Scotch Tape and Inventor Richard Drew

Scotch Tape and Inventor Richard Drew Scotch tape was invented in 1930 by banjo-playing 3M engineer Richard Drew. Scotch tape was the worlds first transparent adhesive tape. Drew also invented the first masking tape in 1925- a 2-inch-wide tan paper tape with a pressure sensitive adhesive backing. Richard Drew - Background In 1923, Drew joined the 3M company located in St. Paul, Minnesota. At the time, 3M only made sandpaper. Drew was product testing 3Ms Wetordry brand sandpaper at a local auto body shop, when he noticed that auto painters were having a hard time making clean dividing lines on two-color paint jobs. Richard Drew was inspired to invent the worlds first masking tape in 1925, as a solution to the auto painters dilemma. Brandname Scotch The brand name Scotch came about while Drew was testing his first masking tape to determine how much adhesive he needed to add. The body shop painter became frustrated with the sample masking tape and exclaimed, Take this tape back to those Scotch bosses of yours and tell them to put more adhesive on it! The name was soon applied to the entire line of 3M tapes. Scotch Brand Cellulose Tape was invented five years later. Made with a nearly invisible adhesive, the waterproof transparent tape was made from  oils, resins, and rubber; and had a coated backing. According to 3M Drew, a young 3M engineer, invented the first waterproof, see-through, pressure-sensitive tape, thus supplying an attractive, moisture-proof way to seal food wrap for bakers, grocers, and meat packers. Drew sent a trial shipment of the new Scotch cellulose tape to a Chicago firm specializing in package printing for bakery products. The response was, Put this product on the market! Shortly after, heat sealing reduced the original use of the new tape. However, Americans in a depressed economy discovered they could use the tape to mend a wide variety of things like torn pages of books and documents, broken toys, ripped window shades, even dilapidated currency. Besides using  Scotch  as a prefix in its brand names (Scotchgard,  Scotchlite and  Scotch-Brite), the company also used the Scotch name for its (mainly professional) audiovisual magnetic tape products, until the early 1990s when the tapes were branded solely with the 3M logo.  In 1996, 3M exited the magnetic tape business, selling its assets. John A Borden - Tape Dispenser John A Borden, another 3M engineer, invented the first tape dispenser with a built-in cutter blade in 1932. Scotch Brand Magic Transparent Tape  was invented in 1961, an almost invisible tape that never discolored and could be written on. Scotty McTape Scotty McTape, a  kilt-wearing  cartoon  boy, was the brands  mascot  for two decades, first appearing in 1944.  The familiar  tartan  design, a take on the well-known  Wallace  tartan, was introduced in 1945. Other Uses In 1953, Soviet scientists showed that  triboluminescence  caused by peeling a roll of an unidentified Scotch brand tape in a  vacuum  can produce  X-rays.  In 2008, American scientists performed an experiment that showed the rays can be strong enough to leave an X-ray image of a finger on  photographic paper.

