The fluid transfer connector includes: a plug including a plug body, the plug body including a fluid channel; a socket including a socket body, the socket body including a fluid channel that communicates with the fluid channel of the plug body when the plug is connected to the socket; and a driving mechanism configured to adjust a distance between the plug body and the socket body. The plug body and the socket body can be stopped by the driving mechanism at an initial position where the plug body and the socket body are spaced from and face each other, a connecting position where the fluid channel of the plug body communicates with the fluid channel of the socket body, and an intermediate position between the initial position and the connecting position.

Provided is a fluid transfer connector plug that allows for easy engagement of keys with key grooves. The fluid transfer connector plug includes: a plug body having a proximal end and a distal end, the proximal end allowing a hose to be fixed thereto, the distal end being removably connected to a socket, the plug body including a fluid channel communicating with the hose; a key plate on an outer periphery of the plug body, the key plate being rotatable relative to the plug body; and two or more keys on the key plate. The plug further includes a main key having a larger circumferential width than that of each of the other keys.

A method for connecting sections of a multi-bore structure in water comprises connecting the sections to bring corresponding bores of the sections into mutual alignment while those bores are each closed by a plug that excludes the water from the bores. Then, with the sections connected and the corresponding bores sealed together in fluid communication with each other, the plugs are flushed away in a flushing fluid that flows along the communicating bores.

Exemplary embodiments relate to unique structures for robotic end-of-arm-tools (EOATs). In particular, exemplary embodiments provide structures allowing a displacement fluid to be discharged from a distal end of a robotic finger. The discharge may be used to displace a target object, such as an object that is adjacent to another blocking object or the side of a container. After the target object is displaced, the EOAT may be better able to maneuver into a gripping posture and may be able to secure a better grasp on the target object.

A device (1) for connecting fluid-conducting lines (2) and/or chambers (3) in a high-frequency electromagnetic field. The device includes two line bodies (4, 6) each having a line body inner wall (5, 7), which is rigid per se, and a bellows (8). The line body inner walls together enclose an inner cavity (9) for the passage of fluid through the device, and the line bodies are connected to one another, and enclosed with a sealing action, by the bellows and the first and second line bodies can be displaced and/or tilted relative to one another. The second line body inner wall projects a little into an interior space (10) surrounded by the first line body inner wall and ends there and the first line body inner wall is electrically conductively connected to the second line body inner wall by at least one elastically deformable sliding contact (11).

A connector for use in an ultra-high vacuum system is disclosed herein. The connector has a metal conduit section with a first hardness, a metal fitting with a second hardness greater than the first hardness, and a metallic reaction-inhibiting barrier positioned between the conduit section and the fitting to sealingly attach the fitting to the conduit section. In some embodiments, application of a mechanical stressor such as stretching or treatment with a mechanical oxide disruptor removes oxide from and prevents oxide re-formation on the faying surface of the conduit section. In alternate embodiments, oxide is removed from the faying surface of the conduit section and oxide re-formation is subsequently prevented by applying an oxide inhibitor. The reaction-inhibiting barrier substantially inhibits metallic and chemical interaction between the conduit section and the fitting under ultra-high vacuum, temperature cycling, mechanical stress, and reactive chemical conditions, as are present during manufacturing.

A heating, ventilation, and/or air conditioning (HVAC) system includes a conduit assembly with a first conduit segment, a second conduit segment, and a rotational fitting fluidly coupling the first conduit segment and the second conduit segment to one another. The conduit assembly is configured to fluidly couple to a port of a heat exchanger of the HVAC system, and the rotational fitting is configured to enable the first conduit segment and the second conduit segment to rotate relative to one another between a first orientation and a second orientation and maintain a connection between the first conduit segment and the second conduit segment during relative rotation between the first conduit segment and the second conduit segment.

A reinforcement assembly may be provided for a bracket configured to constrain a cooling pipe of a spent fuel pool of a nuclear reactor. The reinforcement assembly includes a base structure defining back slots, angled slots, side slots, and/or front slots. Back boss structures may be configured to slidably engage with the back slots of the base structure. Pipe boss structures may be configured to slidably engage with the angled slots of the base structure. Side clamps may be configured to slidably engage with the side slots of the base structure. Each of the side clamps may define a vertical slot. Vertical clamps may be configured to slidably engage with the vertical slot of each of the side clamps. Front clamps may be configured to slidably engage with the front slots of the base structure.

A riser connector assembly includes a first connector assembly portion with first locking members, a second connector assembly portion with second locking members, and a locking device with third and fourth locking members. The locking device is rotatably connected to the first connector assembly portion. The locking device rotates between a first position where each of the locking members are interlocked, a second position where the first and third locking members are interlocked, and the second and fourth locking members are not interlocked, and a third position where none of the locking members are interlocked, so that the locking device is removable. The first and third locking members selectively/releasably interlock via a relative rotation between the first connector assembly portion and the locking device. The second and fourth locking members selectively/releasably interlock via a relative rotation between the second connector assembly portion and the locking device.

A composition for solid coating formation, includes a mixed solvent including water and a dipolar aprotic solvent, a powdery organic resin which is partially soluble at least in the dipolar aprotic solvent. The powdery organic resin is dissolved or dispersed in the mixed solvent.
