Filed: 1951-07-26
Abstract: An easily processable composition comprises a homogeneous mixture of a vinyl halide polymer and 1 to 40 per cent. thereof of a hard tough resinous thermoplastic interpolymer of 50 to 90 per cent. of a styrene and 10 to 50 per cent. of an acrylonitrile. The vinyl halide polymer may be polyvinyl chloride, bromide or fluoride or a copolymer of a vinyl halide with up to 50 per cent. of the total of vinylidene chloride or bromide; trichloroethylene; vinyl acetate, chloracetate, propionate, chloropropionate, butyrate, benzoate or chlorbenzoate; acrylic, chloracrylic, methacrylic or ethacrylic acid, methyl, ethyl, butyl, n-octyl, 2-ethylhexyl or n-decyl acrylate, methyl or butyl methacrylate, methyl or ethyl ethacrylate, acrylamide, N-methyl or N,N-dimethyl acrylamide, methacrylamide, N-methyl or N,N-dimethyl methacrylamide, acrylonitrile, chloracrylonitrile, methacrylonitrile or ethacrylonitrile; styrene, dichlorostyrenes, vinyl naphthalene; dimethyl or diethyl maleate; vinyl methyl, vinyl ethyl, vinyl 2-chlorethyl or vinyl isobutyl ether; methyl, ethyl or isobutyl vinyl ketone; vinyl pyridine, N-vinyl carbazole, N-vinyl pyrrolidone; ethyl methylene malonate; ethylene or isobutylene.  Terpolymers, e.g. from 50 to 90 per p  cent. vinyl chloride, 5 to 45 per cent. vinylidene chloride and 5 to 45 per cent. of vinyl acetate or benzoate or an acrylic or methacrylic ester, may be used.  The second component may be derived from styrene, chloro-, alkyl or alkoxy-styrenes and acrylonitrile, methacrylonitrile, ethacrylonitrile or chloracrylonitrile.  Up to 20 per cent. of the total of a third monomer may be used to form terpolymers.  Mixing of the ingredients may be accomplished by blending the dry resin and sheeting out, by mixing solutions or dispersions of the resins and precipitating or coagulating or by polymerizing the monomers of one resin, adding the monomers of the other and continuing the polymerization to "overpolymerize" the second on the particles of the first.  The compositions may include plasticizers, e.g. di-2-ethylhexyl phthalate; stabilizers, e.g. cadmium naphthenate, basic lead carbonate, lead silicate and titanate, calcium silicate and strontium salicylate; fillers, e.g. titanium dioxide, whiting, carbon black and ground clay; waxes; lubricants; extenders and resinous substances. The compositions may be extruded on to wire or to form rigid tubes, or used for making gramophone records, films and compound sheets, or may be embossed and deep drawn.

Filed: 1927-07-04
Abstract: 273,769. Corkscrew Steel Fences, Ltd. July 2, 1926, [Convention date]. Void [Published under Sect. 91 of the Acts]. Twisting. - A bar-twisting machine for automatically twisting a bar through the requisite number of turns comprises a trigger which is set back a distance according to the number of turns and moved forward during the operation of the machine at a speed proportional to the rate of twisting to release the driving clutch and is then returned automatically to starting position. The machine shown is adapted to twist two bars at the same time, which bars are held at one end in chucks 6 on a stationary headstock C and at the other between clamps 40 and a floating central block on a movable tailstock D. Chucks 6 are mounted on shafts 23 driven by gears 7 from a pinion 8 driven through a clutch 9 from a pulley 10, the clutch being thrown in by a fork 16 actuated by means of a lever 11, link 12, rocker lever 13, link 14, and lever 15. The rocker-bar 13 carries a shaft 18 with a serrated setting disc 19, worm wheel 20 and pulley 21 fast thereon. A trigger lever 31 is mounted behind the disc 19 and moves with it, and an arm 32 moving freely on the shaft 18 carries a setting plunger 33 which can be moved by a nut 34 to engage the serrations of the disc. A weight 36 is hung from a wire 35 wound round the pulley 21 and attached to it. A shaft 17 above the worm wheel 20 carries a worm 24 adapted to engage with the worm wheel and is driven by a pinion 22 engaging a pinion on one of the chuckcarrying shafts 23. A trigger 26 mounted in fixed guides 27, 28 is urged forward by a spring 29; the forward end of the trigger coacts with a trigger catch 25 on the link 14 and a collar 47 on the trigger coacts with the trigger lever 31 behind the setting disc 19. In operation, the setting disc 19 is turned anti-clockwise through an angle, corresponding, with the number of turns the bars are to be twisted, and the plunger 33 on the loose arm 32 is engaged with the notch corresponding to that number. When the lever 11 is operated to throw in the clutch 9 the worm wheel 20 is moved into gear with the worm 24 and the trigger catch 25 rides over the trigger 26, which thereupon shoots forward under the catch 25 so as to retain the clutch 9 in engagement. The disc 19 is rotated in a clockwise direction by the worm and worm wheel until the twisting is completed, when the trigger lever 31 strikes the trigger collar 47, releases the trigger 26 from the catch 25 and permits the clutch 9 to be released by the weight of the clutch linkage or by an additional weight on the shaft 18. The setting- disc and trigger lever are then moved back to a fresh starting position by the weight 36, the arm 32 striking an adjustable stop 38 on the guide 27. The shortening of the bars during twisting pulls the tailstock up against an adjustable stop 43.
