Title: Process for paraffin isomerization with liquid phase adsorptive product separation and with direct recycle of extract stream
Inventor: SCHMIDT ROBERT J
IPC: B01D15/08
Filed: 1991-06-20
Abstract: The efficiency and cost effectiveness of a combination of an isomerization process and a liquid phase adsorptive separation process is increased by the elimination of a column for the separation of desorbent material from selectively retained components thereby enabling direct recycle of the extract stream to the isomerization zone without intermediate fractionation. By decreasing the ratio of normal paraffin desorbent to the selective pore volume circulation rate, the extract column can be eliminated without providing other means for the rejection or recovery of desorbent material prior to recycle to the isomerization step. This reduction in the ratio of normal paraffin desorbent to selective pore volume circulation rate has been found not to decrease the recovery from the adsorption section. In an alternate arrangement, the extract column is replaced with a deisohexanizer column. The deisohexanizer containing column configuration can be used to produce a C5-C6 product stream having research octane numbers of 93 or greater.

Abstract: Optical integrated circuitry, performing various  of the functions associated with electronic integrated circuitry, is described. Fabrication, importantly to achieve high circuit chip density - typically in the range of 106 as including both devices and interconnecting guides - is dependent upon device/spacing dimension miniaturization resulting from fabrication in very thin layers.

Title: Screen generation for halftone screening of images using scan line segments of oversized scan lines
Inventor: LEVIEN RAPHAEL L
IPC: H04N1/23
Filed: 1992-09-21
Abstract: A halftone screen pattern generation system for computing halftone screened images with rotated screens including multiple angle and ruling combinations, including irrational tangent angles, is disclosed.  A screen pattern is generated by storing an oversized strip from an ideal angled screen pattern, and then assembling a sequence comprising selected scan line segments of the oversized strip.  Each selected scan line segment corresponds to one of a plurality of offsets of the oversized strip.  The error between the actual generated screen and ideal desired screen is computed.  Each subsequent scan line segment is selected from the plurality of scan line segments corresponding to the plurality of offsets so as to minimize the accumulated error.  In accordance with one aspect of the present invention, the measure of error between the actual generated screen and the ideal angled screen is the length of a vector in a transformed UV space between the actual screen sample point and the ideal screen sample point.  The error is determined by vector addition of the accumulated error, from scan line to scan line, which is added to the present error contribution from the offset of the present scan line.
