No “Chimney” effect
Continuous air spaces inside I-LINE busway housing are closed off with special barriers to help prevent the spread of smoke and gases in the event of a fire in the area of the busway installation. This standard internal barrier allows busway to extend through wall or floors without creating open space for a “chimney effect” fire path.
[Schneider Electric]Отсутствие эффекта тяги
Пространство внутри кожуха шинопровода I-LINE перекрыто специальными перегородками, предотвращающими распространение дыма и газов при возникновении пожара в месте расположения шинопровода. Эти стандартные внутренние перегородки позволяют прокладывать шинопровод через стены и перекрытия, так, что он не будет создавать эффекта тяги, способствующего распространению огня.

52 Booth, Henry
[br]b. 4 April 1789 Liverpool, Englandd. 28 March 1869 Liverpool, England[br]English railway administrator and inventor.[br]Booth followed his father as a Liverpool corn merchant but had great mechanical aptitude. In 1824 he joined the committee for the proposed Liverpool \& Manchester Railway (L \& MR) and after the company obtained its Act of Parliament in 1826 he was appointed Treasurer.In 1829 the L \& MR announced a prize competition, the Rainhill Trials, for an improved steam locomotive: Booth, realizing that the power of a locomotive depended largely upon its capacity to raise steam, had the idea that this could be maximized by passing burning gases from the fire through the boiler in many small tubes to increase the heating surface, rather than in one large one, as was then the practice. He was apparently unaware of work on this type of boiler even then being done by Marc Seguin, and the 1791 American patent by John Stevens. Booth discussed his idea with George Stephenson, and a boiler of this type was incorporated into the locomotive Rocket, which was built by Robert Stephenson and entered in the Trials by Booth and the two Stephensons in partnership. The boiler enabled Rocket to do all that was required in the trials, and far more: it became the prototype for all subsequent conventional locomotive boilers.After the L \& MR opened in 1830, Booth as Treasurer became in effect the general superintendent and was later General Manager. He invented screw couplings for use with sprung buffers. When the L \& MR was absorbed by the Grand Junction Railway in 1845 he became Secretary of the latter, and when, later the same year, that in turn amalgamated with the London \& Birmingham Railway (L \& BR) to form the London \& North Western Railway (L \& NWR), he became joint Secretary with Richard Creed from the L \& BR.Earlier, completion in 1838 of the railway from London to Liverpool had brought problems with regard to local times. Towns then kept their own time according to their longitude: Birmingham time, for instance, was 7¼ minutes later than London time. This caused difficulties in railway operation, so Booth prepared a petition to Parliament on behalf of the L \& MR that London time should be used throughout the country, and in 1847 the L \& NWR, with other principal railways and the Post Office, adopted Greenwich time. It was only in 1880, however, that the arrangement was made law by Act of Parliament.[br]Bibliography1835. British patent no. 6,814 (grease lubricants for axleboxes). 1836.

53 Branca, Giovanni de
SUBJECT AREA: Steam and internal combustion engines[br]b. 1571 Italyd. 1640 Italy[br]Italian architect who proposed what has been suggested as an early turbine, using a jet of steam to turn a wheel.[br]Branca practised architecture at Loretto. In 1629 he published Le Machine: volume nuovo et di molto artificio, in which he described various mechanisms. One was the application of rolls for working copper, lead or the precious metals gold and silver. The rolls were powered by a form of smokejack with the gases from the fire passing up a long tube forming a chimney which, through gearing, turned the rolls. Another device used a jet of steam from a boiler issuing from a mouthpiece shaped like the head of a person to impinge upon blades around the circumference of a horizontal wheel, connected through triple reduction gearing to drop stamps, for pounding drugs. This was a form of impulse turbine and has been claimed as the first machine worked by steam to do a particular operation since Heron's temple doors.[br]Further ReadingH.W.Dickinson, 1938, A Short History of the Steam Engine, Cambridge University Press (includes a description and picture of the turbine).C.Singer (ed.), 1957, A History of Technology, Vols III and IV, Oxford University Press (provides notes on Branca).RLH -
