A sealed joint assembly for transmitting high temperature and high pressure fluid between adjoining ducts in, for example, an aircraft bleed air system, includes a gimbal ring and two annular clevises. Each clevis includes a pair of axially-extending lobes that each includes a bore hole extending therethrough. The bore holes of the clevis lobes may each align with a respective bore hole formed within the gimbal ring, through which a pin may be inserted to couple the clevises to the gimbal ring. The clevises and gimbal ring may be formed using additive manufacturing. The gimbal ring may include a strut or truss network, and may be comprised of an inner gimbal ring and an outer gimbal ring.

An improved device for coupling rigid non-metallic conduits is disclosed. The claimed device is capable of allowing movement in an axial direction due to expansion and contraction and can also compensate for angular or parallel deflection of the conduits.

A floating joint and retainer connection device includes a fixed retainer internally defines a receiving space; an adaptor joint having an end extending through the receiving space to an outer side of the fixed retainer and an axially limiting section formed near another end; a fixing element fitted on the adaptor joint and located outside the fixed retainer for limiting the adaptor joint from moving axially while allowing the adaptor joint to displace radially relative to the fixed retainer; a rolling assembly disposed adjoining the fixed retainer; and a spring located in the receiving space and fitted on the adaptor joint with two ends pressed against the axially limiting section and the fixed retainer or the rolling assembly. When the rolling assembly rolls to displace radially relative to the fixed retainer, a radial frictional force produced by a normal force applied by the spring to the fixed retainer is reduced.

An apparatus includes a first coupling member for receiving a first device and a second coupling member connected to or formed with the first coupling member at a proximal end portion of the first coupling member. The second coupling member includes a revolving exterior surface having a first revolving segment proximal to the first coupling member and a second revolving segment distal to the first coupling member. Each of the first and second revolving segments of the revolving exterior surface has a first side and a second side that is narrower than the first side. The second sides of the first and second revolving segments of the revolving exterior surface face each other. The revolving exterior surface is automation-compatible and operable by a robotic arm, facilitating automation of the first device.
