A coupling system for fluid transfer between a bow area of an elongated vessel and a hydrocarbon delivery installation at open sea. The system includes a support frame for suspending the system to the vessel and a fluid receiving tube segment fixed to the support frame comprising a coupling device arranged at a first end of the tube segment and that establishes a leakage free coupling with a hose valve. The system further includes a remotely controlled drive system that simultaneously exerts a transverse force generating pendulum movements of the coupling device in the transverse plane, a longitudinal force generating pendulum movements of the coupling device in a longitudinal plane, and a rotational force generating rotational movement of at least part of the coupling device iteratively adjusting the rotational position of the at least part of the coupling device by regulating the rotational force.

A coupling device for joining two lines has two coupling parts that are coupled and connected together in the axial direction to connect the two lines to each other, and wherein the two coupling parts are fixed to each other via a plurality of spring-loaded coupling elements distributed in the circumferential direction of the coupling device, such that the two coupling parts are operable to be bent relative to each other with respect to a normal position by forces acting laterally with respect to the axial direction of the coupling device, and wherein the coupling elements in the bent position exert a restoring force on the coupling parts in the direction of the normal position by the spring load.

Wearable rubber parts for fluid handling systems include a four layer structure, wherein the inner most layer of the four layer structure is a polyurethane layer. The polyurethane can be millable polyurethane. The polyurethane used in the inner most layer can be produced by reacting diisolcyanate with a polyester and/or polyether polyols and a chain extender. The wearable rubber part can be an expansion joint, a pinch valve, or a hose.

An expansion joint, which connects pipes to each other and is capable of expanding and contracting, the joint being provided with: a first end pipe and a second end pipe; a connecting pipe for connecting the first end pipe to the second end pipe so as to be capable of approaching and separating from each other; and a thrust-absorbing device having a pressure chamber, which can expand and contract in the direction in which the first end pipe and the second end pipe are linked and into which a fluid pressure that differs from the pressure inside the pipes can be introduced, the pressure chamber comprising a first pressure-receiving section, which is fixed to the first end pipe and faces in the direction from the second end pipe toward the first end pipe, and a second pressure-receiving section, which is fixed to the second end pipe and faces in the direction from the first end pipe towards the second end pipe.

A propulsive assembly including a turbine engine configured to be fastened to an aircraft by means of a suspension, having certain casing portions suitable for being decoupled so as to attenuate certain bending modes of the turbine engine in the event of an incident, the propulsive assembly comprising at least first and second casing portions (33a, 22) extending axially one after another, one of said casing portions being cantilevered out relative to said suspension, wherein a first casing portion (33a) possesses a first fastener portion (41) connected rigidly to the body (43) of the first casing portion (33a) and a second fastener portion (42) connected more flexibly to the body (43) of the first casing portion (33a), and wherein the second casing portion (22) is fastened to the second fastener portion (42) of the first casing portion (33a) in a manner that is permanent, and to the first fastener portion (41) of the first casing portion (33a) in a manner that is releasable.

According to one embodiment, a flange joint for joining a first pipe to a second pipe includes an adapter coupled to the first pipe. The adapter includes a convex surface. The flange joint also includes a gasket with a first concave surface and a second convex surface. The first concave surface of the gasket is matingly engageable with the convex surface of the adapter. The second convex surface is matingly engageable with the second pipe. The gasket is supported on the first pipe. The flange joint further includes a clamp that includes a concave surface that is matingly engageable with the second pipe to secure the gasket to the adapter.

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 wastewater tank arrangement for an aircraft, including a wastewater tank and a drain pipe having a first end and an opposite second end, the drain pipe fastened with its first end to the wastewater tank and having a second end for connection to a service panel in the aircraft structure. Providing a wastewater tank arrangement can effectively compensate tolerances between the wastewater tank and the service panel, and can effectively compensate installation and manufacturing tolerances during the course of the initial installation, in that the wastewater tank arrangement has a tolerance compensation device configured to connect the second end of the drain pipe to the service panel and compensate tolerances between the second end of the drain pipe and the service panel.
