Philip Vaughan
Philip Vaughan was a Welsh inventor and ironmaster who patented the first design for a ball bearing in 1794. Vaughan's patent described how iron balls could be placed between the wheel and the axle of a carriage. The balls let the carriage wheels rotate freely by reducing friction. Vaughan was granted a patent in 1794 for a ball bearing that sits between the axle and the wheel on a carriage. His design has the balls running inside deep grooves, and sealed in place with a stopper. Bearings are used in most rotating machines in the modern world - found throughout the rotating parts in cars, bikes, trains, planes etc. These modern ball bearings work in much the same way as Vaughan's initial invention. They make vehicles more efficient by reducing the friction between the moving parts. Without bearings, our mechanical world would simply not work. Vaughan was a proprietor and agent of the iron foundry at Carmarthen and Kidwelly. He owned one house called Green Hall in the Four ...

Thumb IMG 1074 1024
The thumb is the first digit of the hand, next to the index finger. When a person is standing in the medical anatomical position (where the palm is facing to the front), the thumb is the outermost digit. The Medical Latin English noun for thumb is ''pollex'' (compare ''hallux'' for big toe), and the corresponding adjective for thumb is ''pollical''. Definition Thumb and fingers The English word ''finger'' has two senses, even in the context of appendages of a single typical human hand: # Any of the five terminal members of the hand. # Any of the four terminal members of the hand, other than the thumb Linguistically, it appears that the original sense was the first of these two: (also rendered as ) was, in the inferred Proto-Indo-European language, a suffixed form of (or ), which has given rise to many Indo-European-family words (tens of them defined in English dictionaries) that involve, or stem from, concepts of fiveness. The thumb shares the following with each of the ot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wales
Wales ( cy, Cymru ) is a Countries of the United Kingdom, country that is part of the United Kingdom. It is bordered by England to the Wales–England border, east, the Irish Sea to the north and west, the Celtic Sea to the south west and the Bristol Channel to the south. It had a population in 2021 of 3,107,500 and has a total area of . Wales has over of coastline and is largely mountainous with its higher peaks in the north and central areas, including Snowdon (), its highest summit. The country lies within the Temperateness, north temperate zone and has a changeable, maritime climate. The capital and largest city is Cardiff. Welsh national identity emerged among the Celtic Britons after the Roman withdrawal from Britain in the 5th century, and Wales was formed as a Kingdom of Wales, kingdom under Gruffydd ap Llywelyn in 1055. Wales is regarded as one of the Celtic nations. The Conquest of Wales by Edward I, conquest of Wales by Edward I of England was completed by 1283, th ...

Ironmaster
An ironmaster is the manager, and usually owner, of a forge or blast furnace for the processing of iron. It is a term mainly associated with the period of the Industrial Revolution, especially in Great Britain. The ironmaster was usually a large scale entrepreneur and thus an important member of a community. He would have a large country house or mansion as his residence. The organization of operations surrounding the smelting, refining and casting of iron was labour-intensive, and so there would be numerous workers reliant on the furnace works. There were ironmasters (possibly not called such) from the 17th century onwards, but they became more prominent with the great expansion in the British iron industry during the Industrial Revolution. 17th century ironmasters (examples) An early ironmaster was John Winter (Royalist), John Winter (about 1600–1676) who owned substantial holdings in the Forest of Dean. During the English Civil War he cast cannons for Charles I of England ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Ball Bearing
A ball bearing is a type of rolling-element bearing that uses balls to maintain the separation between the bearing races. The purpose of a ball bearing is to reduce rotational friction and support radial and axial loads. It achieves this by using at least two races to contain the balls and transmit the loads through the balls. In most applications, one race is stationary and the other is attached to the rotating assembly (e.g., a hub or shaft). As one of the bearing races rotates it causes the balls to rotate as well. Because the balls are rolling they have a much lower coefficient of friction than if two flat surfaces were sliding against each other. Ball bearings tend to have lower load capacity for their size than other kinds of rolling-element bearings due to the smaller contact area between the balls and races. However, they can tolerate some misalignment of the inner and outer races. History Although bearings had been developed since ancient times, the first mod ...

Carmarthen
Carmarthen (, RP: ; cy, Caerfyrddin , "Merlin's fort" or "Sea-town fort") is the county town of Carmarthenshire and a community in Wales, lying on the River Towy. north of its estuary in Carmarthen Bay. The population was 14,185 in 2011, down from 15,854 in 2001, but gauged at 16,285 in 2019. It has a claim to be the oldest town in Wales – ''Old Carmarthen'' and ''New Carmarthen'' became one borough in 1546. It was the most populous borough in Wales in the 16th–18th centuries, described by William Camden as "chief citie of the country". Growth stagnated by the mid-19th century as new settlements developed in the South Wales Coalfield. History Early history When Britannia was a Roman province, Carmarthen was the civitas capital of the Demetae tribe, known as Moridunum ("Sea Fort"). It is possibly the oldest town in Wales, recorded by Ptolemy and in the Antonine Itinerary. The Roman fort is believed to date from about AD 75. A Roman coin hoard was found nearby in 20 ...

