Vibratory device for delivering vibratory energy at high power

Claim 1

IN A VIBRATORY DEVICE COMPRISING AN ELONGATED ACOUSTICAL COUPLING MEMBER HAVING FIRST AND SECOND ENDS, SAID ACOUSTICAL COUPLING MEMBER''S FIRST END HAVING A PLURALITY OF ARMS, SAID ACOUSTICAL COUPLING MEMBER BEING FOR TRANSMITTING MECHANICAL VIBRATORY ENERGY SUBSTANTIALLY IN THE LONGITUDINAL MODE OF VIBRATION FROM SAID ARMS OF SAID FIRST END TO SAID SECOND END, SAID ACOUSTICAL COUPLING MEMBER HAVING A PHYSICAL LENGTH SUBSTANTIALLY EQUIVALENT TO AN ACOUSTICAL LENGTH OF AN INTERGRAL NUMBER OF ONE-HALF WAVELENGTHS OF SOUND IN THE MATERIAL OF SAID COUPLING MEMBERS AT THE FREQUENCY OF OPERATION IN SAID LONGITUDINAL MODE, SAID ACOUSTICAL COUPLING MEMBER BEING CONSTRUCTED SO THAT ITS LARGEST TRANSVERSE DIMENSION LOCATED BELOW SAID ARMS IS SUBSTANTIALLY EQUIVALENT TO AN ACOUSTICAL DIMENSION NOT MORE THAN ABOUT ONE-QUARTER WAVELENGTH OF SOUND IN THE MATERIAL OF SAID COUPLING MEMBER AT SAID FREQUENCY, AND A PLURALITY OF MEANS FOR PROVIDING MECHANICAL VIBRATORY ENERGY TO SAID ACOUSTICAL COUPLING MEMBER, EACH OF SAID ARMS BEING ATTACHED TO SEPARATED SUCH MEANS, WITH THE MEANS ATTACHED TO EACH OF SAID ARMS BEING ADAPTED FOR PROVIDING MECHANICAL VIBRATION AT SUBSTANTIALLY THE SAME FREQUENCY AND IN SUBSTANTIALLY THE SAME PHASE, WITH THE INCLUDED ANGLE BETWEEN ADJACENT TWO OF SAID ARMS BEING LESS THAN ABOUT 76*.
