Mechelen-Zuid Water Tower
The Mechelen-Zuid water tower is a , combined water and telecommunications tower constructed in 1978. Since 1979, it has supplied the water to the city of Mechelen, Belgium, while also hosting television and telecommunications aerials. The concrete spire passes through a wide disc holding water fifty metres above the ground. Higher up, a smaller disc supports telecommunications equipment. Topped by a decorative stainless steel tube, it is claimed to be the highest water tower in the world. Planning, design, and construction This water tower was built to supply an increased demand for water due to the growth of the Mechelen population, and of industry around the city. In March 1977, the City commissioned a design for a water tower with telecom purposes from local engineering firm ITH, who contacted Professor Fernand Mortelmans ( University of Leuven),Mortelmans, F. (1980), "Water- en antennetoren te Mechelen.", page 109, quote : "Om het probleem van de drinkwatervoorziening van de s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mechelen
Mechelen (; french: Malines ; traditional English name: MechlinMechelen has been known in English as ''Mechlin'', from where the adjective ''Mechlinian'' is derived. This name may still be used, especially in a traditional or historical context. The city's French name ' had also been used in English in the past (in the 19th and 20th century) however this has largely been abandoned. Meanwhile, the Dutch derived ' began to be used in English increasingly from late 20th century onwards, even while ''Mechlin'' remained still in use (for example a ''Mechlinian'' is an inhabitant of this city or someone seen as born-and-raised there; the term is also the name of the city dialect; as an adjective ''Mechlinian'' may refer to the city or to its dialect.) is a city and municipality in the province of Antwerp in the Flemish Region of Belgium. The municipality comprises the city of Mechelen proper, some quarters at its outskirts, the hamlets of (adjacent) and (a few kilometers away), as ...

Water Tower
A water tower is an elevated structure supporting a water tank constructed at a height sufficient to pressurize a water distribution system, distribution system for potable water, and to provide emergency storage for fire protection. Water towers often operate in conjunction with underground or surface service reservoirs, which store treated water close to where it will be used. Other types of water towers may only store raw (non-potable) water for fire protection or industrial purposes, and may not necessarily be connected to a public water supply. Water towers are able to supply water even during power outages, because they rely on hydrostatic pressure produced by elevation of water (due to gravity) to push the water into domestic and industrial water distribution systems; however, they cannot supply the water for a long time without power, because a pump is typically required to refill the tower. A water tower also serves as a reservoir to help with water needs during peak us ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Belgian Franc
The Belgian franc ( nl, Belgische frank, french: Franc belge, german: Belgischer Franken) was the currency of the Kingdom of Belgium from 1832 until 2002 when the Euro was introduced. It was subdivided into 100 subunits, each known as a in Dutch, in French or a in German. History The ''gulden'' (guilder) of 20 ''stuivers'' was the currency of present-day Belgium from the 15th to 19th centuries until its replacement in 1832 by the Belgian franc. Its value differed from the Dutch guilder, gulden of the Dutch Republic during the latter's separation from Belgium from 1581 to 1816. Standard coins issued in Belgium include: * From 1618: the :nl:Patagon, ''patagon'' or ''Albertusthaler'' of 24.55 g fine silver, worth 2.4 gulden or 48 stuiver (or 10.23 g fine silver per gulden) * From 1754: the ''kronenthaler'' of 25.71 g fine silver, worth 3.15 gulden ''currency'' or 2.7 ''gulden of exchange'' (9.52 g silver per exchange gulden).

