| 147 | Electric-field induced phase separation in liquid mixtures | US12304306 | 2007-06-18 | US08357280B2 | 2013-01-22 | Yoav Tsori |
| The invention is a method of phase separation in liquid mixtures comprising two or more components. The method comprises the steps of inserting the liquid mixture between suitably shaped and positioned electrodes and applying a voltage to the electrodes in order to produce a non-uniform electric field between the electrodes. The phase separation takes place with essentially all electrode geometries and the phase separation is reversible. The method is characterized in that the liquid mixture must contain dissociated positive or negative ions. In this case the phase separation takes place when the applied voltage is a few volts or less and when the temperature is many degrees above the binodal (coexistence) temperature Tc. The invention has many practical applications including: electrical field controlled lubrication, influencing the kinetics and spatial dependence of chemical reactions in liquid environments, controlling the propagation of light, and controlling the opacity of a window. | ||||||

| 156 | Control for an electrostatic treater | US443076 | 1982-08-09 | US4479164A | 1984-10-23 | Leon S. Siegel |
| An automatic voltage control system controls the voltage delivered to the primary winding (12) of a step-up transformer (10) and hence the power delivered to a dehydrator (40) so as to prevent the step-up transformer (10) from exceeding rated power when a current limit occurs. The automatic voltage control system controls the voltage applied to the primary winding (12) so as to maximize the voltage applied to the grid elements (38) of the dehydrator (40). Upon encountering a current limiting condition, the automatic voltage control system reduces to zero the voltage applied to the primary winding (12) and hence the power applied to grid elements (38) of the dehydrator (40) to dissipate the cause of the current limiting condition. The voltage is reapplied to primary winding 12 at a voltage level below where the current limit occurred. The voltage is then increased to maximize the voltage applied to the grid elements (38) of the dehydrator (40). Upon encountering a voltage limit, the voltage is maintained at a constant level until either an arc or current limit are encountered whereupon the control cycle is repeated. | ||||||

| 160 | Apparatus for extracting polar substances from solution | US176518 | 1980-08-08 | US4319979A | 1982-03-16 | Arthur S. King |
| The extraction of polar substances, such as pure water, from a solution containing such substances is carried out in an electrical process that closely resembles natural evaporation.
