WIEGANDT, W. June 7, 1956 '[July 23, 1955], No. 17589/56. Class 27 A device for accepting empty containers, such as bottles F, and refunding the charge made for them is fitted at the top of the insulated cabinet 6 of a vending machine and is provided with means for testing the shape of the body and mouth of the container to ensure that only sound, correctlyshaped containers are accepted. The bottle to be returned is inserted past a hinged flap 10 into a member 4 which has one or more chambers 5 and is mounted on a rotatable shaft 3 connected by gearing 6 to a shaft 7 which can be driven through a clutch 8 from a knob 9 on the outside of the machine. The chambers 5 are sloped so that any contents remaining in the bottle rest at the bottom and thus tilt the other way as the member 4 rotates and so drain the bottle into a container; alternatively, a separate tilting device may act on the bottles. Three feelers 12 engage the body of the bottle in the chamber 5 and set the position of locking plates 14 co-operating with a lock disc 16 on the shaft 3. If any of the feelers engage an oversize portion of the bottle, a surface 15 is moved to block a stop 17 on the disc 16 or, if an undersize portion is detected; a surface 15<SP>1</SP> is moved to block an adjacent stop 17. The mouth of the bottle enters between a number of spring-loaded jaws 22 pivoted on a support 21 and, if the bead on the mouth is not chipped, all the jaws are opened to clear the head 20 of a support bolt 19 and allow the support to be pushed back by springs 29 out of the way of the member 4. With the locking disc 16 free and the support 21 retracted, the member 4 may be rotated through 120 degrees by the knob 9 to deliver the bottle to a shoot 2 and thence to. a conveyer K by means of which the bottles are conveyed to a lower compartment of the machine; bottles of non-circular section are constrained in their movement down the shoot by paddles 45 or guide rails. A drive pin on the shaft 7 engages a driver on a disc 32 rotatable on the shaft and the disc, after it disengages from a pawl 35, topples over so that an arm 34 closes a switch 51 in the circuit of an electromagnet 53 for returning the support 21 to locking position. There is, however, no current supply to the switch 51 until the bottle, in moving to the shoot 2, closes a switch 52 that also connects the current supply to the electromagnet of a money-refunding device. To prevent operation of the device by the insertion of the hand or a template or wire, the flap 10, if open, moves a lever 41 so that the feelers 12 are held in a position in which the locking plates 14 block the disc 16. The rotatable member 4 may be replaced by an endless conveyer band.

Abstract: 380,811. Telephone instruments. WESTERN ELECTRIC CO., Ltd., Bush House, Aldwych, London, and ELECTRICAL RESEARCH PRODUCTS, Inc., 195, Broadway, New York, U.S.A.-(Bell Telephone Laboratories, Inc. ; 463, West Street, New York, U.S.A.) June 18, 1931, No. 17717. Addition to 333,578, [Class 40 (iv), Telephones &c.]. [Class 40 (iv).] An electrodynamic device as described and claimed in the parent Specification is modified by providing that the apertured damping plate 23 arranged under the diaphragm 19 is spaced from the central magnet pole 14 so as to form an additional air passage which is continuous with the magnetic air gap 22a, and which is sealed from the air in the casing of the device by a disc 27 of rubber or the like. With this construction, the position of the coil 22 carried by the diaphragm may be viewed during assembly, for example by means of a microscope, from the back of the magnet, before the sealing device 27 is placed in position, so that the coil can be accurately centralized. The electrodynamic transmitter shown comprises a permanent magnet, preferably of an alloy consisting of 35 per cent cobalt and 65 per cent iron, having a central pole 10 and four equally spaced legs 11. Cast inserts 12, 13 of soft iron are provided in the legs and in the central pole, and in assembling the parts a domeshaped polepiece 14 is first secured to the pole 10 by a bolt 15 threaded into the insert 12. An annular polepiece 16 is then placed upon the upturned legs 11, with an accurately machined cylindrical gauge interposed between the polepieces 14, 16. Holes are drilled through the polepiece 16 and into the inserts 13, and after the holes in the member 16 have been slightly enlarged, dowel pins 18 are slipped through these holes and forced into the drilled inserts, the gauge being then removed. The diaphragm 19, preferably made of an aluminium alloy, is located in position by the dowel pins passing through oversized apertures in the diaphragm and in paper &c. washers 21 on both sides of it. The damping plate 23, formed with elongated slots 24, is attached by bolts 25 to the annular polepiece 16, together with a spacing member 26. After the position of the coil 22 carried by the diaphragm has been correctly adjusted in the magnetic air gap, the diaphragm is fixed in position by a clamping plate 29, to which the damping plate 23 is then held by bolts 30. The annular polepiece assembly is removed from the legs 11, and the sealing ring 27 and a guard ring 28 is fixed in position by the bolts 25. Finally, the assembly is again slipped into place over the dowel pins 18. The flat ribbons 31, Fig. 4, forming continuations of the coil 22, are protected by being passed out between the paper washers 21 to insulated terminals 32.
