Robert Garbe
Robert Hermann Garbe (pronounced 'Garber') (9 January 1847 – 23 May 1932) was a German railway engineer and chief engineer of the Berlin division in the Prussian state railways from 1895 to 1917. He was especially known for his steam locomotive designs and is described as one of the greatest authorities on the locomotive. He was the first to suggest the use of superheated steam, universally. However, he saw superheated steam as competing with other innovations such as double expansion compound steam engines (he held a grudge against Hannover's August Borries that his pupil Richard Paul Wagner inherited) or combustion chambers. His designs were, on the one hand, simple to maintain and operate; on the other hand, he blocked innovations that every other pre-Reichsbahn state railway used successfully. He held the belief that two coupled axles were enough for any express engine (his masterpiece being the Prussian S 6 class) and trailing axles as in the "Pacific" configuration were ...

Berlin
Berlin ( , ) is the capital and largest city of Germany by both area and population. Its 3.7 million inhabitants make it the European Union's most populous city, according to population within city limits. One of Germany's sixteen constituent states, Berlin is surrounded by the State of Brandenburg and contiguous with Potsdam, Brandenburg's capital. Berlin's urban area, which has a population of around 4.5 million, is the second most populous urban area in Germany after the Ruhr. The Berlin-Brandenburg capital region has around 6.2 million inhabitants and is Germany's third-largest metropolitan region after the Rhine-Ruhr and Rhine-Main regions. Berlin straddles the banks of the Spree, which flows into the Havel (a tributary of the Elbe) in the western borough of Spandau. Among the city's main topographical features are the many lakes in the western and southeastern boroughs formed by the Spree, Havel and Dahme, the largest of which is Lake Müggelsee. Due to its l ...

People From The Province Of Silesia
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of per ...

Businesspeople From Brandenburg
A businessperson, businessman, or businesswoman is an individual who has founded, owns, or holds shares in (including as an angel investor) a private-sector company. A businessperson undertakes activities (commercial or industrial) for the purpose of generating cash flow, sales, and revenue by using a combination of human, financial, intellectual, and physical capital with a view to fueling economic development and growth. History Prehistoric period: Traders Since a "businessman" can mean anyone in industry or commerce, businesspeople have existed as long as industry and commerce have existed. "Commerce" can simply mean "trade", and trade has existed through all of recorded history. The first businesspeople in human history were traders or merchants. Medieval period: Rise of the merchant class Merchants emerged as a "class" in medieval Italy (compare, for example, the Vaishya, the traditional merchant caste in Indian society). Between 1300 and 1500, modern accountin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

1932 Deaths
Year 193 ( CXCIII) was a common year starting on Monday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Sosius and Ericius (or, less frequently, year 946 ''Ab urbe condita''). The denomination 193 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Compound Locomotive
A compound locomotive is a steam locomotive which is powered by a compound engine, a type of steam engine where steam is expanded in two or more stages. The locomotive was only one application of compounding. Two and three stages were used in ships, for example. Compounding became popular for railway locomotives from the early 1880s and by the 1890s were becoming common. Large numbers were constructed, mostly two- and four-cylinder compounds, in France, Germany, Austria, Hungary, and the United States. It declined in popularity due to maintenance issues and because superheating provided similar efficiencies at lower cost. Nonetheless, compound Mallets were built by the Norfolk and Western Railway right up to 1952. Introduction In the usual arrangement for a compound engine the steam is first expanded in one or two high-pressure ''(HP)'' cylinders, then having given up some heat and lost some pressure, it exhausts into a larger-volume low-pressure ''(LP)'' cylinder, (or two, - or ...

Superheating
In thermodynamics, superheating (sometimes referred to as boiling retardation, or boiling delay) is the phenomenon in which a liquid is heated to a temperature higher than its boiling point, without boiling. This is a so-called ''metastable state'' or ''metastate'', where boiling might occur at any time, induced by external or internal effects.Debenedetti, P.G.Metastable Liquids: Concepts and Principles; Princeton University Press: Princeton, NJ, USA, 1996.Maris, H., Balibar, S. (2000"Negative Pressures and Cavitation in Liquid Helium"Physics Today 53, 29 Superheating is achieved by heating a homogeneous substance in a clean container, free of nucleation sites, while taking care not to disturb the liquid. This may occur by microwaving water in a very smooth container. Disturbing the water may cause an unsafe eruption of hot water and result in burns. Cause Water is said to "boil" when bubbles of water vapor grow without bound, bursting at the surface. For a vapor bubble to e ...

Kassel
Kassel (; in Germany, spelled Cassel until 1926) is a city on the Fulda River in northern Hesse, Germany. It is the administrative seat of the Regierungsbezirk Kassel and the district of the same name and had 201,048 inhabitants in December 2020. The former capital of the state of Hesse-Kassel has many palaces and parks, including the Bergpark Wilhelmshöhe, which is a UNESCO World Heritage Site. Kassel is also known for the '' documenta'' exhibitions of contemporary art. Kassel has a public university with 25,000 students (2018) and a multicultural population (39% of the citizens in 2017 had a migration background). History Kassel was first mentioned in 913 AD, as the place where two deeds were signed by King Conrad I. The place was called ''Chasella'' or ''Chassalla'' and was a fortification at a bridge crossing the Fulda river. There are several yet unproven assumptions of the name's origin. It could be derived from the ancient ''Castellum Cattorum'', a castle of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wilhelm Schmidt (engineer)
Wilhelm Schmidt, known as Hot Steam Schmidt (German: ''Heißdampf-Schmidt'') (1858–1924) was a German engineer and inventor who achieved the breakthrough in the development of superheated steam technology for steam engines. Wilhelm Schmidt was born in Wegeleben in the Prussian Province of Saxony on 18 February 1858. Education At school Wilhelm Schmidt had difficulties with reading, writing and arithmetic, a case of dyslexia. For example, he was unable to recite the alphabet without hesitation all his life. Nor could he memorise poetry or prose. He developed a passion for drawing, however, and for machines. Career Schmidt began his professional career as a machine fitter. He studied at the technical high school in Dresden under Gustav Zeuner. Superheated steam In 1883 he took a post as a civil engineer in Kassel, where he developed superheated steam technology to the point where it could be practically used. In 1908 he transferred his home and the base of his firm to Be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rummelsburg
Rummelsburg () is a subdivision or neighborhood (''Ortsteil'') of the borough (''Bezirk'') of Lichtenberg of the German capital, Berlin. History Rummelsburg was founded in 1669.
