SS Samuel Q. Brown
''Samuel Q. Brown'' was a steam tanker built in 1920–1921 by Merchant Shipbuilding Corporation of Chester for Tide Water Oil Co., a subsidiary of Standard Oil, with intention of operating between New York and the oil-producing ports of the southern United States and Mexico. Design and construction Early in 1920 Tide Water Oil Co. decided to add several modern tankers to expand their fleet of four vessels operating between the southern oil ports and New York and New Jersey. A contract for two of them, of approximately 10,000 deadweight tonnage, was awarded to the Merchant Shipbuilding Corp. and the ship was laid down at the shipbuilder's yard in Chester (yard number 384) on 1 October 1920, and launched on 15 October 1921, with Miss Louise Van Voorhees of New York, granddaughter of late Samuel Queen Brown, serving as the sponsor. The ship was named after Samuel Queen Brown, one of the founders of Tide Water Pipe Co. and former president of the Chester Oil Company. The tanker was ...

Standard Oil
Standard Oil Company, Inc., was an American oil production, transportation, refining, and marketing company that operated from 1870 to 1911. At its height, Standard Oil was the largest petroleum company in the world, and its success made its co-founder and chairman, John D. Rockefeller, who is among the wealthiest Americans of all time and among the richest people in modern history. Its history as one of the world's first and largest multinational corporations ended in 1911, when the U.S. Supreme Court ruled that it was an illegal monopoly. The company was founded in 1863 by Rockefeller and Henry Flagler, and was incorporated in 1870. Standard Oil dominated the oil products market initially through horizontal integration in the refining sector, then, in later years vertical integration; the company was an innovator in the development of the business trust. The Standard Oil trust streamlined production and logistics, lowered costs, and undercut competitors. "Trust-busting" cri ...

Tuxpan
Tuxpan (or Túxpam, fully Túxpam de Rodríguez Cano) is both a municipality and city located in the Mexican state of Veracruz. The population of the city was 78,523 and of the municipality was 134,394 inhabitants, according to the INEGI census of 2005, residing in a total area of . The municipality includes many smaller outlying communities, the largest of which are Alto Lucero and Santiago de la Peña. A local beachside community is also nearby. Overview Tuxpan or Túxpam, pronounced in Nahuatl, the language of the ancient Aztecs, literally means "Place of Rabbits", a compound of ''tochtli'' "rabbit" and ''-pan'' "place". The city is located on the banks of the Tuxpan River, which reaches the Gulf of Mexico downstream . Being the nearest port to Mexico City, Tuxpan is an important commercial link for Mexican imports and exports. Tuxpan is now primarily a grain port, with emphasis on soybeans and maize. Off-shore links to oil pipelines are used to transfer petroleum produc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tamiahua
Tamiahua is a municipality located in the northern part of the state of Veracruz in Mexico. It covers an area of 985.4 km2. It is located at the southern end of the Tamiahua Lagoon. The name may come from the Náhuatl language ''Tla-mia-hua-c'': "In the flowers of maize of the land"; or Huasteco, ''Tam-yan-ja'': "Place of great waters". Geographic Limits The municipality of Tamiahua is delimited to the north by Ozuluama and Tampico Alto, to the east by Gulf of Mexico, to the south by Temapache and Tuxpam de Rodríguez Cano, and to the west by Tamalín, Chinampa de Gorostiza, Naranjos Amatlán, Tancoco and Cerro Azul.

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 a air-fuel mixture (or air alone, in the case of a direct injection engine) into the combus ...

Triple Expansion Steam Engine
A compound steam engine unit is a type of steam engine where steam is expanded in two or more stages. A typical arrangement for a compound engine is that the steam is first expanded in a high-pressure ''(HP)'' cylinder, then having given up heat and losing pressure, it exhausts directly into one or more larger-volume low-pressure ''(LP)'' cylinders. Multiple-expansion engines employ additional cylinders, of progressively lower pressure, to extract further energy from the steam. Invented in 1781, this technique was first employed on a Cornish beam engine in 1804. Around 1850, compound engines were first introduced into Lancashire textile mills. Compound systems There are many compound systems and configurations, but there are two basic types, according to how HP and LP piston strokes are phased and hence whether the HP exhaust is able to pass directly from HP to LP ( Woolf compounds) or whether pressure fluctuation necessitates an intermediate "buffer" space in the form of a st ...

