Tipp-Ex
Tipp-Ex is a brand of correction fluid and other related products that is popular throughout Europe. It was also the name of the German company ('' Tipp-Ex GmbH & Co. KG'') that produced the products in the Tipp-Ex line. While ''Tipp-Ex'' is a trademark name for correction products, in some countries it has become a genericised trademark: ''to tippex'' or ''to tippex out'' means to erase, either generally or with correction fluid. History ''Tipp-Ex'' correction paper was invented by Wolfgang Dabisch from Eltville, West Germany, who filed a patent in 1958 on ''Colored film for the correction of typing errors'' (German: ''Tippfehler''). He subsequently founded a company of the same name. Shortly after that a ''Tipp-Ex Sales & Distribution'' company (Tipp-Ex Vertrieb GmbH & Co. KG) was founded in Frankfurt by Otto Carls.

Correction Fluid
A correction fluid is an opaque, usually white fluid applied to paper to mask errors in text. Once dried, it can be handwritten or typed upon. It is typically packaged in small bottles, lids attached to brushes (or triangular pieces of foam) that dip into the fluid. The brush applies the fluid to the paper. Before the invention of word processors, correction fluid greatly facilitated the production of typewritten documents. One of the first forms of correction fluid was invented in 1956 by American secretary Bette Nesmith Graham, founder of Liquid Paper. With the advent of colored paper stocks for office use, manufacturers began producing their fluids in various matching colors, particularly reds, blues and yellows. Composition The exact composition of correction fluid varies between manufacturers, but most fluids are composed of an ''opacifying agent'', a ''solvent'' (or thinner) and an adulterant 'fragrance' to discourage abuse. The opacifying agent can be composed of a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wite-Out
Wite-Out is a registered trademark for a brand of correction fluid, originally created for use with photocopies, and manufactured by the BIC corporation. History Wite-Out dates to 1966, when Edwin Johan, an insurance-company clerk, sought to address a problem he observed in correction fluid available at the time: a tendency to smudge ink on photostatic copies when it was applied. Johan enlisted the help of his associate George Kloosterhouse, a basement waterproofer who experimented with chemicals, and together they developed their own correction fluid, introduced as "Wite-Out WO-1 Erasing Liquid". In 1971, they incorporated as Wite-Out Products, Inc. The trademark "Wite-Out" was registered by the United States Patent and Trademark Office on February 5, 1974. The application listed the date of "first use in commerce" as January 27, 1966. Early forms of Wite-Out sold through 1981 were water-based and hence water-soluble. While this allowed simple cleaning, it also had the probl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Liquid Paper
Liquid Paper is an American brand of the Newell Brands company marketed internationally that sells correction fluid, correction pens, and correction tape. Mainly used to correct typewriting in the past, correction products now mostly cover handwriting mistakes. Product history In 1956, Bette Nesmith Graham (mother of future The Monkees guitarist Michael Nesmith) invented the first correction fluid in her kitchen. Working as a typist, she used to make many mistakes and always strove for a way to correct them. Starting on a basis of tempera paint she mixed with a common kitchen blender, she called the fluid "Mistake Out" and started to provide her co-workers with small bottles on which the brand's name was displayed. By 1958, Graham founded the Mistake Out Company and continued working from her kitchen (and eventually garage) nights and weekends to produce small batches of correction bottles. She was fired from her typist job as executive secretary at Texas Bank and Trust after s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brand
A brand is a name, term, design, symbol or any other feature that distinguishes one seller's good or service from those of other sellers. Brands are used in business, marketing, and advertising for recognition and, importantly, to create and store value as brand equity for the object identified, to the benefit of the brand's customers, its owners and shareholders. Brand names are sometimes distinguished from Generic brand, generic or store brands. The practice of branding - in the original literal sense of marking by burning - is thought to have begun with the ancient Egyptians, who are known to have engaged in livestock branding as early as 2,700 BCE. Branding was used to differentiate one person's cattle from another's by means of a distinctive symbol burned into the animal's skin with a hot branding iron. If a person stole any of the cattle, anyone else who saw the symbol could deduce the actual owner. The term has been extended to mean a strategic personality for a produ ...

Spelling Correction Example
Spelling is a set of conventions that regulate the way of using graphemes (writing system) to represent a language in its written language, written form. In other words, spelling is the rendering of speech sound (phoneme) into writing (grapheme). Spelling is one of the elements of orthography, and highly standardized spelling is a linguistic prescription, prescriptive element. Spellings originated as transcription (linguistics), transcriptions of the sounds of speech, spoken language according to the alphabetic principle. They remain largely reflective of the sounds, although phonemic orthography, fully phonemic spelling is an ideal that most languages' orthographies only approximate, some more closely than others. This is true for various reasons, including that pronunciation changes over time in all languages, yet spellings as visual norms may resist change. In addition, words from other languages may be adopted without being adapted to the spelling system, and different meanin ...

