摘要： A casing hanger for hanging well casing and sealing the well pressure from the atmosphere. The casing hanger comprises a cooperating slip and slip bowl adapted to grip and retain the well casing when they abut a cooperating shoulder on the casing head whereupon the casing hanger will be in its operating position. A seal is adapted to be compressed when the casing hanger is moved downwardly and forms the seal when the casing hanger reaches its operating position. A manually adjustable bolt can increase or decrease the seal pressure without disturbing the well casing.

摘要： An engine shutdown valve comprises a substantially circular gate valve (25) movable about an axis between open and closed positions within a valve housing (16) mounted in an engine induction manifold. A gate lever (23) connects the gate valve (25) with the axis and a movement mechanism (43, 52) acts to move the lever between the two positions. A restraining mechanism (36, 37) holds the gate lever (23) and the gate valve (25) in the open position and a release mechanism (49, 55, 57) is operable to release the restraining mechanism (36, 37) when desired. The restraining, release and movement mechanisms are all located in a latch housing (17) which is located exteriorly of the valve housing (16) and the manifold.

摘要： A jar tool for use in a drill string for use in dislodging a drill bit or well-tools trapped in well bores. The tool comprises an outer housing adapted to move longitudinally with respect to an inner spline mandrell. A piston assembly is acted on by a piston actuator and hydraulic fluid restricts the movement of the piston assembly and, therefore, the movement of the mandrell relative to the housing while the piston assembly is within a narrower portion of a hydraulic cylinder. When the piston assembly reaches a larger diameter portion of the cylinder, the hydraulic fluid rushes past the piston assembly which allows a knocker connected to the spline mandrell to collide with the outer housing. A compression spring returns the piston assembly to its rest position abutting a shoulder on the outer housing. Provision is made for a valve to be inserted in the piston assembly so that the system can be temperature compensated and more desirable hydraulic fluids can be used.
摘要翻译： 用于钻柱中的用于移动钻头或井眼井的工具的罐工具。 所述工具包括适于相对于内花键筒纵向移动的外壳。 活塞组件由活塞致动器作用，并且液压流体限制活塞组件的运动，并因此限制活塞组件在液压缸的较窄部分内相对于壳体的移动。 当活塞组件到达气缸的较大直径部分时，液压流体冲过活塞组件，这允许连接到花键筒的门环与外壳碰撞。 压缩弹簧将活塞组件返回到与外壳体上的肩部邻接的其静止位置。 为阀门插入活塞组件做出了规定，使得系统可以进行温度补偿，并且可以使用更理想的液压流体。

摘要： A wellhead sealing system comprises a casing (12), a tubing spool (16) and a bushing (22) between the casing (12) and the tubing spool (16). A first recess (24) is provided in the bushing (22) and a first casing seal (23) is mounted therein to act between the bushing (22) and the casing (12). A second recess (26) is provided in the tubing spool (16) and a first bushing seal (25) is mounted therein to act between the tubing spool (16) and the bushing (22). The casing seal (23) has cylindrical inside (27) and outside (28) surfaces located generally at the inside and outside diameters of the seal (23). The cylindrical inside surface (27) is defined by a radially inwardly extending convex central protuberance (29) and opposed cylindrical flat surface areas (30) extending axially outwardly from the convex central protuberance (29) into first transition areas(31) extending to respective end surfaces (32). The cyc- lindrical outside surface (28) is defined by a circumferential centrally located groove (33) flanked by axially outwardly extending flexible retaining flanges (34) forming second transition areas between the cylindrical outside surface (28) and the end surfaces (32). Spring means (35) extend around the inside circumference of the seal and are located adjacent each of the first transition areas (31).
