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.
Jim Kirby
He invented his first vacuum cleaner, called the Domestic Cyclone, in 1906, which was a hand-powered canister cleaner that used a water filtration system. His first portable vacuum cleaner for home use was manufactured and distributed by Franz Premier Electric which was founded to produce Kirby’s vacuum in 1912. Premier was later acquired by General Electric which continued to utilize Kirby’s innovations. In 1915 Kirby invented the washing machine spin cycle. The LaunDRYette Company was founded to manufacture this invention. The LaunDRYette washing machines became very popular and Kirby’s share of the profits allowed him to buy and expand his farm in Richfield. On the Richfield farm, Kirby could implement his experiments in civil engineering such as the patented lake and the mill wheel which was supported on ball bearings and could produce electricity much more efficiently than a traditional, heavy gristmill wheel.
