Abstract
Abstract This invention provides an improved apparatus for the treatment of water to reduce the formation of scale in those mechanical devices that employ water and to enhance the service ability of liquids in other applications through the use of magnetic circuitry which maximizes the effectiveness of the magnetic flux upon fluids. The circuitry includes flat-ring true permanent magnets, collector disks with tapered transmission points, set air gaps and threaded concentrator cores. This invention makes it possible to tailor magnet spacing to meet a wide range of velocity and flow rate requirements through the use of flux separators of varying sizes and the interchangeability of the inner core.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
219 words
A magnetic fluid treatment device to maximize the reduction of mineral deposits within a fluid pipe at a particular fluid velocity, comprising: a non-magnetic cylindrical fluid conduction tube within which the fluid to be treated flows; an external inlet and outlet attachment means to support and connect said fluid conduction tube to an external fluid supply source; an elongated hollow non-magnetic concentrator core tube positioned within said fluid conduction tube and spaced therefrom to form an annular chamber therebetween for axial fluid passage; a ferrous soft magnetic concentrator core tightly contained within said concentrator core tube and extending throughout its axial length; a plurality of spaced apart magnetic members of alternating polarity, each consisting of a flat ring magnet positioned between a pair of side magnetic collector disks, whereby magnetic flux lines are communicated axially between the faces of said magnet and said disks and radially between said disks and said concentrator core; a ferrous soft magnetic concentrator can closely spaced coaxially around said magnetic members whereby magnetic flux lines are communicated axially between the faces of said magnet and said disks and radially between said disks and said concentrator can; and a plurality of adjustably sized non-magnetic flux separators whereby the spacing between said magnetic members may be tailored to increase treatment efficiency at a specified flow rate.
Claim 2
Dependent Claim
219 words
A magnetic fluid treatment device to maximize the reduction of mineral deposits within a fluid pipe at a particular fluid velocity, comprising: a non-magnetic cylindrical fluid conduction tube within which the fluid to be treated flows; an external inlet and outlet attachment means to support and connect said fluid conduction tube to an external fluid supply source; an elongated hollow non-magnetic concentrator core tube positioned within said fluid conduction tube and spaced therefrom to form an annular chamber therebetween for axial fluid passage; a ferrous soft magnetic concentrator core tightly contained within said concentrator core tube and extending throughout its axial length; a plurality of spaced apart magnetic members of alternating polarity, each consisting of a flat ring magnet positioned between a pair of side magnetic collector disks, whereby magnetic flux lines are communicated axially between the faces of said magnet and said disks and radially between said disks and said concentrator core; a ferrous soft magnetic concentrator can closely spaced coaxially around said magnetic members whereby magnetic flux lines are communicated axially between the faces of said magnet and said disks and radially between said disks and said concentrator can; and a plurality of adjustably sized non-magnetic flux separators whereby the spacing between said magnetic members may be tailored to increase treatment efficiency at a specified flow rate.
Claim 3
Dependent Claim
47 words
A magnetic fluid treatment device as recited in claim 1, further comprising: a nonferrous cylindrical protective sleeve positioned axially around said spaced apart magnetic members and having removable and caps attached thereto in sealed connection with said fluid conduction tube ends outboard of all said magnetic members.
Claim 4
Dependent Claim
19 words
A magnetic fluid treatment device as recited in claim 2 wherein said flat ring magnets are permanent ferrite magnets.
Claim 5
Dependent Claim
32 words
A magnetic fluid treatment device as recited in claim 3 wherein said concentrator core is externally threaded to increase flux density normal to the fluid flow by limiting the axial flux dimension.
Claim 6
Dependent Claim
28 words
A magnetic fluid treatment device as recited in claim 4 wherein said concentrator can is internally threaded to increase flux density between said can and said collector disks.
Claim 7
Dependent Claim
39 words
A magnetic fluid treatment device as recited in claim 5 wherein said collector disk outer and inner edges are sharpened adjacent to said concentrator can and said concentrator core threads to further increase flux density between said magnetic elements.
