Abstract
Abstract A magnetic device for treating hydrocarbon fuel, including a passageway having an inlet and an outlet for the passage of the hydrocarbon fuel, a pair of elongated magnets and with each magnet magnetized to have one pole extending along one longitudinal face and the other pole extending along the opposite longitudinal face, the pair of magnets located along and on opposite sides of the passageway and with the faces of the magnets having like poles spaced from and substantially parallel to each other, and the pair of magnets providing a substantially unipolar flux field on fuel flowing in the passageway.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
192 words
A magnetic device for treating hydrocarbon fuel, including a hollow elongated casing of non-magnetic material, the casing including a pair of end portions and with each end portion including a fitting for providing an inlet and outlet for the fuel, a pair of elongated magnets and with each magnet magnetized to have one pole extending along one longitudinl face and the other pole extending along the opposite longitudinal face and with each longitudinal face having a particular width, a pair of magnets located within the casing and retained in position by the inner walls of the casing and with faces of the magnets having like poles spaced from each other and substantially parallel to each other and with the distance between the spaced faces of the pair of magnets substantially smaller than the particular width of the spaced faces to form an elongated substantially rectangular cross-section passageway between the magnets for the fuel in communication with the inlet and outlet fittings and with the passageway being substantially free of any ferrous metal, and the pair of magnets providing a substantially unipolar flux field on fuel flowing in the passageway between the magnets.
Claim 2
Dependent Claim
192 words
A magnetic device for treating hydrocarbon fuel, including a hollow elongated casing of non-magnetic material, the casing including a pair of end portions and with each end portion including a fitting for providing an inlet and outlet for the fuel, a pair of elongated magnets and with each magnet magnetized to have one pole extending along one longitudinl face and the other pole extending along the opposite longitudinal face and with each longitudinal face having a particular width, a pair of magnets located within the casing and retained in position by the inner walls of the casing and with faces of the magnets having like poles spaced from each other and substantially parallel to each other and with the distance between the spaced faces of the pair of magnets substantially smaller than the particular width of the spaced faces to form an elongated substantially rectangular cross-section passageway between the magnets for the fuel in communication with the inlet and outlet fittings and with the passageway being substantially free of any ferrous metal, and the pair of magnets providing a substantially unipolar flux field on fuel flowing in the passageway between the magnets.
Claim 3
Dependent Claim
54 words
The magnetic device of claim 1 wherein the cross-section of each magnet is rectangular and having a ratio between the long side and the short side of more than two to one and wherein the long sides of the magnets are spaced from each other and with the casing having a substantially square configuration.
Claim 4
Dependent Claim
16 words
The magnetic device of claim 1 wherein the magnets are formed from a ceramic magnetic material.
Claim 5
Dependent Claim

Claim 6
Dependent Claim
150 words
A magnetic device for treating hydrocarbon fuel, including an elongated substantially rectangular cross-section passageway substantially free of ferrous metal and having an inlet and an outlet for the passage of the hydrocarbon fuel, a pair of elongated magnets and with each magnet magnetized to have one pole extending along one longitudinal face and the other pole extending along the opposite face and the other pole extending along the opposite longitudinal face and with each longitudinal face having a particular width, a pair of magnets located along and on opposite sides of the passageway and with faces of the magnets having like poles spaced from and substantially parallel to each other and with the distance between the spaced faces of the pair of magnets substantially smaller than the particular width of the spaced faces, and the pair of magnets providing a substantially unipolar flux field on fuel flowing in the passageway.
Claim 7
Dependent Claim
150 words
A magnetic device for treating hydrocarbon fuel, including an elongated substantially rectangular cross-section passageway substantially free of ferrous metal and having an inlet and an outlet for the passage of the hydrocarbon fuel, a pair of elongated magnets and with each magnet magnetized to have one pole extending along one longitudinal face and the other pole extending along the opposite face and the other pole extending along the opposite longitudinal face and with each longitudinal face having a particular width, a pair of magnets located along and on opposite sides of the passageway and with faces of the magnets having like poles spaced from and substantially parallel to each other and with the distance between the spaced faces of the pair of magnets substantially smaller than the particular width of the spaced faces, and the pair of magnets providing a substantially unipolar flux field on fuel flowing in the passageway.
Claim 8
Dependent Claim
