Peter Von Rittinger
Peter Ritter von Rittinger or Peter von Rittinger (see styling variants at ''Ritter'') (23 January 1811 Nový Jičín / Neutitschein – 7 December 1872 Vienna) was an Austrian pioneer of mineral processing. Life After completion of legal studies, von Rittinger studied in the mining department at the Mining and Forestry Academy in Schemnitz (Banská Štiavnica, Slovakia). After completing his studies in 1840, he immediately became a stamp mill inspector in the civil service. In this role, he led a number of improvements in mineral processing. In 1849, he was appointed the head of the Office to the Jáchymov district. That year also witnessed the invention of the continuous transverse shock outbreak. The introduction of this innovation in processing technology constituted a major advance. Continuous operation was made possible by the surge range. This separation process was based on differing specific gravities of minerals in the slurry, which in Rittinger's structure, along wit ...

Nový Jičín
Nový Jičín (; german: Neutitschein) is a town in the Moravian-Silesian Region of the Czech Republic. It has about 23,000 inhabitants. The historic centre of Nový Jičín is well preserved and is protected by law as an urban monument reservation. Nový Jičín is known for the hatting industry and is nicknamed the "town of hats". Administrative parts Villages of Bludovice, Kojetín, Loučka, Straník and Žilina are administrative parts of Nový Jičín. Etymology There are two theories as to how the name "Jičín" came about. According to local legends, it could be derived from the brave daughter of a local castle owner named Jitka (''Jitčín'', later amended to Jičín). Another theory derives the name from the Slavic word for wild boar ''div'' (''Dičín'', later amended to Jičín). The attribute ''Nový'' ("new") was added to distinguish it from Starý Jičín ("Old Jičín"). Geography Nový Jičín is situated about southwest of Ostrava. It is located in the Moravi ...

Heat Pump
A heat pump is a device that can heat a building (or part of a building) by transferring thermal energy from the outside using a refrigeration cycle. Many heat pumps can also operate in the opposite direction, cooling the building by removing heat from the enclosed space and rejecting it outside. Units that only provide cooling are called air conditioners. When in heating mode, a refrigerant at outside temperature is being compressed. As a result, the refrigerant becomes hot. This thermal energy can be transferred to an indoor unit. After being moved outdoors again, the refrigerant is decompressed — evaporated. It has lost some of its thermal energy and returns colder than the environment. It can now take up the surrounding energy from the air or from the ground before the process repeats. Compressors, fans, and pumps run with electric energy. Common types are air-source heat pumps, ground-source heat pumps, water-source heat pumps and exhaust air heat pumps. They are al ...

Ritter
Ritter (German for "knight") is a designation used as a title of nobility in German-speaking areas. Traditionally it denotes the second-lowest rank within the nobility, standing above "Edler" and below "Freiherr" (Baron). As with most titles and designations within the nobility in German-speaking areas, the rank was hereditary and generally was used with the nobiliary particle of von or zu before a family name. For its historical association with warfare and the landed gentry in the Middle Ages, the title of Ritter can be considered roughly equal to the titles of "Knight", but it is hereditary like the British title of "Baronet". The wife of a Ritter was called a "Frau" (in this sense "Lady") and not Ritterin. In heraldry, from the late 18th century a Ritter was often indicated by the use of a coronet with five points, although not everyone who was a Ritter and displayed arms made use of such a coronet. In the Austrian Empire and Austria-Hungary the title of "Ritter von" was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Banská Štiavnica
Banská Štiavnica (; german: Schemnitz; hu, Selmecbánya (Selmec), ) is a town in central Slovakia, in the middle of an immense caldera created by the collapse of an ancient volcano. For its size, the caldera is known as the Štiavnica Mountains. Banská Štiavnica has a population of more than 10,000. It is a completely preserved medieval town. Because of their historical value, the town and its surroundings were proclaimed by the UNESCO to be a World Heritage Site on December 11, 1993. History The fate of Banská Štiavnica has been closely linked to the exploitation of its abundant resources of silver ore. According to evidence from excavations, the site was settled during the Neolithic period. The first mining settlement was founded by Celts in the 3rd century BC. It was probably occupied by the Celtic Cotini tribe. Roman authors mentioned mining activities of the Cotini, who had lived in present-day central Slovakia until they were deported to Pannonia within the Marcomann ...

