Title: The Innovative Contributions of Bret E Penrod
Introduction
Bret E Penrod is a notable inventor based in Toledo, OH (US), recognized for his significant contributions to the field of glass technology. With a total of 7 patents to his name, Penrod has developed innovative solutions that enhance the properties of glass, particularly in terms of its optical and thermal performance.
Latest Patents
Among his latest patents, Penrod has created a unique glass composition that absorbs infrared and ultraviolet light. This soda-lime-silica glass features a neutral tint and contains 0.3% to 0.7% by weight total iron, expressed as FeO. The formulation also includes specific amounts of selenium, cobalt oxide, and ferrous iron, ensuring a ratio of ferrous iron to total iron between 21 and 34. Additionally, nickel oxide and titanium oxide may be incorporated into the glass. The resulting product, with a nominal thickness of 4 mm, achieves a visible light transmission of at least 70% while maintaining a direct solar heat transmission that is at least 12 percentage points lower than the visible light transmission. Notably, the iron content is preferably derived from the inclusion of the mineral wuestite in the glass batch formulation.
Another significant patent involves a glass production method utilizing wuestite. This process outlines a glass batch composition for producing soda-lime-silica glass that contains iron oxides. The method includes the steps of admixing, heating, and melting a float glass batch mixture, where wuestite serves as at least a partial source of the iron oxides in the final glass product.
