This book documents and analyzes the existence of a strong, and growing, synergy between technological progress and the use of electrified production techniques in the United States during the twentieth century. The authors use two types of information in their work: case studies of the ways in which technological progress in particular industries and economic sectors has depended upon the adoption of electrified methods of production and aggregative long-term national economic statistics that measure the changing relationship over time between increases in the use of electricity and other factor inputs and the growth in industrial productivity. Eleven of the book's thirteen chapters cover the case studies, while the remaining two chapters and the statistical appendix contain the broad quantitative findings and supporting data.The system is automatic: its goal is to reduce the error signal to zero, when position adjustment ceases.9 During the ... sensing device or aquot;traceraquot; that required only very light contact with the master cam of a cam-following machine tool. ... Although actual cutting time was not necessarily less than that of conventional manual machine tools, overall production time was often reduced by more than 50 percent.
