Dynamite Entertainment Titles
Dynamite is an explosive made of nitroglycerin, sorbents (such as powdered shells or clay), and stabilizers. It was invented by the Swedish chemist and engineer Alfred Nobel in Geesthacht, Northern Germany, and was patented in 1867. It rapidly gained wide-scale use as a more robust alternative to the traditional black powder explosives. It allows the use of nitroglycerine's favorable explosive properties while greatly reducing its risk of accidental detonation. History Dynamite was invented by Swedish chemist Alfred Nobel in 1866 and was the first safely manageable explosive stronger than black powder. Alfred Nobel's father, Immanuel Nobel, was an industrialist, engineer, and inventor. He built bridges and buildings in Stockholm and founded Sweden's first rubber factory. His construction work inspired him to research new methods of blasting rock that were more effective than black powder. After some bad business deals in Sweden, in 1838 Immanuel moved his family to Saint ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Douglas Dam
Douglas Dam is a hydroelectric dam on the French Broad River in Sevier County, Tennessee, in the southeastern United States. The dam is operated by the Tennessee Valley Authority (TVA), which built the dam in record time in the early 1940s to meet emergency energy demands at the height of World War II. Douglas Dam is a straight reinforced concrete gravity-type dam 1705 feet (520 m) long and 202 feet (62 m) high, impounding the Douglas Lake. The dam was named for Douglas Bluff, a cliff overlooking the dam site prior to construction.Tennessee Valley Authority, ''The Douglas Project: A Comprehensive Report on the Planning, Design, Construction, and Initial Operations of the Douglas Project'', Technical Report No. 10 (Washington, D.C.: U.S. Government Printing Office, 1949), pp. 1–12, 28.

Nobel Family
The Nobel family ( ), is a prominent Swedish family closely related to the history both of Sweden and of Russia in the 19th and 20th centuries. Its legacy includes its outstanding contributions to philanthropy and to the development of the armament industry and the oil industry. Some of its foremost members are Immanuel Nobel the Younger, the engineer, developer of underwater naval mines and inventor of the rotary lathe used to produce plywood, Ludvig Nobel, the founder of Branobel and one of the richest and the most important men in Russia at his time, and Alfred Nobel, the inventor of dynamite who left the major part of his estate to the creation of the Nobel Prizes. Origins The Nobel family originated from the Scanian village of Östra Nöbbelöv, hence their surname. The first member was Petrus Olai Nobelius (1655–1707) who married Wendela Rudbeck (1668–1710), sister of Olof Rudbeck the Younger, daughter of the famous Swedish scientist Olaus Rudbeck the Elder a ...

Sulfuric Acid
Sulfuric acid (American spelling and the preferred IUPAC name) or sulphuric acid (English in the Commonwealth of Nations, Commonwealth spelling), known in antiquity as oil of vitriol, is a mineral acid composed of the elements sulfur, oxygen, and hydrogen, with the molecular formula . It is a colorless, odorless, and Viscosity, viscous liquid that is Miscibility, miscible with water. Pure sulfuric acid does not occur naturally due to its Dehydration reaction, strong affinity to water vapor; it is Hygroscopy, hygroscopic and readily absorbs water vapor from the Atmosphere of Earth, air. Concentrated sulfuric acid is a strong oxidant with powerful dehydrating properties, making it highly corrosive towards other materials, from rocks to metals. Phosphorus pentoxide is a notable exception in that it is not dehydrated by sulfuric acid but, to the contrary, dehydrates sulfuric acid to sulfur trioxide. Upon addition of sulfuric acid to water, a considerable amount of heat is releas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mercury(II) Fulminate
Mercury(II) fulminate, or Hg(CNO)2, is a primary explosive. It is highly sensitive to friction, heat and shock and is mainly used as a trigger for other explosives in percussion caps and detonators. Mercury(II) cyanate, though its chemical formula is identical, has a different atomic arrangement, making the cyanate and fulminate anionic isomers. First used as a priming composition in small copper caps beginning in the 1820s, mercury fulminate quickly replaced flints as a means to ignite black powder charges in muzzle-loading firearms. Later, during the late 19th century and most of the 20th century, mercury fulminate became widely used in primers for self-contained rifle and pistol ammunition; it was the only practical detonator for firing projectiles until the early 20th century. Mercury fulminate has the distinct advantage over potassium chlorate of being non-corrosive, but it is known to weaken with time, by decomposing into its constituent elements. The reduced mer ...

