Title: A process for the preparation of ethylene
Inventor: GROENENDAAL WILLEM
IPC: B01J23/00
Filed: 1967-07-31
Abstract: 1,148,967. Ethylene. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. 31 July, 1967 [2 Aug., 1966], No. 35039/67. Heading C5E. Ethylene is produced by a two-stage cracking process in which a hydrocarbon oil boiling below 250‹ C., e.g. straight-run naphtha, is first catalytically hydrocracked, the hydrocarbon products being then separated and thermally cracked in the presence of steam to yield ethylene which is separated. Suitable conditions for the first stage are 200-500‹ C., 10-500 atm. pressure, a space velocity of 0À1-10 vol/vol/hour and a hydrogen-oil volume ratio of 150-5000:1. The catalyst may comprise a metal of Group IB, VI B  or VIII of the Mendeleef Periodic Table and/or an oxide and/or sulphide thereof supported on a solid acidic refractory carrier, and preferably containing chlorine and/or fluorine. A preferred catalyst is Pd or Pt on a molecular sieve, e.g. mordenite, treated with a hydrohalic acid. The products from the first stage may be water-washed to remove impurities such as H 2 S and ammonium compounds, and then distilled to separate a hydrocarbon mixture, mainly C 2-5  alkanes, which is passed to the second stage. Suitable conditions for the second stage are: 600-900‹ C., 1-2 atm. pressure, 0À2-5 seconds residence time and 0À1-10 kg. steam/kg. hydrocarbons. The product of the second stage is water-cooled, separated and dried, freed from hydrogen which is recycled, and then fractionated to separate first methane, then product ethylene, then ethane which is recycled to the second cracking stage, and finally higher hydrocarbons. The two-stage process increases ethylene yield over a conventional one-stage thermal cracking.

Filed: 1961-09-19
Abstract: 1,019,992. Traversing device. BUCKLEY, MYERS & TAYLOR Ltd. Oct. 1, 1962 [Sept. 29,1961], No. 35105/61. Heading DlJ. [Also in Division F1] A hydraulically actuated traversing mechanism for a bobbin winding machine comprises a carriage 13 slidable on guide rods 10 and 11 between adjustable stops 12 on the guide rod 11. Secured to the carriage 13 are two cylinders 17, 21; the cylinder 17 being slidable on a fixed hollow piston rod 16 leading to an end housing 6, and the cylinder 21 being slidable on a fixed hollow piston rod 23 leading to a second end housing 7. The guide rod 10 is hollow so that pressurized fluid may be conveyed from the housing 6 to the piston rod 23 via the end housing 7. In operation a change-over valve in the housing 6 causes pressurized fluid to be applied to the 'hollow guide rod 10, and hence to the hollow piston 23, to cause the cylinder 21 to move to the right. This moves the carriage 13 to the right until it strikes the right-hand stop 12 to give an impulse to the guide rod 11. The impulse applied to the guide rod 11 operates the change-over valve in the housing 6 to cause the pressurized fluid to be applied to the hollow piston 16 whereupon the cylinder 17 moves to the left. This moves the carriage 13 to the left until it strikes the left-hand stop 12 to give a further impulse to the guide rod 11 to cause the change-over valve in the housing 6 to revert to its initial setting.

Title: Improvements in clutches
IPC: F16D7/02
Filed: 1922-12-28
Abstract: 191,716. Broussouse, F. L. Jan. 11, 1922, [Convention date]. Clutches, friction; securing pulleys on shafts.-In clutches for permitting propressive loading of motors, particularly squirrel-cage induction motors, a pulley hub 1, secured to the motor shaft, is connected to the rim 8 by Weston-type discs 5, 6, which are splined respectively to ribs 2 of the hub and ribs 7 of the rim, and are pressed by springs 10. The pulley contains an annular chamber 12 adapted to be filled with oil through a plugged orifice 13 up to the level MN, this oil penetrating between the discs by capillary action when the shaft is stationary. The driving-discs 5 have radial grooves 11, Fig. 3, on both surfaces, so that the oil is gradually expelled by centrifugal force and forms an annular mass running clear of the discs. As the coefficient of friction may thus rise from 0.01 to 0.15-0.20, slip ultimately ceases.
