Paperback. Etat : 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. N° de réf. du vendeur 9781330608005_0
