Magnetic structure for treating liquids containing calcareous matter

Claim 1

Apparatus for the treatment of calcareous water with magnetic lines of force comprising: a. an essentially cylindrical outer jacket formed of magnetically permeable material; b. walls closing the ends of said outer jacket to define a treating chamber; c. a supply tube of non-magnetic material for calcareous water, said supply tube having an inlet opening therein to said outer jacket and an exit opening therefrom; d. said supply tube being supported in said walls and having entrant and discharge portions extending outward from said walls; e. a plurality of permanent magnets mounted in said supply tube between said inlet opening and said exit opening; f. said magnets being arranged in line with like poles of contiguous magnets adjacent each other to create lines of force extending laterally of said supply tube; g. means extending between said supply tube and said cylindrical outer jacket for directing water entering said chamber in directions to cut said lines of force as the water moves to said exit opening comprising: i. means disposed between said supply tube and said cylindrical outer jacket for constraining said water for movement in an helical path between said supply tube and said cylindrical outer jacket; ii. said last named means being in the form of a helix made of non-magnetic material unaffecting the distribution of the lines of force provided by said permanent magnet; iii. whereby the movement of said water provides maximum cutting of said lines of force and minimum movement of said water in directions parallel to said lines of force.
