Landshut
Landshut (; ) is a town in Bavaria, Germany, on the banks of the Isar, River Isar. Landshut is the capital of Lower Bavaria, one of the seven administrative regions of the Free state (government), Free State of Bavaria, and the seat of the surrounding district. With a population of more than 75,000, Landshut is the largest city in Lower Bavaria, followed by Passau and Straubing. The town, called City of the Three Helmets (), is known for its picturesque Gothic architecture, Gothic old town and the Landshut Wedding, a full-tilt medieval festival. The cityscape is dominated by the St. Martin's Church, Landshut, St. Martin's Basilica and Trausnitz Castle high above the old town. Close to Munich and Franz Josef Strauss International Airport, Landshut is industrialized (BMW, ebm-papst, Schott AG, Schott), has a low unemployment rate and is among the richest towns in Bavaria. Geography Landshut lies in the Alpine foothills. The River Isar runs through the city and splits in two in t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Centrifugal Fan
A centrifugal fan is a mechanical device for moving air or other gases in a direction perpendicular to the axis of rotation of the fan. Centrifugal fans often contain a ducted fan, ducted housing to direct outgoing air in a specific direction or across a heat sink; such a fan is also called a blower, blower fan, or squirrel-cage fan (because it looks like a hamster wheel). Tiny ones used in computers are sometimes called biscuit blowers. These fans move air from the rotating inlet of the fan to an outlet. They are typically used in ducted applications to either draw air through ductwork/heat exchanger, or push air through similar impellers. Compared to standard axial fans, they can provide similar air movement from a smaller fan package, and overcome higher Fluid dynamics, resistance in air streams. Centrifugal fans use the kinetic energy of the impellers to move the air stream, which in turn moves against the resistance caused by ducts, dampers and other components. Centrifu ...

GmbH & Co
(; ) is a type of Juridical person, legal entity in German-speaking countries. It is equivalent to a (Sàrl) in the Romandy, French-speaking region of Switzerland and to a (Sagl) in the Ticino, Italian-speaking region of Switzerland. It is an entity broadly equivalent to the private limited company (PLC) in the United Kingdom and many Commonwealth of Nations, Commonwealth countries, and the limited liability company (LLC) in the United States. The name of the GmbH form emphasizes that the owners (, also known as members) of the entity are not personally liable for the company's debts. GmbHs are considered legal persons under German, Swiss, and Austrian law. Other variations include mbH (used when the term is part of the company name itself), and gGmbH () for non-profit companies. The GmbH has become the most common corporation form in Germany because the AG (), the other major company form corresponding to a stock corporation, was much more complicated to form and operate un ...

Cleanroom
A cleanroom or clean room is an engineered space that maintains a very low concentration of airborne particulates. It is well-isolated, well-controlled from contamination, and actively cleansed. Such rooms are commonly needed for scientific research and in industrial production for all nanoscale processes, such as semiconductor device manufacturing. A cleanroom is designed to keep everything from dust to airborne organisms or vaporised particles away from it, and so from whatever material is being handled inside it. A cleanroom can also prevent the escape of materials. This is often the primary aim in hazardous biology, nuclear work, pharmaceutics, and virology. Cleanrooms typically come with a cleanliness level quantified by the number of particles per cubic meter at a predetermined molecule measure. The ambient outdoor air in a typical urban area contains 35,000,000 particles for each cubic meter in the size range 0.5 μm and bigger, equivalent to an ISO 9 certified c ...

