Estimating the term…
A process and apparatus for ultrasonic cleaning of materials in which vibrating plates are used in close contact with a material to be cleaned. The material is placed in a shallow liquid and the vibrator of the plates eliminate dirt or contaminating substances from the material by cavitation of the liquid. The vibrating plates are flexurally vibrated at a frequency which correspond to its resonant frequency and is one of a sonic or ultrasonic frequency. The acoustic field created by the oscillation of the plates and in cleaning the material. A pledging system may also include ultrasonic vibrating plates to assist in expelling water.
A process for continuous ultrasonic washing of solid materials arranged in the form of sheets, strips, bands or layers having a large surface, and substantially unidimensional materials grouped together to form a band having a large surface, in a liquid medium, said process comprising:
