Title: Jeffrey S. Yigdall: Innovations in Glass Manufacturing

Introduction

Jeffrey S. Yigdall is an inventor based in Conneaut Lake, Pennsylvania, whose work addresses equipment and processes used in glass manufacturing. His patent portfolio includes 5 patents, with inventions focused on glass melting and the handling of float glass.

Latest Patents

“Glass Melting in a Rotary Melter” describes ways to control exhaust-gas circulation inside a heating vessel. By adjusting burner firing rates, adding jet burners, or changing burner angles, the system can direct gas flows to help reduce abrasive and corrosive effects on the vessel’s exposed interior surfaces.

“Edge Gripping Means for Attenuating Float Glass” concerns traction on a glass ribbon during the float-glass process. A freely rotating member, preferably a carbon cylinder, is pressed against the ribbon’s underside to improve traction, with the applied force regulated from outside the forming chamber.

Career Highlights

Yigdall’s patented work reflects practical engineering challenges in glass production, including protecting rotary-melter surfaces and improving control of a glass ribbon during attenuation. He is associated with PPG Industries, Inc., a company active in materials and glass technologies.

Collaborations

Yigdall’s listed coworkers include Yih-Wan Tsai and Robert A. Lawhon. Their shared professional context connects his work to broader technical efforts in glass manufacturing.

Conclusion

Jeffrey S. Yigdall’s inventions address key process and equipment challenges in glass production, from managing furnace exhaust flows to enhancing traction on float glass.
