  • 2 Smith, Sir Francis Pettit

    SUBJECT AREA: Ports and shipping
    [br]
    b. 9 February 1808 Copperhurst Farm, near Hythe, Kent, England
    d. 12 February 1874 South Kensington, London, England
    [br]
    English inventor of the screw propeller.
    [br]
    Smith was the only son of Charles Smith, Postmaster at Hythe, and his wife Sarah (née Pettit). After education at a private school in Ashford, Kent, he took to farming, first on Romney Marsh, then at Hendon, Middlesex. As a boy, he showed much skill in the construction of model boats, especially in devising their means of propulsion. He maintained this interest into adult life and in 1835 he made a model propelled by a screw driven by a spring. This worked so well that he became convinced that the screw propeller offered a better method of propulsion than the paddle wheels that were then in general use. This notion so fired his enthusiasm that he virtually gave up farming to devote himself to perfecting his invention. The following year he produced a better model, which he successfully demonstrated to friends on his farm at Hendon and afterwards to the public at the Adelaide Gallery in London. On 31 May 1836 Smith was granted a patent for the propulsion of vessels by means of a screw.
    The idea of screw propulsion was not new, however, for it had been mooted as early as the seventeenth century and since then several proposals had been advanced, but without successful practical application. Indeed, simultaneously but quite independently of Smith, the Swedish engineer John Ericsson had invented the ship's propeller and obtained a patent on 13 July 1836, just weeks after Smith. But Smith was completely unaware of this and pursued his own device in the belief that he was the sole inventor.
    With some financial and technical backing, Smith was able to construct a 10 ton boat driven by a screw and powered by a steam engine of about 6 hp (4.5 kW). After showing it off to the public, Smith tried it out at sea, from Ramsgate round to Dover and Hythe, returning in stormy weather. The screw performed well in both calm and rough water. The engineering world seemed opposed to the new method of propulsion, but the Admiralty gave cautious encouragement in 1839 by ordering that the 237 ton Archimedes be equipped with a screw. It showed itself superior to the Vulcan, one of the fastest paddle-driven ships in the Navy. The ship was put through its paces in several ports, including Bristol, where Isambard Kingdom Brunel was constructing his Great Britain, the first large iron ocean-going vessel. Brunel was so impressed that he adapted his ship for screw propulsion.
    Meanwhile, in spite of favourable reports, the Admiralty were dragging their feet and ordered further trials, fitting Smith's four-bladed propeller to the Rattler, then under construction and completed in 1844. The trials were a complete success and propelled their lordships of the Admiralty to a decision to equip twenty ships with screw propulsion, under Smith's supervision.
    At last the superiority of screw propulsion was generally accepted and virtually universally adopted. Yet Smith gained little financial reward for his invention and in 1850 he retired to Guernsey to resume his farming life. In 1860 financial pressures compelled him to accept the position of Curator of Patent Models at the Patent Museum in South Kensington, London, a post he held until his death. Belated recognition by the Government, then headed by Lord Palmerston, came in 1855 with the grant of an annual pension of £200. Two years later Smith received unofficial recognition when he was presented with a national testimonial, consisting of a service of plate and nearly £3,000 in cash subscribed largely by the shipbuilding and engineering community. Finally, in 1871 Smith was honoured with a knighthood.

  • 4 Smith, Oberlin

    [br]
    b. 22 March 1840 Cincinnati, Ohio, USA
    d. 18 July 1926
    [br]
    American mechanical engineer, pioneer in experiments with magnetic recording.
    [br]
    Of English descent, Smith embarked on an education in mechanical engineering, graduating from West Jersey Academy, Bridgeton, New Jersey, in 1859. In 1863 he established a machine shop in Bridgeton, New Jersey, that became the Ferracute Machine Company in 1877, eventually specializing in the manufacture of presses for metalworking. He seems to have subscribed to design principles considered modern even in the 1990s, "always giving attention to the development of artistic form in combination with simplicity, and with massive strength where required" (bibliographic reference below). He was successful in his business, and developed and patented a large number of mechanical constructions.
    Inspired by the advent of the phonograph of Edison, in 1878 Smith obtained the tin-foil mechanical phonograph, analysed its shortcomings and performed some experiments in magnetic recording. He filed a caveat in the US Patent Office in order to be protected while he "reduced the invention to practice". However, he did not follow this trail. When there was renewed interest in practical sound recording and reproduction in 1888 (the constructions of Berliner and Bell \& Tainter), Smith published an account of his experiments in the journal Electrical World. In a corrective letter three weeks later it is clear that he was aware of the physical requirements for the interaction between magnetic coil and magnetic medium, but his publications also indicate that he did not as such obtain reproduction of recorded sound.
    Smith did not try to develop magnetic recording, but he felt it imperative that he be given credit for conceiving the idea of it. When accounts of Valdemar Poulsen's work were published in 1900, Smith attempted to prove some rights in the invention in the US Patent Office, but to no avail.
    He was a highly respected member of both his community and engineering societies, and in later life became interested in the anti-slavery cause that had also been close to the heart of his parents, as well as in the YMCA movement and in women's suffrage.
    [br]
    Bibliography
    Apart from numerous technical papers, he wrote the book Press Working of Metals, 1896. His accounts on the magnetic recording experiments were "Some possible forms of phonograph", Electrical World (8 September 1888): 161 ff, and "Letter to the Editor", Electrical World (29 September 1888): 179.

