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 hose connector is disclosed that provides a magnetized connection of hoses, tubes, cables, ducts, pipes, chains, straps, wires, twine, cord and/or rope creating a continuation in length for versatile and extended flow for, but not limited to, watering needs eliminating conventional connector threads currently requiring multiple turns to release or attach or existing pronged coupling requiring a degree of hand agility and strength. Thereby the disclosed matter provides the means for a fast, single motion attachment or twisting detachment of, but not limited to hose, tube, cable, duct, pipe, chain, strap, wire, twine, cord and/or rope ends without requiring the hand strength or precision that some conventional hose, tube, cable, duct, twine, cord, and/or rope connectors may require. There may be any combination of connecting the ends of hoses, tubes, cables, ducts, pipes, chains, straps, wires, twines, cords, and/or ropes. In some scenarios, flow is not required.

The invention is a tapping assembly for use on a pipe or tank. It includes a hollow body that sits flush on the outer wall of the pipe or tank and includes a plurality of locking members that sit flush within the body and form a threaded portion into which a cap is insertable. Each locking member extends into the interior of the pipe or tank, and has an outwardly extending flanged portion that engages with the inner sidewall of the pipe or tank. When the cap is tightened against the body, it causes each of the locking member to retract, thereby causing the respective flange portions to lock the assembly against the pipe or tank wall. The assembly can be manufactured to provide either an orthogonal tap, or an angled tap, relative to the longitudinal axis of the pipe, or plane of the tank sidewall.

A coupling device for a fluid transport tube (100) having an end provided with an internal chamfer (101), the device comprising a body (1) including a cylindrical wall (2) defining a channel (3) having an end segment provided with means for securing the tube end thereto in leaktight manner, these means including an elastically deformable annular sealing element (6) comprising a support ring (61) having an axially projecting first face from which there extends a tubular portion (62) having a free end (63) arranged to bear against the internal chamfer (101) of the tube end (100) in order to be forcibly engaged in the tube end while the tube is being inserted into the end segment.

A build material container outlet structure comprises: a first connector portion to connect to a build material container; a second connector portion comprising an adaptor to receive a nozzle structure of an external aspiration system; and an aspiration channel to aspire build material from the build material container to the nozzle structure of the external aspiration system; wherein the first connector portion is rotatably connected to the second connector portion to align the adaptor in a predetermined orientation.

A vertical connection system for subsea connection of a first tubular member to a second tubular member, the system comprising a lower coupling member comprising an upright casing which encloses a liquid-filled space, wherein a hub of the first tubular member is fixed to the casing at an upper end thereof and the first tubular member extends through said space; and an upper coupling member, which comprises a guide frame configured to slidingly receive said casing when the upper coupling member is lowered downwards onto the lower coupling member, wherein a hub of the second tubular member is fixed to the upper coupling member. The guide frame is provided with a layer of thermally insulating material on its outside. The liquid-filled space is delimited downwards by a bottom wall formed by thermally insulating material or covered by a layer of thermally insulating material.

A system for selectably fastening a female member with a male member adapted to fit inside the female member, the female member having one or more inward-facing recesses and the male member having one or more outward-facing recess, the recesses being of similar cross-sectional dimensions, includes one or more moveable, ferromagnetic locking elements housed within the inward-facing recesses of the female member; and a locking magnet mounted onto the male member, in magnetic proximity to the one or more outward-facing recesses, wherein, in the presence of a magnetic force applied by the locking magnet, mating of the male and female members bringing the outward-facing and inwardly-facing recesses into mutual registration causes the locking elements to move inwardly into the outward-facing recesses so as to extend across both of the inward- and outward-facing recesses, thereby to lock the male and female members together.

A fastening structure includes a circular sleeve and a coupling member. One end of the circular sleeve has a receiving trough. A bottom of the receiving trough is provided with a first magnetic member. A wall of the receiving trough is provided with a protruding post. At least one guide groove is formed on an outer wall of one end of the coupling member. One end of the guide groove is an open axial groove having an opening. Another end of the guide groove is a closed axial groove having a stop end. The guide groove has a transverse groove between the open axial groove and the closed axial groove. Another end of the coupling member is a pivot end that has a central passage extending inwardly. A second magnetic member is disposed in the central passage. The first and second magnetic members have repulsive magnetic poles.

A subsea wellhead assembly is provided. The subsea wellhead assembly comprises: a conductor; a subsea wellhead; and subsea riser system equipment mounted on the subsea wellhead; wherein the subsea riser system equipment is connected to the conductor such that forces can be transmitted from the subsea riser equipment to the conductor.
