  • Patent number: 8147689
    Abstract: A dewatering conveyor system for dewatering chunks of petroleum coke or the like material which is mixed with large volumes of water, wherein the conveyor employs lateral drag bars, the top flight of which conveyor slides forwardly on a screening deck having dewatering screens, and the bottom flight of which conveyor slides rearwardly on a sluice deck underlying the screening deck, wherein a major portion of the conveyor rearward of its discharge end is contained by tail end wall means and side and bottom wall means which can contain large volumes of coke and water, wherein, for handling large volumes of water the discharge end of the conveyor is elevated, e.g., up to 20 ft. or more above the tail end of the conveyor such that water dropping thru the screens will run down toward the tail end of the conveyor and leave the discharge end above the water line, and wherein a drain port is located thru the bottom wall means at a tail end portion thereof.

  • Patent number: 8088282
    Abstract: Disclosed herein are an apparatus and a method for separating molecules on the basis of size and or structure, and to a method of making the apparatus. Generally, the separation method includes passing a fluid comprising particles having different effective molecular diameters through a plurality of open, nanoscale channels disposed in surfaces of substrates. The method also includes obtaining a plurality of fractions of the passed fluid such that each of the fractions includes a major portion containing particles having similar size and shape and substantially free of particles having larger size and shape. The apparatus includes first and second substrates each of which has a surface containing a plurality of open, nanoscale channels disposed therein. The surfaces are bonded together such that each of the channels of the first substrate is in fluid communication with at least two of the channels of the second substrate and is misaligned relative to the channels of the second substrate.

  • Patent number: 8038879
    Abstract: A fluid strainer device is disclosed. The device includes a housing which defines an open chamber, the chamber having both at least one fluid input port and at least one fluid outlet port. A plurality of spaced strainer baskets are disposed within the chamber. Each basket has a pair of spaced perforated side panels, a perforated rear panel, a perforated top panel and an open front portion in fluid communication with the chamber fluid input port. Finally, each strainer basket is aligned within the chamber for fluid flow from the chamber input port into the basket's open front portion and out through the perforations thereof to filter debris from the fluid while preventing substantial fluid pressure drop between the input and outlet ports substantially independent of debris buildup within the basket.
