Title: A process for producing caking coal or coke from non-caking coal
IPC: C10L9/00
Filed: 1939-04-21
Abstract: 533,006. Coking processes. COLLIER, C. S. J. (Fox, C. S.). April 21, 1939, No. 12028. [Class 55 (i)] Non-caking coal is converted to coal of caking quality by treating coal slack containing at least 5 per cent. moisture and less than 5 per cent. compounds soluble in pyridine with coke oven gases not below 500‹C, in the absence of air or oxygen, the coal absorbing hydrocarbons, and reacting with hydrogen present in the coke oven gases. The coal of caking quality may then be used for the production of coke, and the gases obtained used in the conversion process. The coke oven gases should be heated to at least 500‹C. and preferably about 900‹C. The coal slack, previously washed, is fed by a conveyer 20 on to a draining screen 22 through which the moisture passes to a return conduit 23. By lowering chain 6, an inlet door 17 drops, and the damp slack falls into the top compartment 1 of a chamber C, and, owing to the lowering of bells B', B<SP>2</SP>, B<SP>4</SP>, fills compartments 2, 3 and 4, the bell B<SP>4</SP> preventing the charge from passing downwards. Hot unwashed coke oven gases at not less than 500‹C. are introduced through inlets 10<SP>2</SP>, 10<SP>3</SP> into contact with the charge. Bell chain 6 is then raised, whereby compartments .1, 2 and 5 are closed by bells B<SP>1</SP>, B<SP>2</SP>, and B<SP>5</SP>, and compartments 3 and 4 are opened by raising-bell B<SP>4</SP>, allowing the treated slack to pass into the lower compartment 5. The gases from compartments 3, 4 and 5 escape through outlet 10<SP>5</SP>. When the chain is next lowered the hot coal slack falls through opening 5b into hopper 11, and entrained gases escape through vents 15a, 15b, simultaneously with the entry of a fresh charge through inlet 16. A counter-current of hot gases could, if desired, be used. Steam condensing in the dome 8 passes out through a steam trap 24 and drain 25. The apparatus may be used in conjunction with a coke oven which supplies the reacting gases and uses the coke obtained.

Title: Improvements relating to selective conveyors
IPC: B65G47/48
Filed: 1945-05-14
Abstract: 591,576. Selective conveyers. SOVEX, Ltd., CADMAN, H. W., ROOKE, S: W., and PELLY, N. H. May 14, 1945, Nos. 12038/45 and 5777/46. [Class 78(i)] In a chain conveyer of the type wherein trays carried by the chain are fitted with triggers which control discharge from the tray, the trays are mounted above or upon the chain. Tray 4, Figs. 1 and 2, pivoted at 5 to bracket 6 resting upon slipper 2 of chain 1, is held in position by spring-loaded pawl 7. Parcel is placed on tray for delivery to point 15 (say) and key 15 on front edge of tray is depressed, so setting trigger 13. At discharge point 15 are three trip levers, 16, 17, 21 coupled as shown. Neb 12 initiates movement by striking lever 16 which swings up lever 21 so disposed that it contacts trigger 13, and the double movement is sufficient to cause lever 17 to oscillate and strike pawl 1 and release tray. Latter then pivots so that roller 10 runs along ramp 11 till finally tray tips again and discharges parcel. Parcel discharges into chute 28, Fig. 2, and lip 14 of key 15 strikes spring-cushioned lip 29 of chute and key moves back into normal unset position. The levers return under action of springs to the ready position. In the second form of Figs. 4 and 5, spring 39 biasses the tray pivoted at 5 against the adjustable stop 41 and rod 33 against upper edge of slot 38. At delivery point are the trips 16, 17, 21, mounted upon rod 41 and, as the preset tray moves past, neb 12 engages lever 16 to partwise throw over lever system so that depressed trigger 131 strikes lever 21 which is knuckle-jointed at 42 to prevent damage if jammed, thus completing movement of lever 17 which jerks up tail 40 of rod 33. Latter rod pivots at 34 and depresses roller 35 to engage ramp 361 whilst at the same time urging the tray by means of spring 39 over clockwise ready to tip. Finally, depression of roller 35 under the influence of the ramp causes tipping. To set discharge point out of action rod 41, Fig. 5, may be moved to the right by finger 44 actuated by toggle-action spring 45, so that the three trip-levers are held down against contact with the moving tray. The tray may be mounted on plate 51, Fig. 7, upon brackets 52 secured to a " universal "- jointed biplanar-link chain which pivots horizontally about bolt 48 and vertically about bolt 49 due to small link elements 50. Chain runs on rollers 53, which work in flanges 56, Fig. 4. At any delivery station a warning light may be actuated by the full travel of the lever arms or a previous station may give a light warning of the discharge at a subsequent station. Specification 460,920 is referred to.

