N-14-12-03 (1914)


This undated notebook is a continuation of N-14-04-26. It was probably used during the period August-October 1914. All entries are by Edison, except for several notations by another experimenter, possibly Frederick P. Ott. The entries pertain to experiments aimed at the rejuvenation or \"regeneration\"" of used storage batteries. Included are the results of tests performed on cells constructed with different regenerated components, primarily old negative electrode \""pockets\"" reconstructed with treated iron or formed using different crimping dies. There are also a few experiments that involve regenerated positive electrode \""tubes\"" made with treated nickel hydrate. Most of the experiments bear sequential numbers, 241E-382E. Some of the cells produced in these experiments were apparently transferred to the Edison Storage Battery Co. at Silver Lake for continued testing. Their subsequent performance is tabulated in N-14-12-14.1 (see Notebooks by Edison and Other Experimenters -- Storage Battery). Inserted into the book are two memoranda by Walter N. Archer and several loose pages of notes, probably by H. H. Smith. They date from the period August-December 1914 and relate to regenerated iron and nickel experiments being conducted for Edison. The front cover is labeled \""Regeneration No Two.\"" The pages are unnumbered. Approximately 160 pages have been used."
