Abstract: The flow control for fluid circuits having dual power outlets includes a housing having an interior compartment with the compartment having an interior surface, center portion and first and second ends. The compartment has a maximum cross-sectional area at its center portion uniformly decreasing in area towards the first and second ends. First and second outlet fluid ports are located in the housing adjacent the first and second ends. A pressure fluid inlet port is located in the housing at the center portion thereof. A flow control element is mounted for longitudinal movement in the interior compartment and has an outer surface symmetrical in shape to that of the compartment, but has a smaller diameter wherein a fluid flow space exists between the outer surface of the control element and the interior surface of the compartment.

Abstract: A conveyor for particulate material consists of a plurality of channel shaped air deflectors mounted in overlapping engagement on support beams. Each air deflector has a short lower flange, a longer upper flange and an interconnecting web. Protrusions on the bottom side of the upper flange maintains a gap between upper flanges of adjacent air deflectors. Air is forced through the gap between adjacent air deflectors so as to convey particulate material over the upper flanges thereof.

Abstract: A heat exchanger is disclosed comprising a plurality of spaced apart parallel plates having a plurality of apertures therein, a plurality of hollow frusto-conically shaped cone members having a larger base end and a smaller opposite end with the cone members being inserted in the apertures of the plate and being of such relative size to be tightly embraced by the peripheries of the apertures, the opposite ends of the cones in each of the plates being tightly nested and stacked in the base ends of the cones in the next adjacent plate, and means for fixedly securing the plates in parallel relation to bind the cone members in stacked relation.

Abstract: A method and means for burning corn and corncobs is described. The apparatus includes a conical or pyramidal shaped perforated floor having a central opening formed therein which is in communication with a first conveyor which supplies the material to be burned thereto. A second conveyor extends around the periphery of the floor for carrying away the ashes of the burned material. The first conveyor forces the corncobs or corn upwardly through the central opening to form a mound or pile of material thereon. The mound of material is ignited and air is forced upwardly through the perforated floor to enhance combustion so that the material is substantially completely burned. The products of combustion are passed upwardly through a heat exchanger and filtered through the material delivered to the first conveyor before being exhausted to the atmosphere.

Abstract: A wall structure comprising a plurality of vertically disposed and horizontally spaced columns secured to a supporting surface such as a floor or the like and extending upwardly therefrom. A vertically disposed panel member is positioned between adjacent pairs of the columns to create a wall surface. Each of the columns comprises a plurality of column members secured together by means of bolts to form the column. The panel members each have opposite side edge portions with arcuate lips or channels formed therein which are received between pairs of the column members and which engage flanges on the column members to prevent the separation of the panel members from the columns. Various embodiments of the columns are disclosed for creating corner columns, intermediate columns and dividing wall columns.

Abstract: The wall structure is comprised of a building panel which includes U-shaped side members each having a web portion and outwardly disposed spaced apart flange members with a plurality of sheet members extending between the web portions of the side members. The sheet members dwell in the same plane and the adjacent edges of the sheet members may be spaced from each other. Pairs of stiffener members extend between the side members on opposite sides of the sheet members and cover the adjacent edges of adjacent sheet members. The stiffener members have a beveled outer surface so that particulate material will not lodge thereon when the panel is in a vertical position. The stiffener members form an enclosed compartment along the adjacent edges of adjacent sheet members.
