An anti-tamper device for securing a compressed gas tank that has a valve attached in a protruding manner. The anti-tamper device has a cylindrical body and a top cover. The cylindrical body has a hole located in the sidewall. The hole allows for a gas hose to be attached to the compressed gas tank. The sidewall further has a series of holes. The series of holes align in order to have a locking bar placed therein. The locking bar is designed such that the bar rests under a turn knob of the compressed gas tank. The locking bar is further designed to be placed under a handle of a compressed gas tank.

A cryogenic liquid dispensing device may include a cryogenic cylinder for containing a cryogenic liquid. A dispensing pipe may be in fluid communication with the cryogenic cylinder. A dispensing valve may be configured to govern the fluid communication between the dispensing pipe and the cryogenic cylinder. A heating element may be disposed within the cryogenic cylinder, and the heating element may be configured to generate heat within the cryogenic cylinder to increase the pressure within the cryogenic cylinder. By generating heat within the cryogenic cylinder, the pressure within the cylinder may be increased and used to motivate a cryogenic fluid within the cylinder to the dispensing valve and out of the dispensing pipe. Preferably, the device may include a processing unit that may be configured to cause the heating element to generate heat within the cryogenic cylinder when a pressure reader detects a minimum pressure within the cryogenic cylinder.

The present disclosure relates to an apparatus for fixing a pressure vessel, the apparatus including: a frame part disposed to be separable from the subject and configured to support the pressure vessel; and a foothold disposed on the frame part, thereby obtaining an advantageous effect of simplifying a structure and improving a degree of design freedom and spatial utilization.

A method of operating safety mechanism includes extending a safety pin to block a poppet from opening a flow path from a pressure vessel in the event of the pressure vessel being unmounted from a bracket or in the event of the bracket being unmounted from a support structure. The method includes retracting the safety pin to allow free movement of the poppet for opening the flow path only in the event of the pressure vessel being mounted to the bracket and the bracket being mounted to a support structure.

A transport element support assembly comprises a front plate, a back plate, and a grommet. The front plate has a first opening and a first set of holes. The back plate has a second opening and a second set of holes. A chamber is formed by the first opening and the second opening and is configured to hold a transport element. The grommet is positioned within the chamber. The transport element support assembly formed by the front plate, the back plate, and the grommet is configured to provide electrical isolation between the transport element and an aircraft structure.

An apparatus for remote inspection of fire extinguishers at one or a system of fire extinguisher stations includes, e.g., at each fire extinguisher station: a detector for lack of presence of a fire extinguisher in its installed position at the fire extinguisher station; a detector for out-of-range pressure of contents of the fire extinguisher at the fire extinguisher station; a detector for an obstruction to viewing of or access to the fire extinguisher at the fire extinguisher station; and a device for transmission of inspection report information from the fire extinguisher station to a remote central station.

The invention relates to a receptacle for receiving a cryogenic coupling for filling between two uses, the receptacle comprising a tubular sleeve which has an inlet and a bottom and delimits a tubular housing configured to accommodate a coupling of cylindrical overall shape, characterized in that the tubular sleeve is thermally insulated, and in that the bottom is situated above the inlet thereof in a use configuration such that the terminal end of the coupling is held there oriented upwards in a position stowed in the receptacle.

A storage tank assembly includes a storage tank extending along a first direction, that stores a fluid in an interior thereof, and including a discharge hole at an end portion of the storage tank in the first direction, and a connecting portion coupled to the discharge hole, and including an internal passage fluidically-communicating with the discharge hole, in an interior of the connecting portion, and the connecting portion includes a connecting portion body including the internal passage in an interior of the connecting portion body, and a rail insertion groove formed to be recessed from the connecting portion body and configured so that a rail provided on an outside of the connecting portion body is selectively inserted thereinto.
