Abstract: A well depth measuring device that collects depth data so operators do not have to manually record the data in the field and then again into a computer. The well measuring device is attached to the well head. A rotary encoder rotates as a probe/sensor is lowered into the well via a longitudinal strip of tape. The rotary encoder sends pulses to electrical circuitry and a handheld computer that stores longitudinal information. The stored information can be easily transferred to other computers and databases.

Abstract: A solid oxide fuel cell comprises a dense electrolyte disposed between a porous anode and a porous cathode wherein the dense electrolyte comprises doped lanthanum gallate or yttria stabilized zirconia, the porous anode comprises yttrium-doped strontium titanate, yttrium-doped strontium titanate and nickel, lanthanum-doped ceria and nickel or yttria stabilized zirconia and nickel and the porous cathode comprises doped lanthanum ferrite or strontium-doped lanthanum manganite. The fuel cell may further comprise an interlayer(s) comprising lanthanum-doped ceria disposed between an electrode (anode, cathode or both) and the electrolyte. An interconnect layer comprising doped lanthanum chromate may be disposed between the anode of a first single fuel cell and the cathode of a second single fuel cell. The anode, cathode, electrolyte and optional interlayer(s) are produced by thermal spray.

Abstract: A sodium-sulfur battery is described which contains, in addition to a conventional sodium electrode, a conventional sulfur electrode and a conventional solid electrolyte, an additive which reduces the operating temperature of the cell without significant deleterious effects on operating characteristics.
