Latest Patents
One of Andrew N Donham's notable patents is titled "Apparatus for inspecting can seams and the like." This invention focuses on detecting irregularities or flaws in seams, such as those found in cans. The apparatus utilizes a method of irradiating the surface of the seam to produce reflected radiation signals. It features a plurality of radiation sensors, each with a specific field of view, which generate output signals based on the reflected radiation they receive. The signal processing means then analyzes these signals to derive data representing the dimensional features of the seam. Additionally, the invention includes signal comparison means that assess whether the dimensional features fall within acceptable limits, producing a rejection signal if they do not. The apparatus also incorporates means for classifying the nature of any irregularities and transport means for moving seams through the sensor's field of view.