  • 5 Zonca, Vittorio

    [br]
    b. c. 1568 Italy
    d. 1603 Italy
    [br]
    Italian architect who wrote a book on machines.
    [br]
    All that is known of Zonca is included on the frontispiece of the book that is his only claim to fame. He is there described as architect to the "Magnificent Community of Padua". He compiled a book on machines entitled Novo teatro de machine ed edificii (New Display of Machines and Edifices), illustrated with numerous fine engravings. It was printed in Padua in 1607, four years after his death, by Francesco Bertelli, who said of the book that it "came into my hands", as though he knew nothing of the author.
    During the sixteenth and early seventeenth centuries, a number of illustrated books on technical subjects appeared, compiled by knowledgeable and educated authors. These books greatly helped the spread of information about the technical arts throughout Europe. There were several books on mechanical devices, notably those by Ramelli, Besson and Zonca. In some ways, Zonca's is the most interesting, for it seems closest to the mechanical practice of the time. Several of the machines he describes are referred to as being in use in Padua or Venice and he suggests ways of improving them. The range of machines is wider than in other similar works and includes pumps, cranes, powder mills, printing and bookbinding presses and textile machines. Perhaps the most interesting of these is the water-driven silk-threading machine, since some of its components resemble those in use in the twentieth century. Spinning mills were widely used in the silk industry in sixteenth-century Italy, and Zonca offers a full description of one. He also shows the first example of an oblique treadwheel, driven by oxen for the grinding of grain. Even so, despite all the practical detail, the book ends, like others of its kind, with fantasy, in a description of a perpetual-motion machine.

    arc-resistant switchgear
    A type of switchgear design which is designed to withstand the effects of an internal arcing fault, without causing harm to personnel who are located in defined areas. It is not intended to withstand these internal arcing fault without possibly causing physical damage to the structure and/or components, but often the physical damage is less with an arc-resistant design.

    There are three classes of protection:
    Type A - eliminates the emission of gases and particles from the front of the switchgear during an internal arcing fault,
    Type B - eliminates the emission of gases and particles from the front and sides of the switchgear during an internal arcing fault,
    Type C - eliminates the emission of gases and particles from the front and sides of the switchgear, from between compartments within the same cell, and between adjacent cells during an internal arcing fault.

    Arc-resistant switchgear has traditionally been metal-clad, but the basic concept could also be applied to other types of switchgear as well.

    arc-proof switchgear
    An incorrect term. Please refer to arc-resistant switchgear

    If the electric arc occurs inside LV switchgear it generates internal overpressures and results in local overheatings which may cause high mechanical and thermal stresses in the equipment.

    Besides, the involved materials can generate hot decomposition products, gases or fumes, which, due to the overpressure, are almost always ejected to the outside of the enclosure thus jeopardizing the operator safety.

    The European Directive 2006/95/EC states the fundamental safety requirements for low voltage electric materials (from 50 V to 1000 V in alternating current, from 75 V to 1500 V in continuos current) to be put on the market within the European Community.

    Among the essential safety requirements defined by this Directive particular importance is given to the need of taking technical measures to prevent “temperature rises, electric arcs or radiations which may result in hazards” from occurring.

    This aspect has always been highly considered for apparatus, but it has been wrongly neglected for electrical switchgear and only in the last 10-15 years it has been catching on both at Italian as well as at international level.

    Safety for the operator and for the installation in case of arcing inside LV switchgear can be obtained through three different design philosophies:
    1. assemblies mechanically capable of withstanding the electric arc (passive protection)
    2. assemblies equipped with devices limiting the effects of internal arcing (active protection)
    3. assemblies equipped with current limiting circuitbreakers.

    These three solutions (also combined together) have found a remakable development in the industrial field and have been successfully applied by the main manufacturers of LV switchgear and controlgear assemblies.

    As it can be seen hereafter by examining the first two solutions, an “active” protection against arc faults is intrinsecally more complex than a “passive” one.

    This because of the presence of additional electromechanical/ electronic devices5 which limit the arcing effects and which, by their nature, may be subject to faults or not-tripping.

    Дуга, возникшая внутри НКУ, создает внутреннее избыточное давление и вызывает локальный перегрев, что может привести к воздействию на оборудование значительного механического напряжения и перепада температур.

    Кроме того, под воздействием дуги различные материалы разлагаются на продукты, имеющие высокую температуру, в том числе газы и дым, которые почти всегда вырываются из оболочки НКУ под высоким давлением, подвергая опасности оперативный персонал.

    Европейская директива 2006/95/EC определяет основные требования безопасности для низковольтного (от 50 до 1000 В переменного тока и от 75 до 1500 В постоянного тока) оборудования поставляемого на рынок Европейского Сообщества.

    Одно из основных требований безопасности, определяемое данной директивой как наиболее важное, заключается в необходимости предпринять технические меры для предотвращения "подъема температуры, возникновения электрической дуги или излучения", которые могут причинить ущерб.

    Данная проблема всегда учитывалась при создании различных аппаратов, но незаслуженно игнорировалась при разработке электрических комплектных устройств, и только в последние 10-15 лет ей стали уделять должное внимание как в Италии, так и во всем мире.

    При возникновении электрической дуги внутри НКУ безопасность оператора и электроустановки обеспечивается тремя способами:
    1. Конструкция НКУ должна выдерживать механические воздействия, возникающие при горении электрической дуги (пассивная защита).
    2. НКУ должно быть оснащено устройствами, ограничивающими воздействие электрической дуги (активная защита)
    3. НКУ должны быть оснащены токоограничивающими автоматическими выключателями.

    Указанные три способа (применяемые совместно) получили дальнейшее развитие в промышленности и успешно применяются основными изготовителями НКУ распределения и управления.

    Как будет показано далее при рассмотрении первых двух способов, активная защита от дуговых» неисправностей является более сложной, чем пассивная защита.

    Это объясняется необходимостью использования дополнительных электромеханических или электронных устройств, задачей которых является ограничение воздействий дуги и которые сами могут оказаться неисправными и не сработать.
