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.

Disclosed is an apparatus for assembling a solid hydrogen storage system. The apparatus 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.

The present application relates to a handle arrangement (1) for a door (10), comprising a handle (2) and a locking clamp (3) for engaging a locking element on a door frame (70). The locking clamp is arranged to rotate around a first axis (A) from a locking to an intermediate position and to move linearly along a second axis (B) from the intermediate to an open position, when the handle is moved between a closed, intermediate, and open state. The arrangement comprises a resilient means (8) arranged to keep the locking clamp from moving from the intermediate position towards the open position until a force applied in the direction of the linear movement of the locking clamp towards the open position exceeds a resilient force of the resilient means. With this arrangement, a handle arrangement which may be opened in several steps is provided such that the opening of a door may be performed in a controlled manner.

A container for exchanging a fluid under pressure has a cylindrical tank with caps and seals at opposite ends of the tank. The caps are moved between the unsealed arrangement and the sealed arrangement using a tie rod engaging threaded bores in the caps. Each seal is held in a groove in a flange of each cap which is spaced from a shoulder between the flange and the cap's head. In the sealed arrangement, the seals are radially compressed between the flange and the tank's interior sidewall. With a central tie rod threadedly connected to threaded bores at the center of the caps, rotating the caps relative to the tank axially moves the caps between the sealed arrangement and the unsealed arrangement. The top cap has a fill port with a threaded plug, an inlet port, and an outlet port with a tube extending to the bottom of the tank.

Each seal is held in a groove in a flange of each cap which is spaced from a shoulder between the flange and the cap's head. In the sealed arrangement, the seals are radially compressed between the flange and the tank's interior sidewall. With a central tie rod threadedly connected to threaded bores at the center of the caps, rotating the caps relative to the tank axially moves the caps between the sealed arrangement and the unsealed arrangement. The top cap has a fill port with a threaded plug, an inlet port, and an outlet port with a tube extending to the bottom of the tank.

Subassembly fora double-door leaktight connection system between two closed spaces, the system including two flanges able to be secured to each other, and two doors each normally closing an opening delimited by a flange, the subassembly including a flange and a seal, the seal being intended to provide leaktight contact between the flange and the seal, between the seal and the other flange of the connection system and between the seal and the door closing the opening of the flange, the flange including a groove and the seal being a part moulded onto the flange and being partly received in the groove.

A pressure indicator is disclosed having a coupling body and an indicator member positioned within the coupling body. The coupling body has an open first end and an open second end, an inside surface and an outside surface extending from the open first end to the open second end. The inside surface surrounds a coupling body cavity. The outside surface is threaded adjacent to the second end. The coupling body is sized and dimensioned to be threaded into a bung hole of a static storage container. The indicator member is positioned within the coupling body cavity in a sealing relationship. The indicator member, biased to a first position, is movable from the first position within the coupling body cavity to a second position outside of the coupling body cavity responsive to the coupling body being exposed to a pressure within the static storage container above a predetermined pressure threshold.

A drain petcock having a central channel for drainage, a side wall aperture for draining, and a closing plug that closes the central channel and overlies the side wall aperture. The partial removal of the closing plug enables a controlled flow for initial draining. A full removal of the closing plug enables a more controlled flow through the central channel for further draining.
