US Patent:

6818119, Nov 16, 2004

Filed:

Jun 14, 2002

Appl. No.:

10/172695

Inventors:

Guangxin Wang - Wexford PA
Daniel M. Hydock - Lower Burrell PA
John Lehman - Ellwood City PA

Assignee:

Honeywell International Inc. - Morristown NJ

International Classification:

C25C 100

US Classification:

205560, 205587

Abstract:

The invention encompasses a method and apparatus for producing high-purity metals (such as, for example, high-purity cobalt), and also encompasses the high-purity metals so produced. The method can comprise a combination of electrolysis and ion exchange followed by melting to produce cobalt of a desired purity. The method can result in the production of high-purity cobalt comprising total metallic impurities of less than 50 ppm. Individual elemental impurities of the produced cobalt can be follows: Na and K less than 0. 5 ppm each, Fe less than 10 ppm, Ni less than 5 ppm, Cr less than 1 ppm, Ti less than 3 ppm and 0 less than 450 ppm.

Filed:

Jul 6, 1998

Appl. No.:

9/109888

Inventors:

Rudolf Keller - Export PA
Brian J. Barca - Clairton PA
Daniel M. Hydock - Lower Burrell PA

International Classification:

C25F 100

US Classification:

205705

Abstract:

A method of electrolytically separating a paint coating from a metal surface comprising the steps of providing a metal member having a surface having a paint coating thereon and contacting the member with an essentially neutral electrolytic solution. The metal member is made cathodic in an electrolytic cell and current is passed from an anode electrode pad through the electrolytic solution to the metal member for a time sufficient to cause the paint coating to separate from the metal member. The pad is comprised of a first blanket for contacting the paint coating, a second blanket to cover the first blanket and an electrode mesh positioned between the first and second blankets.
