Abstract: A filtering arrangement of thermoplastics extruding apparatus has a rotatable cylindrical screen unit through which material flows radially inwards and is discharged axially and an outlet aperture for impurities which are washed from the screening unit by reverse flow, i.e. radially outward flow, of part of the filtered material. The outlet aperture for the impurities is variable in cross-section by moving an arcuate segment about the axis of the cylinder to control the extent of reverse flow washing.

Abstract: A continuous foam production system is disclosed wherein a molten thermoplastic resin is mixed with volatile blowing agent at elevated pressure to form an extrusion mass. A helical screw extruder means is adapted to extrude the molten resin with volatile blowing agent into a low pressure foaming zone to form a foam sheet, tube or other shape. An improved fluid handling system includes storage means for holding at least one of a plurality of disparate volatile liquids under pressure sufficient to maintain a normally gaseous blowing agent in liquified state and cooling means for receiving a pressurized first stream of liquified thermally-gaseous blowing agent and cooling below its autogenous temperature. A pump operatively connected between the cooling means and extruder means increases pressure of the first stream higher than the elevated pressure of the extruder, where it may be combined with a pressurized stream of second liquid blowing agent. Flow control means is provided for injecting a predetermined amount of disparate liquid blowing agents from the first and second streams into the extruder means at elevated pressure to form an extrusion mass.
