A pressurized gas tank comprises at least two cylinders and a rail capable of fluidly connecting the at least two cylinders. At least one cylinder includes a base for connection to the rail. The rail includes at least one reception area of a shape substantially complementary to a shape of the base. The base has a shape substantially revolutionary about a first axis and comprises a number at least equal to n of angularly equidistant tapped holes . The at least one reception area comprises a number equal to n of ports, in the form of an arc of a circle, angularly equidistant, of width substantially equal, by greater value, to a diameter of a tapped hole and of angular extent substantially equal to 360°/n.

Improvements in machining systems that utilize machining fluids comprising a supercritical fluid are described. Some systems may provide centralized distribution of a supercritical machining fluid and/or a lubricant to a plurality of machining tools in a machining facility. Other systems may allow for selective delivery of multiple machining fluids to a machine tool. For example, a supercritical machining fluid and a non-supercritical machining fluid may be selectively delivered to a machining tool as desired for a particular machining process.

A method and apparatus for cooling a compressed fuel gas during transfer of the gas from a source vessel to a receiving vessel. The method includes receiving a portion of the fuel gas from the source vessel in an intermediate vessel. Then, fluidly isolating the intermediate vessel from the source vessel. Work is then extracted from the fuel gas by causing or allowing expansion of the fuel gas, thereby cooling the fuel gas. Finally, the cooled portion of fuel gas is released from the intermediate vessel to the receiving vessel.

Hydrogen discharge system for a truck and truck comprising such system The invention concerns a hydrogen discharge system (14) for a truck, this system comprising a pipe (16) provided with at least one discharge opening (162), a deflector (18), that is rotatably mounted with respect to the pipe and that includes a vent, for venting hydrogen exiting through the discharge opening. The system further includes a balancing weight (22) secured to the deflector (18), so as to maintain the deflector in a configuration wherein the vent is facing upwards with respect to the ground, in order to always discharge hydrogen upwards relative to the ground.

A doser for dispensing a cryogenic fluid includes a doser body configured to receive the cryogenic fluid. A dosing arm has a proximal end and a distal end, with a central passage extending between the proximal and distal ends and configured to receive cryogenic fluid from the doser body. Multiple dosing heads are mounted to the distal end of the dosing arm with each of the dosing heads including a dosing valve. The dosing heads are configured to receive cryogenic fluid from the central passage of the dosing arm and to dispense the cryogenic fluid when the dosing valve is opened.
