Investigating Or Analyzing Materials By The Use Of Ultrasonic Waves
(AREA)
Abstract
Ultrasonic sonar detector apparatus that uses the ultrasonic waves produced and received in a magneto-strictive transducer located in contact with water and protected by a hydro-dynamic part characterized by a high-frequency generator device constituted by two oscillating valves in symmetrical mounting in whose plate circuit a hybrid coil is located in an input circuit of reflected signals and amplification thereof formed by a pentodo valve as a voltage amplifier in an aperiodic circuit followed by two more stages of voltage amplifiers with tuned anode circuit and capacitive intervalvular coupling.
