摘要： A latch and method for use is provided for latching an item of oilfield equipment. The latch has a housing containing a latch member, and the latch member is movable between a radially engaged position in which it is engaged with the item of oilfield equipment, and a radially retracted position in which it is disengaged from the item of oilfield equipment. An actuator is configured to drive the latch member into the radially engaged position. Further, the actuator is configured to drive the latch member toward the radially retracted position.

摘要： A seal assembly for use with a rotating control head is provided. The seal assembly includes a rotatable member and a cavity formed between the rotatable member and a tubular radially inwardly disposed from the rotatable member. The cavity having a first surface and a second surface. The seal assembly further includes a seal member having a first end and a second end disposed between the first surface and the second surface of the cavity and sealable with the tubular between the first and the second ends due to deformation of the seal member.

摘要： Latch position indicator systems remotely determine whether a latch assembly is latched or unlatched. The latch assembly may be a single latch assembly or a dual latch assembly. An oilfield device may be positioned with the latch assembly. Non-contact (position), contact (on/off and/or position) and hydraulic (flowmeter), both direct and indirect, embodiments include fluid measurement systems, an electrical switch system, a mechanical valve system, and proximity sensor systems.

摘要： A hitch adapted to be mounted in the bed of a pickup truck for towing a trailer having a coupling mechanism and safety chains. The hitch includes a ball adapted to releasably interlock with the coupling mechanism. The ball has an upright position for engaging the coupling mechanism and a stowed position. The hitch further includes vertically oriented rings for engaging the safety chain. The rings are slidably located in horizontal slots in the hitch and are slidably retained in the slots by pins located transversely with respect to the slots. The rings are movable upwardly from stowed positions for engagement with the safety chains. The rings automatically drop to the stowed positions by virtue of gravity acting on the rings after the safety chains have been disengaged from the rings. The stowed positions of the ball and the rings insure that the bed of the pickup is substantially unobstructed by the presence of the hitch when the hitch is not in use.

摘要： A hitch adapted to be installed in the bed of a pickup truck and adapted to interlock with the kingpin of a fifth wheel trailer in order to couple the trailer to the truck. The hitch includes a pivoted latching plate for securing the kingpin, a reciprocating locking bolt for holding the latch in a latched position and a pivoted detent link for holding the locking bolt in an unlocked position when the trailer is uncoupled from the truck. When the trailer is subsequently re-coupled to the truck, the latch automatically trips the detent link to allow the locking bolt to shift automatically to a locked position holding the latch in a latched position.
