The present invention relates to a device for transferring exhaust gas between a front and rear carriage of a mobile working machine, in particular a dump truck, separated by an articulated pivot joint, which working machine has a pipe section, which is variable in it length, for conducting exhaust gas, a first flexible hose cooperating with a first end portion of the pipe section for introducing exhaust gas into the pipe section, and a second flexible hose cooperating with a second end portion of the pipe section for discharging exhaust gas from the pipe section. The device is characterized in that a first cardan shaft is provided in the first end portion, the distal end of which is configured to be rigidly attached to a fastening section of the front carriage or the rear carriage of the working machine, and a second cardan shaft is provided in the second end region.

Aspects of the disclosure relate to fluid injection systems, apparatus, methods, and associated components thereof that include flexible hoses for wellhead sites. In one implementation, a fluid injection system for wellhead sites includes a pump, a pump manifold, and a flexible hose coupled between the pump and the pump manifold. The flexible hose includes a first end coupled to the pump and a second end coupled to the pump manifold. The first end of the flexible hose includes a first end fitting coupled to the pump, and the first end fitting is oriented at an angle relative to a horizontal plane. The second end of the flexible hose includes a second end fitting coupled to the pump manifold, and the second end fitting is oriented vertically and perpendicularly to the horizontal plane.

The invention relates to a multipart pipe joint (10) having a centre piece (16) on which joint parts (18, 20) are received which are pivotable relative thereto and which are rotationally fixed to the centre piece (16) at articulation points (22, 24). The articulation points (22, 24) of the joint parts (18, 20) on the centre piece (16) also represent articulation points (22, 24) for transmission elements (42) which extend axially along an inner wall (34) of the centre piece (16). The articulation points (22, 24) forming articulation axes are arranged in an axial offset (25) to each other. Furthermore, the invention relates to the use of the multipart pipe joint (10) in an aircraft.

A fracturing fluid delivery system is provided. In one embodiment, the system includes a fracturing manifold and a fracturing tree. A fluid conduit is coupled between the fracturing manifold and the fracturing tree to enable receipt of fracturing fluid by the fracturing tree from the fracturing manifold through the fluid conduit. Further, the fluid conduit is an adjustable fluid conduit that provides a line-of-sight fluid connection from the fracturing manifold to the fracturing tree. Additional systems, devices, and methods are also disclosed.

A bearing assembly suitable for a fluid delivery system such as a hydraulic water cannon, including for a first pipe that is moveable relative to a second pipe, the assembly comprising a main body adapted to be connected to an end of the first pipe, an annular centre swivel adapted to be connected to an end of the second pipe, the centre swivel including an annular, axially extending boss extending away from the main body, with the opposed radially extending face extending radially outwardly from said boss, and a bearing end cap adapted to engage around the second pipe and be fastened to the main body securing there between said centre swivel. The bearing assembly is adapted to operate at water pressures greater than 10 bar.

A vehicle (e.g., a material collection vehicle) may include a hose (e.g., a suction hose), a drive assembly, and a telescopically extendable boom assembly. The hose drive assembly may include a plurality of roller subassemblies adjustably mounted so that the roller subassemblies may be moved to a first position during extension of the hose and moved to a second position during retraction of the hose. The telescopically extendable boom assembly may include a conduit assembly and a support assembly. The conduit assembly and the support assembly may be operably secured together so that telescopic extension of the support assembly drives extension of the conduit assembly. The support assembly may include a drive system including an extension chain and a retraction chain.

Aspects of the disclosure relate to fluid injection systems, apparatus, methods, and associated components thereof that include flexible hoses for wellhead sites. In one implementation, a fluid injection system for wellhead sites includes a platform, a pump manifold mounted to the platform, and a pair of rails mounted to the platform. The fluid injection system includes a trolley disposed between the pair of rails and above the pump manifold. The trolley is movable along the pair of rails. The fluid injection system includes an articulation arm device mounted to the trolley. The articulation arm device includes one or more pivot joints coupled between two or more arms, and a connection device coupled to an end arm of the two or more arms.

A coupling assembly for a blind mate fluid coupling includes a housing, a sliding base disposed within the housing, the sliding base having an internal passage with a first portion and a second portion connected at a middle opening, the internal passage extend in an axial direction, the second portion has a larger diameter than the first portion, the sliding base being movable in a radial direction that is perpendicular to the axial direction and relative to the housing, and an inlet valve that is at least partially disposed in the internal passage, the inlet valve being movable in the axial direction within the internal passage and angularly pivotable at the first portion.
