A gas cylinder monitoring system (10) for monitoring the contents of a gas cylinder in an EMS vehicle (50) including a gas cylinder (12) for receiving and distributing gas therein, an individual cylinder monitoring system (14) operable to monitor data associated with the gas cylinder (12) and having a cylinder monitoring transmitter (16) operable to broadcast the data, and at least one receiving station (60,70) having a receiver (18,20) operable to receive the data from the individual cylinder monitoring system (14) and indicate if the contents of the gas cylinder (12) are below a pre-determined threshold and require replacing.

A pressure vessel and a method of manufacturing the pressure vessel is provided that reduces leaks in type IV pressure vessels having a liner with a corrugated section. The method includes providing a liner having a tubular portion having a corrugated section with circumferential corrugations providing alternating ridges and grooves arranged from one end to an opposing end of the corrugated section, applying a barrier to an outer surface of the corrugated section from one end to an opposing end of the corrugated section such that air voids are formed in annular cavities between the liner and the barrier; and applying resin to an outer surface of the barrier. The barrier prevents intrusion of the resin between the barrier and the liner in the corrugated section.

Apparatus comprising a source of a first fluid (204), a fluid displacement device (210) for moving the first fluid from the source to a sealed storage chamber (214), means for introducing a second fluid (207), different from the first fluid into the first fluid prior to reaching the storage chamber, the arrangement being such that the sealed storage chamber receives a mixture of the first and second fluids under a pressure greater than the pressure at the point at which the second fluid is introduced into the first fluid and includes a first fluid outlet (220) for directing the first fluid separated from the second fluid in the storage chamber externally of the storage chamber.

A valve for closing a gas container includes a valve body with a continuous longitudinal bore along a longitudinal axis and a displaceably-guided valve tappet mounted therein. The valve body extends longitudinally parallel to the axis from a connection region with a connection-side end face to a fastening region with a gas-container-side end face having a smaller diameter than the connection region. The connection region has a stop face that stops a gas container base-body head when the fastening region has been inserted into an opening in the head. The valve body laterally has a double groove in the fastening region that includes two grooves that follow one another longitudinally and that a sealing lug facing away from the longitudinal axis separates to allow the head to be pressed gas-tightly with the fastening region in the double groove region when the fastening region is introduced into the head.

Pressurized gas bottles with integrated valves, in which a plurality of functional supports are integrated in an extraction unit, are equipped with complex fall protection means. Moreover, in such a valve, a new approval procedure is carried out for the entire valve in the event of multiple modifications, for example when supplementing it with an additional function. In order to reduce the effort associated with this, an extraction fitting for a pressurized gas bottle is provided with a modular design, wherein a base module comprising the shut-off member and a fall protection device securing the shut-off member complies with legal requirements regarding fall protection and the shut-off device of the pressurized gas bottle. All further functionalities of the extraction fitting are integrated in at least one additional module, which is connected to the base module in a fixed but removable manner and without impairing the fall safety.

A pressure control device including a valve with a fluid inlet and a fluid outlet, wherein the fluid inlet is in selective fluid communication with the fluid outlet. A heat collector is adapted to cover portion of an envelope of a pressure vessel and operative to receive heat from a heat source. A sensing element is in thermal communication with the heat collector and operative to receive the heat from the heat source. Operative to receiving heat from the sensing element receives the heat, the sensing element actuates the valve to establish the selective fluid communication between the fluid inlet and the fluid outlet.

A method of generating a pressurized, sub-cooled mixed-phase cryogen is disclosed, including providing a cryogenic system including a reservoir containing a liquid cryogen; and a heat exchange coil immersed in the liquid cryogen, the heat exchange coil having an input end and an output end not immersed in the liquid cryogen; introducing a pressurized gas cryogen to the input end of the heat exchange coil; cooling the pressurized gas cryogen within the heat exchange coil; and collecting the pressurized gas cryogen at an output end of the heat exchange coil.

An arrangement comprising at least one liquefaction plant for liquefying a gaseous medium to produce a liquefied medium; and at least one storage tank for storing the liquefied medium. A first transfer line is provided which is connected between the liquefaction plant and the storage tank, for transferring liquefied medium from the liquefaction plant into the storage tank. A second transfer line is connected between the liquefaction plant and the storage tank, for transferring gaseous medium from the storage tank into the liquefaction plant. The second transfer line, which used for transferring medium from the storage tank into the liquefaction plant, is arranged so that it is routed at least partially through the area of the storage tank in which the liquefied medium is stored in use.
