  • Patent number: 5531506
    Abstract: A seating unit includes a seat frame, a foldable table assembly that includes a foldable panel pivotally attached to its rear edge, a four bar linkage which moves the table assembly between an open position and a closed position, and a roller which controls the rotational movement of the foldable panel about the rear edge of the table assembly. The seat frame includes a seat having a generally horizontal seat surface and a backrest having a recessed area and mounting panels positioned laterally of the recessed area. The foldable table assembly includes a decorative surface and a support surface generally opposed to the decorative surface. The foldable panel has an upper surface and a lower surface generally opposed to the upper surface.

  • Patent number: 5524959
    Abstract: A seating unit comprises a seat frame, a foldable table assembly that includes a foldable panel pivotally attached to its rear edge, a four-bar linkage for moving the table assembly between an open position and a closed position, and a roller and cloth hinge combination for controlling the rotational movement of the foldable panel about the rear edge of the table assembly. The seat frame, which comprises a seat and a backrest, includes a recessed area in the backrest with laterally positioned mounting panels. The foldable table assembly comprises opposed decorative and support surfaces and the foldable panel. The four-bar linkage is attached to the table assembly and to the mounting panels of the seat frame and moves the table assembly between a closed position, in which the table assembly is nested within the recessed area with the decorative surface facing forward, and a generally horizontal open position, in which the support surface faces upwardly.

  • Patent number: 4629475
    Abstract: Constant volume and therefore constant flow rate apparatus is provided for removing bubbles of gas from a process liquid that is used in the manufacture of a product where the presence of such bubbles has a detrimental effect on the quality of the finished product. Gas bubbles are removed from a liquid by passing the liquid through a bubble coalescing baffle, in a generally upward direction, and into a chamber situated directly above the baffle, the chamber having an upward sloping upper surface, and a gas vent at the upper portion thereof, that is laterally displaced a substantial distance in the direction of liquid flow from the center of upward liquid flow, for the purpose of continuously venting gas bubbles that have separated from the liquid without allowing a significant volume of gas to accumulate in the chamber and without allowing the liquid to exit through the gas vent.

  • Patent number: 4528939
    Abstract: The present invention is directed to a containment vessel which is particularly useful in melting aluminum. The vessel of the present invention is a multilayered vessel characterized by being electrically conductive, essentially nonwettable by and nonreactive with molten aluminum. The vessel is formed by coating a tantalum substrate of a suitable configuration with a mixture of yttria and particulate metal borides. The yttria in the coating inhibits the wetting of the coating while the boride particulate material provides the electrical conductivity through the vessel. The vessel of the present invention is particularly suitable for use in melting aluminum by ion bombardment.

  • Patent number: 4433917
    Abstract: An apparatus for automatically preparing a multi-ingredient mixture in batches in a mixing tank and providing a continuous supply of the mixture to a run tank in response to down stream demand. Gravimetric means provide monitoring signals indicative of the actual weight of the contents of each tank. Deviations from target ingredient ratios are automatically registered and compensated for in preparing each batch by logic control means which compare the actual weight of each ingredient added with a precalculated target weight, calculate target weights for the second and subsequently added ingredients on the basis of the actual amounts of ingredients added earlier and automatically activate the mixing tank outlet valve and the ingredient supply valves.
