Abstract: Linear oily polymers and copolymers of a diolefin having 4-6 carbon atoms in the molecule, e.g. of M.W. 2000-5000, are made in yields up to 80 per cent by polymerizing in bulk, or in the presence of an organic diluent, the diolefin alone, or admixed with a copolymerizable compound containing a single >C=C< group, at a temperature between 50 DEG  and 150 DEG  C., under superatmospheric pressure, e.g. 3-30 atmospheres, in the presence of a catalyst of formula <FORM:0677774/IV (a)/1> where R represents a methyl, phenyl, or tolyl group and R1 represents hydrogen or a benzoyl group and, optionally, purifying the product to remove minor amounts of dimer and insoluble polymer.  The polymerization may be effected in the presence of modifiers such as diisopropyl xanthogen disulphide and flowers of sulphur.  Specified catalysts are o-, m-, or p-cymene hydroperoxide, cumene hydroperoxide, t.-butyl hydroperoxide, t.-butyl perbenzoate and cumene perbenzoate.  The diolefin may be butadiene-1,3, isoprene, piperylene, dimethylbutadienes, methyl-pentadienes, dicyclopentadiene, chloroprene, bromoprene and mixtures.  Specified compounds containing a single >C=C< group are ethyl fumarate, and maleate, methyl acrylate and methacrylate, acrylo- and methacrylonitrile, vinyl acetate, vinyl chloride, vinylidene chloride, trichloroethylene, vinyl isobutyl ether, styrene, o-methyl and p-methyl styrene, mono- and di-chlorostyrenes and chloromaleic anhydride.  The diluent which need not be inert, may be benzol, xylene, toluene, butane, cyclohexane, solvent naphtha, chloroform, carbon tetrachloride or halogenated hydrocarbons boiling between 60 DEG  and 200 DEG  C.  The polymers may be used as adhesives, in printing inks, as air drying protective coatings, e.g. for metals, and as vehicles for enamels and paints admixed with conventional solvents, pigments and driers.

Abstract: 1374555 Cutting apparatus GERBER GARMENT TECHNOLOGY Inc 14 May 1973 [2 Aug 1972] 22846/73 Heading B4B  A transfer table 10 for moving a carriage 16 for a tool 14, e.g. a reciprocable blade 14, between a plurality of work-tables 12 having ways 42 on which the carriage moves along while performing a work operation, the table including supporting ways 40 on a frame and a set of wheels 36, 38 to enable the ways 40 to be substantially aligned with the ways 42 but spaced therefrom and means 54, 56, 58, 60 connected to the frame for moving the ways 40 into engagement with the ways 42 when so aligned. The wheels are adapted to run on rails 30, 32, Figs. 1 and 2 in order that the transfer table can be aligned with any of the tables 12 so that the carriage 16 can be transferred thereon. The table is locked to the end of the particular work-table 12 by means of a pair of locking handles 70, Fig. 4, engaging with hooks (72), Fig. 5 (not shown), on the work-table. The carriage is driven back and forth on the work-table by means of a motor-driven pinion engaging a rack 22, the latter motor and a motor 94, Fig. 6, for the knife 14 being controlled by a computer 18; the computer is connected to the carriage via cabling 20 suspended from a system of overhead tracks. When it is required to transfer the carriage from a work-table to the transfer table, an overrun stop 102, Fig. 6, on the work-table and limit-switch actuating cams 126, 128 are moved out of their operative positions by means of a foot-pedal actuated linkage 108. The carriage can now be moved under power on to the transfer table; the movement of the carriage on the transfer table is limited by engagement of a roller 87, Fig. 4, on the carriage with a stop 82 on the table; a manually-operable latch 80 is then operated to lock to carriage against the stop. Before moving the transfer table along the rails to the next table, the ends of the ways 40 and rack 44 must be moved out of contact with the corresponding ways 42 and racks 22 of the worktable. This is effected by means of a jacking system 56, 58, 60, Fig. 3, which, when a hand wheel 54 is rotated, tilts the transfer table as a whole after the locking handles have been released. In a modification of the transfer table (250), Fig. 10 (not shown), the guideways (264) are mounted on a frame (254) which is movable on a chassis (252) via rollers (260) so that the guideways can be engaged with the ways on the work-table. The transfer table is locked to the work-table by means of a pin (280) on a shaft (272) engaging with a locking plate (274) on the work-table 12. When the carriage is driven on to the transfer table and as it approaches the stop 82, the roller 87 on the carriage contacts a cam (290) so as to rotate the shaft (272) and thereby disengage the locking pin (280).
