Apparatus and method for introducing high levels of vibratory energy to a work area

Claim 1

IN AN APPARAUTS COMPRISING MEANS FOR GENERATING VIBRATORY ENERGY, AN ACOUSTICALLY RESONANT TERMINAL MEMBER ADAPTED TO PERFORM USEFUL WORK, AT LEAST TWO FLEXIBLE RESONANT RIBBONS HAVING ANTINODES AT THEIR ENDS, ONE END OF EACH RIBBON BEING AXIALLY COUPLED TO SAID MEANS SO THA SAID RIBBONS VIBRATE IN A LONGITUDINAL MODE OF VIBRATION, MEANS CONNECTING THE OTHER AEND OF EACH RIBBON TO SAID MEMBER AT SPACED ANTINODE REGIONS ON SAID MEMBER, WHEREBY HIGH LEVELS OF VIBRATORY ENERGY MAY BE TRANSMITTED FROM SAID MEANS THROUGH SAID RIBBONS TO SAID MEMBER.

Claim 2

A METHOD OF PROVIDING MAXIMUM TRANSFER OF HIGH LEVELS OF VIBRATORY ENERGY THROUGH AN ANGLE WITHOUT ATTENUATION COMPRISING THE STEPS OF PROVIDING A VIBRATIONGENERATING MEANS AND A RESONANT WORK PERFORMINF ELEMENT SO THAT THEIR LONGITUDINAL AXES ARE NOT ALIGNED, PROVIDING AT LEAST TWO RESONANT FLEXIBLE MEMBERS HAVING ANTINODE REGIONS AT THEIR ENDS WHICH ENDS ARE COUPLED TO ONE OF SAID MEANS AND ELEMENT WITH A GOOD IMPEDANCE MATCH THEREBETWEEN, PROVIDING AT LEAST A PORTION OF SAID MEMBERS EXTENDED THROUGH AN ARCUATE PATH SO THAT THE BEND RADIUS OF EACH PORTION IS AT LEAST TO $/4 WHEREIN $ IS THE WAVELENGTH OF SOUND IN THE MATERIAL OF SAID MEMBERS AT THE OPERATING FREQUENCY, AND USING SAID FLEXIBLE MEMBERS TO TRANSMIT VIBRATORY ENERGY FROM SAID MEANS TO SAID ELEMENT.
