Central Tramway Company, Scarborough
The Central Tramway Company is an electric-powered funicular railway located in the holiday resort of Scarborough, North Yorkshire. The company has the distinction of being the oldest surviving Tramway Company in the UK, as the original corporation still operates the funicular today. Built in just 6 months between January and August 1881, the Tramway opened on Monday 1 August becoming the 3rd such cliff railway to operate in the borough. The distinctive burgundy and cream carriages travel up and down the track between the bottom station on Foreshore Road, next to the beach and tourist arcades, and the top station on Marine Parade, close to the town centre. History Origin Scarborough developed from a fishing town into a busy Spa Town and tourist resort through the 18th and 19th centuries, thanks in part to the discovery of the acidic water running into the South Bay by Thomasin Farrer in the 17th century. Visitors were drawn to the town for the health benefits of both the spa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Funicular
A funicular (, , ) is a type of cable railway system that connects points along a railway track laid on a steep slope. The system is characterized by two counterbalanced carriages (also called cars or trains) permanently attached to opposite ends of a haulage cable, which is looped over a pulley at the upper end of the track. The result of such a configuration is that the two carriages move synchronously: as one ascends, the other descends at an equal speed. This feature distinguishes funiculars from inclined elevators, which have a single car that is hauled uphill. The term ''funicular'' derives from the Latin word , the diminutive of , meaning 'rope'. Operation In a funicular, both cars are permanently connected to the opposite ends of the same cable, known as a ''haul rope''; this haul rope runs through a system of pulleys at the upper end of the line. If the railway track is not perfectly straight, the cable is guided along the track using sheaves – unpowered pulleys tha ...

Crossley
Crossley, based in Manchester, United Kingdom, was a pioneering company in the production of internal combustion engines. Since 1988 it has been part of the Rolls-Royce Power Engineering group. More than 100,000 Crossley oil and gas engines have been built. History Crossley Brothers Crossley Brothers was set up in 1867 by brothers Francis (1839–97) and William J.(1844–1911). Francis, with help from his uncle, bought the engineering business of John M Dunlop at Great Marlborough Street in Manchester city centre, including manufacturing pumps, presses, and small steam engines. William (''Sir'' William from 1910 – Baronet) joined his brother shortly after the purchase. The company name was initially changed to Crossley Brothers and Dunlop. Each of the brothers had served engineering apprenticeships: Francis, known as Frank, at Robert Stephenson and Company; and William at W.G. Armstrong, both in Newcastle upon Tyne. William concentrated on the business side, Frank provi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Programmable Logic Controller
A programmable logic controller (PLC) or programmable controller is an industrial computer that has been ruggedized and adapted for the control of manufacturing processes, such as assembly lines, machines, robotic devices, or any activity that requires high reliability, ease of programming, and process fault diagnosis. Dick Morley is considered as the father of PLC as he had invented the first PLC, the Modicon 084, for General Motors in 1968. PLCs can range from small modular devices with tens of inputs and outputs (I/O), in a housing integral with the processor, to large rack-mounted modular devices with thousands of I/O, and which are often networked to other PLC and SCADA systems. They can be designed for many arrangements of digital and analog I/O, extended temperature ranges, immunity to electrical noise, and resistance to vibration and impact. Programs to control machine operation are typically stored in battery-backed-up or non-volatile memory. PLCs were first devel ...

