摘要： A hydraulic casing hanger and packoff installation tool includes a central tubular member with a drill pipe upper connection and an annular chamber at the lower end thereof with a pair of concentric axially movable pistons mounted therein. A plurality of fluid passages are positioned in the wall of the tubular member and extend from the piston annular chamber to the middle portion of the tubular member where it exits. The pistons have a lower tubular extension which carries releasable latching mechanism which connects the tool to the packoff to be installed and transmits the axial force of the pistons to the packoff. A drill pipe stinger extends through the annular chamber with a releasable latching mechanism mounted on an enlarged lower portion. The releasable latching mechanism connects the tool to the casing hanger for lowering the casing and hanger into the well bore.

摘要： An unsoldering iron has a heated unsoldering bit with a bore that communicates by means of a suction tube with the front end of an elongated tin collecting container, the rear end of which is linked by a suction tube with a vacuum source. The front end (7) of the tin collecting container (6) is conical and the suction tube (8) extends into the container through a bore (9) in the envelope of the conical end of the tin collecting container (6), projecting beyond the inner wall of the envelope over considerable distance, so that a tin collecting space is formed around the part (5) of the suction tube (8) that projects inside the conical end (7).

摘要： A gate valve includes a gate cavity (18), a flowbore (14, 16) communicating with the gate cavity and a gate (20) for opening and closing flow through the flowbore. A valve seat (42) is provided on each side of the gate. Each valve seat (42) has inner and outer C-ring seals (52, 54) on its end surface for sealing against a body sealing surface (46). The seals are energised by an assembly which includes a disc spring (62) disposed around the valve seat (42).

摘要： A drapery support rod assembly including opposed support brackets for supporting the rod at a predetermined distance with respect to a vertical wall and giving the appearance of a continuous rod section extending from the wall at each end. Opposed elongated channel shaped bracket members, inner cover members and outer cover members are preassembled by a threaded fastener and secured to the rod section by tang portions of the bracket members for securing the bracket assemblies to the rod section. The bracket assemblies may be loosely secured, one part to the others and secured to the rod section and then assembled to the wall brackets by a push-on operation. The wall brackets include generally horizontally projecting arm portions with elongated slots formed therein for receiving the assembly of the channel shaped bracket member and the inner cover part. The outer cover parts may include extension members having an outer wall shape corresponding to the outer wall shape of the outer cover members to selectively extend the position of the rod section with respect to a wall surface.
