20150090462 | FLUID VENT ASSEMBLY AND METHOD OF VENTING FLUID - A housing for a downhole tool, having a fluid vent assembly comprising a port passing through the wall of the housing to transmit fluid through the port when the port is open, a sealing device to seal the port, and a cutting device to disrupt the sealing device and permit transmission of fluid through the port. The cutting device is driven axially through the sealing device without relative rotation between the two. The cutting device has an asymmetric blade to cut a coupon from the sealing device by a gradual and progressive disruption of the closure, typically cutting through only a portion the closure device, so that the coupon cut from the closure device remains attached to the closure device when the closure device is ruptured to open the seal. Typically the downhole tool comprises a downhole pump, and the housing comprises the shroud of the pump. | 04-02-2015 |
20110306227 | CONNECTOR - There is disclosed a connector, such as a wet-mateable connector, comprising first and second components having first and second contacts respectively and arranged to be coupled together such that the first and second contacts make a connection. The connector comprises a shuttle associated with the first component and moveable between at least a decoupled position in which the shuttle protects the first contact and a coupled position in which the first contact is exposed. During coupling of the first and second components the shuttle is moved to the coupled position so as to expose the first contact such that it can make an electrical connection with the second contact. The connector also comprises a latch arranged to latch the second component to the shuttle such that upon decoupling of the first and second components, the shuttle is returned to the decoupled position. | 12-15-2011 |
