  • Loop reactor settling leg system for separation of solid polymers and liquid diluent
    Patent number: 4613484
    Abstract: Method and apparatus for the separation of solid particulate polymer from liquid diluent comprising the use of one or more accumulator legs to which diluent is supplied, and separated diluent is recycled to the polymerization process.
    Type: Grant
    Filed: November 30, 1984
    Date of Patent: September 23, 1986
    Assignee: Phillips Petroleum Company
    Inventors: C. A. Ayres, John N. Scott, Jr., Fred T. Sherk
  • Mold apparatus
    Patent number: 4129282
    Abstract: A mold apparatus for forming a molded article comprising a hollow body of a crosslinked polymer rotationally molded around a section of at least one piece of non-crosslinked conduit, which conduits protrude from said hollow body, made by attaching said conduits of non-crosslinked material at the desired location to the mold with said section being located inside a heated section of the mold so that the crosslinkable polymer during a rotational molding process is fused and crosslinked inside of the mold and around and in tight welding-type connection with said section, whereas the remainder of the piece or pieces of uncrosslinked polymer are heat-insulated, thus avoiding deformation or collapsing of these pieces.
    Type: Grant
