Abstract

1,132,125. Ultrasonic signalling apparatus. VUMA VYSKUMNY USTAV MACHANIZCIE A AUTOMATIZACIE. 2 May, 1966 [10 June, 1965], No. 19197/66. Heading G4F. [Also in Divisions H2 and H3] As shown in Fig. 1, optimum resonant conditions are maintained in an ultrasonic generator, which includes shaped transmission elements 2 of magnetostrictive material influenced by an electromechanical transducer 1, by positive feedback energization of transducer 1 through a variable gain amplifier 4 and a power amplifier 5 from a detector coil 3 arranged at the point of maximum stress in element 2. The gain of amplifier 4 is varied through an amplifier 6 by the output of coil 3 to compensate variations of feedback voltage. The exciting coil of transducer 1 is wound on a loop of magnetostrictive material to avoid coupling with coil 3. Elements 2 may be polarized by remanence, permanent, or electro-magnetism. Other combinations of magnetostrictive elements are described which are provided with detector coils at several points so that a suitable coil can be selected for control purposes.
