Title: Process and Apparatus for the Ultrasonic Inspection of Materials
IPC: G01N29/30
Filed: 1967-08-07
Abstract: 1,199,177. Ultrasonic inspection devices. DR. J. U. H. KRAUTKRAMER GESELLSCHAFT FUR ELEKTROPHYSIK. 7 Aug., 1967 [6 Aug., 1966; 23 Dec., 1966], No. 36178/67. Heading H4D. In a system for the ultrasonic inspection of a workpiece by the pulse-echo or through-transmission method, an electrical pulse is induced by the entry of ultrasonic energy into the workpiece. This pulse provides an accurate time "zero" for measuring the transit time of an ultrasonic pulse to a discontinuity or the bottom face and back, and its amplitude indicates the acoustic coupling efficiency of the transmitter probe to the workpiece. In the Fig. 14 embodiment transmitting/receiving transducer 11 is coupled to workpiece 13 by a delay column 12 of electrically insulating material. The workpiece, or at least a surface coating thereon, is electrically conductive so that particle motion caused by ultrasonic energy in the surface region induces an electrical output pulse from a coil or coils 26 in the field of magnet 25 or of an electromagnet. This pulse is displayed on monitoring oscilloscope 6a and on a flaw detection oscilloscope coupled to transducer 11, can be used to operate, through gate amplifiers, flaw warning devices and recording apparatus and can be further used to maintain constant the flaw detection sensitivity. When measuring the thickness of thin-walled workpieces, the induced pulse can be separated from the bottom face echo in the display by passing the transducer 11 echo signals through an electrical delay. For appropriate workpieces the induced pulse may be produced by the magnetoelastic effect instead of by electromagnetic induction. Modifications of the coil 26 arrangement are described for use with shear wave inspection of the workpiece.

Abstract: 915,006. Electrochemically polishing elongated metal articles. BROOKS (OLDBURY) Ltd. Oct. 23, 1961 [Oct. 25, 1960], No. 36559/60. Class 41. Elongated metal articles such as tubes or bars are electrochemically polished by a cathode element which is adjustable about an axis which extends transverse to the longitudinal axis of the metal article. Figs. 1 and 2 show an anodic tube or bar 10, a cathodic tool 12, and an electrolyte supply pipe 18. The tube or bar can be advanced axially and rotated about its axis at speeds suitable for the metal removal. The cathodic tool 12 can be moved towards or away from the tube or bar by a piston-and-cylinder unit 13 and can be angularly adjusted relative to the tube or cylinder by a piston-andcylinder unit 15, thereby varying the rate of removal of metal from the tube or bar and also varying the effective operating area of the cathodic tool. More than one cathode element may be provided. Fig. 3 shows an embodiment for use with a workpiece 19 having an axial and rotational speed which are governed by some other operation, e.g. drawing, where the speed is not suitable for the electropolishing. In this embodiment, a cathode tool 21 is mounted in a head 22 which is rotatable by a motor 23 through gearing 24 and is axially movable by a screw 25. The tool is again movable towards and away from the workpiece by a unit 26 and is angularly adjustable by a unit 27. In addition, a motor 8 rotates the tool about its own axis. Fig. 5 shows an embodiment for polishing the interior of a tube 28. A cathode tool 29 is carried by a cage 30 supported by bags 31 inflatable through tubes 32. By inflating one bag more than the other the tool can be tilted with respect to the tube 28 and by rotating one tube 32 relative to the other the cage and tool can be twisted relative to the tube 28. Centring and steadying units 33 for the cage may be provided. Fig. 8 shows an embodiment for use with a tube whose axial and rotational speeds are controlled by some other operation. A cathode tool 36 mounted on a cage 38 is rotatable about its own axis by a flexible drive 37. The two ends of the cage are relatively rotatable by a rod 39 and tube 40. The resultant twisting of the cage angularly adjusts the position of the cathode tool 36. According to the Provisional Specification, a cathode of circular cross-section, mounted by a cage-like structure within a tube, may be rotated about its own axis and also about the tube axis.
