James Joseph Drumm (1897 – 1974) was an Irish chemist and the inventor of the Drumm battery. Life Drumm was born in Dundrum, County Down, in 1897, and initially attended a national school where his mother taught. His secondary education was at St Macartan's College, Monaghan, where he won a county council scholarship. From 1914 to 1917 he studied at the ''Chemistry School'' of University College Dublin (UCD) and then worked in England at the ''Continuous Reaction Company''. In 1922 he returned to Dublin as a chemist for research and production at ''Fine Chemicals Ltd''. He then worked for various companies and participated in research projects. He modernized various processing methods, such as the conservation of peas, to keep their natural green colour in tin cans. According to Casey, from 1926 to 1931, Drumm worked tirelessly on a new accumulator and finally presented the Drumm Traction Battery.

Lead
Lead is a chemical element with the symbol Pb (from the Latin ) and atomic number 82. It is a heavy metal that is denser than most common materials. Lead is soft and malleable, and also has a relatively low melting point. When freshly cut, lead is a shiny gray with a hint of blue. It tarnishes to a dull gray color when exposed to air. Lead has the highest atomic number of any stable element and three of its isotopes are endpoints of major nuclear decay chains of heavier elements. Lead is toxic, even in small amounts, especially to children. Lead is a relatively unreactive post-transition metal. Its weak metallic character is illustrated by its amphoteric nature; lead and lead oxides react with acids and bases, and it tends to form covalent bonds. Compounds of lead are usually found in the +2 oxidation state rather than the +4 state common with lighter members of the carbon group. Exceptions are mostly limited to organolead compounds. Like the lighter members of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Railcar
A railcar (not to be confused with a railway car) is a self-propelled railway vehicle designed to transport passengers. The term "railcar" is usually used in reference to a train consisting of a single coach (carriage, car), with a driver's cab at one or both ends. Some railway companies, such as the Great Western, termed such vehicles "railmotors" (or "rail motors"). Self-propelled passenger vehicles also capable of hauling a train are, in technical rail usage, more usually called "rail motor coaches" or "motor cars" (not to be confused with the motor cars, otherwise known as automobiles, that operate on roads). The term is sometimes also used as an alternative name for the small types of multiple unit which consist of more than one coach. That is the general usage nowadays in Ireland when referring to any diesel multiple unit (DMU), or in some cases electric multiple unit (EMU). In North America the term "railcar" has a much broader sense and can be used (as an abbr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thomas Edison
Thomas Alva Edison (February 11, 1847October 18, 1931) was an American inventor and businessman. He developed many devices in fields such as electric power generation, mass communication, sound recording, and motion pictures. These inventions, which include the phonograph, the motion picture camera, and early versions of the electric light bulb, have had a widespread impact on the modern industrialized world. He was one of the first inventors to apply the principles of organized science and teamwork to the process of invention, working with many researchers and employees. He established the first industrial research laboratory. Edison was raised in the American Midwest. Early in his career he worked as a telegraph operator, which inspired some of his earliest inventions. In 1876, he established his first laboratory facility in Menlo Park, New Jersey, where many of his early inventions were developed. He later established a botanical laboratory in Fort Myers, Florida, in co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
