Dunlop Pneumatic Tyre Company
Dunlop Ltd. (formerly Dunlop Rubber) was a British multinational company involved in the manufacture of various natural rubber goods. Its business was founded in 1889 by Harvey du Cros and he involved John Boyd Dunlop who had re-invented and developed the first pneumatic tyre. It was one of the first multinationals, and under du Cros and, after him, under Eric Geddes, grew to be one of the largest British industrial companies. J B Dunlop had dropped any ties to it well before his name was used for any part of the business. The business and manufactory was founded in Upper Stephens Street in Dublin. A plaque marks the site, which is now part of the head office of the Irish multinational departments store brand, Dunnes Stores. Dunlop Rubber failed to adapt to evolving market conditions in the 1970s, despite having recognised by the mid-1960s the potential drop in demand as the more durable radial tyres swept through the market. After taking on excessive debt Dunlop was acquired ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BTR Plc
BTR plc was a British multinational industrial conglomerate company headquartered in London, United Kingdom. It was founded in 1924, grew strongly by acquisition under Sir Owen Green's leadership, and merged with Siebe plc in 1999 to form BTR Siebe plc, later renamed Invensys. BTR was listed on the London Stock Exchange and was once a constituent of the FTSE 100 Index. Invensys was bought by and absorbed into Schneider Electric in 2014.

Drysuit
A dry suit or drysuit provides the wearer with environmental protection by way of thermal insulation and exclusion of water, and is worn by divers, boaters, water sports enthusiasts, and others who work or play in or near cold or contaminated water. A dry suit normally protects the whole body except the head, hands, and possibly the feet. In hazmat configurations, however, all of these are covered as well. The main difference between dry suits and wetsuits is that dry suits are designed to prevent water from entering. This generally allows better insulation, making them more suitable for use in cold water. Dry suits can be uncomfortably hot in warm or hot air, and are typically more expensive and more complex to don. For divers, they add some degree of operational complexity and hazard as the suit must be inflated and deflated with changes in depth in order to minimize "squeeze" on descent or uncontrolled rapid ascent due to excessive buoyancy, which requires additional skills ...

Safety Bicycle
A safety bicycle (or simply a safety) is a type of bicycle that became very popular beginning in the late 1880s as an alternative to the penny-farthing ("ordinary") and is now the most common type of bicycle. Early bicycles of this style were known as safety bicycles because they were noted for, and marketed as, being safer than the high wheelers they were replacing. Even though modern bicycles use a similar design, the term is rarely used today and is considered obsolete outside circles familiar with high wheelers. Definition The term 'safety bicycle' was used in the 1880s for any alternative to the penny-farthing. The front and rear wheel were not necessarily the same size. Later historians began to use the term in a more restricted way for the design that was a direct ancestor to most modern bicycles. " Diamond frame" is also sometimes used as a term for safety bicycles, even though this technically only refers to a certain type of safety bicycle. The retronym "upright bicyc ...

John Kemp Starley
John Kemp Starley (24 December 1855 – 29 October 1901) was an English inventor and industrialist who is widely considered the inventor of the modern bicycle, and also originator of the name Rover. Early life Born on 24 December 1855 Starley lived on Church Hill, Walthamstow, London, England. He was the son of a gardener, John Starley, and Mary Ann (née Cippen).Biography at Vestry House Museum, Walthamstow In 1872 he moved to Coventry to work with his uncle James Starley, an inventor. He worked with his uncle and William Hillman for several years building Ariel cycles. Career In 1877, he started a new business ''Starley & Sutton Co'' with William Sutton, a local cycling enthusiast. They set about developing bicycles that were safer and easier to use than the prevailing penny farthing or "ordinary" bicycles. They started by manufacturing tricycles, and by 1883 their products were being branded as "Rover". In 1885, Starley made history when he produced the Rover Safe ...

