Abstract: Lower pipe stand racking combs are arranged to fold down from a side of the derrick at selected locations above the rig floor. In each racking comb an array of parallel fingers extend in a spaced array from a pivotable spine. The spine rotates to raise the fingers to a near vertical position to clear the rig floor activity area. A suspended pipe stand can pass laterally from the well center line past the ends of the fingers. The fingers, each, have a retractable extension that, when extended, will prevent the suspended pipe stand from passing the extended finger. The stopped pipe stand can then move transversely into the selected space between two fingers. Each finger extension has independent fluid power supply and control lines, the collection of the lines may extend to a control and power source selectively positioned on the rig floor or derrick. Raising of each comb assembly is, preferably, done by a fluid power cylinder attached to the derrick structure and to each comb assembly.

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.
