Abstract: A sensor module for connection between a fabrication tool and the head of the fabrication tool. The sensor module has an interface connectable to the fabrication tool, having: a power port for receiving power transmitted by the fabrication tool to the head, a gas port for receiving gas delivered by the fabrication tool to the head, and another interface connectable to the head which has another power port for delivering power to the head, another gas port for delivering gas, from the first gas port, to the head. The module also has a sensor module having a memory, a sensor for measuring power transmitted to the head, another sensor for measuring the gas delivered to the head, a device for transmitting information between the sensor module and a remote location, and a processor electronically connected to the memory, transmission device, and sensors.

Abstract: A device for ventilating leaks from cylinders containing flammable gas when being transported in a closed vehicle, The device comprises an enclosure into which the gas cylinder may be placed, the enclosure including means to contain any leakage from the gas cylinder and then extract any leaked gas from the closed vehicle.

Abstract: A Digital intelligence Unit (CIU) for use with gas cylinders is provided with two distinct parts, a Base Intelligence Unit (BIU) that provides basic functionality and a Customer Intelligence Unit (CIU) that provides greater processing functionality and that may be customized to meet individual user needs.

Abstract: A device for supplying a shielding gas to a welding torch, the device including a cylinder 1 for holding the shielding gas, a valve operatively connected to the cylinder for selectively permitting flow of gas from the cylinder, a regulator for controlling the pressure of the gas flow from the cylinder, and a guard assembly 2 coupled to the cylinder 1 and adapted to protect the valve and regulator from external forces, wherein a flow meter 4 incorporated into the guard assembly 2, the flow meter being adapted to receive the nozzle 5 of a welding torch and measure the flow rate of the gas therein.

Abstract: A wheel assembly for a pressure vessel of the type having an inner pressure vessel and an outer protective jacket. The apparatus includes a de-mountable wheel assembly having at least one jacket engagement feature, arranged to operatively engage with the protective jacket in use, and at least one wheel. The wheel assembly is arranged to be operatively connectable to the protective jacket when the pressure vessel is resting on its base.

Abstract: A device 1 for delivering a partially-ionised first stream of gas, comprises a generator 24 of non-thermal plasma having a plasma generating chamber 25 defining a flow path therethrough for the first stream of gas and communicating downstream of the chamber with at least one first outlet 30 from the device for the partially ionised first stream of gas. The device 1 additionally comprises at least one second outlet 34 from the device for a second stream of gas, the configuration of outlets 30 and 34 enabling the second stream to shield the first stream downstream of the said first outlet 30. Interaction of the first stream of gas with the surrounding atmosphere is thus kept down.
