A storage tank includes a tank wall, a pressure regulator, a low-pressure coupling, and a fill coupling. The tank wall of the storage tank is configured to contain a stored fluid at an internal pressure within the tank wall, the tank wall including an outer layer, an inner layer, and a regulator mount. The pressure regulator of the storage tank is connected to the regulator mount and is configured to receive a flow rate of the stored fluid and reduce the stored fluid from the internal pressure to an output pressure. The flow rate of the stored fluid is provided, via the low pressure coupling and at the output pressure to an external system. The fill coupling extends through the tank wall and receives the stored fluid from a fluid source to be stored within the storage tank

A self-contained breathing apparatus includes at least one air tank having a regulator, and a back plate configured to removably receive the air tank. The back plate has a plate having a tank engagement surface for engaging at least a portion of an air tank, a receiving cradle on the plate configured to receive the regulator of an air tank, and a locking mechanism associated with the cradle and/or the plate for releasably locking the regulator and/or the cradle relative to the plate. The locking mechanism has at least one locking member configured to move between a first locked position, wherein the locking member engages the regulator and/or cradle to restrict removal of the regulator and/or the receiving cradle from the plate, and a second unlocked position, wherein the locking member disengages from the regulator and/or the cradle to permit removal of the regulator and/or the cradle from the plate.

A cryogenic fluid pressure vessel for an aircraft, having: a first wall layer, which contains carbon fiber-reinforced plastic, having an inner contact surface for the contact with a pressurized cryogenic fluid to be accommodated inside the cryogenic fluid pressure vessel; a second wall layer, which is arranged on an outer surface of the first wall layer and has a thermal barrier; a closable inlet/outlet opening for cryogenic fluid, which extends through the first and the second wall layer; and a structural insert integrated in the first and the second wall layer, which has a fastening connecting piece located on the outside of the cryogenic fluid pressure vessel for mechanically coupling the cryogenic fluid pressure vessel with external structures; wherein the cryogenic fluid pressure vessel forms an essentially cylindrical main body. Furthermore, the present invention provides an aircraft having such a cryogenic fluid pressure vessel.

The invention relates to a container (1) for pressurized fluid, in particular a gas cylinder, having a given internal volume (2), having a fluid distribution valve (3) having a member for selecting the flow rate (12) able to adopt a plurality of distinct positions each corresponding to a given fluid flow rate, and an electronic device (7) having means for measuring pressure, microprocessor (15)-based data processing means (5) for processing the pressure measurements, and display means (6) for displaying the remaining fluid calculated by the data processing means (5).

The invention relates to a device (10) for holding a pressure cylinder, the device (10) having a frame element (12), a cylinder space (14) for receiving a pressure cylinder and at least one band element (16) for securing a pressure cylinder in the cylinder space (14), the band element (16) being connected to the frame element (12), wherein at least one damping element (20) is connected to the band element (16), the damping element (20) being arranged between the cylinder space (14) and the frame element (12). In this way, the invention provides an improved device (10) for holding pressure cylinders, the device (10) preventing oscillations from being transmitted into the cylinder space (14).

A mounting assembly for mounting a tank including a backing plate, a foot plate secured to a bottom portion of the backing plate and a clamping assembly secured to a top portion of the backing plate spaced from the foot plate such that a tank receiving zone is defined between the foot plate and the clamping assembly. The clamping assembly includes a bracket secured to the backing plate and a clamping member pivotally secured to the bracket and movable between a clamping position and a releasing position. The clamping assembly further includes a mechanical lock-out mechanism including a lock-out member moveable between an open position wherein the clamping member is free to pivot to the releasing position and a closed position wherein the lock-out member engages a portion of the clamping member and prevents pivoting thereof. The lock-out member is biased to the open position but moves to the closed position upon application of a high lateral force.

A valve assembly comprising a housing and a valve, the valve being disposed within the housing, a first indexed member integral to the housing, the first indexed member adapted to be complementary to a second indexed member, and a radio frequency identification device adapted to communicate with a radio frequency receiver, the valve being configured to align with a canister, seal the canister and open in a single movement. A drug containment device having said valve assembly is also disclosed.

The application provides an autonomous refueling vehicle for a hydrogen-electric aircraft, which includes two or more wings. The wings are provided with one or more removable electric propulsion pods. The autonomous refueling vehicle includes a hydrogen refueling module adapted to connect to the propulsion pods and to a hydrogen source. The autonomous refueling vehi-cle includes also includes a propulsion pod handling device, which is adapted to remove the propulsion pod from the wings and to position the propulsion pods on the hydrogen refueling module such that the propulsion pods are connected to the hy-drogen refueling module. The autonomous refueling vehicle is also adapted to autonomously move itself to the hydrogen source to allow the hydrogen refueling module to removably connect to the hydrogen source for refueling of the propulsion pods.
