   Portugal's independence and sovereignty as a nation-state are based on being separate from Spain. Achieving this on a peninsula where its only landward neighbor, Spain, is stronger, richer, larger, and more populous, raises interesting historical questions. Considering the disparity in size of population alone — Spain (as of 2000) had a population of 40 million, whereas Portugal's population numbered little over 10 million—how did Portugal maintain its sometimes precarious independence? If the Basques, Catalans, and Galicians succumbed to Castilian military and political dominance and were incorporated into greater Spain, how did little Portugal manage to survive the "Spanish menace?" A combination of factors enabled Portugal to keep free of Spain, despite the era of "Babylonian Captivity" (1580-1640). These include an intense Portuguese national spirit; foreign assistance in staving off Spanish invasions and attacks between the late 14th century and the mid l9th century, principally through the Anglo- Portuguese Alliance and some assistance from France; historical circumstances regarding Spain's own trials and tribulations and decline in power after 1600.

   In Portugal's long history, Castile and Leon (later "Spain," as unified in the 16th century) acted as a kind of Iberian mother and stepmother, present at Portugal's birth as well as at times when Portuguese independence was either in danger or lost. Portugal's birth as a separate state in the 12th century was in part a consequence of the king of Castile's granting the "County of Portucale" to a transplanted Burgundian count in the late 11th century. For centuries Castile, Leon, Aragon, and Portugal struggled for supremacy on the peninsula, until the Castilian army met defeat in 1385 at the battle of Aljubarrota, thus assuring Portugal's independence for nearly two centuries. Portugal and its overseas empire suffered considerably under rule by Phillipine Spain (1580-1640). Triumphant in the War of Restoration against Spain (1640-68), Portugal came to depend on its foreign alliances to provide a counterweight to a still menacing kindred neighbor. Under the Anglo-Portuguese Alliance, England (later Great Britain) managed to help Portugal thwart more than a few Spanish invasion threats in the next centuries. Rumors and plots of Spain consuming Portugal continued during the 19th century and even during the first Portuguese republic's early years to 1914.

   Following difficult diplomatic relations during Spain's subsequent Second Republic (1931-36) and civil war (1936-39), Luso-Span-ish relations improved significantly under the authoritarian regimes that ruled both states until the mid-1970s. Portugal's prime minister Antônio de Oliveira Salazar and Spain's generalissimo Francisco Franco signed nonaggression and other treaties, lent each other mutual support, and periodically consulted one another on vital questions. During this era (1939-74), there were relatively little trade, business, and cultural relations between the two neighbors, who mainly tended to ignore one another. Spain's economy developed more rapidly than Portugal's after 1950, and General Franco was quick to support the Estado Novo across the frontier if he perceived a threat to his fellow dictator's regime. In January 1962, for instance, Spanish army units approached the Portuguese frontier in case the abortive military coup at Beja (where a Portuguese oppositionist plot failed) threatened the Portuguese dictatorship.

   Since Portugal's Revolution of 25 April 1974, and the death of General Franco and the establishment of democracy in Spain (1975-78), Luso-Spanish relations have improved significantly. Portugal has experienced a great deal of Spanish investment, tourism, and other economic activities, since both Spain and Portugal became members of the European Economic Community (EEC) in 1986.

   Yet, Portugal's relations with Spain have become closer still, with increased integration in the European Union. Portugal remains determined not to be confused with Spain, and whatever threat from across the frontier exists comes more from Spanish investment than from Spanish winds, marriages, and armies. The fact remains that Luso-Spanish relations are more open and mutually beneficial than perhaps at any other time in history.

John Arnold was apprenticed to his father, a watchmaker, and then worked as an itinerant journeyman in the Low Countries and, later, in England. He settled in London in 1762 and rapidly established his reputation at Court by presenting George III with a miniature repeating watch mounted in a ring. He later abandoned the security of the Court for a more precarious living developing his chronometers, with some financial assistance from the Board of Longitude. Symbolically, in 1771 he moved from the vicinity of the Court at St James's to John Adam Street, which was close to the premises of the Royal Society for the Encouragement of Arts, Manufactures \& Commerce.

