Jacob Bogatin: Referring now in greater detail to the figures of the drawings wherein like reference characters refer to like parts, a magnetic fluid treatment device of the present invention is shown generally at 10 in FIG. 1. In the first embodiment shown in FIG. 1, the treatment device comprises a housing 100 surrounding a magnet assembly 200 through and around which the fluid being treated passes. A support structure 300 positions and holds the magnet assembly 200 within the housing. Further provided at the inlet 102 into the housing 100 is a coupling device 400 for joining the treatment device to a fluid source.

As shown in FIG. 1, the housing 100 comprises an inlet housing member 104 and an outlet housing member 106. Both of the housing members are preferably molded plastic and sealingly joined together at a seam 105 by any suitable means, for example by heat or adhesive sealing. The inlet housing member 104 has the reduced diameter inlet portion 102, and the outlet housing member 106 has a reduced diameter outlet portion 110. The two housing members 104, 106 in the preferred embodiment have a circular cross-section and are coaxially aligned when the two members are joined. The housing members are preferably made of high-strength, non-magnetic material, such as plastic, which is capable of withstanding the pressure of fluid flow therethrough. Likewise, the inlet 102 and the outlet 110 in the preferred embodiment have circular cross-sections and are coaxially aligned when the two housings members are joined. The magnet assembly 200 in the first embodiment includes, as shown in FIG. 1, three circular, planar, permanent magnets 202, 204, 206. The magnets are each magnetically oriented with the magnetic poles on the planar surfaces thereof.

Jacob Bogatin:

As shown in FIG. 1, the first magnet 202 has its negative (north) pole surface adjacent and spaced from the positive (south) pole surface of the second magnet 204. The positive (south) pole surface of the third magnet 206 is adjacent and spaced from the negative (north) pole surface of the second magnet 204 opposite the first magnet 202. All of the magnets 202, 204, 206 are cylindrical disc-shaped magnets, and each has a circular opening 210, 212, 214, respectively, therethrough.
