K. Rudzki I S-ka
K. Rudzki i S-ka (Konstanty Rudzki & Co. Ltd.) was a Polish engineering and machinery company. Founded in Warsaw in 1858 as an iron foundry by a shipbuilding magnate Andrzej Artur Zamoyski and led by Konstanty Rudzki, it soon expanded into machinery, steel and engineering. By the end of the 19th century the company, with its seat in Warsaw and a large factory in Mińsk Mazowiecki, had become one of the largest and most experienced bridge construction contractors in Central and Eastern Europe, with roughly 20% of bridges constructed in the Russian Empire bearing the logo of K. Rudzki. After World War I the company declined and ceased its machinery production arm, but continued on as an engineering and construction business. It was nationalised and liquidated after World War II. Throughout its existence the company was responsible for some of the most innovative bridge undertakings in the world, including the 1914 Poniatowski Bridge, the 1916 Khabarovsk Bridge (for decades the longe ...

Poniatowski Bridge
The Poniatowski Bridge ( pl, Most Poniatowskiego) is a bridge in Warsaw, Poland. Originally built between 1904 and 1914, it was damaged in each World War and rebuilt after each. It spans the Vistula River, connecting Warsaw's Powiśle and Praga districts. Its viaduct is an extension of Jerusalem Avenue, a principal Warsaw thoroughfare. History The 506 m long steel bridge, consisting of eight spans, was designed by Stefan Szyller. Its construction, begun in 1904, was carried out by the K. Rudzki i S-ka company and supervised by engineers Mieczysław Marszewski and Wacław Paszkowski. Kazimierz Ołdakowski was another engineer who worked on the bridge, before he took over the directorship of Fabryka Broni. Despite being viewed by many as an extravagance (opponents of its construction included the then mayor of Warsaw and the writer Bolesław Prus), it was opened on January 6, 1914, by the Russian Governor General, Georgi Skalon, as Warsaw's ''third'' bridge; hence it wa ...

Czerniaków Port
Czerniaków is a neighbourhood of the city of Warsaw, located within the borough of Mokotów, between the escarpment of the Vistula river and the river itself. Called ''Czerniakowo'' since the Middle Ages, it was then merely a small village located well to the south of the Warsaw's Old Town. In the 19th century the area became densely built-up and became populated mostly by factory workers and other lower classes of society, which gave birth to a specific local version of the Warsaw dialect. During the Warsaw Uprising The Warsaw Uprising ( pl, powstanie warszawskie; german: Warschauer Aufstand) was a major World War II operation by the Polish underground resistance to liberate Warsaw from German occupation. It occurred in the summer of 1944, and it was led ... the area was one of the last Polish strongholds. Neighbourhoods of Mokotów {{warsaw-geo-stub ...

Centennial Exposition
The Centennial International Exhibition of 1876, the first official World's Fair to be held in the United States, was held in Philadelphia, Pennsylvania, from May 10 to November 10, 1876, to celebrate the 100th anniversary of the signing of the Declaration of Independence in Philadelphia. Officially named the International Exhibition of Arts, Manufactures, and Products of the Soil and Mine, it was held in Fairmount Park along the Schuylkill River on fairgrounds designed by Herman J. Schwarzmann. Nearly 10 million visitors attended the exposition, and 37 countries participated in it. Precursor The Great Central Fair on Logan Square in Philadelphia, Pennsylvania, in 1864 (also known as the Great Sanitary Fair), was one of the many United States Sanitary Commission's Sanitary Fairs held during the Civil War. They provided a creative and communal means for ordinary citizens to promote the welfare of Union soldiers and dedicate themselves to the survival of the nation, and the ...

De Jure
In law and government, ''de jure'' ( ; , "by law") describes practices that are legally recognized, regardless of whether the practice exists in reality. In contrast, ("in fact") describes situations that exist in reality, even if not legally recognized. Examples Between 1805 and 1914, the ruling dynasty of Egypt were subject to the rulers of the Ottoman Empire, but acted as de facto independent rulers who maintained a polite fiction of Ottoman suzerainty. However, starting from around 1882, the rulers had only de jure rule over Egypt, as it had by then become a British puppet state. Thus, by Ottoman law, Egypt was de jure a province of the Ottoman Empire, but de facto was part of the British Empire. In U.S. law, particularly after ''Brown v. Board of Education'' (1954), the difference between de facto segregation (segregation that existed because of the voluntary associations and neighborhoods) and de jure segregation (segregation that existed because of local laws that ...

