Patent GB-799529-A (GB)
Title: Improvements in or relating to gauging apparatus
Inventor: LANCE THOMAS MARMADUKE CONSTAB
IPC: G01B11/02
Filed: 1955-07-22
Abstract: 799,529. Photo-electric gauging apparatus; television. RANK CINTEL, Ltd., [formerly CINEMA-TELEVISION, Ltd.]. July 23, 1956 [July 22, 1955], No. 21257/55. Class 40 (3). Automatic gauging apparatus comprises a television pick-up device scanning an area, an optical system to image the area in a focal plane, calibrated means for moving the focal plane normally to a surface to be located and means, for producing a desired operation, responsive to the television signal components arising only when the focal plane has a known relation to the surface. The basis of the invention is that the presence of the highest-frequency signals produced is critically dependent on the optical system being correctly focused on the scanned surface. In the first embodiment described (see Fig. 1 accompanying the Provisional Specification), motor 13 controlled by signals from pick-up tube 7 via amplifier 14, high-pass filter 15 and motor controller 16, moves carriage 6 such that when focal plane 8 of optical system 3, 4 meets the surface of cylindrical workpiece 1 to be gauged, the motor stops. Since the distance of plane 8 from surface 9 is predetermined the required workpiece radius can be obtained from a measurement by known means of distance of surface 9 from the workpiece centre line. For locating a concave surface a mirror system not described may replace the lens system. In a second embodiment (see Fig. 2) for gauging a flat surface 18 of a workpiece perpendicular to the optical axis and against a fiducial surface 20, the face of the pick-up tube is slightly inclined. The beam 22 of C.R. tube 21 is deflected vertically in synchronism with the scanning of the pick-up tube perpendicular to the line direction, and is deflected horizontally by signal amplitudes from a high-pass filter as above. Tube 21 carries graticule 23 showing the departure of the gauged dimension from nominal. The system is set-up by replacing workpiece 19 by a gauge block and traversing the optical system until the displayed signal coincides with graticule zero; the gauge block is replaced by another corresponding to one end of the graticule and the tube tilted to obtain coincidence of displayed signal and graticule end. In a modification (see Fig. 3, not shown) the field of view of the pick-up tube is in two vertical parts, one being the workpiece face image and the other an image of a fixed scale. Other types of pick-up tube may be used provided that the photo-sensitive and scanned surfaces are parallel. The flying-spot system may be used, the above pick-up tube being replaced by a scanned C.R. tube, light from the screen of which is projected upon the workpiece and light-sensitive means replacing the light source.
