Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
95 words
An apparatus for sterilizing an aqueous medium comprising: means for passing an aqueous medium along a path; means along said path for producing ultraviolet rays and subjecting said aqueous medium to said ultraviolet rays; and means along said path in a region in which said aqueous medium is subject to said ultraviolet rays for subjecting said aqueous medium, while it is subjected to said ultraviolet rays, to a magnetic field, said means for subjecting said aqueous medium to said magnetic field including a plurality of magnets having poles arranged in opposite directions to one another.
Claim 2
Independent Claim
95 words
An apparatus for sterilizing an aqueous medium comprising: means for passing an aqueous medium along a path; means along said path for producing ultraviolet rays and subjecting said aqueous medium to said ultraviolet rays; and means along said path in a region in which said aqueous medium is subject to said ultraviolet rays for subjecting said aqueous medium, while it is subjected to said ultraviolet rays, to a magnetic field, said means for subjecting said aqueous medium to said magnetic field including a plurality of magnets having poles arranged in opposite directions to one another.
Claim 3
Dependent Claim
26 words
The apparatus defined in claim 1 wherein said means for subjecting said medium to said magnetic field comprises a plurality of permanent magnets along said path.
Claim 4
Dependent Claim
17 words
The apparatus defined in claim 1, further comprising means along said path for ozonizing the aqueous medium.
Claim 5
Dependent Claim
17 words
The apparatus defined in claim 1, further comprising means for controlling the temperature of the aqueous medium.
Claim 6
Dependent Claim
25 words
The apparatus defined in claim 4 wherein the means for subjecting said aqueous medium to said magnetic field comprises a plurality of annular permanent magnets.
Claim 7
Dependent Claim
24 words
The apparatus defined in claim 1 wherein said means for passing said aqueous medium along said path includes a pump displacing said aqueous medium.
Claim 8
Dependent Claim
16 words
The apparatus defined in claim 6, further comprising an ozonizing device for ozonizing said aqueous medium.
Claim 9
Dependent Claim
12 words
The apparatus defined in claim 6 wherein said pump is manually operable.
Claim 10
Dependent Claim
30 words
The apparatus defined in claim 1, further comprising a source of electric power independent of line current connected to said means for subjecting said aqueous means to said ultraviolet rays.
Claim 11
Dependent Claim
39 words
The apparatus defined in claim 1 wherein said means for subjecting said aqueous means to ultraviolet rays includes a quartz glass ultraviolet-ray-generating tube surrounded by said plurality of permanent magnets including at least one permanent magnet disposed coaxially therewith.
Claim 12
Dependent Claim
36 words
The apparatus defined in claim 10 wherein said path is defined by a guide means surrounding the quartz glass tube coaxially and guiding said aqueous medium over substantially the entire length of said quartz glass tube.
Claim 13
Dependent Claim
38 words
The apparatus defined in claim 11 wherein a filter element surrounds but is spaced from said guide means, the inlet for said aqueous medium opening into a space within the housing of said apparatus and said filter element.
Claim 14
Dependent Claim
19 words
The apparatus defined in claim 11 wherein said permanent magnets have an axial length of at least 3 mm.
Claim 15
Dependent Claim
47 words
The apparatus defined in claim 1 wherein said means for subjecting said aqueous medium to said magnetic field is an annular array of said permanent magnets and guide means for passing said aqueous medium along at least one of the peripheries of said array of permanent magnets.
Claim 16
Dependent Claim
19 words
The apparatus defined in claim 14 wherein said guide means also surrounds said annular array of permanent magnets coaxially.
Claim 17
Dependent Claim
33 words
The apparatus defined in claim 1 wherein the means for passing said aqueous medium along said path includes a substantially tubular guide composed of quartz-glass or a synthetic material pervious to ultraviolet rays.
