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.
Claims16
A sonic apparatus comprising:
- a liquid;
- a wave guide dimensioned to undergo flexural vibrations disposed in said liquid, and
- means coupled to said wave guide for transmitting sonic energy to said wave guide for causing responsive to the propagation of flexural waves said wave guide to undergo flexural vibrations for producing vibrations in said liquid.
A sonic apparatus comprising:
- a liquid;
- a wave guide dimensioned to undergo flexural vibrations disposed in said liquid and having at least one end outside said liquid, and
- means coupled to said one end for transmitting sonic energy to said wave guide for causing responsive to the propagation of flexural waves said wave guide to undergo flexural vibrations for producing vibrations in said liquid.
A sonic apparatus comprising:
- a liquid bath;
- a source of energy dimensioned to resonate as a half wavelength resonator at a predetermined frequency of sound traveling longitudinally through said source and exhibiting when resonant at least two antinodal regions of longitudinal motion;
- a wave guide comprising a strip of metal of substantially rectangular cross sectional area having at least one end outside said bath and a portion immersed in said bath, and
- means removably coupling said one end of said wave guide to said source at a surface disposed substantially in a plane through one of said antinodal regions for causing said wave guide responsive to the receipt of energy from said source to undergo flexural vibrations which are transmitted into said liquid, said vibrations being the result of the propagation of flexural waves in said guide.
1 more element
The method for subjecting a liquid to high frequency sonic energy comprising:
- providing a liquid;
- immersing a wave guide in said liquid, and
- causing flexural waves to be propagated along said wave guide for causing said wave guide to undergo flexural vibrations and exhibiting a pattern of standing waves.
The method for subjecting a liquid to high frequency sonic energy comprising:
- providing a liquid;
- immersing one portion of a wave guide in said liquid while disposing another portion of said wave guide outside said liquid;
- coupling said another portion to a source of high frequency sonic energy for causing said wave guide responsive to said source being operative to undergo flexural vibration for exhibiting a pattern of standing waves, which waves cause vibrations in the liquid and said vibrations being the result of the propagation of flexural waves in said guide.
