This book was released on 2016-10-14 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from An Efficiency Meter for Electric Incandescent Lamps The wattmeter should be calibrated to read correctly as a watt meter over the range for which it will be used, in order to avoid the necessity for applying a correction to the efficiency readings. It should have a compensating winding on the fixed coil, through which the potential current is carried in the opposite direction to the main current, so that the energy used in the potential circuit will not be measured along with that supplied to the lamp. This compensating winding is regularly supplied in low-range wattmeters by at least one well-known maker.

This book was released on 2016-10-13 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Guide to the Selection and Testing of Incandescent Lamps Central stations are in the business of making and selling light. They may sell by the ampere hour, the watt hour, the lamp hour, or by contract, but regardless of the way it is measured, the customer is in reality buy ing and using light. Since the lamp transforms the electrical energy of the generators into light, the best lamp is an absolute necessity to obtain the best light. It is, then, almost a self-evident truth that the exclusive use of the best lamp is the only means of obtaining the best results. The exclusive use of the best lamp involves two condi tions.

Download or read book Standard Lighting written by H. C. Cushing and published by Forgotten Books. This book was released on 2015-07-28 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Standard Lighting: With Incandescent Electric Lamps Since an Object is seen by the light which comes to it from the source and thence by reflection to the eye, it follows that color in the Object is seen only when the light contains rays Of that color. For example, a red Object will appear black under light in which red rays are lacking or a blue Object will appear black when blue rays are absent in the source. Daylight is composed of all the colors in proportions seen in the rainbow The light from Mazda lamps contains all the colors composing daylight but if the spectra, or rainbows, Of the two were to be compared it would be seen that the Mazda lamp was richer than daylight in the orange - red region and weaker in the blue. For ordinary purposes, the light from clear Mazda lamps is sufficiently like daylight to answer all requirements, but where color discr1m1nat10n is a factor, as in sorting or grading pro cesses for example, and in the laundry where scorch marks must be readily distinguishable, or where the artificial light is used to supplement daylight, as in an Office, daylight lamps, which screen out the majority Of the excess orange-red rays, find wide application.

Download or read book When Old Technologies Were New written by Carolyn Marvin and published by Oxford University Press. This book was released on 1990-05-24 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the history of electronic communication, the last quarter of the nineteenth century holds a special place, for it was during this period that the telephone, phonograph, electric light, wireless, and cinema were all invented. In When old Technologies Were New, Carolyn Marvin explores how two of these new inventions--the telephone and the electric light--were publicly envisioned at the end of the nineteenth century, as seen in specialized engineering journals and popular media. Marvin pays particular attention to the telephone, describing how it disrupted established social relations, unsettling customary ways of dividing the private person and family from the more public setting of the community. On the lighter side, she describes how people spoke louder when calling long distance, and how they worried about catching contagious diseases over the phone. A particularly powerful chapter deals with telephonic precursors of radio broadcasting--the "Telephone Herald" in New York and the "Telefon Hirmondo" of Hungary--and the conflict between the technological development of broadcasting and the attempt to impose a homogenous, ethnocentric variant of Anglo-Saxon culture on the public. While focusing on the way professionals in the electronics field tried to control the new media, Marvin also illuminates the broader social impact, presenting a wide-ranging, informative, and entertaining account of the early years of electronic media.
Download or read book The Culture of Energy written by Mogens Rüdiger and published by Cambridge Scholars Publishing. This book was released on 2009-05-27 with total page 279 pages. Available in PDF, EPUB and Kindle. Book excerpt: The culture of the modern world involves a sizeable and continuous use of energy. The story of energy as a part of modernity begins in the early 19th Century with hard work, experiments and the establishment of local energy systems. The natural conditions made certain by the alternation between light and dark, between warmth and cold, was gradually suspended by the introduction of electric lighting and heating into the home. The welfare state has significantly hastened this development to the degree that notions such as wellness and individual well-being have become natural elements of our consumer culture and our daily life. In most parts of the world we have light whenever we desire it, and the homes maintain a comfortable temperature of 21 degrees Celsius by use of either heating or of air-conditioning. In The Culture of Energy historians, social scientists and architects focus on various aspects of the energy culture in Western Europe, the United States, India and former Soviet Union, and examine subjects such as the history of lighting, street lighting, heating and central heating, household uses of energy, the debate on nuclear power, energy conservation and environmental perspectives on energy.
