SS Elisabethville (1921)
''Elisabethville'' was an ocean liner which was built in 1921 for Compagnie Belge Maritime du Congo. In 1930 the company became Compagnie Maritime Belge. She served the Antwerp - Matadi route, connecting Belgium to Belgian Congo. ''Elisabethville'' was named after a city in what was then Belgian Congo. The city is now Lubumbashi, which is the second largest city in the Democratic Republic of the Congo, only behind the capital Kinshasa. In 1940 ''Elisabethville'' was requisitioned by the Ministry of War Transport (MoWT) for use as a troopship. She briefly returned to merchant service in 1946 before being requisitioned again in 1947 for further troopship duties, and rechristened the ''Empire Bure''. She was then laid up before being sold in 1950 to Charlton Steamship Co. and was renamed ''Charlton Star''. In 1958 she was sold to Greek owners and renamed ''Maristrella'', serving until she was scrapped in 1960. Description ''Elisabethville'' was built by J Cockerill SA, Hoboken ...

Suez Crisis
The Suez Crisis, also known as the Second Arab–Israeli War, the Tripartite Aggression in the Arab world and the Sinai War in Israel, was a British–French–Israeli invasion of Egypt in 1956. Israel invaded on 29 October, having done so with the primary objective of re-opening the Straits of Tiran and the Gulf of Aqaba as the recent tightening of the eight-year-long Egyptian blockade further prevented Israeli passage. After issuing a joint ultimatum for a ceasefire, the United Kingdom and France joined the Israelis on 5 November, seeking to depose Egyptian president Gamal Abdel Nasser and regain control of the Suez Canal, which Nasser had earlier nationalised by transferring administrative control from the foreign-owned Suez Canal Company to Egypt's new government-owned Suez Canal Authority. Shortly after the invasion began, the three countries came under heavy political pressure from both the United States and the Soviet Union, as well as from the United Nations, even ...

Tugboat
A tugboat or tug is a marine vessel that manoeuvres other vessels by pushing or pulling them, with direct contact or a tow line. These boats typically tug ships in circumstances where they cannot or should not move under their own power, such as in crowded harbors or narrow canals, or cannot move at all, such as barges, disabled ships, log rafts, or oil platforms. Some are ocean-going, and some are icebreakers or salvage tugs. Early models were powered by steam engines, which were later superseded by diesel engines. Many have deluge gun water jets, which help in firefighting, especially in harbours. Types Seagoing Seagoing tugs (deep-sea tugs or ocean tugboats) fall into four basic categories: #The standard seagoing tug with model bow that tows almost exclusively by way of a wire cable. In some rare cases, such as some USN fleet tugs, a synthetic rope hawser may be used for the tow in the belief that the line can be pulled aboard a disabled ship by the crew owing t ...

Greenock
Greenock (; ; , ) is a town in Inverclyde, Scotland, located in the west central Lowlands of Scotland. The town is the administrative centre of Inverclyde Council. It is a former burgh within the historic county of Renfrewshire, and forms part of a contiguous urban area with Gourock to the west and Port Glasgow to the east. The 2011 UK Census showed that Greenock had a population of 44,248, a decrease from the 46,861 recorded in the 2001 UK Census. It lies on the south bank of the Clyde at the " Tail of the Bank" where the River Clyde deepens into the Firth of Clyde. History Name Place-name scholar William J. Watson wrote that "Greenock is well known in Gaelic as , dative of , 'a sunny knoll. The Scottish Gaelic place-name is relatively common, with another Greenock near Callander in Menteith (formerly in Perthshire) and yet another at Muirkirk in Kyle, now in East Ayrshire. R. M.

