Title: Improvements in the cooling of coke or like material and utilising the sensible heatthereof
IPC: C10B39/02
Filed: 1927-10-14
Abstract: 280,514. Frankfurter Gasges., Tillmetz, F. P., and Schumacher, E. Nov. 11, 1926, [Convention date]. Cooling discharged materials.-In coke-cooling apparatus, of the kind in which a stream, of inert gas is circulated through the coke and a boiler plant, the cooling process is carried out in two or more separate stages for the production of high pressure steam, low pressure steam, and/or hot water. As shown, incandescent, coke is fed to a hopper 1 and passes to a stepped grate 2 through which inert gas is forced by a blower 6, the gas, after absorbing heat from the coke, passing over the tubes 4 of a high pressure boiler 5 and returning to the blower through a conduit 8. A part 10 of the boiler 5 is located in a separate compartment heated by gas burners 11 so that the boiler may be used when hot coke is not available. From the grate 2, the partly cooled coke passes to a chain grate 12 where it is again exposed to inert gas which is supplied by a blower 16 and, after passing through the coke, flows over a feedwater heater 18 for the boiler 5 and re-enters the blower through a pipe 19. The coke finally passes into a bunker 20 where it is quenched by water from a nozzle 26 or low pressure steam supplied through a pipe 27. The bunker 20 is provided at the upper end with an outlet flue 22 in which are arranged dampers 23, 24, the latter being interconnected by links with a discharge valve 21 at the bottom of the bunker and the former with a gas-tight cover 3 for the hopper 1, the arrangement in both cases being such that when one valve is open, the other is closed. The steam generated in the quenching bunker 20 seals the latter against entry of air and is itself prevented from entering the preceding cooling stages by a pressure maintained therein by supplying flue gases to the blowers 6, 16. A door 30, for the removal of dust, is provided below the grate 12. The water heater 18 may be replaced by a low pressure boiler supplying feedwater to the boiler 5 or there may be interposed, between the two cooling stages described, an additional stage for the generation of low pressure steam. A modification is described in which the chain grate 12 is replaced by a second stepped grate at the lower end of which is a rotary drum for feeding coke into the bunker 20.

Title: Improvements in or relating to auxiliary gearbox driving arrangements particularly for motor vehicles
IPC: F16H3/32
Filed: 1939-10-06
Abstract: 534,292. Change-speed gear. THORNYCROFT & CO., Ltd.. J. I., and BURTON, C. E. Oct. 6, 1939. No. 27348. [Class 80 (ii)] [Also in Group XXXI] In a motor vehicle having an auxiliary twospeed gear-box 3 through which two shafts or axles 1, 2 can be driven, the drive on one gear ratio being to one shaft 2 only, the drive on the other gear ratio is transmitted first to one of the two shafts and then to the other without disengaging the drive to the first shaft. In the construction shown in Fig. 1 the lay-shaft 5 of the auxiliary gear is driven from the main gear-box (not shown) through a shaft 6 and gear 6a. The shaft 2 carries a double sliding gear 4a, 4b splined thereon, and when this gear is slid to the right from the neutral position shown the gear 4b engages the gear 5b and the shaft 2 is driven at the high-speed ratio. When the double gear is slid to the left the gear 4a engages a wide gear 5a and the shaft 2 is driven at a low-speed ratio ; further movement of the double gear to the left causes dogs 4c to engage dogs 1a on the shaft 1 and drive this shaft without the drive to the shaft 2 being disengaged. In a modification a single sliding gear is used on the shaft 2 and an additional gear loose on this shaft is always in mesh with the gear 5b.

