Book excerpt: Excerpt from Thermionic Tubes in Radio Telegraphy and Telephony The thermionic vacuum tube or valve has, within the last few years, become such an important feature of wireless practice and development that modern radio communication may almost be said to be the application of this versatile device to the reception and transmission of wireless signals. The present book has been written with a view to providing in a single volume an account of the practical development of the vacuum tube and its innumerable applications. An attempt has been made to arrange the matter in a logical manner, and also to give historical details of interest. Every attempt has also been made to give references to the work of those who have developed the science by their inventions or scientific contributions. While writing from a practical experience of nearly all the matter contained in this volume, the Author has taken the fullest advantage of the work of others, with a view to making the book as comprehensive and detailed as possible. A great many references are given, and if any which should have been given are omitted it is due solely to the large size of the volume. In this connection, great difficulty has been experienced in allocating the credit for different developments on account of the absence of international exchange of information. Unless information is freely circulated by publication, misunderstandings as to the rightful credit for inventions are bound to arise. Nevertheless, the Author has made a thorough search of technical literature and patent specifications on the subject with a view to obtaining a correct perspective of the real work of development.

This book was released on 2015-06-28 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Thermionic Valve and Its Developments in Radio-Telegraphy and Telephony The present extensive use of appliances in modem radiotelegraphy and radiotelephony based on the thermionic emission from an incandescent cathode in a vacuous bulb, of which the Fleming oscillation valve was the first representative, has given rise to much published information on the subject in technical journals as well as to numerous patent specifications. Since most of the recent great advances in wireless telegraphy and telephony are dependent on the employment of these inventions it seemed desirable to collect together in a single volume some of this literature for the assistance of radio-engineers. The author, therefore, accepted the invitation of The Wireless Press, Limited, to write a small book on the practical side of the subject. It has not been deemed necessary to enter very fully into the purely scientific researches on thermionic emission from incandescent substances, because it has already been treated very fully by Prof. O. W. Richardson in his excellent monograph, The Emission of Electricity from Hot Bodies (Long-mans, Green & Co., London). The introductory chapter of the present volume, nevertheless, provides a brief sketch of the researches which led up to the practical applications described in subsequent chapters. The author has, however, felt it necessary to explain in rather full detail the history of this practical application by himself and others, and of the patent litigation which has taken place in the United States and in Great Britain in connection with it, on account of the efforts which have been made to depreciate the Author's work on this subject. The legal judgments in these actions are printed as an appendix, and will enable the reader to view the questions of priority of invention from the standpoint of unbiassed and competent judges. One other matter calls for remark, and that is the question of nomenclature. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Researches in Radio Telephony: A Thesis In the last few years the strides in radio telephony have been very rapid. About ten years ago the scientific world was first introduced to the fact that radio telephony was possible; but for the first few years following, the progress in this branch was comparatively slow due to the difficulties in the generation of high frequency currents of the undamped wave type. The only two ways it was found possible to generate currents of this nature was by the arc generator or by the high frequency generator; but in the last six or seven years a new type of generator has come into existance; namely, "The Hot Cathode Vacuum Tube." This generator practically revolutionized the entire field of radio telephony and to a lesser extent radio telegraphy; but had it not been for the war, it is rather doubtful whether our advance in this science in the last four years would have been quite as rapid as it has been.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Radio Telephony Since the publication of Dr. Erskine-Murray's excellent translation of Ruhmer's "Drahtlose Telephonie," there has appeared no complete exposition in any language, so far as the author is aware, of the important and growing field of radio telephony. The date of publication of Ruhmer's book was 1907, and in the succeeding decade advances have been made which render the methods there described obsolete. Accordingly the author has accepted the considerable task of writing a full description of the radio telephonic methods of the present in the thought that he might thus contribute to progress in that valuable art. Wherever possible, sufficiently complete descriptions of the apparatus employed have been given to enable the person skilled in the art to duplicate the results and to judge their value. In this connection, the ranges of transmission and the output power of the radiophonic stations have been presented. It has been thought, too, that the arrangement of apparatus in the set was of value in that it indicated how the various designers had attacked the problem of making radiophonic apparatus readily usable. It need hardly be stated that a good working knowledge of the methods and principles of modern radio telegraphy is necessary for the full appreciation of the material here set forth, though certain questions. common to both types of communication have been here considered in detail. The author desires to express his deep indebtedness for the valuable assistance in the form of information, illustrations, and diagrams which he has received from the following gentlemen and the organizations with which they are connected: Atlantic Communication Company and Messrs. Boehme, Brockmann and Reuthe; Compagnie Generale de Radiotelegraphie, and Lieutenants Colin and Jeance of the French Navy; Lieutenant W. Ditcham of the British Army; Mr. William Dubilier; Federal Telegraph Company and Mr. Leonard F.Fuller; General Electric Company and Messrs. E.F. W. Alexanderson, Albert W. Hull, and William C.White; Mr. W. Hanscom; Marconi Wireless Telegraph Company of America and Mr. Roy A. Weagant; National Electric Signaling Company and Mr. John L.Hogan, Jr.; Radio Telephone and Telegraph Company and Dr. Lee de Forest; Mr. Bowden Washington; Mr. Eitaro Yokoyama. Through their kindness he has been enabled to present here much important information and previously unpublished material. He also desires to commend highly the painstaking efforts of the editors of The Wireless Press to make this book measure up to the high aims of that organization.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The A B C of Vacuum Tubes in Radio Reception: An Elementary and Practical Book on the Theory and Operation of Vacuum Tubes as Detectors and Amplifiers; Explains Non-Mathematically the Fundamental Principles Upon Which All Vacuum Tube Circuits Are Based The inauguration of radio-telephone broadcasting has quickly aroused an enormous general interest in radio reception of speech and music. The possibilities of this new method of broadcasting information of general interest and entertainment can hardly be estimated. The method is revolutionary and has been aptly compared to the invention of the printing press in this respect. Vacuum tubes make possible the reception of radio-telephone speech and music and radio-telegraph signals with a degree of satisfaction not approached by prior devices. The vacuum tube appears to the layman as a complicated form of incandescent electric lamp which operates in a very mysterious manner. In writing this little book the author has endeavored to overcome this impression and to clearly set forth the elementary principles of theory and operation. It is assumed that the 'reader has no knowledge of radio and very little, if any, of electricity. Mathematics has been especially avoided in the treatment of the subject and no technical terms are used without their meaning being made clear.

