39456188, Mar 23, 1976

Filed:

Aug 1, 1974

Appl. No.:

5/493913

Inventors:

Andrew Shoh - Ridgefield CT

Assignee:

Branson Ultrasonics Corporation - New Canaan CT

International Classification:

B01F 1102

US Classification:

259114

Abstract:

This invention refers to an arrangement for providing vibratory energy to a liquid contained in an enclosure. The liquid is readily agitated and brought to cavitation by introducing sonic energy into a strip of metal in such a manner that the strip, being immersed in the liquid, exhibits flexural vibrations and thereby agitates the liquid.

Abstract:

A tubular resonator is coupled coaxially to a half wavelength extensional resonator at a nodal region of the vibratory motion in a direction parallel to the longitudinal axis of the extensional resonator. The frequency of the vibratory motion is in the sonic or ultrasonic frequency range, typically in the range from 1 kHz to 100 kHz. The radially directed vibratory motion at the nodal region of the extensional resonator is coupled to the tubular resonator and is converted by the tubular resonator into radial flexural vibratory motion which motion travels along the wall of the tubular resonator in a direction parallel to the longitudinal axis. A fluid within the flexural resonator thus is subjected to intense vibratory energy.
