Title: Improvements in and relating to polymerisation
Inventor: TAYLOR KENNETH JOHN
IPC: C08F4/64
Filed: 1961-09-25
Abstract: Chelate complexes of a metal of Group IVA, VA and VIA of the Mendeleeff Periodic Table with a polydentate chelate compound which is at least tridentate are used as components of polymerization catalysts.  Polydentate compounds mentioned are tripyridyl, 2-alpha-pyridyl - 8 - hydroxy - quinoline, azo - bisortho - hydroxybenzene, ortho - hydroxybenzene - azo - beta - naphthol, and the trimer obtained from the condensation of paramethyl N-methyl aniline and formaldehyde. Metals mentioned are titanium, chromium, and cobalt. The complex of chromium trichloride and azo - bis - ortho - hydroxybenzene is stated to exist in two forms.  In examples, a chromium complex is made by dissolving ortho-hydroxy - benzene - azo - beta - naphthol and chromium trichloride hexahydrate in ethanol, refluxing the solution for 23 hours, adding toluene dried over sodium, and removing the ethanol by distillation, and a titanium complex by mixing in toluene, TiCl4 and ortho-hydroxy-benzene-azo-beta-naphthol.ALSO:A polymerization catalyst for olefines comprises the reaction product of (1) a hydride or organometallic compound of a metal of Group I or II, of the Mendeleeff Periodic Table, or aluminium, and (2) a chelate complex of a metal of Group IV(a), V(a), or VI(a) of the Periodic Table with a polydentate chelate compound which is at least tridentate, i.e. a compound which can make three bonds with a metallic atom and, in so doing creates two rings in the complex. The polydentate compound may be tripyridyl, 2-alpha-pyridyl-8-hydroxy - quinoline, azo - bis - ortho - hydroxybenzene, ortho - hydroxy - benzene - azo - betanaphthol, or the trimer obtained from the condensation of paramethyl - N - methyl aniline and formaldehyde.  The chelate compounds exemplified are obtained by reacting ortho - hydroxy - benzene - azo - beta naphthol with chromium trichloride hexahydrate, or with titanium tetrachloride.  The organometallic compound specified is diethyl aluminium chloride.  The olefine may be ethylene, styrene, butadiene, or isoprene.  The polymerization may be effected in a hydrocarbon diluent.

A valve has a sealing element constituted by two part-cylindrical members having their longitudinal edges spaced apart, the element being capable of radial movement within the valve housing and having a radius of curvature greater than that of a bore of the housing so that when the valve is in the closed position fluid under pressure is in direct contact with that part of the element communicating with the outlet side of the valve whereby it is pressed against its seating to form a complete seal. Figs. 1 and 3 show a rotary cylindrical valve having a ported bush 2 divided by a longitudinal cut 14 and having ports 5, 6 which can be aligned with openings 7, 8. The valve is operated by a rotary shaft 16 carrying a plate 15. A cross-bar 21 of rectangular section loosely engages slots in the plate and bush respectively. Fig. 4 shows a piston or gate valve comprising two part-cylindrical members 36, 361 embracing a reduced part 42 of a piston having an upper part 44 connected to a non- rotatable threaded spindle 53 and a lower part 45 with a through port 46 co-operable with inlet and outlet ports 37, 38. The spindle 53 is operated by a non-rising nut 55 and a hand wheel 54. The ends of the piston are open to the atmosphere and sealed with respect to the cylindrical surface 39 by ring gaskets 47, 48 backed by bush-like washers 51, 52. Rotation of the members 36, 36<SP>1</SP> relative to the piston is prevented by screws 43.

Abstract: 1284387 Endless conveyers; elevators MAC MFG CO Inc 14 July 1970 [11 Aug 1969] 34009/70 Headings B8A and B8H A mobile apparatus for raising and lowering barrels to and from a storage rack comprises a wheeled framework supporting a pair of endless chains 21 between which are mounted barrel cradles 25. The barrels are delivered to or removed from the apparatus along rails cooperating with a loading and unloading device mounted on the base of the apparatus and comprising a pair of frames mounted on either side of the rails and being vertically movable under the action of an hydraulic ram operating through chains 56. Each frame has a pivotable lever 50 with a control arm 49 arranged such that when the frame is raised the arm 49 abuts a stationary frame member 53 and causes the lever to rotate and thereby transfer the barrel to a cradle 25. The operation of the loading and unloading device is controlled by a switch LS-1 which monitors the presence of a barrel on the frame and a switch LS-2 which monitors the presence of a cradle in the barrel receiving position. A further loading and unloading device is arranged to move vertically along the opparatus under the influence of an hydraulic ram 135 acting through chains 150 to provide a variable height. The further device comprises a platform 8 with a guard rail 82, 84 for a workman and a table 83 with an extension 99 extending into the path of the endless chains to feed or discharge articles thereto. A removable frame 103 may be positioned on the extension to disengage the barrels from the cradles and cause them to roll on to the table. The table is provided with two pairs of rollers 87, 88 each pair being linked to an operating pedal 98 such that with a barrel positioned on said rollers, the depression of the appropriate pedal will cause a pair of rollers to move downwardly whereupon the barrel will be caused to roll in the direction of that pair of rollers. A telescopic frame 79 mountable on the guard rail 82 and the table 3 receives the barrels from the table and delivers them to the racks. To facilitate manoeuvring of the apparatus it may be pivoted into a substantially horizontal position by means of a ram 225 whereupon it may be towed by a tractor coupled to a spigot 276. In an alternative embodiment, Fig. 13 (not shown), the loading and unloading device (40) comprises a pair of rollers (303) on a movable frame and arranged to raise a barrel against a stationary guide (315) to allow a cradle (26) on an intermittently driven conveyer to pass underneath and receive the same.

Abstract: 1,249,573. Purifying acid mine water. BLACK, SIVALLS & BRYSON Inc. 8 July, 1969 [17 July, 1968], No. 34464/69. Heading CIA. [Also in Division C7] A process for removing the sulphur content from sulphate-containing acid mine water, comprises neutralizing the water with a limecontaining slag, thereby precipitating the sulphate ion-containing solids, recovering and drying said solids, reducing the sulphate ion in the dried solids, to sulphide ion, oxidizing the sulphide ion to sulphur wherein the reduction is achieved by introducing the dried solids into a bath containing molten iron and carbon. The carbon in the bath may be introduced in the form of carbonaceous fuel which may optionally contain sulphur or pyrites which are converted to sulphides and molten iron, respectively. The heat for the process may be supplied by burning carbon monoxide produced in the reduction, to carbon dioxide. The precipitated sulphate ioncontaining solids are in the preferred embodiment, recovered from the mine water by distilling off the water. The oxide containing slag remaining after the oxidation of the sulphides to sulphur (oxygen originates from the reduction of sulphates to sulphides) may be used to neutralize the acid mine water and the resulting slag, with or without sulphate containing solids otherwise removed from the mine water, is introduced into the bath of molten iron. The sulphides may be converted to sulphur by contact with water to generate hydrogen sulphide, oxidation of part of the H 2 S to SO 2  and reaction of the remainder of the H 2 S with the SO 2  to produce sulphur. The process carried out in the bath of molten iron is preferably similar to that described in Specification 1,225,206.