Introduction to Art Essays Introduction to Art Essay Introduction to Art Essay EXPULSION OF ADAM AND EVE FROM EDEN Charisse Drysdale HUM 100 May 16, 2011 The purpose of this essay is to analyze the painting of Masaccio, Expulsion of Adam and Eve from Eden. Masaccio of the early fourteenth century attempted to observe carefully and to record the variety of his visual experience in a logical and clear manner. Masaccio faced the problem of arranging figures in a mathematically defined space without making the picture appear to be artificially constructed, and thus isolating them from the composition or even sacrificing them to the ideal proportions of the room. Masaccio solved the problem by placing the traditional portraits of his patrons, the figures of God the Father remains unclear, thus softening to some extent the rigors of the mathematical perspective. Masaccios painting is highly dramatic, volumetric, and expansive. The shapes of Masaccios Adam and Eve are constructed not with line but with strongly differentiated areas of light and dark that give them a pronounced three-dimensional sense of relief. The expressive movements and gestures that Masaccio gives to Adam and Eve powerfully convey their anguish at being expelled from the Garden of Eden and adds psychological dimension to the impressive physical realism of these figures. Masaccios harrowing scene of the expulsion of Adam and Eve from the Garden of Eden shows the expressive force and directness of his style. An angel drives the sinners into the harsh, barren world, where the light mercilessly exposes their guilt and despair. Masaccios composition is beautifully balanced within the narrow format. The forward movement, dictated by the gesture of the angel, is firmly anchored by the strong vertical running from the heads of Adam and Eve to their heels. The muscular tension of Adams body, and the fluidity of Eves, were inspired by a contemporary relief, Masaccio is one of the first artists to use light realistically, rather than using it to highlight his figures. They are drawn nude, with expressions of pure anguish that invite the viewer to oin them in sadness for the sin that we all share. Masaccio uses naturalism to portray one of the most known stories of his time, and this naturalism draws the reader into the emotions of the figures of the story. Because we share the same sin as the figures in the painting, they are depicted in a naturalistic way to make them seem even more like us. Masaccio was concerned with the naturalistic portrayal of human figures, particularly in terms of shadow and light, color, shape, and dimensions in space. These aspects all relate back to perspective: the painter takes pains to represent the size of the figures accurately and they therefore must further resemble Nature in their form, arrangement, and their ability to cast shadows. The figures must also be arranged in appealing positions, and the composition must have â€Å"dignity† in that there are enough characters to interest the viewer but not so many that the work appears crowded. Lastly, he emphasizes the importance of an istoria. That is, the work should contain some kind of narrative or story. The emotions of the figures must be culpable and real for the viewer: the viewer must enter the story. In sum, a painting must become the viewer’s emotional reality, as well as its physical reality (in that the painter attempts to recreate the plane of vision created by the visual pyramid of the eye). The figures must occupy space, capture light, and have mass: they must be a part of the viewer’s world. Scientific perspective also contributes to the viewer’s perception of the painting as reality; the painting is meant to appear as would a real scene in front of a viewer. The painter can use techniques of color, light, and perception to elicit a controlled response from the viewer. The viewer’s eye takes in the painting as seen from life and enters into the emotions portrayed; the istoria is of upmost importance in creating this illusion. Masaccio is using movement and perspective to create an illusion of space that is not actually there, but that would exist if the painting was reality. In this way, the viewer can enter into the istoria. The illusion of perspective reminds the viewer of their distance from God, their own mortality, and also the role of the Church as intercessor. Once again, the naturalist technique used by Masaccio is to elicit a certain response from the viewer and the world of the painting becomes their own reality.

Understanding the Difference Between Lend and Loan

Understanding the Difference Between Lend and Loan In formal usage (especially in British English), lend is a verb and loan is a noun. In informal  American English, the use of loan as a verb is generally considered acceptable (particularly when it concerns the lending of money). See the usage notes below. Only lend has figurative uses, as in Lend me your ears or Lend me a hand.Also see:Commonly Confused Words: Loan and Lone Examples: Borrow trouble for yourself, if thats your nature, but dont lend it to your neighbors. (Rudyard Kipling)A bank, so the old saying goes, is a place where you can always get a loan- when you dont need one. Usage Notes Although most expert users of English dislike loan as a verb (I loaned him my pen), except in financial contexts, it must be acknowledged that the usage is sanctioned by dictionaries. If you are not offended by Friends, Romans, countrymen, loan me your ears or by Distance loans enchantment, you may go along with the dictionaries and you will always have a defense.(Theodore M. Bernstein, Miss Thistlebottoms Hobgoblins, Farrar, Straus and Giroux, 1971)Some people are bothered by the word loan as a verb, preferring to use lend in its place. Theres not much reason for the anxiety- loan has been a verb since around the year 1200, and I think an 800-year probation is long enough for anyone- but its now little used in America. My advice: dont be bothered by loan as a verb but, if you want to avoid irritating those who have this hangup, its never wrong to use lend.(Jack Lynch, The English Language: A Users Guide, Focus, 2008)The verb loan is well established in American usage and cannot be c onsidered incorrect. The frequent objections to the form by American grammarians may have originated from a provincial deference to British critics, who long ago labeled the usage a typical Americanism. Loan is, however, used to describe only physical transactions, as of money or goods; for figurative transactions, lend is correct: Distance lends enchantment. The allusions lend the work a classical tone.(The American Heritage Dictionary of the English Language, 4th ed., 2000) These are sometimes interchangeable, sometimes not. Only lend carries the figurative senses of adding or giving, as in lend strength to the cause or lend color to an otherwise routine event. But for other senses, as when property or money pass temporarily from one owner to another, either word could be used. . . . In American and Australian English, the verb loan is readily used as an alternative to lend in such applicationsbut not so much in contemporary British English. The word was used in Britain up to C17, but a curious resistance seems to have developed there during C18 and C19, when the Oxford Dictionary (1989) citations are all from the US, and the word somehow acquired provincial associations. Fowler (1926) noted that it had been expelled from southern British English, but that it was still used locally in the UK. Yet Gowers writing after World War II found it returning to British government writing (1948, 1954) and weighs in against it in his 1965 edition of Fowler as a nee dless variant (1965). This seems to be the basis on which British usage commentators argue that loan must be used only as a noun (except in banking and finance) and lend as a verb. Some British dictionaries (Collins, 1991) and the Canadian Oxford (1998) still echo the inhibition, while data from the BNC [British National Corpus] shows that many British writers are comfortable with it.