Title: Decoding and printing system
IPC: G06K17/00
Filed: 1959-04-10
Abstract: 865,511. Statistical apparatus. STANDARD TELEPHONES & CABLES Ltd. April 10, 1959 [April 16, 1958], No. 12216/59. Drawings to Specification. Class 106 (1). [Also in Group XVI] A system for decoding and printing information recorded on a magnetic record is characterized in that said magnetic record appears on individual documents or on document carriers (a piece of magnetic tape affixed to a jacket enclosing a cheque), that said system includes first means for reading said recorded information, second means for transmitting the read information to a storage device, third means for transmitting the stored information to a recoding circuit, and fourth means, associated with said recoding circuit, for transmitting the recoded information to a printer which is able to print this information. In the system described data from a cheque is doubly recorded, in true and complement form (in the Aiken code) and the jacketed cheque is passed to a sensing station. The jacket is then examined photoelectrically to ensure that it contains a cheque and the data is read, by ahead which is moved over the stationary jacket, from the strip of tape. The data then passes, parallel by binary bit and serial by decimal digit, to a shift register, each stage comprising four coldcathode gas discharge tubes. The data enters the shift register in complementary form first displacing, as it enters, the data read from the previous cheque-jacket and as this occurs a comparison is made to detect a change in the account number. The complementary form of the data is followed and displaced by the normal form (the shift register being long enough to store the data only once) and a further comparison-of the entering normal data and the displaced complementary data-is effected as a check. If no error is detected the data then passes via a relay recoding circuit having a oneout-of-ten output for each decimal digit to a totalizer and printer of known type. The system described can operate in two different modes. In an " automatic feed " mode cheques are fed continuously until the account number changes whereupon the machine stops and only restarts when the operator depresses a " print " key when it prints the total amount relating to the particular account being analysed. In a " single feed " mode, which is only used when there is one cheque only for each account, no totals have to be printed and the machine proceeds automatically printing the amount and account number for each cheque read. After the jacketed cheques have been read they pass to a known unjacketing machine. Specifications 663,574 and 861,013 are referred to.

Abstract: 1376163 Making battery plate grids JOSEPH LUCAS (INDUSTRIES) Ltd 14 April 1972 [30 April 1971] 12328/71 Heading B3A [Also in Division H1] A method of making a battery plate grid 11  comprises blanking a strip of grid material to form a preformed grid having a rectangular framework of substantially the same dimensions as that of the finished grid and a plurality of strands 14 defining a lattice structure having dimensions in a direction perpendicular to a plane parallel with the rectangle defined by the framework less than those of the lattice structure in the finished grid, and displacing the strands in a direction perpendicular to said plane to increase the lattice dimensions in said plane to those required in the finished grid. The preformed grid is blanked from a strip of dispersion strengthened lead, which may be pre-shaped to define ribs 12 and/or one pair of parallel frame members. The grid material may alternatively be a lead alloy, e.g.lead-antimony, lead-calcium. The ribs and strands may be coined during the displacing operation to reshape them into a rhomboidal or triangular cross-section, Figs. 4 and 5 (not shown). These sections provide keying regions for the active material of the battery plate. The displacement of the strands allows the grid to retain a larger volume of active material than a flat grid of the same weight.

Inventor: MACONOCHIE HARRY
Filed: 1917-09-01
Abstract: 118,665. Maconochie, H., and Ros, D. de. Sept. 1, 1917. Zinc oxide is produced by blowing heated air or oxygen on to or into melted zinc or a mixture containing zinc, the supply of heat being discontinued when the reaction has started. The process may be combined with the extraction of zinc from zinc-sulphide ore by means of iron, the zinc sulphide being mixed with scrap iron and melted, and the heated air being blown upon or into the molten mass. Additional quantities of zinc or zinc ore and iron are added gradually to avoid lowering the temperature, and may be preheated. The heating of the reaction mass may be effected by an oil burner or by an electric resistance. Additional air may be supplied to the oxide fume to complete the oxidation. The surplus heat of reaction is used to heat, in an adjacent chamber adapted for the purpose, the air required for the reaction.
