  • Double seam monitor
    Patent number: 7736112
    Abstract: An apparatus for monitoring the quality of a double seam used in can manufacture, or can filling, to seam a can end (2) onto a can body (1). The apparatus uses a device (41) for measuring the strain/force applied by the lifter cam (10) so as to provide information such as first operation seam quality, gross seam defects and machine condition.

  • Gauge calibration
    Patent number: 7112972
    Abstract: A method of calibrating a gauge in particular for the measurement of film thickness, uses a calibration variable to compensate for short term changes in probe tip condition, instead of a constant value. A calibration constant is based only on the dielectric constant for a coating such as lacquer, and is independent of the probe tip variable.
