Abstract: A header with associated lubricator is for fluid handling at the wellhead of an oil and gas well where a plunger/lubricator lift system is deployed, and provides a novel compact lubricator with attached header which can replace a conventional wellhead flow-tee without modifying or moving other wellhead equipment to accommodate the new lubricator and header replacing the old flow-tee. A sub seal is provided at the header/lubricator attachment(s). The header with associated lubricator encloses a conduit with seals in the attachment interfaces between the header and lubricator or between the header and exit attachment means, where the conduit may also comprise a means of flow restriction through machined geometry or by retaining a reduced diameter or valve component through various means of attachment. The flow restrictor means may also be serviced via service access means provided in the header or lubricator exterior wall.

Abstract: A check valve comprising a body, a ball movable within a ball area of the body, a seat for receiving the ball, and a magnet for exerting a magnetic force on the ball is provided. The ball and seat are changeable between a closed state and an open state, the closed state having the ball in sealing engagement with the step, and the open state having a portion of the step separated from the ball with a space therebetween.

Abstract: A plunger with expandable mating pad elements arrayed circumferentially about the plunger's body sealed to the plunger and biased to expand the plunger assembly's outer circumferential surface toward the inner surface of the tubular within which the plunger assembly is designed to operate. The gaps between the pad elements are minimized by having the adjacent pad elements slidable against each other along two sets of surfaces along essentially the length of the interface between adjacent pad elements, one surface set being approximately axial to the plunger and the other set being approximately radial to the plunger's longitudinal axis, and in this way reducing the available pathway in the gap between adjacent pad elements for fluid to bypass the plunger assembly.

Abstract: A catastrophic or heavy-hit indicator subassembly is included in a plunger lift system lubricator which includes a coil spring above a striker block, a piston above the striker block, the piston sealed but moveable within the bore of the subassembly, above the piston another spring or set of spring washers, a space, and above the space a thin membrane or wall in a top nut or seal at the top of the lubricator. If the plunger reaches the lubricator with sufficient force, it will compress the coil spring and move the striker block to push the piston upward within the bore of the lubricator, the piston will compress the second spring or set of spring washers, and the top end of the piston, which is preferably pointed, will pierce the membrane or wall in the top of the lubricator.

Abstract: A subassembly is provided which is designed so that two passageways in concentrically arranged tubing strings can be formed to provide a flow-path which in a first direction communicates with equipment at surface in an annular passageway then switches partway along the tubing strings' length in the well to the subassembly and is redirected to the core passageway, and back from the string's lower end up the annular space to the subassembly and is again redirected this time to the tubing's core passageway back to surface equipment; the two passageways being: the core passageway formed of the core tubing's inner volume; and the annular passageway formed of the annular space between the core tubing string and a concentrically surrounding second tubing string's inner surface; the subassembly forming a two-way cross-over between the two passageways at the same part of the string.

Abstract: An improved plunger with expandable mating pad elements arrayed circumferentially about the plunger's body sealed to the plunger and biased to expand the plunger assembly's outer circumferential surface toward the inner surface of the tubular within which the plunger assembly is designed to operate. The gaps between the pad elements are minimized by having the adjacent pad elements slidable against each other along two sets of surfaces along essentially the length of the interface between adjacent pad elements, one surface set being approximately axial to the plunger and the other set being approximately radial to the plunger's longitudinal axis, and in this way reducing the available pathway in the gap between adjacent pad elements for fluid to bypass the plunger assembly.

Abstract: The present invention is directed to a high density electrical connector which can provide 80 or more twinax connections per linear inch in a 20 millimeter card slot. In a typical electronic system package, 20 millimeters is the spacing from center line to center line of the adjacent parallel daughtercards. Twinax cable is coaxial cable that contains two .inner conducting wires rather than one. The two inner conducting wires provide two physical channels. Coaxial cable is called “coaxial” because it includes one physical channel that carries the signal surrounded (after a layer of insulation) by another concentric physical channel, both running along the same axis. The outer channel serves as ground.

Abstract: The invention relates to an electrical connector that can be used to electrically connect a daughtercard to a backplane.

Abstract: An interconnection system includes spacers arranged adjacent each other in a row, the spacers having cable sections disposed therein. Each cable section has at least one center conductor and an outer conductive shield. All of the cable sections have one end exposed on a first plane and a second end exposed on a second plane. Electrically conductive contacts are disposed within apertures in a pair of interposers so as to have one end making electrical contact with one of the cable sections and another end extending through its respective aperture in its respective interposer.