By the time Arnold became interested in chronometry, Harrison had already demonstrated that longitude could be determined by means of a timekeeper, and the need was for a simpler instrument that could be sold at an affordable price for universal use at sea. Le Roy had shown that it was possible to dispense with a remontoire by using a detached escapement with an isochronous balance; Arnold was obviously thinking along the same lines, although he may not have been aware of Le Roy's work. By 1772 Arnold had developed his detached escapement, a pivoted detent which was quite different from that used on the European continent, and three years later he took out a patent for a compensation balance and a helical balance spring (Arnold used the spring in torsion and not in tension as Harrison had done). His compensation balance was similar in principle to that described by Le Roy and used riveted bimetallic strips to alter the radius of gyration of the balance by moving small weights radially. Although the helical balance spring was not completely isochronous it was a great improvement on the spiral spring, and in a later patent (1782) he showed how it could be made more truly isochronous by shaping the ends. In this form it was used universally in marine chronometers.

Although Arnold's chronometers performed well, their long-term stability was less satisfactory because of the deterioration of the oil on the pivot of the detent. In his patent of 1782 he eliminated this defect by replacing the pivot with a spring, producing the spring detent escapement. This was also done independendy at about the same time by Berthoud and Earnshaw, although Earnshaw claimed vehemently that Arnold had plagiarized his work. Ironically it was Earnshaw's design that was finally adopted, although he had merely replaced Arnold's pivoted detent with a spring, while Arnold had completely redesigned the escapement. Earnshaw also improved the compensation balance by fusing the steel to the brass to form the bimetallic element, and it was in this form that it began to be used universally for chronometers and high-grade watches.

As a result of the efforts of Arnold and Earnshaw, the marine chronometer emerged in what was essentially its final form by the end of the eighteenth century. The standardization of the design in England enabled it to be produced economically; whereas Larcum Kendall was paid £500 to copy Harrison's fourth timekeeper, Arnold was able to sell his chronometers for less than one-fifth of that amount. This combination of price and quality led to Britain's domination of the chronometer market during the nineteenth century.

After education in Hungary and a period as an assistant at the Technische Hochschule, Berlin, Goldmark moved to England, where he joined Pye of Cambridge and worked on an experimental thirty-line television system using a cathode ray tube (CRT) for the display. In 1936 he moved to the USA to work at Columbia Broadcasting Laboratories. There, with monochrome television based on the CRT virtually a practical proposition, he devoted his efforts to finding a way of producing colour TV images: in 1940 he gave his first demonstration of a working system. There then followed a series of experimental field-sequential colour TV systems based on segmented red, green and blue colour wheels and drums, where the problem was to find an acceptable compromise between bandwidth, resolution, colour flicker and colour-image breakup. Eventually he arrived at a system using a colour wheel in combination with a CRT containing a panchromatic phosphor screen, with a scanned raster of 405 lines and a primary colour rate of 144 fields per second. Despite the fact that the receivers were bulky, gave relatively poor, dim pictures and used standards totally incompatible with the existing 525-line, sixty fields per second interlaced monochrome (black and white) system, in 1950 the Federal Communications Commission (FCC), anxious to encourage postwar revival of the industry, authorized the system for public broadcasting. Within eighteen months, however, bowing to pressure from the remainder of the industry, which had formed its own National Television Systems Committee (NTSC) to develop a much more satisfactory, fully compatible system based on the RCA three-gun shadowmask CRT, the FCC withdrew its approval.

While all this was going on, Goldmark had also been working on ideas for overcoming the poor reproduction, noise quality, short playing-time (about four minutes) and limited robustness and life of the long-established 78 rpm 12 in. (30 cm) diameter shellac gramophone record. The recent availability of a new, more robust, plastic material, vinyl, which had a lower surface noise, enabled him in 1948 to reduce the groove width some three times to 0.003 in. (0.0762 mm), use a more lightly loaded synthetic sapphire stylus and crystal transducer with improved performance, and reduce the turntable speed to 33 1/3 rpm, to give thirty minutes of high-quality music per side. This successful development soon led to the availability of stereophonic recordings, based on the ideas of Alan Blumlein at EMI in the 1930s.

In 1950 Goldmark became a vice-president of CBS, but he still found time to develop a scan conversion system for relaying television pictures to Earth from the Lunar Orbiter spacecraft. He also almost brought to the market a domestic electronic video recorder (EVR) system based on the thermal distortion of plastic film by separate luminance and coded colour signals, but this was overtaken by the video cassette recorder (VCR) system, which uses magnetic tape.

