Abstract: An apparatus and process for allowing a powder paint system to utilize reclaimed oversprayed powder paint of various colors by collecting it in a common reclaim collector system. The reclaimed powder paint is then applied to a work piece as a base coat to attain a portion of the total film build required. The remainder of the film thickness is then applied in subsequent application of virgin powder paint.

Abstract: An improved contaminant shield and method for making the shield, including one or more panels constructed of interconnected frame members, such as extruded aluminum, having longitudinal recesses and consisting of substantially closed sections in closed sections in cross-sections. Thin flexible sheeting is inserted within the frame members, and fastening members are used to frictionally engage the recesses and capture the sheeting in seli-tensioned position.

Abstract: A process for treating paint sludge in which previously cured paint sludge powder is used as a diluent and mixed with wet paint sludge. The paint powder/sludge mixture is agitated and heated to cure the paint sludge. Processing can occur either continuously or in batch mode, and can be accomplished using a mixer charged with heated gases, or a heated mixer.

Abstract: An integrated paint spray booth and air conditioning system and process utilize a spray booth housing, scrubber and filtering chambers located below the housing, and an air conditioning apparatus including an adiabatic saturator. The components are arranged to direct the air flow in the system substantially transverse to the length of the system. The air is conditioned to predetermined psychrometric values by sensing only the temperature of the water entering the saturator and the air exiting the conditioning apparatus.

Abstract: An apparatus for use in measuring fluid flow across a boundary is disclosed including a conduit, supply means for control fluid and two fluid flow sensors. The conduit is positioned to extend across the boundary so that its open ends are located on opposite sides of the boundary. The supply means introduces control fluid at an intermediate point so that control fluid flows through the conduit in opposite directions and discharges through both open ends. The fluid flow sensors are mounted so that each may sense variations in control fluid flow exiting at the ends of the conduit. These sensors generate output signals responsive to fluid flow across the boundary.
