Rubber history timeline

Rubber-Band History is the phenomenon where a story begins in an Alternate History but ends with the usual timeline having been restored. History, apparently, is like a giant rubber band: you can stretch it and twist it, but sooner or later it will spring back into its original form, and the more radical the change the nastier the Snap Back will be. Sometimes, the resident Alternate Badass of said timeline will come back if the alternate timeline threatens to become dominant again.

Don't expect them to stick aroundthough. This trope is easiest to grasp in the context of a series, where an episode starts with a radically different version of reality that sooner or later snaps back into the version established in earlier episodes. But it can also be seen in standalone works, where it's the timeline snapping back to "real" history — ie.

In the latter case, it's often implied that in-universe the unfamiliar timeline is the original one and the change to our reality is a new alteration and not a reversion to a previous state; that still counts. If history can't be brought back to its original form without some major differences, it's a Close-Enough Timeline — like when Alice escapes death, but our heroes make sure she gets run over by a truck a few minutes later anyway.

Neil Gaiman 's Marvel is set in a timeline in which the heroes and villains of the Marvel Comics Universe begin to appear years early.

In the end, the disrupting factor is identified and dealt with, and the history of the Marvel Universe is restored to normal although the timeline survives in a pocket universe. In "Empty Graves", part of the Sorrowful and Immaculate Hearts series, Martha Kent has to deal with a succession of time-traveling assassins attempting to kill Clark Kent while he's still young and relatively defenseless.

Each time traveler is from a different future which ceases to exist as a result of their actions — for instance, one of the first is from a future where Jonathan and Martha kept Clark isolated on the farm for fear of what might happen if his origins were discovered, with the result that he grew up emotionally isolated from humanity and became a tyrannical overlord; having seen how that will turn out, Martha decides to risk letting Clark go to school and make friends, and that future is averted.

After several such adjustments, the final time-traveling villain is from the familiar-to-the-reader timeline in which Clark grows up to become Superman.

It holds papers together, prevents long hair from falling in a face, acts as a reminder around a wrist, is a playful weapon in a pinch, and provides a way to easily castrating baby male livestock … While rubber itself has been around for centuries, rubber bands were only officially patented less than two centuries ago.

Here now is a brief history of the humble, yet incredibly useful, rubber band. It has only recently been discovered that Mesoamerican peoples which includes Aztecs, Olmecs, and Mayans were making rubber though they didn't call it this three thousand years ago. Mixing milky-white sap known as latex from the indigenous Hevea brasiliensis trees later called Para rubber trees with juices from the morning glory vines, they could create a solid that was, surprisingly, quite sturdy.

The civilizations used this ancient rubber for a variety of purposes, from sandals to balls to jewelry. In fact, while Charles Goodyear is generally credited with the invention of vulcanized rubber a more durable and non-sticky rubber compound via the addition of sulfur and heatit seems that the Aztecs were simply varying the ingredient proportions between the latex and the morning glory juice to create different variations in strength.

When Spanish explorers arrived in South America in the 16th century, they discovered for themselves the many uses of this elastic, malleable sap.

When the French explorer Charles de la Condamine "discovered" it in the s, he called it "caoutchouc", a French word, but a variation on the South American word for latex. In attempting to figure out what it was exactly, Condamine came to a wrong conclusion — he thought it was condensed resinous oil. The name "rubber" was only attributed to this latex material when, inthe famed British chemist Joseph Priestley who also discovered oxygen noted that the material rubbed pencil marks right off paper, thereby inventing the eraser and giving the "rubbing material" a name.

By the end of the 18th century, the material was forever known as "rubber. InEnglishmen Thomas Hancock was in the stagecoach business with his brothers when he attempted to figure out better ways to keep his customers dry while traveling. He turned to rubber to develop elastic and waterproof suspenders, gloves, shoes, and socks. He was so enamored with the material that he began to mass produce it, but he soon realized he was generating massive amounts of wasted rubber in the process.

So, Hancock developed his "Pickling machine" later called a masticator to rip up the leftover rubber into shreds. He, then, mashed the malleable rubber together, creating a new solid mass, and put it into molds to design whatever he wanted.

