The present invention provides a leak-proof fluid dispensing system with a pressure sensor and an adjustable dispensing regulator, comprising: a gas cylinder and a pressure dispensing control valve. The dispensing control valve is formed outside the bottle body opening and has an internal channel that communicates with an inlet port, an outlet port, a bottle port, and the joint portion. The internal of the dispensing body includes an inlet valve, an outlet valve, a pressure dispensing regulator, a filter, and a pressure sensor. The pressure at the outlet end of pressure dispensing regulator is lower than or equal to a preset opening pressure value, the fluid is allowed to flow out. With the implementation of the present invention, it may prevent accidental leakage of fluid in the gas cylinder and dynamically monitor the flow gas capacity in the gas cylinder.

A cryogenic energy storage system comprises at least one cryogenic fluid storage tank having an output; a primary conduit through which a stream of cryogenic fluid may flow from the output of the fluid storage tank to an exhaust; a pump within the primary conduit downstream of the output of the tank for pressurising the cryogenic fluid stream; evaporative means within the primary conduit downstream of the pump for vaporising the pressurised cryogenic fluid stream; at least one expansion stage within the primary conduit downstream of the evaporative means for expanding the vaporised cryogenic fluid stream and for extracting work therefrom; a secondary conduit configured to divert at least a portion of the cryogenic fluid stream from the primary conduit and reintroduce it to the fluid storage tank; and pressure control means within the secondary conduit for controlling the flow of the diverted cryogenic fluid stream and thereby controlling the pressure within the tank. The secondary conduit is coupled to the primary conduit downstream of one or more of the at least one expansion stages.

Method, system, apparatus, and/or device for monitoring a shipment. The vapor plug system includes a vapor plug. The vapor plug fits onto a shipper and partially seals contents within a payload area of a shipper. The vapor plug system includes a sensor that is configured to measure or determine a condition or location of the shipper. The vapor plug system includes an electronic device that has a display. The display is configured to provide the condition or the location to a user. The vapor plug system includes a vapor plug adapter. The vapor plug adapter includes a recessed pocket that is configured to receive the electronic device. The vapor plug adapter includes an opening within the recessed pocket and is configured to receive the sensor and allow the sensor to be inserted into the payload area of the shipper.

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).

A system and device for monitoring the content of a gas/liquid or gas only containment vessel such as a cylinder is provided. The disclosed apparatus is easily affixed to a standard gas cylinder and configured to monitor the pressure of the cylinder contents and activate a visual and/or audio alarm when the contents of the gas/liquid cylinder are no longer in a liquid or partially liquid state as well as activate another visual and/or audio alarm at a prescribed pressure when the contents of the cylinder are nearing depletion.

A valve arrangement (10) adapted to be coupled to, and to provide a gas flow from, a gas cylinder (20) containing a pressurized gas (21), the valve arrangement (10) comprising a blocking valve (1) with an obturator (11) movable by an actuator (12) from an opening position permitting a flow of the pressurized gas (21) through the blocking valve (1) into a closing position blocking the flow of the pressurized gas (21) through the blocking valve (1) is provided. Temperature sensing means (4) are provided which are adapted to provide at least one signal, the at least one signal being indicative of one or more temperatures of, in, and/or in vicinity to, the valve arrangement (10), and the actuator (12) is adapted to move the obturator (11) from the opening position into the closing position if the one or more temperatures indicated by the at least one signal are above a predetermined threshold value. A gas supply system (100) and a corresponding method of gas supply is also part of the invention.

The present invention provides an apparatus for producing medical foam for wound care or hair stimulation. The apparatus includes a foam generation unit having a fluid reservoir, a fluid delivery line and a foam generation tip. The apparatus also includes a compressed gas unit having at least one container of compressed gas, a source of electric power, and a gas regulator valve. A supply of wound care or hair stimulating solution is communicably connected to the foam generation tip such that when the apparatus is operated medical foam is produced by the foam generator tip.

Fluid tanks in a hospital or similar environment include sensors to detect, e.g., state and location, which can be communicated to a central station where this data can be processed to permit predictions of resource usage and enable automated management of the fluid tanks.

A simulated smoking device (1) comprising a simulated cigarette having a substantially cylindrical cigarette-like shape and a refill device (2, 50) having a substantially cuboid housing with a cigarette pack-like shape containing refill gas (32, 59) for the simulated cigarette and having means for selectively retaining the simulated cigarette. The simulated cigarette may be retained wholly within the housing. It may be retained at a location different from the refill location. A dose counter may be provided to give a visual indication of the doses in the refill device.

A valve integrated pressure regulator (VIPR) device that can be attached to the outlet of a gas cylinder, which can monitor the amount of gas in the cylinder is provided. Features of the disclosed device include an electronic control, electronic alarm and the electronic display that are powered by rechargeable battery that may be disposed within the VIPR shroud or within a removable cylinder base affixed to a bottom of the gas cylinder. Additional functionality and security features may be provided via additional internally disposed sensors and/or wireless or hard-wired communications with one or more auxiliary devices.