Hull (watercraft)
A hull is the watertight body of a ship, boat, or flying boat. The hull may open at the top (such as a dinghy), or it may be fully or partially covered with a deck. Atop the deck may be a deckhouse and other superstructures, such as a funnel, derrick, or mast. The line where the hull meets the water surface is called the waterline. General features There is a wide variety of hull types that are chosen for suitability for different usages, the hull shape being dependent upon the needs of the design. Shapes range from a nearly perfect box in the case of scow barges to a needle-sharp surface of revolution in the case of a racing multihull sailboat. The shape is chosen to strike a balance between cost, hydrostatic considerations (accommodation, load carrying, and stability), hydrodynamics (speed, power requirements, and motion and behavior in a seaway) and special considerations for the ship's role, such as the rounded bow of an icebreaker or the flat bottom of a landing craft. ...

Beam (nautical)
The beam of a ship is its width at its widest point. The maximum beam (BMAX) is the distance between planes passing through the outer extremities of the ship, beam of the hull (BH) only includes permanently fixed parts of the hull, and beam at waterline (BWL) is the maximum width where the hull intersects the surface of the water. Generally speaking, the wider the beam of a ship (or boat), the more initial stability it has, at the expense of secondary stability in the event of a capsize, where more energy is required to right the vessel from its inverted position. A ship that heels on her ''beam ends'' has her deck beams nearly vertical. Typical values Typical length-to-beam ratios ( aspect ratios) for small sailboats are from 2:1 (dinghies to trailerable sailboats around ) to 5:1 (racing sailboats over ). Large ships have widely varying beam ratios, some as large as 20:1. Rowing shells designed for flatwater racing may have length to beam ratios as high as 30:1, while a cor ...

Length Between Perpendiculars
Length between perpendiculars (often abbreviated as p/p, p.p., pp, LPP, LBP or Length BPP) is the length of a ship along the summer load line from the forward surface of the stem, or main bow perpendicular member, to the after surface of the sternpost, or main stern perpendicular member. When there is no sternpost, the centerline axis of the rudder stock is used as the aft end of the length between perpendiculars. Measuring to the stern post or rudder stock was believed to give a reasonable idea of the ship's carrying capacity, as it excluded the small, often unusable volume contained in her overhanging ends. On some types of vessels this is, for all practical purposes, a waterline measurement. In a ship with raked stems, naturally that length changes as the draught of the ship changes, therefore it is measured from a defined loaded condition. See also * Length overall __NOTOC__ Length overall (LOA, o/a, o.a. or oa) is the maximum length of a vessel's hull measured para ...

Lee De Forest
Lee de Forest (August 26, 1873 – June 30, 1961) was an American inventor and a fundamentally important early pioneer in electronics. He invented the first electronic device for controlling current flow; the three-element "Audion" triode vacuum tube in 1906. This started the Electronic Age, and enabled the development of the electronic amplifier and oscillator. These made radio broadcasting and long distance telephone lines possible, and led to the development of talking motion pictures, among countless other applications. He had over 300 patents worldwide, but also a tumultuous career— he boasted that he made, then lost, four fortunes. He was also involved in several major patent lawsuits, spent a substantial part of his income on legal bills, and was even tried (and acquitted) for mail fraud. Despite this, he was recognised for his pioneering work with the 1922 IEEE Medal of Honor, the 1923 Franklin Institute Elliott Cresson Medal and the 1946 American Institute of ...

Longitudinal Framing
Longitudinal framing (also called the Isherwood system after British naval architect Sir Joseph Isherwood, who patented it in 1906) is a method of ship construction in which large, widely spaced transverse frames are used in conjunction with light, closely spaced longitudinal members. This method, Isherwood felt, lent a ship much greater longitudinal strength than in ships built in the traditional method, where a series of closely spaced transverse frames are fitted from the keel to the sheer line, with corresponding deck beams, a method that is well suited to support longitudinal planking. Longitudinal framing was a known method of shipbuilding before Isherwood. Naval engineer J. Scott Russell, for instance, had built several longitudinally framed ships, including the SS ''Great Eastern''. However, no one had made the process practical from a commercial standpoint, which was Isherwood's achievement. The first commercial vessel constructed with the Isherwood system, the oil-t ...
