Aspidistra (transmitter)
Aspidistra was a British medium wave radio transmitter used for black propaganda and military deception purposes against Nazi Germany during World War II. At times in its history it was the most powerful broadcast transmitter in the world. Its name – after the popular foliage houseplant – was inspired by the 1938 comic song " The Biggest Aspidistra in the World", best known as sung by Gracie Fields. The transmitter was installed in 1942 at a purpose-built site near Crowborough on Ashdown Forest in southeast England. This was equipped with other medium wave and short wave transmitters, which also used the Aspidistra name, being known as ASPI 2, ASPI 3, ASPI 4, etc. However, when the name ''Aspidistra'' was used on its own it always referred to the original medium wave transmitter (ASPI 1). The Crowborough station was run during the war by the British government's Political Warfare Executive (PWE). After the war, the station was run by the Diplomatic Wireless Service (DWS) ...

Diplomatic Wireless Service
The Diplomatic Wireless Service (DWS) was the name of the communications system set up for the British Foreign Office by Brigadier Richard Gambier-Parry, the first Foreign Office Director of Communications, in the latter part of 1945. It grew out of the Special Communication Units (SCU) which were responsible for communications for MI6 during the war. Its original base was at Whaddon Hall in Buckinghamshire, but it moved to Hanslope Park in the winter of 1946/47. The primary role of the DWS was communications between British embassies and the UK, this part of its operations being based at Hanslope Park, which is still the HQ of its successor, Her Majesty's Government Communications Centre (HMGCC). It also operated and maintained transmitters at home and abroad on behalf of the Foreign Office for the broadcasting of the European Service of the BBC and the BBC Overseas Service, which were combined as the BBC World Service in 1988. The main UK broadcast operation was based under ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Goliath Transmitter
Goliath transmitter was a very low frequency (VLF) transmitter for communicating with submarines, built by Nazi Germany's ''Kriegsmarine'' navy near Kalbe an der Milde in Saxony-Anhalt, Germany, which was in service from 1943 to 1945. It was capable of transmission power of between 100 and 1000 kW and was the most powerful transmitter of its time. History Submarines are shielded by conducting seawater from ordinary radio communication frequencies, but radio waves in the very low frequency (VLF) band from 3 to 30 kHz can penetrate seawater to depths of about 50 feet, allowing submarines to receive communications without surfacing and becoming vulnerable to detection. From 1943 to the end of World War II, Goliath was the main radio transmitter for German submarine radio communications, operating on frequencies between 15 and 25 kHz with a main working frequency of 16.55 kHz. Transmitting up to 1000 kilowatts of power, Goliath's transmissions could be receiv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kingston Upon Hull
Kingston upon Hull, usually abbreviated to Hull, is a port city and unitary authority in the East Riding of Yorkshire, England. It lies upon the River Hull at its confluence with the Humber Estuary, inland from the North Sea and south-east of York, the historic county town. With a population of (), it is the fourth-largest city in the Yorkshire and the Humber region after Leeds, Sheffield and Bradford. The town of Wyke on Hull was founded late in the 12th century by the monks of Meaux Abbey as a port from which to export their wool. Renamed ''Kings-town upon Hull'' in 1299, Hull had been a market town, military supply port, trading centre, fishing and whaling centre and industrial metropolis.

Longwave
In radio, longwave, long wave or long-wave, and commonly abbreviated LW, refers to parts of the radio spectrum with wavelengths longer than what was originally called the medium-wave broadcasting band. The term is historic, dating from the early 20th century, when the radio spectrum was considered to consist of longwave (LW), medium-wave (MW), and short-wave (SW) radio bands. Most modern radio systems and devices use wavelengths which would then have been considered 'ultra-short'. In contemporary usage, the term ''longwave'' is not defined precisely, and its intended meaning varies. It may be used for radio wavelengths longer than 1,000 m i.e. frequencies up to 300 kilohertz (kHz), including the International Telecommunication Union's (ITU's) low frequency (LF, 30–300 kHz) and very low frequency (VLF, 3–30 kHz) bands. Sometimes the upper limit is taken to be higher than 300 kHz, but not above the start of the medium wave broadcast band at 520&nb ...

East Sussex
East Sussex is a ceremonial and non-metropolitan county in South East England on the English Channel coast. It is bordered by Kent to the north and east, West Sussex to the west, and Surrey to the north-west. The largest settlement in East Sussex is the city of Brighton and Hove. History East Sussex is part of the historic county of Sussex, which has its roots in the ancient kingdom of the South Saxons, who established themselves there in the 5th century AD, after the departure of the Romans. Archaeological remains are plentiful, especially in the upland areas. The area's position on the coast has also meant that there were many invaders, including the Romans and later the Normans. Earlier industries have included fishing, iron-making, and the wool trade, all of which have declined, or been lost completely. Governance Sussex was historically sub-divided into six rapes. From the 12th century the three eastern rapes together and the three western rapes together had separ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heavy Oil Engine
The Hornsby-Akroyd oil engine, named after its inventor Herbert Akroyd Stuart and the manufacturer Richard Hornsby & Sons, was the first successful design of an internal combustion engine using heavy oil as a fuel. It was the first to use a separate vapourising combustion chamber and is the forerunner of all hot-bulb engines, which are considered predecessors of the similar Diesel engine, developed a few years later. Early internal combustion engines were quite successful running on gaseous and light petroleum fuels. However, due to the dangerous nature of petroleum and light petroleum fuel, legal restrictions were placed on their transportation and storage. Heavier petroleum fuels, such as kerosene, were quite prevalent, as they were used for lighting, but posed specific problems when used in internal combustion engines: Oil used for engine fuel must be turned to a vapour state and remain in that state during compression. Furthermore, the combustion of the fuel must be powerf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crossley-Premier
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.

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 pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canada
Canada is a country in North America. Its ten provinces and three territories extend from the Atlantic Ocean to the Pacific Ocean and northward into the Arctic Ocean, covering over , making it the world's second-largest country by total area. Its southern and western border with the United States, stretching , is the world's longest binational land border. Canada's capital is Ottawa, and its three largest metropolitan areas are Toronto, Montreal, and Vancouver. Indigenous peoples have continuously inhabited what is now Canada for thousands of years. Beginning in the 16th century, British and French expeditions explored and later settled along the Atlantic coast. As a consequence of various armed conflicts, France ceded nearly all of its colonies in North America in 1763. In 1867, with the union of three British North American colonies through Confederation, Canada was formed as a federal dominion of four provinces. This began an accretion of provinces an ...
