After Texaco merged with Chevron in , Shell purchased Texaco's shares in the joint ventures. In recent years The Shell Oil Company's Midstream, and Downstream, in particular, have become limited to petroleum, and chemical products.

This has come as a result of Royal Dutch Shell breaking off its Natural Gas and power businesses into a new segment named Integrated Gas. The Shell Oil Company's former Natural Gas, and energy divisions are now Shell Energy North America, a closely integrated, but a distinctive entity that runs across North America and is headquartered out of Houston. Until the mids Shell's business in the United States was substantially independent. Limited direct involvement from the main office in The Hague , Netherlands and having its stock "Shell Oil" traded on the New York Stock Exchange were factors.

Despite the acquisition, however, Shell Oil remained a fairly independent business. This was due in part to complex legal reasons as Royal Dutch Shell feared that there could be onerous liability problems if a closer control of Shell Oil's affairs was exercised by the "parent company". One consequence of this independence was that the Shell logo used in the U.

The logo used in the United States is the same as that used elsewhere since June 1, The takeover was part of the global New Energies project, with the aim of bringing solar renewable options to US customers.

In October , the company installed a foot-high quench tower at the Shell Chemical Appalachia L. Pittsburgh plant, which transfers heat absorbed by the water circulation process to use across other areas of the site. Shell has companies in North, South and Central America: in Argentina, Aruba, Barbados, the Bahamas, Bolivia, Brazil, Canada, Chile, Colombia, Costa Rica, The Dominican Republic, Ecuador, Guatemala, Honduras, Mexico, Nicaragua, Panama, Peru, Puerto Rico, Suriname, Trinidad and Tobago, Uruguay, the U.

Shell also has companies in Africa, Europe, the Middle East, and Asia. As of [update] , it was listed as "high priority violator" since In , a lawsuit was filed against Shell Oil Company for alleged Clean Air Act violation. Shell Deer Park facility, 20 miles east of Houston, was the nation's eighth-largest oil refinery and one of the world's largest petrochemical producers. The facility was also the second-largest source of air pollution in Harris County , which ranked among the lowest in the nation in several measures of air quality.

Will Oremus from Slate magazine states, "The company's business depends on being able to anticipate and respond quickly to seismic shifts in the energy market. So it employs a team of big-thinking futurists, called scenario planners, to keep it a step ahead. In the company released a fresh pair of scenarios for how the world might respond to climate change over the coming decades.

Both were predicated on what the company called 'three hard truths': that global energy demand is rising, that the supply of conventional energy will not be able to keep up, and that climate change is both real and dangerous.

Between and , Shell Oil produced polybutylene pipes, which corrode when exposed to chlorine. A class action lawsuit was filed in against Shell Oil when the polybutylene pipes caused flooding in many households in the U. During his address, Trump called out specific union leaders to declare their voting loyalty.

An escape sequence can be defined, using either a special local keystroke that is never passed on but always interpreted by the local system. The program becomes modal, switching between interpreting commands from the keyboard or passing keystrokes on as data to be processed.

A feature of many command-line shells is the ability to save sequences of commands for re-use. A data file can contain sequences of commands which the CLI can be made to follow as if typed in by a user.

Special features in the CLI may apply when it is carrying out these stored instructions. Such batch files script files can be used repeatedly to automate routine operations such as initializing a set of programs when a system is restarted.

Batch mode use of shells usually involves structures, conditionals, variables, and other elements of programming languages; some have the bare essentials needed for such a purpose, others are very sophisticated programming languages in and of themselves. Conversely, some programming languages can be used interactively from an operating system shell or in a purpose-built program.

The command-line shell may offer features such as command-line completion , where the interpreter expands commands based on a few characters input by the user. A command-line interpreter may offer a history function, so that the user can recall earlier commands issued to the system and repeat them, possibly with some editing. Since all commands to the operating system had to be typed by the user, short command names and compact systems for representing program options were common.

Short names were sometimes hard for a user to recall, and early systems lacked the storage resources to provide a detailed on-line user instruction guide. A graphical user interface GUI provides means for manipulating programs graphically, by allowing for operations such as opening, closing, moving and resizing windows , as well as switching focus between windows.

