Title
[PT032ACA1], Technical Note, Thomas Alva Edison, May 10th, 1889
Editor's Notes
9 page patent application draft labeled "US patent, Soak" Begins as follows: The object of this invention is to improve the methodsd of separating magnetic ores where the valuable maerial is either magnetic or non magnetic or both. [the file wrapper indicates that it was filed 890807 and after amendement it was allowed on 93070 but that Edison decided to forfeit it - might be worth seeing how it relates to caveat 114]
