Patent GB-767400-A (GB)
Title: Process for the manufacture of trialkylaluminium compounds
IPC: C07F5/06
Filed: 1953-05-12
Abstract: Aluminium trialkyls are prepared by reacting an alkyl halide in the absence of ether at a temperature between 30 DEG  and 170 DEG  C. with an aluminium-magnesium alloy containing from 57 to 65 per cent of magnesium.  The alloy may be used in a finely divided form, and a little iodine or alkylaluminium sesquibromide may be added with the alloy to catalyse the reaction.  It is preferred to use the alkyl halide in the undiluted state but the reaction may be carried out in an inert solvent, e.g. hydro-aromatic hydrocarbons.  The reaction products usually contain some halogen and it can be removed by further treatment with the finely powdered aluminium-magnesium alloy at a temperature of 150 DEG  to 170 DEG  C.  In the examples the alloy contains 60 per cent magnesium, and trimethyl-, triethyl- and tri-n-butyl-aluminium are prepared.

Abstract: 543,375. Cracking oils catalytic processes. STANDARD OIL CO. Aug. 30, 1940, No. 13652. Convention. date,. Sept. 13. 1939. [Classes 1 (i) and 32] [Also in Group IV] In processes for the endothermic catalytic conversion of hydrocarbons, e.g. cracking, reforming, dehydrogenation, desulphurization and aromatization, followed by the exothermic regeneration of the contaminated catalyst by treatment with oxidizing gases, of the kind in which the catalyst is passed in suspension through the catalytic and regeneration zones, these zones are arranged in heat exchange relationship so that the heat given off in the regeneration zone is utilized to supply heat to the conversion zone. Preferably the zones are arranged so that the hottest part of eash zone is opposite the coolest part of the other zone. Gas oil vaporized in coil 12 is mixed with catalyst from purging zone 35 suspended in inert gases supplied through line 38 and the suspension is passed through re-action conduit 16 enclosed in an insulated chamber 17. The products pass through line 18 to cyclone separator 19 from which vapours pass through line 26 to the usual fractionation and condensation plant. The separated catalyst is fed through purging chamber 22 in counter current to inert gases supplied through line 24 and is then passed through regeneration zone 28 arranged in the chamber 18 parallel to and in heat-exchange relationship with the conversion zone 16. Regeneration gases, e.g. mixtures of air and inert gases are supplied through lines 29. 30. The regenerated catalyst is separated from the regeneration gases in separator 32 and then purged with inert gases in tower 35 whereupon it is returned through valve 37 to the conversion re-action. Conversion temperatures of 800- 900‹F. and regeneration temperatures of 1050- 1150‹F. are specified: In the modification shown in Fig. 2 the re-acting materials are passed through a continuous looped passageway 41, 42, 43, 44 constituting the conversion (41) regeneration (43) and purging zones (42, 44) the zones 41. 43 being arranged in concurrent heat relationship.

The vitreous silica may be prepared by oxidation of SiCl 4  vapour in a hydrogen-free atmosphere, the dopant being entrained in the reaction mixture. Alternatively, the dopant gas may be passed through a silica tube, a dopant-free gas being maintained outside the tube. The core/cladding assembly may be drawn at 1900-2000‹ C. in an Ar or Ar/O 2  atmosphere.

Abstract: 667,973. Clutches; variable-speed gearing. MERCIER, R. M. May 24, 1949 [May 31, 1948; July 7, 1948; Nov. 18, 1948; Feb. 15, 1949], Nos. 13877/49, 13878/49, 13879/49 and 13880/49. Class 80 (ii). In a machine for coiling webs, sheets, threads or strips on a reel 33, Fig. 1, the reel mandrel 34 is' driven from a motor-driven shaft 42 through friction members 41, 40 and worm or helical gearing 37, 43. A pressure E, varying automatically in proportion to the radius of the coil, is applied to the end of the worm 37 by a bellcrank lever 46 carrying a weight 47 which is moved out along the lever as the coil radius increases by a roller 48 maintained against the surface of the coil by a counterweight 50, while an oppositely-acting reaction pressure D is exerted on the worm by the resisting torque, resulting in the members 40, 41 being pressed into contact by the difference between the two pressures E and O. The tension in the web being coiled is thus maintained constant, irrespective of the radius of the coil or of the coefficient of friction between the members 40, 41. By immobilising the shaft 42, the members 40, 41 act as a brake for maintaining constant tension during uncoiling of the web. Screw-operated means may be provided to adjust the lateral position of the fulcrum 44 of the lever 46 so as to vary the pressure E. The roller 48 may be separate from the weight 47 and arranged to move the latter by Bowden mechanism. In the arrangement shown in Fig. 6, the roller 48 is replaced by a pivoted cradle 73, 74, 75 carrying a light source 81 and a photo-electric cell 89, the arrangement being such that, as the light beam is intercepted by an increase in the radius of the coil, a relay 83 is operated to energise a motor 84 which causes the cradle to follow-up the increase in coil radius. An extension 76 of one arm 75 of the cradle effects movement of the weight 47 on the lever 46. In the arrangement shown in Fig. 7, the shaft 42 is driven from a motor through expanding-pulley variable-speed gearing 94, 96, 98 controlled by a lever 102 linked by a rod 104 to the weight 47, so that the slip between the friction members may be reduced.
