Title: Ulf Rothgordt: Innovator in Electrophoretic Recording Technology
Introduction
Ulf Rothgordt is a notable inventor based in Norderstedt, Germany. He has made significant contributions to the field of electrophoretic recording technology, holding a total of 12 patents. His innovative work has paved the way for advancements in printing devices and methods.
Latest Patents
One of Rothgordt's latest patents is a printing device for electrophoretic recording. This invention involves a printing device that utilizes electrodes which are relatively movable with respect to an image carrier. A liquid developer fluid is present between the image carrier and the electrodes, allowing for effective recording under the influence of a control voltage. This technology enables point-like recording by ensuring that the surface of the image carrier is electrically conductive and that the developer fluid is continuously exchanged to maintain the supply of electrophoretic pigment.
Another significant patent is a method and apparatus for liquid electrostatic development of charge images. This method involves the simultaneous spraying of developer liquid in two flows directed towards each other on a tape-like record carrier. This results in two separate, uniform, and oppositely directed flow zones that meet at a common turbulent flow zone. The charge images are brought into contact with a large quantity of fresh developer liquid during both pre-development and final development stages.
