Abstract

1,069,541. X-ray gauging apparatus. CORNING GLASS WORKS; Feb.11, 1965 [Feb.17, 1964], No.6034/65. Heading G1A. A cross-sectional area of an object is gauged by irradiating a reference object, of known dimensions and composition (this being the same as that of the object to be gauged), with a collimated X-ray beam, and detecting the unabsorbed portion of the beam to produce a first signal, irradiating the object to be gauged with a collimated X-ray beam and similarly obtaining a second signal, and comparing the first and second signals to give a difference representative of any difference in the cross-sectional areas of the two objects. The object to be gauged may be a rod, shaft or bar, or more particularly, glass tubing-being drawn during manufacture when the annular area of cross-section of the material of the tube is to be measured. In one arrangement Fig. 1, two beams from a source 11 are adjusted to be identical and each is collimated to be at least the width of the objects. The detectors 14, 16 ionization chambers, are connected to give a differential signal for indication on meter 17, which has previously been suitably calibrated, when the test object 13 and reference object 12 are in position. The reference object may be solid e. g. in the case of the gauging of glass tubing, a solid glass rod. The indicated signal represents the difference in the absorptions by the two objects. The meter is calibrated with measurements made on similar samples of known dimensions and of the same composition as the objects in values of cross-sectional area of the tube, inner diameter &c. The apparatus may be used in controlling the drawing rate of glass tubing, by using a reference object of a desired inner diameter, any deviation from this value in the test object being represented by a difference signal, from the detectors, which is used as the control signal. A modification of the apparatus Fig. 2 (not shown) involves a single radiation path, detector and meter. The meter is calibrated using a solid reference object e.g. a glass rod, of known dimensions and of the same material as objects to be gauged (glass tubes).
