Patent number: 6576042Abstract: A method is taught for debubbling a liquid composition containing entrained gas bubbles that increases the effectiveness of ultrasonic debubbling apparatus employed. The method comprises the steps of immersing an ultrasonic horn in water, the horn being contained within a vessel and coupled to a pair of transducers; adjusting an RF generator connected to the pair of transducers to produce a signal at or near a parallel resonance frequency of the pair of transducers; fixing the RF generator at a constant voltage level; and flowing the liquid composition to be debubbled through the vessel with the RF generator operating at constant voltage level and at a variable operating power level that varies with the viscosity of the liquid composition.Type: GrantFiled: September 11, 2001Date of Patent: June 10, 2003Assignee: Eastman Kodak CompanyInventors: Robert P.

Patent number: 6502471Abstract: A method and apparatus for evaluating the end cap round transducer horn assemblies used in debubbling operations wherein the ECR THA can be evaluated off-line at both high and low power and on-line by making electrical measurements on the ECR THA. The electrical measurements are used to characterize the physical condition of the piezoelectric ceramics of the THA. A test box is employed to practice the method. The test box is connected between the THA and a signal analyzer. Power is supplied to the THA and the electrical signals across the THA are sampled. The sampled electrical signals are transmitted to the signal analyzer while maintaining the amplitude and phase relationship thereof. The sampled electrical signals are used to generate an impedance trace for the particular THA. That impedance trace is compared to a model impedance trace. In such manner, it can be determined whether the ECR THA is operational.Type: GrantFiled: January 5, 2000Date of Patent: January 7, 2003Assignee: Eastman Kodak CompanyInventors: Robert Peter Kraus, Jr., Fugui He, Roland J.