January Uprising
The January Uprising ( pl, powstanie styczniowe; lt, 1863 metų sukilimas; ua, Січневе повстання; russian: Польское восстание; ) was an insurrection principally in Russia's Kingdom of Poland that was aimed at the restoration of the Polish–Lithuanian Commonwealth. It began on 22 January 1863 and continued until the last insurgents were captured by the Russian forces in 1864. It was the longest-lasting insurgency in partitioned Poland. The conflict engaged all levels of society and arguably had profound repercussions on contemporary international relations and ultimately provoked a social and ideological paradigm shift in national events that went on to have a decisive influence on the subsequent development of Polish society. A confluence of factors rendered the uprising inevitable in early 1863. The Polish nobility and urban bourgeois circles longed for the semi-autonomous status they had enjoyed in Congress Poland before the previous insu ...

Brass
Brass is an alloy of copper (Cu) and zinc (Zn), in proportions which can be varied to achieve different mechanical, electrical, and chemical properties. It is a substitutional alloy: atoms of the two constituents may replace each other within the same crystal structure. Brass is similar to bronze, another copper alloy, that uses tin instead of zinc. Both bronze and brass may include small proportions of a range of other elements including arsenic (As), lead (Pb), phosphorus (P), aluminium (Al), manganese (Mn), and silicon (Si). Historically, the distinction between the two alloys has been less consistent and clear, and modern practice in museums and archaeology increasingly avoids both terms for historical objects in favor of the more general "copper alloy". Brass has long been a popular material for decoration due to its bright, gold-like appearance; being used for drawer pulls and doorknobs. It has also been widely used to make utensils because of its low melti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Copper
Copper is a chemical element with the symbol Cu (from la, cuprum) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a pinkish-orange color. Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such as sterling silver used in jewelry, cupronickel used to make marine hardware and coins, and constantan used in strain gauges and thermocouples for temperature measurement. Copper is one of the few metals that can occur in nature in a directly usable metallic form ( native metals). This led to very early human use in several regions, from circa 8000 BC. Thousands of years later, it was the first metal to be smelted from sulfide ores, circa 5000 BC; the first metal to be cast into a shape in a mold, c. 4000 BC; and the first metal to be purposely alloyed with another metal, tin, to create ...

Cast Iron
Cast iron is a class of iron– carbon alloys with a carbon content more than 2%. Its usefulness derives from its relatively low melting temperature. The alloy constituents affect its color when fractured: white cast iron has carbide impurities which allow cracks to pass straight through, grey cast iron has graphite flakes which deflect a passing crack and initiate countless new cracks as the material breaks, and ductile cast iron has spherical graphite "nodules" which stop the crack from further progressing. Carbon (C), ranging from 1.8 to 4 wt%, and silicon (Si), 1–3 wt%, are the main alloying elements of cast iron. Iron alloys with lower carbon content are known as steel. Cast iron tends to be brittle, except for malleable cast irons. With its relatively low melting point, good fluidity, castability, excellent machinability, resistance to deformation and wear resistance, cast irons have become an engineering material with a wide range of applications a ...

Coke (fuel)
Coke is a grey, hard, and porous coal-based fuel with a high carbon content and few impurities, made by heating coal or oil in the absence of air—a destructive distillation process. It is an important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges when air pollution is a concern. The unqualified term "coke" usually refers to the product derived from low-ash and low-sulphur bituminous coal by a process called coking. A similar product called petroleum coke, or pet coke, is obtained from crude oil in oil refineries. Coke may also be formed naturally by geologic processes.B. Kwiecińska and H. I. Petersen (2004): "Graphite, semi-graphite, natural coke, and natural char classification — ICCP system". ''International Journal of Coal Geology'', volume 57, issue 2, pages 99-116. History China Historical sources dating to the 4th century describe the production of coke in ancient China. The Chinese first used coke for heatin ...

Turnery
Woodturning is the craft of using a wood lathe with hand-held tools to cut a shape that is symmetrical around the axis of rotation. Like the potter's wheel, the wood lathe is a simple mechanism that can generate a variety of forms. The operator is known as a turner, and the skills needed to use the tools were traditionally known as turnery. In pre-industrial England, these skills were sufficiently difficult to be known as 'the misterie' of the turners guild. The skills to use the tools by hand, without a fixed point of contact with the wood, distinguish woodturning and the wood lathe from the machinist's lathe, or metal-working lathe. Items made on the lathe include tool handles, candlesticks, egg cups, knobs, lamps, rolling pins, cylindrical boxes, Christmas ornaments, bodkins, knitting needles, needle cases, thimbles, pens, chessmen, spinning tops; legs, spindles, and pegs for furniture; balusters and newel posts for architecture; baseball bats, hollow forms such as woodwin ...
