Such a line is installed in the foundry capacity of 50 tons FTIMS castings per month. From her station in the molding shop is worth two One unit of equipment: vibrating table for forming a pipeline backfilling sand in the shape of the receiver is connected to the grid for vysypki flasks of containers of spent sand. Consumption per 1 ton of suitable casting consists of four model-forming materials: quartz sand – 50 kg, antipenetration coverage – 25 kg, Styrofoam… (more…)
Over 20 years of teaching programming at school (and in the further education of children) began with learning the language Pascal. Despite the fact that it is quite cumbersome programming language, it is always positioned as language learning. In the early 90's Dutchman Guido van Rossum created great language Python (in Russian, Python or Python). And although it was not designed as a 'language school', but has some significant advantages over Pascal in the same teaching beginners to programming. To… (more…)
Until the end of the year there were five pounds namyto platinum in 1826 – 10 pounds. In 100 poods sands here contain from 18 to 25 spools (1 spool equals 4.25 g) of platinum – a real treasure! Following this discovery placer followed one another. A relatively small area in the XIX century there were 22 mine. Placers were so rich that riverhead Visim termed "Rublevik." The old men told: "In the hat bring sand, and then slide and… (more…)
Pyrotechnic compositions equip the following types of funds for military purposes: 1) Lighting equipment (bombs, artillery shells, aerial flares, etc.) used to illuminate the area at night conditions, 2) fotoosvetitelnye means (fotobomby, fotopatrony) used in aerial night: and for other purposes, and 3) tracer means making visible the trajectory of bullets and shells (and other mobile objects) and thereby facilitate sighting lo quickly moving targets, and 4) the means of infrared radiation, used for tracking the flight of missiles, and… (more…)
Poor packing leads to flattening the pipe Bends, so the sand to condense, obstukivaya tube from top to bottom. After filling with sand the other end of the pipe need to hammer a wooden stopper, in which must be perforated to release gases when heated. Sometimes the as a filler is used water that freezes in the pipe. For each tube, depending on its diameter and the material must be set the minimum allowable bend radius. The radius of curvature… (more…)
The next floor of the pyramid of civilization – the technological mode of production, which expresses the aggregate used in society technologies, principles and organizational forms of production, capital goods, as well as natural productive forces. In the early stages of formation epoch of human society, archeologists and historians differ on the basic materials from which tools were made (stone, bronze, iron). The main source of energy was the muscular power of man, then animals, dominated by simple cooperation of… (more…)

Induction crucible furnace designed for melting and overheating of steel and cast iron. Possible melting of nonferrous metals (bronze, brass, aluminum) and their alloys in a graphite crucible. It is used in foundries, steel factories, workshops precision casting and repair shops engineering plants to produce steel castings of high quality. Induction heating – heating bodies in an electromagnetic field due to the heat of the vortex electric currents flowing through the heated body and excited in him due to the… (more…)
