Patent ID: 7767082

Claim:
An apparatus, comprising: a material passageway configured for having a material flow therethrough; and at least one magnet holder disposed within the material passageway, wherein said at least one magnet holder includes a pair of spaced-apart magnet receiving spaces and a magnet holder passageway positioned between said pair of magnet receiving spaces and wherein said at least one magnet holder is disposed within the material passageway in a manner whereby all of said material is forced to flow through the magnet holder passageway of said at least one magnet holder at at least one region along the material passageway; and at least one pair of magnets, wherein a first one of said magnets is disposed within a first one of said magnet receiving spaces in a manner allowing the first one of said magnets to move therein and a second one of said magnets is disposed within a second one of said magnet receiving spaces in a manner allowing the second one of said magnets to move therein such that material in the material passageway passes through a magnetic field effect produced by said at least one pair of magnets as said material flows through the magnet holder passageway of said at least one magnet holder and wherein each magnet of said at least one pair of magnets is allowed to move independent of each other such that the magnetic field effect at least partially influences relative placement of each magnet of said at least one pair magnets.
