2 an del' wissenschaftlichen und konstruktiven Durchbildung del' Dampfmaschine haben eine groBe Zahl von Gelehrten und prak- tischen Ingenieuren gearbeitet, so daB dieselbe auf del' Hohe ihrer Entwicklung steht. Eine groBere Warmeausnutzung als jetzt die beste Verbundmaschine gibt, ist von einer Dampf- mas chine nicht mehr zu erwarten. Diese vorziigliche Durchbildung kommt del' Dampfmaschine bei dem scharfen Wettstreit, del' im letzten J ahrzehnt auf dem Gebiete del' Kraftmaschinen entbrannt ist, sehr zustatten. Wahrend die Dampfmaschine ja lange Zeit hindurch auf diesem Gebiete alleinherrschend war, ist ihr jetzt eine gefahrliche Kon- kurrenz erwachsen in del' Verbrennungsmaschine. Ganz all- gemein betrachtet ist ja die Art del' Energiegewinnung aus del' Kohle wesentlich einfacher, wenn wir die Kohle in einem Ge- nerator vergasen und das Gas in einer Verbrennungsmaschine zur Wirkung bringen, als wenn wir die in del' Kohle enthaltene Warme zunachst in gespannten Dampf umwandeln und diesen in del' Dampfmaschine arbeiten lassen. Del' auBerst einfache Generator mit dem Gasreiniger steht hiel' del' wesentlich um- fangreicheren und teureren Kesselanlage mit den zugehorigen Speisepumpen, Wasserreiniger, Vorwarmer odeI' Dberhitzcr und Schornstein gegeniiber, und es unterliegt keinem Zweifel, daB auch die Bedienung einer Generatoranlage viel einfacher und darum billiger ist, als diejenige einer gleichwertigen Kessel- anlage. AuBerdem ist die Warmeausnutzung in del' Gas- maschine groBer als in del' Dampfmaschine. Wahrend in del' Dampfmaschine im giinstigsten Fane eine Warmeausnutzung von rd. 4000 cal pro eff. Pferdekraftstunde zu erreichen ist, bezogen auf die Dampfwarme, kommt eine gute Verbrennungs- maschine mit 2400 cal pro eff.

sich ungemein zahlreiche Hilfsmittel der Vorlesung und der Forscherarbeit zusammenbauen lassen, und sie erhielt den Namen eines physikalischen Baukastens mit Recht, da sie an Vielgestaltigkeit der von ihr ermoglichten Zusammenstellungen dem Baukasten des Kindes am ersten vergleichbar ist. Die folgenden Blatter sollen dazu dienen, die Stucke des physikalischen Baukastens zu beschreiben und von ihrer vielseitigen Verwendbarkeit eine Vorstellung zu geben. Bei der Durcharbeitung des physikalischen Baukastens wurde ich unterstutzt von der Firma Georg Beck & Cie. in Berlin-Rummelsburg, Hauptstr. 4, die nunmehr auch die Herstellung der Apparate fUr den Verkauf ubernommen hat und durch ihre Schutzmarke die sorgfaltige und meinen Angaben entsprechende Ausfiihrung verburgt. Eine groGe HiUe, die ich mit besonderem Dank hervorhebe, war es mir auch, daG Herr Professor Bornstein durch sofortige Verwendung vieler der im folgenden zu beschreibenden Apparate in seiner groG en Experimentalvorlesung und in den Ubungen mir reiche Gelegenheit gab, die Stucke im Gebrauch zu erproben und durchzuarbeiten.

Es konnte vielleicht auffallend erscheinen, dass liber einen in der Literatur so wenig beachteten Gegenstand, wie es bisher die Drahtseile waren, ein ganzes Buch herausgegeben werden kann. Es wird dies urn so auffallender sein, wenn ich versichere, dass die zwolf Capitel dieses Buches durchaus nichts Ueberfllissiges enthalten, ja an zahlreichen Stell en ziemlich geddngt sind, derart, dass liber so manche Zeile und liber so manche Spalte der vorhandenen sehr zahlreichen Tabellen nach der bisherigen Gepflogenheit ganze Aufsatze hatten geschrieben werden konnen! Der bedeutende Umfang des Buches bei alIer Gedrangtheit des Stoffes wird dadurch erklarlich und gerechtfertigt sein, dass sich der Verfasser das Zie1 setzte, nach dem Wortlaute des Titels "Alles N othwendige zttr richtigenBeurtheilunfl. Construction u, nd Berechnung del' Drahtseile" den Interessenten - und zwar sowohl den Theoretikern als auch den Practikern - zu bieten. Diese erschopfende Behandlung befolgt im Wesentlichen den theoretischen Weg, welcher auch der einzig richtige und verlassliche ist, wenn er sich - wie dies hier der Fall - in AHem und Jedem auf die Thatsachen der Anwendung und auf verstandig durchgefiihrte Versuche stlitzt. Durch eine solche Theorie kommt dann so Manches zum Vorschein, was unfehlbar richtig sein muss, wenn es auch bisher verhlillt, weil empirisch nicht leicht greifbar war l wie z. B. so mancher derbe Constructionsfehler l so manche verfehlte Auffassung. Dergleichen thatsachliche Verirrungen werden hier auch wirklich aufgedeckt. Vorwort.

