Abstract: 1402210 Ultrasonic inspection devices; automatic gain control TSENTRALNY NAUCHNO - ISSLEDOVATELSKY INSTITUT TEKHNOLOGII MASCHINOSTROENIA 7 June 1973 27130/73 Headings H4D and H4R In a pulsed ultrasonic flow detector, the effect upon defect echo amplitude due to depth is removed by altering the gain of the receiver amplifier with time, a negative feedback circuit of the receiver amplifier being controlled by the voltage on a capacitor fed from a current generator employing positive feedback. An oscillator 1 passes ultrasonic pulses into the test object under control of a synchronizer 6. When an ultrasonic pulse is emitted, the synchonizer, via differentiating circuit 8, 9, switches on transistor 7. Capacitor 11, originally charged, is now discharged and transistor 7 is switched off again. Transistor 10 charges the capacitor and this causes transistor 14 to gradually become more conducting. Positive feedback via potentiometer 23 causes transistor 10 to become more conducting with time. Transistor 16 is coupled to a capacitor 19 and this transistor-capacitor combination is in parallel with the negative feedback resistor 21 in receiver amplifier 3. Transistor 16 becomes more conducting as capacitor 11 charges and hence resistor 21 in increasingly shunted by capacitor 19 with time, i.e. the gain of amplifier 3 increases. This gain increase cancels out the effect of depth on defect echo amplitude. In a further embodiment, (Fig. 2, not shown), resistor 21, transistor 16 and capacitor 19 are replaced by an F.E.T. (25) controlling the negative feedback introduced by a capacitor (26) coupled to the base of transistor 20 and feeding the signals from its collector back to its base via the F.E.T.
