Abstract: An exhaust treatment system includes an exhaust treatment device having a stepped outer diameter. First and second clamps each include a stepped inner diameter such that the clamps engage the exhaust treatment device and other portions of the exhaust treatment system when the exhaust treatment device is properly oriented. The exhaust treatment device interferes with one of the clamps to preclude coupling the exhaust treatment device to an adjacent portion of the exhaust treatment system when an attempt is made to install the exhaust treatment device in a reversed improper orientation. A consistent exhaust flow direction through an exhaust treatment device such as a diesel particulate filter may be maintained through use of the inventive system.

Abstract: A falling-off preventing holder is provided to reliably connect a fuel pipe and a connector. First and second flanges project outwardly from an outer peripheral surface of the fuel pipe. The connector includes a larger diameter portion and a smaller diameter portion connected to the larger diameter portion via a step portion. A box-shaped falling-off preventing holder with an open surface is fitted to straddle the fuel pipe and the connector. First cutout of first end wall is fitted on the smaller diameter portion of the connector and abuts the step portion. Second end wall is fitted on the fuel pipe to abut the second flange. A pressure rib provided at the first end wall of the falling-off preventing holder is compressed by the step portion of the connector to be plastically deformed. A load in the connecting direction acting on the fuel pipe and the connector enables reliable connection.

Abstract: An open-ended coupler for joining a pipe to a larger opening defines a passageway having straight and angled sections. The straight section has a uniform inner diameter concentric about a centerline sized to receive the outer diameter of the pipe. The angled section has a narrow end with an inner diameter less than that of a wide end and of the straight section, and being at least as large as the inner diameter of the pipe. The angled section has an upper portion above the centerline that at least in part increases in radius from the narrow end to the wide end. A lower portion has a constant radius, at least along a line extending between the narrow and wide ends at a six o'clock position with respect to the open end of the angled section.

Abstract: A clamp assembly prevents separation of a thermal sleeve penetrating a nuclear reactor pressure vessel wall and a jet pump riser elbow welded one to the other and lying within an annular space between the pressure vessel wall and core shroud. The clamp assembly includes a pair of heads having semi-cylindrical recesses. Pins project inwardly from each of the heads in the semi-cylindrical recesses and have axes which lie parallel to one another. By using actuators mounting multiple electrodes, holes may be formed in situ in the adjoining ends of the thermal sleeve and elbow. Once the holes are formed, the heads can be applied in situ with the pins being received through the holes and the heads clamped to one another. Thug, the pins in each of the sleeve and elbow prevent separating movement of the sleeve and elbow in the event of failure of the welded joint therebetween.

Abstract: A flexible entry boot assembly provides a fluid-tight fitting between a wall of a fluid containment region and a conduit passing through the wall. The flexible entry boot assembly comprises a seal member disposed within the containment region. A securing plate, disposed within the containment region, is releasably mounted to the seal member. A hollow support sleeve, integral with the seal member, extends axially into the containment region. The support sleeve has an outer surface and an inner, conduit receiving surface, and further has a degree of flexibility sufficient to allow for the insertion of the conduit at angles equal to or other than an angle normal to the fluid containment wall while maintaining a fluid-tight environment. The flexible boot assembly further comprises a mechanism for releasably attaching the hollow support sleeve to the conduit. A flexible, corrosion resistant sealing ring member is disposed outside the containment region.
