The invention provides a remotely activated connecting device for connecting a wellhead and or Christmas tree positioned on a wellhead to a fracing tree that may comprise a collet system for selectively engaging and disengaging from a threaded, spiral, and or flange shoulder that may utilize hydraulics for same.

The disclosure relates to a connection arrangement for forming a fluidic connection between a container and a fluid line. A wall element is arranged in or on a container wall of the container and has an opening. A tubular connection element has two sealing surfaces. The connection element has a sealing section at the end which is arranged around the circumference on the connection element and has an axially oriented sealing surface. The connection element has a second sealing surface around the circumference at an end opposite the sealing section. The connection element has a connection section in the region of the first sealing surface for introducing into the opening of the wall element and for connecting to the wall element.

A magnetic joint includes a first member and a second member. The first member includes a first plurality of magnets spaced annularly apart from each other. The second member includes a second plurality of magnets spaced annularly apart from each other. The first member is rotatably coupled to the second member. The first member is configured to be coupled to a first component and the second member is configured to be coupled to a second component. The first plurality of magnets and the second plurality of magnets are configured to cooperatively define a plurality of rotational positions between the first component and the second component.

A quick disconnect fitting includes a plug and a socket to receive the plug. The plug includes a fluid channel, an inlet to the fluid channel, and a pressure regulating valve assembly. The valve can include a poppet, and a valve nozzle comprising an orifice. The valve assembly resides in the fluid channel. The socket includes a socket stem to contact the valve assembly and push the valve assembly into the fluid channel of the plug upon the socket receiving the plug.

Formation of a sterile connection includes inserting a first aseptic coupling device into a second aseptic coupling device, removing a first membrane from the first aseptic coupling device and a second membrane from the second aseptic coupling device, and rotating a locking clip on the first aseptic coupling device to compress a first seal member of the first aseptic coupling device with a second seal member of the second aseptic coupling device to form a sterile fluid passageway.

A flow node includes characterized restrictor in series and adjacent with a valve to provide a primary flow restriction with a minimized volume between the two. A conductance of the characterized restrictor is low enough relative to the valve seat to cause a pressure drop that is sufficiently large relative to the pressure drop across the valve seat that a pressure measurement device is located upstream of the valve is used to determine the pressure to the inlet of the restrictor. A vent can be included to reduce bleed time. Multiple flow nodes in parallel increase a dynamic range.

The invention relates to a gas venting pipe (10) for a vehicle (100) having a forward tiltable cab, which gas venting pipe comprises: a first pipe section (12) mountable to a chassis of the vehicle; a second pipe section (14) mountable to a rear wall of the forward tiltable cab of the vehicle; and a flexible magnet connection (16) adapted to releasably interconnect the first and second pipe sections. The present invention also relates to a liquefied gas driven vehicle (100) comprising a gas venting pipe, and to a method of venting gas from a liquefied gas driven vehicle.

Pair of connecting plates contain on the backside pits fitted with magnets, while at the “connected” position the connecting plates are adjacent, they have identical axially oriented polarization. The pits have passage channels and are laid-out on imaginary circles, where the neighboring magnets have alternating polarization and by pairs and/or threes are covered with magnetic hasps fitted with hasp screws. Centering and disconnection are ensured with the help of centering holes, and possibly centering dimples, fitted with connecting/disconnecting devices. Additional passages placed between two circles with magnets can be added. Possible closing device is attached by spacing posts, spacing screws and ring.

A remotely-operated fluid connection assembly to hold higher internal pressures in larger diameters. The assembly comprises a fluid connection adapter and a fluid connection housing assembly. When the adapter enters the housing assembly: (A) locking elements on the housing assembly constrict about the adapter; and (B) at least a first seal section on the adapter sealingly contacts a first seal bore on the housing assembly. Progressive engagement of a locking ring upon the locking elements urges the locking elements to tighten against the adapter. Internal pressure encourages adapter displacement, which then further tightens the adapter against the locking elements as now restrained by the locking ring. Internal pressure further encourages the first seal section on the adapter to expand radially to tighten the contact with the first seal bore in the housing assembly.
