Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
75 words
A reactor for a chemical reaction, said reactor comprising: a vessel having a bottom and side walls, and an interior defined by said walls for containing the chemical reaction; at least one ultrasonic transducer facing into the interior of the vessel; and means for driving each ultrasonic transducer operably connected to each transducer; wherein each ultrasonic transducer is integral with at least one wall of the vessel; and, cap is positioned over each ultrasonic transducer.
Claim 2
Dependent Claim
75 words
A reactor for a chemical reaction, said reactor comprising: a vessel having a bottom and side walls, and an interior defined by said walls for containing the chemical reaction; at least one ultrasonic transducer facing into the interior of the vessel; and means for driving each ultrasonic transducer operably connected to each transducer; wherein each ultrasonic transducer is integral with at least one wall of the vessel; and, cap is positioned over each ultrasonic transducer.
Claim 3
Dependent Claim
31 words
The reactor as claimed in claim 1, wherein at least three ultrasonic transducers are integral with the bottom wall and at least six ultrasonic transducers are integral with the side walls.
Claim 4
Dependent Claim
75 words
The reactor as claimed in claim 1, wherein the bottom wall and side walls have an exterior surface and the reactor further comprising an external jacket surrounding the bottom wall and the side walls, means defining a passageway between the jacket and the exterior surface of the bottom wall and side walls, inlet means for transmitting a cooling or heating medium into the passageway, and, outlet means for transmitting said medium out of the passageway.
Claim 5
Dependent Claim
31 words
The reactor as claimed in claim 1, wherein at least five ultrasonic transducers are integral with the bottom wall and at least eight ultrasonic transducers are integral with the side walls.
Claim 6
Dependent Claim
19 words
The reactor as claimed in claim 1 wherein the means for driving each ultrasonic transducer is an ultrasonic generator.
Claim 7
Dependent Claim
20 words
The reactor as claimed in claim 5 wherein each ultrasonic transducer is operably connected to the ultrasonic generator via cables.
Claim 8
Dependent Claim
23 words
The reactor as claimed in claim 1 wherein the means for driving each ultrasonic tranducer includes means for independently driving each ultrasonic transducer.