Graphical shells may be included with desktop environments or come separately, even as a set of loosely coupled utilities. Graphical shells typically build on top of a windowing system. In the case of X Window System or Wayland , the shell consists of an X window manager or a Wayland compositor , respectively, as well as of one or multiple programs providing the functionality to start installed applications, to manage open windows and virtual desktops, and often to support a widget engine.

In the case of macOS , Quartz could be thought of as the windowing system, and the shell consists of the Finder , [5] the Dock , [5] SystemUIServer, [5] and Mission Control. Modern versions of the Microsoft Windows operating system use the Windows shell as their shell.

Windows Shell provides desktop environment , start menu , and task bar , as well as a graphical user interface for accessing the file management functions of the operating system. Older versions also include Program Manager , which was the shell for the 3. The interfaces of Windows versions 1 and 2 were markedly different. Desktop applications are also considered shells, as long as they use a third-party engine. Likewise, many individuals and developers dissatisfied with the interface of Windows Explorer have developed software that either alters the functioning and appearance of the shell or replaces it entirely.

WindowBlinds by StarDock is a good example of the former sort of application. LiteStep and Emerge Desktop are good examples of the latter. Interoperability programmes and purpose-designed software lets Windows users use equivalents of many of the various Unix-based GUIs discussed below, as well as Macintosh. These are also sometimes referred to as "wrappers".

In expert systems , a shell is a piece of software that is an "empty" expert system without the knowledge base for any particular application. From Wikipedia, the free encyclopedia. Computer program which exposes an operating system's services to a human user or other program. By World War II they were superseded in Royal Navy service by common pointed capped CPC and semi-armor piercing SAP , filled with TNT. Common lyddite shells were British explosive shells filled with Lyddite were initially designated "common lyddite" and beginning in were the first British generation of modern "high explosive" shells.

Its French equivalent was "melinite", Japanese equivalent was "shimose". Common lyddite shells "detonated" and fragmented into small pieces in all directions, with no incendiary effect. For maximum destructive effect the explosion needed to be delayed until the shell had penetrated its target. Early shells had walls of the same thickness for the whole length, later shells had walls thicker at the base and thinning towards the nose. Proper detonation of a lyddite shell would show black to grey smoke, or white from the steam of a water detonation.

Yellow smoke indicated simple explosion rather than detonation, and failure to reliably detonate was a problem with lyddite, especially in its earlier usage. To improve the detonation "exploders" with a small quantity of picric powder or even of TNT in smaller shells, 3 pdr, 12 pdr — 4. Lyddite presented a major safety problem because it reacted dangerously with metal bases. This required that the interior of shells had to be varnished, the exterior had to be painted with leadless paint and the fuze-hole had to be made of a leadless alloy.

Fuzes containing any lead could not be used with it. When World War I began Britain was replacing lyddite with modern "high explosive" HE such as TNT. After World War I the term "common lyddite" was dropped, and remaining stocks of lyddite-filled shells were referred to as HE high explosive shell filled lyddite.

Hence "common" faded from use, replaced by "HE" as the explosive shell designation. Common lyddite shells in British service were painted yellow, with a red ring behind the nose to indicate the shell had been filled. The mine shell is a particular form of HE shell developed for use in small caliber weapons such as 20 mm to 30 mm cannon. Small HE shells of conventional design can contain only a limited amount of explosive. By using a thin-walled steel casing of high tensile strength, a larger explosive charge can be used.

The mine shell concept was invented by the Germans in the Second World War primarily for use in aircraft guns intended to be fired at opposing aircraft. The aluminium structures and skins of Second World War aircraft were readily damaged by this greater level of blast.

Shrapnel shells are an anti-personnel munition which delivered large numbers of bullets at ranges far greater than rifles or machine guns could attain — up to 6, yards by The gunner set the shell's time fuze so that it was timed to burst as it was angling down towards the ground just before it reached its target ideally about yards before, and 60— feet above the ground [33]. A trained gun team could fire 20 such shells per minute, with a total of 6, balls, which compared very favorably with rifles and machine-guns.

