Description

This notebook is a continuation of N-17-06-14.1. It was used by Edison in June-July 1917 to record research on amplification for the U.S. Navy during World War I. This work was probably done in connection with Edison\'s attempts at aiding submarine detection. There is also one entry by Isidor (Jerry) Chesler. Included are diagrams and descriptions of experimental amplifiers for detecting sound, along with notes regarding their performance. The components involved include audions, induction coils, batteries, condensers, phonoplexes, and mirror galvanometers. Some entries refer to work in earlier books in the series. A final entry summarizes the best amplifiers using one and two audions and concludes \"Now for a good Carbon Telefone.\"" The experiments are continued in N-17-00-00.8 The front cover is labeled \""U4.\"" The book contains 100 numbered pages; pages 94-100 are blank."
