  • Patent number: 4345735
    Abstract: An oil well blowout preventer includes a radially compressible annular packing having radially-sectored end portions in a housing having axially aligned upper and lower bores communicating with the inner bore of the packing and with the sectored ends, and also includes hydraulic means for radially constricting the packing, thereby causing it to axially expand. A plurality of circumferentially-arranged rigid wedge members carried by the sectored end portions are individually movable radially into the bores to control the axial expansion whereby radial sectors of the packing may move sequentially inward to effect a seal between the upper and lower bores in response to progressive axial expansion of the packing as the packing undergoes nonuniform sector-wise radial compression. The inward radial movement of the rigid members are limited by stops to a common radial position independent of the uniformity of the radial compression.

  • Patent number: 4345736
    Abstract: A dashpot assembly has a movable cylindrical element mounted within a housing. The movable element has a chamber with a first opening for restricting flow of fluid into the chamber and a second opening for permitting rapid flow of fluid out of the chamber. An enlarged head is disposed inside the chamber and is coupled to a poppet with a spring coupled between the poppet and the movable element. When the poppet moves in a direction away from the movable element, the enlarged head closes the second opening and pulls the element. Fluid then flows into the chamber only through the restricted first opening, thereby damping the rate of movement of the poppet. When the poppet moves in a direction toward the movable element, the enlarged head opens the second opening and the spring is effective to move the element in the same direction; fluid flows unrestricted through the second opening, thereby permitting an undamped movement of the poppet.

  • Patent number: 4345742
    Abstract: A hydraulic yarding system in which the haulback and main drum are coupled to a primary drive motor and provided with a hydraulic interlock motor coupled to a planetary set in the haulback drive in an open loop hydraulic circuit. The hydraulic fluid from the interlock motor can be diverted to the hydraulic circuit for the primary drive motor through a pressure sequence valve and a directional valve. In this manner, regenerative driving of the interlock motor by the load pumps fluid from the interlock circuit selectively in the desired direction to the primary drive motor and supplements the power available to the primary drive motor. A preferred embodiment utilizes two pressure sequence valves in circuits to either the in-haul or out-haul fluid flow directions for the primary drive motor so that a diversion of fluid from the interlock circuit can occur at a lower pressure valve during out-haul.
