A method of vaporising liquefied natural gas (LNG) for measurement of its constituent components may include receiving LNG from a main pipeline into a pressurising device. The method may also include via the pressurising device, pressurising a the LNG beyond a critical pressure thereof. The method may further include directing a first portion of the pressurised LNG to a heater. The method may still further include via the heater, heating the first portion of pressurised LNG beyond a critical temperature thereof, and directing the pressurised and heated LNG to a vaporising device. The method may also include via the vaporising device, depressurising the heated LNG to a pressure below the critical pressure so as to vaporise the LNG.

To suppress the degradation of sealing property of a pressure vessel and the deterioration of a sealing member, and to reduce the workload and cost of manufacture, a blow molding device includes a pair of molds configured to be clamped to sandwich a parison from both lateral sides, and a blow pin configured to form a neck portion together with the molds. The blow pin includes a blow pin body portion having an outer circumferential surface of a shape corresponding to an inner circumferential surface of the neck portion, and a ring portion forming an annular recess portion between the blow pin body portion and the ring portion to form an outer circumferential surface of a tip portion of the neck portion, which is a smooth surface without any parting line.

A fluid-distribution assembly has controllable components. The fluid-distribution assembly also has a vehicle-fuelling connection configured to be selectively connectable to a first compressed-natural-gas tank of a first compressed-natural-gas-powered vehicle. The fluid-distribution assembly also has a fuel-storage connection configured to be selectively connectable to a fuel storage assembly. The fluid-distribution assembly is configured to be electrically connected to a controller assembly. The controller assembly is configured to monitor and control operations of the controllable components of the fluid-distribution assembly. The controllable components of the fluid-distribution assembly are configured to selectively distribute, under control by way of the controller assembly, a fluid flow of a compressed natural gas between the first compressed-natural-gas tank and the fuel storage assembly.

A filling station comprises a filling device for an automated filling of a gas bottle inserted in the filling station and a filling device for refueling a motor vehicle, wherein the filling device for an automated filling of a gas bottle inserted in the filling station is arranged adjacent to the filling device for refueling a motor vehicle.

In a hydrogen or helium container and method for containing the gas, a double-walled housing is provided, which defines an inter-space between the inner and the outer walls, the inter-space being filled with a fluid at a higher pressure than the pressure of the hydrogen or helium contained within the inner wall.

A storage tank for liquid hydrogen comprises first and second shells each constructed of laminate material, the second shell being disposed outwardly of the first shell with respect to the centre of the storage tank. The first and second shells are mechanically connected by a first plurality of pins each of which passes through at least some layers of the second shell and at least some layers of the first shell. The storage tank may be constructed using a simpler manufacturing process involving less tooling and fewer process steps than is the case for known tanks for storing liquid hydrogen. The storage tank has also has a lower mass and reduced thermal losses compared to tanks of the prior art. The plurality of pins allows for the shells to be thinner, and hence lighter, than similar shells in tanks of the prior art.

A device for storing and transporting liquefied gas, including a first inner reservoir extending in a longitudinal direction, a second outer reservoir, the device having a system for holding the first reservoir in the second reservoir having a first rigid connection between the first reservoir) and the second reservoir at a first longitudinal end, and, at a second longitudinal end of the device, a mechanism for suspending the first reservoir inside the second reservoir having an assembly of tie rods, a first end of the tie rods being attached to a sheath that is secured to the first reservoir via a washer(s) and nut assembly, these being fitted around the tie rod, a second end of the tie rods being attached to a sheath that is secured to the second reservoir via a washer(s) and nut assembly.

The invention relates to a filling level measuring device for measuring the filling level in a container through the wall thereof by means of ultrasound, having an ultrasonic measuring head, a controller, and a fastening device by means of which the filling level measuring device can be fastened to the container such that the ultrasonic measuring head is pressed against the wall of the container. The invention further relates to a method of operating such a filling level measuring device, wherein a sampling rate is used which is situation-dependent. The invention finally relates to an assembly made up of such a filling level measuring device and at least one spacer which can be attached to the lower edge of a container to be provided with the filling level measuring device.

Device for filling tanks with pressurized gas, in particular hydrogen gas tanks of motor vehicles, the device comprising at least one gas source, a transfer circuit comprising at least one upstream end connected to the source and at least one downstream end intended to be connected in removable fashion to a tank to be filled, the transfer circuit additionally comprising, between its upstream and downstream ends, a set of buffer storage container(s) which is (are) connected in parallel to the transfer circuit via a set of respective connecting valve(s), the transfer circuit comprising a portion of pipe(s) forming a loop, a plurality of the buffer storage container(s) being connected in parallel to the said loop, characterized in that the transfer circuit comprises a plurality of separate downstream ends each intended to be connected in removable fashion to a respective tank to be filled, the said downstream ends being connected in parallel to the said loop and comprising a set of respective linking valves, so that control of the connecting valves and of the linking valves makes it possible to bring at least one first buffer storage container into fluidic communication, via the loop, with a first downstream end and, simultaneously, to bring at least one second buffer storage container into fluidic communication, via the loop, with a second downstream end and/or to bring two separate buffer storage containers into fluidic communication.

Station for filling one or more tank(s) with pressurized gas, in particular pressurized hydrogen, comprising at least two pressurized gas source stores, a transfer pipe having an upstream end connected parallel to the source stores and a downstream end intended to be connected to a tank to be filled, the station comprising a valve assembly for controlling the transfer of gas between the sources and the tank to be filled and an electronic controller connected to the valve assembly and configured to control the valve assembly, the electronic controller being configured to implement successive transfers of gas between the source stores and the tank to be filled via successive pressure balancing sequences, the electronic controller being configured to determine the temperature attained by the gas in the source stores or by the source stores during transfers of gas and, when said attained temperature is below a determined threshold, to prevent or to interrupt this transfer of gas or to reduce the flow of gas transferred during said transfer.
