Private Company
A privately held company (or simply a private company) is a company whose shares and related rights or obligations are not offered for public subscription or publicly negotiated in the respective listed markets, but rather the company's stock is offered, owned, traded, exchanged privately, or Over-the-counter (finance), over-the-counter. In the case of a closed corporation, there are a relatively small number of shareholders or company members. Related terms are closely-held corporation, unquoted company, and unlisted company. Though less visible than their public company, publicly traded counterparts, private companies have major importance in the world's economy. In 2008, the 441 list of largest private non-governmental companies by revenue, largest private companies in the United States accounted for ($1.8 trillion) in revenues and employed 6.2 million people, according to ''Forbes''.

First Schleswig War
The First Schleswig War (german: Schleswig-Holsteinischer Krieg) was a military conflict in southern Denmark and northern Germany rooted in the Schleswig-Holstein Question, contesting the issue of who should control the Duchies of Schleswig, Holstein and Lauenburg. Ultimately, the Danish side proved victorious with the diplomatic support of the great powers. As the government, merchants, students, landowners and other upper class at the time spoke German, Low German was lingua franca in most of northern Europe at the time, the Germans claim it was mainly German-speaking areas, but the majority of the people were native Danish and Frisian speaking peasants and servants. Their languages would be systematically oppressed by the Germans over the next 100 years. The conflict is known as the Three Years' War ( da, Treårskrigen) in Denmark. In Germany, the war is called the Schleswig-Holstein War (german: Schleswig-Holsteinischer Krieg) but also as the Schleswig-Holstein Upri ...

Rendsburg
Rendsburg ( da, Rendsborg, also ''Rensborg'', nds, Rendsborg, also ''Rensborg'') is a town on the River Eider and the Kiel Canal in the central part of Schleswig-Holstein, Germany. It is the capital of the ''Kreis'' (district) of Rendsburg-Eckernförde. , it had a population of 28,476. History Rendsburg's foundation date is unknown though some form of fortifications was established by Bjørn Svendsen 1099–1100. Rendsburg was first mentioned in 1199. An old form of its name was Reinoldesburch. It became a part of Holstein in the 13th century, but was transferred to Schleswig in 1460. Many times the town passed from Danish to German control and vice versa. In the German-Danish War in 1864 Rendsburg was finally seized by Kingdom of Prussia and Austria. After 1866 the town was annexed by the Kingdom of Prussia. Since that time it has remained part of Germany. Although the Eider is navigable for small craft from its mouth on the North Sea to Rendsburg, the town's importance r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wilhelm Bauer
Wilhelm Bauer (23 December 1822 – 20 June 1875) was a German inventor and engineer who built several hand-powered submarines. Biography Wilhelm Bauer was born in Dillingen in the Kingdom of Bavaria. His father was a sergeant of a Bavarian cavalry regiment. Due to this, after an apprenticeship as a wood turner, Bauer also joined the army. Working as an artillery engineer, he witnessed the German/Danish war for Schleswig-Holstein between 1848 and 1851. Seeing how the Prussian coast was easily blockaded by the Danish navy, Bauer quickly developed a plan to build a new type of submersible ship to help break the blockade. He began studying hydraulics and ship construction. However, before his studies could get very far, the troops of the German Confederation decided to withdraw and surrendered Schleswig-Holstein to Denmark. However, Bauer was determined to realize his plan at any cost and left the Bavarian Army to join the forces of Schleswig-Holstein. It proved very hard for ...

Brandtaucher
''Brandtaucher'' ( German for ''Fire-diver'') was a submersible designed by the Bavarian inventor and engineer Wilhelm Bauer and built by Schweffel & Howaldt in Kiel for Schleswig-Holstein's Flotilla (part of the ''Reichsflotte'') in 1850. The ''Brandtaucher'' is the oldest known surviving submarine in the world. History In January 1850, Bauer, a cavalryman during the German-Danish War, designed ''Brandtaucher'' as a way to end the Danish naval blockade of Germany. Bauer's early sketch attracted the attention of the Minister of Marine, who allowed him to construct a model. The model was demonstrated in Kiel harbour in front of naval dignitaries. Its satisfactory performance led to the construction of a full-scale model, which was funded by contributions from army personnel and local civilians. Due to the inadequate funding, the scale of the boat had to be downgraded and the design altered and simplified; resulting in a reduced diving depth from 30 m to 9.5 m. This red ...

