Franz Knopf is a notable inventor based in Buhl, Germany, recognized for his contributions to emission technology. With a total of 14 patents to his name, he has made significant advancements in the field, particularly in high-voltage applications.

Latest Patents

Among his latest patents is the "Emission tip assembly and method for operating same." This invention pertains to an emission tip assembly on high-voltage electrodes designed for charging or discharging substrates. It features at least one emission tip and a carrier body made of insulating material, which includes a high-resistance series resistor. The design ensures safe handling while maintaining high efficiency, as the emission tip is constructed from spring metal, allowing for elastic spring action. Additionally, the invention improves the range effect of a discharge electrode by guiding auxiliary air directly to the corona tip.

Another significant patent is the "Impression roller and use of the same," which is intended for gravure printing with an electrostatic printing aid. This invention includes an axis member joined to a steel core, surrounded by an electrical inner insulating layer and an electrically semi-conductive outer layer. The roller is equipped with an encapsulated electric circuit that operates with low resistance during normal use and high resistance when the current flow direction is reversed.
