Book Description
The necessity for a reprint of the previous edition of this Manual has afforded an opportunity of bringing the information in certain parts of the book up to date, by the addition of a new Chapter 13 which deals with the more important developments that have occurred in the interim. This method has been adopted in order to simplify and to expedite the preparation of the present edition. As with the other Manuals of the Series, the elementary method of treatment of the subject has been retained, but where considered necessary some theoretical aspects are discussed. The previous edition has been checked and where desirable certain minor altera tions and improvements have been made in order to clarify the text. There have been several important developments in electrical components and wiring methods since the last edition, the more interesting of which have included the wider use of electronics in the design and construction of certain automobile parts. Examples of these are the use of transistors, diodes and printed circuits on flat and flexible bases, notably for instrument panels, while minia turized versions of printed circuits are finding wider applications in automobile components, e.g. for alternator voltage control units. In order to assist the non-technical reader, for whom these Manuals were originally intended, a brief outline of the theory and applications of diodes and transistors has been included to help him to understand the circuits using these modern components.

Book Description
This book complements available one-make books on domestic synchronous clocks. It is also a history of science book that sets British domestic synchronous clocks, their manufacturers and technology in their social context. Part I covers the historical background, British domestic synchronous clock manufacturers and brands, how synchronous clocks work, domestic synchronous clock cases, practical advice on the servicing of domestic synchronous clocks and analysis of the marketing and reliability of British domestic synchronous clocks. This analysis provides an explanation of the rise and eventual fall of their technology. Part II contains galleries of a selection of British domestic synchronous clocks and of the movements with which they are fitted. There is a front and back view of each clock, together with a brief description. Views of each movement include views with the movement partly dismantled, together with a brief technical description of the movement. This profusely illustrated book is primarily for fellow enthusiasts and is based on an extensive archive of information on domestic synchronous clocks, their movements and their manufacturers. Current electrical regulations mean that professional clockmakers are reluctant to repair synchronous clocks. In fact, provided that they have not been mistreated, synchronous clocks are usually reliable, and quite easy to maintain.

Book Description
The history of the grid, the world's largest interconnected power machine that is North America's electricity infrastructure. The North American power grid has been called the world's largest machine. The grid connects nearly every living soul on the continent; Americans rely utterly on the miracle of electrification. In this book, Julie Cohn tells the history of the grid, from early linkages in the 1890s through the grid's maturity as a networked infrastructure in the 1980s. She focuses on the strategies and technologies used to control power on the grid—in fact made up of four major networks of interconnected power systems—paying particular attention to the work of engineers and system operators who handled the everyday operations. To do so, she consulted sources that range from the pages of historical trade journals to corporate archives to the papers of her father, Nathan Cohn, who worked in the industry from 1927 to 1989—roughly the period of key power control innovations across North America. Cohn investigates major challenges and major breakthroughs but also the hidden aspects of our electricity infrastructure, both technical and human. She describes the origins of the grid and the growth of interconnection; emerging control issues, including difficulties in matching generation and demand on linked systems; collaboration and competition against the backdrop of economic depression and government infrastructure investment; the effects of World War II on electrification; postwar plans for a coast-to-coast grid; the northeast blackout of 1965 and the East-West closure of 1967; and renewed efforts at achieving stability and reliability after those two events.

Book Description
"The Modern Clock: A Study of Time Keeping Mechanism; Its Construction, Regulation and Repair" by Ward L. Goodrich may seem like any of the countless manuals or technical works written about clocks over the years. As a delicate and complicated piece of machinery, having the most up-to-date information regarding its maintenance is of the utmost importance. However, Goodrich shows his expertise and ability to teach by providing readers with not only an informative text, but also one that is easy-to-understand and somehow still entertaining.
