  • Arc treatment of metal surfaces
    Patent number: 5674416
    Abstract: A method and apparatus for graining a surface having a substantial area traveling at a substantial rate of speed. The method includes directing the surface past an array of electrical arcs traveling about a plurality of loop electrodes arranged to provide overlapping arc loop paths as the surface travels past the array of arc loops. The arc loops are established between the loop electrodes and the traveling surface, and thus contact the surface to grain the same. When each arc is struck between its loop electrodes and traveling surface, it is magnetically impelled about the loop of its electrode by a magnetic field established perpendicular of the direction of arc current flow. An annular sheath of gas is provided on each side of the electrode loop and the arc struck between the electrode loop and the traveling surface.

  • Apparatus and method of non-destructively testing ferromagnetic materials including flux density measurement and ambient field cancellation
    Patent number: 5122743
    Abstract: Apparatus for measuring flux density within the surface of a ferromagnetic material (24) includes a probe (10) having an end for location on or adjacent the surface of the material (24), a first sensor at the said end of the probe (10) and capable of producing a first output signal representative of the strength of the magnetic field to which said first sensor is subjected, and a second sensor at the remote end of the probe (10) and capable of producing a second output representative of the strength of the magnetic field to which said second sensor is subjected. An electronic circuit produces a difference signal representing the difference between the first and second outputs, and an output device (14) displays and/or records said difference signal (16).

  • Method and apparatus for reducing magnetic field strengths in welding zones
    Patent number: 4761536
    Abstract: Apparatus for reducing the strength of magnetic fields in a vicinity of weld zone in a workpiece to be welded includes a Hall effect sensor for sensing the strength of the resultant magnetic field in the weld zone vicinity, and a magnetic field generator responsive to the output signals from the Hall effect sensor to generate a counterbalancing magnetic field in the weld zone vicinity so as to reduce the resultant magnetic field in the weld zone vicinity.
