The method comprises: a first step of supplying the gas in the first tank body to the gas consuming device through the first gas supply pipe by bringing the first gas tank into the first state; a second step of bringing the first gas tank from the first state to the second state after the first step has been followed by a reduction in the amount of the gas in the first tank body to less than a predetermined reference amount; and a third step of bringing the first gas tank from the second state to the third state after the gas in the first gas supply pipe has been consumed by the gas consuming device and the pressure of the gas in the first gas supply pipe has been reduced to less than the predetermined reference pressure after the second step.

An air-storage system includes air-storage units that are in fluid communication with each other, that are in fluid communication with an air-actuated power generating system, that cooperatively enclose the air-actuated power generating system, and that cooperatively define a work area for placement of the air-actuated power generating system. Each of the air-storage units includes at least one air-storage subunit and a plurality of supporting subunits that support the at least one air-storage subunit. The at least one air-storage subunit of each of the air-storage units includes a plurality of first air-storage pipes that are colinearly arranged, that are connected to and in fluid communication with each other, and that are adapted to store pressurized air.

The gas tank disclosed herein includes a tank body, a first neck, a neck mount, a mount plate, and a plate bolt. The first neck extends from one end of the tank body along its axis and is provided with external threads on its outer periphery. The neck mount is a component for fixing the tank body to the apparatus, and has a first female screw hole that is screwed into the male screw of the first neck. The mount plate has a second female screw hole screwed into the male screw and faces the neck mount. The plate bolt presses the mount plate against the neck mount along the axis.

A valve assembly comprising a housing and a valve, the valve being disposed within the housing, a first indexed member integral to the housing, the first indexed member adapted to be complementary to a second indexed member, and a radio frequency identification device adapted to communicate with a radio frequency receiver, the valve being configured to align with a canister, seal the canister and open in a single movement. A drug containment device having said valve assembly is also disclosed.

A device configured to couple a rounding ring to a tank is provided. In one aspect, the device includes a bracket having a first leg angled relative to a second leg, the first leg comprising a tank-facing side and a first opening, the second leg configured to couple to the rounding ring; a mount comprising a tank-facing side and a stud on a second side opposite the tank-facing side, the tank-facing side of the mount configured to place an adhesive into contact with the tank when the stud is inserted into the first opening of the bracket via the tank facing side of the first leg of the bracket; a spring between the second side of the mount and the tank-facing side of the first leg of the bracket when the stud is inserted into the first opening of the bracket; and a nut configured to couple to the stud and compress the spring when the stud is inserted into the first opening of the bracket and the second leg is coupled to the rounding ring. Movement of the nut away from the mount uncompresses the spring to place adhesive on the tank-facing side of the mount into contact with the tank.

A cryogenic tank for storing cryogenic fluids is disclosed. The cryogenic tank is typically configured to be mounted on a vehicle for supplying cryogenic fuel to a propulsion system of the vehicle. The cryogenic tank comprises an inner vessel for containing cryogenic fluids and an outer vessel surrounding the inner vessel to define a vacuum insulating volume therebetween. The outer vessel is configured to transmit static and/or dynamic loads, while the inner vessel is partially or completely isolated from such loads.

In the first step, the gas in the first tank body is supplied to a gas consuming device through a first gas supply pipe by bringing the first gas tank into the first state. In the second step, the first gas tank is brought from the first state to the second state after the gas amount in the first tank body is reduced to less than a predetermined reference a amount. In the step, the first gas tank is brought from the second state to the third state after the gas in the first gas supply pipe has been consumed by the gas consuming device and the pressure of the gas in the first gas supply pipe has been reduced to less than a predetermined reference pressure.

A tank, in particular for a liquid hydrogen reservoir, provided with internal rails for putting an equipment module in place, includes a central portion provided with a wall, and at least one rail and preferably a plurality of rails, each of the rails being integrated in the wall of the central portion of the tank so as to be accessible from inside the tank, such rails allowing easier integration and fastening of a module comprising equipment inside the tank, so as to simplify the manufacture and assembly of the tank.

A (high-pressure) tank for a vehicle that includes a tank body, which defines a first end, a second end, and a longitudinal axis, and a bolster that is wound about the tank body to increase the strength of the high-pressure tank. The tank body is formed from a non-metallic material and includes a first compartment and a second compartment that is isolated from the first compartment so as to inhibit fluid communication therebetween.
