Title: A process for the production of olefine polymerisation catalysts, and the use of these catalysts in the polymerisation of olefines
IPC: C08F10/00
Filed: 1957-08-23
Abstract: Olefines are polymerized in the presence of a catalyst obtained by mixing together a titanium trihalide, a titanium tetrahalide, and an alkyl aluminium halide or an alkyl aluminium alkoxyl.  A mono-alkyl aluminium dihalide may be used in a quantity equivalent to the titanium tetrahalide, and the molar ratio between the titanium trihalide and the titanium tetrahalide may be from 0.1 : 1 to 100 : 1.  The titanium trihalide may be the brown precipitate obtained by reacting a titanium tetrahalide with a dialkyl aluminium monohalide, by treating a titanium tetrahalide with a silent electric discharge, by treating the vapour of a titanium tetrahalide with hydrogen in an ozone tube, or the violet titanium trihalide obtained by treating titanium tetrahalide with hydrogen.  The olefine may be ethylene, propylene, butene, hexene, butadiene, isoprene or styrene.  In examples, ethylene and propylene are polymerized using catalysts prepared from brown titanium trichloride, violet titanium trichloride, titanium tetrachloride, ethyl aluminium dichloride and diethyl aluminium chloride.ALSO:A polymerization catalyst is obtained by mixing together a titanium trihalide, a titanium tetrahalide, and an alkyl aluminium halide or an alkyl aluminium alkoxyl.

Title: Improvements in artificial filament manufacture and the like
IPC: D01D5/04
Filed: 1931-09-29
Abstract: <PICT:0390198/IV/1> <PICT:0390198/IV/2> <PICT:0390198/IV/3> <PICT:0390198/IV/4> In the production of artificial filaments, threads, yarns, straws, ribbons, and like extruded products by the evaporative process, the extruded products are caused to pass through a co-current of evaporative medium and additional evaporative medium is introduced into the co-current at a point intermediate of the ends of the spinning cell.  Alternatively, the co-current of evaporative medium and the additional evaporative medium are introduced at the same point in the cell and are caused to flow in opposite directions. The additional evaporative medium may be introduced symmetrically or on one side of the extruded products in the vicinity of the spinning jet, and in the latter case the current may be passed across the path of the extruded products to a draw-off pipe at the opposite side of the cell.  As shown in Fig. 1, filaments 14 are extruded downwardly from a jet 13 in a spinning cell 10 and pass through an opening 16, over a wick 29 supplied with softening agent, round stretching rollers 31, 32, and finally to a cap-spinning device.  Evaporative medium is introduced through a perforated annular pipe 17, part of it travelling down the cell to a draw-off pipe 21 and part travelling upwardly to a draw-off 25.  The pipe 17 may be situated near the jet or lower down the cell.  If desired the spinning solution may be heated and the filter-candle and spinning solution conduit between the heating device and the spinning jet may be surrounded with heat insulating material.  As shown in Figs. 3 and 4, a co-current of evaporative medium enters the cell through pipe 48, is constrained to pass close to the filaments in the region of the jet by means of the apertured plate 55, and is withdrawn through pipe 21 at the bottom of the cell.  Additional evaporative medium is introduced from the arcuate pipe 51 in the region of the jet 13 and passes across the path of the filaments to a draw-off pipe 56 at the opposite side of the cell.  As shown in Fig. 5, a co-current of evaporative medium enters the cell at 48 and is withdrawn at 21.  Additional evaporative medium is introduced in the vicinity of the jet 13 from the perforated annular pipe 62, and passes also down the cell in the direction of the filaments. The Provisional Specification refers also to the introduction of additional evaporative medium into the interior of a bundle of filaments and the setting up of a radial current.  Specifications 320,632, 323,790, 325,233, [all in Class 2 (ii), Cellulose &c.], 340,930, 341,075, and 342,712 are referred to.

Abstract: 188,173. Pomeroy, R. E. H. Oct. 13, 1921. Ball and like mills.-In apparatus for pulverizing cement, lime, coal, ores, minerals, &c. of the kind comprising a rotatable shell charged with balls, pebbles, rods, bars, or other loose grinding- devices, the finer particles being carried off by means of a current of air, the air is admitted through perforations or openings in the periphery of the shell and conducted through the material and grinding-devices. The air current may be passed through a separator and the heavier particles returned to the mill. As shown in Figs. 1 and 3, a stationary casing 12 surrounds the rotating shell 5 which is connected to end heads 6 having hollow trunnions 7 mounted in bearings 8. The shell is lined with metal liners 15 formed with air spaces 16 which communicate through slots 17 in the shell with the annular air-chamber 14 and through openings 18 with the interior of the mill. A series of longitudinal radial partitions 20 attached to the outer casing 12 and extending to near the shell 5 ensures that most of the air is forced through the mass of material and tumbling-devices 11 as the shell rotates. The ends of the chamber 14 are closed by annular flanges attached to the casing and shell respectively. The air with the fine particles in suspension is drawn through the outlet trunnion by an exhaust fan 24 and forced through a pipe 26 into a separator 27 from whence the coarser particles are returned by a pipe 28 to the feedmechanism 10 of the mill. The air carries the finest particles into a cyclone dust collector 30 and the deposited particles are received in a bin 31. The return-air pipe 32 is attached to the casing 12 by a flaring connection 36 at the side of the shell 5 next to the material. A smaller separator or cyclone collector 33 with a vent-pipe 34 may be connected by a branch 35 to the return pipe 32. In a modification, Fig. 6, an adjustable air-chamber 14<a> formed by a casing 12a surrounding the shell is rotatably supported independently thereof upon wheels 38. Circular tracks 39 on the casing rest upon the wheels 38 which are mounted in a frame 39a adjustably supported upon a base 40. A segmental rack 44, Fig. 8, on the casing meshes with a pinion 45 on a shaft 46 carrying a hand-crank 47, and the casing is locked in the desired position by a latch engaging a notched wheel 49 on the shaft 46. The lining is composed of longitudinal sections 15 formed with a base portion containing air spaces 16 and a raised portion having an inclined face with passages 18 for conducting the air into the interior of the mill, the passages 18 being substantially tangential to the rotating shell.
