Science
Science is a systematic endeavor that Scientific method, builds and organizes knowledge in the form of Testability, testable explanations and predictions about the universe. Science may be as old as the human species, and some of the earliest archeological evidence for scientific reasoning is tens of thousands of years old. The earliest written records in the history of science come from Ancient Egypt and Mesopotamia in around 3000 to 1200 Common Era, BCE. Their contributions to mathematics, astronomy, and medicine entered and shaped Greek natural philosophy of classical antiquity, whereby formal attempts were made to provide explanations of events in the Universe, physical world based on natural causes. After the fall of the Western Roman Empire, knowledge of History of science in classical antiquity, Greek conceptions of the world deteriorated in Western Europe during the early centuries (400 to 1000 CE) of the Middle Ages, but was preserved in the Muslim world during the ...

Column Still
A column still, also called a continuous still, patent still or Coffey still is a variety of still consisting of two columns. Column stills can produce rectified spirit (95% ABV). Description The first column (called the analyzer) in a column still has steam rising and wash descending through several levels. The second column (called the rectifier) carries the alcohol from the wash, where it circulates until it can condense at the required strength. A column still is an example of a fractional distillation, in that it yields a narrow fraction of the distillable components. This technique is frequently employed in chemical synthesis; in this case, the component of the still responsible for the separation is a fractionating column. A continuous still can, as its name suggests, sustain a constant process of distillation. This, along with the ability to produce a higher concentration of alcohol in the final distillate, is its main advantage over a pot still, which can only work in ...

Aeneas Coffey
Aeneas Coffey (1780–1839) was an Irish inventor and distiller. Biography Coffey was born in 1780. According to some sources he was born in Ireland most likely in Co. Dublin or Co. Wicklow. Some references refer to his birth in Calais, France, in 1780 to Irish parents. Coffey was educated at Trinity College Dublin and entered the excise service around 1799–1800 as a gauger. He married Susanna Logie in 1808, and they had three sons over the next eight years: Aeneas, William and Philip. Customs and excise officer Coffey was appointed sub-commissioner of Inland Excise and Taxes for the district of Drogheda in 1813. He was appointed Surveyor of Excise for Clonmel and Wicklow in 1815. In 1816 he was promoted to the same post at Cork. By 1818 he was Acting Inspector General of Excise for the whole of Ireland and within two years was promoted to Inspector General of Excise in Dublin, Ireland. He was a strong, determined upholder of the law, but aware of its shortcomings. He sur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lawnmower
A lawn mower (also known as a mower, grass cutter or lawnmower) is a device utilizing one or more revolving blades (or a reel) to cut a grass surface to an even height. The height of the cut grass may be fixed by the design of the mower, but generally is adjustable by the operator, typically by a single master lever, or by a lever or nut and bolt on each of the machine's wheels. The blades may be powered by manual force, with wheels mechanically connected to the cutting blades so that when the mower is pushed forward, the blades spin or the machine may have a battery-powered or plug-in electric motor. The most common self-contained power source for lawn mowers is a small (typically one cylinder) internal combustion engine. Smaller mowers often lack any form of propulsion, requiring human power to move over a surface; "walk-behind" mowers are self-propelled, requiring a human only to walk behind and guide them. Larger lawn mowers are usually either self-propelled "walk-behind" ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Edwin Beard Budding
Edwin Beard Budding (25 August 1796 – 25 September 1846), an engineer born in Eastington, Stroud, was the English inventor of the lawnmower (1830) and adjustable spanner (1842). Lawnmower Budding had the idea of the lawnmower after seeing a machine in a local cloth mill which used a cutting cylinder (or bladed reel) mounted on a bench to trim the irregular nap from the surface of woollen cloth and give a smooth finish. Budding's mower was designed primarily to cut the lawn on sports grounds and extensive gardens, as a superior alternative to the scythe, and was granted a British patent on 31 August 1830. It took ten more years and further innovations to create a machine that could be worked by animals, and sixty years before a steam-powered lawn mower was built. The first machine produced was 19 inches in width with a frame made of wrought iron. The mower was pushed from behind with motive power coming from the rear land roller which drove gears to transfer the drive to the kniv ...

Rack Railway
A rack railway (also rack-and-pinion railway, cog railway, or cogwheel railway) is a steep grade railway with a toothed rack rail, usually between the running rails. The trains are fitted with one or more cog wheels or pinions that mesh with this rack rail. This allows the trains to operate on steep grades above 10%, which is the maximum for friction-based rail. Most rack railways are mountain railways, although a few are transit railways or tramways built to overcome a steep gradient in an urban environment. The first cog railway was the Middleton Railway between Middleton and Leeds in West Yorkshire, England, United Kingdom, where the first commercially successful steam locomotive, '' Salamanca'', ran in 1812. This used a rack and pinion system designed and patented in 1811 by John Blenkinsop. The first mountain cog railway was the Mount Washington Cog Railway in the U.S. state of New Hampshire, which carried its first fare-paying passengers in 1868. The track was comp ...

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 ...
