Title: Improvements in or relating to the distillation of coal, shale, peat, wood, and other bituminous or organic materials, and apparatus therefor
IPC: C10B1/04
Filed: 1919-05-13
Abstract: Aliphatic and aromatic synthese occur during the destructive distillation of fuel by a process in which the charge is treated with flue gas in admixture with extraneous gas.  The gases used include air, steam, hydrogen, tar &c. vapours, coal gas, water gas, blast-furnace gas, oxides of carbon, and aliphatic and aromatic hydrocarbons such as acetylene, olefines, hydrobenzenes, naphthenes, and phenols.  The working temperature may range from 100 to 1500 DEG C., and the pressure from a partial vacuum of 14\yF Hg. to 100 atmospheres.  Ionization of the gases may be effected as described in Specification 131,105.  The production of benzol, toluol, and xylol is stated to be increased.  Ethylene at a temperature of 500-700 DEG C. decomposes and forms acetylene which polymerizes to aromatic hydrocarbons; ethane at 675 DEG  C. forms ethylene, and eventually carbon, hydrogen, and methane.  In carrying out the invention, the gas mixture is introduced through flues perforated along their entire length.  Specifications 136,880 and 143,602, [both in Class 55 (i), Coking &c.], also are referred to.

Title: Starter apparatus for internal combustion engines
IPC: F02N15/06
Filed: 1949-05-11
Abstract: 658,445. Turning-gear. GENERAL MOTORS CORPORATION. May 11, 1949, Nos. 12507, 12508 and 12509. Convention dates, May 20, 1948, May 20, 1948 and Oct. 28, 1948. [Class 7(v)] In starter apparatus for internal-combustion engines comprising an electric motor having a shaft 32, a screw shaft 41 supported by the motor shaft 32 and driven thereby, a pinion 100 supported by the motor shaft for axial movement into mesh with the gear 106 of the engine to be started, a nut 51 threadedly engaging the screw shaft 41, a sleeve 83 which is moved axially by the nut and has an axial lost motion connection with the pinion by virtue of a longitudinal spline, a spring 102 for transmitting motion from the sleeve 83 to the pinion 100 in a direction to move the pinion towards the gear 106 and a clutch spring 90, which may be enclosed by a barrel 92, having its end turns normally in frictional engagement with the nut and sleeve in response to a rotative movement of the nut 51 relative to the sleeve 83 in the engine starting direction of rotary movement of the pinion, two abutments are provided consisting of a washer 111 on the motor shaft 32 and the end surface of the pinion 100, which abutments are adapted to contact when the pinion is fully meshed with the engine gear 106 so that the screw and nut rotate together as a unit. In operation, the pinion 100 is advanced into mesh with gear 106 in which position the abutments engage, the nut 51 continuing to move rightwardly until the inner end of the pinion 100 contacts a flange 84 on sleeve 83. The nut and screw shaft then turn together and the spring 90 wraps itself around the nut 51 and sleeve 83 until it transmits sufficient torque to crank the engine. When the engine starts the pinion and nut assembly are thrown back to the rest position and the spring 90 slips to dissipate some of the energy of the rotating parts. If tooth abutment occurs the nut 51 continues to rotate until sufficient torque is transmitted through the spring 90 to partially rotate the pinion 100 to index it whereupon the spring 102 moves it into mesh with the flywheel. In a modification, a stop nut and washer are located on the outer end of the screw shaft, the nut and screw shaft rotating together when the nut abuts the stop washer, which action occurs before the abutment of the pinion and flange 34 as in the Fig. 1 embodiment. In a further modification, a centrifugally operated latch is located on the nut so that the pinion is not demeshed in the event of a false start.

Title: Improvements in and relating to methods and devices for the removal of liquids containing solid materials and possibly gases from high pressure chambers
IPC: F16K25/04
Filed: 1935-04-26
Abstract: 457,447. Valves. UHDE, F., 79, Adolf Hitler Allee, Dortmund, Germany. April 26, 1935, No. 12556. Convention date, April 26, 1934. [Class 135] For discharging liquids containing solid materials and possibly gases from high-pressure chambers, e.g. in coal hydrogenation processes, a conical valve d co-operating with a conical seating c is employed, the valve being continuously rotated at a speed such that the velocity at the part of the obturating surface of maximum diameter is greater than the linear speed of flow with which the liquid would travel if the body did not rotate. Erosion of the operative surfaces of the valve is thus reduced. The parts c, d may be replaceable and may be made of hard metal such as chrome-nickel, tungsten or that known under the Registered Trade Mark " Widia." Rotation of the valve d is effected by means of a driven pulley e on its spindle, a hand wheel f being provided for adjusting the distance of the valve from its seating. A number of such valves may be arranged in series so that the pressure drop in the liquid is carried out in stages.

