Abstract

1,192,433. Piezoelectric transducers. INDUSTRIAL RESEARCH PRODUCTS Inc. 16 May, 1967 [17 May, 1966], No. 49215/69. Divided out of 1,192,432. Heading H4J. The Specification discloses the piezo-electric transducer described in the parent Specification, but the claims relate generally to a transducer having a pivoted lever interposed between the diaphragm and the transducer element.
