  • Patent number: 4542189
    Abstract: A process for the preparation of rubber-modified thermoplastic compositions having high temperature stability includes the steps of dissolving a rubber polymer in a solvent selected from the group consisting of monovinyl aromatic monomers, olefinically unsaturated nitriles and mixtures thereof to form a feed solution, introducing the feed solution into a reactor capable of intimately mixing multiple immiscible phases, introducing into the reactor a separate liquid monomer feed stream containing monomers selected from the group consisting of unsaturated dicarboxylic acid anhydrides, olefinically unsaturated nitriles and mixtures thereof, heating the feed solution and feed stream under pressure to a temperature sufficient for polymerization to begin and intimately mixing and polymerizing the monomers around the rubber polymer in the reactor to form a thermoplastic resin composition.

  • Patent number: RE31505
    Abstract: A control device for a continuous processing line which is fed material from a coil utilizes information regarding the outside diameter of the material on a coil having a constant inside diameter as a basis for its control functions. A typical application is in the control of a strip accumulator (15) in a strip processing line wherein strip(s) on a revolvable coil is drawn from an uncoiler (10) by the revolvable pinch rolls (16) of the accumulator at which point a certain quantity of material is stored so that when the end of a coil is reached a new coil may be attached to the old coil without stopping the line. In such instances it is highly desirable that the accumulator be substantially filled so that a maximum time is available to attach the new coil. The control device includes means (31) providing a signal proportional to the revolutions of the pinch rolls and means (30) providing a signal proportional to the revolutions of the supply coil.
