  • Methods of evaluating the quality of two-dimensional matrix dot-peened marks on objects and mark verification systems
    Patent number: 8442297
    Abstract: Methods and mark verification systems for evaluating the quality of a two-dimensional matrix dot peen mark on an object are provided. An exemplary embodiment of the methods includes scanning a two-dimensional matrix dot peen mark disposed on a surface of an object with a laser displacement sensor to generate three-dimensional scanned data for the mark, the mark including a plurality of dots disposed in a plurality of rows and columns on the surface; and determining whether the mark passes a verification test based on the scanned data.
    Type: Grant
    Filed: February 23, 2010
    Date of Patent: May 14, 2013
    Assignee: Arinc Incorporated
    Inventors: Roger K. Tyler, Ronald D. Fowler

  • Power supply for electrochemical machining
    Patent number: 4004992
    Abstract: Method of electrochemical drilling of the type in which an insulating hollow electrode is positioned in closely spaced relation to an anodically charged workpiece and a cathodically charged electrolyte is passed through the electrode to impinge on the workpiece, utilizing a pulsating negative voltage on the electrolyte, the voltage having a substantial negative DC component and negative pulses superimposed thereon.
