  • Patent number: 10371295
    Abstract: A pipe fitting has housing portions attached in spaced relation to define non-coaxial receptacles that receive pipe elements. The housing portions are supported on split rings received within grooves in each housing portion. The housing portions are supported in spaced relation in a preassembled state to permit insertion of pipe elements into the receptacles without disassembly of the fitting. The grooves in the housing portions have a floor surface with three surface portions. Two of the surface portions on each groove of each housing portion engage the split rings when the housing portions are supported in spaced relation.

  • Patent number: 9756715
    Abstract: A flange joint system for SRF cavities. The flange joint system includes a set of high force spring clamps that produce high force on the simple flanges of Superconducting Radio Frequency (SRF) cavities to squeeze conventional metallic seals. The system establishes the required vacuum and RF-tight seal with minimum particle contamination to the inside of the cavity assembly. The spring clamps are designed to stay within their elastic range while being forced open enough to mount over the flange pair. Upon release, the clamps have enough force to plastically deform metallic seal surfaces and continue to a new equilibrium sprung dimension where the flanges remain held against one another with enough preload such that normal handling will not break the seal.

  • Patent number: 9200860
    Abstract: A blast and projectile resistant gun port is provided with both a roller-slide mechanism and a lever-actuated, spring-loaded, cam mechanism which a shooter operates to open or close a gun-port door over a gun-port opening in a gun-port frame, as well as to translate the gun-port door out of the way of the gun-port opening. The shooter is able to effect these actions by nudging the lever on the cam mechanism with or without placing one or more hands on the lever and is thus able to keep both hands on weaponry. The gun-port door keys into its closed position, and an elastic weather seal is squeezed firmly between the gun-port door and the gun port frame when the gun-port door is closed. The squeezing of the weather seal is effected by springs in the cam mechanism. The gun-port door and the components and subassemblies are easily and rapidly replaceable.

  • Patent number: 8888144
    Abstract: Systems and methods for connecting misaligned pipe sections, where two sets of variably spaced bearings enable the transfer of evenly distributed pressure from a collar member to a coupling member. One embodiment comprises a misalignment coupling that includes first and second coupling members, a collar, and two sets of bearings. The collar is positioned around the second coupling member and has a flange for coupling to a flange of the first coupling member. The bearings are positioned in an annular space between the second coupling member and the collar. The two sets of bearings have variable spacing and are interleaved, with one set contacting the collar and one set contacting the second coupling member. When the flanges are secured to each other, contact pressure is transferred from the collar through the bearings to the second coupling member, thereby applying contact pressure between the first and second coupling members.

  • Patent number: 7976074
    Abstract: Sealing systems for high pressure applications that provide electrical isolation between joined elements as well as enhanced resistance to leakage of media during a fire. High pressure sealing is accomplished using a metallic core to which an electrically isolating material is bonded on either or both sides. Sealing is achieved through a dielectric sealing element, such as a spring-loaded polytetrafluoroethylene (PTFE) ring. Flanges of the joint may be bolted together with the seal interposed therebetween, and the flanges bolted together. In the event of a fire, heat may be generated that is at a high enough temperature to burn away the isolating material and PTFE ring. Systems of various embodiments provide a metal core backup seal and a compression limiter, which, respectively, prevent the media from leaking from the joint and maintain bolt load at the flanges.

  • Patent number: 7931310
    Abstract: A coupler for use with a sealing member for releasably securing together adjacent ends of grooved end pipe and forming a fluid-tight seal therebetween. The coupler includes a pair of arcuate segments, each segment having a generally inverted U-shaped cross-section so as to define a pair of depending leg portions and an outer spanning wall extending therebetween, each of the coupling segments further defining first and second end portions. The first end portions of each arcuate segment are joined together in a pivotal connection. A closure including a bail pivotally mounted on a release/locking lever, an attachment hook and a pair of abutment surfaces is provided at the second end portions of the arcuate segments for releasably joining and securing together the second end portions of the segments about the sealing gasket and adjacent pipe ends with the leg portions of the segments projecting into the grooves therein.

  • Patent number: 7914053
    Abstract: A flange connection has two pipe ends (1?, 2?, 51?, 52?) on each of which one flange (1, 2, 51, 52) is disposed and which have flange faces (11, 11?, 61, 61?) and a centering ring (33, 34) with an elastomer sealing ring (14) in contact with the ring. Both flanges include a mechanism for the detachable clamping against one another such that the flange faces (11, 11?, 61, 61?) are in contact on the centering ring and thereby are held at a predetermined flange distance (10, 60, D). The elastomer sealing ring (14) is pressed on the flange faces (11, 11?, 61, 61?) in the direction of the pipe axes (15) forming a seal, wherein the centering ring (33, 34) is positioned such that it is at least partially in contact on the periphery of the flanges (1, 2, 51, 52).

  • Publication number: 20100320756
    Abstract: A mechanical pipe coupling formed of segments attached end to end surrounding a central space is used to connect pipe elements having a raised circumferential shoulder in end to end relationship. The segments have arcuate surfaces and arcuate landings which subtend an angle less than 180° and which have a radius of curvature greater than the radius of curvature of outer surfaces of the pipe elements on the raised circumferential shoulder. The segments are maintained in spaced relation allowing the pipe elements to be inserted into the central space without disassembling the pipe coupling. Connection members attaching the segments to one another are tightened to engage the arcuate surfaces or the arcuate landings with outer surfaces of the pipe elements to effect the connection.

  • Patent number: 7828339
    Abstract: A coupling assembly is disclosed for joining pipe elements to one another end-to-end. First and second rings are attached to an end of each pipe element. Each ring has an outwardly facing surface with a groove which receives a sealing member. A band is positioned in overlying relation surrounding the rings when the pipe ends are arranged in end-to-end relationship. The band has an inwardly facing surface engaged with the sealing members. The band also has oppositely disposed end faces. End plates are attached to each end face. The end plates project radially inwardly in overlapping engagement with the rings to retain the pipe elements in end-to-end relation within the band.

  • Patent number: 7823265
    Abstract: An assembly for moving a pair of flowline members relative to each other has a pair of flowline collars that are adapted to connect to an end portion of one of the pair of flowline members. The assembly has an arm member with an end portion rotationally mounted to one of the flowline collars and a connecting member pivotally mounted to the other flowline collar. The connecting member is pivotally mounted to the arm member a distance away from the end portion of the arm member that is connected to the flowline collar, so that rotational movement of the arm member moves the flowline members relative to each other. The assembly can also have an incremental distance adjustor assembly which maintains an incremental change in the distance between the pair of flowline collars during a rotational movement of the arm member.
