    摘要： A method for hierarchical layout of an electronic design using an electronic computer aided design system, wherein the method includes generating a parameterized pattern library and using an existing netlist and analyze in a pattern recognizer, from which a list of associations between the pattern library and the netlist is created. Renesting then occurs wherein the netlist using the list of associations is used for generating a hierarchical layout of the electronic components in the design.

    摘要： This invention pertains to improved formulations of platinum-molybdenum alloys for use as anode catalysts. These electrocatalysts find utility as a constituent of gas diffusion electrodes for use in fuel cells that operate at less than 180° C. or in applications whereupon hydrogen is oxidized in the presence of carbon monoxide or other platinum inhibiting substances. The new formulations derive unexpected activity through creating highly dispersed alloy particles of up to approximately 300 Å on carbon supports. The desired activity is achieved by carefully controlling the platinum to molybdenum ratio during preparation and judiciously selecting a proper loading of alloy on the carbon support.

    摘要： A method of reducing Ti(IV) to Ti(III) in which the Ti(IV) in acid solution is fed to an electrochemical cell having a semi-hydrophobic gas diffusion anode to which hydrogen gas is supplied. A current is passed through the cell to effect the electrochemical reduction and the Ti(III) is recovered for use as a re-attack solution in titanium dioxide pigment production or for use in indirect organic reductions. Ti(III) salts may also be recovered for use, for example, in the reduction of organic compounds.

    摘要： A carton bottom end tucker-tacker assembly for folding over, closing and tacking the bottom ends of a pair of cartons mounted on a pair of mandrels at a tucker-tacker station on a carton packaging machine. The tucker-tacker apparatus includes a tucker apparatus for engaging a pair of opposed triangular bottom end closure members on the bottom ends of each of a pair of stationary cartons and breaking the bottom end closure members and folding them inwardly toward a closed position, after which the tucker apparatus recedes and a pair of swingably mounted tucker and tacker jaws then move under the partially closed bottom end members of each of the pair of cartons and complete the folding and tucking operations, and concluding with a tacking in place of the bottom end closure tuck-over panel on each carton to retain the bottom end closure members in a square condition for subsequent transferral to a carton bottom end pressure sealing station. The tucker jaws and the tacker jaws are each water cooled, and they are adapted to be operated by the same power drive means as used to operate the tucker apparatus. The tucker-tacker apparatus comprises a pair of swingably mounted tucker wings, for each of said pair of cartons, which swing inwardly and outwardly in planes transverse to the direction of movement of the pair of cartons in and out of the tucker-tacker station. The tucker and tacker jaws of each pair of said jaws are pivotally mounted on an axis that is disposed transverse to the direction of movement of a pair of cartons in and out of the tucker-tacker station.
