Excerpt from The Bell System Technical Journal, 1923, Vol. 1
Modern industry is characterized by the extent to which scientific research and technique based on precise study have contributed to its progress. So complete has been the adaptation of and reliance on scientific research in many industries that it is difficult at this time to visualize the state of affairs of two or three decades ago, when substantially all industry on its technical side was dependent for advancement on cut-and-try, rule-of-thumb, methods of development. Today in many industries the management would not think of embarking on a new project without consulting their research engineers.
Many industries have proved the benefits to be derived from the utilization of that organized knowledge provided both in the fields of the physical sciences and in those newer fields which have to do with psychology and economics. There are still greater numbers of industrial organizations where the adoption of scientific methods has been slow. However, the time will undoubtedly come when every industry will recognize the aid it can derive from scientific research in some form as it now recognizes its dependence for motive power on steam or electricity rather than on muscular activity.

Paperback. Condición: New. Print on Demand. In this book, the author explores a new type of high-power vacuum tube capable of handling significant amounts of power. The development of these tubes was driven by the need for powerful vacuum tubes in wireless telegraphy and telephony. Prior to the invention of these tubes, the largest wireless stations used high-frequency alternators or arc converters. However, vacuum tubes offered several advantages over these methods, including the ability to modulate the output power to conform to the intricate vibration patterns of the voice. The author takes the reader through the challenges and innovations that led to the development of these high-power vacuum tubes, highlighting the work of Dr. E. R. Stoekle and Dr. O. E. Buckley. The book emphasizes the remarkable invention of a new type of vacuum seal that made these powerful vacuum tubes possible. This seal can withstand repeated heating and cooling over wide temperature ranges without cracking or impairing its vacuum-holding properties. The development of these high-power vacuum tubes had a significant impact on the field of wireless communication, enabling higher power and more efficient transmission of signals. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item. Nº de ref. del artículo: 9781330608005_0
