摘要:
What is disclosed is a novel system and method for reducing a size of a memory buffer used by an electronic registration correction system performing an electronic registration correction on a digital image. The present method uses column address segmentation to identify blocks of scanlines within a spatially mapped array of image pixels comprising a digital image. Advantageously, the present system and method reduces scanline buffer memory by a factor of 2n-1, where n is the number of column address segments. Buffering can be performed at almost any upstream location in the image path. The present method is well suited for high resolution imaging equipment where memory is constrained by design, cost, or space limitations.

Disclosed are FIFO type methods, systems and apparatus for electronically registering image data relative to a raster or other marking device. According to an exemplary method, a FIFO type data queuing configuration is provided, where the length of data memory segments associated with the FIFO are selected to correspond to the number of raster lines from the most upstream point of the physical raster to the point where the given pixel column intersects the physical raster.

Disclosed are FIFO type methods, systems and apparatus for electronically registering image data relative to a rastering device or other marking device. According to an exemplary method, a FIFO type data queuing configuration is provided, where the length of data memory segments associated with the FIFO are a function of a spatial profile associated with the ink jet rastering device.

A honeycomb substrate includes an inner body having an inner skin and an array of inner webs defining an array of inner cells within the inner skin. The honeycomb substrate further includes an outer body having an outer skin formed concentric with the inner skin and an array of outer webs defining an array of triangle cells between the inner skin and the outer skin. The triangle cells are oriented along a radial direction with respect to a center of the inner body. An extrusion assembly for forming the honeycomb substrate includes an inner cell forming die, an outer cell forming die, and a skin forming mask, all mounted coaxially. An outer skin slot formed between the outer cell forming die and the skin forming mask is in communication with feedholes in the inner cell forming die through an opening in the outer cell forming die.

The invention relates to a method for conversion of methanol, ethanol alone or in combination with n-propanol to the corresponding isoalcohols by contacting a catalyst of a noble metal supported on at least a first phase of mixed oxide crystallites containing from about 60 to about 74 atomic % (on a metals basis only) zirconium, from about 21 to about 31 atomic % manganese and from about 5 to about 9 atomic % zinc, and less than about 1 atomic % alkali, a second phase of zirconium-doped hetaerolite particles containing from about 65 to about 69 atomic % manganese, from about 31 to about 35 atomic % zinc, from about 0.5 to about 5 atomic % zirconium, and optionally a trace atomic % of alkali, and a third phase containing from about 29 to about 55 atomic % manganese, from about 13 to about 55 atomic % zinc and from about 13 to about 35 atomic % zirconium, wherein the first phase mixed oxide crystallites have a zirconium oxide-like structure have a particle size of at least about 40 .ANG. to about 100 .ANG., the second phase particles have a particle size of about 200 .ANG. to greater than about 2000 .ANG., and the third phase has a particle size of about 1000 .ANG. to greater than 4000 .ANG., with reactant stream containing a light olefin selected from the group consisting of ethylene, propylene and mixtures thereof and synthetic gas and optionally methanol to produce a product stream containing the corresponding isoalcohols. Isobutanol in particular may be produced when the feedstream contains methanol in combination with one or more of ethanol, n-propanol, ethylene and propylene.
