Abstract
Abstract An ultrasonic fluid processing method is provided for cavitation and processing a first fluid with a second fluid in a sonication or cavitation zone. The method is useful for preparation of emulsions for chemical and pharmaceutical applications, to gasify liquids for purification, for chemical reactions, to accelerate chemical and physical reactions, and to suspend fine particles. The method includes the steps of, forming a vibration element having an axis and with an adjacent sonication or cavitation zone, enclosing the element and zone in a sealed cavity having a first fluid passage, forming a second fluid passage coaxially with the vibration element and disposed adjacent to the sonication zone, and forming a third fluid passage coaxially with the vibration element and disposed adjacent to the sonication zone. With this method, problems with the control of proportions and amounts and uniformity of parts of fluids being mixed or processed are avoided.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
80 words
An ultrasonic fluid processing method including the steps of: forming a vibration face with an axis for disposing a sonication zone adjacent to and coaxially with the vibration face; enclosing the vibration face and sonication zone in a sealed cavity having a first fluid passage; forming a second fluid passage coaxially with the vibration face and disposed adjacent to the sonication zone; and forming a third fluid passage coaxially with the vibration face and disposed adjacent to the sonication zone.
Claim 2
Dependent Claim
80 words
An ultrasonic fluid processing method including the steps of: forming a vibration face with an axis for disposing a sonication zone adjacent to and coaxially with the vibration face; enclosing the vibration face and sonication zone in a sealed cavity having a first fluid passage; forming a second fluid passage coaxially with the vibration face and disposed adjacent to the sonication zone; and forming a third fluid passage coaxially with the vibration face and disposed adjacent to the sonication zone.
Claim 3
Dependent Claim
26 words
The method of claim 1, including the step of: supplying electrical power and converting the electric power to ultrasonic sound waves for making the sonication zone.
Claim 4
Dependent Claim
34 words
The method of claim 2, including the step of: arranging the second fluid passage concentric about the axis and arranging the third fluid passage concentric about the axis and about the second fluid passage.
Claim 5
Dependent Claim
27 words
The method of claim 3, including the step of: adjusting a length of a dimension from the vibration face to an opening from the second fluid passage.
Claim 6
Dependent Claim
27 words
The method of claim 4, including the step of: adjusting a length of a dimension from the vibration face to an opening from the third fluid passage.
Claim 7
Dependent Claim
21 words
The method of claim 1, including the step of: forming a toroidally shaped assembly of openings from the second fluid passage.
Claim 8
Dependent Claim
22 words
The method of claim 1, including the step of: forming a pair of oppositely disposed radial outlet passages from the sonication zone.
Claim 9
Dependent Claim
25 words
The method of claim 1, including the step of: forming an annular opening from the second fluid passage coaxial and concentric about the sonication zone.
Claim 10
Dependent Claim