In vorliegendem Buche iibergebe ich das Ergebniss einer Reihe practischer Arbeiten und theoretischer U ntersuehungen tiber Dynamomasehillen, zu einem geschlossenen Ganzen zu- sammengesteIlt, der Oeffentlichkeit. leh habe in derselben die Gleiehstrom-Dynamomasehinen in ihrer Wirkungsweise nach einer neuen Anschauung erkHi.rt und eine Theorie derselben, die in letzter Linie die Voraus- bestimmung alIer Gleiehstrom-Dynamomaschinen ermoglieht, aufgestellt. Die Thatsache, dass ich bei Begriindung meiner Firma Fritsche & Pischon den Dynamomaschinenbau nieht durch kostspielige und zeitraubende Versuche einleiten konnte, und doeh die zwingende Nothwendigkeit vorlag, aIles Material neu zu beschaffen, veranlasste mieh auf Grund meiner im Laufe del' Jahre gesammelten Erfahrungen im Maschinenbau die Dynamomasehinen von einem anderen, vom bisherigen ab- weiehenden, Standpunkte ans zu betraehten. Mein Bestreben ging dahin, die Moglichkeit zu schaffen, die Leistung und Grosse einer Dynamomasehine vorauszubestimmen. Beim Erforsehen del' Ursaehen, welche die Wirkung einer Dynamomaschine bestimmen, findet man, dass die elektrischen Leistungen einer Dynamomasehine nul' dureh Bewegungen entstehen, namlieh durch Bewegung von Leitern im magne- tisehen Felde, dessen Eigensehaften wiederum auf die Be- wegung del' magnetischen Strome zuriickzufiihren sind. Nur diese beiden Bewegungen sind fiir den Effect, die Umwandlung der mechanisehen Arbeit in elektrische Arbeit, massgebend. Um den Zusammenhang zu erkliiren, del' diesem, durch zwei Bewegungen erzielten Effect zu Grunde liegt, habe ieh Vorwort. VI nach den Gl'undsatzen der Phoronomie, bezw. der mechanischen Bewegungslehre, eine Erklarung der Vorgange in einer Dynamo- maschine gegeben. Meine Theorie beruht auf der Ampere'schen Auffassung fiber das Wesen des Magnetismus und auf den Satzen del' mechanischen Bewegungslehre.

China was the last country in the world to manufacture and operate steam locomotives. By the early 1980s, there were an estimated 10,000 operational steam locomotives in the country, but by the 1990s, diesel and electric locomotives started to replace them on the main lines and the number in service reduced substantially as the millennium approached. The last steam locomotives were finally withdrawn from China Rail in 2003. After that, some continued to operate heavy freight trains on local railways for a short while, but most were deployed for use on the country's industrial railways, mainly at coal mines and steel works. This trend continued into the first decade of the 21st century, but subsequently, the number of steam engines in service declined substantially and were confined to just a handful of industrial locations. Steam rail operations in China are now facing extinction. The modernisation of the railways with the switch from steam to diesel, the closure of unsafe and loss-making collieries and China's drive to reduce pollution and combat climate change from burning coal, have all conspired towards the demise of the industrial lines operating steam in China. This book looks at the last of the standard-gauge steam operations in China, including Sandaoling, the last steam-worked opencast coal mine in the world; Fuxin, a coal-mining city in Liaoning Province, which until recently, operated the largest surviving fleet of SY locomotives; Baiyin, in Gansu Province, which operated some of the last steam-hauled passenger trains in the world; and Wu Jiu, a remote coal-mining outpost in Inner Mongolia. Beautifully illustrated with over 120 colour photographs and a description of the operations, this is a striking portrait of the last of the world's operating steam trains.

The Rolls-Royce Merlin is the most recognisable aero engine in the world. It powered the Battle of Britain aircraft, the Spitfire and Hurricane, as they defended the shores of Britain against the Luftwaffe, foiling Hitler's plans to invade in summer 1940. It also powered the Lancasters and Halifaxes of Bomber Command as they went on their missions of destruction to the German heartland. And the 'wooden wonder', the Mosquito, was powered by the Merlin, its pinpoint bombing accuracy and reconnaissance work proving vital to the war effort. For the Americans, the Merlin was the power plant of the Mustang escort fighter that protected the US Air Force B-17 Flying Fortress and B-29 Super Fortress bombers on their daylight raids to the enemy. The P-51 was also used in the North African, Mediterranean and Pacific theatres. So the Merlin worked day and night to secure the eventual Allied victory. It has rightfully been described as the most significant aircraft piston engine in history and in the twenty-first century its distinctive 'drone' can still be heard over England as the Battle of Britain Memorial Flight take to the air on special occasions - most recently on the centenary of the RAF - with its Lancaster leading the Merlin-powered Spitfires and Hurricanes in formation. Retired military and commercial pilot Gordon Wilson tells the human story of the development of the engine and its operational use during the war, featuring the voices of air crew who relied on this technological tour de force.

