Abstract
Abstract A water treatment apparatus includes a section of pipe arranged at the center of an electromagnetic force field created by a solenoid coil or the like positioned about the periphery of the pipe. A metal stationary rod is supported within the pipe and electrically insulated from the pipe such that water directed through the pipe passes by the rod. The rod is supported at both ends by insulated bearings secured within the pipe.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
139 words
A water treatment apparatus comprising, elongated pipe means having an inlet and an outlet opening at the opposite ends thereof for the passage of water therethrough, means for establishing an alternating electro-magnetic force field within said pipe means, said means for establishing the electro-magnetic force field comprising an electrical coil, a thermostat connected to said coil, with said thermostat being connected to a source of alternating current, rod means comprised of ferromagnetic material supported within said pipe means whereby water passing through said pipe means surrounds said rod means, insulating means for magnetically insulating said means for establishing an alternating electro-magnetic force field from said pipe means, and insulating means for magnetically insulating said rod from said pipe, said inlet and outlet being completely separated so that water passing through said pipe means will not re-enter said pipe means.
Claim 2
Dependent Claim
139 words
A water treatment apparatus comprising, elongated pipe means having an inlet and an outlet opening at the opposite ends thereof for the passage of water therethrough, means for establishing an alternating electro-magnetic force field within said pipe means, said means for establishing the electro-magnetic force field comprising an electrical coil, a thermostat connected to said coil, with said thermostat being connected to a source of alternating current, rod means comprised of ferromagnetic material supported within said pipe means whereby water passing through said pipe means surrounds said rod means, insulating means for magnetically insulating said means for establishing an alternating electro-magnetic force field from said pipe means, and insulating means for magnetically insulating said rod from said pipe, said inlet and outlet being completely separated so that water passing through said pipe means will not re-enter said pipe means.
Claim 3
Dependent Claim
11 words
The device of claim 1 wherein said rod means is nickel.
Claim 4
Dependent Claim
38 words
The device of claim 1 wherein said thermostat has means for closing the supply of current to said coil at approximately 96° F. and means for opening the supply of current to said coil at approximately 130° F.
Claim 5
Independent Claim
100 words
The method of treating liquids, comprising passing fluid to be treated in one direction into, through and out of a pipe means, creating an alternating electro-magnetic force field within said pipe by utilizing a source of alternating current, passing said fluid through said pipe and within said electro-magnetic force field around ferromagnetic rod means, insulating said source of alternating current from said pipe means, insulating said rod means from said pipe means, and conveying all of said water leaving said pipe means away from said pipe means so that water leaving said pipe means will not re-enter said pipe means.
Claim 6
Independent Claim
100 words
The method of treating liquids, comprising passing fluid to be treated in one direction into, through and out of a pipe means, creating an alternating electro-magnetic force field within said pipe by utilizing a source of alternating current, passing said fluid through said pipe and within said electro-magnetic force field around ferromagnetic rod means, insulating said source of alternating current from said pipe means, insulating said rod means from said pipe means, and conveying all of said water leaving said pipe means away from said pipe means so that water leaving said pipe means will not re-enter said pipe means.
Claim 7
Dependent Claim
10 words
The device of claim 4 wherein rod means is nickel.
