Abstract: 664,360. Echo-sounding. SPERRY PRODUCTS, Inc. June 25, 1948. [June 27, 1947] No. 17143/48. Class 118 (ii). In a pulse-echo system for detecting the presence of defects in materials, wherein supersonic pulses generated at G are transmitted into the material 11 under test and echo signals received from defects D in the material are indicated as variations in the current flowing through a meter M, means comprising a circuit L are provided for rendering the meter unresponsive to echo signals for a predetermined interval at an adjustable time after the transmission of an exploring pulse, so that the delay-time of an echo-signal, and thus the depth of the defect beneath the surface of the material may be determined. The receiver circuit comprises an amplifier A which is biassed off by pulse signals generated at K except during the interval between the transmitted pulse and the echo received from the opposite surface of the material so that the meter responds to echoes from defects within the material only. The circuit L produces a further pulse signal of adjustable duration and timing relative to the transmitted pulse and this signal is applied to a diode detector, Fig. 3 (not shown), feeding the meter M to bias the detector off and thus enable the time-delay corresponding to the defect to be determined. A further identical pulse generator L<SP>1</SP> may be provided so that more than one defect may be located at any one time. Specification 641,095 is referred to.
