Abstract: A pressure device for conduction of the cable in cable traction transportation systems including a pressure-roller (12) of the cable (7) supported elastically on a fixed support (2) and a counter-roller (6) supported on the fixed support (2) is described. In accordance with this invention the counter-roller (6) is supported in a revolving manner on a roller-holder (5) articulated at one end to the fixed support (2) and possesses at the other end guide means (8, 9) that engage as a running guide an arm (10) that bears in a revolving manner at one end the pressure-roller (12) on the side opposite the counter-roller (6) and is articulated at the other end to the fixed support (2) with the arm (10) being pressed by elastic means in the direction of exertion of pressure of the pressure-roller (12) on the cable (7).

Abstract: A clear impact resistant molding compound which does not become cloudy under either the influence of heat or moisture or on weathering and is composed according to the invention of:A) 10 to 90 percent by weight of a continuous rigid phase, essentially of methyl methacrylate, having a glass transition temperature greater than 70.degree. C. andB) 90 to 10 percent by weight of an elastomeric phase, distributed in the rigid phase and partly bound thereto, having a glass transition temperature below -10.degree. C., an average particle size of the elastomeric phase below 130 nm, and an inhomogeneity, U, of the elastomeric phase particle size of less than 0.5, comprising at least 50 percent by weight of B) of a lower alkyl acrylate and 0.5-5 percent by weight of a graft cross linking agent or an at least trifunctional cross linking agent,C) not more than 0.05 percent by weight of water soluble components,where U=D.sub.w.sup.3 /D.sub.n.sup.3- 1D.sub.w and D.sub.

Abstract: A method for making a thermoplastically processable polymer by emulsion polymerizing at least 80 percent by weight of methyl methacrylate monomer with up to 20 percent by weight of at least one other monomer in an aqueous phase at a temperature from 0.degree. C. to 100.degree. C. in the presence of a polymerization initiator and a chain transfer agent in a molar ratio from 1:2 to 1:100,000, said chain transfer agent being from 0.01 to 5 percent by weight of said monomers, and then separating said polymer and said aqueous phase.

Abstract: What are disclosed are a continuous emulsion polymerization method for making an aqueous dispersion of an impact resistant resin, adaptable to use as a component of impact resistant polymethacrylate forming masses, by first emulsion polymerizing a first monomer component onto core particles of a seed latex until a degree of polymerization of said monomers from 80 to 95 percent is attained, whereby an intermediate product comprising said core particles covered with a rubbery polymer phase is obtained, and then emulsion polymerizing a second monomer component onto the particles of said intermediate product to form a shell of harder polymer on the particles of said intermediate product, and impact resistant resin products made by this method.

Abstract: An emulsion polymer comprising a hard nonelastomeric core, an elastomeric intermediate stage produced in the presence of the core and essentially composed of an acrylic ester and a crosslinking monomer which contains three or more acrylic or methacrylic groups in the molecule, and a hard nonelastomeric final stage produced in the presence of the elastomeric intermediate stage and crosslinked therewith, said polymer being useful as an impact strength modifying agent which, in admixture with a thermoplastic polymethyl methacrylate molding compound for example, yields molded articles exhibiting reduced susceptibility to stress whitening and improved impact strength.
