Latest Patents
Curtis's latest patent, "Fine Powder Classification by Ferrofluid Density Separation," outlines a sophisticated method for separating small diameter non-magnetic particles of different densities. This method utilizes a low magnetic saturation ferrofluid combined with a high magnetic gradient, enabling the levitation of particles by overcoming magnetic attraction forces. The patent details how a density gradient column is formed within the ferrofluid, allowing each particle to reach its level of apparent density.
Another significant patent, "Classification by Ferrofluid Density Separation," explains a similar concept where non-magnetic particles are separated based on their densities through levitation processes. This method ensures sharp separation by compensating for magnetic interactions, thereby removing particles that do not meet specific size criteria for desired precision. The use of perfluorinated carriers and surfactants is preferred to support the operation of this innovative separation technique.
