  • Method for measurement of amount of liquid metal in casting furnace
    Patent number: 6125918
    Abstract: The invention relates to a method for measuring the amount of liquid metal contained in a tiltable casting furnace. A reference curve is established for the amount of metal contained in the furnace and the tilt angle of the furnace. This reference curve is established by first calculating a theoretical curve based on the geometry of the furnace and then correcting the theoretical curve based on the volume of metal used between one tilt angle and a greater tilt angle. The amount of metal contained in the furnace is read from the reference curve after the curve has been corrected for any deviation between actual metal level and reference metal level.

  • Detection of flaws in metal members
    Patent number: 4247306
    Abstract: A method of detecting flaws in metal members is disclosed. The metal member is exposed to high frequency heating whereupon the temperature profile across the work piece is measured, preferably by recording with an infrared camera. The recorded data can be used for automatic marking or repair of the metal member.
