Sewing Machines
A sewing machine is a machine used to sew fabric and materials together with Thread (yarn), thread. Sewing machines were invented during the first Industrial Revolution to decrease the amount of manual sewing work performed in clothing companies. Since the invention of the first sewing machine, generally considered to have been the work of Englishman Thomas Saint in 1790, the sewing machine has greatly improved the efficiency and productivity of the clothing industry. Home sewing machines are designed for one person to sew individual items while using a single Stitch (textile arts), stitch type at a time. In a modern sewing machine, the process of stitching has been automated so that the fabric easily glides in and out of the machine without the inconvenience of needles, Thimble, thimbles and other tools used in hand sewing. Early sewing machines were powered by either constantly turning a handle or with a foot-operated treadle mechanism. Electrically-powered machines were later i ...

Chain Stitch
Chain stitch is a sewing and embroidery technique in which a series of looped stitches form a chain-like pattern. Chain stitch is an ancient craft – examples of surviving Chinese chain stitch embroidery worked in silk thread have been dated to the Warring States period (5th – 3rd century BC). Handmade chain stitch embroidery does not require that the needle pass through more than one layer of fabric. For this reason the stitch is an effective surface embellishment near seams on finished fabric. Because chain stitches can form flowing, curved lines, they are used in many surface embroidery styles that mimic "drawing" in thread. Chain stitches are also used in making tambour lace, needlelace, macramé and crochet. In Azerbaijan, in the Sheki region, this ancient type of needlework is called tekeldus. History The earliest archaeological evidence of chain stitch embroidery dates from 1100 BC in China. Excavated from royal tombs, the embroidery was made using threads of silk. ...

Lockstitch
A lockstitch is the most common mechanical stitch made by a sewing machine. The term "single needle stitching", often found on dress shirt labels, refers to lockstitch. Structure The lockstitch uses two threads, an upper and a lower. Lockstitch is named because the two threads, upper and lower, "lock" (entwine) together in the hole in the fabric which they pass through. The upper thread runs from a spool kept on a spindle on top of or next to the machine, through a tension mechanism, through the take-up arm, and finally through the hole in the needle. Meanwhile, the lower thread is wound onto a bobbin, which is inserted into a case in the lower section of the machine below the material. To make one stitch, the machine lowers the threaded needle through the cloth into the bobbin area, where a rotating hook (or other hooking mechanism) catches the upper thread at the point just after it goes through the needle. The hook mechanism carries the upper thread entirely around th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Factory
A factory, manufacturing plant or a production plant is an industrial facility, often a complex consisting of several buildings filled with machinery, where workers manufacture items or operate machines which process each item into another. They are a critical part of modern economic production, with the majority of the world's goods being created or processed within factories. Factories arose with the introduction of machinery during the Industrial Revolution, when the capital and space requirements became too great for cottage industry or workshops. Early factories that contained small amounts of machinery, such as one or two spinning mules, and fewer than a dozen workers have been called "glorified workshops". Most modern factories have large warehouses or warehouse-like facilities that contain heavy equipment used for assembly line production. Large factories tend to be located with access to multiple modes of transportation, some having rail, highway and water loading ...

Patent
A patent is a type of intellectual property that gives its owner the legal right to exclude others from making, using, or selling an invention for a limited period of time in exchange for publishing an enabling disclosure of the invention."A patent is not the grant of a right to make or use or sell. It does not, directly or indirectly, imply any such right. It grants only the right to exclude others. The supposition that a right to make is created by the patent grant is obviously inconsistent with the established distinctions between generic and specific patents, and with the well-known fact that a very considerable portion of the patents granted are in a field covered by a former relatively generic or basic patent, are tributary to such earlier patent, and cannot be practiced unless by license thereunder." – ''Herman v. Youngstown Car Mfg. Co.'', 191 F. 579, 584–85, 112 CCA 185 (6th Cir. 1911) In most countries, patent rights fall under private law and the patent holder mus ...

Mining Engineer
Mining in the engineering discipline is the extraction of minerals from underneath, open pit, above or on the ground. Mining engineering is associated with many other disciplines, such as mineral processing, exploration, excavation, geology, and metallurgy, geotechnical engineering and surveying. A mining engineer may manage any phase of mining operations, from exploration and discovery of the mineral resources, through feasibility study, mine design, development of plans, production and operations to mine closure. With the process of Mineral extraction, some amount of waste and uneconomic material are generated which are the primary source of pollution in the vicinity of mines. Mining activities by their nature cause a disturbance of the natural environment in and around which the minerals are located. Mining engineers must therefore be concerned not only with the production and processing of mineral commodities, but also with the mitigation of damage to the environment both dur ...

Barthélemy Thimonnier
Barthélemy Thimonnier (19 August 1793 in L'Arbresle, Rhône - 5 July 1857 in Amplepuis) was a French inventor, who is attributed with the invention of the first sewing machine that replicated sewing by hand. He was born in L'Arbresle, in Rhône in France. Early life In 1795, his family moved to Amplepuis. Thimonnier was the eldest of seven children. He studied for a while in Lyon, before going to work as a tailor in Panissières. Barthelemy Thimonnier married an embroideress in January 1822. In 1823, he settled in a suburb of Saint-Étienne and worked as a tailor there. Invention of the sewing machine Though the first sewing machine needle was patented by Charles Fredrick Wiesenthal in 1755, in 1829 Thimonnier reinvented the sewing machine. In 1830 he signed a contract with Auguste Ferrand, a mining engineer, who made the requisite drawings and submitted a patent application. The patent for his machine was issued on 17 July 1830 in the names of both men, supported by the Fre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Josef Madersperger
Josef Madersperger (* October 6, 1768 in Kufstein; † October 2, 1850 in Vienna) was a tailor. He is one of the inventors of the sewing machine. Biography Josef Madersperger was born in 1768 in Kufstein. In 1790 his father and he relocated to Vienna because his parents' house in Tirol burned down. In 1807 he began development of the sewing machine, spending all his savings and leisure time. In 1814 he presented his first sewing machine, which imitated a human hand. Madersperger did not commercialize the 1815 granted privilege which expired after 3 years. By 1823 he was registered as a "former" middle-class tailor. After several unsuccessful attempts to improve the sewing machine, in 1839 he built a machine imitating the weaving process using the chain stitch. Madersperger was out of money, so he could not set up a factory. He donated the prototype to the Imperial–royal Polytechnical Institute (the predecessor of the TU Wien). In 1841 he received a bronze medal from the :de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sail
A sail is a tensile structure—which is made from fabric or other membrane materials—that uses wind power to propel sailing craft, including sailing ships, sailboats, windsurfers, ice boats, and even sail-powered land vehicles. Sails may be made from a combination of woven materials—including canvas or polyester cloth, laminated membranes or bonded filaments—usually in a three- or four-sided shape. A sail provides propulsive force via a combination of lift and drag, depending on its angle of attack—its angle with respect to the apparent wind. Apparent wind is the air velocity experienced on the moving craft and is the combined effect of the true wind velocity with the velocity of the sailing craft. Angle of attack is often constrained by the sailing craft's orientation to the wind or point of sail. On points of sail where it is possible to align the leading edge of the sail with the apparent wind, the sail may act as an airfoil, generating propulsive force as air p ...
