There are many innovations that are used in everyday life, many of them are useful and often taken for granted. For instance, before vacuum cleaners were invented, to clean, people use brooms to tidy up dirt and garbage. Surprisingly, a rebellious idea was formed that influenced cleaning practices and restrained disease. The idea to invent a machine that would pull dirt and dust was created by a British inventor, Hubert Cecile Booth, known today as the vacuum cleaner.
Before the powerful vacuum cleaner, there was a manually powered machine that was operated in a very difficult way. According to the great idea finder, “The first vacuum cleaners had to be operated manually. Two persons were needed for some machines were too large, one to operate the bellows and the other to move the mouthpiece over the floor. The dust was blown into the air”. This first machine that was operated manually was created by Ives W. Mcgaffey in 1869. This device was made very difficult, society did not adore it because it was really hard for them to operate. Later on, the first powered cleaner was developed by Hubert Cecile Booth. This device was very large, it was driven by an oil engine and had to be drawn by horses because of its size.
The vacuum cleaner is a household appliance that cleans by suctioning dirt and dust. According to “how stuff works” they explained that “ Vacuum cleaners put suction to work when cleaning up the dust and wastes in your house.” The suction is created by an air pump, the vacuum creates a pressure between the inside of the machine and the outside air and dirt where
dust is taken into the lower zone of the vacuum. The rasping on the carpet causes the dust to be removed from the carpet or other surface. Vacuum cle...

...ls, etc. Some such as the Roomba are equipped with an impeller motor to create an actual vacuum. By the end of 2003 about 570,000 units were sold worldwide.” (Beals vacuum sales & service ) these developments are meant to improve on existing models and technology. Today, the vacuum cleaner has been effective in minimizing the amount of work for the domestic cleaner. It has also reduced the time and energy to clean. In other words, vacuum cleaner today has become a percieveable and essential household appliances for most domestic homes, business, and work. Today people use vacuum cleaners for many different reasons. It can be used to vacuum at home, business, work, car, or environmental purposes. In conclusion, vacuum cleaners are one of the greatest household benefits ever invented because it immensely to the world impact on Environmental and health. 760 words.
Norbert Rillieux invented the triple effect vacuum evaporator. The "triple effect" is for the multiple things that the system does all at the same time. The "vacuum" is for the vacuum of air that is used in the system, and the "evaporator" is for the sugarcane liquid syrup that is heated and evaporated into regular sugar. The actual system is somewhat complicated, so please see the picture that is provided.
On June 8, 1869, Chicago inventor Ives McGaffey patented a vacuum, this was a patent for absorb dirtiness also cleaned rugs and more, it was not a motorized vacuum cleaner. McGaffey called his machine wood and canvas contraption the Whirlwind. Today it is known as the first hand-pumped vacuum cleaner in the United States. On June 8, 1869, Chicago inventor McGaffey patented a "sweeping machine." While this was the first patent for a device that cleaned, it was not a motorized vacuum cleaner. McGaffey called his machine -- vacuum -- the Whirlwind. Today it is known as the first hand-pumped vacuum cleaner in the United States.
The first push giving headway into Dyson’s technical advances and the conception of the DC01 Vacuum lies in the malfunction of the existing vacuum’s with bags for example products by Hoover and Vac. Dyson’s household ‘top of the range’ Hoover model began to loose power soon after starting the job, this was usually a...
A vacuum cleaner is a device that uses an air pump to suck up dirt into a dust bag for later disposal. In Howard Nemerov's "The Vacuum," a widowed husband mourns the death of his wife while he observes their vacuum in his quiet house. As he studies the vacuum he notices it "sulks in the corner closet" (line 2). His observation sets the tone for the poem and personifying the household device. As he continues to personify the vacuum throughout the poem, he notes the lifelessness of the vacuum, memories of his wife using the vacuum, and how "life is cheap as dirt" (line 13) but dirt is still everywhere even when she is gone. The speaker in "The Vacuum," uses the vacuum cleaner to symbolize his wife's death, the connection to his wife, and how he perceives his life after her death.

Don't let all the acronyms intimidate you- read carefully and you'll be fine. If the nightclub/bouncer analogy doesn't work for you, you could also think of them as little vacuum pumps and blowers. An extremely detailed view of their actual mechanisms is beyond current knowledge.
The Bissell Cleanview Helix is for people seeking a full sized vacuum cleaner on a budget. Like other varieties at this price point, it is upright, bagless, and features simple controls. It comes with all the expected bells and whistles. The vacuum is sufficient for cleaning an entire home, even stairs, edges, and bare floors. This isn't a high-end machine, and it won't take a beating for years like some of the expensive options. If you need a vacuum for normal use, it gets the job done.
For my fourth technology journal I read an article from Popular Mechanics called, “The Hair Dryer That Doesn’t Get Hot” by Alexander George. In this article Alexander tries the new Dyson Supersonic hair dryer (debuted in September) with a price tag of $400. The Supersonic has a very futuristic look. It has three attachments, and is about the same length as a “normal” dryer. Instead of having the air come out of a nozzle part, there is an open circle at the top. This dryer has the motor in the handle, which is unlike other dryers whose motor is in the back. Furthermore, the air uses a vent called an airfoil. This is the same property that produces lift in airplanes to create a breeze. Inside the air vent the Supersonic has a metal impeller
John Kay, an English weaver invented the flying shuttle, a product that could cut cotton twice as fast. When other inventors saw what Kay had made, they wanted to do the same. One problem still remained. Yarn was not being fed fast enough through the weaver, but in 1769, two new inventions solved the problem. The spinning jenny and the water-powered frame, both of which fed yarn through the flying shuttle faster. Cleaning the cotton was a boring and time consuming job, so in 1793, Eli Whitney invented the cotton gin. The gin cleaned cotton up to 50 times faster than a human could.
The electrostatic precipitator (ESP) is a machine used in factories, to clean out the waste solid particle, for example ash from the exhaust gas, allowing clean exhaust gas exit through the chimney. The electrostatic precipitator functions by using first allow the exhaust gas with the waste solid particles pass through the Nozzle as shown in the diagram below. Then the exhaust gas passes through inlet gas distribution, which evenly distributes the gas as shown below in a turquoise color, and starts going through the Discharge electrodes and the collector plates, which is shown in the diagram red and blue respectively. The discharge electrodes, which are powered by high voltage direct current, ionize the gas along with the other solid waste particles negatively. The collector plates are also charged with high voltage electricity, but it is positively charged, therefore attracting the negatively charged solid particle, because oppositely charged particles attract. This allows the clean exhaust gas pass through the other end, while the solid waste particles are trapped in the collector plates. Eventually when there are enough solid waste particles collected on the collector plates, the collect plates shakes off the collected waste, where it drops to the bottom of the shaft as shown in the diagram as “Hopper”.
Willis Haviland Carrier invented the first air conditioner in 1902. This was designed to boost the working process control in a printing plant. Carrier’s invention controlled temperature and humidity. The low heat and humidity helped keep the paper dimensions and ink alignment the same. Later his invention was used to populate productivity in the workplace. The Carrier Air Conditioning Company of America developed for the increasing demands. Gradually, air conditioning was used to help increase comfort in homes and cars. Residential sales increased rapidly in the 1950's.
Compressor: Function of compressor is removing the vapour from evaporator and increase the pressure & temperature up to condensed into the diffuser.
