  • Polypropylene composite
    Patent number: 9309395
    Abstract: Fiber reinforced composition comprising (a) a polypropylene random copolymer comprising ethylene and/or C4 to C8 ?-olefin (PP-RACO), (b) fibers (F), and (c) a polar modified polypropylene as adhesion promoter (AP), wherein (i) the polypropylene random copolymer comprising ethylene and/or C4 to C8 ?-olefin (PP-RACO) heaving a melt flow rate MFR2 (230° C.) measured according to ISO 1133 of at least 5 g/10 min, (ii) the fibers (F) are selected from the group consisting of glass fibers, metal fibers, ceramic fibers and graphite fibers, and (iii) the polymer contained in the reinforced composition forms a continuous phase being the matrix of the fiber reinforced composition.

  • Cyclone including an inlet diffuser tube
    Patent number: 5466372
    Abstract: A wet cyclone having a slender body with a truncated cone at an end thereof includes a heavy fraction outlet at an apex of the truncated cone and an immersion tube on the other end of the body. The immersion tube is cylindrical for withdrawal of a light non-gaseous fraction. A diffuser within the immersion tube deflects the flow within the tube for recovery of pressure head. The diffuser is disposed at a distance from the inlet end of the immersion tube of at least about half the inside diameter of the immersion tube.
