20110245355 | CATALYSTS - A process for regenerating a spent particulate wax-containing cobalt-based Fischer-Tropsch synthesis catalyst is provided. The process includes subjecting the spent wax-containing catalyst sequentially to a dewaxing treatment, an oxidation treatment and a reduction treatment. During the dewaxing treatment, the spent wax-containing catalyst is at least partially dewaxed, with dewaxed catalyst particles being produced. During the oxidation treatment, an oxygen-containing gas is passed through a bed of the dewaxed catalyst particles at an operating temperature T° C. where 15010-06-2011 | |

20140253032 | CAPACITIVE SENSING ENABLED SWITCH MODE POWER SUPPLY AND DATA TRANSFER - A microchip for control of a switch mode power supply (SMPS), with said microchip also having the ability to measure capacitance of an electrode or sense plate structure or structures, and use of a low power, power supply structure to supply said microchip, said power supply structure distinct from the main energy path via said SMPS to a load. The microchip may control said SMPS to transition between an active state and an inactive state, with the measured capacitance used to determine a condition for state transition. In said SMPS inactive state, only the microchip draws power to operate its capacitive sensing circuitry, leading to a significant SMPS standby losses decrease compared to prior art. Further teachings by the present invention include capacitive sensing based data transfer, universal charging platforms for mobile devices, noise immunity enhancements, various lighting embodiments as well as SMPS operation improvements. | 09-11-2014 |
