Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
65 words
An apparatus for treating water comprising: a pair of halved cases diametrically positioned about an outer surface of a pipe; N-polar permanent magnets disposed in one of said cases having N-poles inwardly facing the pipe; S-polar permanent magnets disposed in the other of said cases having S-poles inwardly facing the pipe; and ceramics for far infrared radiation disposed in at least one of said cases.
Claim 2
Independent Claim
65 words
An apparatus for treating water comprising: a pair of halved cases diametrically positioned about an outer surface of a pipe; N-polar permanent magnets disposed in one of said cases having N-poles inwardly facing the pipe; S-polar permanent magnets disposed in the other of said cases having S-poles inwardly facing the pipe; and ceramics for far infrared radiation disposed in at least one of said cases.
Claim 3
Dependent Claim
31 words
An apparatus according to claim 1, wherein the N-polar and S-polar permanent magnets face each other to form magnetic lines of flux that extend at right angles relative to said pipe.
Claim 4
Independent Claim
15 words
An apparatus according to claims 1 or 2, wherein the permanent magnet is neodymium magnet.
Claim 5
Independent Claim
15 words
An apparatus according to claims 1 or 2, wherein the permanent magnet is ferrite magnet.
Claim 6
Independent Claim
35 words
An apparatus according to claims 1 or 2, wherein the permanent magnets are disposed adjacent an inlet side of the pipe and the ceramics for far infrared radiation are disposed adjacent an outlet side thereof.
Claim 7
Independent Claim
27 words
An apparatus according to claims 1 or 2 further comprising an iron backplate disposed within each said halved case adjacent outwardly facing poles of the permanent magnets.
