Abstract
Abstract This invention is directed to an adjustable-flow water conditioning device. More particularly, this invention is directed to a magnetic water conditioning device which can be manually adjusted to coordinate the conditioning effects of the device with the rate of water flow through the device. The invention is directed to a magnetic water conditioner comprising externally mounted means for permitting the distance and intensity of the magnetic field created within the conditioner by permanent magnets to be adjusted, without any disassembly of the device.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
109 words
A magnetic water conditioning device comprising: (a) a hollow housing suitable for the passage therethrough of water; (b) a hollow cup affixed to housing (a); (c) a permanent magnet enclosed around its circumference within a water-protective sleeve, and at its ends respectively by an adjusting cap and a magnet extension, said components fitting as an assembled group within the interior of internal cup (b); and (d) internal cup (b) having therein one or more ports through which water may pass, and embodying therein externally adjustable interface surfaces which can be adjusted in distance from one another to thereby regulate the rate of flow of water through the interface area.
Claim 2
Dependent Claim
109 words
A magnetic water conditioning device comprising: (a) a hollow housing suitable for the passage therethrough of water; (b) a hollow cup affixed to housing (a); (c) a permanent magnet enclosed around its circumference within a water-protective sleeve, and at its ends respectively by an adjusting cap and a magnet extension, said components fitting as an assembled group within the interior of internal cup (b); and (d) internal cup (b) having therein one or more ports through which water may pass, and embodying therein externally adjustable interface surfaces which can be adjusted in distance from one another to thereby regulate the rate of flow of water through the interface area.
Claim 3
Dependent Claim
17 words
A magnetic water conditioner according to claim 1 wherein a water filter is included on the device.
Claim 4
Dependent Claim
33 words
A magnetic water conditioning device according to claim 1 wherein the magnetic field created by the permanent magnet passes across the adjustable interface surfaces, thereby magnetically treating any water flowing between the surfaces.
Claim 5
Dependent Claim
43 words
A magnetic water conditioning device according to claim 3 including stop means for restricting the movement of said adjustable interface surfaces within a confined distance to thereby prevent the magnetic circuit created by said magnet from being broken and consequently weakening said magnet.
Claim 6
Dependent Claim
15 words
A magnetic water conditioning device according to claim 1 wherein the interface surfaces are beveled.
Claim 7
Dependent Claim
30 words
A magnetic water conditioning device according to claim 1 wherein the intensity of said magnetic field passing across said interface surfaces is in the range of 6,000 to 12,000 gauss.
Claim 8
Dependent Claim
20 words
A magnetic water conditioning device according to claim 1 wherein said magnet extension is made of a corrosion resistant substance.
Claim 9
Dependent Claim
35 words
A magnetic water conditioner according to claim 1, wherein said externally adjustable interface surfaces forming a passage that narrows quickly and then opens gradually creating a venturi effect, thereby reducing plating in the flow path.
Claim 10
Dependent Claim
33 words
A magnetic water conditioner as described in claim 4, wherein said hollow cup and said adjusting cap are threaded such that when the adjusting cap is rotated the adjustable interface surfaces are adjusted.
Claim 11
Dependent Claim
33 words
A magnetic water conditionig device according to claim 9, wherein said stop means include: a handle attached to said adjusting cap, and a stop to limit the amount of rotation of said handle.