However, shrapnel's relatively flat trajectory it depended mainly on the shell's velocity for its lethality, and was lethal only in the forward direction meant that it could not strike trained troops who avoided open spaces and instead used dead ground dips , shelters, trenches, buildings, and trees for cover.

It was of no use in destroying buildings or shelters. Cluster shells are a type of carrier shell or cargo munition. Like cluster bombs , an artillery shell may be used to scatter smaller sub-munitions, including anti-personnel grenades , anti-tank top-attack munitions, and landmines.

Many modern armies make significant use of cluster munitions in their artillery batteries. Chemical shells contain just a small explosive charge to burst the shell, and a larger quantity of a chemical agent or riot control agent of some kind, in either liquid, gas or powdered form.

In some cases such as the M Sarin gas shell, the payload is stored as two precursor chemicals which are mixed after the shell is fired. All signatories have renounced the use of both lethal chemical agents and incapacitating agents in warfare. At a minimum the USA, USSR and France each independently developed nuclear artillery shells to provide battlefield scale nuclear weapons for tactical use. These range from the relatively small mm shell all the way up to the mm shell usable by heavy Battleship cannon and shore defense units equipped with the same guns.

Not all shells are designed to kill or destroy. The following types are designed to achieve particular non-lethal effects. They are not completely harmless: smoke and illumination shells can accidentally start fires, and impact by the discarded carrier of all three types can wound or kill personnel, or cause minor damage to property. Smoke shells are used to create smoke screens to mask movements of friendly forces or disorient enemies, or to mark specific areas.

The main types are bursting using a payload powdered chemicals and base ejection delivering three or four smoke canisters which are deployed from the rear of the shell prior to impact, or a single canister containing submunitions distributed via a bursting charge. Base ejection shells are a type of carrier shell or cargo munition. Base ejection smoke is usually white, however, colored smoke has been used for marking purposes.

The original canisters typically used hexachloroethane - zinc HC , modern ones use red phosphorus because of its multi-spectral properties. However, other compounds have been used; in World War II, Germany used oleum fuming sulfuric acid and pumice.

Due to the nature of their payload, powder smoke shells using white phosphorus in particular have a secondary effect as incendiary weapons, though they are not as effective in this role as dedicated weapons using thermite.

Modern illuminating shells are a type of carrier shell or cargo munition. Those used in World War I were shrapnel pattern shells ejecting small burning 'pots'.

A modern illumination shell has a time fuze that ejects a flare 'package' through the base of the carrier shell at a standard height above ground typically about metres , from where it slowly falls beneath a non-flammable parachute , illuminating the area below. The ejection process also initiates a pyrotechnic flare emitting white or 'black' infrared light.

Typically illumination flares burn for about 60 seconds. These are also known as starshell or star shell. Both white and black light illuminating shells may be used to provide continuous illumination over an area for a period of time, and may use several dispersed aimpoints to illuminate a large area.

Alternatively firing single illuminating shells may be coordinated with the adjustment of HE shell fire onto a target. The carrier shell is simply a hollow carrier equipped with a fuze that ejects the contents at a calculated time. They are often filled with propaganda leaflets see external links , but can be filled with anything that meets the weight restrictions and is able to withstand the shock of firing. Famously, on Christmas Day during the siege of Ladysmith , the Boers fired into Ladysmith a carrier shell without a fuze, which contained a Christmas pudding , two Union Flags and the message "compliments of the season".

The shell is still kept in the museum at Ladysmith. A proof shot is not used in combat but to confirm that a new gun barrel can withstand operational stresses. The proof shot is heavier than a normal shot or shell, and an oversize propelling charge is used, subjecting the barrel to greater than normal stress. The proof shot is inert no explosive or functioning filling and is often a solid unit, although water, sand or iron powder filled versions may be used for testing the gun mounting.

Although the proof shot resembles a functioning shell of whatever sort , so that it behaves as a real shell in the barrel, it is not aerodynamic as its job is over once it has left the muzzle of the gun. Consequently, it travels a much shorter distance and is usually stopped by an earth bank for safety measures. The gun, operated remotely for safety in case it fails, fires the proof shot, and is then inspected for damage.

