Ivan Ivanovich Polzunov
Ivan Ivanovich Polzunov (russian: link=no, Иван Иванович Ползунов 1728 – May 27, 1766 n.s.) was a Russian inventor. He created the first steam engine in Russia and the first two-cylinder engine in the world. Minor planet 1978SP7 is named in his honor, as is a crater on the Moon. Biography Ivan Polzunov was born in the family of a soldier of peasant origin in the town Turinsk (currently Sverdlovsk Oblast region, Russia). After graduating in 1742 from ''Mining school'' (Горнозаводская Школа) in Ekaterinburg he worked as a ''mechanic's apprentice'' for the Chief Mechanic of Ural Plants ''Nikita Bakharev''. Beginning in 1748 he worked in Barnaul. In the library of Barnaul plant he found works of Mikhail Lomonosov, that he studied by himself as well as the descriptions of contemporary steam machines by ''I. Shlatter''. In 1763 he proposed an original 1.8 h.p. (1.2 kW) steam machine. The design used two cylinders on the same shaft that al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Horsepower
Horsepower (hp) is a unit of measurement of power, or the rate at which work is done, usually in reference to the output of engines or motors. There are many different standards and types of horsepower. Two common definitions used today are the mechanical horsepower (or imperial horsepower), which is about 745.7 watts, and the metric horsepower, which is approximately 735.5 watts. The term was adopted in the late 18th century by Scottish engineer James Watt to compare the output of steam engines with the power of draft horses. It was later expanded to include the output power of other types of piston engines, as well as turbines, electric motors and other machinery. The definition of the unit varied among geographical regions. Most countries now use the SI unit watt for measurement of power. With the implementation of the EU Directive 80/181/EEC on 1 January 2010, the use of horsepower in the EU is permitted only as a supplementary unit. History The development of the ...

Russkaya Starina
''Russkaya Starina'' ( rus, Русская старина, p=ˈruskəjə stərʲɪˈna; ''Russian Antiquity'') was a Russian history journal published monthly in St. Petersburg by amateur historian Mikhail Semevsky and his successors between 1870 and 1916. Its authors included Ivan Zabelin, Dmitry Ilovaysky, Nikolai Karlovich Shilder, and Nikolay Kostomarov. A collected edition was reprinted in 2008. Semevsky was highly enthusiastic about the history of 18th-century Russia. His journal covered the imperial period of Russian history, including the era of palace revolutions. It was ''Russkaya Starina'' that first brought to light the unpublished pages of ''Eugene Onegin'' and ''Dead Souls'', Bolotov's memoirs, Kuchelbecker's diary A diary is a written or audiovisual record with discrete entries arranged by date reporting on what has happened over the course of a day or other period.

Tuberculosis
Tuberculosis (TB) is an infectious disease usually caused by '' Mycobacterium tuberculosis'' (MTB) bacteria. Tuberculosis generally affects the lungs, but it can also affect other parts of the body. Most infections show no symptoms, in which case it is known as latent tuberculosis. Around 10% of latent infections progress to active disease which, if left untreated, kill about half of those affected. Typical symptoms of active TB are chronic cough with blood-containing mucus, fever, night sweats, and weight loss. It was historically referred to as consumption due to the weight loss associated with the disease. Infection of other organs can cause a wide range of symptoms. Tuberculosis is spread from one person to the next through the air when people who have active TB in their lungs cough, spit, speak, or sneeze. People with Latent TB do not spread the disease. Active infection occurs more often in people with HIV/AIDS and in those who smoke. Diagnosis of active ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blowing Engine
A blowing engine is a large stationary steam engine or internal combustion engine directly coupled to air pumping cylinders. They deliver a very large quantity of air at a pressure lower than an air compressor, but greater than a centrifugal fan. Blowing engines are majorly used to provide the air blast for furnaces, blast furnaces and other forms of smelter. Waterwheel engines The very first blowing engines were the blowing houses: bellows, driven by waterwheels. Smelters are most economically located near the source of their ore, which may not have suitable water power available nearby. There is also the risk of drought interrupting the water supply, or of expanding demand for the furnace outstripping the available water capacity. These restrictions led to the very earliest form of steam engine used for power generation rather than pumping, the water-returning engine. With this engine, a steam pump was used to raise water that in turn drove a waterwheel and thus the machin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Poruchik
The rank of lieutenant in Eastern Europe ( hr, poručnik, cs, poručík, pl, porucznik, russian: script=latn, poruchik, sr, script=latn, poručnik, sk, poručík) is one used in Slavophone armed forces. Depending on the country, it is either the lowest or second lowest officer rank. Etymology The rank designation might be derived from russian: поpученец (a person tasked by a special mission); russian: поручение (to receive an order) or russian: пору́чить (tasked to look after). Normally the received military orders in written form and was responsible to meet the particular goals and objectives anticipated. Russian imperial armed forces The Imperial Russian Army introduced this rank first in middle of the 17th century, by the Strelets so-called New Order Regiments , reflected in the Table of Ranks. A ''poruchik'' was normally assigned to assistant commanding officer of a company, later platoon. In 1798 this particular rank designation was ...

Drive Shaft
A drive shaft, driveshaft, driving shaft, tailshaft ( Australian English), propeller shaft (prop shaft), or Cardan shaft (after Girolamo Cardano) is a component for transmitting mechanical power and torque and rotation, usually used to connect other components of a drivetrain that cannot be connected directly because of distance or the need to allow for relative movement between them. As torque carriers, drive shafts are subject to torsion and shear stress, equivalent to the difference between the input torque and the load. They must therefore be strong enough to bear the stress, while avoiding too much additional weight as that would in turn increase their inertia. To allow for variations in the alignment and distance between the driving and driven components, drive shafts frequently incorporate one or more universal joints, jaw couplings, or rag joints, and sometimes a splined joint or prismatic joint. History The term ''driveshaft'' first appeared during the mid-1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

New Style
Old Style (O.S.) and New Style (N.S.) indicate dating systems before and after a calendar change, respectively. Usually, this is the change from the Julian calendar to the Gregorian calendar as enacted in various European countries between 1582 and 1923. In England, Wales, Ireland and Britain's American colonies, there were two calendar changes, both in 1752. The first adjusted the start of a new year from Lady Day (25 March) to 1 January (which Scotland had done from 1600), while the second discarded the Julian calendar in favour of the Gregorian calendar, removing 11 days from the September 1752 calendar to do so.Spathaky, MikOld Style and New Style Dates and the change to the Gregorian Calendar "Before 1752, parish registers, in addition to a new year heading after 24th March showing, for example '1733', had another heading at the end of the following December indicating '1733/4'.
