Wells Light
A Wells light was a large paraffin-fuelled (kerosene) blowlamp used for engineering work, particularly for illumination, in Victorian times. At a time before widespread electrical lighting, they were the most common form of high-powered portable illumination used for construction work, particularly railways, civil engineering, shipyards and ironworks. Operation The Wells light was a typical blowlamp in principle, consisting of a floor-standing fuel tank with the burner on a tall post above it. It was distinguished by its large size, the more common plumber's blow lamp being a hand-held tool of about a pint in capacity. Wells lights were made in a number of sizes, the smallest Nº1 being of 800 candlepower with a 15 inch flame. Weighing when filled, it was advertised as "can be carried by a boy". The largest Nº3 produced 2,000 candlepower, weighed 240 lbs, and was available with barrow wheels for portability. The burner of the Wells light used a vaporiser that hea ...

Brazier
A brazier () is a container used to burn charcoal or other solid fuel for cooking, heating or cultural rituals. It often takes the form of a metal box or bowl with feet. Its elevation helps circulate air, feeding oxygen to the fire. Braziers have been used since ancient times; the Nimrud brazier dates to at least 824 BC. History The word brazier is mentioned in the Bible. The Hebrew word for brazier is believed to be of Egyptian origin, suggesting that it was imported from Egypt. The lone reference to it in the Bible being the following verse: * - the winter palace of King Jehoiakim was heated by a brazier (). Roman Emperor Jovian was poisoned by the fumes from a brazier in his tent in 364, ending the line of Constantine. Uses Heating Despite risks in burning charcoal on open fires, braziers were widely adopted for domestic heating, particularly and somewhat more safely used (namely in unglazed, shuttered-only buildings) in the Spanish-speaking world.

Licence-built
Licensed production is the production under license of technology developed elsewhere. The licensee provides the licensor of a specific product with legal production rights, technical information, process technology, and any other proprietary components that cannot be sourced by the licensor. This is an especially prominent commercial practice in developing nations, which often approach licensed production as a starting point for indigenous industrial development. While licensed production in developing nations provides stimulus to the production and technical capabilities of local industry, in many cases it remains at least partly dependent on foreign support. History The four most common applications of licensed production have historically been automotive engines and parts, weaponry, aircraft, and pharmaceuticals. During World War I, it was more common for licensing agreements to take place between companies in the same country; for example, Opel was granted a license to p ...

Genericized
A generic trademark, also known as a genericized trademark or proprietary eponym, is a trademark or brand name that, because of its popularity or significance, has become the generic term for, or synonymous with, a general class of products or services, usually against the intentions of the trademark's owner. A trademark is said to become ''genericized''—or, informally, to have suffered ''genericide''—when it begins as a distinctive product identifier but changes in meaning to become generic. This typically happens when the products or services which the trademark is associated with have acquired substantial market dominance or mind share, such that the primary meaning of the genericized trademark becomes the product or service itself rather than an indication of source for the product or service. A trademark thus popularised has its legal protection at risk in some countries such as the United States and United Kingdom, as its intellectual property rights in the trademark ...

Hither Green Railway Station
Hither Green is a railway station located in Hither Green in the London Borough of Lewisham, south-east London. It is down the line from and is situated between and either or depending on the route. It is a busy commuter station with services to several London termini (Cannon Street, Charing Cross and London Bridge) and destinations to other parts of south-east London and the south-east of England (Orpington and Sevenoaks on the South Eastern Main Line, and Dartford and Gravesend on the Dartford Loop Line). It is in Travelcard Zone 3 and very close to Hither Green Traction Maintenance Depot (TMD), Grove Park Traction and Rolling Stock Maintenance Depot, and Grove Park Safety Training Centre.

Flashlight
A flashlight ( US, Canada) or torch ( UK, Australia) is a portable hand-held electric lamp. Formerly, the light source typically was a miniature incandescent light bulb, but these have been displaced by light-emitting diodes (LEDs) since the mid-2000s. A typical flashlight consists of the light source mounted in a reflector, a transparent cover (sometimes combined with a lens) to protect the light source and reflector, a battery, and a switch, all enclosed in a case. The invention of the dry cell and miniature incandescent electric lamps made the first battery-powered flashlights possible around 1899. Today, flashlights use mostly light-emitting diodes and run on disposable or rechargeable batteries. Some are powered by the user turning a crank, shaking the lamp, or squeezing it. Some have solar panels to recharge the battery. Flashlights are used as a light source outdoors, in places without permanently installed lighting, during power outages, or when a portable light sourc ...

Oil Lamp
An oil lamp is a lamp used to produce light continuously for a period of time using an oil-based fuel source. The use of oil lamps began thousands of years ago and continues to this day, although their use is less common in modern times. They work in the same way as a candle but with fuel that is liquid at room temperature, so that a container for the oil is required. A textile wick drops down into the oil, and is lit at the end, burning the oil as it is drawn up the wick. Oil lamps are a form of lighting, and were used as an alternative to candles before the use of electric lights. Starting in 1780, the Argand lamp quickly replaced other oil lamps still in their basic ancient form. These in turn were replaced by the kerosene lamp in about 1850. In small towns and rural areas the latter continued in use well into the 20th century, until such areas were finally electrified and light bulbs could be used. Sources of fuel for oil lamps include a wide variety of plants such as n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cast-iron
Cast iron is a class of iron–carbon alloys with a carbon content more than 2%. Its usefulness derives from its relatively low melting temperature. The alloy constituents affect its color when fractured: white cast iron has carbide impurities which allow cracks to pass straight through, grey cast iron has graphite flakes which deflect a passing crack and initiate countless new cracks as the material breaks, and ductile cast iron has spherical graphite "nodules" which stop the crack from further progressing. Carbon (C), ranging from 1.8 to 4 wt%, and silicon (Si), 1–3 wt%, are the main alloying elements of cast iron. Iron alloys with lower carbon content are known as steel. Cast iron tends to be brittle, except for malleable cast irons. With its relatively low melting point, good fluidity, castability, excellent machinability, resistance to deformation and wear resistance, cast irons have become an engineering material with a wide range of applications and are ...

Model Engineer
''Model Engineer Magazine'' was first published (in the United Kingdom) to support the hobby of model engineering in 1898 by Percival Marshall, who was to remain its editor for over 50 years. It has been owned by MyTime Media since 2008. The magazine addressed the emergence of a new hobby — the construction of models (often working) and experimental engineering, largely in metal. It transcended class barriers, appealing to professional engineers, jobbing machinists and anyone interested in making working mechanisms. Contributors The magazine has had many notable contributors, but foremost among these was LBSC ( pen name of Lillian 'Curly' Lawrence). From the inter-war period to the 1960s he produced many designs for simple but reliable small model steam locomotives. Most of these were published in ''Model Engineer'', and brought the construction of small passenger hauling locomotives within the reach of the typical home machinist. Other notable contributors include Henry Green ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
