Abstract
718,203 Piezo-electric instruments. BENDIX AVIATION CORPORATION. Feb. 21, 1952, [March 6, 1951], No. 4644/52. Class 40 (4). In an electro-mechanical transducer, the piezo-electric actuating element, which is bonded to a rubber front cap 21 for the purpose of transmitting vibrations to a fluid medium beyond, comprises a stack of polycrystalline ceramic elements 24 bonded together at their interface by conducting strip 25, alternative ones of which are commoned to form two sets of connections whereby an applied oscillatory current will cause the actuating element to vibrate longitudinally as an integral unit. In a second embodiment, Fig. 2 (not shown), the ceramic elements are circular and have holes therein to reduce the apparent density of the element. Specifications 583,639 and 601,477, [both in Group V], are referred to.