Kidwelly
Kidwelly ( cy, Cydweli) is a town and community in Carmarthenshire, southwest Wales, approximately northwest of the most populous town in the county, Llanelli. In the 2001 census the community of Kidwelly returned a population of 3,289, increasing to 3,523 at the 2011 Census. It lies on the River Gwendraeth above Carmarthen Bay. The community includes Mynyddgarreg and Llangadog. History The earliest written form of the name, 'Cetgueli', is recorded by the monk, Nennius, writing in the 9th century. One theory is that the name means the land, territory, or kingdom of Cadwal. Another theory is that the name is the combination of the two words ''Cyd'' (joint) and ''Gweli'' (bed), i.e., the joining of the two river beds Gwendraeth Fawr and Gwendraeth Fach, wherein Cydweli lies. The town itself is ancient and is shrouded in mystery of its founding, but the most popular theory is that it was founded by local warlords since the area was part of the Ystrad Tywi.

St Peter's Church, Carmarthen
St Peter's Church (Welsh: ''Eglwys San Pedr'') is the Church in Wales parish church for the town of Carmarthen, Wales. Though founded much earlier, the present building dates from at least the 14th century. It is the largest church in the Diocese of St David's and is a Grade I listed building. It is also the oldest surviving building in Carmarthen. History It is not known whether an older, pre-Norman church originally stood on the site, but St Peter's lies within the site of Roman Moridinum, inside the presumed west gate of the Roman walls. The church, if founded soon after the construction of the Norman castle, was located midway between the castle and the monastic settlement of Llandeulyddog, which is known to have existed before the Norman Conquest. Its location would have allowed it to serve the spiritual needs of both the Welsh community Old Carmarthen, and New Carmarthen which developed in the shadow of the castle. St Peter's Church is recorded as being transferred to Batt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Copartnership
A partnership is an arrangement where parties, known as business partners, agree to cooperate to advance their mutual interests. The partners in a partnership may be individuals, businesses, interest-based organizations, schools, governments or combinations. Organizations may partner to increase the likelihood of each achieving their mission and to amplify their reach. A partnership may result in issuing and holding equity or may be only governed by a contract. History Partnerships have a long history; they were already in use in medieval times in Europe and in the Middle East. According to a 2006 article, the first partnership was implemented in 1383 by Francesco di Marco Datini, a merchant of Prato and Florence. The Covoni company (1336-40) and the Del Buono-Bencivenni company (1336-40) have also been referred to as early partnerships, but they were not formal partnerships. In Europe, the partnerships contributed to the Commercial Revolution which started in the 13th centur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Watercourse
A stream is a continuous body of surface water flowing within the bed and banks of a channel. Depending on its location or certain characteristics, a stream may be referred to by a variety of local or regional names. Long large streams are usually called rivers, while smaller, less voluminous and more intermittent streams are known as streamlets, brooks or creeks. The flow of a stream is controlled by three inputs – surface runoff (from precipitation or meltwater), daylighted subterranean water, and surfaced groundwater (spring water). The surface and subterranean water are highly variable between periods of rainfall. Groundwater, on the other hand, has a relatively constant input and is controlled more by long-term patterns of precipitation. The stream encompasses surface, subsurface and groundwater fluxes that respond to geological, geomorphological, hydrological and biotic controls. Streams are important as conduits in the water cycle, instruments in groundwater ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mayor
In many countries, a mayor is the highest-ranking official in a municipal government such as that of a city or a town. Worldwide, there is a wide variance in local laws and customs regarding the powers and responsibilities of a mayor as well as the means by which a mayor is elected or otherwise mandated. Depending on the system chosen, a mayor may be the chief executive officer of the municipal government, may simply chair a multi-member governing body with little or no independent power, or may play a solely ceremonial role. A mayor's duties and responsibilities may be to appoint and oversee municipal managers and employees, provide basic governmental services to constituents, and execute the laws and ordinances passed by a municipal governing body (or mandated by a state, territorial or national governing body). Options for selection of a mayor include direct election by the public, or selection by an elected governing council or board. The term ''mayor'' shares a linguistic ...

Brecon
Brecon (; cy, Aberhonddu; ), archaically known as Brecknock, is a market town in Powys, mid Wales. In 1841, it had a population of 5,701. The population in 2001 was 7,901, increasing to 8,250 at the 2011 census. Historically it was the county town of Brecknockshire (Breconshire); although its role as such was eclipsed with the formation of the County of Powys, it remains an important local centre. Brecon is the third-largest town in Powys, after Newtown and Ystradgynlais. It lies north of the Brecon Beacons mountain range, but is just within the Brecon Beacons National Park. History Early history The Welsh name, Aberhonddu, means "mouth of the Honddu". It is derived from the River Honddu, which meets the River Usk near the town centre, a short distance away from the River Tarell which enters the Usk a few hundred metres upstream. After the Dark Ages the original Welsh name of the kingdom in whose territory Brecon stands was (in modern orthography) "Brycheiniog", whi ...
