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.

An apparatus for a sterile transfer of a material incudes a second safety device which locks an actuation mechanism in a closed position and unlocks the actuation mechanism when a container flange is correctly connected to a port flange, a third safety device which locks the container flange connected to the port flange when the actuation mechanism leaves the closed position, and a fourth safety device which blocks a return of the actuation mechanism from the open position to the closed position when the port door is open. The second, third and/or fourth safety device comprises two magnetic elements with at least one closed wall being arranged between the two magnetic elements. The two magnetic elements are configured to mutually attract or to mutually repel through the at least one closed wall either in a lock position or in an unlock position of the second, third and/or fourth safety device.

A closure [10] for a cylindrical vessel includes at least one holding means [30] configured to move the closure into a fully closed state, the holding means having a predetermined actuation force or torque to properly close the closure, the closure including one or both of the following failsafe failure detection features: a mechanical fuse [20] having a predetermined load failure force below that of a load failure force of at least one component of the holding means and above that of a predetermined actuation force or torque to properly close the closure; or a block[40] sized to at least partially overlap a pressure warning lock hole [19] of the closure door when the closure is not in the fully closed state and to fully expose the pressure warning lock hole when the closure is in the fully closed state, thereby permitting insertion of a pressure warning lock [17].

An apparatus for assembling a solid hydrogen storage system includes a lower support installed to support a lower side of material blocks to be assembled, split covers assembled in multiple stages on an upper side of the lower support and forming therein a closed space in which the material blocks are capable of being assembled, the split covers being configured to be separated in a horizontal direction, and gas injection ports provided in the split covers to inject an inert gas into an inner space of the split covers.

Apparatus to protect sealing surfaces of thief hatches are disclosed. An example apparatus includes a first portion that is attachable to a tank, wherein the first portion includes a first opening, and a second portion that is pivotably coupled to the first portion. The example apparatus is structured to provide access to an aperture in the tank via the first opening when the second portion is in an open state and maintain a pressure of the tank within a specified range by selectively separating one or more seals from one or more corresponding sealing surfaces when the second portion is in a closed state, wherein the second portion includes the one or more seals and the one or more corresponding sealing surfaces.
