Book excerpt: Excerpt from The Manufacture of Electric Light Carbons Conductivity is of the greatest importance: the greater the facility with which the current passes, the better the light and the less the required. Thus I think I may state, without experimental data to go upon, but by observation only, that a candle of high conductivity will give as good a light with a 6-ampere current and 38 volts as one of lower conductivity using 42 volts and 8 amperes. Indeed, when the conductivity is very low, the current will not produce the arc, and the carbon becomes intensely heated. This conductivity depends entirely (given pure carbon) on the length of time to which it has been submitted to the firing process. Graphite appears to owe its peculiar condition of high conductivity to its lengthened subjection to Nature's forces, unapproachable by human efforts. Great pressure, continuous and intense heat protracted over long periods, even if possible, would prove commercially im practicable; yet I entertain no doubt that carbon submitted to a white heat, such as would melt wrought iron, for a whole week, would produce a candle more graphitic in character and possessing higher conductivity than one that had been subject to such treatment for a less period. As I deal with the subject of firing, and my special economic arrangements for so doing, this subject will be more fully dealt with.

Book excerpt: In September 1878, Thomas Alva Edison brashly—and prematurely—proclaimed his breakthrough invention of a workable electric light. That announcement was followed by many months of intense experimentation that led to the successful completion of his Pearl Street station four years later. Edison was not alone—nor was he first—in developing an incandescent light bulb, but his was the most successful of all competing inventions. Drawing from the documents in the Edison archives, Robert Friedel and Paul Israel explain how this came to be. They explore the process of invention through the Menlo Park notes, discussing the full range of experiments, including the testing of a host of materials, the development of such crucial tools as the world's best vacuum pump, and the construction of the first large-scale electrical generators and power distribution systems. The result is a fascinating story of excitement, risk, and competition. Revised and updated from the original 1986 edition, this definitive study of the most famous invention of America's most famous inventor is completely keyed to the printed and electronic versions of the Edison Papers, inviting the reader to explore further the remarkable original sources.

Book excerpt: Excerpt from The Manufacture of Carbons for Electric Lighting and Other Purposes Books and pamphlets abound upon most branches of electricity and allied subjects, but one notable exception is that of electric-light and electrolytic carbons, such as are extensively used in every civilised country of the world. It is true that "The Electrician" Printing and Publishing Company published, some years ago, a small pamphlet on the subject, but this simply related to the experiments that were made by a gentleman who was not engaged in practical business, but whose work will always find a place in the history of the development of the carbon industry. That so little has been written upon the subject of the manufacture of carbons, and that such a gap has existed for so long a time, is obviously due to the fact that very few have had a chance of thoroughly inspecting carbon works, which are usually as zealously guarded as a fortification. Carbon manufacturers have always been of the opinion that the less said upon the subject the better for them, and it is well known that the art of manufacturing high-grade carbons was always regarded as a sort of secret, of which a few only had the monopoly.
