Abstract: An apparatus for treating a workpiece, the apparatus including a carriage for holding the workpiece, a first station for transferring the workpiece into and out of the carriage, a first chamber for holding treating fluid, a second station for transferring the workpiece between the carriage and the first chamber, and a mechanism for staging the carriage, the mechanism capable of positioning the carriage at the first station and at the second station and the first chamber capable of being isolated from atmosphere when the carrier is located at the second station.

Abstract: A treatment cell for spraying two phase treatment fluid on a continuously moving strip work product is enclosed within an air impervious containment chamber having ingress and egress openings to receive and discharge the work proudct. Air knives in the containment chamber receive air under pressure from a blower and this air strips any residual treatment fluid from work product at the chamber entry and egress openings. The air blower is within the chamber and the only air used through the air knives is continuously recycled entirely within the chamber. Cooling coils low in the chamber condense some of the vapor phase treatment fluid from the air in the container and all of the liquid phase of the treatment fluid flows by gravity to a sealed sump for reuse in the treatment cell.

Abstract: A method and an apparatus for depositing an inorganic phosphate coating on a metal substrate includes providing a first composition in a first bath having a high water and a high alcohol content and providing a second composition in a second bath having a low alcohol content positioned in proximity to the first bath so that vapors from the second bath are commingled with vapors from the first bath and the alcohol content of the second bath being such that the commingled vapors have an alcohol content that is not flammable.

Abstract: Flat metallic varnish-coated metal stampings or laminations to be deburred are conveyed by contiguous vertically aligned pairs of horizontal rollers across the top of a plurality of deburring cells or vats which are continuously overflowing with an electrolyte. Alternate cells are equipped with positively and negatively charged electrodes. The electrolyte is continuously supplied to each of the cells at a rate such that the electrolyte overflows the lips of each cell over which the lamination approaches and retreats from the cell. In this manner, the top surface of the electrolyte is maintained above the top surface of the lamination so that the electrolyte inundates at least the burrs on the edges of the lamination. Current flow from each positive electrode through the electrolyte, the stamped burred edges of the laminations and to the negative electrode causing the burrs on the laminations to be removed by anodic action.

Abstract: A dirty or otherwise contaminated volatile solvent or other treatment fluid including relatively more volatile non-flammable and relatively less volatile flammable constituents is recovered or reclaimed by boiling it off from its impurities. As the remainder is concentrated, the evaporated vapor becomes increasingly flammable. In a work process, a treatment tank is used for chemically treating work pieces in a volatile treatment fluid which has a liquid phase and a relatively non-flammable heavier-than-air vapor phase. In this process, heat energy is added to the fluid to maintain the upper vapor phase surface at a substantial distance above the upper liquid phase surface in the tank. When the treatment fluid becomes sufficiently contaminated with dirt introduced by the work pieces or otherwise, it must be removed from the tank and replaced with clean treatment fluid.
