  • Patent number: 10502352
    Abstract: A joint assembly for connecting a first pipe having a first inner diameter and a second pipe having a second inner diameter which is larger than the first inner diameter comprises, an annular section comprising an annular wall defining a flow path through the annular section and configured to connect to the first pipe and the second pipe, and a clamp portion configured to clamp the second pipe between an outer surface of the annular section and an inner surface of the clamp portion. An inner diameter of the annular section varies from a first inner diameter at a first end of the annular section to a second inner diameter at a second end of the annular section. The first inner diameter is substantially equal to the inner diameter of the first pipe. The second inner diameter is substantially equal to the inner diameter of the second pipe.

  • Patent number: 10479450
    Abstract: The present invention provides a sealing device for an opening. The device includes a body that has a first side and a second side. A passageway is formed through the body such that the passageway has a first end adjacent to the first side and a second end that is adjacent to the second side. A sealing member is provided that includes an outer gasket and an inner gasket. The outer gasket is positioned adjacent the first side and the inner gasket is positioned adjacent the second side. A seal connector connects the inner gasket and the outer gasket and the seal connector passes through the passageway. In this way, the inner gasket and the outer gasket are mechanically attached to the ring. The sealing device is configured for use in such applications as sealing the cargo opening on the deck of a kayak.

  • Patent number: 10359070
    Abstract: A seal structure includes an insertion path which connects between a first opening and a second opening and through which a longitudinal member is inserted; and a seal part, formed at the intermediate section of the insertion path, which contacts with the outer circumference of the inserted longitudinal member. A discharge path is provided on a side wall section of the insertion path, and connects from the side surface of the side wall section to a section, of the insertion path, which is closer to an inflow opening through which flowing water is likely to flow than the seal part is to the inflow opening.

  • Patent number: 9890883
    Abstract: A pipe joint is provided with a pressing ring, a pipe or a pipe joint body having a containing section, a tightening element, and a packing ring compressed by being pressed by the pressing ring moved by the operation of the tightening element. The packing ring includes a base section fitted and mounted in the containing section at a rear thereof, a seal section contained within the containing section at a front thereof, and a connection section which connects the base section and the seal section and has a cutout groove. When the packing ring positioned by fitting and mounting the base section in the containing section at the rear thereof is subjected to pressing by the pressing ring, the seal section is bent into the cutout groove and is deformed, and compression caused by the deformation creates a sealed state.

  • Patent number: 9874146
    Abstract: Support strut assembly for supporting a casing of a functional unit of gas turbine is provided having a strut body for supporting the casing to ground, a ball pivot element mounted to the strut body and a rocker lever mounted to the ball pivot element. The rocker lever inserts into a bearing bore of a support body as part of the casing or ground, the rocker lever inserts into the bearing bore via clearance fit so a pivotal point is generated at a first contact area between the rocker lever and an inner surface of the bearing bore, the rocker lever pivots within the bearing bore around the pivotal point. An elastomeric springing damping element is mounted to the rocker lever between the rocker lever and the a support body providing centering force and damping pivoting of the rocker lever with respect to the support body around the pivotal point.

  • Publication number: 20110302905
    Abstract: Eyeball seals for a gimbaled rocket engines, and associated systems and methods are disclosed. A system in accordance with a particular embodiment includes a rocket body, an engine carried by and movable relative to the rocket body, and a seal assembly. The seal assembly can include a sealing surface carried by one of the rocket body and the engine, and a seal element carried by the other of the rocket body and the engine. The seal element is in contact with the sealing surface. The seal assembly can further include a cylinder and a piston slideably received in the cylinder, with one of the piston and the cylinder carrying the seal element. The cylinder includes ports that are in fluid communication with a region external to the rocket body. Accordingly, pressures external to the rocket body can force the seal element and/or the sealing surface into contact with each other.

  • Publication number: 20110198815
    Abstract: A compound conduit containing inner and outer conduits with apertures in the former that are angled to direct jets of fluid in a rearward direction from the inner conduit into the annular space is used to draw sludge or undesirable material from a vessel without imposing a vacuum on the system. In conjunction with the compound conduit is a rotary tube seal that allows the conduit to be mounted to an orifice in a tank wall and pivoted or rotated over a range of angles. A tubing drive mechanism grasps the tubing at locations well removed from the distal end and causes the tubing to travel in the direction of the tubing axis. The gripping members in the mechanism engage the sides of the tubing and are capable of shifting position relative to each other to accommodate changes in the curvature of the tubing.

  • Patent number: 6698764
    Abstract: The invention provides a packing assembly for rotating and/or oscillating machine shafts arranged in a machine housing. The packing assembly comprises a packing accommodation unit floating on said shaft. The packing accomodation unit is supported on the housing by means of a ball joint assembly that is pivotable and translatory movable in a radial direction to and from the shaft. The ball joint assembly comprises a ball member provided with a central bore received in a ball socket. A guiding element projecting into the bore of the ball member serves for translatory guiding the ball member along the axis of the bore in the ball member, whereby the axis of the bore on the ball member runs essentially perpendicular to the central longitudinal axis of the shaft.

  • Patent number: 6585416
    Abstract: A guide to support a shaft such as a pump pull rod (11) which is capable of both rotary and reciprocal motion. The guide prevents any misalignment of rod (11) damaging a seal, e.g. a stuffing box, held in space (24). Guide element (18) has central portion (19) and annular flange (25). Element (18) can move laterally with respect to housing (12) and can also pivot, along with the cap (15) of the housing (12), with respect to the lower portion (14) thereof. The latter is achieved via movements of part-spherical bearing element (28) and similarly shaped faces (26, 37, 38) of housing 9120. Further seals (33, 34) prevents entry of pumped fluid into chamber (13).
