Abstract: The present invention relates to methods and compositions for reducing corrosion and gassing that occurs within lead-acid storage batteries. In particular, combinations of anodic corrosion inhibitors such as hydrolyzed gelatin and water soluble iodides are preferred inhibitors; and these inhibitors provide excellent results when also used in combination with surfactants which are sodium salts of diphenyl sulfonate. Admixtures of anodic corrosion inhibitors, replace the conventional electrolyte solution within the battery.

Abstract: The present invention relates to an applicator for flowable materials which comprises a generally cylindrical housing having a chamber, a discharge opening, a wick projecting through said discharge opening, and a projecting structure for shielding the user from flowable materials and for preventing placement of the applicator in inappropriate receptacles. Further, the present invention relates to a storage and shipping rack for said applicators and to a method of dispensing flowable materials onto a surface. Preferably, the applicator is filled with metal coating and treating compositions such as aqueous acidic chromate compositions. Most preferably, the acidic compositions contain a very low concentration of a fluorinated surfactant.

Abstract: The present invention relates to an applicator for flowable materials to facilitate the repair of damaged metal coatings by allowing the user to quickly, safely, and accurately apply a metal coating solution to a specific portion of a metal surface, alleviating the need to re-immerse the entire metal item in a coating bath. This is particularly advantageous where the metal item is a portion of an automobile chassis or an aircraft which cannot be easily removed. Further, the applicator is a hand-held device which features a safety collar which protects the user from potentially harmful treatment solutions and, because the applicator enables the user to deliver metal coatings accurately and efficiently, chemical waste is essentially eliminated.

Abstract: Method and composition for applying a coating to a metallic surface, the surface being immersed in an acidic aqueous coating composition comprising dispersed solid particles of an organic polymeric resinous coating-forming material and an oxidizing agent, wherein the weight or thickness of the coating formed on the surface is a function of the time the surface is immersed in the composition.

Abstract: A process is disclosed for the removal of chrome from waste water containing chrome in addition to at least one chelating agent for trivalent chromium. The chrome-containing waste water is treated at low pH with both a reducing agent suitable for converting hexavalent chrome to trivalent chrome and with a ferric or aluminum sulfate or chloride salt. Following the reduction step, the pH of the now acidic solution is raised, using an inorganic base, to a pH sufficient to cause the formation of chromic hydroxide. The process of this invention is particularly suitable where rapid sedimentation processes, such as are achievable by the use of the lamella separator, are contemplated.

Abstract: A metallic surface is coated with a polymeric resinous coating by immersing the surface in an acidic aqueous coating composition comprising polymeric resinous coating-forming material and an oxidizing agent. The corrosion resistance and/or the surface appearance of the resinous coating is modified by rinsing the coating with an aqueous rinse solution containing hexavalent chromium or an aqueous rinse solution containing hexavalent chromium and reduced forms of chromium.

Abstract: Acidic aqueous coating compositions containing an organic coating-forming material form coatings on metallic surfaces which are immersed therein. The thickness or weight of the coating formed by the coating composition is a function of the time the metallic surface is immersed in the composition. The resulting coatings have adhesion properties thereby providing an adherent base to which other coatings, for example, paint primers and/or final finish paints can be applied.
