Abstract: THE ABSTRACT       A safety valve which interrupts fluid flow when it is substantially tilted or inverted, comprises a valve chamber with three lobes two of which have an inlet and an outlet opening at an inlet and an outlet valve seat, respec-tively.  A ball is freely movable within the chamber.  When the chamber is in its normal position, or preferred orienta-tion, the ball rests or floats in the third lobe, but when the chamber is tilted or inverted, the ball moves  into one of the other lobes and abuts against the inlet or the outlet valve seat.

Abstract: MEASURING OIL AND WATER CUTS IN A MULTIPHASE FLOWSTREAM WITH ELIMINATION OF THE EFFECTS OF GAS IN DETERMINING THE LIQUID CUTS (Texaco Docket No. D#76,53-F) In a pipeline or container at any of various petroleum producing operations, a multiphase fluid flowstream containing oil, water and gas is bombarded with neutrons and high energy gamma rays resulting from capture of thermal neutrons are detected.  The spectra of the detected gamma rays are then analyzed to determine the ratio of the gamma ray counts of the element sulfur to the element chlorine. From this ratio, the oil and water cuts of the fluid may be measured while eliminating the effects of gas in the flowstream on the measurements.

Abstract: TRANSDUCER SUSPENSION MOUNT APPARATUS                     Abstract A magnetic head/arm assembly has a suspension for an air bearing head slider that includes a single piece substantially rectangular flexure with two parallel flexible narrow fingers, a relatively stiff cross leg, and a central finger to which the slider is attached.          A combined load beam-spring element is formed from a single piece and is fastened to the flexure so as to engage a load protuberance formed with the central finger.          The substantially triangular load beam/spring element has flanges formed along a portion of its length to con-centrate the resilient spring action at the opposite end to the flexure while providing a stiffening action along the remaining portion of its length.  The stiff cross leg section of the rectangular flexure is crimped to detent the central finger to keep the attached slider parallel while allowing for the load protuberance thick-ness to the load beam.

Abstract: ABSTRACT OF THE DISCLOSURE       Amine molybdates are formed by reacting molybdenum trioxide (MoO3) with an amine in an aqueous medium essentially free of acid and in which is dis-solved a water-soluble ammonium or monovalent metal or divalent metal or trivalent rare earth metal salt of an acid, or a combination thereof.  Although the reaction may be carried out at room temperature, the reaction mixture desirably is heated to between about 75°C to 110°C. and preferably is refluxed to reduce the time required for completion of the reaction.  The reaction slurry is stirred while the reaction is occurring. Upon completion of the reaction, the amine molybdate is separated from the liquid phase, and is washed and dried.  After removal of the solid amine molybdate from the slurry the liquid component can be reused avoiding possible environmental difficulties.

Abstract: ABSTRACT   9961           A method for treating oil-contaminated drill cuttings at an onsite location, e.g. offshore drillsite, so that the cuttings can be disposed of directly without the risk of pollution. The contaminated cuttings are separated from the drilling mud and are mixed with an oil absorbent material which absorbs the free oil from the contaminated cuttings. A surfactant may be added to aid in binding the oil in the cuttings and the oil absorbent material. When the cuttings are of large size, they are preferably ground before mixing them with the oil absorbent material. When the mixture of cuttings includes small or dust-like particles, the mixture is compacted into pellets, briquettes or other masses having a sufficient density to sink in water.

Abstract: SHEAR THICKENING WELL CONTROL FLUID (C-666) ABSTRACT OF THE DISCLOSURE           The instant invention is directed to shear thicken-ing fluids which comprise a water swellable material (e.g., clay), capable of rapidly forming a paste having a strength of at least 2000 lbs/100 ft2 with the aqueous  solution employed and present in sufficient concentration to form such a paste a nonaqueous hydrophobic material comprising a hydrocarbon material and a surfactant and/or strengthening agent, and an aqueous solution comprising water and a water swellable/ water solution polymer, wherein the clay and water-polymer solution are kept separated by an intervening hydrocarbon-surfactant phase.  Preferably, the hydrocarbon-surfactant phase (oil phase) encapsulated clay is suspended in a con-tinuous phase comprising the water-polymer phase; however, suspension of clay and separate, discrete water-polymer droplet in a continuous oil phase are also possible as are compositions commonly called "double emulsions" as well as systems which are bicontinuous.  The intervening oil phase prevents the interaction between the water-polymer and the clay phases and results in a stable, non-reacting, pumpable composite, until such time as the oil barrier is ruptured by deliberate application of a sufficiently high shear force. Upon such rupture, the materials mix and interact resulting in a semi-rigid high strength paste.           Various well control problems such as oil and gas well blowouts can be controlled by use of the above-described composite.  The composite is pumped down the well pipe. Upon application of a sufficiently high shear as by exiting the orifices of the drill bit, needed to rupture the oil envelope. the clay and the water-polymer interact, resulting in the formation of the semi-rigid, high strength paste which cures the well control problem, sealing the well circulation thief zone or terminating or preventing a blowout.
