20090302243 | WIPER SEAL ASSEMBLY - A hydraulically-operated annular blowout preventer, for controlling a wellbore and comprising a wiper seal assembly, is described. The wiper seal assembly comprises a discrete wiper seal, for preventing debris and/or contaminants from the wellbore from entering the hydraulic fluid chamber of the blowout preventer, a discrete pressure seal, positioned below and abutting the wiper seal in the same seal groove, for isolating the hydraulic chamber, and a retainer member for preventing both radial and axial movement of the wiper seal. | 12-10-2009 |
20110030805 | BLOWOUT PREVENTER WITH LOCK - A lock for a ram shaft of a blowout preventer has a ram shaft controlled by an actuator, the ram shaft having a ram block end and a locking end, the locking end having an internal cavity that extends along an axis of the ram shaft, and a locking pin in the internal cavity. The locking pin has a release position retracted into the internal cavity, and a locking position extending from the internal cavity. A rotational stop engages the ram shaft and prevents the ram shaft from rotating. A locking pin stop is secured relative to the actuator, the locking pin stop engaging the locking pin in the locking position to prevent axial movement of the ram shaft. | 02-10-2011 |
20110031421 | BLOWOUT PREVENTER HAVING WEAR, SEAL AND GUIDE PLATE INSERTS - A method of preventing wear in a blowout preventer includes the steps of forming an inner surface of a blowout preventer body to receive wear inserts at least one wear point in the blowout preventer body; and securing at least one wear insert on the formed inner surface of the blowout preventer body. | 02-10-2011 |
20110031700 | SEAL ASSEMBLY FOR A PRESSURE PLATE IN A BLOWOUT PREVENTER - A seal assembly for a sealing a pressure plate against an opening in a blowout preventer body, has a seal groove formed in the pressure plate and a seal in the seal groove. The seal groove has a first groove portion adjacent to a sealing face of the blowout preventer, and a second groove portion extending past the sealing face into the opening of the blowout preventer body. The seal has a first seal portion in the first groove portion and a second seal portion in a second groove portion. | 02-10-2011 |
20120275736 | BEARING ASSEMBLY - A bearing assembly has a bearing chamber, an inner mandrel having a first load bearing shoulder and an outer housing having an second load bearing shoulder. The first and second load bearing shoulders are opposed and are within the bearing chamber. Seals retain a bearing lubricant within the bearing chamber. A cylindrical stack of bearings are positioned between the first and second load bearing shoulders. Each row of bearings has an inner race supporting the first load bearing shoulder and an outer race supporting the second load bearing shoulder. The bearing assembly may be incorporated into a downhole tool. The downhole tool may continue to be operated after the seals fail by flowing a working fluid through the bearings. | 11-01-2012 |

20130288810 | Universal Joint for a Downhole Drilling Motor - A universal joint carried by an elongate body having an axis. The universal joint has an inner race that pivots omni-directionally within an outer race and a series of first and second opposed cavities formed in the inner race and the outer race. There are a plurality of torque transfer elements, each torque transfer element having a first portion that engages a first cavity and a second portion that engages a corresponding second cavity. The first cavity is a socket that permits rotation of the first portion within the first cavity as the inner race pivots omni-directionally within the outer race and the second cavity is a track oriented in the direction of the axis of the elongate body. The second portion moves along the track as the inner race pivots omni-directionally within the outer race of the second portion along the track. The second portion has at least one drive surface that engages an inner surface of the track at more than one point along the direction of the track. | 10-31-2013 |