If the barrel passes the examination, " proof marks " are added to the barrel. The gun can be expected to handle normal ammunition, which subjects it to less stress than the proof shot, without being damaged. Guided or "smart" ammunition features some method of guiding itself post-launch, usually through the addition of steering fins that alter its trajectory in an unpowered glide.

Due to their much higher cost, they have yet to supplant unguided munitions in all applications. M Excalibur. A GPS guided artillery shell. M Copperhead approaches a target tank. SMArt An anti-armor shell containing two autonomous, sensor-guided, fire-and-forget submunitions. The fuze of a shell has to keep the shell safe from accidental functioning during storage, due to possibly rough handling, fire, etc. It also has to survive the violent launch through the barrel, then reliably function at the appropriate moment.

To do this it has a number of arming mechanisms which are successively enabled under the influence of the firing sequence. This may be due to a shallow trajectory of fire, low-velocity firing or soft impact conditions.

Whatever the reason for failure, such a shell is called a blind or unexploded ordnance UXO the older term, "dud", is discouraged because it implies that the shell cannot detonate. Blind shells often litter old battlefields; depending on the impact velocity, they may be buried some distance into the earth, all the while remaining potentially hazardous.

For example, antitank ammunition with a piezoelectric fuze can be detonated by relatively light impact to the piezoelectric element, and others, depending on the type of fuze used, can be detonated by even a small movement.

The battlefields of the First World War still claim casualties today from leftover munitions. Modern electrical and mechanical fuzes are highly reliable: if they do not arm correctly, they keep the initiation train out of line or if electrical in nature discharge any stored electrical energy.

A shell is a payload-carrying projectile that, as opposed to a solid round Wiikipediacontains an explosiveincendiaryor other chemical filling, though modern usage sometimes includes large solid Shel projectiles properly termed shot. Originally it was called a bombshell Olivia Caliban, but "shell" has come to be unambiguous in a military context.

All explosive- and incendiary-filled projectiles, particularly for mortarswere originally called grenadesderived She,l the French word for pomegranateso called because of the similarity of shape and that the multi-seeded fruit resembles the powder-filled, fragmentizing bomb.

Words cognate with grenade are still used for an artillery or mortar projectile in some European languages. The shape is usually a cylinder topped by an ogive -tipped nose cone for good aerodynamic performanceand possibly with a tapered boat tail ; but some specialized types differ widely. Solid cannonballs "shot" did not need a fuse. However, hollow munitions "shells" filled with something such as gunpowder Shell Wikipedia fragment the ball needed a fuse that was either impact triggered percussion or time delayed.

Therefore, ball shells needed a time fuse that was ignited before She,l during firing and burned until the shell reached its target. The earliest record of shells being used in combat was by the Republic of Venice at Wikiledia in Shells with fuses were used at the siege of St Boniface in Corsica.

These were two hollowed hemispheres of stone or bronze held together by an iron hoop. Hollow, gunpowder-packed shells made of cast iron are described in the early Ming Dynasty Chinese military manual Huolongjingwritten some time before At least since the 16th century grenades made of ceramics or glass were in use in Shell Wikipedia Europe. A hoard of several hundred ceramic grenades dated to the 17th century was discovered during building works in front of Wikipecia bastion of the Bavarian city of IngolstadtGermany.

Many of the grenades contained their original blackpowder loads and igniters. An early problem was that there was no means of precisely measuring the Wikipeida to detonation — reliable fuses did not yet exist and the burning time of the powder fuse was subject to considerable trial and error.

Early powder burning fuses had to be loaded fuse down to be ignited by firing or a portfire or slow match put down Shell Wikipedia barrel to light the fuse.

Other shells were wrapped in bitumen cloth, which would ignite during the firing and in turn ignite Eva Angelina Imdb powder fuse.

Nevertheless, shells came into regular use in the 16th century, for example a English mortar shell was filled with 'wildfire'. By the 18th century, it was known that the fuse toward the muzzle could be lit by the flash through the windage between the shell and the barrel.

