ACOUSTIC LIQUID PROCESSING DEVICE
An acoustic liquid processing device in the form of a vessel (12) having an interior wall which surrounds a process liquid (14). A transducer (13) having an acoustic impedance approximately equal to that of the process liquid (14) is attached to the interior wall to substantially envelop a selected...

| description | An acoustic liquid processing device in the form of a vessel (12) having an interior wall which surrounds a process liquid (14). A transducer (13) having an acoustic impedance approximately equal to that of the process liquid (14) is attached to the interior wall to substantially envelop a selected volume of the process liquid (14). The transducer is preferably an electrostatic film transducer. The transducer is energized to subject the process liquid to acoustic vibration.
Dispositif d'usinage par ultrasons en milieu liquide se présentant sous la forme d'une enceinte (12) dont la paroi interne entoure le liquide d'usinage (14). Un transducteur (13) présentant une impédance acoustique à peu près voisine de celle dudit liquide (14) est fixé à la paroi intérieure de façon à en englober un volume donné (14). Lors de sa mise sous tension, le transducteur, de préférence du type à film électrostatique, reçoit de l'énergie qu'il transmet au liquide d'usinage sous forme de vibrations acoustiques. |
