Abstract
Abstract A solution cavitation creating device is located within a chamber having a liquid solution therein to create cavitation and a sound reflecting and suppression structure is located within the chamber to quiet the cavitation in the chamber and reflect the wave form into the liquid solution.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
155 words
An apparatus for agitating a liquid comprising: a housing defining at least one chamber for containing the liquid; cavitation generating means disposed within said at least one chamber for agitating the liquid contained in said at least one chamber; wave reflecting means disposed within said at least one chamber, said wave reflecting means including reflecting surface means located to reflect waves from generally the margin of said at least one chamber back into the body of the liquid contained in said at least one chamber to reinforce cavitation of the liquid in the chamber created by the cavitation generating means as the energy of the reflected waves is disipated in the liquid; sound suppressing, means disposed between said wave reflecting means and at least one wall of said at least one chamber to suppress or absorb the waves not reflected back into the liquid in the at least one chamber by the wave reflecting means.
Claim 2
Independent Claim
155 words
An apparatus for agitating a liquid comprising: a housing defining at least one chamber for containing the liquid; cavitation generating means disposed within said at least one chamber for agitating the liquid contained in said at least one chamber; wave reflecting means disposed within said at least one chamber, said wave reflecting means including reflecting surface means located to reflect waves from generally the margin of said at least one chamber back into the body of the liquid contained in said at least one chamber to reinforce cavitation of the liquid in the chamber created by the cavitation generating means as the energy of the reflected waves is disipated in the liquid; sound suppressing, means disposed between said wave reflecting means and at least one wall of said at least one chamber to suppress or absorb the waves not reflected back into the liquid in the at least one chamber by the wave reflecting means.
Claim 3
Dependent Claim
29 words
The apparatus of claim 1, wherein said wave reflecting surface means comprises a sheet of reflecting material disposed in adjoining relationship to at least one wall of said housing.
Claim 4
Dependent Claim
35 words
The apparatus of claim 1, wherein said wave reflecting surface means further comprises a sheet of reflecting material disposed in adjoining relationship to the bottom wall of said housing in said at least one chamber.
Claim 5
Dependent Claim
27 words
The apparatus of claim 3, wherein said sheet of reflecting material adjoining the bottom wall of said housing presents a curved reflecting surface to the vaporizing chamber.
Claim 6
Dependent Claim
13 words
The apparatus of claim 4, wherein said curved reflecting surface is generally convex.
Claim 7
Dependent Claim
162 words
A vapor generating and recovery apparatus comprising: a housing; means dividing the interior of said housing into at least two chambers for containing a liquid; heat emitting means disposed in at least one of said chamber for vaporizing a liquid contained therein; heat absorbing means disposed in at least one of said chambers for condensing vapor into said at least one chamber; means for transferring condensate from one chamber to the other of said at least two chambers; cavitation generating means disposed within at least one of said chambers for agitating the liquid contained therein; wave reflecting means disposed within said at least one chamber having said cavitation generating means, said wave reflecting means including reflecting surface means located to reflect wave from generally the margin of said at least one chamber back into the body of the liquid contained therein; and sound suppressing means disposed between said wave reflection means and at least one wall of said at least one chamber.
Claim 8
Dependent Claim
162 words
A vapor generating and recovery apparatus comprising: a housing; means dividing the interior of said housing into at least two chambers for containing a liquid; heat emitting means disposed in at least one of said chamber for vaporizing a liquid contained therein; heat absorbing means disposed in at least one of said chambers for condensing vapor into said at least one chamber; means for transferring condensate from one chamber to the other of said at least two chambers; cavitation generating means disposed within at least one of said chambers for agitating the liquid contained therein; wave reflecting means disposed within said at least one chamber having said cavitation generating means, said wave reflecting means including reflecting surface means located to reflect wave from generally the margin of said at least one chamber back into the body of the liquid contained therein; and sound suppressing means disposed between said wave reflection means and at least one wall of said at least one chamber.
Claim 9
Dependent Claim
43 words
The vapor generating and recovery apparatus of claim 6 further comprising: a refrigerant system; said means for condensing vapor being a refrigerant evaporator coil of said refrigerant sysytem; and said means for vaporizing liquid being a refrigerant condensing coil of said refrigerant system.