Hydrocarbons
In organic chemistry, a hydrocarbon is an organic compound consisting entirely of hydrogen and carbon. Hydrocarbons are examples of group 14 hydrides. Hydrocarbons are generally colourless and hydrophobic, and their odors are usually weak or exemplified by the odors of gasoline and lighter fluid. They occur in a diverse range of molecular structures and phases: they can be gases (such as methane and propane), liquids (such as hexane and benzene), low melting solids (such as paraffin wax and naphthalene) or polymers (such as polyethylene and polystyrene). In the fossil fuel industries, ''hydrocarbon'' refers to the naturally occurring petroleum, natural gas and coal, and to their hydrocarbon derivatives and purified forms. Combustion of hydrocarbons is the main source of the world's energy. Petroleum is the dominant raw-material source for organic commodity chemicals such as solvents and polymers. Most anthropogenic (human-generated) emissions of greenhouse gases are carb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aliphatic
In organic chemistry, hydrocarbons ( compounds composed solely of carbon and hydrogen) are divided into two classes: aromatic compounds and aliphatic compounds (; G. ''aleiphar'', fat, oil). Aliphatic compounds can be saturated, like hexane, or unsaturated, like hexene and hexyne. Open-chain compounds, whether straight or branched, and which contain no rings of any type, are always aliphatic. Cyclic compounds can be aliphatic if they are not aromatic. Structure Aliphatic compounds can be saturated, joined by single bonds (alkanes), or unsaturated, with double bonds (alkenes) or triple bonds (alkynes). If other elements (heteroatoms) are bound to the carbon chain, the most common being oxygen, nitrogen, sulfur, and chlorine, it is no longer a hydrocarbon, and therefore no longer an aliphatic compound. The least complex aliphatic compound is methane (CH4). Properties Most aliphatic compounds are flammable, allowing the use of hydrocarbons as fuel, such as methane in Buns ...

Ozone Layer
The ozone layer or ozone shield is a region of Earth's stratosphere that absorbs most of the Sun's ultraviolet radiation. It contains a high concentration of ozone (O3) in relation to other parts of the atmosphere, although still small in relation to other gases in the stratosphere. The ozone layer contains less than 10 parts per million of ozone, while the average ozone concentration in Earth's atmosphere as a whole is about 0.3 parts per million. The ozone layer is mainly found in the lower portion of the stratosphere, from approximately above Earth, although its thickness varies seasonally and geographically. The ozone layer was discovered in 1913 by the French physicists Charles Fabry and Henri Buisson. Measurements of the sun showed that the radiation sent out from its surface and reaching the ground on Earth is usually consistent with the spectrum of a black body with a temperature in the range of , except that there was no radiation below a wavelength of about 310 ...

Ozone
Ozone (), or trioxygen, is an inorganic molecule with the chemical formula . It is a pale blue gas with a distinctively pungent smell. It is an allotrope of oxygen that is much less stable than the diatomic allotrope , breaking down in the lower atmosphere to (dioxygen). Ozone is formed from dioxygen by the action of ultraviolet (UV) light and electrical discharges within the Earth's atmosphere. It is present in very low concentrations throughout the latter, with its highest concentration high in the ozone layer of the stratosphere, which absorbs most of the Sun's ultraviolet (UV) radiation. Ozone's odour is reminiscent of chlorine, and detectable by many people at concentrations of as little as in air. Ozone's O3 structure was determined in 1865. The molecule was later proven to have a bent structure and to be weakly diamagnetic. In standard conditions, ozone is a pale blue gas that condenses at cryogenic temperatures to a dark blue liquid and finally a violet-black soli ...

Blood–brain Barrier
The blood–brain barrier (BBB) is a highly selective semipermeable membrane, semipermeable border of endothelium, endothelial cells that prevents solutes in the circulating blood from ''non-selectively'' crossing into the extracellular fluid of the central nervous system where neurons reside. The blood–brain barrier is formed by endothelial cells of the Capillary, capillary wall, astrocyte end-feet ensheathing the capillary, and pericytes embedded in the capillary basement membrane. This system allows the passage of some small molecules by passive transport, passive diffusion, as well as the selective and active transport of various nutrients, ions, organic anions, and macromolecules such as glucose and amino acids that are crucial to neural function. The blood–brain barrier restricts the passage of pathogens, the diffusion of solutes in the blood, and Molecular mass, large or Hydrophile, hydrophilic molecules into the cerebrospinal fluid, while allowing the diffusion of Hydr ...

Paint Thinner
A paint thinner is a solvent used to thin oil-based paints. Solvents labeled "paint thinner" are usually mineral spirits having a flash point at about 40 °C (104 °F), the same as some popular brands of charcoal starter. Common solvents historically used as paint thinners include: * Mineral spirits (North America)/White spirit (United Kingdom and Ireland) * Acetone * Turpentine * Naphtha * Toluene * Lacquer thinner * Methyl ethyl ketone (MEK) * Dimethylformamide (DMF) * 2-Butoxyethanol, or any of the other glycol ethers Less common solvents used as paint thinner include: * Ethylbenzene * Xylene * ''n''-Butyl acetate * Butanol Exposure to vapors created by paint containing thinner or its cleanup may be hazardous. The American Conference of Governmental Industrial Hygienists has established threshold limit values (TLVs) for most of these compounds. TLV is defined as the maximum concentration in air which can be breathed by a normal person (i.e., excluding children, p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