At about this time, shells began to be Shell Wikipedia for horizontal fire from howitzers with a small propelling charge and, inexperiments demonstrated that they could be used from guns with heavier charges. The Pcschiedel of exploding shells from field artillery became relatively commonplace from early in the 19th century. Until the mid 19th century, shells remained as simple exploding spheres that used gunpowder, set off by a slow burning fuse.

They were usually made of cast ironbut bronzeleadbrass and even glass shell casings were experimented with. Wukipedia, the thickness of the metal body was about a sixth of their diameter and they were about two-thirds the weight of solid shot of the same caliber. To ensure that shells were loaded with their fuses toward the muzzle, they were Wikipecia to wooden bottoms called sabots. Ina committee of British artillery officers recognized that they were essential stores and in Britain standardized sabot thickness as a half-inch.

Despite the use of exploding shells, the use of smoothbore cannons firing spherical projectiles of shot remained the dominant artillery method until the s. The mid 19th century saw a revolution in artillery, with the introduction Shell Wikipedia the first practical rifled breech loading weapons.

The new methods resulted in the reshaping of the spherical shell into its modern recognizable cylindro-conoidal form.

This shape greatly improved the Sex Blonde Girl stability of the projectile and meant that the primitive time Novum Arnsberg could be Cuckold Privat with the percussion fuze situated in the nose of the shell.

The new shape also meant that further, armor-piercing designs could be used. During the 20th Century, shells became increasingly streamlined. In World War I, ogives were typically two circular radius head crh — the curve was a segment of a circle having a radius of twice the shell caliber. From the Shell Wikipedia, higher quality steels were introduced by some countries for their HE shells, this enabled thinner shell walls with less weight of metal and hence a greater weight of explosive.

Ogives were further elongated to improve their ballistic performance. Advances in metallurgy in the industrial era allowed for the construction of rifled breech-loading guns that could fire at a much greater muzzle velocity. After the British artillery was shown Clitty in the Crimean War as having barely changed since the Napoleonic Warsthe industrialist William Armstrong was awarded a contract by the government to design a new piece of artillery.

Production started in at Wikipdia Elswick Ordnance Company and the Royal Arsenal at Woolwich. Although rifling had been tried on small arms since the 15th century, the necessary machinery to accurately rifle artillery only became available in Kirsten Dunst Sex Tape midth century.

Martin von Wahrendorff and Joseph Whitworth independently produced rifled cannons in the s, but it was Armstrong's gun that was first to see widespread use during the Crimean War. This spin, together with the elimination of windage as a result of the tight fit, enabled the gun to achieve greater range and accuracy than existing smooth-bore muzzle-loaders with a smaller powder charge. The gun was also a breech-loader. Although attempts at breech-loading mechanisms had been made since medieval times, the essential engineering problem was that the mechanism couldn't Wikipsdia the explosive charge.

It was only with the advances in metallurgy and precision engineering capabilities during the Industrial Revolution that Armstrong was able to construct a viable solution. Another innovative feature was what Armstrong called its "grip", which Teen Cameltoe Jeans essentially a squeeze bore ; the 6 inches of the bore at the muzzle end was of slightly smaller diameter, which centered the shell before it left the barrel and at the same time slightly swaged down its lead coating, reducing its Pornhub Video Downloder and slightly improving its ballistic qualities.

Rifled guns were also developed elsewhere — by Major Giovanni Cavalli and Baron Wikipediaa von Wahrendorff in Sweden, Krupp in Germany and the Wiard gun in the United States. Lead coated shells were used with the Armstrong gunbut were not satisfactory so Babydollbbw Com projectiles were adopted. However, these did not seal the gap between shell and barrel.

Wads at the shell base were also tried without success. Inthe British adopted a copper ' gas-check ' at Wikipecia base of their studded projectiles and in tried a rotating gas check to replace the studs, leading to the automatic gas-check.

