Patent number: 4942267Abstract: Decomposition of perchloroethylene is prevented by the addition of a stabilizer system containing N-substituted cyclic alkyl amine, alcohol of 3-7 carbon atoms and olefin components. The stabilizer system is advantageous in that it does not contain any environmentally undersirable materials.Type: GrantFiled: July 28, 1988Date of Patent: July 17, 1990Assignee: Occidential Chemical CorporationInventors: Roger W. Roark, Glenn R. Cairns, Edward A. Rowe, Jr.

Patent number: 4697043Abstract: Dielectric fluid is prepared by combining perchloroethylene with an aliphatic hydrocarbon having 7-9 carbon atoms in the aliphatic chain. The resulting dielectric has improved freezing point and nonflammability characteristics.Type: GrantFiled: October 1, 1986Date of Patent: September 29, 1987Assignee: Occidental Electrochemical CorporationInventor: Edward A. Rowe, Jr.
-
Patent number: 4425949Abstract: The removal of undesirable substances such as water, PCB's and air from the internal components of electrical devices such as transformers and power capacitors is efficiently and effectively achieved by contacting, in the absence of air, the internal components of these various electrical devices with a heat-stable fluid material. The heat-stable fluid materials are preferably halogenated aliphatic hydrocarbons and most preferably perchloroethylene or FREON 113.Type: GrantFiled: February 1, 1982Date of Patent: January 17, 1984Assignee: Diamond Shamrock CorporationInventor: Edward A. Rowe, Jr.
-
Patent number: 4293433Abstract: Electrical devices such as transformers and power capacitors are improved by the use of a dielectric fluid prepared by combining perchloroethylene having a low chlorinated ethane content with an antioxidant. This fluid has excellent resistance to decomposition over long periods of time and under severe operational conditions.Type: GrantFiled: June 2, 1980Date of Patent: October 6, 1981Assignee: Diamond Shamrock CorporationInventors: Jack A. Borror, Edward A. Rowe, Jr.

Patent number: 4186035Abstract: A chromium-containing treating composition, which is especially useful for rinsing phosphatized metal surfaces, contains hexavalent chromium-containing compound, methylene chloride and a substance that can be acetamide, N,N-dimethylformamide, acetone oxime and mixtures thereof. The composition is a homogeneous solution that is particularly useful where aqueous systems may create potential water pollution problems.Type: GrantFiled: October 16, 1978Date of Patent: January 29, 1980Assignee: Diamond Shamrock CorporationInventors: William H. Cawley, Edward A. Rowe, Jr.

Patent number: 4143205Abstract: Metal substrates, and particularly ferrous metal substrates, are now protected by having on their surface composite coatings wherein the base coating comprises a water-insoluble phosphatized coating from an organic phosphatizing composition. Over the phosphatized base coating there is then deposited a topcoating that is typically a paint topcoating. However, a rinse coating, such as a chromic acid solution, may be used on the base coating prior to a paint coating. A highly desirable adherent, corrosion-resistant and water-insoluble composite coating thereby protects the substrate metal.Type: GrantFiled: December 27, 1977Date of Patent: March 6, 1979Assignee: Diamond Shamrock CorporationInventors: Edward A. Rowe, Jr., William H. Cawley

Patent number: 4118253Abstract: A liquid phosphatizing composition, containing organic solvent such as 1,1,1-trichlorethane or trichlorofluoromethane, can provide phosphate coatings on metal articles. In addition to the organic solvent, the composition contains a phosphatizing proportion of phosphoric acid and a solubilizing liquid capable of solubilizing phosphoric acid in the organic solvent. The composition contains a minor amount of water, yet it is an amount exceeding the proportion of phosphoric acid, and the composition is non-flammable. Phosphatized coatings of desirable water insolubility are obtained.Type: GrantFiled: December 30, 1976Date of Patent: October 3, 1978Assignee: Diamond Shamrock CorporationInventors: Edward A. Rowe, Jr., William H. Cawley
-
Patent number: 4102710Abstract: Topcoat adhesion is now increased for coatings applied over a solvent phosphatized metallic surface. The phosphatized surface is obtained from a composition that can contain methylene chloride, as well as water in minor amount, and yet maintain a continuous and homogeneous liquid phase. By adding significant amounts of stabilizer to the phosphatizing composition, generally by way of an adjuvant composition, the resulting phosphatized coatings will provide for enhanced topcoat adhesion.Type: GrantFiled: December 22, 1976Date of Patent: July 25, 1978Assignee: Diamond Shamrock CorporationInventors: Edward A. Rowe, Jr., William H. Cawley

Patent number: 4073066Abstract: A liquid composition, containing methylene chloride, can provide phosphate coatings on metal articles. In addition to the methylene chloride, the composition contains a phosphatizing proportion of phosphoric acid and a solubilizing solvent capable of solubilizing phosphoric acid in methylene chloride. Most critically, the composition contains water in an amount exceeding the proportion of phosphoric acid, yet, the water-containing liquid composition maintains liquid phase homogeneity. Phosphatized coatings of desirable water insolubility are thereby obtained.Type: GrantFiled: June 7, 1976Date of Patent: February 14, 1978Assignee: Diamond Shamrock CorporationInventors: Edward A. Rowe, Jr., William H. Cawley

In addition to the methylene chloride, the composition contains a phosphatizing proportion of phosphoric acid and a solubilizing solvent capable of solubilizing phosphoric acid in methylene chloride. Most critically, the composition contains water in an amount exceeding the proportion of phosphoric acid, yet, the water-containing liquid composition maintains liquid phase homogeneity. Phosphatized coatings of desirable water insolubility and unique characteristics are thereby obtained.Type: GrantFiled: July 28, 1976Date of Patent: January 24, 1978Assignee: Diamond Shamrock CorporationInventors: Edward A. Rowe, Jr., William H. Cawley

Patent number: 4056409Abstract: Topcoat adhesion is now increased for coatings applied over a solvent phosphatized metallic surface. The phosphatized surface is obtained from a composition that can contain methylene chloride, as well as water in minor amount, and yet maintain a continuous and homogeneous liquid phase. Resulting phosphatized metallic surfaces are often topcoated. By adjusting the constituency of the phosphatizing composition, such as by augmenting the water content, topcoat adhesion can be markedly enhanced.Type: GrantFiled: July 28, 1976Date of Patent: November 1, 1977Assignee: Diamond Shamrock CorporationInventors: Edward A. Rowe, Jr., William H. Cawley
