The art of woodworking was cultivated, and at least one illustrated manuscript dates to this period. Caravanserais dotted the major trade routes across the region, placed at intervals of a day's travel. The construction of these caravanserai inns improved in scale, fortification, and replicability. Also, they began to contain central mosques.

Between 1955 and 1956, cable was laid between Gallanach Bay, near Oban, Scotland and Clarenville, Newfoundland and Labrador. It was inaugurated on September 25, 1956, initially carrying 36 telephone channels. In the 1960s, transoceanic cables were coaxial cables that transmitted frequency-multiplexed voiceband signals. A high-voltage direct current on the inner conductor powered repeaters (two-way amplifiers placed at intervals along the cable).

Besides its function as a grain shipment route and major vein of river-borne indigenous trade in China, the Grand Canal had long been a government-operated courier route as well. In the Ming dynasty, official courier stations were placed at intervals of . Each courier station was assigned a different name, all of which were popularized in travel songs of the period.Brook, 48–49.

These sealed, unpowered transponders were placed at intervals of no more than 1 km. Approaching speed restrictions were provided at the appropriate distance, along with an audible alert; failure to acknowledge these alerts would result in an automatic brake application. C-APT was driven by a redundant onboard computer system using Intel 4004 microprocessors. The track units were essentially the same as the modern French Balise beacons.

A number of these cylinders could be transported on the back of a vehicle and, at a weight of just under , could be deployed reasonably quickly wherever an ambush was required. The cylinders would be placed at intervals along a road each with a short length of hose leading to a nozzle secured by ground spikes. Flow was initiated by a pull-string that opened a valve and ignition was provided by Molotov cocktails.

In the case of the UK AA, these were traditionally motorcycle-mounted prior to the introduction of vans. When communication technology and availability made it practical, a network of emergency phone boxes, placed at intervals by the roadside, was introduced in some countries. In recent years, the widespread ownership of mobile phones has, to a large degree, supplanted the need for an emergency phone network. Mobile technology has led to the development of free applications (apps).

The edges would be done in pearls of varying sizes in up to three rows. There were occasionally drop pearls placed at intervals to add to the richness. The collar came over the collarbone to cover a portion of the upper chest. The Imperial Regalia of the Holy Roman Emperors, kept in the Schatzkammer (Vienna), contains a full set of outer garments made in the 12th century in essentially Byzantine style at the Byzantine-founded workshops in Palermo.

The 2nd Battalion's APCs were placed at intervals around the base perimeter. The areas between the APCs were protected by foxholes manned by infantry, engineers, and artillerymen. Just after sunset, the troops on the perimeter fired their weapons to test their readiness and put on a show of force to any VC in the vicinity. Ambush patrols and listening posts left the perimeter of the base for their sentry positions in the surrounding jungle for the night.

By ordering the solids selectively—octahedron, icosahedron, dodecahedron, tetrahedron, cube—Kepler found that the spheres could be placed at intervals corresponding to the relative sizes of each planet's path, assuming the planets circle the Sun. Kepler also found a formula relating the size of each planet's orb to the length of its orbital period: from inner to outer planets, the ratio of increase in orbital period is twice the difference in orb radius. However, Kepler later rejected this formula, because it was not precise enough.Caspar. Kepler, pp.

Watson was Professor of Physics at the University of Leeds from 1984, having previously been Reader in Particle Cosmic Physics there, and retired in 2003 with the title Emeritus Professor. Watson was instrumental in the creation of the Pierre Auger Observatory in Argentina (begun 1999) which gathered the data that led to major discoveries in cosmic-ray astronomy. The Observatory covers an area of 3000 square km with 1,600 particle detectors each placed at intervals. Watson was serving as the spokesperson of the Pierre Auger collaboration and was later given the title of Spokesperson Emeritus.

Potatoes would be placed at intervals along each lane, and a basket would be placed several feet behind the lane. Runners would race to retrieve potatoes one by one, returning each one to the basket before returning for the next. The winner was the first to collect all the potatoes in their lane. In one variation, two runners competed to be the first to return fifty potatoes to their own basket, racing simultaneously to take the closest potato from a single line of one hundred potatoes rather than separate lanes.

The track crosses mountain areas, rocky ground, hills and valleys; tarmac is avoided as much as possible. The length varies between 100 km and 180 km each day depending on the class that the competitor enters. The main challenges are the technical parts, which lead through wooded areas, where competitors are challenged with natural terrain obstacles, they traverse over trees, rocks, mud, and mountains. Petrol fuel stops, or tank stops, are placed at intervals of approximately 70 km, where contestants refuel their motorcycles and have the opportunity to refresh themselves.

Its near perfect shape and the discovery of a posthole in the very centre of the enclosure, indicates that the circle was measured out from a central stake with a rope. Twelve large orthostats have been placed at intervals around the stone ring, each standing directly opposite one of the other 'axial' stones. The stones are contiguous rather than free-standing, and the surrounding bank makes it look more like a form of henge monument than a conventional stone circle. This embankment and the precise arrangement of orthostats suggest that this site had a ritual purpose.

74-75), Until December 1917, only two U-boats had been destroyed by the barrage. Furthermore, the patrolling vessels were vulnerable to attack by German torpedo boats,Lawrence Sondhaus, World War One: The Global Revolution, Cambridge University Press 2011 (p.287), as in the action of 26–27 October 1916, and the action of 20 April 1917. The Engineer-in-Chief to the Admiralty, Sir Alexander Gibb, devised a scheme of eight or twelve large concrete and steel towers, placed at intervals on the sea bed across the Dover Strait from Folkestone to Cap Gris Nez.

