the dc16, launched in 2006, is dyson's first handheld vacuum cleaner based on the same technology as used in the dc14 and dc15 root cyclone upright vacuum cleaners. the dc16 has 36 airwatts of constant suction. the dc16 shares the same styling as the other recent upright and cylinder vacuum cleaners in the dyson range, and weighs 1.5 kg 3.3 lb .
commercial devices called ‘magnetic filters’ are sold, but the name reflects their use, not their mode of operation. methods. there are many different methods of filtration; all aim to attain the separation of substances. separation is achieved by some form of interaction between the substance or objects to be removed and the filter.
magnetic tape data storage is a system for storing digital information on magnetic tape using digital recording.modern magnetic tape is most commonly packaged in cartridges and cassettes.the device that performs writing or reading of data is a tape drive. autoloaders and tape libraries automate cartridge handling. for example, a common cassette-based format is linear tape-open, which comes in .
the drum is the centerpiece of the separator, in which the separation process takes place. there are two types of drums: the chamber drum known as chamber separators and the disc drum known as disc separators . the power transmission on the spindle and thereby on the drum can take place by using one of the three drive motors: helical gears, a belt drive or direct drive, via a special motor.
an eddy current brake consists of a conductive piece of metal, either a strht bar or a disk, which moves through the magnetic field of a magnet, either a permanent magnet or an electromagnet.when it moves past the stationary magnet, the magnet exerts a drag force on the metal which opposes its motion, due to circular electric currents called eddy currents induced in the metal by the .
shure introduced beta series microphones in 1989. these feature a supercardioid designs based on sm series microphones, but with neodymium magnet structures for higher output. the series also included two new microphones specifically for drums, the beta 56 drum microphone and the beta 52 kick drum microphone, later updated to the beta 52a.
wind turbine design is the process of defining the form and specifications of a wind turbine to extract energy from the wind. a wind turbine installation consists of the necessary systems needed to capture the wind's energy, point the turbine into the wind, convert mechanical rotation into electrical power, and other systems to start, stop, and control the turbine.

in the 1950s, axel wenner-gren also got involved in the early computer business. for a railroad project connecting california with alaska, he got in touch with glenn hagen, previously an engineer with northrop aircraft, who had founded logistics research in redondo beach outside los angeles, developing computers based on magnetic drum memory.in november 1952, wenner-gren helped the company to .
ferroelectric ram feram, f-ram or fram is a random-access memory similar in construction to dram but using a ferroelectric layer instead of a dielectric layer to achieve non-volatility. feram is one of a growing number of alternative non-volatile random-access memory technologies that offer the same functionality as flash memory .
the dyson v6 range is the replacement for the dc59 handstick and dc58 handheld cordless vacuum cleaners. powered by the dyson digital motor v6. this power-dense motor uses digital pulse technology and a neodymium magnet to spin at up to 110,000 rotations per minute.
eddy currents are loops of electrical current induced within conductors by a changing magnetic field in the conductor according to faraday's law of induction. eddy currents flow in closed loops within conductors, in planes perpendicular to the magnetic field. they can be induced within nearby stationary conductors by a time-varying magnetic field created by an ac electromagnet or transformer, for example, or by relative motion between a magnet and a nearby conductor. the magnitude of the current
buckminsterfullerene is a type of fullerene with the formula c 60.it has a cage-like fused-ring structure truncated icosahedron that resembles a soccer ball, made of twenty hexagons and twelve pentagons, with a carbon atom which has one π bond and two single bonds at each vertex of each polygon and a bond along each polygon edge.
the toner image is transferred from the drum to the paper by a combination of pressure and electrostatic attraction. on many color and high-speed machines, it is common to replace the transfer corona with one or more charged bias transfer rollers, which apply greater pressure and produce a higher quality image. step 5. separation or detack
