Abstract
Abstract This disclosure relates to a laundry apparatus, papermaking apparatus or the like wherein the moisture in the wet laundry, paper slurry or the like, disposed therein is removed by an electrostatic means that provides a nonuniform field between the moisture in the laundry, paper slurry or the like and an electrode means to tend to cause the moisture to leave the laundry, paper slurry or the like and move toward the electrode means where the higher intensity portion of the nonuniform field is located. Such moisture removal operation can take place while the moisture-bearing material is being subjected to an inaudible scream and/or ultrasonic vibration, etc., to enhance the electrostatic moisture removal operation.