Submarine
A submarine (or sub) is a watercraft capable of independent operation underwater. It differs from a submersible, which has more limited underwater capability. The term is also sometimes used historically or colloquially to refer to remotely operated vehicles and robots, as well as medium-sized or smaller vessels, such as the midget submarine and the wet sub. Submarines are referred to as ''boats'' rather than ''ships'' irrespective of their size. Although experimental submarines had been built earlier, submarine design took off during the 19th century, and they were adopted by several navies. They were first widely used during World War I (1914–1918), and are now used in many navies, large and small. Military uses include attacking enemy surface ships (merchant and military) or other submarines, and for aircraft carrier protection, blockade running, nuclear deterrence, reconnaissance, conventional land attack (for example, using a cruise missile), and covert insertion o ...

Schleswig-Holstein
Schleswig-Holstein (; da, Slesvig-Holsten; nds, Sleswig-Holsteen; frr, Slaswik-Holstiinj) is the northernmost of the 16 states of Germany, comprising most of the historical duchy of Holstein and the southern part of the former Duchy of Schleswig. Its capital city is Kiel; other notable cities are Lübeck and Flensburg. The region is called ''Slesvig-Holsten'' in Danish and pronounced . The Low German name is ''Sleswig-Holsteen'', and the North Frisian name is ''Slaswik-Holstiinj''. In more dated English, it is also known as ''Sleswick-Holsatia''. Historically, the name can also refer to a larger region, containing both present-day Schleswig-Holstein and the former South Jutland County (Northern Schleswig; now part of the Region of Southern Denmark) in Denmark. It covers an area of , making it the 5th smallest German federal state by area (including the city-states). Schleswig was under Danish control during the Viking Age, but in the 12th century it escaped full co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gunboat
A gunboat is a naval watercraft designed for the express purpose of carrying one or more guns to bombard coastal targets, as opposed to those military craft designed for naval warfare, or for ferrying troops or supplies. History Pre-steam era In the age of sail, a gunboat was usually a small undecked vessel carrying a single smoothbore cannon in the bow, or just two or three such cannons. A gunboat could carry one or two masts or be oar-powered only, but the single-masted version of about length was most typical. Some types of gunboats carried two cannons, or else mounted a number of swivel guns on the railings. The small gunboat had advantages: if it only carried a single cannon, the boat could manoeuvre in shallow or restricted areas – such as rivers or lakes – where larger ships could sail only with difficulty. The gun that such boats carried could be quite heavy; a 32-pounder for instance. As such boats were cheap and quick to build, naval forces favoured s ...

Von Der Tann (gunboat)
''Von der Tann'' was a steam-powered 120 ton gunboat built in 1849 at Conradi shipyards in Kiel for the small joint navy of the two duchies of Schleswig and Holstein. She was the first propeller-driven gunboat in the world. History During the First War of Schleswig, 1848-1850 between Denmark and the two duchies, the Schleswig-Holstein navy comprised three paddlewheelers with sail rigging, a schooner and 12 gunboats; their task was to protect the coast against Danish raids. Initially called Gunboat No. 1, ''Von der Tann'' was the most modern of these ships. Her steam engine, built by August Howaldt at Schweffel und Howaldt's works in Kiel, gave her and a top speed (under steam) of six knots. She carried the rigging of a three-mast schooner, with a very tall funnel behind the main mast. Her armament comprised two 64-pounder guns mounted on swivels fore and aft plus four three-pounder howitzers. During the night of 20/21 July 1850, ''Von der Tann'' had captured a Danish f ...

Steam Engine
A steam engine is a heat engine that performs mechanical work using steam as its working fluid. The steam engine uses the force produced by steam pressure to push a piston back and forth inside a cylinder. This pushing force can be transformed, by a connecting rod and crank, into rotational force for work. The term "steam engine" is generally applied only to reciprocating engines as just described, not to the steam turbine. Steam engines are external combustion engines, where the working fluid is separated from the combustion products. The ideal thermodynamic cycle used to analyze this process is called the Rankine cycle. In general usage, the term ''steam engine'' can refer to either complete steam plants (including boilers etc.), such as railway steam locomotives and portable engines, or may refer to the piston or turbine machinery alone, as in the beam engine and stationary steam engine. Although steam-driven devices were known as early as the aeoli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
