A closure is provided for a pressure vessel or pipelines that can provide quick and easy access to the interior of a pressure vessel or pipeline, and means for a pressure tight seal between the hub and door. The closure can incorporate means for mechanically fastening the door to the hub using an external split clamp ring actuated by a toggle mechanism. A locking mechanism can be provided to safeguard against unintended closure actuation, and provides a layer of redundancy to the holding characteristics of the toggle mechanism. The locking mechanism can be interlocked to a pressure alert system to ensure any differential pressure condition contained within the closure is detected prior to disengaging the locking mechanism and actuating the toggle mechanism.

The invention relates to a device for sealed transfer between two enclosed volumes, comprising a first flange and a second flange (10) which define a passage opening into the enclosed volumes and can be secured to each other by a first bayonet connection, a first door and a second door (11) which close off the passage openings and can be secured to each other by a second bayonet connection, the first door (11) being hingedly mounted on the first flange (10) by means of a hinge (4) comprising a hinge pin, characterized in that the device comprises an external manual control lever (9) which is secured to a rotary pin penetrating the first flange (10) and which is coupled to the hinge pin in such a way that the actuation of the control lever (9) drives the hinge pin, thus opening or closing the first door (11).

A container assembly includes a container body having a housing defining an internal compartment and an opening connected to the internal compartment. A cap having an engagement feature is mounted to the housing about the opening. A pressure relief valve is operably coupled with the internal compartment to vent fluid from the internal compartment. The pressure relief valve has a movable member movable between a first position and a second position. When the movable member is in the first position, the movable member is configured to cooperate with the engagement feature to restrict movement of the cap relative to the opening.

Provided is a liquid supply device including: a plug having a plug side liquid channel; a socket having a socket side liquid channel; a hand configured to grip the socket and arrange the socket in a predetermined attitude at a three-dimensional position within the motion range; and an image capturing unit configured to recognize the orientation of the plug axis of the plug. The hand grips the socket so that the socket and the plug are in an attitude where the orientation of a socket axis matches the orientation of the plug axis recognized by the image capturing unit, and the socket gripped by the hand is inserted in the plug to couple the socket side liquid channel to the plug side liquid channel.

Provided is a liquid supply device including: a plug having a plug side liquid channel; and a socket having a socket side liquid channel. The plug has a groove having a fixing groove, the socket has a body having the socket side liquid channel, a gripping unit gripped by a robot, and a sleeve member configured to adjust a position of the body relative to the gripping unit, the tip of the body runs annularly about the socket axis and has lock balls, and the sleeve member switches a state between a connected state where the lock balls are secured in the fixing groove and a released state where the lock balls are not secured in the fixing groove.

A container for exchanging fluids using pressurized air has a cylindrical tank with caps and seals at the tank's opposite ends. Grooves in the caps hold the seals, and the caps move between unsealed and sealed arrangements using a tie rod engaging threaded bores in the caps. When sealed, the seals are radially compressed between the flange and the tank's interior sidewall. The tie rod connects to threaded bores at the caps' centers. Rotating the caps relative to the tank axially moves the caps between the sealed and unsealed arrangements. The top cap has a fill port with a threaded plug. A process tube connects to either the outlet port for the fluid when the top cap has the outlet or the inlet port for the pressurized air when the bottom cap has the inlet. A float valve connects to the process tube's end for fluid flowing through the outlet.

A high-pressure hydrogen container is provided that has a simple configuration, requiring less labor for manufacture, achieving reduced manufacturing costs, and ensuring pressure resistance. The high-pressure hydrogen container includes a metal cylinder configured to store high-pressure hydrogen, a pair of lid parts configured to cover both end portions of the metal cylinder, and a plurality of fastening parts configured to fix the pair of lid parts in a state where the metal cylinder is clamped between the pair of lid parts.

Disclosed is a hydrogen generator with a door that can be opened to replace a fuel unit and closed to seal the door. A lock responds directly to pressure within the chamber to prevent opening when the pressure exceeds a threshold value. The lock includes a locking member with a lug that engages a retainer to seal the door when the door is locked and is disengaged from the retainer when the door is unlocked. An opening mechanism moves the locking member to lock and unlock the door. A movable key is engaged with the opening mechanism and the locking member when the pressure in the chamber is at or below the threshold value and disengaged from one of the opening mechanism and the locking member by an actuator (e.g., a flexible diaphragm) so the door cannot be unlocked and opened when the pressure is above the threshold value.

Examples relate to a seal assembly comprising a base unit comprising an opening and a sealing surface extending around the opening. The seal assembly further comprises a sensor to detect a distance between the sealing surface of the base unit and a sealing surface of a lid when a fastener is connecting the lid to the base unit.
