Title: The Innovative Contributions of Roger Perkins

Introduction

Roger Perkins is a notable inventor based in Baden-Rutihof, Switzerland. He has made significant contributions to the field of electrical engineering, particularly in the development of lightning arresters and voltage-dependent ceramic resistances. With a total of six patents to his name, Perkins has demonstrated a commitment to innovation and practical solutions in his work.

Latest Patents

Among his latest patents is a process for the production of a lightning arrester. This innovative device features a monolithic, active resistor core made from voltage-dependent resistance material based on zinc oxide (ZnO). The production process involves mixing and grinding base materials, creating pourable granules, and filling them into a silicone rubber tube. The granules are then pressed into a mold, sintered into a self-supporting resistor core, and finally converted with an insulator using various methods. The resulting lightning arrester is characterized by its simple configuration, good reproducibility, and cost-effective mass production.

Another significant patent by Perkins is the process for preparing a voltage-dependent ceramic resistance, or varistor, based on ZnO and other additive elements. This process includes adding compatible chemical substances to a suspension of ZnO powder, drying the mixture in a spray dryer, and pressing the resulting powder into a body. The pressed body undergoes heat treatment to decompose organic substances and convert them into oxides, followed by sintering at high temperatures. The use of water-soluble chemical substances, such as organic salts, enhances the effectiveness of the varistor.
