Title: Ulrich Schulke: Innovator in Shadow Mask Technology

Introduction

Ulrich Schulke is a notable inventor based in Berlin, Germany. He has made significant contributions to the field of display technology, particularly in the development of shadow masks for color picture tubes. With a total of 2 patents, Schulke's work has had a lasting impact on the industry.

Latest Patents

Schulke's latest patents include innovative designs aimed at improving the performance of shadow masks. One of his patents is for a shadow mask with a porous insulating layer and a heavy metal layer. This design features a cathode-side surface that is covered with a heat-insulating layer, an electron reflecting and absorbing layer, and a heat-emitting cover layer. The technology allows some electrons to be reflected while others are absorbed and transformed into heat. Importantly, the heat does not act directly on the mask but is emitted into the interior of the tube, reducing local temperature differences that can cause partial doming of the perforated mask, especially with high contrast pictures.

Another patent focuses on a shadow mask that includes an insulating layer and a process for its production. This thermal insulating layer prevents heat transfer to the apertured shadow mask. The side of the mask directed toward the cathode is coated with a heat-insulating layer that contains particles with a porous structure. The pores may include heavy metals or heavy metal compounds, allowing for electron reflection and absorption directly within the layer. The heat generated is transferred to the interior of the picture tube rather than to the mask itself.
