Kettle Drum
Timpani (; ) or kettledrums (also informally called timps) are musical instruments in the percussion family. A type of drum categorised as a hemispherical drum, they consist of a membrane called a head stretched over a large bowl traditionally made of copper. Thus timpani are an example of kettle drums, also known as vessel drums and semispherical drums, whose body is similar to a section of a sphere whose cut conforms the head. Most modern timpani are ''pedal timpani'' and can be tuned quickly and accurately to specific pitches by skilled players through the use of a movable foot-pedal. They are played by striking the head with a specialized drum stick called a ''timpani stick'' or ''timpani mallet''. Timpani evolved from military drums to become a staple of the classical orchestra by the last third of the 18th century. Today, they are used in many types of ensembles, including concert bands, marching bands, orchestras, and even in some rock bands. ''Timpani'' is an Italian ...

Hammer Mills Of Germany
A hammer is a tool, most often a hand tool, consisting of a weighted "head" fixed to a long handle that is swung to deliver an impact to a small area of an object. This can be, for example, to drive nails into wood, to shape metal (as with a forge), or to crush rock. Hammers are used for a wide range of driving, shaping, breaking and non-destructive striking applications. Traditional disciplines include carpentry, blacksmithing, warfare, and percussive musicianship (as with a gong). Hammering is use of a hammer in its strike capacity, as opposed to prying with a secondary claw or grappling with a secondary hook. Carpentry and blacksmithing hammers are generally wielded from a stationary stance against a stationary target as gripped and propelled with one arm, in a lengthy downward planar arc—downward to add kinetic energy to the impact—pivoting mainly around the shoulder and elbow, with a small but brisk wrist rotation shortly before impact; for extreme impact, conc ...

Eberhard Wächtler (10 May 1929 – 22 September 2010) was a Germans, German Economic history, economic historian. He was particularly notable for research in coal and steel sciences in postwar Germany. Wächtler was born in Dresden, Weimar Republic, in 1929. After graduating from high school in 1947, he studied history, literature, philosophy and political economy at the University of Leipzig. In 1953 he graduated with a degree in history. He first worked as a research assistant in Leipzig, after which he worked as a research associate at the Institute of History of the German Academy of Sciences at Berlin until 1962. He received his doctorate in 1957 on the subject of the history of the condition miners in the coal district of Saxony-Lugau Ölsnitz from 1889-1914. He completed his habilitation in 1968 at the University of Rostock, with work on historical traditions in the German mining industry from 1807 to 1871.

Works Of Art
A work of art, artwork, art piece, piece of art or art object is an artistic creation of aesthetic value. Except for "work of art", which may be used of any work regarded as art in its widest sense, including works from literature and music, these terms apply principally to tangible, physical forms of visual art: *An example of fine art, such as a painting or sculpture. *Objects in the decorative arts or applied arts that have been designed for aesthetic appeal, as well as any functional purpose, such as a piece of jewellery, many ceramics and much folk art. *An object created for principally or entirely functional, religious or other non-aesthetic reasons which has come to be appreciated as art (often later, or by cultural outsiders). *A non-ephemeral photograph or film. *A work of installation art or conceptual art. Used more broadly, the term is less commonly applied to: *A fine work of architecture or landscape design *A production of live performance, such as ...

Metalsmith
A metalsmith or simply smith is a craftsperson fashioning useful items (for example, tools, kitchenware, tableware, jewelry, armor and weapons) out of various metals. Smithing is one of the oldest list of metalworking occupations, metalworking occupations. Shaping metal with a hammer (forging) is the archetypical component of smithing. Often the hammering is done while the metal is hot, having been heated in a forge. Smithing can also involve the other aspects of metalworking, such as refining metals from their ores (traditionally done by smelting), casting it into shapes (foundry, founding), and file (tool), filing to shape and size. The prevalence of metalworking in the culture of recent centuries has led ''Smith (surname), Smith'' and its equivalents in various languages to be a common surname#Occupational name, occupational surname (German Schmidt (surname), Schmidt or Schmied, Portuguese Ferreiro, Ferreira (surname), Ferreira, French Lefèvre, Spanish Herrero, Italian Fabbr ...

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 aeolipile in the f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metallurgical Furnace
A metallurgical furnace, more commonly referred to as a furnace, is a device used to heat and melt metal ore to remove gangue, primarily in Metal, iron and steel production. The heat energy to fuel a furnace may be supplied directly by fuel combustion, by electricity such as the electric arc furnace, or through induction heating in induction furnaces. There are several different types of furnaces used in metallurgy to work with specific metal and ores. Smelting furnaces Smelting furnaces are used in smelting to extract metal from ore. Smelting furnaces include: * The blast furnace, used to Redox, reduce iron ore to pig iron ** Cold blast ** Hot blast * Steelmaking furnaces, including: ** Puddling furnace ** Reverberatory furnace ** ** Open hearth furnace ** Basic oxygen furnace ** Electric arc furnace ** Electric induction furnace Other furnaces * Furnaces used to remelt metal in Foundry, foundries. * Furnaces used to reheat and Heat treatment, heat treat metal for use in: ...

Stamp Mill
A stamp mill (or stamp battery or stamping mill) is a type of mill machine that crushes material by pounding rather than grinding, either for further processing or for extraction of metallic ores. Breaking material down is a type of unit operation. Description A stamp mill consists of a set of heavy steel (iron-shod wood in some cases) stamps, loosely held vertically in a frame, in which the stamps can slide up and down. They are lifted by cams on a horizontal rotating shaft. As the cam moves from under the stamp, the stamp falls onto the ore below, crushing the rock, and the lifting process is repeated at the next pass of the cam. Each one frame and stamp set is sometimes called a "battery" or, confusingly, a "stamp" and mills are sometimes categorised by how many stamps they have, i.e. a "10 stamp mill" has 10 sets. They usually are arranged linearly, but when a mill is enlarged, a new line of them may be constructed rather than extending the line. Abandoned mill sites (as ...
