  • Patent number: 6800158
    Abstract: A conductive co-fired body for an electrochemical cell for an exhaust sensor comprises zirconia, yttrium oxide, and alumina. The body comprises about 15 to about 30 weight % monoclinic phase zirconia. This produces an electrochemical cell having low impedance wherein the zirconia body and alumina body are co-fired. One method for manufacturing the electrochemical cell comprises combining zirconia, yttria, and alumina with solvent and dispersant to form a mixture. After, binder is added to the mixture which is then de-aired and cast onto a tape surface. The tape is dried, metallized, and laminated to an unfired alumina surface. The structure is then co-fired to form a body for said electrochemical cell.

  • Publication number: 20030129400
    Abstract: A dispersion of non-melt-processible fluoropolymer particles having an SSG of less than about 2.225 in aqueous medium. The fluoropolymer particles comprise a core of high molecular weight polytetrafluoroethylene having an average melt creep viscosity greater than about 1.5×1010 Pa·s and a shell of lower molecular weight polytetrafluoroethylene or modified polytetrafluoroethylene. The shell has an average melt creep viscosity greater than about 9×109 Pa·s and comprises about 5 to about 30% by weight of the particles. The fluoropolymer in the dispersion of the invention is fibrillating.

  • Publication number: 20030111232
    Abstract: A drilling rig derrick is adapted to direct the hoist lines reeved between the crown block and the traveling block such that they enter both in a vertical direction if the traveling block is moved laterally to clear the work area over the rotary table. Arrangements are provided to move the crown block laterally, and to move it back over the rotary table. Alternate provisions displace the reeved lines with idler sheaves to move the traveling block only and direct the reeved lines such that they enter both crown block and traveling block sheaves in a near vertical direction. Methods for both options are provided.
