Today in 1951, US Patents 2546250 A and 2546251 A were issued, both inventions of Stanley L. Baker, for his “Process of Concentrating Yeast Slurries” and “Process for Drying Yeast.” There’s no Abstract for either, but the description for the first is an “invention relat[ing] to the concentration of dilute suspensions or slurries of yeast and especially of brewers yeast slurry which will be referred to hereinafter as an example although it will be understood that the invention is not restricted thereto.”
His second patent is described as an “invention relat[ing] to drying dilute suspensions or slurries of yeast and especially brewers yeast slurry which will be referred to hereinafter as an example, although it is to be understood that the invention is not restricted thereto.” You may have noticed that this description is exactly the same as the first. What’s clear is while these are two different patents, they are vey similar and are both about roughly the same yeast process. Even the drawings are only slightly different from one another.
I just wanted you to know that these were the patents of my grandfather, Stanley L. Baker. Thanks for this article.