Book excerpt: Excerpt from The How and Why of Radio Apparatus: A Treatise on the Principles Underlying the Operation of Wireless Transmitting, and Receiving Instruments; With an Appendix on Calculation and Measurement of Inductance In closing, the author would like to say that if the student wishes to become a thorough master of any specific subject, such as Radio telegraphy and telephony, that he not only should, but must, read all the different books on the subject which he can procure. If he cannot purchase them, then he can invariably procure them from the local library, or his friend's library. No one book covers everything, and if it did, you would not want it. There are too many changes and advances along certain specific lines, as for instance, in the Audion or vacuum tube field. If you want to know all about Audions, then by all means procure a book on that subject, of which there are several available. If you wish to go into the design of transformers, then you will save a great deal of time and misdirected effort by looking up specific books treating on this particular subject.

This book was released on 2015-07-03 with total page 418 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Thermionic Vacuum Tube and Its Applications In a comparatively short time the applications of Thermionics have grown to a considerable extent, and are now not only of great value in engineering fields, but are also penetrating more and more into university and college laboratories. It is difficult for those who are interested in the subject, but who have not had the opportunity or the time to follow its development closely, to abstract from the literature, which has become quite voluminous, the principles of operation of thermionic vacuum tubes. This and the popularity which the remarkable ability of these tubes to perform a great variety of functions has gained for them, have created a need for a book describing in a connected manner the more important phenomena exhibited by the passage of electrons through high vacua. In this work I have endeavored to set forth the principles of operation of thermionic vacuum tubes, and to coordinate the phenomena encountered in a study of this field. Such a procedure is sure to result in a more valuable book than a detailed description without proper coordination of the many investigations that have been published on this subject. I have tried to make the treatment sufficiently elementary to meet the demands that will necessarily be made on a book of this kind. This is especially the case with the first few chapters, which must be regarded as very elementary and are mainly intended for those who are interested in the applications of thermionic tubes but are not sufficiently acquainted with the properties and behavior of electrons to understand the operation of these tubes. I wish to express my indebtedness to several of my colleagues who have read parts or all of the manuscript. In this connection I wish to mention especially Mr. C. A. Richmond and Dr. P. I. Wold.
