    Abstract: A safety bead chain for blinds is revealed. An external member and a mounting member are disposed on two ends of the bead chain respectively. The external member consists of a groove and at least two first locking parts arranged around the groove. The mounting member is set with at least two second locking parts locked with the first locking parts correspondingly. Thus the external member and the mounting member are locked with each other to form a safety bead fastener bead with the same shape as a bead of the bead chain. The two ends of the bead chain are released from each other once a pulling force is applied to the bead chain to keep children from getting tangled in the bead chain. Moreover, the bead chain is moved around the clutch in a circular manner. Users can operate the bead chain more conveniently.

    Abstract: A slatted blind is configured such that the slats close create a light blocking blind. The slats may be supported by a tilt cord that comprises a low stretch strand or a low stretch cord may be attached to the tilt cord. The slats may be connected to the supporting tilt cord such that when the slat is rotated to a closed position the slat is suspended from the rung. The rung may have an effective diameter of less than approximately 14 mil. Recesses may be formed in the slat for receiving the rung when the slat is in a closed position. A bottom rail may have a thickness approximately equal to the thickness of the slats. A protrusion may be formed on the back of the slats such that the rung pushes on the protrusion to force the slat against an adjacent slat when the blind is closed.

A number of second permeable structures in fluid communication with the manifold are disposed adjacent a permeable (screen) section of the tubing. These second structures pass the carrier fluid from the manifold to the borehole annulus adjacent the screen section. In this way, the slurry in the blank section can be dehydrated for gravel packing by leaking of the carrier fluid to the screen section. The manifold and structures can also be beneficial in increasing the producible area of the tubing for production.

  • Publication number: 20170022792
    Abstract: The objective of the present invention is to provide a reclaiming machine for fluids in wells, which performs strokes on a cyclical basis up to the bottom of the casing pipe of the well, collecting fluids brought to the surface and drawing them from the well by gravity. The reclaiming basket is the component performing the downstroke towards the bottom of the casing pipe of the well, to submerge in the hydrocarbon to be collected, and then begin the upstroke with the hydrocarbon collected, stored at the top of the pickup basket, to draw it from the well by gravity through the unloading head. Included in an embodiment is a pickup basket having communication ports, a positive check valve, and a gear motor. When the upstroke concludes, the collected fluid is directed through an unloading coupling and stored in a unloading tank and directed where it is required.

    Abstract: A method for pumping fluid at a wellhead is provided. The invented method will improve liquid removal by eliminating the need to transport liquid produced from a well to containment facilities using trucks or large diameter pipelines capable of accommodating periodic surges of a high volume of fluid. The danger that the liquid will freeze in cold weather is also addressed. The invention removes liquid from the well site through a small diameter pipeline as a continuous flow at a constant flow rate. An apparatus for removing liquid from the well site is also provided.

    Abstract: Carbon quantum dots are used as tracers during the production of hydrocarbons. The tracer may be used to identify fluids produced from the reservoir. When used in the fracturing of multiple zones of the reservoir, qualitatively distinguishable carbon quantum dots may be used to identify the zone within the reservoir from which recovered fluid was produced. The carbon quantum dots may also be used in water flooding to determine water breakthrough in the production well. Upon water breakthrough in a production well, they may also be used to identify those injection wells from which breakthrough water originates.