Jáchymov
Jáchymov (); german: Sankt Joachimsthal or ''Joachimsthal'') is a spa town in Karlovy Vary District in the Karlovy Vary Region of the Czech Republic. It has about 2,300 inhabitants. The historical core of the town from the 16th century is well preserved and protected by law as urban monument zone. It is a comprehensive set of Gothic–Renaissance patrician houses. Jáchymov has a long mining tradition, thanks to which it used to be the second most populous town in the Kingdom of Bohemia in 1534. At first silver was mined here. The silver coins minted here since the 16th century gave their name to the Thaler and the dollar. After the Wieliczka Salt Mine ceased industrial exploitation in 2007, the Svornost mine (1525) became the oldest mine still in use in Europe. It is also the first and for a long time the only mine in the world, where radium was mined. The mining cultural landscape of Jáchymov is a UNESCO World Heritage Site as a part of the Ore Mountain Mining Region. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Applied Science
Applied science is the use of the scientific method and knowledge obtained via conclusions from the method to attain practical goals. It includes a broad range of disciplines such as engineering and medicine. Applied science is often contrasted with basic science, which is focused on advancing scientific theories and laws that explain and predict events in the natural world. Applied science can also apply formal science, such as statistics and probability theory, as in epidemiology. Genetic epidemiology is an applied science applying both biological and statistical methods. Applied research Applied research is the practical application of science. It accesses and uses accumulated theories, knowledge, methods, and techniques, for a specific state-, business-, or client-driven purpose. Applied Research can be better understood in any area when contrasting it with, basic, or pure, research. Basic geography research strives to create new theories and methods that aid in the expl ...

Comminution
Comminution is the reduction of solid materials from one average particle size to a smaller average particle size, by crushing, grinding, cutting, vibrating, or other processes. In geology, it occurs naturally during faulting in the upper part of the Earth's crust. In industry, it is an important unit operation in mineral processing, ceramics, electronics, and other fields, accomplished with many types of mill. In dentistry, it is the result of mastication of food. In general medicine, it is one of the most traumatic forms of bone fracture. Within industrial uses, the purpose of comminution is to reduce the size and to increase the surface area of solids. It is also used to free useful materials from matrix materials in which they are embedded, and to concentrate minerals. Energy requirements The comminution of solid materials consumes energy, which is being used to break up the solid into smaller pieces. The comminution energy can be estimated by: * Rittinger's law, which assu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Work (physics)
In physics, work is the energy transferred to or from an object via the application of force along a displacement. In its simplest form, for a constant force aligned with the direction of motion, the work equals the product of the force strength and the distance traveled. A force is said to do ''positive work'' if when applied it has a component in the direction of the displacement of the point of application. A force does ''negative work'' if it has a component opposite to the direction of the displacement at the point of application of the force. For example, when a ball is held above the ground and then dropped, the work done by the gravitational force on the ball as it falls is positive, and is equal to the weight of the ball (a force) multiplied by the distance to the ground (a displacement). If the ball is thrown upwards, the work done by its weight is negative, and is equal to the weight multiplied by the displacement in the upwards direction. When the force is consta ...

Power (physics)
In physics, power is the amount of energy transferred or converted per unit time. In the International System of Units, the unit of power is the watt, equal to one joule per second. In older works, power is sometimes called ''activity''. Power is a scalar quantity. Power is related to other quantities; for example, the power involved in moving a ground vehicle is the product of the aerodynamic drag plus traction force on the wheels, and the velocity of the vehicle. The output power of a motor is the product of the torque that the motor generates and the angular velocity of its output shaft. Likewise, the power dissipated in an electrical element of a circuit is the product of the current flowing through the element and of the voltage across the element. Definition Power is the rate with respect to time at which work is done; it is the time derivative of work: P =\frac where is power, is work, and is time. If a constant force F is applied throughout a distance x, the wor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