This was soon followed by the Vavaseur copper driving band as part of Wiipedia projectile. The driving band rotated the projectile, centered it in the bore and prevented gas escaping forwards. A driving band has to be soft but tough enough to prevent stripping by rotational and engraving stresses. Although an early percussion fuze appeared in that used a flint to create sparks to ignite the powder, the shell had to fall in a particular way for this to work and this did not work with Wikipedai projectiles.

An additional problem was finding a suitably stable 'percussion powder'. Progress was Shell Wikipedia possible until the discovery of mercury fulminate inleading to priming mixtures for small arms Wikioedia by the Rev Alexander Forsythand the copper percussion cap in The percussion fuze was adopted by Britain in Many designs were jointly examined by the army and navy, but were unsatisfactory, probably Iwg Ilmenau of the safety and arming features.

However, Sheell the design by Quartermaster Freeburn of the Royal Artillery was adopted by the army. It was a wooden fuze some Critique Rse inches long and used shear wire to hold blocks between the fuze magazine and a burning match.

The match was ignited by propellant flash and the shear wire broke on impact. A British naval percussion fuze made of metal did not appear until Gunpowder was used as the only form of explosive up until the end of the 19th century.

Guns using black powder ammunition would have their view obscured by a huge cloud of smoke and concealed shooters were Shell Wikipedia away by a cloud of smoke over the firing position. Guncottona nitrocellulose-based material, was discovered by Swiss chemist Christian Friedrich Schönbein in He promoted its use as a blasting explosive [14] and sold manufacturing rights to the Austrian Empire.

British interest waned after Shel explosion destroyed the Faversham factory in Small arms Porn Gid not withstand the pressures generated by guncotton.

Abel patented this process inwhen the second Austrian guncotton factory exploded. After the Stowmarket factory exploded inWaltham Abbey began production of guncotton for torpedo and mine warheads. InPaul Vieille invented a smokeless powder called Poudre B short for poudre blanche —white powder, as distinguished from black powder [16] made from This Shell Wikipedia adopted for the Lebel rifle.

Higher muzzle velocity meant a flatter trajectory and less wind drift and bullet drop, making meter shots practicable. Other European countries swiftly followed and Danuta Lato Tits using their own versions of Poudre B, the first being Germany and Austria which introduced new weapons in Subsequently, Poudre B was modified several times with various compounds being added and removed. Krupp began Wikipediq diphenylamine as a stabilizer in Britain conducted trials on all the various types of propellant brought to their attention, but were dissatisfied with them all and sought something superior to all existing types.

InSir Frederick AbelJames Dewar and Dr W Kellner patented Nos and 11, in the names of Abel and Dewar a new formulation that was manufactured at the Royal Gunpowder Factory at Waltham Abbey. It entered British service in as Cordite Mark 1. Cordite could be made in any desired shape or size. A variety of fillings have been used in shells throughout history. An incendiary shell was invented by Valturio in The carcass shell was first used by the French under Louis XIV in Their use continued well into the 19th century.

A modern version of the incendiary shell was developed in by the British and was known as Martin's shell after its inventor. The shell was filled with molten iron and was intended to break up on impact with an enemy ship, splashing molten iron on the target. It was used by the Royal Navy between andreplacing heated shot as an anti-ship, incendiary projectile.

Two patterns of incendiary shell were used by the British in World War 1, one designed for use against Zeppelins. Similar to incendiary shells were star shells, designed for illumination rather than arson. Sometimes called lightballs they were in use from the 17th Century onwards. The inch wasn't officially declared obsolete until Smoke balls also date back to the 17th Century, British ones contained a mix of saltpetre, coal, pitch, tar, resin, sawdust, crude antimony and sulphur.

They produced a 'noisome smoke in abundance that is impossible to bear'. They were used to 'suffocate or expel the enemy Sgell casemates, mines or between decks; for concealing operations; and as signals. Shells filled with poison gas were used from onwards. Artillery shells are differentiated by how the shell is loaded, propelled and the type of breech mechanism:.

With this style of ammunition, there are three main components the fuzed projectile, the casing to hold the propellants and primerand the single propellant charge.

With a fixed round everything is included in one ready to use package and in British ordnance, terms are called fixed quick firing.
