Abstract

There is presented a sonic apparatus for degassing liquids. The apparatus cludes a vessel for receiving and releasably retaining an open-top container and adapted to be closed with the container therein, transducer suspension structure positioned in the vessel, an ultrasonic transducer suspended from the structure and disposed in the container spaced from the walls and bottom of the container and beneath the surface of a liquid contained therein. The apparatus further includes a signal generator outside of the vessel for transmitting power to the transducer, and a vacuum pump for maintaining the vessel interior at a vacuum.

Claims

1. A sonic apparatus for degassing a liquid, said apparatus comprising:

a vessel with means to receive and retain the liquid, and said vessel is provided with means to receive and releasably retain an open-top container of said liquid, said vessel further being provided with means to be closed in a substantially gas-tight manner with said container therein, all of said liquid being in said container;

a transducer suspension structure positioned in said vessel;

an ultrasonic transducer suspended from said suspension structure and positioned in said vessel spaced from the walls and bottom of said vessel and positioned beneath the surface liquid in said vessel;

means for transmitting power from a signal generator assembly outside of said vessel to said transducer; and

vacuum pump means in communication with the interior of said vessel to maintain said vessel above the level of said liquid therein at a vacuum.

2. The sonic apparatus in accordance with claim 1 wherein said transducer is positioned in said liquid in said container and spaced from the walls and bottom of said container.

3. The sonic apparatus in accordance with claim 1 wherein said transducer is hung from said suspension structure by a transducer power line.
