An adjustable gaseous fluid extractor assembly including a first portion and a second portion. The assembly further includes a pivot mechanism providing that the first portion is pivotable relative the second portion about a respective first and second axis. The assembly further includes a flexible tubing element coupled to the first portion and to the second portion. The pivot mechanism is arranged exterior the flexible tubing element.

A flexible coupling for coupling sections of a downhole tubing string is provided. The flexible coupling has a central section with first and second ends, each end having a contact surface and a first part of a pivoting connector, the contact surface extending radially outward relative to the first part of the pivoting connector. The flexible coupling also has first and second coupling sections pivotally coupled to the first and second ends of the central section. Each of the first and second coupling sections have a tubing string attachment at a first end, a second part of the pivoting connector at a second end, and a contact surface at the second end, the contact surface extending radially outward relative to the second part of the pivoting connector. Pivotal movement of the first and second coupling sections relative to the central section is limited by engagement between the contact surfaces.

Breathing tube assemblies for use with a respiratory therapy device, such as a continuous positive airway pressure (CPAP) device, includes an elbow that permits adjustment of a position of the breathing tube assembly relative to the respiratory therapy device. In some arrangements, the breathing tube assembly includes a breathing tube and a swivel elbow. The breathing tube is rotationally fixed relative to the respiratory therapy device and the swivel elbow rotatable relative to the breathing tube. In other arrangements, the breathing tube assembly includes an elbow that can be coupled to the respiratory therapy device in one of several possible positions.

The invention relates to a device for connecting pipe ends (80, 82) of double-walled pipes (72, 74) for angular compensation and for length compensation of the relative movements of the double-walled pipes (72, 74) relative to a double-walled connector (10). On the double-walled connector (10), there are arranged concentrically with respect to one another first and second ball heads (20, 26). These are each sealingly engaged over by ball cages (52, 54). The ball cages (52, 54) are formed on double-walled attachments (46) of the double-walled pipe ends (80, 82). The sealing function for double-walled angular compensation and double-walled length compensation are configured so as to be decoupled from one another, and are therefore optimized, in the case of the device proposed according to the invention.

A transport element support assembly comprises a front plate, a back plate, and a grommet. The front plate has a first opening and a first set of holes. The back plate has a second opening and a second set of holes. A chamber is formed by the first opening and the second opening and is configured to hold a transport element. The grommet is positioned within the chamber. The transport element support assembly formed by the front plate, the back plate, and the grommet is configured to provide electrical isolation between the transport element and an aircraft structure.

A duct assembly may include a first duct, a second duct, and a flexible joint assembly coupling the first duct to the second duct. The flexible joint assembly may include a bellows having a first end and a second end and a plurality of convolutions located therebetween, and a gimbaled joint assembly. The gimbaled joint assembly may include a first support surrounding the first end of the bellows and a first portion of the plurality of convolutions, a second support surrounding the second end of the bellows and a second portion of the plurality of convolutions, and a gimbal ring assembly operably coupled to the first support and the second support. The gimbal ring assembly may include a ring body and a plurality of flexure hinges interconnected with the ring body.

A bendable joint includes a first articulation pipe, a second articulation pipe, and a lock. The first articulation pipe includes a first articulation portion at one end. The second articulation pipe includes a second articulation portion at one end. The first articulation portion is articulated with the second articulation portion so that the first articulation pipe is rotatable relative to the second articulation pipe. The lock is on the first articulation pipe and is configured to lock and adjust relative positions of the first articulation pipe and the second articulation pipe.

An apparatus and method for the manufacture and maintenance of flexible joint gimbal systems. The apparatus and method reduce metal corrugated bellows gimbal joint fatigue damage due to loose fitting parts by implementing a spherical washer to reduce clearance in the flexible joint of the gimbal within desired tolerances.