Holland was educated first in his native town and later in Limerick, a seaport bustling with coastal trade ships. His first job was that of schoolteacher, and as such he worked in various parts of Ireland until he was about 32 years old. A combination of his burning patriotic zeal for Ireland and his interest in undersea technology (then in its infancy) made him consider designs for underwater warships for use against the British Royal Navy in the fight for Irish independence. He studied all known works on the subject and commenced drawing plans, but he was unable to make real headway owing to a lack of finance.

In 1873 he travelled to the United States, ultimately settling in New Jersey and continuing in the profession of teaching. His work on submarine design continued, but in 1875 he suffered a grave setback when the United States Navy turned down his designs. Help came from an unexpected source, the Irish Republican Brotherhood, or Fenian Society, which had been founded in Dublin and New York in 1858. Financial help enabled Holland to build a 4 m (13 ft) one-person craft, which was tested in 1878, and then a larger boat of 19 tonnes' displacement that was tested with a crew of three to depths of 20 m (65 ft) in New York's harbour in 1883. Known as the Fenian Ram, it embodied most of the principles of modern submarines, including weight compensation. The Fenians commandeered this boat, but they were unable to operate it satisfactorily and it was relegated to history.

Holland continued work, at times independently and sometimes with others, and continuously advocated submarines to the United States Navy. In 1895 he was successful in winning a contract for US$150,000 to build the US Submarine Plunger at Baltimore. With too much outside interference, this proved an unsatisfactory venture. However, with only US$5,000 of his capital left, Holland started again and in 1898 he launched the Holland at Elizabeth, New Jersey. This 16 m (52 ft) vessel was successful, and in 1900 it was purchased by the United States Government.

Six more boats were ordered by the Americans, and then some by the Russians and the Japanese. The British Royal Navy ordered five, which were built by Vickers Son and Maxim (now VSEL) at Barrow-in-Furness in the years up to 1903, commencing their long run of submarine building. They were licensed by another well-known name, the Electric Boat Company, which had formerly been the J.P.Holland Torpedo Boat Company.

Holland now had some wealth and was well known. He continued to work, trying his hand at aeronautical research, and in 1904 he invented a respirator for use in submarine rescue work. It is pleasing to record that one of his ships can be seen to this day at the Royal Navy Submarine Museum, Gosport: HM Submarine Holland No. 1, which was lost under tow in 1913 but salvaged and restored in the 1980s.

Jacquard was apprenticed at the age of 12 to bookbinding, and later to type-founding and cutlery. His parents, who had some connection with weaving, left him a small property upon their death. He made some experiments with pattern weaving, but lost all his inheritance; after marrying, he returned to type-founding and cutlery. In 1790 he formed the idea for his machine, but it was forgotten amidst the excitement of the French Revolution, in which he fought for the Revolutionists at the defence of Lyons. The machine he completed in 1801 combined earlier inventions and was for weaving net. He was sent to Paris to demonstrate it at the National Exposition and received a bronze medal. In 1804 Napoleon granted him a patent, a pension of 1,500 francs and a premium on each machine sold. This enabled him to study and work at the Conservatoire des Arts et Métiers to perfect his mechanism for pattern weaving. A method of selecting any combination of leashes at each shoot of the weft had to be developed, and Jacquard's mechanism was the outcome of various previous inventions. By taking the cards invented by Falcon in 1728 that were punched with holes like the paper of Bouchon in 1725, to select the needles for each pick, and by placing the apparatus above the loom where Vaucanson had put his mechanism, Jacquard combined the best features of earlier inventions. He was not entirely successful because his invention failed in the way it pressed the card against the needles; later modifications by Breton in 1815 and Skola in 1819 were needed before it functioned reliably. However, the advantage of Jacquard's machine was that each pick could be selected much more quickly than on the earlier draw looms, which meant that John Kay's flying shuttle could be introduced on fine pattern looms because the weaver no longer had to wait for the drawboy to sort out the leashes for the next pick. Robert Kay's drop box could also be used with different coloured wefts. The drawboy could be dispensed with because the foot-pedal operating the Jacquard mechanism could be worked by the weaver. Patterns could be changed quickly by replacing one set of cards with another, but the scope of the pattern was more limited than with the draw loom. Some machines that were brought into use aroused bitter hostility. Jacquard suffered physical violence, barely escaping with his life, and his machines were burnt by weavers at Lyons. However, by 1812 his mechanism began to be generally accepted and had been applied to 11,000 draw-looms in France. In 1819 Jacquard received a gold medal and a Cross of Honour for his invention. His machines reached England c.1816 and still remain the basic way of weaving complicated patterns.

