  • Patent number: 5362229
    Abstract: In a semiconductor wafer heat-treating apparatus, there is provided a piping connection device on a gas inlet pipe leading to the heat-treating apparatus and a gas outlet pipe derived from the heat-treating apparatus. The piping connection device has a spherical convex connecting element, and a concave connecting element having a concave spherical surface into which the spherical element is snugly fitted. A pair of presser plates are placed on the outer surfaces of the two connecting elements and clamped by bolts so as to press confronting sealing surfaces of the convex and concave connecting elements against each other. Because the outer surfaces of the two connecting elements to be engaged with the pair of presser plates are spherically fashioned, the connection surfaces can present a satisfactory sealing condition without subjecting the pair of the pipes connected by the piping connection device to excessive biasing forces even though the two pipes are angled to each other.

    Abstract: A bellows sealed ball joint comprising an inner spherical shell, a bellows and an outer spherical shell. The inner spherical shell comprises a plurality of elongated non-spherical areas or indentations which receive a plurality of locking surfaces on the outer spherical shell. The inner and outer spherical shells can then be rotated with respect to each other a predetermined distance until the spherical locking surfaces on the outer spherical shell operatively engage concentric spherical locking surfaces on the inner spherical shell. Once the locking surfaces of the inner and outer spherical shells are in operative engagement, the bellows ball joint can pivot freely without becoming disconnected. A final joining seal is then made at each end of the bellows to prevent the spherical sections from unlocking and to provide a hermetic seal. In an alternate embodiment, the inner spherical shell is shown as having elongated slots in place of the non-spherical areas.

    Abstract: An articulated pipe line comprising rigid sections jointed together so as to allow a limited angular movement between adjacent sections, the axis of two successive articulations having different directions and a sealing device ensuring a tight separation between the outside and the inside of the pipe line at the level of the articulation. This device is particularly suitable for immersed pipe lines of large diameter.

  • Patent number: 4360226
    Abstract: The present invention relates to a connector for mechanically joining members having large force loading while enabling limited relative angular movement therebetween. The connector employs a plurality of stacked metal roll plates to provide rolling metal-to-metal contact while avoiding sliding movement of contacting members transmitting the force load between connector members. Each of the roll plates is provided with a concave and convex load carrying surface with the radius of the concave surface greater than that of the convex surface to provide rolling rather than sliding contact. To obtain universal angular movement, one embodiment of the connector employs a single stack of spherical surface roll plates while a second embodiment employs a plurality of roll plate stacks having substantially cylindrical load carrying surfaces.

  • Patent number: 4322098
    Abstract: A swivel assembly comprises a housing having a bore extending therethrough along a central axis. The housing has an end wall with an opening about the axis extending therethrough. A generally spherical swivel member is rotatably and swivelly disposed in the bore and includes an extension protruding through the opening. The portion of the extension within the opening is substantially smaller in transverse cross-section than the opening to permit limited swivel movement of the swivel member in the housing. The bore has first and second sections. The first section has a smaller diameter than the second section and thereby forms a wall. A stiff resilient element is provided between the wall and the swivel member for preventing movement of the spherical swivel member when subjected to a heavy load.

  • Patent number: 4225260
    Abstract: A joint assembly having a socket member, a stud member, and restrainer elements constructed and arranged to prevent the socket and stud members from pivoting relative to each other in one plane containing the longitudinal axis of the stud member while permitting the members to pivot in a plane at a right angle to such one plane and containing such axis and permitting the stud member to rotate on such axis with respect to the socket member.

  • Patent number: 4155670
    Abstract: A ball joined to a first element, a hole through the ball and first element, a socket, having a spheroidal internal surface, joined to a second element, a hole through the socket and second element, said socket containing the ball in mating and nesting arrangement with the hole in the ball communicating with the hole in the socket, one of the ball and the socket containing at least one cam slot extending along a line of longitude, a cam follower having an axle joined to one of the ball and the socket at the equator and extending into the slot in the other one, and said ball and socket being rotatable relative to each other around only two of three orthogonal axes intersecting at a point in the radial center of the ball.

  • Patent number: 4018463
    Abstract: This invention provides a pipe joint which includes a first pipe end and a second pipe end juxtaposed in substantial alignment. The pipe joint is capable of providing for movement of one pipe end with respect to the other, and also for pressure-compensation. A sleeve member spans between and externally of both pipe ends. Two annular ring structures are positioned between the pipe ends and respective ends of the sleeve member. Sealing surface engagement takes place between each annular ring structure, its respective pipe end, and the sleeve member. Articulating means are provided for interconnecting each annular ring structure with the opposite pipe end, thereby to permit the pressure-compensation.
