Carl August Klindworth
Ludwig Carl August Klindworth was a nineteenth-century German mechanic and entrepreneur. He was an instructor of the later manufacturer, civil director and senator Conrad Bube. He was honoured in 1837 by the trade association of the Kingdom of Hanover with the Golden Needle Award "for his machines to weaving and spinning mills", including the mechanical weaving machine. Family Klindworth was born on 5 June 1791 in Göttingen as the second son of the Göttinger mechanic and clockmaker Johann Andreas Klindworth (1742–1813) and Friederica Eleonora Klindworth, née Diedrich. His elder brother was Karl Friedrich Felix Klindworth (c. 1788-1851), who took over his father's business at the same time to ensure the oppressive obligation for the upkeeping of his mother and siblings, and his younger brother was politician and State Council Georg Klindworth. In 1785 Carl Augustus married Dorothea Wilhelmine (1800–1853), née Lamminger, the daughter of court printer Johann Thomas Lamminger ( ...

Rolling Mills
In metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness, to make the thickness uniform, and/or to impart a desired mechanical property. The concept is similar to the rolling of dough. Rolling is classified according to the temperature of the metal rolled. If the temperature of the metal is above its recrystallization temperature, then the process is known as hot rolling. If the temperature of the metal is below its recrystallization temperature, the process is known as cold rolling. In terms of usage, hot rolling processes more tonnage than any other manufacturing process, and cold rolling processes the most tonnage out of all cold working processes... Roll stands holding pairs of rolls are grouped together into rolling mills that can quickly process metal, typically steel, into products such as structural steel (I-beams, angle stock, channel stock), bar stock, and rails. Most steel mills ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1862 Deaths
Year 186 ( CLXXXVI) was a common year starting on Saturday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Aurelius and Glabrio (or, less frequently, year 939 ''Ab urbe condita''). The denomination 186 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Waldemar R
Waldemar, Valdemar or Woldemar is an Old High German given name. It consists of the elements ''wald-'' "power", "brightness" and ''-mar'' "fame". The name is considered the equivalent of the Slavic name Vladimir, Volodymyr, Uladzimir or Włodzimierz. The Old Norse form ''Valdamarr'' (also ''Valdarr'') occurs in the Guðrúnarkviða II as the name of a king of the Danes. The Old Norse form is also used in Heimskringla, in the story of Harald Hardrada, as the name of a ruler of Holmgard (Veliky Novgorod), in this case as a translation of the Slavic name ''Volodimer''.Alison Finlay (2004). ''Fagrskinna: A Catalogue of the Kings of Norway''. Brillp. 236 The ''Fagrskinna'' kings' sagas also have ''Valdamarr'' as the translation of Slavic ''Volodimer''/''Vladimir'', in reference to both Vladimir the Great and Vladimir Yaroslavovich. The German form was introduced to Scandinavia as ''Valdemar'' in the 12th century, with king Valdemar I of Denmark. People with the name Royalty * V ...

Thermometers
A thermometer is a device that measures temperature or a temperature gradient (the degree of hotness or coldness of an object). A thermometer has two important elements: (1) a temperature sensor (e.g. the bulb of a mercury-in-glass thermometer or the pyrometric sensor in an infrared thermometer) in which some change occurs with a change in temperature; and (2) some means of converting this change into a numerical value (e.g. the visible scale that is marked on a mercury-in-glass thermometer or the digital readout on an infrared model). Thermometers are widely used in technology and industry to monitor processes, in meteorology, in medicine, and in scientific research. History While an individual thermometer is able to measure degrees of hotness, the readings on two thermometers cannot be compared unless they conform to an agreed scale. Today there is an absolute thermodynamic temperature scale. Internationally agreed temperature scales are designed to approximate this close ...

