Abstract: A method and apparatus for removal of unwanted calcium from living organisms, particularly man, the invention provides non-invasive treatment modes for conditions such as arthritis and the like by subjection of the affected portion of the body to rotating magnetic fields. In particularly, magnetic members supported on a rotary plate and positioned thereon in an alternating polarity arrangement are caused to rotate at a desired angular velocity, the portion of the body which is subjected to the magnetic field being spaced from the rotating magnetic members at a desired distance. A magnetic field intensity of 50 gauss, such as at a distance of 12 inches, has been found to be effective at a rotational speed of 55 rpm, treatments preferably occurring periodically for a duration of from several minutes to approximately an hour at spaced temporal intervals over a several month period. The present treatment modes yield relief from discomfort and cause the body to eliminate excess calcium.

Abstract: A coaxial hydromagnetic device for inhibiting or reducing the adhesion of calcium and magnesium scale to heat transfer surfaces, boiler walls, and similar surfaces which must be kept free from undesirable scale deposits on exposure to "hard" water, the present hydromagnetic device comprises magnets mounted preferably within a non-ferrous receptacle, the magnets being preferably separated by plastic spacers. The respective adjacent poles of the magnets are of like polarity. The magnet-containing receptacle is supported within a water feed-line, an outer tubular envelope formed of non-ferrous material preferably containing the magnet-containing receptacle and being disposed in the water feed-line. In a particular embodiment of the invention, the outer envelope has a number of spaced annular constrictions formed therein, one or more permanent magnets being held within the central hollow cavity of the envelope preferably within a non-ferrous receptacle as aforesaid.
