CasimerAttorney, Agent or FirmInternational ClassB65B 031/00AbstractA system for continuously filling a plurality of cylinders with a precise concentration of a vaporized liquid component blended into a gas is disclosed wherein the concentration of the liquid component of the resultant final blended mixture is continuously analyzed, and immediately adjusted, during the filling process. Due to the constant analysis and adjustment, any error in the concentration of a component is typically realized before the concentration is outside an acceptable range. The inventive system allows for a large number of cylinders to be accurately and quickly filled with the compressed, final blended mixture.Field of SearchAerosol or gas-charged typePlural materials With material treatment FILLING OR REFILLING OF DISPENSERS Aerosols By operation of means causing or controlling dispensing Expansible chamber of fluid pressure applying or controlling means Heating or cooling WITH TESTING OR WEIGHING RECEIVER CONTENT PLURAL MATERIALS, MATERIAL SUPPLIES OR CHARGES IN A RECEIVER With common discharge With mingling in or successive path through trap Filling dispensers With fluid contact (e.g., jetting) In gas filled receivers Mixing of plural fluids of diverse characteristics or conditions Controlled by consistency of mixture Controlled by pressure Controlled by conductivity of mixture Controlled by heat of combustion of mixture Mixture condition maintaining or sensing By optical or chemical property WITH HEATING OR COOLING OF THE SYSTEM Valve in each inlet With common valve operator MULTIPLE GAS Liquid inlet Gas inlet Heat exchange means at or downstream of contact zone Having mixing chamber Including mixing means Cooling only | |
