Public Company
A public company is a company whose ownership is organized via shares of share capital, stock which are intended to be freely traded on a stock exchange or in over-the-counter (finance), over-the-counter markets. A public (publicly traded) company can be listed on a stock exchange (listing (finance), listed company), which facilitates the trade of shares, or not (unlisted public company). In some jurisdictions, public companies over a certain size must be listed on an exchange. In most cases, public companies are ''private'' enterprises in the ''private'' sector, and "public" emphasizes their reporting and trading on the public markets. Public companies are formed within the legal systems of particular states and so have associations and formal designations, which are distinct and separate in the polity in which they reside. In the United States, for example, a public company is usually a type of corporation, though a corporation need not be a public company. In the United Kin ...

Aktiengesellschaft
(; abbreviated AG ) is a German language, German word for a corporation limited by Share (finance), share ownership (i.e., one which is owned by its shareholders) whose shares may be traded on a stock market. The term is used in Germany, Austria, Switzerland (where it is equivalent to a ''S.A. (corporation), société anonyme'' or a ''società per azioni'') and South Tyrol for companies incorporated there. In the United Kingdom, the equivalent term is public limited company, and in the United States, while the terms "Incorporation (business), incorporated" or "corporation" are typically used, technically the more precise equivalent term is "joint-stock company". Meaning of the word The German word ''Aktiengesellschaft'' is a compound noun made up of two elements: ''Aktien'' meaning an acting part or shares, share, and ''Gesellschaft'', meaning company or society. English translations include ''share company'', or ''company limited by shares'', or joint-stock company. In German, ...

Air Brake (road Vehicle)
An air brake or, more formally, a compressed-air-brake system, is a type of friction brake for vehicles in which compressed air pressing on a piston is used to both release the parking/emergency brakes in order to move the vehicle, and also to apply pressure to the brake pads or brake shoes to slow and stop the vehicle. Air brakes are used in large heavy vehicles, particularly those having multiple trailers which must be linked into the brake system, such as trucks, buses, trailers, and semi-trailers, in addition to their use in railroad trains. George Westinghouse first developed air brakes for use in railway service. He patented a safer air brake on March 5, 1872. Westinghouse made numerous alterations to improve his air pressured brake invention, which led to various forms of the automatic brake. In the early 20th century, after its advantages were proven in railway use, it was adopted by manufacturers of trucks and heavy road vehicles. Design and function Air br ...

Patent
A patent is a type of intellectual property that gives its owner the legal right to exclude others from making, using, or selling an invention for a limited period of time in exchange for publishing an sufficiency of disclosure, enabling disclosure of the invention."A patent is not the grant of a right to make or use or sell. It does not, directly or indirectly, imply any such right. It grants only the right to exclude others. The supposition that a right to make is created by the patent grant is obviously inconsistent with the established distinctions between generic and specific patents, and with the well-known fact that a very considerable portion of the patents granted are in a field covered by a former relatively generic or basic patent, are tributary to such earlier patent, and cannot be practiced unless by license thereunder." – ''Herman v. Youngstown Car Mfg. Co.'', 191 F. 579, 584–85, 112 CCA 185 (6th Cir. 1911) In most countries, patent rights fall under private la ...

Berlin Ringbahn
The Ringbahn (German for circle railway) is a long circle route around Berlin's inner city area, on the Berlin S-Bahn network. Its course is made up of a pair of tracks used by S-Bahn trains and another parallel pair of tracks used by various regional, long distance and freight trains. The S-Bahn lines S41 and S42 provide a closed-loop continuous service without termini. Lines S45, S46 and S47 use a section of the southern and western ring, while lines S8 and S85 use sections of the eastern ring. The combined number of passengers is about 400,000 passengers a day. Due to its distinctive shape, the line is often referred to as the ''Hundekopf'' (Dog's Head). The Ringbahn is bisected by an east–west railway thoroughfare called the Stadtbahn (city railway), which crosses the Ringbahn from Westkreuz (Western Cross) to Ostkreuz (Eastern Cross), forming a Südring (Southern Ring) and a Nordring (Northern Ring). The north-south S-Bahn link (with the North-South S-Bahn-tunnel as ...

