Abstract: ABSTRACT OF THE DISCLOSURE           Apparatus and method for skimming an overlying non-conductive lighter liquid from an underlying con-ductive heavier liquid in a two liquid body which are particularly  applicable  for  recovering  oil  and/or gasoline from a well.   A skimmer designed to float in the two-liquid body contained  in the well  includes a closed  cylindrical  float,  a  hollow cylindrical  skirt installed over a portion of one end of the float and permanently attached to the float.  The end of the skirt surrounding  the  float is open to the lighter  liquid. Spaced-apart liquid level controls are positioned on the skirt  for  sensing  the  liquid/liquid  interface  level. The other  end  of the skirt  is connected to a pump for  removing  lighter  liquids collected  in  the skirt. Means operated by the controls turn the pump off and on in response to higher and lower levels, respectively, of the two-liquid interface.

Abstract: FIBER OPTIC CABLE                ABSTRACT OF THE DISCLOSURE A fiber optic cable contains large diameter optical fibers for directly transmitting visible signals, such as those produced by water level indicators, within a steam boiler.  The fibers are each sheathed in an extruded layer of polymeric material that remains soft over an operable temperature range of the cable, and the sheathed fibers are cabled in a long lay length about an axial core member that has a coefficient of thermal expansion similar to that of the optical fibers in order to restrain the sheaths, which generally have significantly different thermal coefficients of thermal expansion, from excessively expanding or contracting relative to the fibers.  The cabled, sheathed fibers are wrapped in tape, and an inner jacket, which holds the sheathed fibers in compression, is extruded around the tape.  Tensile strength is provided by braided yarn surrounding the inner jacket, and crush strength is provided by an outer jacket surrounding the braided yarn.

Abstract: WELL LOGGING DATA ACQUISITION, TELEMETRY      AND CONTROL METHOD AND SYSTEM          ABSTRACT        A downhole microprocessor controller disposed in a well logging sonde receives and stores one or more preselected tables or series of logging tool commands down loaded from a surface computer through a logging cable telemetry link.  Each tool command in a particular table may correspond to a specific function to be performed by a respective logging tool comprising the sonde.  All such commands in a given table may be called up by the controller from memory in response to a corresponding sequence command from the surface computer associated with the desired table.  Upon receipt of such a sequence command, the microprocessor sequentially recalls each of the table's tool commands and relays them in order to the tools.  Each command has an address field and a command field, and each tool has a universal interface which decodes the fields whereby a particular tool may be selected by the address field and preselected functions from a plurality thereof may be performed by the tool in accordance with the command field word.  The number of tools activated, the order in which they are activated, the order in which functions are performed by a particular tool, and the number thereof are selectively variable and controllable by the software tables selected from the surface sequence commands.

The inwardly facing surface of the first conductor also serves as one electrode of a capacitor. Subsequently, the electrode electrically and mechanically contacts the inwardly facing surface of a second buss conductor.  Accordingly, the electrode and dielectric inner surface of the first conductor form a capacitor which is sandwiched between the two flat buss conductors.

Abstract: ABSTRACT      Sub-micron sized powders of the ceramic metal oxides such as zirconia, alumina, titania, etc. are produced by precipitation from substantially anhydrous solutions of salts of the corresponding metal(s) with substantially anhydrous solutions of alkali metal hydroxides.  The precipitates are subsequently washed with water to remove any residual soluble salt and/or solvent, then are dried and usually calcined.  The powders thus produced are readily sintered to high density ceramic bodies after conventional pressing into the desired shape.      The process is especially suited to the produc-tion of zirconia powders, either pure or doped with conventional stabilizing oxides such as yttria. In a typical example, a zirconia powder doped with 5.4% by weight of yttria is prepared by adding a solution of zirconium tetrachloride and yttrium chloride in anhy-drous ethanol to a solution of sodium hydroxide in anhydrous ethanol.  After washing, drying at 105°C, and calcining at 500°C for two hours, the powder is pressed at 5000 psi into a green body with a density of 1.46 Mg/m3.  After one hour of sintering at 1600°C, the fired body has a density of 5.84 Mg/m3, which is 96% of the theoretical maximum.

Abstract: Abstract Apparatus for reading a line marking The apparatus comprises a reading surface  which is formed by a plurality of photo-diodes.  Each photo-diode is connected to an input of an AND-gate.  The AND-gates each have another input which receives pulses from a scanner which distributes pulses to the inputs of the AND-gates in turn.  The AND-gates are actuated in turn and, if the associated photo-diode is illuminated by the image of a marking element passes a signal to a counter.  A decoder connected to the counter produces a signal indicating how many of the photo-diodes are illuminated and, thus, the length of the marking element.
