| 20100300938 | PROCESS FOR OXIDATIVE CONVERSION OF ORGANOSULFUR COMPOUNDS IN LIQUID HYDROCARBON MIXTURES - The process for the desulfurization of a sulfur-containing hydrocarbon mixture, such as a full-range, hydrotreated diesel oil, is accomplished with an aqueous oxidizing agent in the presence of a catalyst and a co-catalyst, and thereafter selectively removing the oxidized compounds by solvent extraction. Optionally, the foregoing steps are followed by solvent stripping and recovery, and a final polishing step. | 12-02-2010 |

| 20110213187 | HYDROCARBON RECOVERY FROM SULFONES FORMED BY OXIDATIVE DESULFURIZATION PROCESS - The process provided herein is concerned with recovery of hydrocarbons from sulfones using an individual alkali and alkaline-earthy base and a mixture of thereof. As the starting materials are sulfones generated by ODS and commercially inexpensive alkali and alkaline-earth bases, the cost and ecological impact of solid waste disposal is minimized. | 09-01-2011 |

| 20100327931 | Wideband programmable phase shifting circuit - The wideband programmable phase shifting circuitry includes a charge pump, a comparator, and a voltage reference generator block. An input signal controls the charge pump which charges and discharges a capacitor connected to an output of the charge pump. The comparator continuously compares the voltage across the capacitor with a reference voltage, ratio of V | 12-30-2010 |
