A replaceable cartridge for storing a fluid includes a pressure vessel for holding the fluid; a connecting line extending from the pressure vessel to a first connection surface on an external side of the cartridge; and a valve system comprising a first shut-off member disposed in the connecting line; wherein the connecting line has a taper in a direction of the first connection surface.

An apparatus includes a high-pressure tank, a controller, a valve, controlled by the controller, and a compressor.

Aspects and embodiments relate to a gas flow alarm apparatus and gas flow alarm method. The apparatus comprises: a device configurable to introduce back pressure into a flow of gas, a supply sensor configured to determine whether gas flow to the device is enabled; a pressure sensor configured to determine whether a flow of gas through the device has developed back pressure; and logic circuitry in communication with the supply sensor and the pressure sensor configured to determine whether gas flow to the device is enabled and whether a flow of gas through the device has developed back pressure and, if not, to activate an alarm condition. Aspects and embodiments can provide a system which operates to warn a user against various adverse conditions in which a flow of therapeutic gas to a patient is required, yet not being provided.

A receptacle for conveying fluid is disclosed. An example receptacle includes a main body defining an inlet and an outlet, a spring retainer disposed in the main body, a valve seat disposed in the main body, and a poppet configured to slide between a closed position and an open position. The poppet is slidably engaged with the spring retainer between the closed position and the open position and is engaged with the valve seat in the closed position. The example receptacle also includes a spring engaged with the spring retainer and the poppet to bias the poppet to engage the valve seat in the closed position. The spring retainer, the valve seat, the poppet, and the spring are removable from the main body via the inlet without disassembling the main body.

A fuel delivery and storage system is provided. A further aspect employs a remote central controller and/or software instructions which receive sensor data from stationary and bulk fuel storage tanks, portable distribution tanks, and end use tanks. Another aspect of the present system senses and transmits tank or hydrogen fuel characteristics including temperature, pressure, filled volume, contaminants, refilling cycle life and environmental hazards. Still another aspect includes a group of hydrogen fuel tanks which is pre-assembled with sensor, valve, microprocessor and transmitter components, at least some of which are within an insulator.

Process for vaporizing purge liquid from a cryogenic liquid vaporizer, the liquid containing at least one impurity, in which the purge liquid is withdrawn from a bath of liquid surrounding the vaporizer or resulting from the vaporizer, all of the purge liquid is vaporized in a heater, characterized in that the content of the at least one impurity in at least one portion, or even all of the heated vaporized liquid is analysed and the flow rate of at least one portion, or even all of the heated vaporized liquid is measured.

Disclosed is a pressure vessel including an upper liner portion including a top insertion-injection molded and coupled to a peripheral part of a boss portion in which a through hole extends in a vertical direction, extending downward cylindrically from the top to form a first accommodation space accommodating a fluid and having an open lower center, and including a first shape-matching portion in which a first overlapped-coupled surface is formed on a bottom end edge to be perpendicular to a laser emission direction and extends in a vertical direction along a circumferential direction and a lower liner portion having a top end edge coupled to the bottom end edge of the upper liner portion.

A high pressure tank includes two ferrules, a resin liner that covers outer parts of the ferrules at both end parts of the resin liner to fixedly install the ferrules, and a CFRP reinforcing layer formed on an outer surface side of the resin liner and attached to the resin liner at a center of a body part of the resin liner. Two leading end parts of the resin liner covering the outer parts of the ferrules protrude from end openings provided at both end parts of the CFRP reinforcing layer.

A valve assembly for pressurized containers includes a main structure, a rotary control element rotatably connected to the main structure and configured so as to allow a gas flow through the valve assembly in accordance with an angular position thereof about a main rotation axis, a detection device which includes an angular position sensor and a movable member. The angular position sensor is configured to detect the angular position of the movable member about an auxiliary rotation axis. The movable member is rotatably supported on the main structure and the angular position sensor is fixed to the main structure. The valve assembly further includes a movement conversion mechanism configured so as to convert the movement of the rotary control element about the main axis into a corresponding rotational movement of the movable member about the auxiliary axis which is different with respect to the main rotation axis.

A thermoelectric cryogenic material storage container including: an inner container containing cryogenic liquid material; a supply pipe connected to the inner container to supply the cryogenic liquid material from the outside to the inner container; an outer container for accommodating the inner container to be spaced apart from each other; a discharge pipe provided to be connected to the inner container to discharge a vaporized material of the cryogenic liquid material vaporized in the inner container to the outside of the outer container; and at least one thermoelectric module provided to have one side in contact with the outer side of the supply pipe and the other side in contact with the outer side of the discharge pipe. When current is supplied to the thermoelectric module, the other side becomes a heating side, and the one side becomes a cooling side.
