Abstract

1525781 Piezo-electric transducers TELEDYNE EXPLORATION CO 30 March 1976 [31 March 1975] 12656/76 Heading H4J A piezo-electric transducer, (insensitive to acceleration effects in hydrophones), comprises metallized piezo-electric wafers 10, 10′ with corresponding electrodes connected to flexible metal end faces 14, 141 (e.g. of Be-Cu, stainless steel or phosphor bronze) of a housing through which the other electrode terminations are hermetically sealed. Inserts 28, 32 prevent collapse under extreme pressure and the central housing portion may be of metallized glass. Two transducers are held in elastomeric members in a hydrophone streamer sleeve having perforated ends for oil flow.
