Abstract: 1,156,317. Epicyclic change-speed gear. AUTO TRANSMISSIONS Ltd. 22 July, 1966 [24 Aug., 1965], No. 36423/65. Headings F2C, F2D and F2E. In a motor-vehicle three-element epicyclic overdrive, or underdrive, gear unit in which a clutch-brake member 29, 30 is loaded by springs 49 to clutch a freely mounted axially movable sun 26 to an output ring-gear 15 for direct lockup drive, and oppositely moved by a fluid pressure operated annular piston 42 to brake the sun 26 to a fixed casing 36 for drive at the planetary ratio, clutch engagement during overrun or reverse in direct drive ratio, and brake engagement during forward drive in overdrive ratio is variably augmented by the torque responsive thrust of helical teeth of the gearing or, in an alternative arrangement, by helical spline engagement between the sun 26 and the clutch-brake member 29. The clutch-brake member is a two-part unit comprising a clutchbrake cone 29, carried with aixal play on shouldered spacer studs 40 riveted to a brake cone 30, both cone members 29, 30 being splined, axially fast and free respectively, on the sun 26. Thus in overdrive, with the fluid pressure operated brake cone 30 engaged, the brake cone 29 is additionally independently engaged, through the axial play on the spindles 40, by the variable load of the torque responsive helical gear thrust. During direct lock-up forward drive, the clutchbrake member is loaded by the springs 46 to disengage both brake cone surfaces 37, 34 and engage the clutch cone surface 32 with the ring gear 15 to lock the sun 26 thereto but plays no part in the forward torque transmission which is directly through a one-way clutch 21, however, during reverse torque, e.g. overrun or reverse gear engagement, when the one-way clutch 21 becomes ineffective, the clutch 32 takes the drive and, in addition to the spring thrust the clutch engagement is increased by the variable load of the torque-responsive helical gear thrust which now acts in the opposite direction.

Abstract: 1,184,683. Boundary layer control. MINISTER OF TECHNOLOGY. 1 Aug., 1968 [10 Aug., 1967], No. 36856/67. Heading F2R. [Also in Division F1] The distribution between primary and dilution air entering a gas turbine engine flame tube 2 can be controlled by applying suction through pipes 19, 18 and passages 16, 17 to annular slots 14, 15 in a flow divider 9 to draw off the boundary layer flow passing through a gap 13 between the divider 9 and the flame tube 2. The airflow through gap 13 to the combustion zone is thus increased and the dilution flow to space 6 decreased. In a modification, (not shown), the boundary layer can be drawn off through holes (27) in a hollow ring (26) mounted on a modified flow divider (21, 22) within the flame tube. In other modifications suction can be applied through holes, meshes, porous media or other openings, e.g. in the surfaces of guide vanes at the combustion chamber inlet. Valves may control the suction automatically in response to pressure, temperature, density, speed or fuel flow.

Abstract: 1353087 Gas-phase polymerization process MITSUBISHI PETROCHEMICAL CO Ltd 6 Aug 1971 [8 Aug 1970] 37110/71 Heading C3P [Also in Division B1] Polymerization of α-olefins in the gas phase is carried out under the following conditions: (1) a reaction chamber in the form of a vertical cylinder is used and the reaction bed, comprising a particulate polymer and a catalyst, is caused to circulate in a vertical direction, principally by mechanical agitation (2) the ratio of the diameter to the height of the reaction bed is 1 : 0À5 to 1 : 3 (3) the monomer is supplied in the liquid state from a point above the reaction bed and vaporized within the reaction chamber (4) the heat of polymerization is removed principally by the vaporization of the monomer. The process is preferably carried out continuously using a Ziegler-type catalyst. The agitation of the reaction bed is preferably effected by a ribbon-type stirrer, 3, with an anchor-shaped portion, 2, at the bottom to carry the particles which descend at the centre of the vessel back to the walls. In the illustrated apparatus inlets N-2 are provided for catalyst or catalyst components, polymer is withdrawn at N-4 and monomer is introduced at N-1 and sprayed into the reaction chamber by device 4, which comprises a pair of perforated pipes. Normally the amount of monomer supplied to absorb the heat of reaction is greater than the amount actually polymerized, so the excess is withdrawn at N-3, cooled and condensed for recycling to N-1. The examples describe the polymerization of ethylene or propylene with a TiCl 3 /Et 3 Al or TiCl 3 /Et 2 AlCl catalyst by the method of the invention and also describe the effects of using circumferential agitation or of introducing the monomer directly into the reaction bed for comparison.

Abstract: 1391279 Cracking and reforming naphtha UNIVERSAL OIL PRODUCTS CO 10 Aug 1972 [11 Aug 1971] 37334/72 Heading C5E An aromatic fraction and an isobutane traction are obtained from naphtha by (a) reforming the naphtha under conditions to convert not less than 80% of the naphthenes but not more than 40% of the alkanes to aromatics, (b) separating aromatics from saturated hydrocarbons in the reformate, (c) cracking the saturated fraction with hydrogen over a specified catalyst, and (d) recovering isobutane from the cracked product. The catalyst for the hydrocracking comprises a noble metal of Group VIII or nickel on an alumina base, modified by subliming on to it a Friedel-Crafts halide. As shown, a hydrofined heavy naphtha (heptanes and upwards) in line 1 is reformed at 2 over a catalyst of platinum, rhenium and chlorine on an alumina carrier, and the product fractionated into hydrogen (recycled), a stream 3 of hydrocarbons up to propane, a butane stream 4, and a reformed naphtha 5. This is extracted with a solvent at 6, the extract 8 is separated from the solvent and goes to the gasoline pool 16. The raffinate from the extraction goes by line 9 to zone 11 where it is mixed with hydrogen and cracked over the specified catalyst. Light hydrocarbons (up to propane) are withdrawn by line 10, isobutane goes by line 12 to alkylatoin, pentanes and upwards are recycled to the extraction zone 6. A pentane-hexane fraction may be separated in the reforming zone (2) or in the extraction zone (6, as shown) and sent by line 7 to isomerization, or separated into normal and iso-fractions, of which the normal is sent to isomerization and the iso-directly to the pool 16. In the zone 17, pentanes and hexanes are isomerized over a catalyst of aluminium chloride and platinum on alumina, and the product goes by line 18 to the pool 16. In the zone 14, butanes from line 4 and isobutanes from line 14 are used to alkylate butenes from an outside source, over an HF catalyst. Unreacted isobutanes are recycled, and the product goes by line 15 to the pool 16.