Willie Hume
William Hume (3 April 1862 – 1941The Bicycle, 12 Nov 1941, p6) was an Irish cyclist. He demonstrated the supremacy of John Boyd Dunlop's newly invented pneumatic tyres in 1889, winning the tyre's first ever races in Ireland and then England. Career In March 1889 Hume, the captain of the Belfast Cruisers Cycling Club, was the first member of the public to purchase a "safety bicycle" fitted with Dunlop's newly patented pneumatic tyres. Dunlop suggested that it would be advantageous to Hume to use them in a race. Thus on 18 May 1889 he won all four cycling events at the Queen's College Sports held on the North of Ireland Cricket Club Grounds, (or Queens College playing fields) at Cherryvale, Belfast. Entrepreneur and paper manufacturer Harvey du Cros was present at the meet, and was so impressed that within six months he had acquired the patent rights (or in 1896) for £3,000 and floated the first Pneumatic Tyre Company. Hume went on to be the person to introduce the new ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Boyd Dunlop
John Boyd Dunlop (5 February 1840 – 23 October 1921) was a Scottish-born inventor and veterinary surgeon who spent most of his career in Ireland. Familiar with making rubber devices, he invented the first practical pneumatic tyres for his child's tricycle and developed them for use in cycle racing. He sold his rights to the pneumatic tyres to a company he formed with the president of the Irish Cyclists' Association, Harvey Du Cros, for a small cash sum and a small shareholding in their pneumatic tyre business. Dunlop withdrew in 1896. The company that bore his name, Dunlop Pneumatic Tyre Company, was not incorporated until later using the name well known to the public, but it was Du Cros's creation. Veterinary practice He was born on a farm in Dreghorn, North Ayrshire, and studied to be a veterinary surgeon at the Dick Vet, University of Edinburgh, moving to Downpatrick, Ireland in 1867. Quite early in his life he was told he had been a premature birth, two months bef ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radial Tire
A radial tire (more properly, a radial-ply tire) is a particular design of vehicular tire. In this design, the cord plies are arranged at 90 degrees to the direction of travel, or radially (from the center of the tire). Radial tire construction climbed to 100% market share in North America following Consumer Reports finding the superiority of the radial design in 1968, and were standard by 1976. History The first radial tire designs were patented in 1914 by G.H. Hamilton and T. Sloper -patent № 467 filed in London, and in 1916 by Arthur W. Savage, a tire manufacturer (1915–1919), firearm designer and inventor in San Diego, CA - . No actual products were created. Michelin in France designed, developed, patented, and commercialized the radial tire. The first Michelin X radial tire for cars was developed in 1946 by Michelin researcher Marius Mignol. There is no evidence that the former accountant turned researcher Mignol had knowledge of Hamilton or Savage's earlier work wh ...

Pneumatic Tyre
Pneumatics (from Greek ‘wind, breath’) is a branch of engineering that makes use of gas or pressurized air. Pneumatic systems used in industry are commonly powered by compressed air or compressed inert gases. A centrally located and electrically-powered compressor powers cylinders, air motors, pneumatic actuators, and other pneumatic devices. A pneumatic system controlled through manual or automatic solenoid valves is selected when it provides a lower cost, more flexible, or safer alternative to electric motors, and hydraulic actuators. Pneumatics also has applications in dentistry, construction, mining, and other areas. Gases used in pneumatic systems Pneumatic systems in fixed installations, such as factories, use compressed air because a sustainable supply can be made by compressing atmospheric air. The air usually has moisture removed, and a small quantity of oil is added at the compressor to prevent corrosion and lubricate mechanical components. Factory-plumbed ...

Natural Rubber
Rubber, also called India rubber, latex, Amazonian rubber, ''caucho'', or ''caoutchouc'', as initially produced, consists of polymers of the organic compound isoprene, with minor impurities of other organic compounds. Thailand, Malaysia, and Indonesia are three of the leading rubber producers. Types of polyisoprene that are used as natural rubbers are classified as elastomers. Currently, rubber is harvested mainly in the form of the latex from the rubber tree (''Hevea brasiliensis'') or others. The latex is a sticky, milky and white colloid drawn off by making incisions in the bark and collecting the fluid in vessels in a process called "tapping". The latex then is refined into the rubber that is ready for commercial processing. In major areas, latex is allowed to coagulate in the collection cup. The coagulated lumps are collected and processed into dry forms for sale. Natural rubber is used extensively in many applications and products, either alone or in combination wit ...
