摘要: An apparatus for applying a coating composition to an article and drying the solvent from the so applied coating prior to introduction of the coated article into the ambient atmosphere, comprising a housing or chamber in a generally "J" shape in which the small upwardly turned portion of the "J" defines an inner compartment isolated from the ambient atmosphere by the "J" configuration when the chamber is filled with a volatile solvent vapor and the inner compartment vapors are at an elevated temperature with respect to the remainder of the vapors in the chamber. The apparatus is provided with condensing means at the ambient atmosphere entrance and exit, a source of solvent vapors which may be integral with the chamber, and a means to introduce heat to the vapors and articles when they are in the inner compartment. The apparatus also includes article handling and moving means for transporting articles to be coated into, through and out of the apparatus as well as spray or dip means to apply the coating to the article.

摘要: A method for coating surfaces with organic film-forming compositions, which may contain pigments or coloring matter, characterized by applying the composition to a surface or substrate while subjecting the surface or substrate to a gaseous environment whose temperature is above the boiling point of the vaporizable solvent vehicle(s) of the coating composition and removing the solvent vehicle from the applied coating in a controlled manner while in said gaseous environment. The temperatures of the environment, the surface and the coating composition are selected relative one to the other such that the film of coating will gel yet not "skin over" until the solvent vehicle has been substantially completely removed from the coating, the solvent vehicle will not be substantially lost from the coating composition until the coating has been applied to the surface, or substrate, and the application of the coating to the surface or substrate will not materially cool the surface or the environment.

摘要: An improved method of impregnating wood with a preservative is achieved by using halogenated solvents as carriers for the preservative or other wood treating chemicals and removing the carrier from the treated wood by treatment with steam. Benefits derived from this process include fewer steps, substantially complete removal of solvent, and the production of a natural appearing wood product having a surface suitable for painting.

摘要: A method for dyeing polyester fibers by contacting the fiber, which may be in the form of loose fibers or staple, filament or texturized yarn, woven or knitted fabric, with a solution of a soluble dyestuff in a suitable solvent, such as a chlorinated solvent, reducing the volume of the solute in contact with the fiber while maintaining the volume of liquid in contact with the fiber substantially constant by addition of a nonsolvent, maintaining the temperature of the fiber and contacting solvent-nonsolvent at a temperature to effect dyeing. The process also includes the procedures for purifying the solvent and nonsolvent to enable their reuse (recycling) in the process economically and reducing the waste material from the process.The process also provides for scouring and/or drying the fiber if such be necessary.
