Sheaffer Prelude
The Sheaffer Prelude fountain pens, rollerball pens and ballpoints are a line of writing instruments made by the Sheaffer Pen Company. Construction & Trim The pen is made out of stock brass rods, and the section is made of moulded acrylic and has ridges for easy grip. The jewel on the clip is made of mother-of-pearl, and the sheet-like cap band and clip are stainless steel. The nib is also stainless steel. The clip and cap band are plated in Gold or Chrome depending on the pen's trim, while the nib is semi-plated in Gold or is unplated Steel depending on trim, but Sheaffer also offers 14K Gold nibs in certain countries in Asia. The Ballpoint is a twist-action. Finishes Sheaffer Prelude pens come in a number of finishes, from plain lacquer to plated in precious metals, and from Chrome trim to Gold trim. There was also a Rainbow finish in both trims, but it was discontinued very early and are very desirable today. Another exotic finish was from the "Holiday Original" Sheaffer p ...

Fountain Pens
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 han ...

Rollerball Pens
Roller ball pens or roll pens are pens which use ball point writing mechanisms with water-based liquid or gelled ink, as opposed to the oil-based viscous inks found in ballpoint pens. These less viscous inks, which tend to saturate more deeply and more widely into paper than other types of ink, give roller ball pens their distinctive writing qualities. The writing point is a tiny ball, usually 0.5 or 0.7 mm in diameter, that transfers the ink from the reservoir onto the paper as the pen moves. Advantages There are two main types of roller ball pens: liquid ink pens and gel ink pens. The 'liquid-ink' type uses an ink and ink supply system similar to a fountain pen, and they are designed to combine the convenience of a ballpoint pen with the smooth "wet ink" effect of a fountain pen. The 'liquid-ink' type rollerball pens were introduced in 1963 by the Japanese company Ohto. The gel ink type rollerball pens were patented in 1982 by Sakura Color Products. Gel inks usua ...

Ballpoints
A ballpoint pen, also known as a biro (British English), ball pen (Hong Kong, Indian and Philippine English), or dot pen ( Nepali) is a pen that dispenses ink (usually in paste form) over a metal ball at its point, i.e. over a "ball point". The metal commonly used is steel, brass, or tungsten carbide. The design was conceived and developed as a cleaner and more reliable alternative to dip pens and fountain pens, and it is now the world's most-used writing instrument; millions are manufactured and sold daily. It has influenced art and graphic design and spawned an artwork genre. Some pen manufacturers produce designer ballpoint pens for the high-end and collectors' markets. History Origins The concept of using a "ball point" within a writing instrument to apply ink to paper has existed since the late 19th century. In these inventions, the ink was placed in a thin tube whose end was blocked by a tiny ball, held so that it could not slip into the tube or fall out of the p ...

Sheaffer
Sheaffer Pen Corporation () is an American manufacturing company of writing instruments, particularly luxury fountain pens. The company was founded by Walter A. Sheaffer in Fort Madison, Iowa, and incorporated in 1913 to exploit his invention of a lever-filling fountain pen. The brand was sold by French company Bic to A. T. Cross Company in August, 2014. In August, 2022 the brand was sold to and is currently owned bWilliam Penn Private Limited a multi-brand retailer and distributor of writing instruments and accessories. History In 1912, Walter A. Sheaffer took his idea of a pen filling apparatus that utilized a lever system and, with his life savings, founded the W. A. Sheaffer Pen Company in Fort Madison, Iowa. The company was established in the back room of Mr. Sheaffer's jewelry store with seven employees, and was incorporated a year later, in 1913. By the 1930s, Sheaffer fountain pens were being advertised as the pen that "fills instantly from any ink-well, with one touc ...

