Abstract

723,158. Ultrasonic inspection devices. SPERRY PRODUCTS, Inc. July 2, 1952 [July 7, 1951], No. 16645/52. Class 118 (2) [Also in Group XL (c)] The transmitted pulse from the generator 10 and the received echoes from the crystal 11 are fed to a circuit 15 (see Group XL(c)) which produces no output for an input of predetermined amplitude so that the transmitter pulse may be suppressed while echo signals 22, 23 are passed.
