  • Publication number: 20240344389
    Abstract: A battery-powered motorized window treatment for covering at least a portion of a window may be adjusted into a service position to allow for access to at least one battery that is powering the motorized window treatment. A headrail of the motorized window treatment may be adjusted to the service position to allow for easy replacement of the batteries without unmounting the headrail and without requiring tools. The motorized window treatment may comprise brackets having buttons that may be actuated to release the headrail from a locked position, such that the head rail may be rotated into the service position. The headrail easily rotates through a controlled movement into the service position, such that a user only needs one free hand available to move the motorized window treatment into the service position and change the batteries.

  • Patent number: 10087701
    Abstract: A system and method is provided for a low profile rotating control device (LP-RCD) and its housing mounted on or integral with an annular blowout preventer seal, casing, or other housing. The LP-RCD and LP-RCD housing can fit within a limited space available on drilling rigs. An embodiment allows a LP-RCD to be removably disposed with a LP-RCD housing by rotating a bearing assembly rotating plate. A sealing element may be removably disposed with the LP-RCD bearing assembly by rotating a seal retainer ring. Alternatively, a sealing element may be removably disposed with the LP-RCD bearing assembly with a seal support member threadedly attached with the LP-RCD bearing assembly. The seal support member may be locked in position with a seal locking ring removably attached with threads with the LP-RCD bearing assembly over the seal support member. Spaced apart accumulators may be disposed radially outward of the bearings in the bearing assembly to provide self lubrication to the bearings.

  • Patent number: 9567817
    Abstract: The exemplary embodiments relate to apparatus and methods for increasing the longevity of an RCD at a wellbore, including a bearing assembly configured for operating in the RCD. The bearing assembly is configured for reducing pressure proximate the bearing assembly including reducing pressure in a radial seal. Top and bottom seals are mounted against a wear sleeve adjacent to an inner member housed within the bearing assembly. The wear sleeve is configured to be sealed by the top seal and the bottom seal as the inner member rotates in the RCD. A pressure reduction system mounted with the RCD is configured to apply pressure via a wellbore pressure between the top seal and the bottom seal, which is lower relative to a pressure above the top seal, and which is higher relative to a pressure below the bottom seal.