Automation technologies: a strong focal point for our R&D

Технологии для автоматизации - одна из главных тем наших научно исследовательских разработок

Automation is an area of ABB’s business with an extremely high level of technological innovation.

Автоматика относится к одной из областей деятельности компании АББ, для которой характерен исключительно высокий уровень технических инноваций.

In fact, it may be seen as a showcase for exhibiting the frontiers of development in several of today’s emerging technologies, like short-range wireless communication and microelectromechanical systems (MEMS).

В определенном смысле ее можно уподобить витрине, в которой выставлены передовые разработки из области только еще зарождающихся технологий, примерами которых являются ближняя беспроводная связь и микроэлектромеханические системы (micro electromechanical systems MEMS).

Mechatronics – the synthesis of mechanics and electronics – is another very exciting and rapidly developing area, and the foundation on which ABB has built its highly successful, fast-growing robotics business.

Еще одной исключительно интересной быстро развивающейся областью и в то же время фундаментом, на котором АББ в последнее время строит свой исключительно успешный и быстро расширяющийся бизнес в области робототехники, является мехатроника - синтез механики с электроникой.

Robotic precision has now reached the levels we have come to expect of the watch-making industry, while robots’ mechanical capabilities continue to improve significantly.

Точность работы робототехнических устройств достигла сегодня уровней, которые мы привыкли ожидать только на предприятиях часовой промышленности. Большими темпами продолжают расти и механические возможности роботов.

Behind the scenes, highly sophisticated electronics and software control every move these robots make.

А за кулисами всеми перемещениями робота управляют сложные электронные устройства и компьютерные программы.

Throughout industry today we see a major shift of ‘intelligence’ to lower levels in the automation system hierarchy, leading to a demand for more communication within the system.

Во всех отраслях промышленности сегодня наблюдается интенсивный перенос "интеллекта" на нижние уровни иерархии автоматизированных систем, что требует дальнейшего развития внутрисистемных средств обмена.

‘Smart’ transmitters, with powerful microprocessors, memory chips and special software, carry out vital operations close to the processes they are monitoring.

"Интеллектуальные" датчики, снабженные высокопроизводительными микропроцессорами, мощными чипами памяти и специальным программно-математическим обеспечением, выполняют особо ответственные операции в непосредственной близости от контролируемых процессов.

And they capture and store data crucial for remote diagnostics and maintenance.

Они же обеспечивают возможность измерения и регистрации информации, крайне необходимой для дистанционной диагностики и дистанционного обслуживания техники.

The communication highway linking such systems is provided by fieldbuses.

В качестве коммуникационных магистралей, связывающих такого рода системы, служат промышленные шины fieldbus.

In an ideal world there would be no more than a few, preferably just one, fieldbus standard.

В идеале на промышленные шины должно было бы существовать небольшое количество, а лучше всего вообще только один стандарт.

However, there are still too many of them, so ABB has developed ‘fieldbus plugs’ that, with the help of translation, enable devices to communicate across different standards.

К сожалению, на деле количество их типов продолжает оставаться слишком разнообразным. Ввиду этой особенности рынка промышленных шин компанией АББ разработаны "штепсельные разъемы", которые с помощью средств преобразования обеспечивают общение различных устройств вопреки границам, возникшим из-за различий в стандартах.

This makes life easier as well as less costly for our customers. Every automation system is dependent on an electrical network for distributing – and interrupting, when necessary – the power needed to carry out its various functions.

Это, безусловно, не только облегчает, но и удешевляет жизнь нашим заказчикам. Ни одна система автоматики не может работать без сети, обеспечивающей подачу, а при необходимости и отключение напряжения, необходимого для выполнения автоматикой своих задач.

Here, too, we see a clear trend toward more intelligence and communication, for example in traditional electromechanical devices such as contactors and switches.

И здесь наблюдаются отчетливо выраженные тенденции к повышению уровня интеллектуальности и расширению возможностей связи, например, в таких традиционных электромеханических устройствах, как контакторы и выключатели.

We are pleased to see that our R&D efforts in these areas over the past few years are bearing fruit.

Мы с удовлетворением отмечаем, что научно-исследовательские разработки, выполненные нами за последние годы в названных областях, начинают приносить свои плоды.

Recently, we have seen a strong increase in the use of wireless technology in industry.

В последнее время на промышленных предприятиях наблюдается резкое расширение применения техники беспроводной связи.

