Patent Number Title Of Patent Date Issued
6200529 Corrosion inhibition method suitable for use in potable water March 13, 2001
Effective corrosion inhibitors having minimal organic content, particularly suitable for use in municipal drinking water systems, are described. The preferred corrosion inhibiting additive is an aqueous solution of a stannous halide, preferably stannous chloride.
4581497 System for monitoring cathodic protection system of marine installations including an improved r April 8, 1986
An improved system for monitoring cathodic protection systems for marine installations wherein a reference electrode is utilized to measure and periodically monitor the cathodic reference potentials. The reference electrode is connected to one end of a cable and the opposite end portion
4477320 Method of preparing electrolytic manganese dioxide October 16, 1984
A method for the preparation of electrolytic manganese dioxide is provided employing improved cathodes, said cathodes being characterized by their reduced tendency to corrode and undergo buildup of current inhibiting scale under electrolytic conditions. The improved cathodes are fabricat
4413408 Method for fabricating electrodes November 8, 1983
This invention relates to a method for preparing an improved electrode comprised of titanium and platinum joined to one another in such manner as to resist separation by corrosion when utilized in a cathodic protection system in a corrosive environment such as in a shell and tube heat
4279705 Process for oxidizing a metal of variable valence by constant current electrolysis July 21, 1981
A process for oxidizing a metal of variable valence to a higher valence state by electrochemical means. More particularly, a process for oxidizing a metal of variable valence, such as, for example, uranium or vanadium contained in wet process phosphoric acid to a higher valence state for
4272343 Process for the electrolytic reductive leaching of ilmenite ore June 9, 1981
A process for beneficiating ilmenite ore using electrolytic reduction. The ilmenite ore is admixed with an acidic solution to form a mixture. The mixture is electrolytically reduced to convert at least a portion of any ferric iron that is present to ferrous iron. The acidic solution diss
