Abstract
718,260. Piezo-electric instruments. BENDIX AVIATION CORPORATION. Feb. 21, 1952, [March 6, 1951], No. 18976/53. Divided out of 718,203. Class 40 (4). In an electro-mechanical transducer for translating compressional waves in a fluid into electrical waves comprising an annular, radially-vibratile piezo-electric element 60 of polycrystalline ceramic having thin electrodes 60A, 60B on its inner and outer surfaces, the element 60 is closed at one end by a solid, sound or supersonic vibrationreflecting backing member 63 whilst the other end is open to the fluid medium. The transducer is enclosed in a fluid-tight casing 20 having a cap 21 of rubber with the same sound-transmitting properties as the liquid for which the transducer is designed, and the element together with the solid backing member 63 is surrounded in a mass of sound-insulating material 64. The space between the element and the front cap 21 is filled with a suitable, sound-transmitting fluid. In a modification, Fig. 2, four elements 60 are embedded in recesses 67 in a backing plate 63A so that the front face of the element is flush with the front face of the backing member. Specifications 583,639 and 601,477, [both in Group V], are referred to.
