Abstract
1,232,374. Mounting piezoelectric resonators. P. R. MALLORY & CO. Inc. 14 April, 1969 [19 April, 1968], No. 19045/69. Heading H1E. A radial-mode peizoelectric disc resonator 12 is gripped between resilient leads 14, 15 at a central nodal point in such a manner that it is free to rotate. The leads extend through the base 13 of a hermetic container from which extend a pair of integral stanchions 25, 26 which are provided with grooves 35, 36 for location of the leads 14, 15. In a modification (Fig. 3, not shown) two resonators are mounted in a single container between a pair of stanchions and on either side of an additional upright conductive member. The latter carries on either side protuberances each contacting a respective resonator at its nodal point and co-operating with a respective resilient lead to support the resonator.
