Abstract
Abstract A vibration-transmitting member having large dimensions in planes perpendicular to the direction of vibration transmitted and adapted to be resonant in the sonic or ultrasonic frequency range is provided with internal bores to interrupt Poisson couplings between portions of such member. The bores are parallel to the direction of the vibration transmitted by the member.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
119 words
The combination of: an elongated vibration-transmitting member having an input surface and an output surface disposed at opposite ends; means disposed at said input surface for receiving a vibrationgenerating means for introducing high frequency standing waves in said member, the distance between said input surface and output surface being equal to an integral number of half wavelengths of the vibrations in said member so that antinodal regions of motion appear at said respective surfaces and at least one nodal plane therebetween, and said member having internal bores whose axes are disposed substantially parallel to the axis of the introduced standing waves and said bores extending across said nodal plane to interrupt Poisson couplings between the portions of said member.
Claim 2
