Abstract

726,330. Piezo-electric instruments. BENDIX AVIATION CORPORATION. Feb. 6, 1953 [Feb. 18, 1952], No. 3458/53. Addition to 718,260. Class 40 (4). In an electro-mechanical transducer for translating compressional waves in a fluid into electrical waves, comprising an annular, radially-vibratile piezoelectric element 24 as in the parent Specification, the backing member 36 has a planar front face spaced from the front face or window 34 of the casing, and sound-absorbing material is interposed between the outer circumference surface of the element and the cylindrical wall of the case. The casing comprises a cylindrical section 30 and a rear closure member 31 secured to make a fluidtight joint by screws 33. The sound or supersonic vibration-transmitting window 34 is set in a counterbore 35 and the ceramic elements 24 are positioned in holes 38a in a rubber of Corprene disc. The case is filled with oil through filler opening 45. Specifications 583,639 and 601,477, [both in Group V], are referred to.
