A gas discharge device, for a vehicle powered by compressed gas, includes: a gas manifold having a hollow body and including at least one port configured to be in fluid communication with a compressed gas tank, and an opening for discharging gas into the atmosphere; and a pipe configured to connect the port to the compressed gas tank. The pipe is freely translatable in the port to enable a first end of the pipe to move translationally along an axis in the port.

A system for dispensing a gaseous fuel from a liquefied fuel and a method for operating such a system are provided. The system includes a storage tank, a pressure sensor, a dispenser, a temperature sensor, and a vapor supply unit. The storage tank stores a liquefied fuel including phases of liquid and vapor. The pressure sensor is configured to measure a vapor pressure inside the storage tank. The dispenser is configured to receive the liquefied fuel and dispense the gaseous fuel to a receiving tank. The temperature sensor is configured to measure temperature of the dispenser. The system further includes a vapor supply unit fluidly coupled with the storage tank and configured to provide the vapor of the liquefied fuel from the storage tank into the dispenser or in thermally contact with at least one portion of the dispenser.

The present invention relates to metalworking, in particular to producing vessels from non-heat-treatable aluminium alloys used for tanks and pressure vessels. Disclosed is a method of manufacturing a vessel, the method including: forming a tube by rolling at least one flat blank and abutting the edges thereof, friction stir welding the abutted edges and working at least a part of the welded tube into a shape of the vessel, wherein the flat blank is a sheet of a non-heat-treatable aluminium alloy preliminarily subjected to cold working with permanent deformation within the range of 0.5-15%, and said working of at least one part of the welded tube is hot working at a temperature of 230-520° C. The technical effect is a reduction in vessel weight, an increase in vessel strength, a uniform vessel strength and a reduction in the number of hot working cycles during manufacturing of the vessel. Further, the method provides reduced metal and time consumption in manufacturing a vessel from a non-heat-treatable aluminium alloy, low payload ratio, increased reliability and longer service life of the vessel produced using the method.

The cryogenic device for separating gas fraction from a liquefied natural gas flow carries out a two-stage separation of a gas fraction. The device includes a cylindrical housing provided with an inlet pipeline and an outlet pipeline, and a perforated partition arranged within the housing so as to face the outlet pipeline. The housing has two (upper and lower) portions of cylindrical shape that are connected to each other at an angle α of 135°-170°. There are two additional pipelines on the outside, one of them being used for pressure feed of a gas fraction after the first separation stage into the housing upper portion, and the other additional pipeline being used for extracting a gas fraction after the second separation stage into the gas cavity of a reservoir containing a cryogenic fuel.

An apparatus for storing and transporting a cryogenic fluid. The apparatus is carried onboard a ship. The apparatus including a sealed and thermally insulating tank intended for the storage of the cryogenic fluid in a state of liquid-vapor diphasic equilibrium, the apparatus including at least two sealed pipes passing through the tank in such a way as to define a passage for the removal of the vapor phase of the cryogenic fluid from inside to outside the tank, the two sealed pipes each including a collection end opening inside the tank at the level of the sealing membrane of the top wall. The collecting ends of two sealed pipes open to the inside of the tank at the level of two zones of the top wall which are situated at two opposite ends of the top wall.

A method for molding a composite pressure vessel liner to secure a boss to the liner is described. The method comprises providing a moldable liner having an end section with a neck and a port. A boss is positioned around the neck of the liner and the liner is heated and pressure is applied to mold the liner to form to the shape of the boss. The angle of the molded liner secures the boss in place around the liner and it is able to withstand high pressures. A tool for molding the liner and a method for using the tool is also described. The tool comprises a tool body and a pipe having external threads. The tool body abuts the liner and the boss. Winding the pipe exerts pressure on the liner, which when heated, forces the liner to mold to the shape of the boss.