Acrylic Resin
186 px, Polyhydroxyethylmethacrylate is a typical acrylate resin. An acrylic resin is a thermoplastic or thermosetting plastic substance typically derived from acrylic acid, methacrylic acid and acrylate monomers such as butyl acrylate and or methacrylate monomers such as methyl methacrylate. Thermoplastic acrylics designate a group of acrylic resins typically containing both a high molecular weight and a high glass transition temperature which exhibit lacquer dry capability. Acrylic resins designed for use in two component systems for crosslinking with isocyanate are referred to as polyols and are made with the monomers previously mentioned as well as hydroxy monomers such as hydroxy ethyl methacrylate. Acrylic resins are produced in different liquid carriers such as a hydrocarbon solvent (solventborne acrylics or solution acrylics solventborne acrylic selector) or water in which case they are referred to as emulsions or dispersions and they are also provided in 100% solids be ...

Gold
Gold is a chemical element with the symbol Au (from la, aurum) and atomic number 79. This makes it one of the higher atomic number elements that occur naturally. It is a bright, slightly orange-yellow, dense, soft, malleable, and ductile metal in a pure form. Chemically, gold is a transition metal and a group 11 element. It is one of the least reactive chemical elements and is solid under standard conditions. Gold often occurs in free elemental ( native state), as nuggets or grains, in rocks, veins, and alluvial deposits. It occurs in a solid solution series with the native element silver (as electrum), naturally alloyed with other metals like copper and palladium, and mineral inclusions such as within pyrite. Less commonly, it occurs in minerals as gold compounds, often with tellurium (gold tellurides). Gold is resistant to most acids, though it does dissolve in aqua regia (a mixture of nitric acid and hydrochloric acid), forming a soluble tetrachloroaurate anion. Gold is ...

Steel
Steel is an alloy made up of iron with added carbon to improve its strength and fracture resistance compared to other forms of iron. Many other elements may be present or added. Stainless steels that are corrosion- and oxidation-resistant typically need an additional 11% chromium. Because of its high tensile strength and low cost, steel is used in buildings, infrastructure, tools, ships, trains, cars, machines, electrical appliances, weapons, and rockets. Iron is the base metal of steel. Depending on the temperature, it can take two crystalline forms (allotropic forms): body-centred cubic and face-centred cubic. The interaction of the allotropes of iron with the alloying elements, primarily carbon, gives steel and cast iron their range of unique properties. In pure iron, the crystal structure has relatively little resistance to the iron atoms slipping past one another, and so pure iron is quite ductile, or soft and easily formed. In steel, small amounts of carbon, other ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lacquer
Lacquer is a type of hard and usually shiny coating or finish applied to materials such as wood or metal. It is most often made from resin extracted from trees and waxes and has been in use since antiquity. Asian lacquerware, which may be called "true lacquer", are objects coated with the treated, dyed and dried sap of ''Toxicodendron vernicifluum'' or related trees, applied in several coats to a base that is usually wood. This dries to a very hard and smooth surface layer which is durable, waterproof, and attractive in feel and look. Asian lacquer is sometimes painted with pictures, inlaid with shell and other materials, or carved, as well as dusted with gold and given other further decorative treatments. In modern techniques, lacquer means a range of clear or pigmented coatings that dry by solvent evaporation to produce a hard, durable finish. The finish can be of any sheen level from ultra matte to high gloss, and it can be further polished as required. Lacquer finishes ...

Warranty
In contract law, a warranty is a promise which is not a condition of the contract or an innominate term: (1) it is a term "not going to the root of the contract",Hogg M. (2011). ''Promises and Contract Law: Comparative Perspectives''p. 48 Cambridge University Press. and (2) which only entitles the innocent party to damages if it is breached: i.e. the warranty is not true or the defaulting party does not perform the contract in accordance with the terms of the warranty. A warranty is not a guarantee. It is a mere promise. It may be enforced if it is breached by an award for the legal remedy of damages. A warranty is a term of a contract. Depending on the terms of the contract, a product warranty may cover a product such that a manufacturer provides a warranty to a consumer with which the manufacturer has no direct contractual relationship. A warranty may be express or implied. An express warranty is expressly stated (typically, written); whether or not a term will be implied int ...
