Parker 51
The Parker 51 is a fountain pen first introduced in 1941. Parker marketed it as “The World’s Most Wanted Pen,” a slogan alluding to restrictions on production of consumer goods for civilian markets in the United States during World War II. Parker's continual advertising during the war created demand that took several years to fulfil after the end of the conflict. The pen and the ink were both named "51" to mark 1939, the company's 51st anniversary, during which development for the pen was completed (U.S. design patent No. 116,097, filed). By giving the pen a number instead of a name, Parker avoided the problem of translating a name into other languages. Design and history The "51" was innovative for the period. With a number of new design features in particular its hooded, tubular nib and multi-finned collector, were designed to work in conjunction with the pen's proprietary ink. This allowed the tubular nib to stay wet and lay down an even line with either the ultra-f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fountain Pen
A fountain pen is a writing instrument which uses a metal nib to apply a water-based ink to paper. It is distinguished from earlier dip pens by using an internal reservoir to hold ink, eliminating the need to repeatedly dip the pen in an inkwell during use. The pen draws ink from the reservoir through a feed to the nib and deposits the ink on paper via a combination of gravity and capillary action. Filling the reservoir with ink may be achieved manually, via the use of an eyedropper or syringe, or via an internal filling mechanism which creates suction (for example, through a piston mechanism) or a vacuum to transfer ink directly through the nib into the reservoir. Some pens employ removable reservoirs in the form of pre-filled ink cartridges. History Early prototypes of reservoir pens According to Qadi al-Nu'man al-Tamimi (d. 974) in his ''Kitab al-Majalis wa 'l-musayarat'', the Fatimid caliph Al-Mu'izz li-Din Allah in Arab Egypt demanded a pen that would not stain his h ...

Parker Pen Company
The Parker Pen Company is a French manufacturer of luxury writing pens, founded in 1888 by George Safford Parker in Janesville, Wisconsin, United States. In 2011 the Parker factory at Newhaven, East Sussex, England, was closed, and its production transferred to Nantes, France. History George Safford Parker, the founder, had previously been a sales agent for the John Holland Gold Pen Company. He received his first fountain pen related patent in 1889. In 1894 Parker received a patent on his "Lucky Curve" fountain pen feed, which was claimed to draw excess ink back into the pen barrel when the pen was not in use. The company's first successful pen, released in 1899, was the Parker Jointless. The Lucky Curve feed was used in various forms until 1928. From the 1920s to the 1960s, before the development of the ballpoint pen, Parker was either number one or number two in worldwide writing instrument sales. In 1931, Parker created Quink (quick drying ink), which eliminated the need ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 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 law and the patent holder mus ...

P-51 Mustang
The North American Aviation P-51 Mustang is an American long-range, single-seat fighter and fighter-bomber used during World War II and the Korean War, among other conflicts. The Mustang was designed in April 1940 by a team headed by James H. Kindelberger of North American Aviation (NAA) in response to a requirement of the British Purchasing Commission. The Purchasing Commission approached North American Aviation to build Curtiss P-40 fighters under license for the Royal Air Force (RAF). Rather than build an old design from another company, North American Aviation proposed the design and production of a more modern fighter. The prototype NA-73X airframe was rolled out on 9 September 1940, 102 days after the contract was signed, and first flew on 26 October. The Mustang was designed to use the Allison V-1710 engine, which had limited high-altitude performance in its earlier variants. The aircraft was first flown operationally by the RAF as a tactical-reconnaissance aircraf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fighter Plane
Fighter aircraft are fixed-wing military aircraft designed primarily for air-to-air combat. In military conflict, the role of fighter aircraft is to establish air superiority of the battlespace. Domination of the airspace above a battlefield permits bombers and attack aircraft to engage in tactical and strategic bombing of enemy targets. The key performance features of a fighter include not only its firepower but also its high speed and maneuverability relative to the target aircraft. The success or failure of a combatant's efforts to gain air superiority hinges on several factors including the skill of its pilots, the tactical soundness of its doctrine for deploying its fighters, and the numbers and performance of those fighters. Many modern fighter aircraft also have secondary capabilities such as ground attack and some types, such as fighter-bombers, are designed from the outset for dual roles. Other fighter designs are highly specialized while still filling the main ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quink
Quink (a portmanteau from 'quick' and 'ink') is a fountain pen ink developed by the Parker Pen Company. It was introduced in 1931 and has remained in production ever since. Background In 1928, under the direction of Kenneth Parker, the Parker Pen Company set out to develop a new and improved fountain pen ink. Inferior inks had long been the main cause of clogged fountain pens, yet popular ink formulations had remained unchanged in decades. Research for the project was initially outsourced to Miner Laboratories of Chicago. In August 1930 one of the lead chemists, Galen Sayler, was hired directly and put to work in a small laboratory at company headquarters in Janesville, Wisconsin. History Quink was heavily advertised, and an immediate success. According to Kenneth Parker's personal journal, Quink production began on March 17, 1931, and $89,000 worth had been shipped by October 22—more than twice the company's expectations and an excellent return on the $68,000 spent on its dev ...

Elizabeth II
Elizabeth II (Elizabeth Alexandra Mary; 21 April 1926 – 8 September 2022) was Queen of the United Kingdom and other Commonwealth realms from 6 February 1952 until her death in 2022. She was queen regnant of 32 sovereign states during her lifetime, and was head of state of 15 realms at the time of her death. Her reign of 70 years and 214 days was the longest of any British monarch and the longest verified reign of any female monarch in history. Elizabeth was born in Mayfair, London, as the first child of the Duke and Duchess of York (later King George VI and Queen Elizabeth The Queen Mother). Her father acceded to the throne in 1936 upon the abdication of his brother Edward VIII, making the ten-year-old Princess Elizabeth the heir presumptive. She was educated privately at home and began to undertake public duties during the Second World War, serving in the Auxiliary Territorial Service. In November 1947, she married Philip Mountbatten, a former prince ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
