Abstract
Abstract The present invention provides an ultrasonic processor for the treatment, for example, dispersing, emulsifying, dissolving, mixing or deagglomerating of materials by the application of ultrasound thereto, wherein said ultrasonic processor comprises a hollow elongate enclosure member with a plurality of transducers fixed to the exterior of said elongate enclosure member along the length thereof; each said transducer being capable of applying ultrasonic waves to materials passing through the interior of said hollow elongate enclosure member; and control means for control and/or regulating the frequency of such ultrasonic waves produced by said transducers; and sensing means for the determination of the nature of the materials passing through the interior of said hollow elongate enclosure member, wherein said sensing means actuates said transducers to produce ultrasonic waves at the prescribed frequency in accordance with the nature of said materials to be treated. Furthermore, the present invention provides apparatus and methods for the separation of oil from drill cuttings and the separation of contaminants from soil materials.

Claim 3
Dependent Claim
31 words
An ultrasonic processor as claimed in claim 1, wherein the attachment means comprises at least one saddle-like member (105) which is adapted to receive at least one of said transducers (103).
Claim 4
Dependent Claim
47 words
An ultrasonic processor as claimed in claim 1, wherein the transducers (103) are arranged on the outer surface of the tubular member (101) in sets wherein each set comprises a number of transducers (103) arranged at the same height around the circumference of the tubular member (101).
Claim 5
Dependent Claim
20 words
An ultrasonic processor as claimed in claim 1, wherein the ultrasonic processor (8) is housed within a housing member (51).
Claim 6
Dependent Claim
23 words
An ultrasonic processor as claimed in claim 1, wherein the tubular member (101) has a diameter of between 2.54 cm and 25.4 cm.
Claim 7
Dependent Claim
36 words
An ultrasonic processor as claimed in claim 1, wherein the attachment member (105) is attached to the outer surface of the tubular member (101) by at least one of epoxy resin, silver soldering, and nickel brazing.
Claim 8
Dependent Claim
55 words
An ultrasonic processor as claimed in claim 6, wherein additional securement of the attachment member (105) to the outer surface of the tubular member (101) is effected by the use of retaining means (104) passing through the center of a transducer assembly (107) and are welded to the outer surface of the tubular member (101).
Claim 9
Dependent Claim
45 words
An ultrasonic processor as claimed in claim 1, wherein each transducer (103) includes a piezoelectric crystal which resonates at 30 kHz to 50 kHz and wherein each transducer (103) is resonated by an electric generator with an output power of between 1 and 12 kw.
Claim 10
Dependent Claim
