Abstract
Abstract Water purifying apparatus comprises outer chamber (1) and inner chamber (4) located coaxially within outer chamber (1). Inner chamber (4) contains ultra violet light generator tube (13). Water enters inlet pipe (11) flowing several times over ultra violet light generator tube (13) by means of fins (8) which form channels (9), (9A), (10) and (10A) communicating with each other through space (6) at the bottom of chamber (1) and then through outlet (12). The water may be purified further by passing through a magnetic field formed by magnets (16) and (17) formed on either side of outlet (12).

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
132 words
Apparatus for purifying water, comprising an outer chamber, an inner chamber located within the outer chamber and having at least a substantial portion of the walls thereof formed from a substantially transparent material, an ultra-violet light generating tube located within the inner chamber and means to direct the flow of water through said outer chamber and over said inner chamber, said means to direct the flow of water including a plurality of longitudinal fins extending between said inner and outer chambers, said fins comprising substantially equispaced longitudinal baffles dividing the annulus between the inner and outer chambers into wedge shaped segments with the ultra-violet light generating tube disposed at the apex of each segment and wherein water flow is directed alternately up and down adjacent segments from the inlet to the outlet.
Claim 2
Dependent Claim
132 words
Apparatus for purifying water, comprising an outer chamber, an inner chamber located within the outer chamber and having at least a substantial portion of the walls thereof formed from a substantially transparent material, an ultra-violet light generating tube located within the inner chamber and means to direct the flow of water through said outer chamber and over said inner chamber, said means to direct the flow of water including a plurality of longitudinal fins extending between said inner and outer chambers, said fins comprising substantially equispaced longitudinal baffles dividing the annulus between the inner and outer chambers into wedge shaped segments with the ultra-violet light generating tube disposed at the apex of each segment and wherein water flow is directed alternately up and down adjacent segments from the inlet to the outlet.
Claim 3
Dependent Claim
17 words
Apparatus as claimed in claim 1 wherein said inner chamber comprises the outer casing of said tube.
Claim 4
Dependent Claim
37 words
Apparatus as claimed in either claim 1 or claim 2 wherein said outer chamber comprises a cylinder and said inner chamber comprises a further cylinder smaller in diameter than said outer chamber and located substantially coaxially therein.
Claim 5
Dependent Claim
66 words
Apparatus as claimed in claim 1 wherein said outer chamber is provided with an inlet and an outlet both adjacent one end thereof and wherein said fins or baffles are arranged to direct the flow of water from said inlet to the opposite end of said outer chamber and back to said one end at least once before directing the flow of water to said outlet.
Claim 6
Dependent Claim
25 words
Apparatus as claimed in claim 1 wherein said outer chamber is provided with removable end caps which also form mounting means for said inner chamber.
Claim 7
Dependent Claim
32 words
Apparatus as claimed in claim 1 including magnetic field generating means arranged to generate a magnetic field, and means to direct the flow of water in said apparatus through said magnetic field.
Claim 8
Dependent Claim
20 words
Apparatus as claimed in claim 6 wherein said magnetic field generating means comprise at least one pair of permanent magnets.
Claim 9
Dependent Claim
50 words
Apparatus as claimed in claim 6 wherein said magnetic field generating means comprise two pairs of permanent magnets, each pair being located on either side of a water conducting conduit, one of said pairs of magnets being arranged to attract one another and the other pair to repel one another.
