Title: Polymerisation catalysts
Inventor: DORLING SYDNEY
IPC: C08F4/58
Filed: 1961-06-29
Abstract: Polymerization catalysts are made by reacting a compound of a transition metal of Group IV-VI with at least one organic silicon compound containing the grouping <FORM:0934119/III/1> , where R is a phenyl radical which may bear substituent groups, and the remaining valency is satisfied by an aromatic, cycloaliphatic or aliphatic group or hydrogen.  The transition metals of Group IV-VI of the Periodic Table are defined as those metals occupying any of the 4th to 6th places after the inert gases in any of the long periods of the Table, the rare-earths occupying only one such place.  Specified silicon compounds are phenyl silane and diphenyl silane.  The preferred transition metal compounds are halides especially chlorides of aluminium, titanium and vanadium.  A particularly effective catalyst component is formed by combining a transition metal halide in a valency state lower than its maximum with a Lewis acid, e.g. TiCl4, VCl4 or AlBr3.  Prior to use the catalyst components may be ball-milled.  Specifications 830,424 and 877,050 are referred to.ALSO:a -Olefines are polymerized in the presence of catalysts made by reacting a compound of a transition metal of Group IV-VI of the Periodic Table with at least one organic silicon compound containing the grouping <FORM:0934119/IV(a)/1> where R is a phenyl radical which may bear substituent groups, and the remaining valency is satisfied by an aromatic, cycloaliphatic or aliphatic group or hydrogen.  The transition metals of Group IV-VI of the Periodic Table are defined as those metals occupying any of the 4th to 6th places after the inert gases in any of the long periods of the Table.  Specified silicon compounds are phenyl silane and diphenyl silane.  The preferred transition metal compounds are halides, especially chlorides, of aluminium, titanium, and vanadium.  The catalysts are especially useful for polymerizing ethylene.  By their use higher a -olefines may be polymerized to solids, semi-solids or oils.  Polymerization is preferably effected in an inert hydrocarbon solvent or unreacted liquid monomer in which the catalysts form slurries, at elevated temperature, e.g. 50 DEG -100 DEG C. or higher, and under superatmospheric pressure.  Since oxygen or water destroys the catalysts polymerization is effected in their absence.  Comparative examples are given.  Specifications 830,424 and 877,050 are referred to.

Abstract: 1531808 Cutting apparatus GARY STEEL PRODUCTS CORP 11 June 1976 [23 June 1975] 24320/76 Heading B4B [Also in Division B3] Strip 10 of metal or paper is cut from a coil 12 by a machine having a cutter 36 to which the strip is fed over a hump table 30 by a fast feeder 18, before operation of the cutter the strip being gripped between the rolls 40, 56 of a slow feeder which is then stopped for operation of the cutter, while the faster feeder continues to operate. As shown, the fast feeder 18 also levels the strip which slides over the lower, driven slow-feed roller 40 when the upper roller 56 is raised by pneumatic cylinders (58), 62. A roller 72 engaging the strip drives a pulse generator (encoder) 66 associated with counters and a control circuit, Fig. 5 (not shown). At a predetermined pulse count the upper roll 56 is lowered to make the slow feeder effective and at a larger count a clutch is disengaged and a brake applied to stop the rolls 40, 56. The shears 36 respond slightly slower to the control signal and the severed length is carried away at a faster rate than the fast feeder 18 by a discharge table 38. The control circuit resumes feed through the shears after a short delay. Instead of a pulse generator, two micro switches 100, 104, Fig. 6, may be tripped consecutively by the end 108 of the strip, switch 108 of the strip, switch 104 bringing in the slow feed and switch 100 stopping the slow feed and applying the shears. Both rolls of the slow-feeder may be driven, Fig. 11 (not shown), being coupled together by gearing. Instead of electrical signals, pneumatic or hydraulic signals may be used.
