  • Replenishment method for an advanced coating removal stripping solution
    Patent number: 7935642
    Abstract: A method for calculating the amount of solution components to add to an advanced coating removal (ACR) stripping solution in a coating removal stripping bath to replenish and recover stripping potential. The stripping effectiveness may be restored by the addition of only the primary acid of the composition of acids of the stripping bath and fresh water, in an amount necessary to restore the stripping solution to its original density.
    Type: Grant
    Filed: November 16, 2007
    Date of Patent: May 3, 2011
    Assignee: General Electric Company
    Inventors: Lawrence B. Kool, Gabriel K. Ofori-Okai
  • Method and etchant for removing glass-coating from metal wires
    Patent number: 7722779
    Abstract: An etchant for and method of removing a glass coating on a metallic wire is provided. The etchant comprises an acid solution having metal ions contained therein. The metal ions prevent the acid solution from pitting or damaging the metallic wire, while allowing the acid solution to effectively etch and remove the glass coating. In one embodiment, a fluorine-based acid solution can be used. In another embodiment, a glass coated, metal alloy microwire is etched and the metal ions added to the etchant are chosen to be the same as the majority constituent element in the metal alloy. The glass coating can be either removed in full or only partially removed.
    Type: Grant