Linear Scale
A linear scale, also called a bar scale, scale bar, graphic scale, or graphical scale, is a means of visually showing the scale of a map, nautical chart, engineering drawing, or architectural drawing. A scale bar is common element of map layouts. On large scale maps and charts, those covering a small area, and engineering and architectural drawings, the linear scale can be very simple, a line marked at intervals to show the distance on the earth or object which the distance on the scale represents. A person using the map can use a pair of dividers (or, less precisely, two fingers) to measure a distance by comparing it to the linear scale. The length of the line on the linear scale is equal to the distance represented on the earth multiplied by the map or chart's scale. In most projections, scale varies with latitude, so on small scale maps, covering large areas and a wide range of latitudes, the linear scale must show the scale for the range of latitudes covered by the map. ...

Barometers
A barometer is a scientific instrument that is used to measure air pressure in a certain environment. Pressure tendency can forecast short term changes in the weather. Many measurements of air pressure are used within surface weather analysis to help find surface troughs, pressure systems and frontal boundaries. Barometers and pressure altimeters (the most basic and common type of altimeter) are essentially the same instrument, but used for different purposes. An altimeter is intended to be used at different levels matching the corresponding atmospheric pressure to the altitude, while a barometer is kept at the same level and measures subtle pressure changes caused by weather and elements of weather. The average atmospheric pressure on the earth's surface varies between 940 and 1040 hPa (mbar). The average atmospheric pressure at sea level is 1013 hPa (mbar). Etymology The word ''barometer'' is derived from the Ancient Greek (), meaning "weight", and (), meaning "measure ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Binoculars
Binoculars or field glasses are two refracting telescopes mounted side-by-side and aligned to point in the same direction, allowing the viewer to use both eyes (binocular vision) when viewing distant objects. Most binoculars are sized to be held using both hands, although sizes vary widely from opera glasses to large pedestal-mounted military models. Unlike a (monocular) telescope, binoculars give users a three-dimensional image: each eyepiece presents a slightly different image to each of the viewer's eyes and the parallax allows the visual cortex to generate an impression of depth. Optical designs Galilean Almost from the invention of the telescope in the 17th century the advantages of mounting two of them side by side for binocular vision seems to have been explored. Most early binoculars used Galilean optics; that is, they used a convex objective and a concave eyepiece lens. The Galilean design has the advantage of presenting an erect image but has a narrow field of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lorgnettes
A lorgnette () is a pair of spectacles with a handle, used to hold them in place, rather than fitting over the ears or nose. The word ''lorgnette'' is derived from the French ''lorgner'', to take a sidelong look at, and Middle French, from ''lorgne'', squinting. Their precise origin is debated: some sources describe English scientist George Adams the elder as their inventor, while others cite his son George Adams the younger. The lorgnette was usually used as a piece of jewelry, rather than to enhance vision. Fashionable ladies usually preferred them to spectacles. These were very popular at masquerade parties and used often at the opera. They were worn popularly in the 19th century. The lorgnette was employed as a prop and affectation by early 20th century trial lawyer Earl Rogers, and one is featured on the front cover dust jacket of his biography, ''Final Verdict'', by his daughter Adela Rogers St. Johns. Etymology This word comes from French ''lorgnette'', from ''lorgn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spectacles
Glasses, also known as eyeglasses or spectacles, are vision eyewear, with lenses (clear or tinted) mounted in a frame that holds them in front of a person's eyes, typically utilizing a bridge over the nose and hinged arms (known as temples or temple pieces) that rest over the ears. Glasses are typically used for vision correction, such as with reading glasses and glasses used for nearsightedness; however, without the specialized lenses, they are sometimes used for cosmetic purposes. Safety glasses provide eye protection against flying debris for construction workers or lab technicians; these glasses may have protection for the sides of the eyes as well as in the lenses. Some types of safety glasses are used to protect against visible and near-visible light or radiation. Glasses are worn for eye protection in some sports, such as squash. Glasses wearers may use a strap to prevent the glasses from falling off. Wearers of glasses that are used only part of the time may hav ...
