Magnetic tape recording
Nov., 1958.]
BOOK NOTES
and Delrin resin are included. The treatment of polymerization systems for vinyl chloride is developed in considerable detail. Items such as vinyl laminates, regids, foamed material and latex paints, expected to show unusual growth, are clearly detailed. Here is a practical, informative text for manufacturers, fabricators and market developers. MAGNETIC TAPE RECORDING, by H. G. M. Spratt. 319 pages, illustrations, 5] )< 8½ in. New York, The Macmillan Company, 1958. Price, $8.50. Written especially for engineers who must be able either to build their own machines or to modify existing types, this volume is designed to cover the basic principles of magnetic recording and to enumerate the characteristics of both the medium and the machines. Chapters deal in principles of Magnetism and Magnetic Recording; Tape Recording Machines; Tape Testing; Recording Standardization and many other related topics. Two appendices on B. S. I. specifications and abnormal climatic effects are included, as well as an index. ELECTRIC MACHINERY, by Clifford C. Carr. 537 pages, illustrations, diagrams, 6 X 9 in. New York, J o h n Wiley & Sons, Inc., 1958. Price, $9.25. The approach used in this book is to establish the purpose of the machine, which is the conversion of energy. This is followed by an analysis of the feasible application of basic electric phenomena fulfilling the desired energy conversion. The text also discusses topics common to all electric machines: types of windings, voltage relations, magnetic-field relations, energy losses, energy flow, efficiency, ratings and basic torque relations. The remainder of the book is devoted to the application of these basic principles and a detailed analysis of the performance of the different types of machines. THE REPRODUCTION OF COLOUR, by R. W.
G. Hunt. 208 pages, plates, diagrams, 6{ >( 8½ in. New York, The Macmillan Co., 1958. Price, $12.75. The first half of this text covers the fundamental principles of photographic color reproduction, including television and printing.

Presented without mathematics, the book's object is to present problems of a visual nature to those engaged in producing color pictures. The second half provides a more rigorous and detailed discussion of general color reproduction problems and also particular fields of application. ELECTRONIC CIRCUITS, b y E. J. Angelo, Jr. 450 pages, diagrams, 6 X 9 in. New York, McGraw-Hill Book Co. Inc., 1958. Price, $9.00. This volume presents in considerable detail, the general techniques of developing piecewise-linear and incremental linear equivalent circuits, or network models, for physical devices. Modern circuit theory, augmented by certain new concepts which are directly related to the electronic devices, is used to develop a systematic theory for electronic circuits. The text provided some new approaches to many of the important topics in the study of electronic circuits. INFORMATION AND COMMUNICATION PRACTICE
IN INDUSTRY, edited by T. E. R. Singer. 304 pages, illustrations, 6 )< 9 in. New York, Reinhold Publishing Corp., 1958. Price, $8.75. In recent years, information-services groups have been playing a more important role in industrial communications. This handbook, prepared by a group of experts, sets forth the most efficient methods of dealing with the communications problem with particular reference to technical material. Chapters cover operations research, technical classification, research files, patent files, presentation of technical papers, punched-card methods, technical writing and editing, indexing and abstracting. The Editors wish to call attention to the series of mimeographed Nuclear Technology Briefs, prepared for and issued by the U. S. Atomic Energy Commission. Obtainable from the Division of Information Services, U. S. Atomic Energy Commission, Washington 25, D. C., the briefs provide American industry and science with authoritative (but by no means comprehensive) reports on important technological work as it emerges from research and development programs.