Title: Apparatus for drawing sheet glass
IPC: C03B15/18
Filed: 1928-09-24
Abstract: 311,171. Haddan, P., (Virginia Plate Glass Corporation). Sept. 24, 1928. Drawing.-Apparatus for drawing sheet glass comprises an enclosed drawing-chamber arranged vertically above a crucible chamber and separated from it by a watercooled shield, and means are provided for controlling the temperature of the sheet at its point of formation, and for transferring the sheet to the leer without removing it from the drawing-chamber. The crucible chamber 20, Fig. 1, is heated by burners 22 and receives a pot 21 containing the molten glass. The chamber is covered by a watercooled shield 23 having an elongated opening or slot through which the glass sheet is drawn upwards by means of a bait 26. The pot 21 is mounted on a wheeled truck which can be raised or lowered by a screw jack 25 to adjust the distance between the top of the pot and the shield 23. The hot gases from the burners 22 pass upwards around the glass sheet through the slot in the shield 23, and by adjusting the pot in relation to the shield, the temperature can be regulated so as to maintain the proper viscosity of the glass at the point of formation of the sheet. The pot may be replaced by a stationary pot which is continuously supplied with molten glass by an adjacent melting-furnace. A fireclay thimble 74, Fig. 1<a>, fitted in the opening in the shield 23, varies the annular space between the top of the pot and the shield. Thimbles of different lengths are used according to the thickness of the glass to be drawn. The drawing-chamber A in which the bait 26 works is arranged over the shield 23 and is open on one side to a take-down chamber 27. The bait may be raised and lowered by mechanism arranged on the top 28 of the chamber A. It consists of two halves pivoted on a rod 67, and they are locked when closed by means of a latch 68 which is pivoted on the rod 67 and is swung down into a notch formed on one of the bait sections. A watercooled shield 29 travels up and down with the bait. A cutting- device, consists of blades operated by pneumatic cylinders 38 and mounted on the shield 23, is used to separate the sheet from the glass in the pot at the conclusion of a draw. The take-down chamber 27 extends between the drawing-chamber and a leer 32 which is heated by gas burners 33 that project flames into checker work 34. Trays 39 running along rails 42 carry the glass sheet through the leer. The take-down mechanism consists of a short section 42<1> of the leer track pivotally mounted on a wheeled truck 44<1> which can be moved to and fro by a pneumatic cylinder 46. A pair of grooved cam rails 52 engages rollers fixed to the truck 44<1>, and when the cylinder 46 moves the truck into the drawing-chamber, the cam rails turn it into the vertical position, as shown in dotted lines. A tray 39 supported on the truck is held in position by a hook and pin, and when vertical it receives a glass sheet which has been cut off by the shears. The truck is then moved back into the chamber 27 and the tray 39 with the glass sheet is moved into the leer.

Abstract: 519,542. Hydraulic control apparatus. OLAER PATENT CO. Sept. 22, 1938, No. 27624. Convention date, Sept. 27, 1937. [Class 69 (ii)] Hydraulic control apparatus comprises a liquid pump, one or more accumulators, a distributor, and conduits connecting these parts and the parts to be controlled, a valve member disposed in the conduit between the accumulator and the distributor, an auxiliary conduit between the valve member and the accumulator, an elastic reaction element acting on said valve element and cutting off the accumulator as soon as its pressure falls below a predetermined value, said auxiliary conduit being adapted to cause the liquid to act upon the valve member for reopening the accumulator after its pressure has increased. The delivery pipe 5 from the pump 1 divides into two branches passing to the accumulator 9 and the distributor 19a having non-return valves 8, 19 respectively. Situated in the connection 17 between the accumulator and the distributor is a slide-valve 15 loaded at one end by a spring and subjected at the other end to the accumulator pressure through a conduit 13 so that it cuts off the accumulator from the distributor if the accumulator pressure drops below a certain value. The distributor is in the form of a piston valve 20 operated by a hand-lever 22, and as shown is adapted for supplying pressure liquid to a jack operating the landing gear of an aeroplane. For raising the gear, pressure liquid is supplied directly from the pump 1 through a conduit 23 to one end of the jack cylinder 29 and exhausted from the other end through conduits 28, 25, 27. In the opposite position of the valve 20, as shown in full and dotted lines, pressure liquid is supplied to the other end of the jack cylinder from both the pump and the accumulator or from the accumulator only through conduits 24, 28, and the liquid is exhausted from the cylinder through the con-. duits 23, 27 and a passage 26 through the valve 20. The accumulator 9 may have an air cushion 10 which can be replenished through a valve 12 or automatically through a non-return valve. Further, two or more accumulators may be used in parallel for operating different devices such as lifting wings, rudder, or wing flaps of an aeroplane. A device 6 described in detail with reference to Fig. 2 (not shown) is inserted in the delivery conduit 5 of the pumps so as to connect the conduit 5 to discharge if an excessive pressure is built up and to maintain such connection until the pressure in the working conduits falls below a predetermined value. Specification 519,429 is referred to.