Title: Improvements relating to cathode-ray storage tube systems
IPC: H01J31/12
Filed: 1950-05-19
Abstract: 673,502. Pulse storage circuits. STANDARD TELEPHONES & CABLES, Ltd. May 19, 1950 [May 26, 1949], No. 12579/50. Class 40 (vi). In a cathode-ray tube device for storing variable electrical information by scanning a storage mosaic, the stored information may be taken off by a further scanning process and the charge restored to its original stored condition by scanning the mosaic under the control of a portion of the derived information. The Figure shows a cathode-ray tube store in which signals to be stored are applied via switch 20 to the control electrode of a gun assembly 2 in a storage tube to amplitude modulate the electron beam and set up a storage pattern on mosaic 1. The beam is scanned by deflecting plates as shown at 16. The input signals are disconnected when the charge pattern on mosaic 1 is completed and the electron beam from gun 2 may be used as a " sampling " beam, the signal produced across load resistor 10 at any instant of the scan being proportional to the charge on the elemental area of mosaic 1 which is being scanned. A portion of this signal is used to modulate the beam current in a display cathode-ray tube 11 which is scanned in synchronism with the beam of gun 2 so that a pattern indicative of the charge pattern on mosaic 1 of the storage tube and thus of the stored information is produced on the fluorescent screen 13. A further portion of the signal across load resistor 10 is applied via an amplifier 14 and delay network 15 to modulate the electron beam of a second gun 3 in the storage tube. The delay of network 15 is adjusted so that the " sampling " and " restoring " action of the two beams are effectively in synchronism and the charge pattern on mosaic 1 is restored to its stored condition.

Title: Improvements in or relating to a method and apparatus for applying a uniform coatingof liquid to a continuous filament
IPC: B05C7/08
Filed: 1947-05-09
Abstract: 657,537. Coating wires. VALDENE, J. DE LA. May 9, 1947, No. 12599. Convention date, March 18. [Class 140] A coating liquid is applied to a filament, e.g. a wire, by first applying an excess of liquid to the filament and then removing the excess by tangential contact of the filament with a rotating cylindrical surface to which has been applied a limited amount of liquid by rapidly rotating the surface in contact with a thin layer of liquid confined between the rotating surface and a stationary concave surface. The excess of liquid is applied by a roller 35 grooved to receive several wires and the excess from each removed by a blotting roll 36 damped by contact with a film of liquid confined between the roller and a shield 62. A second blotting roll 37 and co-operating shield 63 may also be included. The applicator roll 35 rotates adjacent a shield 61, liquid being supplied to the space between the roll and the shield through a pipe 69. The three rolls and their co-operating shields are mounted within a liquid container 1, the shields extending across the full width thereof, liquid entering the spaces between rolls 36 and 37 and their co-operating shields through ports 66 and manifolds 67. Doctor knives or brushes 91, 92 and 93 cooperate with the rollers 35, 36 and 37, such that the liquid upon roller 35 is confined to its grooves, and upon rollers 36 and 37 to a thin film. Liquid from the container 1 is recirculated through a filter 75 and shield 61 which also carries a series of fingers 101 entering the grooves to facilitate the return of the coating liquid from the grooves to the space between the roll and shield 61. The rollers 36 and 37 rotate at a higher peripheral speed than the speed of the wires whereas the peripheral speed of the applicator roll is less but of the same order of magnitude. The rollers are geared together and may be constructed to facilitate removal.

Blowing; shearing; delivering molten metal.- In a bottle-blowing machine of the type in which the moulds are carried on rotating tables, the parison is formed and blown to its finished shape in the neck-down position during the whole operation. Fig. 1 shows the parison mould table and Fig. 2 the finishing-mould table, which is above the level of the former. The tables overlap slightly, so that the moulds come into axial alignment at the position 100 to facilitate transfer of the parison. The parison table rotates intermittently in a clockwise direction, the finishing- table in an anti-clockwise direction. A hand brake is used to arrest the tables without shock. The molten metal flows directly from a hole in the furnace into the parison mould 32, Fig. 8, and is drawn down into the neck cavity by suction applied through a pneumatically-operated nozzle 47, passages 60, 43, and slots 29. The charges are cut by pneumatically-operated shears. In moving to the next station, the nipple 39 is lowered by a cam 69. A cover 73, Fig. 9, is then brought down and the parison is partly blown by air admitted from a nozzle 67. At the transfer station, a suction head 101, Fig. 5, is lowered into contact with the parison in the mould 32 and lifts it axially into the finishing-mould 140, where it is blown by air admitted through a passage in a slide 138. The finished bottle is removed by an automatic deliverer 207, Fig. 2.

Abstract: 1,273,462. Deuteration of amines. ATOMIC ENERGY OF CANADA Ltd. 18 March, 1970 [8 April, 1969], No. 13022/70. Heading C2C. [Also in Division C1] A process of extracting deuterium from a gas stream also containing hydrogen and nitrogen e.g. ammonia synthesis gas stream, comprises using two upper cold towers C U1 , C U2  the gas stream only passing through cold tower C U1 , where it loses deuterium to an exchange liquid 2. The exchange liquid 2 is divided into two streams 2<SP>1</SP>, 211 which recombine beneath C U2  to pass through lower cold tower C L  and hot tower H and to respectively take and give deuterium from and to a hydrogen stream passing in path 3, 3b, 3a. Deuterium concentrated streams 2c, 3c are tapped off. Any nitrogen which passes into the exchange liquid in C U1 , is stripped in stripper 5 by countercurrently contacting with a stream of hydrogen 4 tapped from the main stream and which then flows to the synthesis gas. The hydrogen is replenished by stream 5. Alternatively the nitrogen may be removed by flashing or by using a different hydrogen source. The exchange liquid is an amine e.g. having up to five carbon atoms/molecule, water or any mixture thereof with ammonia and may contain a catalyst e.g. potassium amide. Amines specified are 1,2-diaminoethane and 1,2- and 1,3-diaminopropanes.