Percussion Cap
The percussion cap, percussion primer, or caplock, introduced in the early 1820s, is a type of single-use percussion ignition device for muzzle loader firearm locks enabling them to fire reliably in any weather condition. Its invention gave rise to the caplock mechanism or percussion lock system which used percussion caps struck by the hammer to set off the gunpowder charge in rifles and cap and ball firearms. Any firearm using a caplock mechanism is a percussion gun. Any long gun with a cap-lock mechanism and rifled barrel is a percussion rifle. Cap and ball describes cap-lock firearms discharging a single bore-diameter spherical bullet with each shot. Description The percussion cap is a small cylinder of copper or brass with one closed end. Inside the closed end is a small amount of a shock-sensitive explosive material such as mercury fulminate (discovered in 1800; it was the only practical detonator used from about the mid-19th century to the early 20th century). ...

Fuse (explosives)
In an explosive, pyrotechnics, pyrotechnic device, or military munition, a fuse (or fuze) is the part of the device that initiates function. In common usage, the word fuse is used indiscriminately. However, when being specific (and in particular in a military context), the term ''fuse'' describes a simple pyrotechnic initiating device, like the cord on a firecracker whereas the term ''fuze'' is used when referring to a more sophisticated ignition device incorporating mechanical and/or electronics, electronic components, such as a proximity fuze for an M107 projectile, M107 artillery shell, magnetometer, magnetic or acoustic signature, acoustic fuze on a sea mine, spring-loaded grenade fuze, pencil detonator, or anti-handling device. History Documented evidence suggests that the earliest fuses were first used by the Song dynasty, Song Chinese between the 10th and 12th centuries. After the Chinese invented gunpowder, they began adapting its explosive properties for use in milit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Detonator
A detonator is a device used to make an explosive or explosive device explode. Detonators come in a variety of types, depending on how they are initiated (chemically, mechanically, or electrically) and details of their inner working, which often involve several stages. Types of detonators include non-electric and electric. Non-electric detonators are typically stab or pyrotechnic while electric are typically "hot wire" (low voltage), exploding bridge wire (high voltage) or explosive foil (very high voltage). The original electric detonators invented in 1875 independently by Julius Smith and Perry Gardiner used mercury fulminate as the primary explosive. Around the turn of the century performance was enhanced in the Smith-Gardiner blasting cap by the addition of 10-20% potassium chlorate. This compound was superseded by others: lead azide, lead styphnate, some aluminium, or other materials such as DDNP ( diazo dinitro phenol) to reduce the amount of lead emitted into the atm ...

Emil Oskar Nobel
Emil Oskar Nobel ( , ; a.k.a. Oscar; 29 October 1843 – 3 September 1864) was a member of the Nobel family. Biography Emil Nobel was born in Saint Petersburg, Russia. He was the youngest son of Immanuel Nobel (1801–1872) and Karolina Andrietta Ahlsell (1803–1889). He was the brother of Robert Nobel, Ludvig Nobel and Alfred Nobel. In 1842, Immanuel Nobel opened a workshop with foundry in St. Petersburg returning to Sweden in 1859 with his youngest sons Emil and Alfred. Emil was the only member of the family to go to college, attending the University of Uppsala. Emil died together with several other factory workers, the victim of an explosion while experimenting with nitroglycerine at Nobels Sprängolja, his father's factory at Heleneborg in Stockholm. At the time, Nobel was a student in Uppsala, but also helped in the factory. After the explosion, production of nitroglycerin was banned in the factory, but continued close to Heleneborg on an anchored barge in a bay of La ...

Patent
A patent is a type of intellectual property that gives its owner the legal right to exclude others from making, using, or selling an invention for a limited period of time in exchange for publishing an sufficiency of disclosure, enabling disclosure of the invention."A patent is not the grant of a right to make or use or sell. It does not, directly or indirectly, imply any such right. It grants only the right to exclude others. The supposition that a right to make is created by the patent grant is obviously inconsistent with the established distinctions between generic and specific patents, and with the well-known fact that a very considerable portion of the patents granted are in a field covered by a former relatively generic or basic patent, are tributary to such earlier patent, and cannot be practiced unless by license thereunder." – ''Herman v. Youngstown Car Mfg. Co.'', 191 F. 579, 584–85, 112 CCA 185 (6th Cir. 1911) In most countries, patent rights fall under private la ...

Ascanio Sobrero
Ascanio Sobrero (12 October 1812 – 26 May 1888) was an Italian chemist, born in Casale Monferrato. He studied under Théophile-Jules Pelouze at the University of Turin, who had worked with the explosive material guncotton. Education and career He studied medicine in Turin and Paris and then chemistry at the University of Gießen with Justus Liebig, and earned his doctorate in 1832. In 1845 he became a professor at the University of Turin. During his research he discovered, in 1847, nitroglycerine. He initially called it "pyroglycerine", and warned vigorously against its use. In fact, he was so frightened by what he created that he kept it a secret for over a year. Another of Pelouze's students was the young Alfred Nobel, who returned to the Nobel family's defunct armaments factory and began experimenting with the material around 1860; it did, indeed prove to be very difficult to discover how to handle it safely. In the 1860s Nobel received several patents around the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