Nürnberger Nachrichten
The Nürnberger Nachrichten (NN) was originally a local daily in the Nuremberg-Erlangen-Fürth area. With its regional editions, it covers the whole of Middle Franconia and parts of Upper Franconia and the Upper Palatinate and is one of Germany's large regional newspapers. The ''Nürnberger Zeitung'' belongs to the same group but is editorially independent. History and profile The ''Nürnberger Nachrichten'' (NN) was first published on 11 October 1945. Its founder, Joseph E. Drexel, was granted licence No. 3 for newspaper publication by the occupying power, the American Military Government in Bavaria. At first, the NN was printed in Zirndorf because it was not possible to find an intact printing plant in Nuremberg, owing to the war damage. In 1945/46 the paper only came out twice a week; from Autumn 1946 to 1949 that increased to three times a week, and subsequently, four times a week. In Autumn 1949, the publishers moved to Nuremberg. It was not until 16 November 1962 that the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bevel Gear
Bevel gears are gears where the axes of the two shafts intersect and the tooth-bearing faces of the gears themselves are conically shaped. Bevel gears are most often mounted on shafts that are 90 degrees apart, but can be designed to work at other angles as well. The pitch surface of bevel gears is a cone, known as a pitch cone. Bevel gears change the axis of rotation of rotational power delivery and are widely used in mechanical settings. Introduction Two important concepts in gearing are pitch surface and pitch angle. The pitch surface of a gear is the imaginary toothless surface that you would have by averaging out the peaks and valleys of the individual teeth. The pitch surface of an ordinary gear is the shape of a cylinder. The pitch angle of a gear is the angle between the face of the pitch surface and the axis. The most familiar kinds of bevel gears have pitch angles of less than 90 degrees and therefore are cone-shaped. This type of bevel gear is called external ...

Spur Gear
Spur gears or straight-cut gears are the simplest type of gear. They consist of a cylinder or disk with teeth projecting radially. Viewing the gear at 90 degrees from the shaft length (side on) the tooth faces are straight and aligned parallel to the axis of rotation. Looking down the length of the shaft, a tooth's cross section is usually not triangular. Instead of being straight (as in a triangle) the sides of the cross section have a curved form (usually involute and less commonly cycloidal) to achieve a constant drive ratio. Spur gears mesh together correctly only if fitted to parallel shafts. No axial thrust is created by the tooth loads. Spur gears are excellent at moderate speeds but tend to be noisy at high speeds. Spur gear can be classified into two pressure angles, 20° being the current industry standard and 14½° being the former (often found in older equipment). Spur gear teeth are manufactured as either involute In mathematics, an involute (also known as an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Epicyclic Gearing
An epicyclic gear train (also known as a planetary gearset) is a gear reduction assembly consisting of two gears mounted so that the center of one gear (the "planet") revolves around the center of the other (the "sun"). A carrier connects the centers of the two gears and rotates, to carry the planet gear(s) around the sun gear. The planet and sun gears mesh so that their pitch circles roll without slip. If the sun gear is held fixed, then a point on the pitch circle of the planet gear traces an epicycloid curve. An epicyclic gear train can be assembled so the planet gear rolls on the inside of the pitch circle of an outer gear ring, or ring gear, sometimes called an ''annulus gear''. Such an assembly of a planet engaging both a sun gear and a ring gear is called a planetary gear train.J. J. Uicker, G. R. Pennock and J. E.

Frankfurter Allgemeine Zeitung
The (; ''FAZ''; "Frankfurt General Newspaper") is a German newspaper founded in 1949. It is published daily in Frankfurt and is considered a newspaper of record for Germany. Its Sunday edition is the ''Frankfurter Allgemeine Sonntagszeitung'' (; ''FAS''). The paper runs its own network of correspondents. Its editorial policy is not determined by a single editor, but cooperatively by four editors. History The first edition of the ''FAZ'' appeared on 1 November 1949; its founding editors were Hans Baumgarten, Erich Dombrowski, Karl Korn, Paul Sethe and Erich Welter. Welter acted as editor until 1980. Some editors had worked for the moderate '' Frankfurter Zeitung'', which had been banned in 1943. However, in their first issue, the ''FAZ'' editorial expressly refuted the notion of being the earlier paper's successor, or of continuing its legacy: Until 30 September 1950, the ''FAZ'' was printed in Mainz. Traditionally, many of the headlines in the ''FAZ'' were styled in bl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
