The disclosed gaseous fuel torch apparatus is adapted for use in cutting, welding, heating or other such operations involving the heating, cutting, or fusing of either metallic or non-metallic materials. The apparatus includes a fueling module for supplying gaseous fuel to a torch at an elevated pressure from a relatively low pressure gaseous fuel source, such as a natural gas supply system for example. The fueling module also preferably includes a selectively-operable alternate system for supplying such compressed gaseous fuel for other applications, including the recharging of one or more storage vessels for example. The fueling module includes features by which its gaseous fuel discharge pressure can be infinitely varied and preselectively adjusted within the capabilities of the fueling module's compressor device.

Gaseous fueled torch apparatus and fueling module therefor

The disclosure relates to a method and apparatus for sorptively storing a multiconstituent gas in, and for selectively releasing the multiconstituent gas from, a vessel having a predetermined sorbent material therein, while substantially preserving minimum quantities or concentrations of certain constituents of the gas. In such a method and apparatus, a first of the constituents of the multiconstituent gas which is preferentially sorbed by the sorbent material, is present in the multiconstituent gas in a predetermined minimum concentration level substantially less than that of the second constituent. First, the sorbent material in the vessel is sorptively saturated with a pre-storage quantity of the first constituent at a first predetermined pressure. Then the multiconstituent gas to be stored is introduced under pressure into the vessel, with the vessel being pressurized to a second predetermined pressure above the first predetermined pressure. Thus both of the first and second constituents are sorptively stored in the vessel on the sorbent material therein. When the stored multiconstituent gas is selectively released from the vessel, the sorbent material desorptively release the multiconstituent gas with the first constituent being present in at least the above-mentioned predetermined concentration as the pressure in the vessel decreases.

Method and apparatus for sorptively storing a multiconstituent gas

An apparatus for releasing gaseous material into the atmosphere employs a sorbent material that is sorptively saturated with a predetermined quantity of the gaseous material at a predetermined pressure, preferably approximately equal to atmospheric pressure. The gaseous material to be released preferably has a vapor pressure lower than the predetermined pressure at which the sorbent material is sorptively saturated. The apparatus also includes capability of selectively exposing the sorbent material to the atmosphere in order to allow the gaseous material to be desorptively released.
