Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
145 words
A magnetic fluid conditioner for acting on a fluid being transmitted through a conduit, said fluid conditioner comprising: (a) a housing having an open top side and a closed bottom side and closed ends, the closed ends each having an aperture therethrough in co-axial alignment; (b) an elongated conduit passing through the apertures in the ends of said housing and extending from both ends thereof; (c) at least two permanent bar magnets in said housing positioned in opposition at the periphery of said conduit, and with a pole on each magnet positioned along said conduit being directly adjacent to the periphery of said conduit; and, (d) a plurality of magnetic metallic pole pieces bridging the magnets on opposing sides of said conduit to provide a metallic flux path between said magnets; said conduit, magnets, and pole pieces being retained in fixed relationship within said housing.
Claim 2
Dependent Claim
145 words
A magnetic fluid conditioner for acting on a fluid being transmitted through a conduit, said fluid conditioner comprising: (a) a housing having an open top side and a closed bottom side and closed ends, the closed ends each having an aperture therethrough in co-axial alignment; (b) an elongated conduit passing through the apertures in the ends of said housing and extending from both ends thereof; (c) at least two permanent bar magnets in said housing positioned in opposition at the periphery of said conduit, and with a pole on each magnet positioned along said conduit being directly adjacent to the periphery of said conduit; and, (d) a plurality of magnetic metallic pole pieces bridging the magnets on opposing sides of said conduit to provide a metallic flux path between said magnets; said conduit, magnets, and pole pieces being retained in fixed relationship within said housing.
Claim 3
Dependent Claim
16 words
A magnetic fluid conditioner in accordance with claim 1 in which said conduit is a pipe.
Claim 4
Dependent Claim
17 words
A magnetic fluid conditioner in accordance with claim 1 in which said conduit is a metal tube.
Claim 5
Dependent Claim
24 words
A magnetic fluid conditioner in accordance with claim 1 in which said magnets are elongated bar magnets positioned to be parallel with said conduit.
Claim 6
Dependent Claim
158 words
A magnetic fluid conditioner for acting on a fluid being transmitted through a conduit, said fluid conditioner comprising: (a) a housing having an open top side and a closed bottom side and closed ends, the closed ends each having an aperture therethrough in co-axial alignment; (b) an elongated sleeve supported by the apertures in the ends of said housing, the inside diameter of said sleeve being such as will receive said fluid transmitting conduit passing through said sleeve; (c) at least two permanent bar magnets in said housing positioned in opposition at the periphery of said sleeve, and with a pole on each magnet positioned along said sleeve being directly adjacent to the periphery of said sleeve; and, (d) a plurality of magnetic metallic pole pieces bridging the magnets on opposing sides of said sleeve to provide a metallic flux path between said magnets; said sleeve, magnets, and pole pieces being retained in fixed relationship within said housing.
Claim 7
Dependent Claim
158 words
A magnetic fluid conditioner for acting on a fluid being transmitted through a conduit, said fluid conditioner comprising: (a) a housing having an open top side and a closed bottom side and closed ends, the closed ends each having an aperture therethrough in co-axial alignment; (b) an elongated sleeve supported by the apertures in the ends of said housing, the inside diameter of said sleeve being such as will receive said fluid transmitting conduit passing through said sleeve; (c) at least two permanent bar magnets in said housing positioned in opposition at the periphery of said sleeve, and with a pole on each magnet positioned along said sleeve being directly adjacent to the periphery of said sleeve; and, (d) a plurality of magnetic metallic pole pieces bridging the magnets on opposing sides of said sleeve to provide a metallic flux path between said magnets; said sleeve, magnets, and pole pieces being retained in fixed relationship within said housing.
Claim 8
Dependent Claim
24 words

Claim 9
Dependent Claim
230 words
A magnetic fluid conditioner for acting on a fluid being transmitted through a conduit, said fluid conditioner having magnetic units used in pairs, each pair comprising: (a) a first magnetic unit having a housing with an open side and a closed side opposite thereto, at least one permanent magnet retained within said housing, and a U-shaped magnetic metallic clamp positioned at the open side of said housing and with the opposing side elements of said clamp extending in the direction of the closed side of said housing; and, (b) a second magnetic unit having a housing with an open side and a closed side opposite thereto, at least one permanent magnet retained within said housing, and a U-shaped magnetic metallic clamp positioned at the open side of said housing and with the opposing side elements of said clamp extending in the direction of the closed side of said housing, the opposing side elements of the clamp on said magnetic unit making engagement with the opposing side elements of the clamp on said first magnetic unit when the two magnetic units constituting said magnetic fluid conditioner are installed on said fluid transmitting conduit with the closed side of said housings adjacent to said fluid transmitting conduit, the side elements of the two U-shaped clamps forming a continuous metallic flux path between the magnets in said first and said second magnetic units.
Claim 10
Dependent Claim
230 words
A magnetic fluid conditioner for acting on a fluid being transmitted through a conduit, said fluid conditioner having magnetic units used in pairs, each pair comprising: (a) a first magnetic unit having a housing with an open side and a closed side opposite thereto, at least one permanent magnet retained within said housing, and a U-shaped magnetic metallic clamp positioned at the open side of said housing and with the opposing side elements of said clamp extending in the direction of the closed side of said housing; and, (b) a second magnetic unit having a housing with an open side and a closed side opposite thereto, at least one permanent magnet retained within said housing, and a U-shaped magnetic metallic clamp positioned at the open side of said housing and with the opposing side elements of said clamp extending in the direction of the closed side of said housing, the opposing side elements of the clamp on said magnetic unit making engagement with the opposing side elements of the clamp on said first magnetic unit when the two magnetic units constituting said magnetic fluid conditioner are installed on said fluid transmitting conduit with the closed side of said housings adjacent to said fluid transmitting conduit, the side elements of the two U-shaped clamps forming a continuous metallic flux path between the magnets in said first and said second magnetic units.