Sheave
A sheave () or pulley wheel is a grooved wheel often used for holding a belt, wire rope, or rope and incorporated into a pulley. The sheave spins on an axle or bearing inside the frame of the pulley. This allows the wire or rope to move freely, minimizing friction and wear on the cable. Sheaves can be used to redirect a cable or rope, lift loads, and transmit power. The words ''sheave'' and ''pulley'' are sometimes used interchangeably. Adjustable pulley A sheave can also refer to a pulley which has an adjustable operating diameter for use with a mechanical belt. This is accomplished by constructing the pulley out of several pieces. The two main "halves" of the pulley can be moved closer together or farther apart, thus altering the operational diameter. The usual construction is some sort of locking collar or set screws to secure the components, one half with a threaded central shaft and one half with a threaded center. By rotating the components, one can "screw" the parts ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Steel
Steel is an alloy made up of iron with added carbon to improve its strength and fracture resistance compared to other forms of iron. Many other elements may be present or added. Stainless steels that are corrosion- and oxidation-resistant typically need an additional 11% chromium. Because of its high tensile strength and low cost, steel is used in buildings, infrastructure, tools, ships, trains, cars, machines, electrical appliances, weapons, and rockets. Iron is the base metal of steel. Depending on the temperature, it can take two crystalline forms (allotropic forms): body-centred cubic and face-centred cubic. The interaction of the allotropes of iron with the alloying elements, primarily carbon, gives steel and cast iron their range of unique properties. In pure iron, the crystal structure has relatively little resistance to the iron atoms slipping past one another, and so pure iron is quite ductile, or soft and easily formed. In steel, small amounts of carbon, other ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aluminium
Aluminium (aluminum in American and Canadian English) is a chemical element with the symbol Al and atomic number 13. Aluminium has a density lower than those of other common metals, at approximately one third that of steel. It has a great affinity towards oxygen, and forms a protective layer of oxide on the surface when exposed to air. Aluminium visually resembles silver, both in its color and in its great ability to reflect light. It is soft, non-magnetic and ductile. It has one stable isotope, 27Al; this isotope is very common, making aluminium the twelfth most common element in the Universe. The radioactivity of 26Al is used in radiodating. Chemically, aluminium is a post-transition metal in the boron group; as is common for the group, aluminium forms compounds primarily in the +3 oxidation state. The aluminium cation Al3+ is small and highly charged; as such, it is polarizing, and bonds aluminium forms tend towards covalency. The strong affinity tow ...

Blue Plaque
A blue plaque is a permanent sign installed in a public place in the United Kingdom and elsewhere to commemorate a link between that location and a famous person, event, or former building on the site, serving as a historical marker. The term is used in the United Kingdom in two different senses. It may be used narrowly and specifically to refer to the "official" scheme administered by English Heritage, and currently restricted to sites within Greater London; or it may be used less formally to encompass a number of similar schemes administered by organisations throughout the UK. The plaques erected are made in a variety of designs, shapes, materials and colours: some are blue, others are not. However, the term "blue plaque" is often used informally to encompass all such schemes. The "official" scheme traces its origins to that launched in 1866 in London, on the initiative of the politician William Ewart, to mark the homes and workplaces of famous people. It has been administe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Concrete
Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time. Concrete is the second-most-used substance in the world after water, and is the most widely used building material. Its usage worldwide, ton for ton, is twice that of steel, wood, plastics, and aluminum combined. Globally, the ready-mix concrete industry, the largest segment of the concrete market, is projected to exceed $600 billion in revenue by 2025. This widespread use results in a number of environmental impacts. Most notably, the production process for cement produces large volumes of greenhouse gas emissions, leading to net 8% of global emissions. Other environmental concerns include widespread illegal sand mining, impacts on the surrounding environment such as increased surface runoff or urban heat island effect, and potential public health implications from toxic ingredients. Significant research and development is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hudswell Clarke
Hudswell, Clarke and Company Limited was an engineering and locomotive building company in Jack Lane, Hunslet, Leeds, West Yorkshire, England. History The company was founded as Hudswell and Clarke in 1860. In 1870 the name was changed to Hudswell, Clarke and Rodgers. There was another change in 1881 to Hudswell, Clarke and Company. The firm became a limited company in 1899. In 1862, soon after the company had been formed, they were given the initial design work on William Hamond Bartholomew's compartment boats for the Aire and Calder Navigation. The choice of the company may have been influenced by the fact that Bartholomew, the chief engineer for the Navigation, and William Clayton, one of the founders of Hudswell and Clarke, both lived on Spencer Place in Leeds. They produced at least one of the prototype Tom Pudding compartments, but did not get the main contract for their production once the design work had been done. As steam locomotive builders, like many of the sm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
