Patent GB-976887-A (GB)
Title: A process for the copolymerization of more than two olefinically unsaturated hydrocarbons
IPC: C08F210/00
Filed: 1962-07-03
Abstract: Copolymers of ethylene with propylene and/or butene-1, with one or more further alpha-olefins containing at least 5 carbon atoms are made by employing a copolymerization catalyst consisting of one or more compounds of a transition metal and an organometallic compound of Group IA, II or III, of the Periodic Table by first mixing all or part of the alpha-olefin containing at least 5 carbon atoms with one or more of the catalyst components before the latter are contacted with ethylene, propylene, and/or butene-1.  The polymerization is effected in liquid diluents. The alpha-olefin mixed with the catalyst components may be octene-1, dodecene-1, hexadecene-1, or mixtures, and the mixing is preferably effected between 40 and 150 DEG C. Many catalysts are mentioned, those exemplified are gamma TiCl3 + Al(C2H5)2(OC2H5), VOCl3 + aluminium isobutyl sesquichloride, gamma TiCl3 + Al(C10H19)3, and VCl4 reduce with Al(C2H5)2 Cl + Al(C2H5) Cl.

Abstract: 1,152,114. Induction heating. SCHLOEMANN A.G. 2 June, 1967 [15 June, 1966], No. 25605/67. Heading H5H. In an inductively heated billet-container for an extrusion press having longitudinally extending conductor bars mounted in circumferentially spaced longitudinal bores 4 in the wall of a cylindrical jacket 3, overheating in the central part of the jacket is prevented by the interposition of electrically insulating material between the bars and the bores 4, the crosssection of insulating material being greatest in the central part of the jacket. Adjacent bars are connected together at their ends to form a zig-zag winding. In the arrangement shown the diameter of the bore 4 in the central section is greater than in the end sections. The space between each bore and conductor bar is filled with insulating material. Alternatively the diameter of each bore may be uniform whilst the diameter of the central section of each conductor bar is reduced. In another arrangement having uniform diameter bores and conductor bars each conductor bar is surrounded at its ends by conducting sleeves and at its central section by an insulating sleeve.

Title: Improved method of detaching individual form units from a continuous stationery web
Inventor: JONES KENNETH WARNER
IPC: B26D7/18
Filed: 1950-10-27
Abstract: 681,413. Cutting paper webs. WARNERJONES & CO., Ltd., K. Oct. 29, 1951. [Oct. 27, 1950] No. 26277/50. Class 31 (i). A method of detaching individual printed form units 2 ... 6 from a transversely perforated continuous stationary web 1 consists in subjecting the web to a double guillotine action which cuts the web twice to each major feed of the web through the separating machine, the two cuts being effected in the region of each cross perforation line 7 ... 10 and taking place on opposite sides and close to such line. The web is moved forwardly by means of feed rollers 13, 14 and an auxiliary pull through rollers 23, 24. The movement of the web is stopped for the first cut with the respective line 7 of perforations slightly in the rear of a movable knife 11 co-operating with a fixed knife 12. After the first cut of the knife 11 and its return to its normal position, a looper roller 15 rises and permits the web to be straightened out by the auxiliary pull through the rollers 23, 24, the leading portion of the web being thereby moved to a position where the line 7 is located slightly forward of the knife 11 whereupon the latter descends to cut off a narrow strip, including the line 7, from the web. The cycle of operations continues, with the web moving through the machine, by a succession of alternate long and short steps. The cut-off unit may be of rotary type with two knives in which case the feed of the web takes place continuously in timed relation with the cutting mechanism. As the web passes through the machine, its side edges are preferably trimmed by means of rotary trimmers or circular cutting knives. In a modification, Fig. 6 (not shown), the looper roller may be mounted on arms fast with a cross shaft and move through a circular path. The arms may be duplicated to carry a second looper roller.
