Chicago and Cincinnati were the first two American cities to enact laws ensuring cleaner air in 1881.

For example, a typical vacuum cleaner produces enough suction to reduce air pressure by around 20 %.

A vacuum cleaner is a device that uses an air pump to create a partial vacuum to suck up dust and dirt, usually from floors, and optionally from other surfaces as well.

Nicknamed the " Puffing Billy ", Booth's first petrol-powered, horse-drawn vacuum cleaner relied upon air drawn by a piston pump through a cloth filter.

In 2004 a British company released Airider, a hovering vacuum cleaner that floats on a cushion of air.

This had the advantage of never " flooding " the engine, as any liquid fuel droplets would fall out of the carburetor instead of into the intake manifold ; it also lent itself to use of an oil bath air cleaner, where a pool of oil below a mesh element below the carburetor is sucked up into the mesh and the air is drawn through the oil-covered mesh ; this was an effective system in a time when paper air filters did not exist.

Clean air delivery rate is the amount of clean air an air cleaner provides to a room or space.

For example, an air cleaner with a flow rate of 100 cfm ( cubic feet per minute ) and an efficiency of 50 % has a CADR of 50 cfm.

Dark Helmet takes Spaceball One to Druidia, and transforms the ship into Mega Maid, a giant robotic maid with a vacuum cleaner that begins sucking the air from the planet.

Spaceball One's secret weapon is its ability to transform, in parody of various transforming robot toys ( Barf describes it as " a Transformer "), into Mega Maid, a colossal cleaning woman holding a gigantic vacuum cleaner used to extract air from other planets and take it back to planet Spaceball.

Scallon was five when her parents chose to return to Ireland because of the London smog and the harmful effect it had on some of their children ; their doctor recommended they return to the cleaner air of Derry.

Another demonstration is to direct the air flow from, e. g., a vacuum cleaner operating in reverse, tangentially past a round cylinder.

The whole TE range had a higher centre pressing in the bonnet to accommodate the six-cylinder engine's air cleaner.

Like the TE, the whole TF range had a higher centre pressing in the bonnet to accommodate the six-cylinder engine's air cleaner.

The US $ 296, package included a V8 rated at at 4800 rpm ) with a single Carter AFB four-barrel carburetor and dual exhaust, chromed valve covers and air cleaner, 7 blade clutch fan, a floor-shifted three-speed manual transmission with Hurst shifter, stiffer springs, larger diameter front sway bar, wider wheels with 7. 50 × 14 redline tires, hood scoops, and GTO badges.

Dust being " sucked " into a vacuum cleaner is actually being pushed in by the higher pressure air on the outside of the cleaner.

Dust can be removed with a vacuum cleaner, gas duster or compressed air.

Common means to remedy clogging include use of toilet plunger, drain cleaner or a plumber's snake.

This means that the cleaner does not need to bring any additional water on the cleaning trolley.

It focused on improving transportation, not as an end in itself, but as the means to achieve important national goals including economic progress, cleaner air, energy conservation, and social equity.

Will our bombs be cleaner or will their fallout be less harmful to future generations of children??

As with the penultimate Giselle release ( Wolff's abridgment for RCA Victor ) I find the cleaner, less razor-edged monophonic version, for all its lack of big-stage spaciousness, the more aurally tolerable -- but this may be the result of processing defects in my SD copies.

His work in this period became increasingly Modernist in spirit, with far less overtly political context and a cleaner style, in keeping with contemporary work by Hans Arp and Piet Mondrian.

The second version, which featured larger images and cleaner ( albeit less fluid ) scene animation than the first version, was introduced in the beginning 1982 season and used for both the U. S. and Canadian broadcasts of You Can't Do That on Television until the end of the show in 1990.

Seeds from botanical gardens, or other cultivated sources are much cleaner and less likely to rot.

Flammability concerns led William Joseph Stoddard, a dry cleaner from Atlanta, to develop Stoddard solvent as a slightly less flammable alternative to gasoline-based solvents.

Although liquefied petroleum gas and hydrogen have cleaner combustion, they are used to fuel much less efficient petrol engines and are not as widely available.

Lamp oil burns cleaner and with less odor than kerosene.

This method results in a faster, cleaner sample with less chance of haemolysis.

Coil taps are most commonly found on single coil pickups, and involve an extra hook-up wire being included during the manufacture of the pickup so the guitarist can choose to have all the windings of the pickup included in the circuit, for a fatter, higher output sound with more midrange ; or switch the output to " Tap " into the windings at a point that is less than the full coil for a brighter, lower output, cleaner sound.

In terms of hardware, the new motherboard was a cleaner design that drew less power and resolved audio noise issues that interfered with the Ensoniq synthesizer in the original motherboard.

In addition, the gas laser was less sensitive to external vibration, a must in certain industrial environments, and generated less photon-shot noise than the solid-state laser diode, resulting in a cleaner, less " busy " on-screen image.

Typically, starch produces a shorter ( cleaner bite, less chewy ) texture than gelatin.

Distributed feed curtains or HRS curtain arrays provided a cleaner pattern, ability to steer the pattern in elevation and azimuth, much higher efficiency, and significantly higher gain in less space.

They found that kenaf newsprint made for stronger, brighter and cleaner pages than standard pine paper with less detriment to the environment.

Although offering inferior cooling capabilities, the bonnet was designed to give a cleaner line through the air with less air resistance at motorway speeds.

While many 1959 model cars featured bigger and sharper fins, Olds featured more subdued " oval " fins and far less chrome than the ' 58 model for a much cleaner look.

In modern times, because of cleaner air standards in Europe and North America, the dark-bodied moth is becoming less frequent, again demonstrating the adaptive shifts in the peppered moth population.

The fuel was cleaner than manufactured gas and less expensive to produce.

It is relatively less visited site and as a result is a quiet beach with sparkling white sand and cleaner seawater.

In 1924, Atlanta dry cleaner W. J. Stoddard worked with Lloyd E. Jackson of the Mellon Institute of Industrial Research to develop a less volatile dry cleaning solvent as an alternative to the petroleum solvents in use.
