  • Patent number: 6496448
    Abstract: A transducer member is made from a piezoelectric material (e.g. barium titanium) having a looped configuration and a gap in the loop and having properties of vibrating upon the introduction of an electrical voltage to the transducer member. A support member made from steel or aluminum and having a looped configuration and enveloping, and attached to, the transducer member has a gap aligned with the transducer member tap and has properties of vibrating with the transducer member. The transducer member may have a uniform thickness around its periphery or a progressively increasing thickness with progressive distances from the gap. The transducer has a high mechanical Q (e.g. 8-12) and a particular resonant frequency when disposed in air or in a vacuum. When the transducer is disposed below the earth's surface, its resonant frequency may vary because of variations in the earth's characteristics at the different positions.

  • Patent number: 6491095
    Abstract: A transducer provides (a) increased magnitudes of vibrations without cracking and (b) increased power to the transducer, in response to alternating voltages, for producing transducer vibrations with increased magnitudes. A polycrystalline ceramic (e.g. polycrystalline lead titanate or polycrystalline lead zirconate) has a looped configuration with a gap and has properties of vibrating upon an introduction of an alternating voltage, preferably rich in harmonies, to the ceramic. The ceramic is cryogenically treated as by initially reducing its temperature to approximately −100° C., then disposing the ceramic in liquid nitrogen and thereafter gradually increasing its temperature to approximately room temperature. This increases the dielectric strength of the ceramic by prestressing the ceramic, thereby providing for the ceramic to receive increased voltages without cracking. An alternating voltage rich in harmonics (e.g. square wave voltage) may be applied to the ceramic.

  • Patent number: 5592359
    Abstract: First and second units have similar, preferably substantially identical, constructions. Each unit is preferably cylindrical and has an outer electrically conductive shell preferably made from a metal. A dielectric material, preferably a ceramic, abuts the inner surface of the electrically conductive shell in each unit. A conductive coating is disposed on the inner surface of the dielectric material in each unit. In this way, each unit defines a capacitor with the shell and the conductive coating constituting the capacitor plates. The shell and the dielectric material in each unit have axially extending openings of matching dispositions. The units are disposed in abutting relationship with the openings facing each other. An alternating voltage is applied between the conductive coating and the conductive shell in each unit. This causes current to flow through the capacitor in each unit and to produce vibrations of the shell and the dielectric material in each unit.