Placed at intervals along the shafts were pulleys with belts that powered the gang saw, the haul-up, the trimmer, the edger, and the planer. A small building beside the mill, called the powerhouse, housed a dynamo, a rotating machine that produced direct current electricity to provide light for the settlement's buildings, 20 years before Weymouth was first supplied with electric power in 1926. The forests of Digby County were diverse and rich in hardwoods. The mill at New France exported maple, oak, beech and birch lumber for sale for flooring and doors, as well as red spruce and balsam fir for framing, and white pine for ships' masts.

Wind flags are placed on the range between the shooter and the target, and allow a skilled shooter to judge the amount of correction that needs to be made to place each shot precisely on the target. Flags can be home builtQuick and Easy Wind Flag or purchased. They generally consist of a wind vane to indicate wind direction, and a cloth (or plastic) streamer and/or propeller to indicate wind speed (the higher the wind, the greater the angle of the streamer or speed of the propeller). Multiple flags are usually used, and they are placed at intervals along the path of the bullet from rifle to target.

Part of the Kerlescan alignment in Carnac, Brittany Stone rows can be few metres or several kilometres in length and made from stones that can be as tall as 2m, although 1m high stones are more common. The terminals of many rows have the largest stones and other megalithic features are sometimes sited at the ends, especially burial cairns. The stones are placed at intervals and may vary in height along the sequence, to provide a graduated appearance, though it is not known whether this was done deliberately. Stone rows were erected by the later Neolithic and Bronze Age peoples in the British Isles, parts of Scandinavia and northern France.

Also on that day, the power for the police to apply advisory speed limits of to motorways affected by bad weather was also introduced. The advisory limit was activated by the use of flashing amber lights placed at intervals along the motorways. In April 1966 Barbara Castle, the new Minister of Transport, decided to extend the experimental limit for a further two months to allow the Road Research Laboratory (RRL) time to collect data as there was still no conclusive evidence of its effectiveness. In May 1966 Barbara Castle extended the experimental period by a further fifteen months to 3 September 1967 as "the case is not proven" but there were signs of crash rate reduction.

A typical tower identification tag The International Civil Aviation Organization issues recommendations on markers for towers and the conductors suspended between them. Certain jurisdictions will make these recommendations mandatory, for example that certain power lines must have overhead wire markers placed at intervals, and that warning lights be placed on any sufficiently high towers, this is particularly true of transmission towers which are in close vicinity to airports. Electricity pylons often have an identification tag marked with the name of the line (either the terminal points of the line or the internal designation of the power company) and the tower number. This makes identifying the location of a fault to the power company that owns the tower easier.

A Prussian milestone c. 1836, reading "II MEILEN BIS BERLIN" ("two miles to Berlin"). The first direction signs were milestones on the Roman road network; finding one's location on the long, straight roads was difficult, and hence, large stones were placed at intervals along the roads, giving the distance in Roman miles to nearby major cities, and usually to the capitals of major provinces. As most Roman roads diverged from Rome, one of the numbers was usually the distance to the Milliarium Aureum, a large golden milestone in the centre of Rome, although sometimes other stones, such as the London Stone, were used in places where measuring distances from Rome was impossible or not useful.

The more moderate climate meant that the winter snow roads could not be used and instead necessitated the use of log skid roads. Trees were so tall that springboards were wedged into notches cut into the trunk to serve as work platforms for two loggers using heavy double bit steel axes. Human and animal muscle, powered the industry until 1897 when the steam- powered "donkey engine" was introduced in B.C. from the US. This stationary machine drove a winch connected to a rope or wire which was used to haul logs up to 150 metres across the forest floor. A series of such engines placed at intervals could be used to haul large numbers of logs, long distances in relatively short periods of time.

Reconstruction of a Roman courtyard fountain in Pompeii (1st century AD) The Ancient Romans built an extensive system of aqueducts from mountain rivers and lakes to provide water for the fountains and baths of Rome. The Roman engineers used lead pipes instead of bronze to distribute the water throughout the city. The excavations at Pompeii, which revealed the city as it was when it was destroyed by Mount Vesuvius in 79 AD, uncovered free-standing fountains and basins placed at intervals along city streets, fed by siphoning water upwards from lead pipes under the street. The excavations of Pompeii also showed that the homes of wealthy Romans often had a small fountain in the atrium, or interior courtyard, with water coming from the city water supply and spouting into a small bowl or basin.

By the end of that month the tunnellers successfully demonstrated "surprise" anti-tank obstacles near Shornmead Fort, Chatham. The drills and pipe pushing machines were used to bury a series of diameter pipes, each at a shallow angle to a maximum depth of about . Each pipe was about long and they were placed at intervals of in an overlapping pattern such that the lower end of the first pipe would end up about 15 feet underground; the next pipe would then be pushed into the ground behind the first so that the upper end of that pipe would overlap with the lower end of the earlier pipe. The pipes were packed with explosives which when detonated would produce a very effective anti-tank obstacle about wide and deep with loose soil at the bottom.

The remains of Milecastle 39 (Castle Nick), near Steel Rigg on Hadrian's Wall. A milecastle was a small fort (fortlet), a rectangular fortification built during the period of the Roman Empire. They were placed at intervals of approximately one Roman mile along several major frontiers, for example Hadrian's Wall in Great Britain (Britannia in the Roman period), hence the name. Along Hadrian's Wall, milecastles were initially constructed of stone in the eastern two thirds, and stacked turf with a wooden palisade in the western third, though the turf milecastles were later rebuilt in stone. Size varied, but in general they were about 15m by 18m (16 by 20 yards) internally, with stone walls as much as 3m (10 feet) thick and probably 5m to 6m (17 to 20 feet) high, to match the height of the adjacent wall.