Establishing an Illegal Business Essay Example | Topics and Well Written Essays - 1000 words

Establishing an Illegal Business - Essay Example Establishing an Illegal This paper shows how to establish a lucrative ecstasy-manufacturing firm in the country The medical department refers to ecstasy to be illegal since there is drug has no medicinal value. They argue that the drug has effects on the human brain with effects such as hallucination. Despite the medical reasons, the drug still attracts a large market demand. At this point, the first steps of starting a business are in place. The beginning tasks such as the product type and the size of business is already in place. The second step involves being aware of the customers’ needs. The main customers of the product would target the young generation. The young generation holds the largest demand for the ecstasy drug. There should be enough information concerning the manufacture and distribution of the drug. To have a proper network that would coordinate the flow of the drug; the firm would work closely with other distributors and study how the drug rotates. Next is to identify the area that would best fit the establishment of the company. The area should be one that does not attract any suspicion to the authorities. The best way would be to establish a camouflage firm that would cover the identity of the drug. Identification of financial, natural, man-made and human resources for the firm should be available freely. A business plan would assist with the planning and calculation of the requirements. This is the trickiest part before the actual running of the operation. At this point, it would be difficult to trust the operators for information. In addition, the government has spies from top agencies that are out to fight the production and distribution of drugs. Therefore, as the planning occurs, the company would import the products from outside countries to test the market (Koellhoffer 24). Importation would need the firm to seek creative methods that would challenge the border security. The government concentrates on cracking down on drug traffickers along the Mexic an border and major airports. The security is tight in those areas because Mexico is a major drug trafficking country. The government has produced information that links drug trafficking to the Islamic terrorist groups. Associating with the terrorist groups openly, would link the firm to drug trafficking, thereby, blowing its cover (Brott 48). There would be need to establish connections along the customs officials that would assist in importing the products. After making the order from the outside country, the firm would claim to be importing materials to set up a local pharmaceutical firm. In the process of importing the materials, the firm would smuggle some quantities of ecstasy to try into the market. The operations at the customs would require the influence of powerful individuals in the country to see to it that the drugs come in. As mentioned above, drug business is a billion dollar enterprise headed by powerful people in the country. Many of the firm’s expenses would include paying off powerful individuals who influence the drug trade in the market (Harvard Business School 67). Ones the drug is in the market, the firm would begin by first having agents who distribute at parties. Through this, the agent would interact with other drug agents from other countries. Soon the drug distribution system will be in place, enough for the firm to supply to the other agents from different drug cartels. Once the firm establishes the proper networks necessary to meet the requirements for profitable
