the metals

  • 1 Pliny the Elder (Gaius Plinius Secundus)

    SUBJECT AREA: Metallurgy
    [br]
    b. c. 23 AD Como, Italy
    d. 25 August 79 AD near Pompeii, Italy
    [br]
    Roman encyclopedic writer on the natural world.
    [br]
    Pliny was well educated in Rome, and for ten years or so followed a military career with which he was able to combine literary work, writing especially on historical subjects. He completed his duties c. 57 AD and concentrated on writing until he resumed his official career in 69 AD with administrative duties. During this last phase he began work on his only extant work, the thirty-seven "books" of his Historia Naturalis (Natural History), each dealing with a broad subject such as astronomy, geography, mineralogy, etc. His last post was the command of the fleet based at Misenum, which came to an end when he sailed too near Vesuvius during the eruption that engulfed Pompeii and he was overcome by the fumes.
    Pliny developed an insatiable curiosity about the natural world. Unlike the Greeks, the Romans made few original contributions to scientific thought and observation, but some made careful compilations of the learning and observations of Greek scholars. The most notable and influential of these was the Historia Naturalis. To the ideas about the natural world gleaned from earlier Greek authors, he added information about natural history, mineral resources, crafts and some technological processes, such as the extraction of metals from their ores, reported to him from the corners of the Empire. He added a few observations of his own, noted during travels on his official duties. Not all the reports were reliable, and the work often presents a tangled web of fact and fable. Gibbon described it as an immense register in which the author has "deposited the discoveries, the arts, and the errors of mankind". Pliny was indefatigable in his relentless note-taking, even dictating to his secretary while dining.
    During the Dark Ages and early Middle Ages in Western Europe, Pliny's Historia Naturalis was the largest known collection of facts about the natural world and was drawn upon freely by a succession of later writers. Its influence survived the influx into Western Europe, from the twelfth century, of translations of the works of Greek and Arab scholars. After the invention of printing in the middle of the fifteenth century, Pliny was the first work on a scientific subject to be printed, in 1469. Many editions followed and it may still be consulted with profit for its insights into technical knowledge and practice in the ancient world.

  • 6 Davy, Sir Humphry

    [br]
    b. 17 December 1778 Penzance, Cornwall, England
    d. 29 May 1829 Geneva, Switzerland
    [br]
    English chemist, discoverer of the alkali and alkaline earth metals and the halogens, inventor of the miner's safety lamp.
    [br]
    Educated at the Latin School at Penzance and from 1792 at Truro Grammar School, Davy was apprenticed to a surgeon in Penzance. In 1797 he began to teach himself chemistry by reading, among other works, Lavoisier's elementary treatise on chemistry. In 1798 Dr Thomas Beddoes of Bristol engaged him as assistant in setting up his Pneumatic Institution to pioneer the medical application of the newly discovered gases, especially oxygen.
    In 1799 he discovered the anaesthetic properties of nitrous oxide, discovered not long before by the chemist Joseph Priestley. He also noted its intoxicating qualities, on account of which it was dubbed "laughing-gas". Two years later Count Rumford, founder of the Royal Institution in 1800, appointed Davy Assistant Lecturer, and the following year Professor. His lecturing ability soon began to attract large audiences, making science both popular and fashionable.
    Davy was stimulated by Volta's invention of the voltaic pile, or electric battery, to construct one for himself in 1800. That enabled him to embark on the researches into electrochemistry by which is chiefly known. In 1807 he tried decomposing caustic soda and caustic potash, hitherto regarded as elements, by electrolysis and obtained the metals sodium and potassium. He went on to discover the metals barium, strontium, calcium and magnesium by the same means. Next, he turned his attention to chlorine, which was then regarded as an oxide in accordance with Lavoisier's theory that oxygen was the essential component of acids; Davy failed to decompose it, however, even with the aid of electricity and concluded that it was an element, thus disproving Lavoisier's view of the nature of acids. In 1812 Davy published his Elements of Chemical Philosophy, in which he presented his chemical ideas without, however, committing himself to the atomic theory, recently advanced by John Dalton.
    In 1813 Davy engaged Faraday as Assistant, perhaps his greatest service to science. In April 1815 Davy was asked to assist in the development of a miner's lamp which could be safely used in a firedamp (methane) laden atmosphere. The "Davy lamp", which emerged in January 1816, had its flame completely surrounded by a fine wire mesh; George Stephenson's lamp, based on a similar principle, had been introduced into the Northumberland pits several months earlier, and a bitter controversy as to priority of invention ensued, but it was Davy who was awarded the prize for inventing a successful safety lamp.
    In 1824 Davy was the first to suggest the possibility of conferring cathodic protection to the copper bottoms of naval vessels by the use of sacrificial electrodes. Zinc and iron were found to be equally effective in inhibiting corrosion, although the scheme was later abandoned when it was found that ships protected in this way were rapidly fouled by weeds and barnacles.

