Abstract: A cryogenic air separation process and method in which air is cooled and after compression and purification then rectified in a rectification column to produce an oxygen rich liquid. An argon-oxygen stream containing liquid lean in nitrogen is separated to form oxygen and argon streams. Argon vapor is condensed to supply reflux to the argon column. An oxygen rich liquid stream is expanded to a pressure at which the oxygen rich liquid is at or below the condensation temperature of the argon vapor and is then vaporized against condensing the argon vapor. The vaporized oxygen rich liquid is then introduced into a nitrogen stripper column and nitrogen is stripped therefrom by a stripper gas to produce the argon-oxygen liquid which is introduced into the argon column.

This allows the system to be operated at much lower superheat temperatures than heretofore attained, yielding improved performance and longer component life.

Abstract: An automatic atmometer includes an evaporating head that is coupled to a metering vial through a three-way valve controlled by fluid sensors disposed proximate inlet and open ends of the metering vial. The three-way valve is ordinarily in a quiescient state that connects the evaporating head to the metering vial. As water evaporates from the evaporating head water is drawn by suction out of the metering vial. When a sensor proximate the inlet of the metering vial indicates that the vial is empty the three-way valve is activated. This refills the metering vial from a fluid reservoir above the metering vial. As soon as one or more sensors proximate the open end of the metering vial indicate that the vial is full the three-way valve is returned to its quiescient condition. An output signal activates a counter or other logging device to record the number of times the metering vial has been emptied and refilled.
