Holman Bros Ltd
Holman Brothers Ltd. was a mining equipment manufacturer founded in 1801 based in Camborne, Cornwall, England. Holman was Camborne's, and indeed Cornwall's largest manufacturer of industrial equipment. Holman played a part in World War II making the Polish designed 20mm Polsten gun, similar to the Oerlikon but simpler to build and use. It also produced the Holman Projector for the Royal Navy. At its height Holmans was spread over three sites within Camborne, employing some three and half thousand people. Cornish mining is renowned worldwide. Alongside the mining industry there evolved an industry manufacturing specialised mining equipment. Holman's founder, Nicholas Holman started a boiler works in 1801.

Piston
A piston is a component of reciprocating engines, reciprocating pumps, gas compressors, hydraulic cylinders and pneumatic cylinders, among other similar mechanisms. It is the moving component that is contained by a cylinder and is made gas-tight by piston rings. In an engine, its purpose is to transfer force from expanding gas in the cylinder to the crankshaft via a piston rod and/or connecting rod. In a pump, the function is reversed and force is transferred from the crankshaft to the piston for the purpose of compressing or ejecting the fluid in the cylinder. In some engines, the piston also acts as a valve by covering and uncovering ports in the cylinder. __TOC__ Piston engines Internal combustion engines An internal combustion engine is acted upon by the pressure of the expanding combustion gases in the combustion chamber space at the top of the cylinder. This force then acts downwards through the connecting rod and onto the crankshaft. The connecting rod is att ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Former Defence Companies Of The United Kingdom
A former is an object, such as a template, gauge or cutting die, which is used to form something such as a boat's hull. Typically, a former gives shape to a structure that may have complex curvature. A former may become an integral part of the finished structure, as in an aircraft fuselage, or it may be removable, being using in the construction process and then discarded or re-used. Aircraft formers Formers are used in the construction of aircraft fuselage, of which a typical fuselage has a series from the nose to the empennage, typically perpendicular to the longitudinal axis of the aircraft. The primary purpose of formers is to establish the shape of the fuselage and reduce the column length of stringers to prevent instability. Formers are typically attached to longerons, which support the skin of the aircraft. The "former-and-longeron" technique (also called stations and stringers) was adopted from boat construction, and was typical of light aircraft built until the ad ...

Engineering Companies Of The United Kingdom
Engineering is the use of scientific principles to design and build machines, structures, and other items, including bridges, tunnels, roads, vehicles, and buildings. The discipline of engineering encompasses a broad range of more specialized fields of engineering, each with a more specific emphasis on particular areas of applied mathematics, applied science, and types of application. See glossary of engineering. The term ''engineering'' is derived from the Latin ''ingenium'', meaning "cleverness" and ''ingeniare'', meaning "to contrive, devise". Definition The American Engineers' Council for Professional Development (ECPD, the predecessor of ABET) has defined "engineering" as: The creative application of scientific principles to design or develop structures, machines, apparatus, or manufacturing processes, or works utilizing them singly or in combination; or to construct or operate the same with full cognizance of their design; or to forecast their behavior under specif ...

Mining In Cornwall
Mining in Cornwall and Devon, in the southwest of England, began in the early Bronze Age, around 2150 BC. Tin, and later copper, were the most commonly extracted metals. Some tin mining continued long after the mining of other metals had become unprofitable, but ended in the late 20th century. In 2021, it was announced that a new mine was extracting battery-grade lithium carbonate, more than 20 years after the closure of the last South Crofty tin mine in Cornwall in 1998. Historically, tin and copper as well as a few other metals (e.g. arsenic, silver, and zinc) have been mined in Cornwall and Devon. Tin deposits still exist in Cornwall, and there has been talk of reopening the South Crofty tin mine. In addition, work has begun on re-opening the Hemerdon tungsten and tin mine in south-west Devon. In view of the economic importance of mines and quarries, geological studies have been conducted; about forty distinct minerals have been identified from type localities in Cornwa ...

History Of Cornwall
The history of Cornwall goes back to the Paleolithic, but in this period Cornwall only had sporadic visits by groups of humans. Continuous occupation started around 10,000 years ago after the end of the last ice age. When recorded history started in the first century BCE, the spoken language was Common Brittonic, and that would develop into Southwestern Brittonic and then the Cornish language. Cornwall was part of the territory of the tribe of the Dumnonii that included modern-day Devon and parts of Somerset. After a period of Roman rule, Cornwall reverted to rule by independent Romano-British leaders and continued to have a close relationship with Brittany and Wales as well as southern Ireland, which neighboured across the Celtic Sea. After the collapse of Dumnonia, the remaining territory of Cornwall came into conflict with neighbouring Wessex. By the middle of the ninth century, Cornwall had fallen under the control of Wessex, but it kept its own culture. In 1337, th ...

Mining In The United Kingdom
Mining in the United Kingdom produces a wide variety of fossil fuels, metals, and industrial minerals due to its complex geology. In 2013, there were over 2,000 active mines, quarries, and offshore drilling sites on the continental land mass of the United Kingdom producing £34bn of minerals and employing 36,000 people. Brief history The United Kingdom has a rich history of mining. Mining of non-ferrous minerals, particularly of copper and tin, has been ongoing since the Bronze Age. For example, copper was mined in Wales during approximately 2200–850 BC. Metalworking debris found beneath the ramparts at Beeston Castle in Cheshire is evidence of bronze production during the Bronze Age. Later, lead and copper attracted the Romans to Britain. The Romans introduced iron tools and used local slaves to mine galena, an important lead ore mineral, from which they refined lead, tin and silver. These metals were used locally and also transported by ship throughout the Roman Empire. Gal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trevithick Society
The Trevithick Society is a registered charity named for Richard Trevithick, a Cornish engineer who contributed to the use of high pressure steam engines for transportation and mining applications. History In 1935 the Cornish Engines Preservation Committee (CEPC) was formed to rescue the Levant winding engine which was deemed outdated and scheduled to be scrapped. CEPC were forerunners in the field of Industrial Archaeology. They acquired another winding engine and two pumping engines. CEPC merged with the newly formed Cornish Waterwheel Preservation Society in 1971 and named the organisation the Trevithick Society after Richard Trevithick. Chapel Coombe At Chapel Coombe a set of old Cornish stamps has been re-erected by the Trevithick Society.