  • 14 BAUGR

    (-s, -ar), m.
    1) ring, armlet (of gold or silver) worn on the wrist, esp. the sacred ring (stallahringr) on the altar in heathen temples, cf. baugeiðr;
    2) in olden times, before minted gold or silver came into use, such rings were commonly used as a medium of payment; hence ‘baugr’ simply means money;
    3) fine of varying amount for manslaughter, weregild;
    4) gaff-hook?
    5) in the phrase, eiga (kost) á baugi, to have a (single) chance left; ef sá væri á. baugi, if there were no other chance; þú munt eiga slíkan á baugi brátt, thou wilt soon have the very same chance or lot (viz. death);
    * * *
    m. [the root bjúg—baug—bog; A. S. beág; O. H. G. pouc = armilla; lost in N. H. G. and in Engl.]
    I. a ring, armlet, esp. in olden times to be worn on the wrist plain, without stones:
    α. the sacred temple ring (stallahringr) on the altar in heathen temples; all oaths were’ to be made by laying the hand upon the temple ring; at sacrificial banquets it was to be dipped in the blood, and was to be worn by the priest at all meetings. The ring was either of gold or silver, open (mótlaus), its weight varying between two, three, and twenty ounces (the last is the reading of Eb. new Ed. p. 6, v. 1., the classical passages in the Sagas are—Eb. l. c. (and cp. 44), Glúm. 388, Landn. (Hb.) 258, Þórð. S. 94 (Ed. 1860); cp. also the note at the end of the new Ed. of Eb., referring to an interesting essay of the Norse Prof. Holmboe upon the matter, Christiania, A. D. 1864.
    β. baugr is at present in Icel. used of a spiral ring without a stone (e. g. a wedding ring); the third finger is called baugfingr, transl. from Lat. digitus annuli, for the wearing of wedding rings is not in use in Icel. (unless as a Dan. imitation). Icel. also say einbaugr, tvibaugr, a single or double spiral ring.
    II. metaph. in olden times, before minted gold or silver came into use, the metals were rolled up in spiral-formed rings, and pieces cut off and weighed were used as a medium of payment; hence, in old times, baugr simply means money, used in the poets in numberless compounds; hringum hreytti, hjó sundr baug, Rm. 35; cp. baugbroti, baugskyndir, baugskati, baughati, one who breaks, throws, hates gold, epithets of princes, etc., v. Lex. Poët. A. S. poetry abounds in epithets such as, beaggeafa, dator auri; the Heliand speaks of ‘vunden gold.’ In the law the payment of weregild is particularly called baugr, v. the compounds: baugatal is the Icel. section of law treating of the weregild, Grág. ii. 171–188; höfuôbaugr, lögbaugr ( a legal baug, lawful payment). In the Norse law vide esp. N. G. L. i. 74 sqq., 184 sqq.
    2. the painted circle on the round shield (clypeus); á fornum skjöldum var títt at skrifa rönd þá er b. var kallaðr, ok er við þann baug skildir kendir, Edda 87, Eg. 699; often embellished with scenes from the mythical age. Some poems arc preserved or on record, describing such shields, two Berudrápur by Egil (bera, a shield), Haustlöng by Thjodolf, Ragnarsdrápa by Bragi Gamli (of the 9th and 10th centuries). Some of these poems were among the chief sources used by Snorri in composing the Edda. The shield is metaph. called baugr, Edda (Gl.)
    3. a fish-hook; man eigi þú draga Leviathan á öngli eðr bora kiðr hans með baugi (very rare, if not an απ. λεγ.), Post. 686 C. 2.
    4. the phrase, eiga (kost) á baugi, to have (a single) chance left; þótti þat vera et mesta hætturáð at berjast, en sá mun á baugi, ef eigi er sæzt, there will be no other chance unless we come to terms, Sturl. iii. 244; þú munt eiga slíkan á baugi brátt, thou wilt soon have the very same chance (viz. death), the turn will come to thee, Nj. 58; nú mun ek eiga þann á baugi, at …, there will be no other chance for me, than …, Orkn. 46; cp. einbeygðr kostr, dira necessitas, 58; kvaðst þá heldr vilja liggja hjá henni, ef sá væri á baugi, if there were no other chance, Fas. ii. 150. The explanation of this metaphor is doubtful, cp. Vkv. verses 5 and 7 (?), or is the metaphor taken from the weregild?
    5. baugr also occurs in mod. usage in many compds, astron. and mathem., spor-baugr, the ecliptic; hádegisbaugr, a meridian.
    COMPDS: baugabrot, baugamaðr, baugatal, baugshelgi.

