Descripción del artículo del vendedor

London, Harrison and Sons, 1905. Bound in recent marbled boards. Both papers extracted from "Proceedings of the Royal Society of London", vol. 74, With title-page to volume 74. Pp. 476-487 and pp. 488-498. First printing of these two seminal articles, in which the basic principle of the modern wireless valve, also called the "Fleming Valve", is introduced for the first time, making radio-telephony and broadcasting possible. "The immense superiority of the Fleming thermionic valve to all previous detectors of wireless waves caused it to be widely used as an efficient and reliable detector." (PMM). When Lee DeForest perfected the "grid" in 1907, Fleming's wireless signals could be amplified to the degree necessary to make radio-telephony and broadcasting possible. The Edison effect was first described in a paper by William Henry Preece, who was shown an experiment by Edison "On a peculier of Glow-Lamps when raised to high Incasdence", 1885. This effect was known as the "Edison effect", and in 1890 Fleming, an electrical engineer who had worked with Edison Company in London and was now professor at University College, began a careful study of this phenomenon in carbon filament lamps. In 1904 he was able to demonstrate that this occurred not only with electric waves but also with wireless waves. He thus introduced the basic principle of the modern wireless valve, which permits only unilateral conductivity. (see PMM No. 396).Shiers, Early Television. A Bibliographical Guide to 1940, no. 323 (for the first article here present)" the article has been reprinted in George Shiers, ed. !The Telephone: An Historical Anthology", 1977. PMM no. 396 (for the first article here present). …
