Apparatus for producing sonic and ultrasonic oscillations

Claim 1

APPARATUS FOR PRODUCING SONIC AND ULTRASONIC OSCILLATIONS OF A VIBRATORY BODY, COMPRISING, IN COMBINATION, AN ELONGATED VIBRATORY BODY HAVING AN AXIS AND WITHIN THE SONIC AND ULTRASONIC FREQUENCY RANGE TOGETHER WITH ANY MEMBER ATTACHED THERETO A PREDETERMINED RESONANT FREQUENCY FOR A PREDETERMINED MODE OF OSCILLATION AND INCLUDING A STATIONARY PORTION SUBSTANTIALLY COINCIDING WITH THE NODE OF SAID ELONGATED BODY WHEN IT OSCILLATES AT SAID PREDETERMINED RESONANT FREQUENCY AND MODE OF OSCILLATION AND A FREELY VIBRATABLE PORTION; HOLDING MEANS FOR STATIONARILY HOLDING SAID STATIONARY PORTION OF SAID VIBRATORY BODY WHILE PERMITTING SAID FREELY VIBRATABLE PORTION THEREOF TO OSCILLATE; FIRST MAGNETIC MEANS FIRMLY ATTACHED TO SAID FREELY VIBRATABLE PORTION OF SAID VIBRATORY BODY AND COMPRISING A PLURALITY OF MAGNETS EACH HAVING A NORTH AND SOUTH POLE AND ARRANGED SO THAT THE NORTH POLE OF ONE MAGNET IS DISPOSED NEXT TO THE SOUTH POLE OF THE ADJACENT MAGNET, SAID MAGNETS BEING IN A PLANE PERPENDICULAR TO SAID AXIS AND SURROUNDING THE LATTER, THE ORIENTATION OF THE MAGNETIC FIELD PRODUCED BY EACH OF SAID MAGNET MEANS BEING OPPOSITE TO THAT PRODUCED BY THE RESPECTIVELY NEIGHBORING MAGNET MEANS; SECOND MAGNETIC MEANS MOUNTED ROTATABLY ABOUT SAID AXIS AND ADJACENT TO SAID FIRST MAGNETIC MEANS INDEPENDENTLY THEREFROM AND FROM SAID FREELY VIBRATABLE PORTION OF SAID VIBRATORY BODY AND COMPRISING AN ASSEMBLY OF A PLURALITY OF MAGNETS SIMILAR TO THAT OF SAID FIRST MAGNETIC MEANS AND ARRANGED IN A PLANE PERPENDICULAR TO SAID AXIS AND SURROUNDING THE LATTER, THE ORIENTATION OF THE MAGNETIC FIELD PRODUCED BY EACH OF SAID MAGNET MEANS OF SAID ASSEMBLY BEING OPPOSITE TO THAT PRODUCED BY THE RESPECTIVELY NEIGHBORING MAGNET MEANS, SAID FIRST AND SECOND MAGNETIC MEANS COOPERATING IN SUCH A MANNER THAT WHEN SAID SECOND MAGNETIC MEANS IS PERIODICALLY CAUSED TO CHANGE BETWEEN MAGNETIC ATTRACTION AND REPULSION WITH SAID FIRST MAGNETIC MEANS IT CAUSES OSCILLATION OF SAID FREELY VIBRATABLE PORTION OF SAID VIBRATORY BODY; AND MEANS FOR ROTATING SAID SECOND MAGNETIC MEANS SO AS TO PERIODICALLY CHANGE IT BETWEEN MAGNETIC ATTRACTION AND REPULSION WITH SAID FIRST MAGNETIC MEANS AT SAID RESONANT FREQUENCY WITHIN THE SONIC AND ULTRASONIC FREQUENCY RANGE SO AS TO THEREBY CAUSE CORRESPONDING OSCILLATION OF SAID FREELY VIBRABLE PORTION OF SAID VIBRATORY BODY AT SAID RESONANT FREQUENCY.
