  • Publication number: 20200350084
    Abstract: In a pressurized water reactor (PWR), emergency core cooling (ECC) responds to depressurization due to a vessel penetration break at the top of the pressure vessel by draining water from a body of water through an injection line into the pressure vessel. A barrier operates concurrently with the ECC to suppress flow of liquid water from the pressure vessel out the vessel penetration break. The barrier may comprise one or more of: (1) an injection line extension passing through the central riser to drain water into the central riser; (2) openings in a lower portion of a central riser to shunt some upward flow from the central riser into a lower portion of the downcomer annulus; and (3) a surge line providing fluid communication between a pressurizer volume at the top of the pressure vessel and the remainder of the pressure vessel which directs water outboard toward the downcomer annulus.

  • Publication number: 20200283172
    Abstract: An assembly for deployment and retraction of a panel for outer space environment usage, includes a member secured to the panel with the member having an axis of rotation. Mass component connected to the panel, with panel wrapped about member with mass component positioned a first radial distance from the axis of rotation. Mass component has a mass per unit area greater than a mass per unit area of the panel adjacent to the mass component. With a rate of rotation of the mass component and member being same, the mass component rotates about the axis of rotation at a second radial distance from the axis of rotation, wherein the second radial distance is greater in dimension than the first radial distance. With a rate of rotation of the mass component and the member changed to be different, radial distance of the mass component to the axis of rotation decreases.

  • Publication number: 20200179652
    Abstract: Devices, systems, and methods for articulating elongate flexible structures such as catheters optionally include an array of fluid-expandable bodies such as balloons. The array can be formed using separate strings of balloons formed along single-lumen balloon tube material. The balloon strings can be twisted together to form a multi-channel bundle, or the balloon strings may be circumferentially separated, each extending axially. Regardless, the balloons along a common lumen may be aligned so as to bend the catheter in a desired lateral direction. The fluid-expandable bodies may include an elastomeric bladder with a fiber braid so that inflation of the bladder shortens the assembly and applies axial tension to articulate the catheter. The elongate flexible structures may be pre-biased so as to form a bend when in a relaxed configuration, with the structures being articulatable from the bend.

  • Publication number: 20200025465
    Abstract: A plate for a heat exchanger has a longitudinal centerline, a reference plane parallel to the longitudinal centerline, and multiple corrugations provided in the plate that define flow channels through which fluid flows. The corrugations extend at an angle to the reference plane and at least some of the corrugations are intersected by the reference plane, wherein over at least a portion of a surface area of the plate the corrugations are arranged in sub-regions that have a longitudinal length and the corrugations of each sub region are at the same angle relative to the longitudinal centerline, and the corrugations of adjacent sub-regions are at different angles from each other, and wherein the corrugations in adjacent sub-regions meet at junctions and the junctions are not longitudinally aligned.

  • Publication number: 20200003345
    Abstract: A subassembly for a conduit fitting includes a first ferrule and a second ferrule alignable relative to an axis. The first ferrule includes a camming surface at a back portion thereof, and the second ferrule includes a surface that contacts the camming surface when the first ferrule and the second ferrule are axially moved together along the axis. A retaining structure retains the first ferrule and the second ferrule together as a subassembly, and includes a flange extending radially outward and axially rearward from the back portion of the first ferrule to define an outer diameter recess. The flange includes an end portion that extends radially inward to define an inner diameter recess retaining a forward portion of the second ferrule. The outer diameter recess and the inner diameter recess together define a hinge portion of the flange.

  • Patent number: 10279147
    Abstract: Articulation devices, such as comprising pull rings, are provided having improved or increased visibility under conventional visualization techniques, such as fluoroscopy. Such improved visibility is achieved by the presence of at least one insert comprised of a material that is more visible or detectable under imaging techniques than the pull ring. The at least one insert is positionable within a cut-out in the articulation device and fixed into place by a suitable method such as adhesive, soldering, swaging, welding, laser welding, etc. The insert resides within the dimensions of the walls of the pull ring so as to not increase the outer diameter or decrease the inner diameter of the pull ring. This maintains the profile of the overall articulation device.

  • Patent number: 7166125
    Abstract: An intraluminal grafting system having a delivery catheter comprising a flexible elongate tubular member having proximal and distal extremities and a capsule mounted on the distal extremity of the tubular member and including a graft disposed within the capsule. The graft is comprised of a tubular body configured to be secured to a blood vessel by a self expanding attachment system. The attachment system comprises a generally sinusoidal wire frame having apices which extend longitudinally outward from the end of the tubular body apices which are secured within the tubular body. Both the protruding apices and the base apices are formed with helices which bias the attachment system radially outward. The attachment system further includes a plurality of lumen piercing members that are oriented in a responsive relationship to the radially outward bias of the attachment system.

  • Publication number: 20030090083
    Abstract: A removable supplementary hitch pivots into operational position on a trailer tongue in concert with a primary trailer hitch of the dependent vehicle used in pulling the trailer. The secondary hitch includes at least one additional hitch between the trailing vehicle and the dependent vehicle. Another additional hitch is also commonly provided resulting in an additional hitch on either side of the primary hitch. To introduce a measure of tolerance to breaking the connection through unwanted turning of the power vehicle after the secondary hitch is attached between the vehicles, the connection between the bar and the channel may comprise a flexible spring connection that allows the bar to move off parallel to the channel in absorbing unwanted turning forces while biasing the bar to return to its parallel position.
