Filed: 1999-03-18
Granted: 2000-11-11
Abstract: A monochrome image reading speed of an image reading apparatus can become faster by employing the following signal processing processes. In a case of a color image reading, individual color signals outputted from odd number pixels of a CCD line sensor and individual color signals outputted form even number pixels of a CCD line are multiplexed by the selector part with time-sharing, and are put into the A/D converters. And, in a case of monochrome reading, individual color signals outputted from odd number pixels of a CCD line sensor and individual color signals outputted from even number pixels of a CCD line sensor are selected as a dropout color by the selector part. And, they are converted to the digital signals by the different A/D converters. Then, the converted digital signals are put into a sequencer and are outputted as a row of data in succession. By employing the above-mentioned processes, a converting speed of the A/D converter in a case of monochrome reading where a reading speed is much faster than that of color image reading, does not need to be faster than a converting speed of the A/D converter in a case of a color image reading.

Title: Removal of soot in a gasification system
Inventor: JAHNKE FREDERICK C
IPC: B01D3/06
Filed: 1999-11-22
Granted: 2003-08-11
Abstract: The raw syngas generated in a partial oxidation gasifier also includes carbon soot which is removed and recovered from the syngas by scrubbing with water. The scrubbing water contains one or more high temperature surfactants which allow greater soot concentrations in the water-scrubbing quench zone of the gasifier. The carbon soot is separated from the scrubbing water with the aid of a scrubbing oil. The separation of the carbon soot from the scrubbing water is enhanced with the aid of one or more surfactants that render the soot particles hydrophobic and oleophilic. The recovered carbon soot is ultimately recycled to the gasifier to recover the energy value of the carbon during the partial oxidation reaction. The overall energy efficiency of the gasification process can be increased by removing all or a significant portion of the water from the soot mixture before recycling the soot. Separating the soot from the water allows for independent regulation of the soot and water recycle streams, depending on the reaction conditions in the gasifier.
