  • Patent number: 6514296
    Abstract: A dry preunit (10), includes a plurality of cells (110, 112, 114) in a true bipolar configuration, which are stacked and bonded together, to impart to the device an integral and unitary construction. Each cell (114) includes two electrically conductive electrodes (111A, 111B) that are spaced apart by a predetermined distance. The cell (114) also includes two identical dielectric gaskets (121, 123) that are interposed, in registration with each other, between the electrodes (111A, 11B), for separating and electrically insulating these electrodes. When the electrodes (111A, 111B), and the gaskets (121, 123) are bonded together, at least one fill gap (130) is formed for each cell. Each cell (114) also includes a porous and conductive coating layer (119, 120) that is formed on one surface of each electrode. The coating layer (119) includes a set of closely spaced-apart peripheral microprotrusions (125), and a set of distally spaced-apart central microprotrusions (127).

  • Patent number: 6506482
    Abstract: A reinforced vitreous carbon composite suitable for use in the formation of wear-resistant assemblies, such as joint prosthetic devices, bearings, current collectors, sealing components, brake linings, electrical motor brushes, and other tribological products. The reinforced composite is formed by impregnating a metal reinforcement structure with a furfuryl alcohol resin, and polymerizing the resin while thermally managing the polymerization process, to produce a poly(furfuryl) alcohol continuous phase that is isotropic, homogeneous and essentially completely void-free, e.g., in a bulk composite form having dimensions greater than 25 millimeters in each of the x, y and z directions thereof.

  • Patent number: 6500487
    Abstract: Apparatus and method for abatement of effluent from multi-component metal oxides deposited by CVD processes using metal source reagent liquid solutions which comprise at least one metal coordination complex including a metal to which is coordinatively bound at least one ligand in a stable complex and a suitable solvent medium for that metal coordination complex e.g., a metalorganic chemical vapor deposition (MOCVD) process for forming barium strontium titanate (BST) thin films on substrates. The effluent is sorptively treated to remove precursor species and MOCVD process by-products from the effluent. An endpoint detector such as a quartz microbalance detector may be employed to detect incipient breakthrough conditions in the sorptive treatment unit.

  • Patent number: 6460541
    Abstract: An inflatable structure comprising an inflation compartment defining an enclosed interior volume and an anti-reflux valve having an outlet end positioned in the interior volume. The anti-reflux valve includes an elongate inflation passage including opposedly facing film layers that are bonded to one another at their edges to form an interior gas flow channel. The elongate inflation passage is bonded to the inflatable compartment to form an opening for introduction of gas into the passage, for inflation of the inflation compartment, and arranged so that upon termination of gas flow into the interior volume, after pressure in the interior volume has been raised above exterior pressure on the inflatable compartment, gas pressure in the interior volume collapses the opposedly facing film layers against one another to form a seal against the interior volume gas pressure and maintain the inflation compartment in an inflated state.

  • Patent number: 6443097
    Abstract: A high efficiency recirculating marine aquaculture process for producing fish at variable yield densities of up to 60 kg/meter3 of the aquaculture tank, including fish that spawn under short photoperiods such as gilthead seabream (Sparus aurata) as well as fish that spawn under long photoperiods such as striped bass (Morone saxatilis). The process involves broodstock conditioning, spawning/reproduction, larval growth, nursery, and adult grow-out operations. The process is characterized by high-rate growth at optimal process conditions requiring less than 10% daily water exchange, thereby enabling effluent waste from the system to be discharged to a municipal sewer after disinfection treatment, which in turn permits siting of the aquaculture process facility in urban/suburban locations where aquaculture processes have been previously infeasible.

  • Patent number: 6418673
    Abstract: A strong, lightweight structural system wherein curved structural elements are tangentially joined. Compressive forces are distributed in a near continuous manner throughout the matrix, and tensile forces are present primarily to brace, support and pre-stress the compression net. The system is scalable from molecular through architectural levels, and finds many applications in dome shaped and spherical structures. The structural system also provides a force interaction model that is applicable to a broad array of real and theoretical problems.

  • Patent number: 6408472
    Abstract: A fixing tool for temporarily holding a midsole and a shoetree in shoe industry includes a screw base and a screw body. The screw base is formed as a hollow hob screw with both an inner thread and an outer thread. The screw body further includes a screw holder and a screw. The screw has a flat round top portion with periphery notches and is pivoted at a center thereof to allow the top portion able to make a 90° rotation. The screw base is used to be screwed into a proper position at the bottom of the shoetree. The screw of the screw body is then engaged with the respective screw base through the midsole for temporarily fixing the midsole and the shoetree. The screw holder of the screw body can be pushed aside to contact with the midsole. Unlike the conventional nail-fixing, the fixing tool of the present invention can hold the midsole and the shoetree by only screwing the screw of the screw body into the screw base.

  • Patent number: 6386358
    Abstract: The present invention relates to a tablet package that contains a predetermined number of tablet(s) and a predetermined quantity of liquid. The liquid in such tablet package is stored within a reservoir and is seperated from the tablet(s). The tablet(s) in such package is stored within a sealed compartment located in a closure member (e.g. a screw cap), which functions to close the reservoir and retains the liquid within the reservoir prior to use of the tablet package. The sealed compartment for storing the tablet(s) preferably has a breakable sheet through which the tablet(s) can be ejected. More preferably, the container has separating means (e.g. a grill member) located between the breakable sheet and the reservoir to prevent the tablet(s) from entering the liquid.
