A sensor mounting assembly is configured for use with a vessel arrangement including at least four vessels. The assembly includes first and second elongated frame members, first and second rollers, and first and second sensors. The first sensor is attached to the first elongated frame member and is configured to contact the surface of the first vessel upon actuation in a first direction. The second sensor is attached to the second elongated frame member and is configured to contact the surface of the second vessel upon actuation in a second direction that is substantially orthogonal to the first direction. This disclosure also describes a method of mounting at least six sensors for use with a vessel arrangement including at least four vessels, the vessel arrangement disposed in a container in a two-by-two stacked configuration having a central space.

A container for pressurized fluid, in particular a gas cylinder, having a given internal volume, having a fluid distribution valve having a member for selecting the flow rate, which can be manipulated by a user, a position sensor configured to detect the position of the member for adjusting flow rate, and an electronic device having a means for measuring pressure and temperature, a microprocessor (-based data processing means that are configured to calculate a remaining fluid on the basis of pressure and temperature measurements, of the position of the member for selecting the flow rate and of the internal volume of the container, a timer, and display means for displaying an updated remaining fluid.

Disclosed is a pressure vessel including a boss extension portion having a cylindrical shape in which a through hole is formed at a central part to pass therethrough and a boss flange portion formed below the boss extension portion and integrally expanding outward in a radial direction along a circumferential direction in which the through hole extends in a vertical direction inward in the radial direction, a liner portion having a container shape in which an accommodation space configured to communicate with the through hole is formed to accommodate a fluid therein while a top is insertion-injection molded and seal-coupled along a bottom surface of the boss flange portion, and a sealing portion seal-coupled to a boundary area between a bottom of the boss flange portion and a top of the liner portion to block a leakage of the fluid accommodated in the accommodation space.

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.

The invention relates to a protective valve ring (1) for an oxygen gas cylinder (3). The protective valve ring (1) comprises a body (4) adapted to enclose an outlet (5) of a cylinder valve (2). The body (2) comprises an incombustible and heat absorbing material, and has an internal shaping adapted to guide any potential oxygen gas leak away from inflammable parts of the gas cylinder (3). The invention also relates to a shut-off valve (2) for controlling flow of a pressurised gas and a method for attaching a protective valve ring (1) to a shut-off valve (2) of an oxygen gas cylinder (3).
