Ebro
The Ebro (Spanish and Basque ; , , ) is a river of the north and northeast of the Iberian Peninsula, in Spain. It rises in Cantabria and flows , almost entirely in an east-southeast direction. It flows into the Mediterranean Sea, forming a delta in the Terres de l'Ebre region, in southern Catalonia. In the Iberian peninsula, it ranks second in length after the Tagus and second in discharge volume, and drainage basin, after the Douro. It is the longest river entirely within Spain; the other two mentioned flow into Portugal. The Ebro flows through many cities (): Reinosa in Cantabria; Frías and Miranda de Ebro in Castile and León; Haro, Logroño, Calahorra, and Alfaro in La Rioja; Tudela in Navarre; Alagón, Utebo, and Zaragoza in Aragon; and Flix, Móra d'Ebre, Benifallet, Tivenys, Xerta, Aldover, Tortosa, and Amposta in the province of Tarragona (Catalonia).

Workman, Clark And Company
Workman, Clark and Company, also known as Workman & Clark, was a shipbuilding company based in Belfast. It operated from 1879 until it went out of business in 1935. History The business was established by Frank Workman and George Clark in Belfast Harbour in 1879 and incorporated as Workman, Clark and Company Limited in 1880. Both founders had family connections in the shipbuilding industry and had previously worked for Harland & Wolff. By 1895 it was the fourth largest shipbuilder in the United Kingdom of Great Britain and Ireland and by 1900 it was building transatlantic liners for major customers such as Cunard Line and Alfred Holt. It expanded further to meet demand during the First World War and was acquired by the Northumberland Shipbuilding Company in 1918. Both founders retired from the board in 1921 after various problems at the company. Northumberland Shipbuilding went into receivership in 1927. Workman, Clark and Company was then temporarily resurrected, only to go i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Submarine Signals
Submarine signals had a specific, even proprietary, meaning in the early 20th century. It applied to a Navigational aid, navigation aid system developed, patented and produced by the Submarine Signal Company of Boston. The company produced submarine acoustic signals, first bells and receivers then transducers, as aids to navigation. The signals were fixed, associated with lights and other fixed aids, or installed aboard ships enabling warning of fixed hazards or signaling between ships. Atlas Werke, ATLAS-Werke, at the time Norddeutsche Maschinen und Armaturenfabrik, of Germany also manufactured the equipment under license largely for the European market. The system used more reliable underwater sound to project acoustic signals from a Signal station, shore station or an undersea hazard on which a signal was placed. The signals were usually associated with a lightvessel, a bell buoy or hung on a tripod frame on the sea floor connected to a shore stations by cable. At first the sy ...

Depth Charge
A depth charge is an anti-submarine warfare (ASW) weapon designed to destroy submarine A submarine (often shortened to sub) is a watercraft capable of independent operation underwater. (It differs from a submersible, which has more limited underwater capability.) The term "submarine" is also sometimes used historically or infor ...s by detonating in the water near the target and subjecting it to a destructive shock factor, hydraulic shock. Most depth charges use high explosives with a fuze set to detonate the charge, typically at a specific depth from the surface. Depth charges can be dropped by ships (typically fast, agile surface combatants such as destroyers or frigates), patrol aircraft and helicopters. Depth charges were developed during World War I, and were one of the first viable methods of attacking a submarine underwater. They were widely used in World War I and World War II, and remained part of the anti-submarine arsenals of many navies during the Cold War, duri ...

QF 6-pounder Hotchkiss
The Ordnance QF Hotchkiss 6 pounder gun Mk I and Mk II or QF 6 pounder 8 cwt were a family of long-lived light naval guns introduced in 1885 to defend against new, small and fast vessels such as torpedo boats and later submarines. Many variants were produced, often under license, which ranged in length from 40 to 58 calibres, with 40 calibre the most common. 6-pounders were widely used by the navies of a number of nations and often used by both sides in a conflict. Due to advances in torpedo delivery and performance, 6-pounder guns were rapidly made obsolete and were replaced with larger guns aboard most larger warships. This led to their being used ashore during World War I as coastal defence guns, the first tank guns and as anti-aircraft guns, whether on improvised or specialized HA/LA mounts. During World War II 6-pounder guns were put back in service to arm small warships and as coastal defence guns. The last ships to carry 6-pounders were the Aegir-class offshore pa ...

QF 6-inch Naval Gun
The QF 6-inch 40 calibre naval gun (Quick firing gun, Quick-Firing) was used by many United Kingdom-built warships around the end of the 19th century and the start of the 20th century. In British service it was known as the QF 6-inch Mk I, II, III guns.Mk I, II and III = Marks 1, 2 and 3. Britain used Roman numerals to denote Marks (models) of service ordnance until after the Second World War. This article describes the first three models of Royal Navy 6-inch QF guns. As the 15 cm/40 (6") 41st Year Type naval gun it was used for pre-dreadnought battleships, armoured cruisers and protected cruisers of the early Imperial Japanese Navy built in UK and European shipyards. It was also the heaviest gun ever carried by a pre-Cold War destroyer. Design QF technology These guns were developed to exploit the new "British ordnance terms#QF, QF" technology, which involved loading the propellant charge in a brass case with integrated primer in its base. This allowed a faster rate of f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
