摘要： Novel and improved methods and apparatus for processing liquid or viscous materials. Essentially, the methods and apparatus involve feeding liquid materials to an annular processing passage for controlled processing. The annular processing passage is provided by two elements. One is a rotatable element carrying at least one processing channel. The other element is stationary and provides a complementary coaxial surface arranged with the channel to provide the enclosed processing passage. Also associated with the stationary element are an inlet for feeding material to the passage, an outlet for discharging material from the passage, an element near the outlet providing a material collecting end wall surface and an element positioned between the inlet and outlet providing a liquid material spreading surface. Rotation of the rotatable element toward the spreading surface provides a coaction between the rotatable element and the spreading surface so that relative movement is established between the rotating inner channel walls and liquid material between the inlet and the spreader surface. Because of the relative movement, the liquid material is spread toward the walls and dragged by the walls through a clearance between the sides of the spreading surface providing member and the side walls as thin layers providing central spaces of the passage downstream of the spreader surface which are free of liquid material. Means are arranged for communicating with the free central spaces to add materials to or withdraw materials from the free central space.

摘要： An extruder machine for processing thermoplastic materials such as low density polyethylene, the extruder incorporating a body having a bore therethrough with a rotor or screw journalled therein. The rotor has several successive mixing and pumping sections. The mixing sections on the rotor are multiple flighted defining primary and secondary channels having their discharge and entrances respectively blocked or restricted by annular dam arrangements. The rotor includes a plurality of adjustable dams, arranged across the channels, permitting a variation in the degree of homogenization which may be performed upon the extrudite. The dams may be radially displaceable to vary the distance between the radially outer surface of the dam and the surface of the bore.

摘要： Sealing means for controlling leakage of material between closely spaced apart, relatively moving coaxial annular surfaces. Essentially, leakage is controlled by providing a pumping channel on one of the surfaces and a leakage liquid retaining channel on the other surface. The pumping and leakage liquid retaining channels are cooperatively arranged to resist flow of leakage liquid between the surfaces. The sealing means are particularly adaptable for controlling leakage from processing passages of rotary processing apparatus.

摘要： Novel and improved processes and apparatus for processing particulate materials which can be converted to the liquid state. Essentially, the process and apparatus involve feeding a particulate material to an annular processing passage for melting and controlled processing. The annular processing passage is provided by a rotatable element carrying at least one processing channel, and a stationary element which provides a complementary, coaxial surface arranged with the channel to provide the enclosed processing passage. Also associated with the stationary element are an inlet for feeding material to the passage, an outlet for discharging material, a material collecting end wall surface for the passage and a member or members extending into the processing channel providing a material restraining surface between the inlet and outlet and occupying a predetermined portion of the melt pool space between the end wall and the restraining surface. Rotation of the rotatable element establishes relative movement between the rotating inner channel wall surfaces and the restrained particulate material, causing only liquid (melted) material in contact with the rotating channel walls to be dragged forward to the end wall surface for controlled processing and discharge. Controlling the size of the melt pool space provides control of processing characteristics for the liquid material collected in the melt pool space.

摘要： Improved means for aligning processing members at various positions in processing passages of rotary processors. Essentially, the alignment means (or alignment elements) comprise a non-rotatable member positioned in the processing passage and shaped to at least partially interfere with flow of material in the passage. The shaped member is designed to perform certain processing functions on material in the passage such as blocking, collecting, mixing, spreading, restraining etc. The member is positioned so as to be non-rotative with the passage but is flexibly supported so as to "float" axially in the passage and is self-centering in the passage by hydrodynamic action.

摘要： An extruder machine for processing thermoplastic materials such as low density polyethylene, the extruder incorporating a body having a bore therethrough with a rotor journalled therein and having several mixing and cooling sections set thereon in succession. The mixing sections on the rotor are multiple flighted defining primary and secondary channels having their discharge and entrances respectively blocked or restricted by annular dam arrangements. The bore includes a plurality of annular grooves of symmetrical or non-symmetrical cross-sectional configurations along the axis of the bore which grooves are slightly displaced in the bore with respect to the annular restrictions disposed on the rotor. The rotor, however, is axially displaceable to permit variations in the mixing intensity upon the extrudite being worked, by allowing the annular restrictions on the rotor to be controllably juxtaposed with the annular grooves in the bore of the extruder machine.
