  • Patent number: 6328809
    Abstract: The present apparatus is a method and system for treating and drying the surface of an object. According to the described method, with a wet object positioned in a vessel, a drying vapor is introduced into the vessel. The drying vapor condenses on the surface of the object and reduces the surface tension of the residual process fluid, causing the residual process fluid to flow off of the surface. In one embodiment, wet processing of the object and a subsequent evacuation of process fluid is carried out in the vessel prior to introduction of the drying vapor.
    Type: Grant
    Filed: January 8, 1999
    Date of Patent: December 11, 2001

  • Patent number: 6170703
    Abstract: Described herein is a chemical injection system and method utilizing a chemical storage vessel coupled to a bulk source of chemical and proportioned to contain a volume of chemical useful for multiple applications for which the chemical is to be utilized. A dispense vessel proportioned to contain a volume of chemical useful for a single application is fluidly coupled to the chemical storage vessel. A controller controls operation of a system of valves and sensors, which operate to fill the chemical storage vessel, and to precisely dispense the volume required for a single application from the storage vessel into the dispense vessel and then ultimately into the vessel in which the chemical is needed.
