Abstract: An improved blending apparatus for manufactured wood products with a rotating blending drum or cylinder with a pattern of alternating flights of different configurations extending from the interior of the drum. The flights lift the strands as the drum rotates to different heights before the strands free-fall back to the bottom of the drum. One flight is shorter, and may be trapezoidal in cross-section. The second flight is taller, and may have a “bull-nose” configuration with substantially vertical sides. During operation, the design of the bull-nose flight tends to hold more strands and to carry them closer to the top of the drum before the strands drop and fall. In contrast, the shorter height and angled sides of the trapezoidal flight tends to hold fewer strands and to not carry them as high along the side before strands drop and fall.

Abstract: The present invention relates to an apparatus and method for separating and processing solid waste, often but not necessarily from municipalities (and so will be generically referred to herein as municipal solid waste or “MSW”), into useful products, and for reducing biohazards and putrid odors derived from MSW. The MSW is loaded into an elongated, generally cylindrically shaped rotating pressure vessel and is subjected to heat and pressure by the application of steam in specified amounts to break down the organic portion of the MSW into a cellulose feedstock, or a de-manufactured paper product, of uniform particle size and density. This product is then easily separable from other constituents of MSW, such as glass, aluminum and other metals, and plastics. The recyclables are recovered and sold in the market. The waste water from the process is reduced by processing through a water vamping apparatus.

Abstract: A massage plant for the processing of chunks of meat includes a container (22) which is rotatable about its longitudinal axis and includes axially or substantially axially extending interior conveyors (16), each made as a hollow profile containing internal channels.
