    摘要: A compressor station having at least one primary compressor and a booster compressor is controlled to conserve energy and air, and to respond quickly to sudden changes in demand for air, by employing a volume bottle to buffer changes in air pressure and by recycling already compressed air from the intake to the output of the booster compressor. The system may be used in air drilling and to provide compressed air for generating low density drilling fluid on site by injecting microbubbles into a base drilling fluid. Two different methods of generating microbubbles are illustrated. The primary and booster compressors are kept in a state of readiness during drill pipe connection time, providing for a rapid resumption of pressure and air flow after connection is completed. The system can utilize gases other than air.

    摘要: A substantially nonaqueous composition comprising a polyol and potassium formate is made by removing water from a mixture while heating. The polyol beneficially contains 3-50 hydroxyl groups and may be polyglycerin. The water removed may originate from a solution of one or more of the ingredients, from a condensation reaction of hydroxyl groups, and/or from an esterification reaction of hydroxyl groups on the polyol(s) and the formate groups. The composition is effective for treating shale formations in well drilling to reduce hydration and sloughing of the shale. If, in the course of treating shale formations, the polyol/potassium formate composition mixes with connate or other water, the water may be removed on returning the composition to the surface, and recycled.

    摘要: A fluid conditioning system designed to be installed between the well perforation and the intake of a pump used to effect artificial lift is used to filter and chemically treat production fluids. The fluid conditioning system is an apparatus that provides scale inhibitors and/or other chemical treatments into the production stream. In some embodiments, the fluid conditioning system may be a part of the production stream filter wherein the filtering material is comprised of a porous medium that contains and supports the treatment chemical. In other embodiments, the chemical treatment may be accomplished by the gradual dissolution of a solid phase chemical. The treating chemical may be recharged or replenished by various downhole reservoirs or feeding means. In yet other embodiments, the treating chemical may be replenished from the surface by means of a capillary tube. In certain other embodiments, the apparatus may be retrievable from the surface thereby permitting recharge or replenishment of the chemical in the apparatus on an as-needed basis. The filtration apparatus may incorporate a bypass valve that allows fluid to by-pass the filter as sand or other particulate matter fills up or blocks the filter.

    摘要: Aqueous fluids are heated or boiled in a tank or vessel by causing cavitation in the fluid within the tank or vessel. A rotor having cavities on its cylindrical surface is rotated within a closely dimensioned housing submerged in the fluid, deliberately causing cavitation which heats the aqueous fluid without the use of flame or heat exchange surface. An electric motor which powers the rotor may itself be submerged in the tank or boiler vessel. The rotor includes radial channels for imparting centrifugal impetus to the fluid as it flows toward the cavitation zone.

    摘要: An OTC surgical device includes a handle having therein a compression controller and thereat an end effector, which has an electrically controlled tissue-compressor coupled to the controller and powered thereby to selectively control tissue compression. A mechanical binary-output electrical switch is disposed in-line with the compressor to place a compressing force directed upon the compressed tissue proportionally upon the switch. The switch has two switching states initiated and changed only by mechanical movement. The switch includes a biasing device retaining the switch in a first switching state until a force imparted thereupon overcomes the bias force to change to the second switching state. A switching-state-status output provides information identifying a current state and communicates with the compression controller to selectively control compression of tissue based upon the information. With appropriate feedback, the controller can keep the tissue at OTC while the surgical procedure is carried out.

    摘要: A flexible endoscopic dip applier includes a flexible coil with a manual actuator coupled to one end and a jaw assembly coupled to the other end. A store of clips is arranged adjacent to the jaw assembly and a clip pusher is arranged adjacent to the store of clips. The actuator includes a lever for opening and closing the jaws, a knob for rotating the jaw assembly, and a crank for dispensing clips. The knob and the lever are coupled to a single control member which extends through the coil to a joiner where it is joined to a pair of pull wires coupled to the jaws. The crank is coupled to a second control member which is threaded along a distal portion. The threaded portion engages a threaded member near the pusher and is coupled to the pusher such that rotation of the threaded control member by the crank causes the pusher to be moved distally.