One of his first designs were bands made out of rubber, though he never marketed or sold them, not realizing the practically of rubber bands. Plus, vulcanization hadn't been discovered yet which we will discuss in a momentso the bands would soften considerably on hot days and harden on cold days.

In short, these rubber bands simply weren't very practical at this stage of the game, in terms of many of the types of things rubber bands would later be used for. Hancock didn't patented his machine or the shreds of rubber it produced, instead hoping to keep the manufacturing process completely secret.I agree to the use of cookies and tracking mechanisms which are used to analyse my activity on this website in order to improve my user experience.

Since our beginning, Hankook Tire has contributed to tire innovation and enhanced true driving emotion while putting emphasis on becoming one with the environment. Composed of only firm rubber without the need for air, the solid rubber tire is used mostly for slow-speed vehicles because of its poor shock absorption ability. Tread is a part of a tire that comes in direct contact with a road surface.

Made out of thick rubber, tread protects carcass and breaker inside a tire. Road surface friction coefficient increased with a development of the tread tire and today it is produced in various patterns.

In lateHenry Ford introduced the first conveyor belt assembly line to the world, marking the start of the first stage of automobile popularization. InAmerican company Du Pont successfully industrialized synthetic rubber. This development allowed tire industry, which had been dependent on natural rubber, to increase tire quantity and quality, ushering in a turning point in tire production.

Balloon tire, a type of low-pressure tire is used in various types of automobiles to increase its contact area to road surface with low Internal air pressure. In order to relieve a burden of sky-high oil prices brought on by the oil shock, it became popular to reduce the size and weight of existing car models.

Many manufacturers eventually employed the front-wheel drive method for their cars. With a development of the tubeless tire inthe resulting weight reduction contributed significantly to the saving of fuel. Firstly invented in the s, the radial tire refers to a type of tire in which the cords, carcass plies are vertically arranged to driving direction.

Because of lower deformation of radial tire than bias tire during driving, radial tire has better fuel efficient. Uniform contact of tread in radial tire to road surface offers good driving stability, especially on high-speed. Even with scratches or holes caused due to obstacles or tire abrasion while driving, and the resulting deflation, the run-flat tire is able to maintain a constant driving speed.

It protects the driver from various accidents that can arise in emergency situations. With the transformation of the automobile from an effective method of transportation into a symbol of personal financial power and freedom, people became increasingly interested in driving performance.

Driving performance increased with the development of the UHP Ultra High Performance tire, which boasts superior cornering, drivability and braking, in accordance with new development of tire technology. The UHP tire is defined as a tire with a rim diameter equal to or greater than 16 inches, an aspect ratio equal to or less than 55 and speed symbol higher than V max.Key dates in history of multiracial, Islamic nation greatly shaped by its key spot along East-West trade routes.

Spain eases curbs as coronavirus toll drops: Live updates.Liquid silicone rubber and the liquid injection molding LIM process play a pivotal role in the manufacturing process of a broad range of industries. This is changing the very nature of the manufacturing world. It makes possible the fabrication of a wide range of parts for just about every industry imaginable. The fabrication process allows for a high productivity level, due to quick cycle time.

After the design and production of the molds, the operator can change the materials and colors with minimal effort. The typical injection molding machine has a self-gating automated device that moves parts through the manufacturing process effectively and efficiently, with little or no manual labor required.

This lowers per unit labor costs. The process has its disadvantages. For example, there is a high cost of entry for tooling and the injection molding machine.

Part design depends on the creativity of the designer. Parts cannot be hollow; they must be completely solid. The process requires the separate fabrication of each piece. In addition, the precision required for tooling and the fabrication process requires skills and expertise in design and plastic injection molding manufacturing. The advantages of the injection molding process easily offset the disadvantages. The injection molding fabrication process, which has evolved along with the plastics and synthetic rubber industries, has its origins in the late 19th century.

During this period, American and European chemists began experimenting with different rubbers and residues from chemical mixtures, which moved liquid injection molding to its current position as a dominant fabrication process in a variety of industries.

Modern plastics as we know them today have their origin in the late 19th century. During this period, numerous European and American chemists experimented with various types of rubber and residues from chemical mixtures.

All plastics fall under the scientific term polymers. A polymer is a large molecule comprised of many smaller units, or monomers, bound together.

