A Millennium technique and technology of production of bread remained virtually unchanged. Heavy manual labor of the bakers of Ancient Rome almost did not differ from toil bakers tsarist Russia in the twentieth century. And only in the twenties, when our country was created by the baking industry, to replace the ancient bakeries come highly mechanized enterprise. If the “Tsar’s Palace bread” in the Kremlin under Boris Godunov was baked the day 5 tons of bread and fed 5 thousand people, built in Soviet times, the bakery produces daily 300 – 500 tons of bread. Each factory and today provides bread to a million people.
Conveyer
Only 30 years ago, no one could tell what it is, not to mention what wonders he can create. Times have changed. And today it is difficult to imagine a modern home or office where there is at least one such revolutionary inventions.TOOTHPICKS
Someone impale them on sandwiches, someone makes them reduced copies of famous buildings, and some use them as intended, to remove stuck food between teeth. Welcome to the factory where they make modest zubachistca. Raw materials for toothpicks the most simple – logs, lots of logs, or rather of birch wood. The transformation of the Yule log begins with the separation of the bark, bark is not suitable for the manufacture of toothpicks, but it is not wasted, it is sold to a nearby factory where it is used as fuel. The log is processed on the machine twice, the result takes the form of a right cylinder, convenient for further processing. A special machine turns the log like a roll of paper simultaneously slitting thin layers dvenadtsaty sharp blades.
SHEET GLASS
Float glass is the basic product of the glass industry is a colorless , transparent, mirrored or tinted sodium-calcium-silicate glass manufactured by methods of float or vertical extraction without any additional surface treatment having the form of flat rectangular sheets whose thickness is small relative to the length and width. Typically use glass with a thickness of 1.9 to 19 mm.
BEER
A video about the process of creating beer.
Beer — low-alcohol beverage obtained by alcoholic fermentation of malt wort using beer yeast, often with the addition of hops. The ethanol content in most varieties of beer to 3-6 %. (and sometimes above, the strong usually contains about 8%., maximum — 14 %), dry matter (mostly carbohydrates) — 7-10 %, carbonic gas — 0,48-1,0 %.
NAILS AND STATIONERY BRACKETS
25 million pieces every day. Any handyman will tell you that a bad worker blames their tools, and the worst – blames nails. But now it’s no longer a justification since, as made nails for wood with a flat cap and a screw thread. Have you ever wondered how millions of these little pins are the same size?
FLUORESCENT LAMPS
Fluorescent lamp — gas discharge light source in which visible light is emitted mainly by the phosphor, which, in turn, glows under the ultraviolet radiation of the discharge; the discharge also emits visible light, but to a much lesser extent. Luminous efficacy of a fluorescent lamp is several times greater than incandescent lamps of similar power. The lifetime of fluorescent lamps can exceed 20 times the life of incandescent lamps while ensuring sufficient quality of power supply, ballast, and compliance with restrictions on the number of on / off.
ALUMINUM FOIL
Aluminum foil and materials on its basis are widely applied in packaging thanks to the unique protective and decorative properties.
Analyzing its functional properties, we can easily see that it has a number of very significant advantages compared to other packaging materials.
Proof. When the thickness of the foil 0.025 mm and higher it is almost impermeable to vapours and gases. Even with the thickness of 0.009 mm, the degree of water vapor transmittance is only 0.01 g/m2 per day, which can be considered more than acceptable.
CONTACT LENSES
Contact lenses small made from transparent materials lenses, worn directly on the eye for vision correction (i.e., to improve visual acuity).
Contact lenses, according to experts, are about 125 million people in the world. Method of vision correction using contact lenses is called contact vision correction.
Almost 50% of those who wear contact lenses, are young people aged 18 to 25 years. And among those who wear contact lenses for the first time, the proportion of young people under the age of 35 years, almost 90 %.
The story of the creation of contact lenses starts with the name of Leonardo da Vinci. In 1508, he designed the device in a transparent globe filled with water, through which people with poor eyesight can see better.
CDS
Since 1981, these disks began to advance and now it is not only a device for storing information for computers, and discs with your favorite music or your favorite movies.
And here is how to make these disks on an industrial scale and how they put it on these discs says this video.
CD-ROM (eng. Compact Disc) — optical storage medium in the form of a plastic disk with a hole in the center, the process of recording and reading of information is carried out with a laser. Further development of the CD-ROM became a DVD.
