Abstract

718,080. Mixing gases in proportion. TALLEY, H. A. E. July 8,1953 [July 8. 1952], No. 17129/52. Class 86 [Also in Group VI] Apparatus for mixing gases comprises a first compressed gas supply with a pressure regulating valve connected thereto, a jet-forming nozzle and associated venturi-like tube arranged in an outlet conduit, the jet-forming nozzle being connected to the pressure regulating valve, a second compressed gas supply with a pressure regulating valve connected thereto, and a vacuumoperated supply regulator connected to receive gas from the second compressed gas supply and to pass gas to the venturi-like tube according to the depression caused therein by the passage of the first gas through the jet-forming nozzle. A cylinder 1 of compressed gas is connected to a jet-forming nozzle. 4 in a supply conduit 11 through two pressure regulators 2, 3. A second cylinder 6 is connected through one side of the diaphragm of a vacuum-operated gas flow regulator 8 and a variable control valve 9 with a venturi-like tube 10 surrounding the jet-forming nozzle 4 so that flow of gas from the cylinder 6 is dependent on the depression produced in the venturi-like tube 10 by gas issuing from the jetforming nozzle 4. The other side of the diaphragm of the vacuum-operated regulator 8 is connected with the conduit 11 by a pipe 12.
