Some fresheners operate by releasing a quick burst of scent every minute, 10 minutes, or 30 minutes so that you don't become too accustomed to the ...
The obvious way to do this was to use an additional turbine to extract energy from the jet and use this energy to drive a low-pressure compressor or fan capable of 'breathing' far more air than the jet engine itself and forcing this additional air rearwards as a 'cold jet'. The complete system is known as a 'turbofan'." The first embodiment was ...

They typically emit fragrance to mask odors but may use other methods of action such as absorbing, bonding to, or chemically altering compounds in the air that produce smells, killing organisms that produce smells, or disrupting the sense of ...
He also invented [43] the idea of the "jet wing", in which air from the compressor of a jet engine is bled off to large "augmented" vents in the wings to provide lift for VTOL aircraft. A small amount of high-pressure air is blown into a venturi , which in turn sucks a much larger volume of air along with it, thus leading to "thrust augmentation".

The Pratt & Whitney J58 (company designation JT11D-20) is an American jet engine that powered the Lockheed A-12, and subsequently the YF-12 and the SR-71 aircraft. It was an afterburning turbojet engine with a unique compressor bleed to the afterburner that gave increased thrust at high speeds.
The Power Jets W.2 was a British turbojet engine designed by Frank Whittle and Power Jets (Research and Development) Ltd.Like the earlier Power Jets W.1, the reverse-flow combustion configuration included a double-sided centrifugal compressor, 10 combustion chambers and an axial-flow turbine with air-cooled disc.
He also invented a device to combine sound with motion pictures. [18] This attracted the attention of local entrepreneur Joseph A. Numero of Minneapolis, Minnesota .
