A gas cylinder monitoring system comprising a gas cylinder for receiving and distributing gas. A flow control valve is associated with the gas cylinder and operable to allow or prevent the flow of gas from the cylinder. A monitor is provided for monitoring a signal from an input device associated with the flow control valve. The monitor has an environmental parameter sensor for detecting the presence or absence of a selected environmental parameter in the vicinity of the cylinder. The environmental parameter sensor is connected to the monitor for transmitting an environmental status signal thereto. A removable cover is provided for covering both the flow control valve and the environmental parameter sensor such as to only allow access to the flow control valve when the cover is removed. A transmitter is also provided for transmitting a signal, obtained by the monitor from the input device, to a receiver.

A method for calculating the autonomy of a gas distribution system assembly including a container containing gas and equipped with at least one gas filling indicator device and a gas flow rate indicator device at the output of the container. The method includes recovering at least one item of identification information on the container and/or the gas used. The method also includes acquiring at least one image to recover a first datum on a value indicated by the gas filling indicator device and a second datum on a value indicated by the flow rate indicator device. The method also includes communicating the at least one acquired image and the at least one recovered item of identification to a computation module configured to deduce therefrom a corresponding value of autonomy of the gas distribution assembly, the computation module including at least the ability to process images.

A fuel tank comprises a circular column-shaped fuel tank body, a handle, and a first connector. The circular column-shaped fuel tank body is provided so as to be detachably attachable to a fuel-powered device. The handle is formed on one end side in a length direction of the fuel tank body. The first connector is formed on another end side in the length direction of the fuel tank body and configured such that, by installing the fuel tank body to the fuel-powered device, the first connector is connected to a second connector provided at the fuel-powered device so as to enable fuel to be supplied to the fuel-powered device.

Provided is a portable cylinder including a tank having an upper portion having a valve port, a mounting collar coupled to the upper portion of the tank, and a handle attached to the mounting collar. The mounting collar has an upwardly extending portion surrounding the valve port and a plurality of circumferentially spaced tabs extending radially outwardly from the upwardly extending portion, wherein a respective gap is formed between adjacent ones of the plurality of circumferentially spaced tabs. The handle includes a shroud portion including a plurality of circumferentially spaced ledges for abutting an underside of a respective one of the plurality of circumferentially spaced tabs, and at least one tab for engaging the mounting collar in one of the gaps, and a handle portion extending from the shroud portion and having one or more areas for grasping the handle.

A rack includes a first upper hook that opens upward and a first lower hook that opens downward, wherein the first upper and lower hooks are vertically aligned. Two or more permanent magnets are physically secured to the rack, wherein the permanent magnets are positioned to simultaneously magnetically engage a side surface of a cylindrical gas tank and magnetically secure the rack to the side surface of the cylindrical gas tank. A hose may be wound about the first and second hooks in a side-to-side configuration. In one option, the rack may include a second upper and lower hooks that extend in opposing lateral directions to receive separate hoses. In another option, the rack may be formed with tubular metal and the permanent magnets may be disposed inside vertical sections of the tubular metal. That rack may also secure a gas flow meter.

The invention relates to a container (1) for pressurized fluid, in particular a gas cylinder, having a given internal volume (2), having a fluid distribution valve (3) having a member for selecting the flow rate (12) able to adopt a plurality of distinct positions each corresponding to a given fluid flow rate, and an electronic device (7) having means for measuring pressure, microprocessor (15)-based data processing means (5) for processing the pressure measurements, and display means (6) for displaying the remaining fluid calculated by the data processing means (5).

Provided is a portable cylinder including a tank having an upper portion having a valve port, a mounting collar coupled to the upper portion of the tank, and a handle attached to the mounting collar. The mounting collar has an upwardly extending portion surrounding the valve port and a plurality of circumferentially spaced tabs extending radially outwardly from the upwardly extending portion, wherein a respective gap is formed between adjacent ones of the plurality of circumferentially spaced tabs. The handle includes a shroud portion including a plurality of circumferentially spaced ledges for abutting an underside of a respective one of the plurality of circumferentially spaced tabs, and at least one tab for engaging the mounting collar in one of the gaps, and a handle portion extending from the shroud portion and having one or more areas for grasping the handle.

A gas cylinder mobility aid is provided. A gas cylinder mobility aid for attachment to a collar of a gas cylinder, comprising a base plate having an upper surface and a lower surface. One or more coupling members affixed to the lower surface of the base plate wherein the one or more coupling members are positioned to form a frictional fit with the collar of the gas cylinder. A vertical member affixed at the center of said base plate and a handle rotatably attached to the vertical member such that the handle is present above the upper surface of the base plate and the handle rotates about the vertical member.

A handle assembly for a portable gas cylinder includes a first handle portion, a second handle portion and first and second locking members. The first handle portion includes an ergonomically configured upstanding gripping handle and a semi-circular shroud portion configured to couple to a first section of an upper portion of a portable gas cylinder. The second handle portion includes an ergonomically configured upstanding gripping handle and a semi-circular shroud portion configured to couple to a second section of the upper portion of the portable gas cylinder. First and second locking members are configured to selectively locking the first and second handle portions to one another about a periphery of the upper portion of the portable gas cylinder.

There is provided a protection structure for a gas cylinder assembly comprising a gas cylinder body and a valve. The gas cylinder body includes a base and a neck to which a proximal end of the valve is connectable in use. The protection structure comprises first and second structural sections, the first section being connectable to the valve such that the second section is spaced from the valve by the first section. Further, in use, the second section is arranged to transfer impact forces to the first section, and the second section is arranged to deform with respect to the second section in response to said impact forces to reduce the peak impact force on the valve.
