  • Patent number: 8739901
    Abstract: A percussion adapter that is driven to generate a percussive axial motion on a wellbore structure. One percussion adapter includes a drive connection to mechanically convert rotational drive to axially directed percussive motion. Another percussion adapter employs a valve that creates back pressure causing axially directed percussive motion. A wellbore tubular connection transitions torque to resist back off when left hand or right hand torque is applied.

  • Patent number: 8641104
    Abstract: A latch device (14) includes a latch bolt (30) movable between a latching position and an unlatching position. A sleeve (775) is mounted to an outer side (13A) of a door (11) and operatively connected to an outer operational device (12). A clutch (575) is mounted to and jointly movable with the sleeve (775). An unlatching member (711) is operably connected to the latch bolt (30) and releasably engaged with the clutch (575). When the unlatching member (711) engages with the clutch (575), operation of a handle (502) of the outer operational device (12) retracts the latch bolt (30). When the unlatching member (711) disengages from the clutch (575), the latch bolt (30) remains in the latching position if the handle (502) is rotated.

  • Patent number: 8544903
    Abstract: A roseless trim for a mortise or tubular lock includes through bolts on a bolt circle of less than one inch (25.4 mm). Spindle hubs with a curved slot allow at least one of the through bolts to pass through the spindle hubs. A tubular lock embodiment uses arms with a cutout. The arms function as through bolts when screws attach the arms to mounting plates on opposite sides of the door. Each handle is attached to a corresponding handle base with a bushing. The handle base and small diameter bolt circle cooperate to provide the appearance that the handle extends directly into the door without a rose, escutcheon or any other attachment structure at the base of the handle.

  • Patent number: 8505987
    Abstract: A latch assembly includes a latch movable between released and restrained positions and a latch spring biasing toward the released position. A first lever is movable between open and closed positions, corresponding to the released and restrained positions, respectively. A first lever spring biases toward the closed position. A second lever is movable between unlocked and locked positions, corresponding to the first lever open and closed positions, respectively. A second lever spring biases toward the locked position. An active material based actuator selectively moves the second lever from the locked to unlocked position in response to an activation signal. A primary activation mechanism selectively produces the activation signal without a mechanical connection to the passenger compartment. An auxiliary activation mechanism does not rely on the vehicle power system. A key or portable energy storage device may cause the activation signal from the primary or auxiliary activation mechanism.

  • Patent number: 8500129
    Abstract: A slide ring seal for high circumferential velocities for sealing liquids with little or no electrical conductivity, such as low-salt feed water for feed water pumps including a pair of slide rings, one of which is rotationally fixed and the other of which rotates with a rotating component. The slide rings have interacting sliding surfaces which form a region loaded with the liquid to be sealed relative to a sealing gap. One ring is formed of material with satisfactory electrical conductivity and the other of low conductivity material. The seal is arranged in a dead-end circuit of a rotating component to be sealed and is connected to a cooling system. A metering device is provided in the circuit for introducing a substance as a function of a slide ring seal leak to maintain the electrical conductivity of the liquid between 3 and 500 ?S/cm.

  • Patent number: 8491022
    Abstract: The present invention relates to a sliding door latch having a locked and unlocked position for a sliding door having an open and closed position. The sliding door latch includes a handle assembly with a handle and a locking mechanism. The handle is a first position, wherein the locking mechanism is engaged and the sliding door latch is locked, to a second position, wherein the locking mechanism is disengaged and the sliding door latch is unlocked The locking mechanism may prevent the handle from moving from the second position to the first position when the sliding door is open. The handle is pivotable between the first position and the second position only when the door is closed. Resistance forces may prevent the handle from moving from the second position to the first position when the sliding door is closed without an application of force by a user.

  • Patent number: 8474537
    Abstract: A wellhead connector for connecting a riser or production tree to a wellhead of a subsea well utilizes a singular annular piston to lock the connector onto the wellhead. The wellhead connector includes a housing that contains dogs for engagement with the exterior of the wellhead housing. A cam ring is also included, which has an inner side for engaging the dogs and moving them inward into a locked position with the wellhead housing. The cam ring is of a reduced proportion relative to prior art. As such, the cam ring outer side is dimensioned to contact the inner side of the connector housing under load. Connecting rods connect the piston to the cam rings. As the piston moves downward, the cam ring also moves downward, forcing the dogs inward into a locked position. As the piston moves upward, the cam ring also moves upward, thereby unlocking the connector. A secondary annular piston is also provided to guarantee unlocking.

  • Patent number: 8474883
    Abstract: A latching system for and a method of latching a first member to a second member are provided. The latching system includes a latching mechanism including a displaceable feature which, when operatively displaced, allows a striker to engage with a housing of the latching mechanism, at a recess defined by the housing, to provide supplementary or auxiliary latching force. The displaceable feature may be displaced by an actuating load transmitted between the striker and the latching mechanism, where the actuating load is substantially greater than the nominal load experienced by the latching system during ordinary latching conditions. The engagement of the striker with the housing at the recess may transfer a portion of the actuating load to the housing during the event generating the actuating load, thereby increasing the latching strength of the latching system and reducing the potential for deformation or distortion of the latching element during the event.
