Abstract: This relates to a hot runner manifold for distributing thermoplastic melts from a plasticizer to plural cavities of a mold. The manifold is formed in two parts which include a plate and a ring which are joined along a central parting line in a manner wherein all of the sprue and runner portions may be readily and accurately machined.

Abstract: An inlet line deflector and equalizer means for a cyclone for washing crushed and sized coal with water wherein low density (1.6 or less) washed coal particles escape through the outlet pipe above the bottom collector through the box of the cyclone while higher density (1.7 or higher) siliceous impurities drain out of the cyclone bottom. The higher density impure fractions may be recycled in another cyclone to further fractionate into purified coal and refuse. Pure coal particles flow out through the outlet pipe above the box and impure particles containing shale, rock, clay, etc. drain at the bottom. Laminar flow is uniquely created by (1) providing high solids of about 18% to 50%, (2) at high velocity of about 18 to 28 feet per second within the cyclone and (3) by placement of an inlet line deflector in a predetermined critical dimension in the intake pipe.

Abstract: Stock distribution means for delivering an aqueous slurry in a papermaking machine has a tapering passage which delivers stock to a nozzle by way of several rows of channels whose inlets are in communication with the passage. The passage, the entire channels and/or the inlets of the channels are configurated and dimensioned in such a way that the resistance which the inlets nearer to the intake end of the passage offer to the inflow of stock is more pronounced than the resistance of inlets which are more distant from such intake end. This insures uniformity or substantial uniformity of the volume of stock flow in each channel in spite of the fact that the channels of neighboring rows are at least partially inclined with respect to each other and that the inlets of channels in successive rows are located downstream of each other, as considered in the direction of stock flow in the passage.

The subdivision and twists are accomplished by mounting twisted pieces of flat bar stock in the conduit carrying the stream or substream, each piece having its input end positioned on the axis of symmetry of the stream at the point of stream division.
