Abstract: An inline pipeline expansion joint is provided having a first sleeve with the outer end adaptable to attach to a pipe. A second sleeve also has an outer end adaptable to attach the attachment of a pipe, the inner end of the first sleeve being co-axially and telescopically received within the second sleeve. A seal is interposed between the interior of the first sleeve and the exterior of the second sleeve. A tubular liner is positioned within the second sleeve, one end of the liner being telescopically received within the interior of the first sleeve to thereby reduce turbulence of fluid flow through the expansion joint. The first sleeve has an external annular circumferential flange with openings therethrough that receive circumferentially spaced alignment rods that are secured at one end to the second sleeve so that as the first sleeve moves telescopically with respect to the second sleeve, the two sleeves are prevented from rotating with respect to each other.

Abstract: A device suitable for holding a collapsible tube and dispensing the contents thereof is provided. The device has a base which supports and holds the tube, an upper plate pivotally attached to the base and adapted to pivot or rotate one or more times towards said base to compress the collapsible tube and dispense the contents thereof. The device also includes a forward wall having a vertically disposed slot which receives the neck of the collapsible tube and allows the tube to slide vertically as the tube is compressed and the contents are dispensed. Repeated rotations of the upper plate results in a milking of the contents of the tube and thus a controlled dispensing of the contents.

Abstract: A flow control valve 30 between a geothermal wellhead and a steam separator 22 is responsive to fluid pressure flowing through the wellhead to the separator and varies the flow rate to the separator 22 in response to the pressure to equalize the flow to the separator 22. A Y-type expansion spool 14 on the wellhead has a pair of auxiliary inlets 76, 78. One of the auxiliary inlets 76 has an auxiliary hanger 88 therein to suspend flexible tubing 94 for the injection of chemicals into the well and the other auxiliary inlet 78 provides an entrance 122 for taking a steam sample and permitting a tool to be inserted within the well.