Abstract: 1379962 Tamperproof closures AUTOMATIC LIQUID PACKAGING Inc 14 June 1972 [26 Oct 1971] 27811/72 Heading B8T The end of an integrally sealed thermoplastic closure is severed from the container in unscrewing or screwing a cap or ring, threaded on the container neck, so that the contents of the container may be dispensed. The opened container may be resealed using the cap or ring together with the severed end which is retained within it. In Fig. 5 a ring 10 has coarse thread 13 in its sidewall and a fine thread 16 on an inner depending wall 25 provided with a cutting edge 27. The neck 22 of the container 20 has a threaded portion 23 integral with a narrower threaded portion 24 and terminates in a sealed conical tip 28. The ring 10 is screwed on the container, threads 13, 16 engaging threaded portions 23, 24, respectively. As the ring is further screwed down, the cutting edge 27 cuts through the annular top wall of the neck 21 and this wall is bent over and forced into the space 19 between the wall 25 and the sidewall of the ring to form a seal. As the ring is unscrewed the tip 28 is removed with it, being held by the thread 16, thereby providing a re-usable closure. The container may have an integral sealing cap 48, Fig. 8, joined by a neck 49 to a threaded portion 47. As the ring 40 is screwed on, the shoulder 44 snaps over the cap 48, but when the ring is unscrewed the cap 48 is severed from the container and retained within the ring so that the cap 48 and ring can together be used to reseal the container. An annular, metal or rigid plastics cutting blade, Fig. 9 (not shown), may be forcefitted into an annular groove in the side wall of the cap to sever and retain the cap 48. In Fig. 11 a ring 65 has a coarse thread 69 and a fine thread 67, and the container has correspondingly threaded portions 60, 58, respectively, separated by a reduced neck 62. The ring is initially screwed on until the fine thread 67 and threaded portion 58 just engage. The container is opened by further screwing on the ring until the strain imposed on the neck 62 by the differential screwing rates of the fine and coarse threads severs it. The ring together with the portion 68 can be unscrewed and used to reseal the container. The inner wall of a cap (70) may have a cutting blade (73), Fig. 12 (not shown), positioned so that, after the cap has been screwed down and the blade (73) has cut through the annular top wall of a threaded portion (31) of the neck, the blade retains the severed end (38) within the cap as the cap is unscrewed.

Title: An improved process for producing high-grade motor fuels from heavier carbonaceous material
IPC: C10G65/12
Filed: 1930-09-18
Abstract: In the destructive hydrogenation of heavy petroleum oils, a portion of the oil undergoing decomposition is removed from the reaction zone and is treated to reduce its heavy asphaltic content, the purified oil being then returned to the reaction zone for further decomposition.  The asphaltic content is reduced by a treatment with hydrogen in a second reaction zone at lower temperature.  Crude oil is forced by a pump 26 through a heat exchanger 17 and pipe 28 to a heating coil 1 where mixed with hydrogen from a pipe 13 it is heated to 900 DEG  F. and then passed into a pressure reaction drum 4, maintained at a pressure of about 200 atmospheres.  Part of the oil is continuously withdrawn through a pipe 5 to a second reaction drum where the asphaltic content is reduced by treatment with hydrogen admitted through a pipe 12 at the same pressure but at a temperature about 800 DEG  F. The purified oil is returned through a pipe 8 to the coil 1. Vapours produced in the drums 3, 6 are withdrawn through a line 16 and condensed by passage through heat exchangers <PICT:0361046/III/1> 17, 18 and a cooler 19 and the condensate is separated in a separator 20 from gaseous products and excess hydrogen which is returned after purification to the coil 1 after passage through the heat exchanger 18.  Part of the crude oil may be circulated direct to the drum 6 through a pipe 29.  The drums 3, 6 may be packed with catalysts, e.g. oxides, sulphides, &c. of molybdenum, chromium, and other heavy metals with or without other metal oxides, e.g. those of zinc, aluminium or rare earths. Alternatively the catalysts may be suspended in the oil in a finely ground condition in an amount about 20 per cent by volume of the oil. The purification drum 6 may serve several primary reaction drums 3. Specifications 336,610 and 337,671, [both in Class 32, Distilling &c.], are referred to.
