Hydraulic Ram
A hydraulic ram pump, ram pump, or hydram is a cyclic pump, cyclic water pump powered by hydropower. It takes in water at one "hydraulic head" (pressure) and flow rate, and outputs water at a higher hydraulic head and lower flow rate. The device uses the water hammer effect to develop pressure that allows a portion of the input water that powers the pump to be lifted to a point higher than where the water originally started. The hydraulic ram is sometimes used in remote areas, where there is both a source of Low head hydro power, low-head hydropower and a need for pumping water to a destination higher in elevation than the source. In this situation, the ram is often useful, since it requires no outside source of Power (physics), power other than the kinetic energy of flowing water. History In 1772, John Whitehurst of Cheshire, England, invented a manually controlled precursor of the hydraulic ram called the "pulsation engine" and installed the first one at Oulton, Cheshir ...

Cyclic Pump
A Cyclic pump is an apparatus which moves a fluid in a periodic uni-directional direction from one containment system to another while overcoming static conditions that would, without intervention, not move. The intervention predicated by the pump alters pressures, volumes and sometimes temperatures of fluids (gaseous, liquid, colloidal, plasmic, etc.) in such a way that the fluids are transported to other chambers or enclosures (including pipes), thus "flowing" in a consistent direction, usually having characteristics of pulsation (as is the case with the Human heart) or of uniform motion (as is the case with an Automobile motor oil pump). Cyclic pumps are generally incorporated into machines to deal with all sorts of fluids associated with that machine's functionality.

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 sufficiency of disclosure, 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 la ...

Toller Whelme
Toller Whelme is a small hamlet in Dorset, England, situated in the civil parish of Corscombe approximately east of Beaminster, north of Bridport and north-west of Dorchester. There are seven homes in the hamlet: West Farm, Norcombe Hayes, Manor House, 1 & 2 West Farm Cottages, East Farm and Lake Farm. Toller Whelme takes its name from the River Toller (the former name of the present River Hooke), at the source of which it stands: the second element ''Whelme'' means ''river source'' or ''spring'' in Anglo-Saxon. It has occasionally in the past also been known as ''Pinny's Toller'' or ''Penny Toller'', from the name of the landowning Pinney family formerly established here at the manor house. The Manor House was once the principal residence of a single estate farmstead which has been subsequently divided into separate properties and holdings. The Manor was once a grange farm of Forde Abbey near Chard. Older buildings in the hamlet include the Manor House, a nearby conv ...

English Country House
image:Blenheim - Blenheim Palace - 20210417125239.jpg, 300px, Blenheim Palace - Oxfordshire An English country house is a large house or mansion in the English countryside. Such houses were often owned by individuals who also owned a Townhouse (Great Britain), town house. This allowed them to spend time in the country and in the city—hence, for these people, the term distinguished between town and country. However, the term also encompasses houses that were, and often still are, the full-time residence for the landed gentry who dominated rural Britain until the Reform Act 1832. Frequently, the formal business of the Historic counties of England, counties was transacted in these country houses, having functional antecedents in manor houses. With large numbers of indoor and outdoor staff, country houses were important as places of employment for many rural communities. In turn, until the Great Depression of British Agriculture, agricultural depressions of the 1870s, the est ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drainage
Drainage is the natural or artificial removal of a surface's water and sub-surface water from an area with excess water. The internal drainage of most agricultural soils can prevent severe waterlogging (anaerobic conditions that harm root growth), but many soils need artificial drainage to improve production or to manage water supplies. History Early history The Indus Valley Civilization had sewerage and drainage systems. All houses in the major cities of Harappa and Mohenjo-daro had access to water and drainage facilities. Waste water was directed to covered gravity sewers, which lined the major streets. 18th and 19th century The invention of hollow-pipe drainage is credited to Sir Hugh Dalrymple, who died in 1753. Current practices Simple infrastructure such as open drains, pipes, and berms are still common. In modern times, more complex structures involving substantial earthworks and new technologies have been common as well. Geotextiles New storm water drainag ...

Sanitary Sewer
A sanitary sewer is an underground pipe or tunnel system for transporting sewage from houses and commercial buildings (but not stormwater) to a sewage treatment plant or disposal. Sanitary sewers are a type of gravity sewer and are part of an overall system called a "sewage system" or sewerage. Sanitary sewers serving industrial areas may also carry industrial wastewater. In municipalities served by sanitary sewers, separate storm drains may convey surface runoff directly to surface waters. An advantage of sanitary sewer systems is that they avoid combined sewer overflows. Sanitary sewers are typically much smaller in diameter than combined sewers which also transport urban runoff. Backups of raw sewage can occur if excessive stormwater inflow or groundwater infiltration occurs due to leaking joints, defective pipes etc. in aging infrastructure. Purpose Sewage treatment is less effective when sanitary waste is diluted with stormwater, and combined sewer overflows occu ...

Josiah Easton
Josiah () or Yoshiyahu was the 16th king of Judah (–609 BCE). According to the Hebrew Bible, he instituted major religious reforms by removing official worship of gods other than Yahweh. Until the 1990s, the biblical description of Josiah’s reforms were usually considered to be more or less accurate, but that is now heavily debated. According to the Bible, Josiah became king of the Kingdom of Judah at the age of eight, after the assassination of his father, King Amon, and reigned for 31 years, from 641/640 to 610/609 BCE. Josiah is known only from biblical texts; no reference to him exists in other surviving texts of the period from ancient Egypt or Babylon, and no clear archaeological evidence, such as inscriptions bearing his name, has ever been found. However, a seal bearing the name " Nathan-melech," the name of an administrative official under King Josiah according to , dating to the 7th century BCE, was found in situ in an archeological site in Jerusalem.

Matthew Boulton
Matthew Boulton ( ; 3 September 172817 August 1809) was an English businessman, inventor, mechanical engineer, and silversmith. He was a business partner of the Scottish engineer James Watt. In the final quarter of the 18th century, the partnership installed hundreds of Boulton and Watt, Boulton & Watt steam engines, which were a great advance on the state of the art, making possible the mechanisation of factories and mills. Boulton applied modern techniques to the minting of coins, striking millions of pieces for Britain and other countries, and supplying the Royal Mint with up-to-date equipment. Born in Birmingham, he was the son of a Birmingham manufacturer of small metal products who died when Boulton was 31. By then Boulton had managed the business for several years, and thereafter expanded it considerably, consolidating operations at the Soho Manufactory, built by him near Birmingham. At Soho, he adopted the latest techniques, branching into silver plate, ormolu ("gilt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