54 Carnot, Nicolas Léonard Sadi
SUBJECT AREA: Steam and internal combustion engines[br]b. 1 June 1796 Paris, Franced. 24 August 1831 Paris, France[br]French laid the foundations for modern thermodynamics through his book Réflexions sur la puissance motrice du feu when he stated that the efficiency of an engine depended on the working substance and the temperature drop between the incoming and outgoing steam.[br]Sadi was the eldest son of Lazare Carnot, who was prominent as one of Napoleon's military and civil advisers. Sadi was born in the Palais du Petit Luxembourg and grew up during the Napoleonic wars. He was tutored by his father until in 1812, at the minimum age of 16, he entered the Ecole Polytechnique to study stress analysis, mechanics, descriptive geometry and chemistry. He organized the students to fight against the allies at Vincennes in 1814. He left the Polytechnique that October and went to the Ecole du Génie at Metz as a student second lieutenant. While there, he wrote several scientific papers, but on the Restoration in 1815 he was regarded with suspicion because of the support his father had given Napoleon. In 1816, on completion of his studies, Sadi became a second lieutenant in the Metz engineering regiment and spent his time in garrison duty, drawing up plans of fortifications. He seized the chance to escape from this dull routine in 1819 through an appointment to the army general staff corps in Paris, where he took leave of absence on half pay and began further courses of study at the Sorbonne, Collège de France, Ecole des Mines and the Conservatoire des Arts et Métiers. He was inter-ested in industrial development, political economy, tax reform and the fine arts.It was not until 1821 that he began to concentrate on the steam-engine, and he soon proposed his early form of the Carnot cycle. He sought to find a general solution to cover all types of steam-engine, and reduced their operation to three basic stages: an isothermal expansion as the steam entered the cylinder; an adiabatic expansion; and an isothermal compression in the condenser. In 1824 he published his Réflexions sur la puissance motrice du feu, which was well received at the time but quickly forgotten. In it he accepted the caloric theory of heat but pointed out the impossibility of perpetual motion. His main contribution to a correct understanding of a heat engine, however, lay in his suggestion that power can be produced only where there exists a temperature difference due "not to an actual consumption of caloric but to its transportation from a warm body to a cold body". He used the analogy of a water-wheel with the water falling around its circumference. He proposed the true Carnot cycle with the addition of a final adiabatic compression in which motive power was con sumed to heat the gas to its original incoming temperature and so closed the cycle. He realized the importance of beginning with the temperature of the fire and not the steam in the boiler. These ideas were not taken up in the study of thermodynartiics until after Sadi's death when B.P.E.Clapeyron discovered his book in 1834.In 1824 Sadi was recalled to military service as a staff captain, but he resigned in 1828 to devote his time to physics and economics. He continued his work on steam-engines and began to develop a kinetic theory of heat. In 1831 he was investigating the physical properties of gases and vapours, especially the relationship between temperature and pressure. In June 1832 he contracted scarlet fever, which was followed by "brain fever". He made a partial recovery, but that August he fell victim to a cholera epidemic to which he quickly succumbed.[br]Bibliography1824, Réflexions sur la puissance motrice du feu; pub. 1960, trans.