The monomers are linked together from end-to-end by chemical bonds, which form a long chain. Polymer materials flow and fabricators mold them into parts. Natural polymers, such as horn, shellac, tortoiseshell, and a variety of resinous tree saps have existed since the beginning of time.Rubbermaid is an American manufacturer and distributor of many household items.

It is a subsidiary of Newell Brands. It is best known for producing food storage containers and trash cans. Additionally it produces shedsstep stoolsclosets and shelving, and laundry basketsbut also air fresheners and other household items.

Archived from the original on The New York Times.Centered in the Amazon Basinthe boom resulted in a large expansion of European colonization in the area, attracting immigrant workers, generating wealth, causing cultural and social transformations, and wreaking havoc upon indigenous societies. The rubber boom occurred largely between and There was heightened rubber production and associated activities again from to during the Second World War.

Natural rubber is an elastomeralso known as tree gum, India rubber, and caoutchouc, which comes from the rubber tree in tropical regions. Christopher Columbus was the one of the first Europeans to bring news of this odd substance back to Europe, but he was not the only one to report it. Arounda French astronomer recalled how Amerindians used rubber to waterproof shoes and cloaks.

He brought several samples of rubber back to France. Rubber was used as an eraser by scientist Joseph Priestley in England. It was not until the s that practical uses of rubber were developed and the demand for rubber began.

A rubber factory that made rubber garters for women suspenders US or braces UK opened in ParisFrancein the year At higher temperatures, the rubber became softer and stickier, while at lower temperatures it became hard and rigid. The South Amerindians first discovered rubber; sometime dating back to BC. The Amerindians in the Amazon rainforest developed ways to extract rubber from the rubber tree Hevea brasiliensisa member of the family Euphorbiaceae.

A white liquid called latex is extracted from the stem of the rubber tree, and contains rubber particles dispersed in an aqueous serum. Latex is practically a neutral substance, with a pH of 7. However, when it is exposed to the air for 12 to 24 hours, its pH falls and it spontaneously coagulates to form a solid mass of rubber. Rubber produced in this fashion has disadvantages. For example, exposure to air causes it to mix with various materials, which is perceptible and can cause rot, as well as a temperature-dependent stickiness.

Industrial treatment was developed to remove the impurities and vulcanize the rubber, a process that eliminated its undesirable qualities. This process gives it superior mechanical properties, and causes it to lose its sticky character, and become stable - resistant to solvents and variations in temperature.

The rubber boom and the associated need for a large workforce had a significant negative effect on the indigenous population across Brazil, Peru, Ecuador and Colombia.

As rubber plantations grew, labor shortages increased. The owners of the plantations or rubber barons were rich, but those who collected the rubber made very little as a large amount of rubber was needed to be profitable.

The rubber barons rounded up all the Indians and forced them to tap rubber out of the trees.

One plantation started with 50, Indians but, when discovered, only 8, were still alive. These rubber plantations were part of the Brazilian rubber market, which declined as rubber plantations in Southeast Asia became more effective. Roger Casementan Irishman traveling the Putumayo region of Peru as a British consul from todocumented the abuse, slavery, murder and use of stocks for torture against the native Indians: [4].

According to Wade Davisauthor of One River :. Rubber had catastrophic effects in parts of Upper Amazonia, but its impact should not be exaggerated nor extrapolated to the whole region. The Putumayo was a particularly horrific case. Many nearby rubber regions were not ruled by physical violence, but by the voluntary compliance implicit in patron-peon relations.

Some native peoples benefited financially from their dealings with the white merchants. Others chose not to participate in the rubber business and stayed away from the main rivers.

Because tappers worked in near complete isolation, they were not burdened by overseers and timetables. In Brazil and probably elsewhere tappers could, and did, adulterate rubber cargoes, by adding sand and flour to the rubber "balls", before sending them downriver. Flight into the thicket was a successful survival strategy and, because Indians were engaged in credit relations, it was a relatively common practice to vanish and work for other patrons, leaving debts unpaid.

For the first four and a half centuries following the discovery of the New Worldthe native populations of the Amazon Basin lived practically in isolation. The area was vast and impenetrable, no gold or precious stones had been found there, as neither colonial Brazil nor imperial Brazil was able to create incentives for development in the region.
