Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
102 words
A mechanical amplitude transformer adapted to receive vibratory energy at one end surface and provide vibratory energy of increased motional amplitude to a workpiece at an opposite end surface comprising: a first elongate metal member having a certain density; a second elongate metal member having a density different from that of said first member; a metallurgical bond joining said members to each other to provide a unitary assembly, and the composite length of said members being dimensioned for causing said transformer to be resonant as a half wavelength resonator at a predetermined frequency of the vibrations transmitted longitudinally through said unitary assembly.
Claim 2
Dependent Claim
102 words
A mechanical amplitude transformer adapted to receive vibratory energy at one end surface and provide vibratory energy of increased motional amplitude to a workpiece at an opposite end surface comprising: a first elongate metal member having a certain density; a second elongate metal member having a density different from that of said first member; a metallurgical bond joining said members to each other to provide a unitary assembly, and the composite length of said members being dimensioned for causing said transformer to be resonant as a half wavelength resonator at a predetermined frequency of the vibrations transmitted longitudinally through said unitary assembly.
Claim 3
Dependent Claim
27 words
A mechanical amplitude transformer as set forth in claim 1, said metallurgical bond being disposed substantially in the nodal region of longitudinal motion occurring in said transformer.
Claim 4
Dependent Claim