55 Chapelon, André
[br]b. 26 October 1892 Saint-Paul-en-Cornillon, Loire, Franced. 29 June 1978 Paris, France[br]French locomotive engineer who developed high-performance steam locomotives.[br]Chapelon's technical education at the Ecole Centrale des Arts et Manufactures, Paris, was interrupted by extended military service during the First World War. From experience of observing artillery from the basket of a captive balloon, he developed a method of artillery fire control which was more accurate than that in use and which was adopted by the French army.In 1925 he joined the motive-power and rolling-stock department of the Paris-Orléans Railway under Chief Mechanical Engineer Maurice Lacoin and was given the task of improving the performance of its main-line 4–6–2 locomotives, most of them compounds. He had already made an intensive study of steam locomotive design and in 1926 introduced his Kylchap exhaust system, based in part on the earlier work of the Finnish engineer Kyläla. Chapelon improved the entrainment of the hot gases in the smokebox by the exhaust steam and so minimized back pressure in the cylinders, increasing the power of a locomotive substantially. He also greatly increased the cross-sectional area of steam passages, used poppet valves instead of piston valves and increased superheating of steam. PO (Paris-Orléans) 4–6–2s rebuilt on these principles from 1929 onwards proved able to haul 800-ton trains, in place of the previous 500-ton trains, and to do so to accelerated schedules with reduced coal consumption. Commencing in 1932, some were converted, at the time of rebuilding, into 4–8–0s to increase adhesive weight for hauling heavy trains over the steeply graded Paris-Toulouse line.Chapelon's principles were quickly adopted on other French railways and elsewhere.H.N. Gresley was particularly influenced by them. After formation of the French National Railways (SNCF) in 1938, Chapelon produced in 1941 a prototype rebuilt PO 2–10–0 freight locomotive as a six-cylinder compound, with four low-pressure cylinders to maximize expansive use of steam and with all cylinders steam-jacketed to minimize heat loss by condensation and radiation. War conditions delayed extended testing until 1948–52. Meanwhile Chapelon had, by rebuilding, produced in 1946 a high-powered, three-cylinder, compound 4–8–4 intended as a stage in development of a proposed range of powerful and thermally efficient steam locomotives for the postwar SNCF: a high-speed 4–6–4 in this range was to run at sustained speeds of 125 mph (200 km/h). However, plans for improved steam locomotives were then overtaken in France by electriflcation and dieselization, though the performance of the 4–8–4, which produced 4,000 hp (3,000 kW) at the drawbar for the first time in Europe, prompted modification of electric locomotives, already on order, to increase their power.Chapelon retired from the SNCF in 1953, but continued to act as a consultant. His principles were incorporated into steam locomotives built in France for export to South America, and even after the energy crisis of 1973 he was consulted on projects to build improved, high-powered steam locomotives for countries with reserves of cheap coal. The eventual fall in oil prices brought these to an end.[br]Bibliography1938, La Locomotive à vapeur, Paris: J.B.Bailière (a comprehensive summary of contemporary knowledge of every function of the locomotive).Further ReadingH.C.B.Rogers, 1972, Chapelon, Genius of French Steam, Shepperton: Ian Allan.1986, "André Chapelon, locomotive engineer: a survey of his work", Transactions of the Newcomen Society 58 (a symposium on Chapelon's work).Obituary, 1978, Railway Engineer (September/October) (makes reference to the technical significance of Chapelon's work).PJGR -
56 Hero of Alexandria
SUBJECT AREA: Architecture and building, Mechanical, pneumatic and hydraulic engineering, Photography, film and optics, Steam and internal combustion engines[br]fl. c.62 AD Alexandria[br]Alexandrian mathematician and mechanician.[br]Nothing is known of Hero, or Heron, apart from what can be gleaned from the books he wrote. Their scope and style suggest that he was a teacher at the museum or the university of Alexandria, writing textbooks for his students. The longest book, and the one with the greatest technological interest, is Pneumatics. Some of its material is derived from the works of the earlier writers Ctesibius of Alexandria and Philo of Byzantium, but many of the devices described were invented by Hero himself. The introduction recognizes that the air is a body and demonstrates the effects of air pressure, as when air must be allowed to escape from a closed vessel before water can enter. There follow clear descriptions of a variety of mechanical contrivances depending on the effects of either air pressure or heated gases. Most of the devices seem trivial, but such toys or gadgets were popular at the time and Hero is concerned to show how they work. Inventions with a more serious purpose are a fire pump and a water organ. One celebrated gadget is a sphere that is set spinning by jets of steam—an early illustration of the reaction principle on which modern jet propulsion depends.M echanics, known only in an Arabic version, is a textbook expounding the theory and practical skills required by the architect. It deals with a variety of questions of mechanics, such as the statics of a horizontal beam resting on vertical posts, the theory of the centre of gravity and equilibrium, largely derived from Archimedes, and the five ways of applying a relatively small force to exert a much larger one: the lever, winch, pulley, wedge and screw. Practical devices described include sledges for transporting heavy loads, cranes and a screw cutter.Hero's Dioptra describes instruments used in surveying, together with an odometer or device to indicate the distance travelled by a wheeled vehicle. Catoptrics, known only in Latin, deals with the principles of mirrors, plane and curved, enunciating that the angle of incidence is equal to that of reflection. Automata describes two forms of puppet theatre, operated by strings and drums driven by a falling lead weight attached to a rope wound round an axle. Hero's mathematical work lies in the tradition of practical mathematics stretching from the Babylonians through Islam to Renaissance Europe. It is seen most clearly in his Metrica, a treatise on mensuration.Of all his works, Pneumatics was the best known and most influential. It was one of the works of Greek science and technology assimilated by the Arabs, notably Banu Musa ibn Shakir, and was transmitted to medieval Western Europe.[br]BibliographyAll Hero's works have been printed with a German translation in Heronis Alexandrini opera quae supersunt omnia, 1899–1914, 5 vols, Leipzig. The book on pneumatics has been published as The Pneumatics of Hero of Alexandria, 1851, trans. and ed. Bennet Wood-croft, London (facs. repr. 1971, introd.