Aircraft Warning Lights
Aviation obstruction lighting is used to enhance the visibility of structures or fixed obstacles which may conflict with the safe navigation of aircraft. Obstruction lighting is commonly installed on towers, buildings, and even fences located in areas where aircraft may be operating at low altitudes. In certain areas, some List of aviation regulatory bodies, aviation regulators mandate the installation, operation, color, and/or NOTAM, status notification of obstruction lighting. For maximum visibility and collision-avoidance, these lighting systems commonly employ one or more high-intensity Strobe light, strobe or LED lamp, LED devices which can be seen by Aircraft pilot, pilots from many miles away from the obstruction. Lamp types The lights generally come in two forms: * Red lamps that are either constantly illuminated or turn on and off slowly in a cycle of a few seconds. * White xenon flash lamps. Both types were in use in the United Kingdom until recently. New r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lightning Rod
A lightning rod or lightning conductor (British English) is a metal rod mounted on a structure and intended to protect the structure from a lightning strike. If lightning hits the structure, it will preferentially strike the rod and be conducted to ground through a wire, instead of passing through the structure, where it could start a fire or cause electrocution. Lightning rods are also called finials, air terminals, or strike termination devices. In a lightning protection system, a lightning rod is a single component of the system. The lightning rod requires a connection to earth to perform its protective function. Lightning rods come in many different forms, including hollow, solid, pointed, rounded, flat strips, or even bristle brush-like. The main attribute common to all lightning rods is that they are all made of conductive materials, such as copper and aluminum. Copper and its alloys are the most common materials used in lightning protection. History The principle of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Slip Forming
Slip forming, continuous poured, continuously formed, or slipform construction is a construction method in which concrete is poured into a continuously moving form.Nawy, ''Concrete Construction Engineering Handbook,'' 2008, p. 10—33. Slip forming is used for tall structures (such as bridges, towers, buildings, and dams), as well as horizontal structures, such as roadways. Slipforming enables continuous, non-interrupted, cast-in-place "flawless" (i.e. no joints) concrete structures which have superior performance characteristics to piecewise construction using discrete form elements. Slip forming relies on the quick-setting properties of concrete, and requires a balance between quick-setting capacity and workability. Concrete needs to be workable enough to be placed into the form and consolidated (via vibration), yet quick-setting enough to emerge from the form with strength. This strength is needed because the freshly set concrete must not only permit the form to "slip" by the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Circular Sector
A circular sector, also known as circle sector or disk sector (symbol: ⌔), is the portion of a disk (a closed region bounded by a circle) enclosed by two radii and an arc, where the smaller area is known as the ''minor sector'' and the larger being the ''major sector''. In the diagram, is the central angle, r the radius of the circle, and L is the arc length of the minor sector. The angle formed by connecting the endpoints of the arc to any point on the circumference that is not in the sector is equal to half the central angle. Types A sector with the central angle of 180° is called a '' half-disk'' and is bounded by a diameter and a semicircle. Sectors with other central angles are sometimes given special names, such as quadrants (90°), sextants (60°), and octants (45°), which come from the sector being one 4th, 6th or 8th part of a full circle, respectively. Confusingly, the arc of a quadrant (a circular arc) can also be termed a quadrant. Compass Traditionally wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parabolic Antenna
A parabolic antenna is an antenna that uses a parabolic reflector, a curved surface with the cross-sectional shape of a parabola, to direct the radio waves. The most common form is shaped like a dish and is popularly called a dish antenna or parabolic dish. The main advantage of a parabolic antenna is that it has high directivity. It functions similarly to a searchlight or flashlight reflector to direct radio waves in a narrow beam, or receive radio waves from one particular direction only. Parabolic antennas have some of the highest gains, meaning that they can produce the narrowest beamwidths, of any antenna type. In order to achieve narrow beamwidths, the parabolic reflector must be much larger than the wavelength of the radio waves used, so parabolic antennas are used in the high frequency part of the radio spectrum, at UHF and microwave ( SHF) frequencies, at which the wavelengths are small enough that conveniently-sized reflectors can be used. Parabolic antennas are u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radio Masts And Towers
Radio masts and towers are typically tall structures designed to support antennas for telecommunications and broadcasting, including television. There are two main types: guyed and self-supporting structures. They are among the tallest human-made structures. Masts are often named after the broadcasting organizations that originally built them or currently use them. In the case of a mast radiator or radiating tower, the whole mast or tower is itself the transmitting antenna. Terminology The terms "mast" and "tower" are often used interchangeably. However, in structural engineering terms, a tower is a self-supporting or cantilevered structure, while a mast is held up by stays or guys. Broadcast engineers in the UK use the same terminology. A mast is a ground-based or rooftop structure that supports antennas at a height where they can satisfactorily send or receive radio waves. Typical masts are of steel lattice or tubular steel construction. Masts themselves play no part in t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Towers Completed In 1978
A tower is a tall structure, taller than it is wide, often by a significant factor. Towers are distinguished from masts by their lack of guy-wires and are therefore, along with tall buildings, self-supporting structures. Towers are specifically distinguished from buildings in that they are built not to be habitable but to serve other functions using the height of the tower. For example, the height of a clock tower improves the visibility of the clock, and the height of a tower in a fortified building such as a castle increases the visibility of the surroundings for defensive purposes. Towers may also be built for observation, leisure, or telecommunication purposes. A tower can stand alone or be supported by adjacent buildings, or it may be a feature on top of a larger structure or building. Etymology Old English ''torr'' is from Latin ''turris'' via Old French ''tor''. The Latin term together with Greek τύρσις was loaned from a pre-Indo-European Mediterranean langua ...