  • 16 Johnson, Percival Norton

    SUBJECT AREA: Metallurgy
    [br]
    b. 29 September 1792 London, England
    d. 1 June 1866 Stoke Fleming, Devon, England
    [br]
    English chemist, assayer, mining engineer and founder of the firm Johnson Matthey.
    [br]
    He was the son of John Johnson, then sole Commercial Assayer in London, from whom he inherited his aptitude for chemistry and metallurgy. At the age of 14 he was apprenticed to his father by the Worshipful Company of Goldsmiths. Ore samples then being analysed in Johnson's office introduced him to the new metal platinum, and resulted in a paper to Philosophical Magazine in 1812. Johnson established himself as a "practical mineralogist" in Maiden Lane, London, in 1818 and in Hatton Garden after 1822. He was greatly assisted by a fellow metallurgist, Thomas Cock (1787–1842), who developed the platinum fabrication and pigment sides of die business. In 1827 Johnson was consulted by the Russian government about the exploitation of the rich platinum deposits that had been discovered in the Urals in 1819. Between 1829 and 1832 Johnson became the first in England to manufacture nickel, extracted from nickel-bearing material imported from Germany at his plant at Bow Common on the Regent's Canal. In 1832 he began to réfine gold imported from the Imperial Brazilian Association by a process which separated without loss the metals silver, platinum, palladium, rhodium and iridium. This profitable activity continued until the Brazilian company was wound up in 1852. Since 1824, Johnson had been named "assay master" by a number of mining companies. From 1843 until the mid-1850s he had a considerable mining interest in the West Country. Meanwhile, the Hatton Garden establishment continued to prosper. In 1839 he was joined by George Matthey, who particularly fostered the Russian platinum business, and in 1851 he was taken unto partnership and the firm became the celebrated Johnson Matthey. In the following year the firm was officially recognized as one of the four Assayers to the Bank of England appointed to handle the flood of gold dust then arriving in England from the Australian gold fields. Soon after, however, ill health compelled him to retire to his Devon country house.

    Effects of the electric arc inside switchgear and controlgear assemblies

    In the proximity of the main boards, i.e. in the proximity of big electrical machines, such as transformers or generators, the short-circuit power is high and consequently also the energy associated with the electrical arc due to a fault is high.