57 Perkins, Jacob
[br]b. 9 July 1766 Newburyport, Massachusetts, USAd. 30 July 1849 London, England[br]American inventor of a nail-making machine and a method of printing banknotes, investigator of the use of steam at very high pressures.[br]Perkins's occupation was that of a gold-and silversmith; while he does not seem to have followed this after 1800, however, it gave him the skills in working metals which he would continue to employ in his inventions. He had been working in America for four years before he patented his nail-making machine in 1796. At the time there was a great shortage of nails because only hand-forged ones were available. By 1800, other people had followed his example and produced automatic nail-making machines, but in 1811 Perkins' improved machines were introduced to England by J.C. Dyer. Eventually Perkins had twenty-one American patents for a range of inventions in his name.In 1799 Perkins invented a system of engraving steel plates for printing banknotes, which became the foundation of modern siderographic work. It discouraged forging and was adopted by many banking houses, including the Federal Government when the Second United States Bank was inaugurated in 1816. This led Perkins to move to Philadelphia. In the intervening years, Perkins had improved his nail-making machine, invented a machine for graining morocco leather in 1809, a fire-engine in 1812, a letter-lock for bank vaults and improved methods of rolling out spoons in 1813, and improved armament and equipment for naval ships from 1812 to 1815.It was in Philadelphia that Perkins became interested in the steam engine, when he met Oliver Evans, who had pioneered the use of high-pressure steam. He became a member of the American Philosophical Society and conducted experiments on the compressibility of water before a committee of that society. Perkins claimed to have liquified air during his experiments in 1822 and, if so, was the real discoverer of the liquification of gases. In 1819 he came to England to demonstrate his forgery-proof system of printing banknotes, but the Bank of England was the only one which did not adopt his system.While in London, Perkins began to experiment with the highest steam pressures used up to that time and in 1822 took out his first of nineteen British patents. This was followed by another in 1823 for a 10 hp (7.5 kW) engine with only 2 in. (51 mm) bore, 12 in. (305 mm) stroke but a pressure of 500 psi (35 kg/cm2), for which he claimed exceptional economy. After 1826, Perkins abandoned his drum boiler for iron tubes and steam pressures of 1,500 psi (105 kg/cm2), but the materials would not withstand such pressures or temperatures for long. It was in that same year that he patented a form of uniflow cylinder that was later taken up by L.J. Todd. One of his engines ran for five days, continuously pumping water at St Katherine's docks, but Perkins could not raise more finance to continue his experiments.In 1823 one his high-pressure hot-water systems was installed to heat the Duke of Wellington's house at Stratfield Saye and it acquired a considerable vogue, being used by Sir John Soane, among others. In 1834 Perkins patented a compression ice-making apparatus, but it did not succeed commercially because ice was imported more cheaply from Norway as ballast for sailing ships. Perkins was often dubbed "the American inventor" because his inquisitive personality allied to his inventive ingenuity enabled him to solve so many mechanical challenges.[br]Further ReadingHistorical Society of Pennsylvania, 1943, biography which appeared previously as a shortened version in the Transactions of the Newcomen Society 24.D.Bathe and G.Bathe, 1943–5, "The contribution of Jacob Perkins to science and engineering", Transactions of the Newcomen Society 24.D.S.L.Cardwell, 1971, From Watt to Clausius.

