Abstract: A method of reducing hydraulic shock in a BOP system including a pressure regulator having an input port and an output port, and a regulator piston that moves between an open and a closed position based on a change in hydraulic pressure applied to the regulator piston via a pilot port. The method includes initiating a function, and monitoring the state of the function as it is carried out to predict when the function nears the end of its cycle. The method also includes, when the function reaches a predetermined state, adjusting the hydraulic pressure on the regulator piston via the pilot port to gradually move the regulator piston between the open to the closed position to reduce fluid flow through the fluid path in a controlled manner to reduce hydraulic shock.

Abstract: An expansion system is assembled by coupling a piston assembly and a solid cone assembly to an adjustable cone assembly within an expandable tubular having inner sleeve disposed in a portion thereof. The expansion system is run into a wellbore. The piston assembly is activated to move the solid cone assembly downward through the inner sleeve so as to expand the inner sleeve and the portion of the expandable tubular having the inner sleeve. The adjustable cone assembly is shifted from a retracted position to an expansion position within the inner sleeve. The adjustable cone assembly is moved upward through expandable tubular while leaving the solid cone assembly and the inner sleeve coupled to expandable tubular. The solid cone assembly and the inner sleeve may be drilled or milled.

Abstract: Provided are spacers, ion-exchange devices comprising spacers, and methods of preparing spacers for improved fluid distribution and sealing throughout an ion-exchange device. These spacers can include an internal cavity surrounded by a perimeter of the spacer. The perimeter can have a first opening and a second opening within the perimeter, and the first opening and the second opening can be located on opposite sides of the internal cavity. The spacers can also have a first and second plurality of channels located within the perimeter, wherein each channel of the first and second plurality of channels extends from the internal cavity towards the first opening or the second opening.

Abstract: The present disclosure is directed to ion-exchange systems and devices that can monitor key parameters related to the performance of the ion-exchange device. Specifically, the ion-exchange systems and devices disclosed herein can provide real time voltage drop across groups of membrane pairs using diagnostic spacer borders between the pairs.

Abstract: The present invention discloses an apparatus and a method to desalinate aqueous solution. The apparatus disclosed herein comprises at least two electrodes and at least one ion selective membrane in continuous contact with the aqueous solution that is contained in the internal space created by connecting a top manifold and a bottom manifold of the apparatus. The ion selective membrane(s) are arranged in such a manner as to enable reversing the flow of the charged particles by direct or indirect means. The electrodes in this apparatus may be made of material that reversibly reacts with chlorides in water.

Abstract: An asymmetric mold core and method for use for forming curved floor openings in pallets is taught. The mold core contains: a base, the base attachable to a frame in a rotomold, a bottom section integral at a distal end to the base, and a top section integral at a distal end to the base. Both the top section and the bottom section have convex radial curve shape, but the top section curve and the bottom section curve are positioned by having different centers of rotation so when the core is actuated it is only actuated around the center of rotation about the bottom curve which causes the top cure to drop away from the upper molded surface.

Abstract: An expandable sleeve is used for providing support to an obturation member. The expandable sleeve and the obturation member form a hydraulic isolation in a casing. The expandable sleeve has preferably a small thickness or cross-section, which can allow for a large flow-through inner diameter after expansion. Also, the expandable sleeve is preferably short. Thus, mill-up operations that are performed when the expandable sleeve is no longer in use can be expedited or even eliminated in some cases.
