Vacuum engineering
Vacuum technology is a method used to evacuate air from a closed volume by creating a pressure differential from the closed volume to some vent, the ultimate vent being the open atmosphere. When using an industrial vacuum system, a vacuum pump or generator creates this pressure differential. A variety of technical inventions were created based on the idea of vacuum discovered during the 17th century. These range from vacuum generation pumps to X-ray tubes, which were later introduced to the medical field for use as sources of X-ray radiation. The vacuum environment has come to play an important role in scientific research as new discoveries are being made by looking back to the basic fundamentals of pressure. The idea of “perfect vacuum” cannot be realized, but very nearly approximated by the technological discoveries of the early 20th century. Vacuum engineering today uses a range of different material, from aluminum to zirconium and just about everything in between. There may be the popular belief that vacuum technology deals only with valves, flanges, and other vacuum components, but novel scientific discoveries are often made with the assistance of these traditional vacuum technologies, especially in the realm of high-tech. Vacuum engineering is used for compound semiconductors, power devices, memory logic, and photovoltaics.
Fantom Technologies
In 1989, British-born James Dyson (inventor of dual-cyclone vacuums) and Canada's IONA Appliances (the predecessor of Fantom Technologies) made a licensing deal in which the company would manufacture and sell a line of commercial dual-cyclonic upright vacuums called Vectron, for SC Johnson Wax, on which Dyson held the patent. Two years later, SC Johnson exited the commercial vacuum business and IONA renamed the vacuums to "Fantom". 1993 brought a successful infomercial for the original Fantom vacuum. One year later, the vacuum offered a HEPA filter as an option. In 1995, the vacuum was renamed the Fantom Thunder.In 1996, IONA Appliances became Fantom Technologies, Inc. and introduced the Fantom Fury. The vacuum was smaller than the Thunder unit and was lighter and less expensive. Again, it achieved success through a television infomercial. It was less able to clean carpets due to a weaker motor.Fantom Technologies offered a canister-style vacuum in 1998 called the Fantom Lightning. It was sold at a price of $329 through a television infomercial hosted by Jim Caldwell (and produced by his then-business Future Thunder Productions). Again, it sold well, but the vacuum had defects including a like poor handle release on the power nozzle and poor wand and hose design.A later model was the Fantom Cyclone XT, released in 1999. Sold again through an infomercial hosted by Cheryl Watson and Jim Caldwell, the vacuum was engineered similar to the Lightning, but as upright. It was successful.James Dyson ended his partnership with Fantom Technologies in early 2001. That same year, Fantom released a single-cyclone vacuum called the Fantom Crosswinds, which unlike the previous vacuums, was a failure due clogging problems.The Wildcat which is equivalent to Westinghouse Unplugged
