Abstract

780,178. Holders for piezo-electric crystals. BENDIX AVIATION CORPORATION. Feb. 29, 1956 [March 8, 1955], No. 6360/56. Class 40 (8). [Also in Group XXXIX] At least one longitudinally vibratile cylindrical ceramic element 14 having electrodes on its end surfaces is mounted in a substantially solid casing 10 of rubber-like material, one electrode being bonded to a conductive surface layer forming a terminal 16 on a front diaphragm 22 and the other electrode being bonded to a rear electrical terminal 17. The front terminal 16 and a screening electrode 19 are connected to the outer conductor 12b of a cable 12, the inner high potential conductor 12a of which is connected to terminal 17. The electrodes on each element 14 are formed by painting with silver paint and baking to leave a thin film of silver. The electrodes are then cemented to the terminals 16, 17 which have previously been sand-blasted so that electrical contact is made through the cement. The device is mounted on the bottom of a ship, the front 10e of the device being pointed to reduce turbulence. The transducer is dimensioned to operate at a frequency of about 100 kc/s.
