  • Publication number: 20260139763
    Abstract: Devices and methods for reducing vibrations. Methods include inserting a device for reducing vibrations within a pressure-control device, where the pressure-control device includes at least one movable element. The device for reducing vibrations includes a first body comprising a first material inserted adjacent to the at least one movable element and a second body comprising a second material, positioned radially opposite the first body. In one or more embodiments, the method also includes moving the at least one movable element of the pressure-control device and absorbing a portion of vibrations, introduced by moving the at least one movable element, using the device for reducing vibrations.

  • Patent number: 12631264
    Abstract: Systems, methods, and devices for magnetically actuating a gate valve of a subsea system via external magnetic actuation from a magnetic actuator. The magnetic actuator is disposed externally around a valve cavity such that motion of a valve stem disposed within the valve cavity can be controlled externally through magnetic coupling with the magnetic actuator such that a physical link (and the dynamic pressure seals associated therewith) is not needed to actuate the valve stem.

  • Publication number: 20260126123
    Abstract: A disclosed choke valve insert includes a cage, bonnet, valve stem, and seal assembly. The cage has an orifice configured to receive a flow of fluid. The bonnet is disposed superior to the cage and has a stem bore and cavity. The seal assembly is disposed within the cavity and around the stem bore. The seal assembly includes a seal housing, inner seal, and outer seal. The seal housing has an inner slot and outer slot. The inner seal is disposed within the inner slot and configured to prevent a portion of the flow of fluid from leaking superiorly past the inner seal. The outer seal is disposed within the outer slot and configured to allow the portion of the flow of fluid to return to the stem bore inferior to the inner seal when the inner seal fails.

  • Patent number: 12359540
    Abstract: Systems, methods, and devices for relieving overpressure associated with thermal expansion of fluid within a closed cavity of a subsea manifold assembly. The subsea manifold assembly may comprise a header bore fluidly connected to one or more branch connections. A unidirectional valve is included at the branch connections to allow fluid leakage from the closed cavity into a header bore of the subsea manifold assembly to thereby reduce a pressure within the cavity while in the closed position.

  • Patent number: 4540865
    Abstract: A keyboard (61) is provided with rubber (silicone) buttons (64, 66) with collapsible webs (14) connecting the buttons to a base layer (10, 40, 60). A solid finger of rubber (20) underneath each button actuates a membrane switch (23) underneath the button. Additionally or alternatively a conductive member (52) can be attached to the end of the finger (20) to make two contacts (48, 50, 56, 58). The buttons and the finger can be of any suitable section, such as round, rectangular etc., and a variety of types of membrane switches can be used.
