Abstract
Abstract This invention relates generally to electromechanical transducers having a high-Q and an improved structural arrangement capable of delivering from a source-and for given lengths-extremely high power outputs with only a minimum power loss. Specifically, the transmission of ultrasonic energy is through extended curved transmission lines. At the end of the transmission line opposite to that of the power source is coupled a work function utilization device. Theoretical data is correlated with actual data for different conditions in the transmission of ultrasonic energy through extended curved transmission lines.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
67 words
An electromechanical generator for imparting energy to a work surface comprising, a resonant piezoelectric transducer, a curved transmission line having a resonant length in half-wave equivalents to that of said transducer, and further having bends forming said curvature at the antinodes, means for joining one end of said line to said transducer at its output end, a work tool coupled to the opposite end of said line.
Claim 2
Dependent Claim
67 words
An electromechanical generator for imparting energy to a work surface comprising, a resonant piezoelectric transducer, a curved transmission line having a resonant length in half-wave equivalents to that of said transducer, and further having bends forming said curvature at the antinodes, means for joining one end of said line to said transducer at its output end, a work tool coupled to the opposite end of said line.
Claim 3
Dependent Claim
18 words
A generator as set forth in claim 1 wherein said work tool is intermittently coupled to said line.
Claim 4
Dependent Claim
24 words
A generator as set forth in claim 1 wherein the actual half-wave nodal points on said transmission line differ from the calculated nodal points.
Claim 5
Dependent Claim
28 words
A generator as set forth in claim 1 further comprising means for supporting said line and wherein said means are positioned at the nodal points on said line.
Claim 6
Dependent Claim
