  • Patent number: 10731776
    Abstract: A coupling used to connect structural tubing includes segments surrounding a central space which receives the tubing. Teeth on an inner surface of the segments project toward the central space and form zones of deformation in the tubing upon engagement with the tubes' outer surfaces. Ends of the tubing abut one or more tongues on the inner surface, and observation apertures in the segments permit visual confirmation that the tubing is seated. Relief pockets on the inner surfaces of the segments receive portions of the tubing which deform outwardly. An insert may be present in the central space. The insert defines a space between itself and the inner surfaces of the segments which receives the tubing. The insert has relief channels which receive deformed regions of the tubing corresponding to the zones of deformation.

  • Patent number: 6726254
    Abstract: A fuel container with a pipe, the fuel container having a pipe connecting piece with a conically widened rim and the pipe having an annular bead, on which a connecting member acts, and a sealing ring further being seated between the conically widened rim and the annular bead. In order to make the connection such that it can be produced simply and accurately, and to make it quite tightly, on the side of the annular bead facing the pipe connecting piece, the pipe forms a cylinder with two circumferential grooves, in each of which a sealing ring is seated, which rests in a sealing manner on the cylindrical inner surface of the pipe connecting piece. The annular bead has a cross section with two oblique flanks, the conically widened rim of the pipe connecting piece resting on the flank facing the pipe connecting piece, and the connecting member acting on the flank facing away.

  • Patent number: 6125888
    Abstract: A a quick acting closure has two flanges. One of the two flanges has a groove for a flexible seal and the other has spaced cogs. The goal is to provide a quick acting closure in such a form that it can be used for the connection/closure of boiler or pipeline elements which can either have a round or a non-round cross section. In accordance with the invention, the two flanges are therefore connected to each other by individual clamps which are arranged at the circumference of the flanges and the number of which is equal to the number and the spacing of the cogs in the flange whereby the clamps are connected to each other two sheet rings, i.e. one lower and one upper sheet ring.

  • Patent number: 6041824
    Abstract: A clean air duct (300) comprises a pair of tubular bodies (302, 310), each tubular body having a pair of opposed ends (304, 306, 312, 314), one of the opposed ends of one tubular body having an annular ring (346) which terminates at an inwardly extending lip (340), the other tubular body having an outwardly extending rib (322) at one end; and a cuff (320) connecting the outwardly extending rib and the inwardly extending lip. Another clean air duct (400) comprises a first blow molded tubular body (406) having a first open end (408) and an annular ring (450) which terminates at an inwardly extending lip (444), and a second blow molded tubular body (402) which has an open end (404). A cuff (412) connects the blow molded tubular bodies to one another wherein the lip (444) exerts a compressive sealing force around the second tubular body (402). Both tubular bodies (402, 406) extend from the cuff (412) in the same direction.

  • Patent number: 5984374
    Abstract: A pipe bend for integration in a pipeline for conveying concrete has coupling flanges at the ends thereof which radially project beyond the outer surface of the pipe bend. The internal flow cross-section of the pipe bend is dimensioned essentially equal in any length portion of the pipe bend between the coupling flanges. The wall thickness of the radially outer bend portion facing away from the center of curvature increases in the conveying direction, wherein the internal flow cross-section has a ramp-like step in the radially outer bend portion at a distance from the end face of the pipe bend at the exit side corresponding approximately to twice the actual width of the coupling flange on the exit side.

  • Patent number: 5967564
    Abstract: The connection or coupling between two equipments such as pipes (1 and 2) by a clamp (17) involves the use of a second clamp (8), tightened around the fixed pipe (1) and carrying a cradle (9) for supporting the clamp (17). This arrangement makes it possible to place the coupling parts in succession and to release them immediately afterwards. The cradle (9) also prevents the clamp (17) from tilting when its clamping screw (22) is turned. Finally, a sleeve (27) maintains the extension position of the pipes (1, 2), while also centering the sealing joint (32). All these advantages make it possible to correctly and easily assemble the parts with a single remote manipulator in the hot cells of nuclear installations.

  • Patent number: 5647561
    Abstract: A system for releasably restraining a first element and a second element is disclosed. The containment system uses a tensioner to urge a clamp into contact with the first element and with the second element, and a release selectively operates the tensioner to remove the clamp from contact with the first and second elements to permit relative movement therebetween. The clamp is particularly useful in maintaining a gap between the first and second elements which permits relative movement between the first and second elements after the clamp is removed.

  • Patent number: 5411349
    Abstract: Cylindrical bodies of structural components, such as a spacecraft and a rocket section or two rocket sections, are coupled to each other by a releasable coupling device. The structural components have radially protruding flanges that face each other and are encircled by the coupling device. The coupling device includes a flexible tensioning element, such as a steel belt or link chain, the ends of which are interconnected by a clamping or locking device. The clamping or locking device is constructed as a two-armed lever, one end of which is connected to each of the ends of the tensioning element. The two-armed lever is rotatably supported and driven by an operating member such as a pipe section or rod. The two-armed lever is thus rotatable through an angle of about 180.degree. so that the ends of the tensioning element are brought into overlapping positions. When the ends are in such overlapping positions the device is locked. Rotation of the two-armed lever into the opposite direction unlocks the device.
