Title: The Innovations of Ernest N Schwenninger

Introduction

Ernest N Schwenninger is a notable inventor based in Cumberland, MD (US). He has made significant contributions to the field of glass manufacturing, particularly in the monitoring of glass surface temperatures during the annealing process. With a total of 2 patents, his work has had a meaningful impact on the industry.

Latest Patents

One of his latest patents is focused on a method and apparatus for continuously monitoring the surface temperature of a glass ribbon moving through a critical portion of an annealing lehr. This innovation is crucial as the rate of cooling determines whether the ribbon can be cut easily after annealing and whether it is at risk of spontaneous breakage. The temperature sensing means in this patent comprises a thermocouple junction embedded within a boron nitride plug, which slides in contact with the surface of the moving glass ribbon. This ensures that the main portion of the ribbon, which is cut into commercially acceptable glass blanks, maintains acceptable optical quality.

Another patent by Schwenninger also addresses the measurement of glass surface temperature during annealing. This method involves monitoring the surface temperature of a moving glass ribbon at a specific distance from the edge of the ribbon. Similar to his first patent, this innovation is vital for ensuring the ribbon's integrity as it moves through the critical portion of the annealing lehr.
