Book Description
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.

Cables in the four horizontal ducts shown carry control pulses from the timing bay to the 12-channel group bays. These ducts are large enough in cross-section to handle all the cables required for a complete 96-channel terminal.

Book Description
Excerpt from The Bell System Technical Journal, 1941, Vol. 20 Whether sampling may be employed to advantage in place of 100% inspection usually depends, of course, on the purpose for which inspection is made. The sampling tables here presented provide definite procedures for conducting inspections that have certain immediate purposes which are described in some detail. Through their provision for instituting a screening inspection whenever quality falls below an acceptable level, the procedures have been found in practice to enforce a program of controlling quality in process as the alternative to high inspection costs.

Book Description
Excerpt from The Bell System Technical Journal, 1927, Vol. 6: A Journal Devoted to the Scientific and Engineering Aspects of Electrical Communication With the rapid development of electro-technics an increasing number Of problems is being encountered where the application Of classical electric circuit theory is Of doubtful validity, or where the conclusions derived from it must be interpreted with great care. Such problems are the result not only Of the use of very high frequency in radio transmission but arise also in connection with the need Of a more precise theory Of wire transmission.
