Abstract: A polyamide substrate having deposited thereon a copolymer effective to impart resistance to staining by turmeric wherein said copolymer comprises polymer units derived from (a) at least one cyclic olefin having from 5 to 12 carbon atoms, and (b) maleic anhydride wherein the molar ratio of total cyclic olefin to maleic anhydride is between about 0.5 and 1.3, and a method for using the copolymer to impart stain resistance to a polyamide substrate.
Abstract: When processing a signal having a sequence of discrete values, wherein there is a first frequency range, in which the signal has a high energy, and wherein there is a second frequency range, in which the signal has a low energy, the sequence of discrete values is first manipulated to obtain a sequence of manipulated values, so that at least one of the manipulated values is non-integer. Then the sequence of manipulated values is rounded to obtain a sequence of manipulated values. The rounding is formed to effect a spectral shaping of a generated rounding error so that a spectrally shaped rounding error has a higher energy in the first frequency range than in the second frequency range. By spectrally shaping the rounding error so that the rounding error does not have any energy either in the storage areas where there is no signal energy, an especially efficient coding is obtained particularly in connection with a lossless coding context.

Abstract: The present invention provides a method for recovering oil from a subterranean reservoir using waterflooding, wherein the flooding fluid used in the waterflooding process comprises water and one or more ionic polyvinyl alcohol copolymers. The use of one or more ionic polyvinyl alcohol copolymers is expected to increase the recovery of oil by improving both the oil/water mobility ratio and the sweep efficiency in reservoirs with a high degree of heterogeneity.

Abstract: The present invention provides a process for making a filled fluoropolymer bearing comprising providing an aqueous fluoropolymer dispersion comprising fluoropolymer particles and anionic polyelectrolyte dispersing agent in an amount sufficient for stabilization. The dispersion contains less than about 300 ppm fluorosurfactant based on the weight of the dispersion. The dispersion is coagulated to make a mush and a bearing filler is added to the dispersion prior to or after making the mush. The mush containing bearing filler is applied onto a bearing substrate to produce a coated substrate which is sintered and formed into a bearing.

Abstract: The invention relates to image sensors using a chip with cut corners. The sensor comprises a chip with cut corners comprising a matrix (10) of horizontal lines and vertical columns of photosensitive members, the matrix having a generally rectangular shape of horizontal width W and having four bevels, the sensor comprising as many current or voltage read blocks as there are matrix columns, in order to read the image signals detected by the photosensitive members, characterized in that the current or voltage read blocks are placed in a row (30, 30?) along a horizontal edge of the matrix of width W? and are all housed within a vertical strip, the width W1 of which is substantially less than the maximum width W of the matrix. There are two superposed rows of current read blocks with blocks distributed at the same pitch as the pixel columns, or there is a single row with read blocks distributed with a pitch less than that of the pixel columns.

Abstract: An electronic device can include an organic device layer having a first and a second portion. In one embodiment, the first portion can have a higher resistivity than the second portion and lie between a first and a second electrode and include not more than 15 mole percent basic material. In a particular embodiment, the first and the second electrode can be an anode and cathode of a pixel. In another particular embodiment, the first and the second electrode can be either both anodes or both cathodes of different pixels. In another embodiment, the organic device layer can include a large molecule material. In still another embodiment, a process of forming the electronic device can include selectively modifying the first portion of the organic device layer.
Abstract: The invention relates to the isolation and characterization of a maize gene, RAMOSA3 (RA3), responsible for meristem development and inflorescence development including branching. The gene, gene product, and regulatory regions may be used to manipulate branching, meristem growth, inflorescence development and arrangement, and ultimately to improve yield of plants. The invention includes the gene and protein product as well as the use of the same for temporal and spatial expression in transgenic plants to alter plant morphology and affect yield in plants. The invention also includes the gene and protein product for SISTER OF RAMOSA3 (SRA).

Abstract: A multipass printing method is characterized in that, on any given pass, the number of selected print locations onto which printing ink is deposited by each of N nozzles varies from nozzle to nozzle. The variation is governed in accordance with a weighted smoothing spline function, particularly a polynomial B-spline function of the order “j”, where j is a value equal to one less than the number of passes.
