  • Patent number: 8112461
    Abstract: An electronic catalog is provided that stores items and attributes associated with the items. One or more of the attributes may have more than one value. Items are stored in an item table with different attributes for items stored in different rows in an attribute table. Additional items may be added to a catalog by adding additional rows to the item table, with attributes related to the additional items added as rows into the attribute table. Particular attributes may have multiple values, and attributes with multiple values are associated with sub-items that correspond to different attribute trees or attribute sets associated with the item. Searching can be performed for attribute values and search results returned indicating all items and sub-items that satisfy the search criteria.

  • Publication number: 20110132205
    Abstract: A cooking grid assembly includes a frame having first and second frame portions. The first and second frame portions each have one of a plurality of notches and a plurality of holes formed therein. A plurality of rods have first and second ends, such that the first end of each rod is disposed in one of the notches and holes of the first frame portion. The second end of each rod is disposed in one of the notches and holes of the second frame portion. A locking bar is removably attached to one of the first and second frame portions. The locking bar is movable between a closed position wherein the rods are retained in the one of the notches and holes, and an open position wherein the rods may be inserted and removed from the one of the notches and holes. An extension member is provided that is fixed to and outwardly movable relative to the frame to provide support to the frame.

  • Patent number: 6927354
    Abstract: An apparatus for tribocharging particles of electrically insulating materials has a rotatable drum (1), made of a metallic material, for containing the particles. The drum has an inlet (11), for charging material, and an outlet (13), for discharging material. The drum further has means (7) for rotating the drum about an axis of rotation, the orientation of the axis of rotation being such that, in operation of the apparatus, the particles tumble against each other and against the walls of the vessel, thereby becoming tribocharged. A fines removal mesh screening means (10) is attached to an outer surface of the drum, allowing fines to escape from the drum. An electrostatic separation tower (20), having tapering walls and at least one pair of electrodes (24) arranged on opposite walls of the tower, is aligned to receive discharged material from the drum. The tower separates the particles, falling from the drum into the tower (20), in an electric field generated between the electrodes (24).

  • Patent number: 6820566
    Abstract: An armor-protected buoyancy module is installed in multiple unit sets on tracked or wheeled vehicles to provide the vehicles with amphibious capability. The buoyancy modules can be lifted by two men without additional material handling equipment. The buoyancy modules are attached to fixed mounting devices that are mounted on the subject vehicle. Existing armor elements may be present to serve as the mounting devices. The armor shell provided for the buoyancy module protects it in both the deployed and stowed configurations.
