Abstract: The pre-cooler includes one or more cells which are oriented about an air stream to be cooled. A housing defines a perimeter of the cell with an inlet and outlet for air passing therethrough. Water outlet nozzles within the housing are preferably supported upon bars which orient the nozzles facing in a direction counter to flow of air through the housing. Each nozzle is coupled to a separate stage with multiple stages of nozzles coupled to separate valves. A controller opens or closes different valves. The controller measures ambient humidity and temperature conditions as well as air flow rates to calculate the amount of water to be added to the air and then opens appropriate numbers of stages of valves so that an appropriate number of nozzles spray water into the air to saturate the air. Flow rate control is thus provided without pressure variations, for optimal nozzle performance.

Abstract: A method and system for automated detection and handling of film feeding failures in a high-volume CAD environment. The method provides for batch processing a set of films including multiple film cases including the steps of providing a number count of the number of films corresponding to each film case and identifying a difference between the processed number and the number count as a process error for the film case. The method also provides for batch processing a set of films including multiple film cases including the steps of providing at least one error check on the status of processing the films in the set of films and completing processing of all film cases in the set of films after a process error is identified in one film case.
