Abstract
1285715 Ultrasonic testing equipment JOHN THOMPSON Ltd 30 Oct 1969 [30 Nov 1968] 56942/68. Headings H4J and H4X An ultrasonic testing probe comprises an ultrasonic generator 10, a wedge 12, preferably of polymethylmethacrylate, and a lens 16, within which ultrasonic vibrations travel at a velocity which differs by at least 500 metres per second from the velocity with which the vibrations travel through the wedge. In one embodiment, the lens 16, Fig. 4, preferably of P.T.F.E. or water is of cylindrical planoconvex form positioned as shown, or the lens can be positioned (Figs. 1, 2, 3, not shown) with its axis of curvature at right angles to that shown in Fig. 4; thus the ultrasonic vibrations can be focused in planes at right angles to one another. In other embodiments, Figs. 5, 6, 7, and 8 (not shown), similar to above, a lens (17) or (18) is located on that side of the wedge adjacent to the ultrasonic generator 10. Simultaneous focusing in two planes at right angles can be achieved by having a pair of lenses, one on either side of the wedge. In a further embodiment, Fig. 9, a pair of lenses 22 and 23 are used, the lenses being formed of a material such as steel and of a cylindrical plano-concave form.
