Dmitry Ivanovich Mendcleyev

Dmitry Ivanovich Mendeleyev is а famous Russian chemist. Не is best known for his development of the periodic table of the properties of the chemical elements. This table displays that elements' properties are changed periodically when they are arranged according to atomic weight.

Mendeleyev was born in 1834 in Tobolsk, Siberia. Не studied chemistry at the University of St. Petersburg, and in 1859 he was sent to study at the University of Heidelberg. Mendeleyev returned to St. Petersburg and became Professor of Chemistry at the Technical Institute in 1863. Не became Professor of General Chemistry at the University of St. Petersburg in 1866. Mendeleyev was а well - known teacher, and, because there was по good textbook in chemistry at that time, he wrote the two-volume «Principles of Chemistry» which became а classic textbook in chemistry.

In this book Mendeleyev tried to classify the elements according to their chemical properties. In 1869 he published his first version of his periodic table of elements. In 1871 he published an improved version of the periodic table, in which he left gaps for elements that were not known at that time. His table and theories were proved later when three predicted elements: gallium, germanium, and scandium were discovered.

НЕ нашли? Не то? Что вы ищете?

Mendeleyev investigated the chemical theory of solution. Не found that the best proportion of alcohol and water in vodka is 40%. Не also investigated the thermal expansion of liquids and the nature of petroleum.

In 1893 he became director of the Bureau of Weights and Measures in St. Petersburg and held this position until his death in 1907.

FAMOUS PEOPLE OF SCIENCE АХD ENGINEERING

Sikorsky Igor Ivanovich was а well-known aircraft engineer and manufacturer.

Sikorsky was born in 1889 in Kiev, in the Ukraine, and got his education at the naval college in St. Petersburg, and later in Kiev and Paris. Не was the first to make experiments in helicopter design. In 1913 he designed, built, and flew the first successful aeroplane. Later he built military aircrafts for Russia and France.

In 1919 Sikorsky moved to the United States and later helped to organize an aircraft company that produced а series of multiengine flying boats for commercial service. Sikorsky became an American citizen in 1928. In the late 1930s he returned to developing helicopters and produced the first successful helicopter in the west. Helicopters designed by Sikorsky were used mostly by the US Army Air Forces during World War II. Не died in 1972 at the age of 83.

Tupolev Andrey Nikolayevich, famous aircraft designer, was born in! 888. Не graduated frот the Moscow Higher Technical School, where he designed the first Russian wind tunnel. Не helped to found the Central Aerohydrodynamics Institute in 1918 and later worked as the head of its design bureau. During, his career he directed the design of more than 100 military and commercial aircraft, including the TU-2 and TU-4 bombers used in the World War II. In 1955 he designed the TU-104, the first passenger jet airliner. His TU-144 supersonic jet liner began its commercial passenger flights in 1977.

“MACHINE-TOOLS”

Machine-tools are used to shape metals and other materials. The material to be shaped is called the workpiece. Most machine-tools are now electrically driven. Machine-tools with electrical drive are faster and тоге accurate than hand tools: they were an important element in the development of mass-production processes, as they allowed individual parts to be made in large numbers so as to be interchangeable.

All machine-tools have facilities for holding both the workpiece and the tool, and for accurately controlling the movement of the cutting tool relative to the workpiece. Most machining operations generate large amounts of heat, and use cooling fluids (usually а mixture of water and oils) for cooling and lubrication.

Machine-tools usually work materials mechanically but other machining methods have been developed lately. They include chemical machining, spark erosion to machine very hard materials to any shape by means о1 а continuous high-voltage spark (discharge) between an electrode and а workpiece. Other machining methods include drilling using ultrasound, and cutting by means of а laser beam. Numerical control of machine-tools and flexible manufacturing systems have made it possible for complete systems of machine-tools to be used flexibly for the manufacture of а range of products.

“METALS”

Metals are materials most widely used in industry because of their properties. The study of the production and properties of metals is known as metallurgy.

The separation between the atoms in metals is small, so most metals are dense. The atoms are arranged regularly and can slide over each other. That is why metals are malleable (can be deformed and bent without fracture) and ductile (can be drawn into wire). Metals vary greatly in their properties. For example, lead is soft and can be bent by hand, while iron can only be worked by hammering at red heat.

The regular arrangement of atoms in metals gives them а crystalline structure. Irregular crystals are called grains. The properties of metals depend on the size shape, orientation, and composition of these grains. In general, а metal with small grains will be harder and stronger than one with coarse grains.

Heat treatment such as quenching, tempering, or annealing controls the nature of the grains and their size in the metal. Small amounts of other metals (less than 1 per cent) are often added to а риге metal. This is called аlloying (легирование) and it changes the grain structure and properties of metals.

A11 metals can be formed by drawing, rolling, hammering and extrusion, but some require hot-working. Metals are subject to metal fatigue and to creep (the slow increase in length under stress) causing deformation and failure. Both effects are taken into account by engineers when desiring for example, airplanes, gas-turbines, and pressure vessels for high-temperature chemical рrосеssеs. Metals can be worked using machine-tools such а» lathe, milling machine, shaper and grinder.

The ways of working а metal depend on its properties. Many metals can be melted and cast in moulds, but special conditions are required for metals that react wity air.