58 Priestman, William Dent
SUBJECT AREA: Steam and internal combustion engines[br]b. 23 August 1847 Sutton, Hull, Englandd. 7 September 1936 Hull, England[br]English oil engine pioneer.[br]William was the second son and one of eleven children of Samuel Priestman, who had moved to Hull after retiring as a corn miller in Kirkstall, Leeds, and who in retirement had become a director of the North Eastern Railway Company. The family were strict Quakers, so William was sent to the Quaker School in Bootham, York. He left school at the age of 17 to start an engineering apprenticeship at the Humber Iron Works, but this company failed so the apprenticeship was continued with the North Eastern Railway, Gateshead. In 1869 he joined the hydraulics department of Sir William Armstrong \& Company, Newcastle upon Tyne, but after a year there his father financed him in business at a small, run down works, the Holderness Foundry, Hull. He was soon joined by his brother, Samuel, their main business being the manufacture of dredging equipment (grabs), cranes and winches. In the late 1870s William became interested in internal combustion engines. He took a sublicence to manufacture petrol engines to the patents of Eugène Etève of Paris from the British licensees, Moll and Dando. These engines operated in a similar manner to the non-compression gas engines of Lenoir. Failure to make the two-stroke version of this engine work satisfactorily forced him to pay royalties to Crossley Bros, the British licensees of the Otto four-stroke patents.Fear of the dangers of petrol as a fuel, reflected by the associated very high insurance premiums, led William to experiment with the use of lamp oil as an engine fuel. His first of many patents was for a vaporizer. This was in 1885, well before Ackroyd Stuart. What distinguished the Priestman engine was the provision of an air pump which pressurized the fuel tank, outlets at the top and bottom of which led to a fuel atomizer injecting continuously into a vaporizing chamber heated by the exhaust gases. A spring-loaded inlet valve connected the chamber to the atmosphere, with the inlet valve proper between the chamber and the working cylinder being camoperated. A plug valve in the fuel line and a butterfly valve at the inlet to the chamber were operated, via a linkage, by the speed governor; this is believed to be the first use of this method of control. It was found that vaporization was only partly achieved, the higher fractions of the fuel condensing on the cylinder walls. A virtue was made of this as it provided vital lubrication. A starting system had to be provided, this comprising a lamp for preheating the vaporizing chamber and a hand pump for pressurizing the fuel tank.Engines of 2–10 hp (1.5–7.5 kW) were exhibited to the press in 1886; of these, a vertical engine was installed in a tram car and one of the horizontals in a motor dray. In 1888, engines were shown publicly at the Royal Agricultural Show, while in 1890 two-cylinder vertical marine engines were introduced in sizes from 2 to 10 hp (1.5–7.5 kW), and later double-acting ones up to some 60 hp (45 kW). First, clutch and gearbox reversing was used, but reversing propellers were fitted later (Priestman patent of 1892). In the same year a factory was established in Philadelphia, USA, where engines in the range 5–20 hp (3.7–15 kW) were made. Construction was radically different from that of the previous ones, the bosses of the twin flywheels acting as crank discs with the main bearings on the outside.On independent test in 1892, a Priestman engine achieved a full-load brake thermal efficiency of some 14 per cent, a very creditable figure for a compression ratio limited to under 3:1 by detonation problems. However, efficiency at low loads fell off seriously owing to the throttle governing, and the engines were heavy, complex and expensive compared with the competition.Decline in sales of dredging equipment and bad debts forced the firm into insolvency in 1895 and receivers took over. A new company was formed, the brothers being excluded. However, they were able to attend board meetings, but to exert no influence. Engine activities ceased in about 1904 after over 1,000 engines had been made. It is probable that the Quaker ethics of the brothers were out of place in a business that was becoming increasingly cut-throat. William spent the rest of his long life serving others.[br]Further ReadingC.Lyle Cummins, 1976, Internal Fire, Carnot Press.C.Lyle Cummins and J.D.Priestman, 1985, "William Dent Priestman, oil engine pioneer and inventor: his engine patents 1885–1901", Proceedings of the Institution ofMechanical Engineers 199:133.Anthony Harcombe, 1977, "Priestman's oil engine", Stationary Engine Magazine 42 (August).JBBiographical history of technology > Priestman, William Dent
