Abstract
Abstract This invention is an apparatus for transferring vibratorymechanical energy from an electromechanical transducer to a work surface by providing an intermediary impacting means which alternately contacts the work surface and the transducer. The intermediary impacting means is restrained for collinear movement by a flexible restraining means having a rigid support which is fixed to the nodal region of the electromechanical transducer.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
104 words
A combination for transferring sonic/ultrasonic vibratorymechanical energy to a work surface comprising a resonant piezoelectric vibratory-mechanical energy source, said resonant transducer including a force concentrator, means for electrically exciting said vibratory mechanical source at its resonant frequency, an intermediary impact device for transferring substantially all of said vibratory-mechanical energy to a work material, flexible restraining means for spatially positioning said impact device adjacent said force concentrator and for restraining said intermediary impact device to movement solely in directions collinear with the movement of said vibratorymechanical energy source, means rigidly fixed to the nodal region of said resonant source for supporting said flexible restraining means.
Claim 2
Dependent Claim
104 words
A combination for transferring sonic/ultrasonic vibratorymechanical energy to a work surface comprising a resonant piezoelectric vibratory-mechanical energy source, said resonant transducer including a force concentrator, means for electrically exciting said vibratory mechanical source at its resonant frequency, an intermediary impact device for transferring substantially all of said vibratory-mechanical energy to a work material, flexible restraining means for spatially positioning said impact device adjacent said force concentrator and for restraining said intermediary impact device to movement solely in directions collinear with the movement of said vibratorymechanical energy source, means rigidly fixed to the nodal region of said resonant source for supporting said flexible restraining means.
Claim 3
Dependent Claim
35 words
A combination as set forth in claim 1 wherein said resonant vibratory-mechanical energy source further comprises a half-wave vibratory-mechanical energy transmission line which is attached to said force concentrator end of said piezoelectric electromechanical transducer.
Claim 4
Dependent Claim
25 words
A combination as set forth in claim 1 wherein said intermediary impact device for transferring said vibratory-mechanical energy is a mass having a predetermined shape.
Claim 5
Dependent Claim
64 words
A combination as set forth in claim 1 wherein said means for restraining said means for transferring said vibratory-mechanical energy to movement solely in directions collinear with the movement of said source of said vibratory-mechanical energy is a plurality of flexible diaphragms securely attached to said means for transferring said vibratory-mechanical energy whereby ''''cocking'''' of said means for transferring said vibratory-mechanical energy is eliminated.
Claim 6
Dependent Claim
47 words
A combination as set forth in claim 1 wherein said means for restraining said means for transferring said vibratory-mechanical energy to movement solely in directions collinear with the movement of said source of said vibratory-mechanical energy further comprises a single diaphragm of sufficient thickness to prevent ''''cocking''''.
Claim 7
Dependent Claim
28 words
A combination as set forth in claim 1 wherein said rigid means for supporting said restraining means further comprises an enclosing structure thereby protecting the vibratory-mechanical energy source.
Claim 8
Dependent Claim
32 words
A combination as set forth in claim 1 wherein said combination further comprises means for subjecting said restraining means to a compressive bias force between the dynamic tool and the transmission line.
Claim 9
Dependent Claim
35 words
A combination as set forth in claim 1 wherein said combination further comprises means for subjecting said restraining means to an external bias force by which the dynamic tool is forced against the transmission line.
Claim 10
Dependent Claim
24 words
A combination as set forth in claim 1 wherein said combination further comprises means for maintaining said restraining means undeflected from the neutral position.
