An apparatus comprises an engine, an exhaust manifold fluidly coupled thereto, and an auxiliary system positioned downstream of and fluidly coupled to the exhaust manifold. A slip joint assembly fluidly couples the exhaust manifold to the auxiliary system and includes a slip joint male portion fluidly coupled to the exhaust manifold which includes a plurality of lobes positioned on an outer surface of the male portion. The male portion defines a first passageway in fluidic communication with the exhaust manifold. The assembly also includes a slip joint female portion fluidly coupled to the auxiliary system and including a second passageway. The male portion is insertable into the female portion for fluidly coupling the male portion to the female portion. Only the plurality of lobes contact an inner surface of the second passageway. Moreover, the male portion is axially slidable within the second passageway while maintaining the fluid coupling therebetween.

A gripping element includes a body extending lengthwise from a first end to a second end. The body includes a first wall, a second wall extending from the first wall, and a third wall extending between the first wall and the second wall. The first wall, the second wall, and the third wall collectively define a hollow interior of the body. The body also defines an opening at each of its first and second ends. The opening at each of the first and second ends is in communication with the hollow interior of the body to permit an elastomeric material to be received within the opening at the first end of the body, within the hollow interior of the body, and within the opening at the second end of the body.

A connection piece for pipe connections, which connection piece comprises a tubular envelope having a first end and a second end, which connection piece comprises a channel between the first end and the second end, the channel being delimited by an inner surface of the envelope of the connection piece, which connection piece comprises a first connection area extending to a distance from the first end and a second connection area extending from the second end to a distance, which connection piece has been configured to be bent in a first plane, such as vertical plane, by an angle alpha () which is 0-20 degrees, and/or in a second plane, such as horizontal plane, by an angle beta () which is 0-20 degrees. The invention also relates to a conveying pipe arrangement and to a method.

The invention relates to a hose connector (1) having a sleeve-shaped union nut (2) which (2) surrounds a sleeve-shaped connector part (3) that (3) is connected to a hose end (4) of a flexible hose line (5) and that (3) has, at its end region oriented away from the hose end (4), an annular flange (6) which (6) bears rotatably against an annular shoulder (7) of a circumferential wall (8), and having at least one sealing ring (9) which is held in a retaining groove (10) provided on the outer circumferential side of the connector part (3) and radially seals an annular gap provided between the connector part (3) and the circumferential wall (8). The hose connector (1) according to the invention is distinct by the fact that, between the connector part (3) and the circumferential wall (8), there is provided a clearance that is dimensioned such that the connector part (3) and the circumferential wall (8) can be tilted with respect to one another (see FIG. 1).

A separation preventive pipe joint having an adjustable angle of deflection. A lock ring storage groove accommodates a metallic lock ring that can be engaged with a spigot protrusion and a cushioning material that comes into contact with a bottom of the lock ring storage groove and a side wall on a socket opening side. The cushioning material is made of a material softer than the lock ring.

A device and method of simple design for measuring displacement between a first part and a second part that are substantially coaxial, preferably mounted on one another by an annular linear link. The device includes a structure for mounting the device on the part, blades secured to the structure and bearing on an outer surface of an intermediate member, the member being mounted around the part, at least one strain/deformation sensor associated with each blade, the sensors configured to transmit output signals dependent on the levels of deformation of the blades, and a conversion unit configured to deliver, from the output signals, at least one datum corresponding to the relative position of the parts, preferably out of an azimuth angle, an elevation angle and an axial displacement.

There are provided a pipeline structure and a computer readable recording medium having recorded thereon a program that supports the design of the pipeline structure. The pipeline structure includes two collars and a plurality of short pipes. The plurality of short pipes are connected by joint structures. Two collars are arranged to sandwich a zone where a fault displacement is expected to occur, and thereby, a ground displacement in the pipe axis direction is dealt with (absorbed). The plurality of short pipes are connected by the larger number of joints than the number of joints in the case of arranging a long pipe. By increasing the number of joints, it becomes easier to deal with (absorb) a ground displacement in the direction perpendicular to a pipe axis.

A tool is disclosed for use in installing and removing a sleeve from a coupling, such as a flexible coupling assembly configured according to SAE Aerospace Standard AS1650, for example. The tool may comprise a pair of arcuate coupling halves pivotally joined at first adjacent ends and latchably connectable at second ends and comprising an inner profile closely interfacing with and circumferentially surrounding the outer surface of the sleeve, and providing a shoulder extending radially inward to abut a first edge of the sleeve while leaving radial clearance between the shoulder and the annular flanges of the coupling so that the sleeve, while removably held by the tool, may be longitudinally translated onto and off the coupling without mechanically interfering with the annular flanges.

A bathtub drain connection system includes a first drain pipe configured to couple to a drain opening of a bathtub and a second drain pipe configured to mount to a floor structure. A drain connector is extends between the first drain pipe and the second drain pipe so that the first drain pipe and the second drain pipe are coupled in fluid communication. The drain connector is configured to allow the first drain pipe to be disposed offset relative to the second drain pipe and in a direction that is substantially parallel to a plane defined by the floor structure.
