Air Conditioning history

shared by Trey Mcintyre on 14 Jan 14 - Cached
  • Air conditioning (often referred to as aircon, AC or A/C) is the process of altering the properties of air (primarily temperature and humidity) to more favourable conditions. More generally, air conditioning can refer to any form of technological cooling, heating, ventilation, or disinfection that modifies the condition of air.[1]
  • An air conditioner is a major or home appliance, system, or mechanism designed to change the air temperature and humidity within an area (used for cooling and sometimes heating depending on the air properties at a given time). The cooling is typically done using a simple refrigeration cycle, but sometimes evaporation is used, commonly for comfort cooling in buildings and motor vehicles. In construction, a complete system of heating, ventilation and air conditioning is referred to as "HVAC".
  • Air conditioning can also be provided by a simple process called free cooling which uses pumps to circulate a coolant

  • ng. Common storage media are deep aquifers or a natural underground rock mass accessed via a cluster of small-diameter, heat exchanger equipped boreholes.
  • he heat pump is added-in because the temperature of the storage gradually increase during the cooling season, thereby declining in effectiveness. Free cooling and hybrid systems are mature
  • The basic concept behind air conditioning is said to have been applied in ancient Egypt, where reeds were hung in windows and were moistened with trickling water. The evaporation of water cooled the air blowing through the window, though this process also made the air more humid (also beneficial in a dry desert climate). In Ancient Rome, water from aqueducts was circulated through the walls of certain houses to cool them. Other techniques in medieval Persia involved the use of cisterns and wind towers to cool buildings during the hot season. Modern air conditioning emerged from advances in chemistry during the 19th century, and the first large-scale electrical air conditioning was invented and used in 1902 by Willis Haviland Carrier. The introduction of residential air conditioning in the 1920s helped enable the great migration to the Sun Belt in the US.

  • Earning the ENERGY STAR means products meet strict energy efficiency guidelines set by the US Environmental Protection Agency. By choosing ENERGY STAR certified heating and cooling equipment and taking steps to optimize its performance, you can enhance the comfort of your home while saving energy. Saving energy helps you save money on utility bills and protect our climate by helping prevent harmful carbon pollution and reducing other greenhouse gases.
  • he central air conditioner also needs a blower motor – which is usually part of the furnace – to blow the cool air through the duct system. The only way to ensure that your new air conditioner performs at its rated efficiency is to replace your heating system at the same time. It’s especially recommended if your furnace is over 15 years old. If you purchase a new energy-efficient air conditioner but connect it to an older furnace and blower motor, your system will not perform to its rated efficiency.

  •  (born March 6, 1917, Newark, Del.—died March 26, 2011, Kingsport, Tenn.), American chemist who discovered the powerful adhesive Super Glue while working as a chemist for Eastman Kodak, conducting research on cyanoacrylates to be used in clear plastic gunsights during World War II. Because the sticky cyanoacrylates were difficult to handle, Coover abandoned the research. In 1951 a colleague used the substance during a test to find a heat-resistant compound for jet cockpit canopies and was dismayed when it adhered to—and badly damaged—the lab equipment. Coover, however, recognized its unique ability to bond without the need for heat or pressure

Super Glue was Invented by Accident, Twice - 0 views

super glue invented by accident

shared by Shelby Tenney on 09 Jan 14 - No Cached
  • Super Glue, also known as cyanoacrylate, was
  • originally discovered in 1942 by Dr. Harry Coover, who by the way died last month on March 26th, 2011
  • Nine years later, in 1951
  • ...8 more annotations...
  • Coover was attempting to make clear plastic gun sights to be put on guns used by Allied soldiers in WWII.  One particular formulation he came up with didn’t work well for gun sights, but worked fantastically as an extremely quick bonding adhesive.  Surprisingly, despite the commercial potential of such a product, Coover abandoned that formulation completely as it obviously wasn’t suitable for his current project, being too sticky.
  • canopies
  • for jet canopies
  • Dr. Coover was the supervisor of a project looking at developing a heat resistant acrylate polymer for jet canopies.
  • Fred Joyner was working on that project and at one point used the rediscovered Super Glue and tested it by spreading ethyl cyanoacrylate between a pair of refractometer prisms.  To his surprise, the prisms became stuck very solidly together.  This time, Coover did not abandoned the cyanoacrylate (Super Glue), rather,  he realized the great potential of a product that would quickly bond to a variety of materials and only needed a little water to activate, which generally is provided in the materials to be bonded themselves.
  • Super Glue was finally put on the market in 1958 by Eastman Kodak and was called the slightly less catchy name of “Eastman #910″, though they later re-named it “Super Glue”.
  • Note: It should be noted here that while Super Glue was originally invented by accident thanks to WWII, it was not, as a popular urban legend tells, accidentally discovered by soldiers in WWII who then subsequently began using it to seal up battle wounds.  Rather, it was discovered as described above and didn’t hit the public market until well after WWII had ended
  • Interestingly though, according to its creator, Dr. Harry Coover, Super Glue actually was used  in the Vietnam War to help close up wounds on soldiers while they were being transported to hospitals to then receive stitches.  Today, a form of cyanoacrylate is often used in place of or in conjunction with traditional sutures.

gum inventor history

shared by bailey spoonemroe on 17 Jan 14 - No Cached
  • Ingredients
  • The various latexes are taken from trees in much the same way that rubber is obtained. The tree is gashed, and the latex drips into canvas bags. It is then boiled to reduce water content, hardened, and kneaded into blocks weighing about 25 pounds (11 kilograms). After shipment to a gum factory, it is purified by heating and straining before being put into a mixer, a vat in which other ingredients are added. After cooling, the mixture is flattened by rolling machines, cut into sticks, and fed into a machine for wrapping and packaging.
  • This is the process used for the standard stick of chewing gum. Gum is also sold in candy-coated pellets or tablets, soft bubble gum, gum balls, and slabs or sticks of bubble gum. Each type is put through a different process. Some bubble gum, for instance, is extruded, or squeezed through holes while still warm, then cut or shaped before being wrapped.Gum balls are coated with a sealer and then sprayed repeatedly with sugar syrup that hardens. Next they are polished with an edible wax. Candy-coated pellets or tablets are treated in much the same way.Chewing gum is a popular product around the world. Manufacturers are located on almost every continent. However, the world’s largest manufacturer of chewing gum is the William Wrigley Jr. Company of Chicago. Other U.S. manufacturers include the Topps Company and the Ford Gum & Machine Company
