The present disclosure relates to a natural gas hydrate tank container loading system for transporting natural gas hydrate, and the present disclosure provides a natural gas hydrate tank container loading system, enabling self-powered power generation and boil-off (BOG) gas treatment, includes: a refrigerator for inhibiting the generation of boil-off gas which naturally generates in a natural gas hydrate tank container during transportation; and a solar cell, a battery, and a generator, which operates by means of the boil-off gas, for supplying electric power to the refrigerator, thereby ensuring a generation capacity sufficient to operate the refrigerator by means of the solar cell, the generator, and the battery, and thus always maintaining a stable phase equilibrium (self-preservation) in the natural gas hydrate tank container even during long-distance transportation and solving problems of fire, environmental pollution, or the like which occur when the boil-off gas (BOG) is discharged to the outside.

A metering device for attaching to a container configured to store a fluid, the device including: a valve configured to control the amount of fluid dispensed from the container; a user interface comprising at least one control configured to operate the valve between an open position and a closed position; and a control circuit configured to set a threshold amount of the fluid to be dispensed from the container, where the control circuit is configured to override the user interface and close the valve when the threshold amount of fluid to be dispensed has been reached.

A pressure vessel system for a vehicle includes a pressure vessel and a fuel line. The system also includes a blocking unit which, in an inoperative state, prevents fuel from passing out of the pressure vessel into the fuel line. A control unit for the blocking unit is designed, under the action of electrical energy, to transfer the blocking unit from the inoperative state into an active state in which fuel can pass out of the pressure vessel into the fuel line. Furthermore, the system includes an electrically conducting connection to an electrical system of the vehicle via which electrical energy can be provided for controlling the blocking unit. In addition, the system includes an access interface unit via which electrical energy for controlling the blocking unit can be provided from an external energy supply if no electrical energy is available from the electrical system of the vehicle.

A device for supplying pressurized fluid, comprising a first valve) and a second valve accommodating internal circuits, the first valve and the second valve including respective coupling members that form a quick-connection system for removably connecting the second valve to the first valve, the internal circuits including a set of one or more control valves the device including at least one manually actuable mobile control member for controlling the set of one or more control valves, between a first, rest position, in which the flow of fluid towards the outlet is prevented, and a second, active position, in which the flow of fluid towards the outlet is allowed, the quick-connection system including a connection piece for connecting the second valve to the first valve between a first position.

An energy storage assembly for a motor vehicle, including a traction battery for storing electrical energy. A flexible pressure element, which is filled with gas or liquid is disposed on the outside of the traction battery or on the inside of a covering component for the traction battery, the gas or the liquid is contained at atmospheric pressure within the flexible pressure element. A pressure sensor is connected to the flexible pressure element, and by which collision-induced pressure fluctuations in the flexible pressure element can be sensed.

An apparatus, system and method for measuring quantity of a material are disclosed. One or more sensors are used to measure the quantity of the material are measured and error causing parameters are also measured. Error causing parameters are processed by executing one or more correction methodologies to determine a correction output. The quantity of the material is measured by using the correction output. One or values associated with the quantity of the material are measured and displayed. The one or more values are transmitted to a server and informative messages are received from the server.

The present invention relates to a natural gas hydrate tank container loading system for transporting natural gas hydrate, and the present invention provides a natural gas hydrate tank container loading system which enables automated connection of an electric power line and a boil-off pipe, and may automatically connect an electric power line and automatically connect the pipe by simultaneously stacking respective natural gas hydrate tank containers, in order to solve problems of a transportation method using the existing natural gas hydrate tank containers in the related art in that an operation of connecting an electric power line to a refrigerator for minimizing the occurrence of boil-off gas and maintaining a phase equilibrium condition in the tank containers and an operation of connecting the pipe for discharging the boil-off gas need to be manually and individually performed for long-distance transportation of a large amount of natural gas hydrate by using a ship, which causes an inconvenience.

A system and device for monitoring the content of a gas/liquid or gas only containment vessel such as a cylinder is provided. The disclosed apparatus is easily affixed to a standard gas cylinder and configured to monitor the pressure of the cylinder contents and activate a visual and/or audio alarm when the contents of the gas/liquid cylinder are no longer in a liquid or partially liquid state as well as activate another visual and/or audio alarm at a prescribed pressure when the contents of the cylinder are nearing depletion.

A valve arrangement (10) adapted to be coupled to, and to provide a gas flow from, a gas cylinder (20) containing a pressurized gas (21), the valve arrangement (10) comprising a blocking valve (1) with an obturator (11) movable by an actuator (12) from an opening position permitting a flow of the pressurized gas (21) through the blocking valve (1) into a closing position blocking the flow of the pressurized gas (21) through the blocking valve (1) is provided. Temperature sensing means (4) are provided which are adapted to provide at least one signal, the at least one signal being indicative of one or more temperatures of, in, and/or in vicinity to, the valve arrangement (10), and the actuator (12) is adapted to move the obturator (11) from the opening position into the closing position if the one or more temperatures indicated by the at least one signal are above a predetermined threshold value.
