Abstract
Abstract A structure for subjecting liquids having a dissolved and suspended calcareous content to magnetic lines of force. The liquid is caused to pass around a number of permanent magnets developing lines of force through which the liquid moves in a path intersecting such lines of force. This is achieved by mounting the magnets in a non-ferrous carrier with the poles thereof in opposed relationship, i.e., north to north, and south to south. The liquid is confined in such a manner so that it has a number of substantially helical concentric flow paths enabling the lines of force to be cut at right angles thereto.

Claim 1
Independent Claim
141 words
Apparatus for the treatment of calcareous water with magnetic lines of force, comprising; a. a generally cylindrical outer jacket; b. walls closing the ends of said outer jacket to define a treating chamber; c. a supply opening to and a discharge opening from said treating chamber; d. a plurality of concentrically arranged passages within said treating chamber for movement of calcareous water; e. a plurality of concentrically arranged permanent magnets mounted between said concentrically arranged passages; f. said magnets being arranged in a line with like poles of contiguous magnets adjacent each other to create lines of force extending laterally of said magnets; g. a plurality of concentric sleeves defining said concentrically arranged passages; h. means for maintaining said concentric sleeves in proper spaced relationship including helical members for directing the path of movement of said calcareous water in said passages.
