Jacquard Weaving
The Jacquard machine () is a device fitted to a loom that simplifies the process of manufacturing textiles with such complex patterns as brocade, damask and matelassé. The resulting ensemble of the loom and Jacquard machine is then called a Jacquard loom. The machine was patented by Joseph Marie Jacquard in 1804, based on earlier inventions by the Frenchmen Basile Bouchon (1725), Jean Baptiste Falcon (1728), and Jacques Vaucanson (1740). The machine was controlled by a "chain of cards"; a number of punched cards laced together into a continuous sequence. Multiple rows of holes were punched on each card, with one complete card corresponding to one row of the design. Both the Jacquard process and the necessary loom attachment are named after their inventor. This mechanism is probably one of the most important weaving innovations as Jacquard shedding made possible the automatic production of unlimited varieties of complex pattern weaving. The term "Jacquard" is not specific or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
A La Mémoire De J
A, or a, is the first Letter (alphabet), letter and the first vowel of the Latin alphabet, Latin alphabet, used in the English alphabet, modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is English alphabet#Letter names, ''a'' (pronounced ), plural English alphabet#Letter names, ''aes''. It is similar in shape to the Greek alphabet#History, Ancient Greek letter alpha, from which it derives. The Letter case, uppercase version consists of the two slanting sides of a triangle, crossed in the middle by a horizontal bar. The lowercase version can be written in two forms: the double-storey a and single-storey ɑ. The latter is commonly used in handwriting and fonts based on it, especially fonts intended to be read by children, and is also found in italic type. In English grammar, "English articles, a", and its variant "English articles#Indefinite article, an", are Article (grammar)#Indefinite article, indefinite arti ...

Charles Babbage
Charles Babbage (; 26 December 1791 – 18 October 1871) was an English polymath. A mathematician, philosopher, inventor and mechanical engineer, Babbage originated the concept of a digital programmable computer. Babbage is considered by some to be " father of the computer". Babbage is credited with inventing the first mechanical computer, the Difference Engine, that eventually led to more complex electronic designs, though all the essential ideas of modern computers are to be found in Babbage's Analytical Engine, programmed using a principle openly borrowed from the Jacquard loom. Babbage had a broad range of interests in addition to his work on computers covered in his book ''Economy of Manufactures and Machinery''. His varied work in other fields has led him to be described as "pre-eminent" among the many polymaths of his century. Babbage, who died before the complete successful engineering of many of his designs, including his Difference Engine and Analytical En ...

Computing
Computing is any goal-oriented activity requiring, benefiting from, or creating computing machinery. It includes the study and experimentation of algorithmic processes, and development of both hardware and software. Computing has scientific, engineering, mathematical, technological and social aspects. Major computing disciplines include computer engineering, computer science, cybersecurity, data science, information systems, information technology and software engineering. The term "computing" is also synonymous with counting and calculating. In earlier times, it was used in reference to the action performed by mechanical computing machines, and before that, to human computers. History The history of computing is longer than the history of computing hardware and includes the history of methods intended for pen and paper (or for chalk and slate) with or without the aid of tables. Computing is intimately tied to the representation of numbers, though mathematical ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pasteboard
Card stock, also called cover stock and pasteboard, is paper that is thicker and more durable than normal writing and printing paper, but thinner and more flexible than other forms of paperboard. Card stock is often used for business cards, postcards, playing cards, catalogue covers, scrapbooking, and other applications requiring more durability than regular paper gives. The surface usually is smooth; it may be textured, metallic, or glossy. When card stock is labeled cover stock, it often has a glossy coating on one or both sides (''C1S'' or ''C2S'', for "coated: one side" or "coated: two sides"); this is used especially in business cards and book covers. Measurements Most nations describe paper in terms of grammage—the weight in grams of one sheet of the paper measuring one square meter. Other people, especially in the United States, describe paper in terms of pound weight—the weight in pounds per ream (500 sheets) of the paper with a given area (based on historic ...

Vaucanson
Jacques de Vaucanson (; February 24, 1709 – November 21, 1782) was a French inventor and artist who built the first all-metal lathe which was very important to the Industrial Revolution. The lathe is known as the mother of machine tools, as it was the first machine tool that led to the invention of other machine tools. He was responsible for the creation of impressive and innovative automata. He also was the first person to design an automatic loom. Early life De Vaucanson was born in Grenoble, France in 1709 as Jacques Vaucanson (the nobiliary particle "de" was later added to his name by the Académie des Sciences). The tenth child of a glove-maker, he grew up poor, and in his youth he reportedly aspired to become a clockmaker. He studied under the Jesuits and later joined the Order of the Minims in Lyon. It was his intention at the time to follow a course of religious studies, but he regained his interest in mechanical devices after meeting the surgeon Claude-Nicolas L ...

Mechanism (technology)
In engineering, a mechanism is a device that transforms input forces and movement into a desired set of output forces and movement. Mechanisms generally consist of moving components which may include: * Gears and gear trains; * Belts and chain drives; * Cams and followers; * Linkages; * Friction devices, such as brakes or clutches; * Structural components such as a frame, fasteners, bearings, springs, or lubricants; * Various machine elements, such as splines, pins, or keys. The German scientist Franz Reuleaux defines ''machine'' as "a combination of resistant bodies so arranged that by their means the mechanical forces of nature can be compelled to do work accompanied by certain determinate motion". In this context, his use of ''machine'' is generally interpreted to mean ''mechanism''. The combination of force and movement defines power, and a mechanism manages power to achieve a desired set of forces and movement. A mechanism is usually a piece of a larger process, know ...

Louis XI Of France
Louis XI (3 July 1423 – 30 August 1483), called "Louis the Prudent" (french: le Prudent), was King of France from 1461 to 1483. He succeeded his father, Charles VII. Louis entered into open rebellion against his father in a short-lived revolt known as the Praguerie in 1440. The king forgave his rebellious vassals, including Louis, to whom he entrusted the management of the Dauphiné, then a province in southeastern France. Louis's ceaseless intrigues, however, led his father to banish him from court. From the Dauphiné, Louis led his own political establishment and married Charlotte of Savoy, daughter of Louis, Duke of Savoy, against the will of his father. Charles VII sent an army to compel his son to his will, but Louis fled to Burgundy, where he was hosted by Philip the Good, the Duke of Burgundy, Charles' greatest enemy. When Charles VII died in 1461, Louis left the Burgundian court to take possession of his kingdom. His taste for intrigue and his intense diplomatic a ...
