Latest Patents
Among his latest patents, Pfeffer has developed a method of protecting metal against corrosion. This innovative approach includes a vehicle that features a structural member treated with a specialized coating. The coating contains refractory materials embedded in areas where the structural member is subjected to high temperatures exceeding 180 degrees Fahrenheit. These refractory materials, which are larger than 400 wire mesh in size, comprise 65 to 90 percent of the combined weight of the coating and refractory materials. Additionally, Pfeffer has patented a method of making a foam insulated vessel, such as a water heater. This method involves a tank designed to contain water and a jacket that is spaced outwardly to create a cavity. A band of self-supporting, gas-entrained, foamable resin is applied to either the outer surface of the lower end portion of the tank or the inner surface of the jacket. This band expands radially to form a closure that divides the cavity into isolated spaces, allowing for effective insulation.
