    Early in the history of our Government an office of weights and measures was established in connection with the Coast & Geodetic Survey for the purpose of providing suitable standards of length in connection with its work. At about the same time it became necessary for the Secretary of the Treasury to adopt standards of mass and capacity, and to provide copies of the same for use at the various custom-houses, thus increasing its functions to include mass and capacity. Later he was directed by the Congress to provide copies of these standards of length, mass, and capacity to the various states. This work was necessarily delegated to the office of weights and measures. Precision measurements of length necessitated the adoption and comparison of thermometic standards through the ordinary range of temperature. During the last years of the office of weights and measures it had begun in a very small way the testing of standards of electrical resistance and electromotive force, but owing to the limited facilities of the office its work was practically confined to the bare necessities arising in connection with the work of the Treasury Department. In urgent and important cases comparisons were made for other departments of the Government and for the public, although no provision was made directly for that purpose. In the meantime the scientific, manufacturing, and commercial interests of the country had assumed gigantic proportions. Accurate measurements were employed where before guesswork and rules of thumb were considered quite sufficient. Scientific work, and the introduction of scientific methods of manufacturing necessitated accurate methods of measurement. The dissemination of scientific knowledge and the adoption of the interchangeable method in manufacturing made the use of uniform working standards imperative, a result to be obtained only through primary standards of the highest type, and a central institution provided with the facilities for their compar- son with secondary or working standards.

  • The relation of railway sub-station design to its operation

    This paper is limited to a consideration of sub-stations in which high-tension alternating current is received and converted into low-tension direct current. In the operation of a modern railway converter sub-station, reliability of service is of paramount importance, being more important than considerations of first cost, of depreciation, and of maintenance; and in turn the reliability of service is affected to a marked degree by the length of time required to manipulate the various combinations of sub-station apparatus. The following factors will be noticed in this connection: 1. The best method of starting converters. 2. The protection of converters; 3. The use of oil-switches when synchronizing; 4. The regulation of load; 5. The best arrangement of switch-gear; 6. The operation of re verse-current relays; 7. The adjustment of load between the sub-stations which feed the same circuit; 8. The noiseless operation of synchronous converters. View full abstract»

  • Some considerations determining the location of electric railway sub-stations

    No attempt will be made in this paper to define the conditions under which indirect distribution, through the medium of transformer sub-stations, is more economical than direct distribution from one or more generating stations containing prime movers. It is assumed that because of the size of the railways to be considered, and the local conditions determining the cost of generating power, the indirect method of distribution has been selected as offering the best economy in commercial operation, and an attempt will be made to outline a general method for determining the number and location of sub-stations.

  • Discussion on lightning and lightning protective apparatus

    The subject of lightning and lightning protective apparatus, though of extreme importance, has unfortunately not received the attention it deserves. Most of us do not appreciate the amount of damage to property and the number of injuries and deaths caused by lightning discharges. We need more reliable information as to the nature of lightning and lightning discharges and the most effective method of protecting apparatus from these discharges. I regret that none of the papers takes up the subject of lightning striking things that are not electrical, such as buildings. I mention this because I think the public is usually misguided in the matter, many lightning rods that are worse than useless being sold to the credulous public. Engineers should at all times try to prevent the public from being imposed upon. View full abstract»
