摘要:
A method and apparatus for non-destructively measuring the internal volume and nominal diameter of cylindrical or substantially cylindrical bores. The apparatus includes an expander with an expandable outer skin, the expander is configured to be inserted into the bore being measured. A fluid contained within a pump associated with the expander is forced into the expander. The fluid causes the skin to expand and press against the side of the bore being measured. The quantity of fluid required to press the expander skin against the bore is related to the internal volume and nominal diameter of the bore.
摘要:
A continuous edge of a strip of material is processed as it moves in a direction along the length of the strip. The condition of the continuous edge of the moving strip is inspected after it has been processed. The strip is cut into pieces. And the pieces are sorted into groups in response to the condition of the edge. The edge is continuously monitored by a pair of parallel, closely spaced laser beams. A visualization system includes a camera, a monitor, and a storage systems. The camera images an edge of the moving strip of material. The monitor, coupled to the camera, displays images captured by the camera. The storage system, coupled to the camera and the monitor, stores images captured by the camera. The monitor is capable of displaying the stored images.
