Nuclear magnetic resonance separation
First Claim
1. A chemical separation comprising:
- a radio frequency power supply capable of providing radio frequency electric current on any one of a wide range of frequencies from approximately 1 KHZ to 100 KHZ anda radio frequency power transformer capable of a broard spectrum of frequencies having a plurality of windings and connections for transferring radio frequency power at the proper impedance to electrodes in a solution and to a radio frequency coil for exciting chemical species to nuclear magnetic resonance, andmeans for producing both magnetic resonance selectively in specific species in a mixture containing a plurality of chemical species and an alternating magnetic field due to that resonance in specific species comprising a magnet having a unidirectional magnetic field in a gap between its pole pieces with a box of said mixture in solution in the gap, and a radio frequency coil capable of generating an imposed alternating magnetic field through said box and perpendicular to the unidirectional field in the box, said coil encircling the box with the mixture and being powered by said power supply with sufficient radio frequency energy on the Larmor frequency of the species to be separated as to be capable of exciting these selected species into resonant oscillation with the coil andmeans to act upon the resonating species in order to move the resonating species relative to other species in the mixture comprising electrodes capable of conducting electric current, synchronized to the frequency of the alternating magnetic field, through the mixture in a plane perpendicular to an alternating magnetic field of the resonating chemical species and of thereby exerting electromechanical, physical thrust against the resonating species to move it through the box and away from non-resonating species of the mixture.

Abstract
The mechanisms that operate in nuclear magnetic resonance spectroscopy are applied to the art of magnetohydrodynamics in order to provide a system that can separate one or more chemical species from a mixture in that these NMR principles are employed to achieve a stronger magnetomotive force acting upon some components of a mixture than on other components when all of the components of a mixture are situated in a magnetohydrodynamic condition in which physical force being applied to move the components results from an high frequency magnetic field extending through the mixture in a direction perpendicular to a synchronous high frequency alternating electric field also extending through the mixture, the stronger magnetomotive force acting selectively on some components being the result of an induced resonance in those components which enables those components to absorb energy from the high frequency alternating magnetic field and to thereby interact more energetically with the perpendicular electric field for a greater magnetomotive impulse. Those components that have received the greater magnetomotive impulse by virtue of induced nuclear magnetic resonance at the frequency at which they resonate are impelled to move through solution at a greater rate than others not resonating at that frequency and are separated by their relative positions in solution after a period of migration.