    Without going into complex mathematical descriptions of this phenomenon, the first instants of arc formation inside a cubicle can be schematized in 4 phases:

    1. compression phase: in this phase the volume of the air where the arc develops is overheated owing to the continuous release of energy; due to convection and radiation the remaining volume of air inside the cubicle warms up; initially there are temperature and pressure values different from one zone to another;

    2. expansion phase: from the first instants of internal pressure increase a hole is formed through which the overheated air begins to go out. In this phase the pressure reaches its maximum value and starts to decrease owing to the release of hot air;

    3. emission phase: in this phase, due to the continuous contribution of energy by the arc, nearly all the air is forced out under a soft and almost constant overpressure;

    4. thermal phase: after the expulsion of the air, the temperature inside the switchgear reaches almost that of the electrical arc, thus beginning this final phase which lasts till the arc is quenched, when all the metals and the insulating materials coming into contact undergo erosion with production of gases, fumes and molten material particles.

    Should the electrical arc occur in open configurations, some of the described phases could not be present or could have less effect; however, there shall be a pressure wave and a rise in the temperature of the zones surrounding the arc.

    Being in the proximity of an electrical arc is quite dangerous; here are some data to understand how dangerous it is:

    • pressure: at a distance of 60 cm from an electrical arc associated with a 20 kA arcing fault a person can be subject to a force of 225 kg; moreover, the sudden pressure wave may cause permanent injuries to the eardrum;
    • arc temperatures: about 7000-8000 °C;
    • sound: electrical arc sound levels can reach 160 db, a shotgun blast only 130 db.

    Действие электрической дуги, возникающей внутри НКУ распределения и управления

    Короткое замыкание вблизи больших силовых устройств, таких как трансформаторы или генераторы имеет очень большую мощность. Поэтому энергия электрической дуги, возникшей в результате короткого замыкания, очень большая.

    Не вдаваясь в сложное математическое описание данного явления, можно сказать, что первые мгновения формирования дуги внутри шкафа можно упрощенно разделить на четыре этапа:

    1. Этап сжатия: на этом этапе объем воздуха, в котором происходит зарождение дуги перегревается вследствие непрерывного высвобождения энергии. За счет конвекции и излучения оставшийся объем воздуха внутри шкафа нагревается. На этом начальном этапе значения температуры и давления воздуха в разных зонах НКУ разные.

    2. Этап расширения: с первых мгновений внутреннее давление создает канал, через который начинается движение перегретого воздуха. На этом этапе давление достигает своего максимального значения, после чего начинает уменьшаться вследствие выхода горячего воздуха.

    3. Этап эмиссии: на этом этапе вследствие непрерывного пополнения энергией дуги почти весь воздух выталкивается под действием мягкого и почти постоянного избыточного давления.

    4. Термический этап: после выхлопа воздуха температура внутри НКУ почти достигает температуры электрической дуги. Так начинается заключительный этап, который длится до тех пор, пока дуга не погаснет. При этом все металлические и изоляционные материалы, вступившие в контакт с дугой, оказываются подвергнутыми эрозии с выделением газов, дыма и частиц расплавленного материала.

    Если электрическая дуга возникнет в открытом НКУ, то некоторые из описанных этапов могут не присутствовать или могут иметь меньшее воздействие. Тем не менее будет иметь место воздушная волна и подъем температуры вблизи дуги.

    Находиться вблизи электрической дуги довольно опасно. Ниже приведены некоторые сведения, помогающие осознать эту опасность:

    • давление: На расстоянии 60 см от электрической дуги, вызванной током короткого замыкания 20 кА, человек может подвергнуться воздействию силы 225 кг. Более того, резкая волна давления может нанести тяжелую травму барабанным перепонкам;
    • температура дуги: около 7000-8000 °C;
    • шумовое воздействие: Уровень шумового воздействия электрической дуги может достигнуть 160 дБ (выстрел из дробовика – 130 дБ).