This book presents the papers from the latest international conference, following on from the highly successful previous conferences in this series held regularly since 1978. Papers cover all current and novel aspects of turbocharging systems design for boosting solutions for engine downsizing. The focus of the papers is on the application of turbocharger and other pressure charging devices to spark ignition (SI) and compression ignition (CI) engines in the passenger car and commercial vehicles. Novel boosting solutions for diesel engines operating in the industrial and marine market sectors are also included. The current emission legislations and environmental trends for reducing CO2 and fuel consumption are the major market forces in the transport (land and marine) and industry sectors. In these market sectors the internal combustion engine is the key product where downsizing is the driver for development for both SI and CI engines in the passenger car and commercial vehicle applications. The more stringent future market forces and environmental considerations mean more stringent engine downsizing, thus, novel systems are required to provide boosting solutions including hybrid, electric-motor and exhaust waste energy recovery systems for high efficiency, response, reliability, durability and compactness etc. For large engines the big challenge is to enhance the high specific power and efficiency whilst reducing emission levels (Nox and Sox) with variable quality fuels. This will require turbocharging systems for very high boost pressure, efficiency and a high degree of system flexibility.

Hybrid drives and the operation of hybrid vehicles are characteristic of contemporary automotive technology. Together with the electronic driver assistant systems, hybrid technology is of the greatest importance and both cannot be ignored by today s car drivers. This technical reference book provides the reader with a firsthand comprehensive description of significant components of automotive technology. All texts are complemented by numerous detailed illustrations."

Genius' is an over-used, but rarely-accurate, description applied to remarkable figures. In the case of Richard Trevithick, however, its use is not only apt, but could even be regarded as something of an understatement. Philip Hosken's 'Genius' offers a perfect introduction to the great engineer. Combining detailed and original research, the result is a clearly stated, unbiased and readable account of his life and achievements. From childhood and early motivation, through feverish experimentation and frustration, to the eventual triumph of his revolutionary high pressure cylindrical boiler, 1801 road engine and the world's first railway locomotive, the author explains how and why Trevithick became a giant of invention and innovation. Laying to rest myths regurgitated by less-diligent writers, while not neglecting the major contributions to the story of Papin, Newcomen, Savery and others, Hosken employs the kind of scientific rigour which the protagonist of his book might recognise and approve. If you only read one book about Richard Trevithick, make sure it's this one.

Of all the many types of machine elements which exist today, gears are among the most commonly used. The basic idea of a wheel with teeth is extremely simple, and dates back several thousand years. It is obvious to any observer that one gear drives another by means of the meshing teeth, and to the person who has never studied gears, it might seem that no further explanation is required. It may therefore come as a surprise to discover the large quantity of geometric theory that exists on the subject of gears, and to find that there is probably no branch of mechanical engineering where theory and practice are more closely linked. Enormous improvements have been made in the performance of gears during the last two hundred years or so, and this has been due principally to the careful attention given to the shape of the teeth. The theoretical shape of the tooth profile used in most modern gears is an involute. When precision gears are cut by modern gear-cutting machines, the accuracy with which the actual teeth conform to their theoretical shape is quite remarkable, and far exceeds the accuracy which is attained in the manufacture of most other types of machine elements. The first part of this book deals with spur gears, which are gears with teeth that are parallel to the gear axis. The second part describes helical gears, whose teeth form helices about the gear axis.

The original Air Engines (also known as a heat, hot air, caloric, or Stirling engines), predated the modern internal combustion engine. This early engine design always had great potential for high efficiency/low emission power generation. However, the primary obstacle to its practical use in the past has been the lack of sufficiently heat-resistant materials. This obstacle has now been eliminated due to the higher strength of modern materials and alloys. Several companies in the U.S. and abroad are successfully marketing new machines based on the Air Engine concept. Allan Organ and Theodor Finkelstein are two of the most respected researchers in the field of Air Engines. Finkelstein is considered a pioneer of Stirling cycle simulation. The historical portion of the book is based on four famous articles he published in 1959. The rest of the chapters assess the development of the air engine and put it in the modern context, as well as investigate its future potential and applications. The audience for this book includes mechanical engineers working in power related industries, as well as researchers, academics, and advanced students concerned with recent developments in power generation.

The book presents select proceedings of the 8th International and 29th All India Manufacturing Technology, Design and Research (AIMTDR 2021) conference. It covers recent advances in the realms of electro- physical and chemical machining, machining optimization, surface morphology and sustainable machining.

Windmills have been in existence for over 800 years and although only a fraction of those that once ground corn, pumped water and provided power for industry and agriculture, now survive. Among the most important features of these survivors are the variations in design that have come about through their different origins, the use of local materials in their construction, and the influence of millwrights and millers - those who built and worked them - in different parts of the country. Understanding these variations provides important clues to the need to protect and maintain windmills, the continued survival of which allows a fascinating insight into the historic use of renewable energy, the development of engineering, and the processing of grain, for flour and bread, as well as other essential products.
