According to the invention there is provided a system for determining a status of a gas cylinder, the system comprising: a load sensor configured to detect a weight of the cylinder at predetermined time intervals; a temperature sensor configured to detect a temperature local to the cylinder at the predetermined time intervals; and a processing unit configured to: receive weight signals and temperature signals from the load sensor and temperature sensor respectively; and determine, based on the received weight and temperature signals, the status of the gas cylinder; and provide an indication of the status of the gas cylinder to a user. A system for managing deployed cylinders is also provided. Methods and computer readable mediums are also provided.

The invention relates to a method for controlling a plurality of gas consumers (20, 21), comprising the following steps: assigning priorities to the gas consumers (20, 21), and activating or deactivating the gas consumers (20, 21) as a function of the priorities assigned. The invention further relates to a control device (1) for controlling gas consumers (20, 21).

System and method for digitally monitoring a pressure vessel for holding compressed gas, wherein the system comprises a sensor unit placeable on the pressure vessel for gathering information regarding the condition of the pressure vessel, a communication unit for wirelessly communicating the gathered information to a receiver wherein the sensor unit comprises a temperature sensor for measuring the temperature of the pressure vessel, a gas pressure sensor, at least one power unit for supplying power to the sensors and the communication unit.

Disclosed is a tank foot ring comprising: a body for supporting a pressurized tank made of polymeric material; and the body having an open end enclosing a hollow space or spaces on which a bottom portion of the pressurized tank rests and wherein the open end is in air flow communication with such hollow space or spaces, and an opposing surface for contacting a ground surface on which the foot ring rests. The opposing surface has a series of openings for drainage of water from the hollow space or spaces. Further provided is a collar for mounting on a top portion of a pressurized tank. The collar comprises: a body, a fastening system and a rotatable lid disposed on the collar. Further provided is a collar with a window cut-out for viewing tank data and a regulator mounting clip for securing a regulator of the tank in place during use.

Embodiments of a pressure regulator for delivering gas to a cooking station. The pressure regulator includes a body defining a gas inlet and a gas outlet. The body also includes a knob coupled to the body, the knob manually rotatable about an axis defined by the knob. The pressure regulator also includes a lever arm within the body. The lever arm extends to an end portion positioned adjacent the gas inlet, the lever arm pivotable via rotation of the knob such that rotation of the knob adjusts gas flow pressure through the body between about 11 inches of water column and about 8.5 inches of water column.

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.

There is provided a flow-blocking safety valve to prevent an explosion of a portable gas container, wherein, when the portable gas container overheats during use and the temperature rises above a predetermined level, a bridge hold supporting a pin of the safety valve melts and thus a pin or ball securely supported in the bridge holder becomes free to move to close a flow channel through which the gas flows, thereby blocking the gas discharge and preventing an accident occurring when the gas container bursts by overheating.

A fuel transfer adapter for a fuel cartridge, the fuel transfer adapter comprising: an adapter body; at least one fuel filling channel through said adapter body for the passage of fuel from a valve of the fuel cartridge to a fuel tank of an appliance through a filling port of said fuel tank; a fuel cartridge engaging portion at one end of the adapter body, for engaging the adapter body with the valve of the fuel cartridge; and, a port engaging portion at the other end of the adapter body for releasably engaging with the filling port, whereby the fuel transfer adapter incorporates at least one vent for the passage of vapour from the fuel tank to the atmosphere, said at least one vent being configured, in use, to transfer vapour displaced from the fuel tank by the fuel entering therein to the atmosphere. A method of filling a fuel tank of an appliance comprising the steps of: docking a fuel cartridge equipped with a fuel transfer adapter to a filling port of an appliance; applying a push force between the appliance and the fuel cartridge to open both a port filling valve and a fuel cartridge valve; applying a further push force between the appliance and the cartridge to create a fluid-tight seal between a compliant rim of the fuel transfer adapter and the filling port, and to create a fluid-tight seal between the sealing lip of a port engaging portion of the fuel transfer adapter and a wall of the filling port; allowing fuel to transfer from the fuel cartridge to the fuel tank of the appliance, and displaced vapour to transfer from the fuel tank to the atmosphere through a vent in the fuel transfer adapter; and, undocking the fuel cartridge from the filling port.

A check valve assembly includes a valve, cam and arm with float rotatably connected to the valve for insertion into a fluid storage container for filling of the container without overfilling. The valve includes a channel of narrowing diameter and restricting member movably retained within the channel. One end of the restricting member rides along the cam profile as the arm rotates the cam with the changing fluid levels. When the fluid reaches maximum fill level, the restricting member contacting the cam drops into the cam valley, driving the restricting member head into engagement with the channel neck walls and automatically sealing off the valve. First and second biasing members are disposed in the channel, preferably around the stem, and collectively provide counter force sufficient to overcome the frictional forces of the seal to open valve and move the restricting member upward.

Provided is a handle assembly for a cylinder. The handle assembly includes a shroud configured to attach to a collar of the cylinder to surround a valve port of the cylinder, the shroud having a first plurality of circumferentially spaced deflectable fingers extending downward in a first direction, and a second plurality of circumferentially spaced deflectable fingers extending upward in a second direction, and a handle configured to attach to the shroud, the handle having a body configured to surround and abut the shroud, and a first plurality of circumferentially spaced openings extending through the body. The first plurality of circumferentially spaced deflectable fingers are deflectable to engage respective openings in the collar to attach the shroud to the collar, and the second plurality of circumferentially spaced deflectable fingers are deflectable to engage a respective one of the first plurality of circumferentially spaced openings in the handle.
