Latest Patents

James Edward Nichols holds a patent for a "Rod and apparatus for calibrating magnetic roll testing apparatus." This invention features a calibration rod equipped with a grooved track and a testing apparatus designed for magnetic rolls. The apparatus produces an accurate homing location and probe-to-probe reference for repeated test verification at multiple testing locations. The grooved track calibration rod can be transported to different equipment to ensure consistent performance. It improves accuracy, incorporates temperature compensation, and utilizes a circumferential drive movement from one end of a roll magnet. This design verifies angular position from the opposite end, eliminating angular inaccuracies caused by twisting during clamping. A high-order polynomial curve fit of the data determines the true value of the Gauss level being measured during a 360-degree revolution. The apparatus accurately measures magnetic differences that define variations in probe operation, matching the values of other probes to a master reference probe while eliminating twist that can affect pole location accuracy.