Holy Loch
The Holy Loch () is a sea loch, part of the Firth of Clyde, in Argyll and Bute, Scotland. The "Holy Loch" name is believed to date from the 6th century, when Saint Munn landed there after leaving Ireland. Kilmun Parish Church and Argyll Mausoleum is said to stand where Saint Munn's church was once located. Alexander Robertson & Sons, Robertson's Yard at Sandbank, Argyll and Bute, Sandbank, a village on the loch, was a major wooden boat building company in the late 19th and early 20th centuries. During World War II, the loch was used as a British Royal Navy submarine base. From 1961 to 1992, it was used as a United States Navy ballistic missile submarine base. In 1992, the Holy Loch base was deemed unnecessary following the demise of the Soviet Union and subsequently closed. Geography Open on the Firth of Clyde at its eastern end, the loch is approximately wide and between long, varying with the tide. Dunoon on the Cowal peninsula lies on the shores of the Clyde just to the s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pounds Per Square Inch
The pound per square inch (abbreviation: psi) or, more accurately, pound-force per square inch (symbol: lbf/in2), is a unit of measurement of pressure or of stress based on avoirdupois units and used primarily in the United States. It is the pressure resulting from a force with magnitude of one pound-force applied to an area of one square inch. In SI units, 1 psi is approximately . The pound per square inch absolute (psia) is used to make it clear that the pressure is relative to a vacuum rather than the ambient atmospheric pressure. Since atmospheric pressure at sea level is around , this will be added to any pressure reading made in air at sea level. The converse is pound per square inch gauge (psig), indicating that the pressure is relative to atmospheric pressure. For example, a bicycle tire pumped up to 65 psig in a local atmospheric pressure at sea level (14.7 psi) will have a pressure of 79.7 psia (14.7 psi + 65 psi). When gauge pressure is referenced to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Horsepower
Horsepower (hp) is a unit of measurement of power, or the rate at which work is done, usually in reference to the output of engines or motors. There are many different standards and types of horsepower. Two common definitions used today are the imperial horsepower as in "hp" or "bhp" which is about , and the metric horsepower as in "cv" or "PS" which is approximately . The electric horsepower "hpE" is exactly , while the boiler horsepower is 9809.5 or 9811 watts, depending on the exact year. The term was adopted in the late 18th century by Scottish engineer James Watt to compare the output of steam engines with the power of draft horses. It was later expanded to include the output power of other power-generating machinery such as piston engines, turbines, and electric motors. The definition of the unit varied among geographical regions. Most countries now use the SI unit watt for measurement of power. With the implementation of the EU Directive 80/181/EEC on 1 January 201 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bore (engine)
In a piston engine, the bore (or cylinder bore) is the diameter of each cylinder. Engine displacement is calculated based on bore, stroke length and the number of cylinders: displacement = The stroke ratio, determined by dividing the bore by the stroke, traditionally indicated whether an engine was designed for power at high engine speeds ( rpm) or torque at lower engine speeds. The term "bore" can also be applied to the bore of a locomotive cylinder or steam engine pistons. In steam locomotives The term bore also applies to the cylinder of a steam locomotive or steam engine. Bore pitch Bore pitch is the distance between the centerline of a cylinder bore to the centerline of the next cylinder bore adjacent to it in an internal combustion engine. It's also referred to as the "mean cylinder width", "bore spacing", "bore center distance" and "cylinder spacing". The bore pitch is always larger than the inside diameter of the cylinder (the bore and piston diameter) sinc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stroke (engine)
In the context of an internal combustion engine, the term stroke has the following related meanings: * A phase of the engine's cycle (e.g. compression stroke, exhaust stroke), during which the piston travels from top to bottom or vice versa. * The type of power cycle used by a piston engine (e.g. two-stroke engine, four-stroke engine). * "Stroke length", the distance travelled by the piston during each cycle. The stroke length, along with bore diameter, determines the engine's displacement. Phases in the power cycle Commonly used engine phases or strokes (i.e. those used in a four-stroke engine) are described below. Other types of engines can have very different phases. Induction-intake stroke The induction stroke is the first phase in a four-stroke (e.g. Otto cycle or Diesel cycle) engine. It involves the downward movement of the piston, creating a partial vacuum that draws an air-fuel mixture (or air alone, in the case of a direct injection engine) into the combustion ...

Hoboken, Antwerp
Hoboken () is a southern Districts of Antwerp, district of the Arrondissements of Belgium, arrondissement and city of Antwerp, in the Flemish Region of Belgium. It is located at the Scheldt river. The name of the district has its origins in Middle Dutch. Name The name Hoboken is derived from Middle Dutch, Medieval Dutch ''Hooghe Buechen'' or ''Hoge Beuken'', meaning ''High'' or ''Tall Beeches''. To this day there is a hospital in Hoboken named "Hoge Beuken". A local children's story says that the name "Hoboken" is derived from a little boy who accidentally dropped his sandwich in the Scheldt, Schelde river, which flows near Hoboken. In the local dialect of Dutch language, Dutch, a "boke" is a sandwich and "ho" is a way of shouting "stop", so he must have shouted "Ho, boken!!!". History The first historical records of Hoboken date from the 1135 parish of ''capellam de hobuechen qua libam''. At that time Hoboken was part of Wilrijk, in the Duchy of Brabant. It has since then ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
