Abstract: A molded body is produced on the basis of a raw material, the main content of which is material which is left after remolding pulp from paper and extraction of fibers from the pulp mass for remanufacturing of paper. This raw material which mainly consists of water, short fibers, and fine, mineral particles is drained by pressing in a first pressing stage between filter belts for production of a coherent body, is dried partially in a first drying stage is pressed and in a second pressing stage, and dried finally in a second drying stage. The invention concerns a similar method for separation of fibers and particles from waste water which results from repulping paper and reclaiming of fibers from the pulp mass for remanufacturing of paper, whereby an enviromental problem is solved in a very suitable way.

Abstract: A wood-plastic composite material is produced in a twin screw extruder with parallel intermeshing segmented screws. The screw segments are positioned on two spline shafts and perform the various required functions of mixing, deaerating and removal of moisture followed by extrusion. A polymer is fed to the main throat of the extruder where the plastic is conveyed along a barrel formed by the case of the extruder. Cellulosic fiber is positively fed into the extruder approximately one-quarter of the way down the extruder barrel by a twin screw side stuffer. A vent is provided for entrained air in the cellulosic material to escape. The molten mixture of polymer and cellulosic material is then conveyed to a devolatilization area having a first atmosphere devolatilization area and a second vacuum devolatilization area separated by a melt seal.

Abstract: A mortar and debris collection device for a cavity wall construction has a non-water absorbent body formed with circuitous paths therethrough making the body water-permeable. The collection device has a porosity sufficient to permit water to pass therethrough but insufficient to permit mortar and other debris to pass therethrough to weep holes or other water channels covered by the collection debris. The device may be freely placed on the wall base within the cavity to cover the opening of a weep hole, or may also be placed on existing wall ties within the cavity.

A molding base defining an internal molding cavity is provided with a pivotal closure also defining an internal die cavity. A forming die is movably supported by the closure and is movable from a retracted position out of the molding cavity to an extended position within said molding cavity where the forming die applies mechanical pressure to the soap fragments. The forming die is receivable within the die cavity at its retracted position and has a concave die surface of a configuration for forming a portion of the soap bar. A die actuator extends through the closure and may be provided with a spring for retraction of the die or for urging the die in a direction for continuous application of molding force to the forming die for a sufficient period of time for adhering and forming the soap bar fragments so as to define a resulting soap bar for subsequent conventional use.