Messerschmitt
Messerschmitt AG () was a German share-ownership limited, aircraft manufacturing corporation named after its chief designer Willy Messerschmitt from mid-July 1938 onwards, and known primarily for its World War II fighter aircraft, in particular the Bf 109 and Me 262. The company survived in the post-war era, undergoing a number of mergers and changing its name from Messerschmitt to Messerschmitt-Bölkow-Blohm before being bought by Deutsche Aerospace (DASA, now part of Airbus) in 1989. History Background In February 1916, the south German engineering company MAN AG and several banks purchased the unprofitable aircraft builder Otto-Flugzeugwerke, starting a new company, ''Bayerische Flugzeugwerke AG'' (abbreviated ''B.F.W.'', and meaning approximately "Bavarian Aircraft Factory"). The articles of association were drawn up on 19 and 20 February, and completed on 2 March 1916. Details of the company were recorded in the Commercial Register with an equity capital of RM  ...

History Of BMW
The official founding date of the German motor vehicle manufacturer BMW is 7 March 1916, when an aircraft producer called ''Bayerische Flugzeugwerke'' (formerly '' Otto Flugmaschinenfabrik'') was established. This company was renamed to ''Bayerische Motoren Werke'' (BMW) in 1922. However, the BMW name dates back to 1917, when ''Rapp Motorenwerke'' changed its name to ''Bayerische Motoren Werke''. BMW's first product was a straight-six aircraft engine called the BMW IIIa. Following the end of World War I, BMW remained in business by producing motorcycle engines, farm equipment, household items and railway brakes. This was not enough and the company was suspended, effectively bankrupt, from 6 November 1918 to 1 February 1919. BMW turned to motorcycle engine manufacturing, building a smooth operating horizontally opposed engine to keep the centre of mass low and thus make a more responsive machine. The engine was well received but the motorcycles made using it were not and sold ...

Camillo Castiglioni
Camillo Castiglioni (22 October 1879 – 18 December 1957) was an Italian-Austrian Jewish financier and banker, and was the wealthiest man in Central Europe during World War I. Nicknamed "Austrian Stinnes", he was active in aviation's pioneering days and invested in the arts. Castiglioni was credited as being instrumental to the founding of what would eventually become BMW AG. Early life Castiglioni was born in Trieste, then part of Austria-Hungary, to the chief rabbi. His older brother was Arturo Castiglioni. It is not known when Camillo developed his interest in aviation, but it is known that he was passionate about flying. Camillo's education was primarily law, gaining employment as an attorney and legal officer of a bank in Padua, quickly learning international finance and how to manage capital. He was the son of a rubber maker, so naturally Camillo found work with the Austro-American ''Gummiwarenfabrik AG'' (rubber products) in Vienna as an agent for the Kaufmann automobile ...

Bavarian Group Administration
{{unreferenced, date=October 2024 The Bavarian Group Administration or ''Gruppenverwaltung Bayern'' was a largely autonomous railway administration within the Deutsche Reichsbahn (German Imperial Railways) between the two world wars. It was formed on 1 April 1920 from the former Bavarian State Railways, and was unique, Bavaria being the only former German state to have such status after the merger of the seven state railway companies into the Reichsbahn. The rest of Germany was simply divided into various regional Reichsbahn railway divisions. The Bavarian Group Administration itself also had four railway divisions: Augsburg, Munich, Nuremberg and Regensburg which reported to it and not, as in the rest of Germany, to the Reichsbahn directly. The former Palatinate Railway formed the Ludwigshafen division. On 1 October 1933, as the only group administration within the Deutsche Reichsbahn, the ''Gruppenverwaltung Bayern'', was disbanded. Between 1920 and about 1924 when the Deutsche ...

Air Brake (rail)
A railway air brake is a railway brake power braking system with compressed air as the operating medium. Modern trains rely upon a fail-safe air brake system that is based upon a design patented by George Westinghouse on April 13, 1869. The Westinghouse Air Brake Company was subsequently organized to manufacture and sell Westinghouse's invention. In various forms, it has been nearly universally adopted. The Westinghouse system uses air pressure to charge air reservoirs (tanks) on each car. Full air pressure causes each car to release the brakes. A subsequent reduction or loss of air pressure causes each car to apply its brakes, using the compressed air stored in its reservoirs. Overview Straight air brake In the air brake's simplest form, referred to as a ''straight air system'', compressed air is directed to a pneumatic cylinder, ''brake cylinder'', causing its piston to apply force to mechanical linkage, which linkage is conventionally referred to as the brake_rigging#Br ...