This is a key R&D area at ABB, and several prototype applications have already been developed.

В компании АББ эта область также относится к числу одной из ключевых тем научно-исследовательских разработок, результатом которых стало создание ряда опытных образцов изделий практического направления.

At the international Bluetooth Conference in Amsterdam in June 2002, we presented a truly ‘wire-less’ proximity sensor – with even a wireless power supply.

На международной конференции по системам Bluetooth, состоявшейся в Амстердаме в июне 2002 г., наши специалисты выступили с докладом о поистине "беспроводном" датчике ближней локации, снабженном опять-таки "беспроводным" источником питания.

This was its second major showing after the launch at the Hanover Fair.

На столь крупном мероприятии это устройство демонстрировалось во второй раз после своего первого показа на Ганноверской торгово-промышленной ярмарке.

Advances in microelectronic device technology are also having a profound impact on the power electronics systems around which modern drive systems are built.

Достижения в области микроэлектроники оказывают также глубокое влияние на системы силовой электроники, лежащие в основе современных приводных устройств.

The ABB drive family ACS 800 is visible proof of this.

Наглядным тому доказательством может служить линейка блоков регулирования частоты вращения электродвигателей ACS-800, производство которой начато компанией АББ.

Combining advanced trench gate IGBT technology with efficient cooling and innovative design, this drive – for motors rated from 1.1 to 500 kW – has a footprint for some power ranges which is six times smaller than competing systems.

Предназначены они для двигателей мощностью от 1,1 до 500 кВт. В блоках применена новейшая разновидность приборов - биполярные транзисторы с изолированным желобковым затвором (trench gate IGBT) в сочетании с новыми конструктивными решениями, благодаря чему в отдельных диапазонах мощностей габариты блоков удалось снизить по сравнению с конкурирующими изделиями в шесть раз.

To get the maximum benefit out of this innovative drive solution we have also developed a new permanent magnet motor.

Стремясь с максимальной пользой использовать новые блоки регулирования, мы параллельно с ними разработали новый двигатель с постоянными магнитами.

It uses neodymium iron boron, a magnetic material which is more powerful at room temperature than any other known today.

В нем применен новый магнитный материал на основе неодима, железа и бора, характеристики которого при комнатной температуре на сегодняшний день не имеют себе равных.

The combination of new drive and new motor reduces losses by as much as 30%, lowering energy costs and improving sustainability – both urgently necessary – at the same time.

Совместное использование нового блока регулирования частоты вращения с новым двигателем снижает потери мощности до 30 %, что позволяет решить сразу две исключительно актуальные задачи:
сократить затраты на электроэнергию и повысить уровень безотказности.

These innovations are utilized most fully, and yield the maximum benefit, when integrated by means of our Industrial IT architecture.

Потенциал перечисленных выше новых разработок используется в наиболее полной степени, а сами они приносят максимальную выгоду, если их интеграция осуществлена на основе нашей архитектуры IndustrialIT.

Industrial IT is a unique platform for exploiting the full potential of information technology in industrial applications.

IndustrialIT представляет собой уникальную платформу, позволяющую в максимальной степени использовать возможности информационных технологий применительно к задачам промышленности.

Consequently, our new products and technologies are Industrial IT Enabled, meaning that they can be integrated in the Industrial IT architecture in a ‘plug and produce’ manner.

Именно поэтому все наши новые изделия и технологии выпускаются в варианте, совместимом с архитектурой IndustrialIT, что означает их способность к интеграции с этой архитектурой по принципу "подключи и производи".

We are excited to present in this issue of ABB Review some of our R&D work and a selection of achievements in such a vital area of our business as Automation.

Мы рады представить в настоящем номере "АББ ревю" некоторые из наших научно-исследовательских разработок и достижений в такой жизненно важной для нашего бизнеса области, как автоматика.

R&D investment in our corporate technology programs is the foundation on which our product and system innovation is built.

Вклад наших разработок в общекорпоративные технологические программы группы АББ служит основой для реализации новых технических решений в создаваемых нами устройствах и системах.

Examples abound in the areas of control engineering, MEMS, wireless communication, materials – and, last but not least, software technologies. Enjoy reading about them.

Это подтверждается многочисленными примерами из области техники управления, микроэлектромеханических систем, ближней радиосвязи, материаловедения и не в последнюю очередь программотехники. Хотелось бы пожелать читателю получить удовольствие от чтения этих материалов.
