Inventor: BASTA JIRI J
IPC: D21C9/14
Filed: 1991-04-19
Abstract: The present invention relates to a process for delignification and bleaching of chemically digested lignocellulose-containing pulp for reduced formation and discharge of halogenated organic compounds, while preserving the pulp quality, where the prebleaching with halogen-containing bleaching agent is replaced by a treatment, in a first step, with the addition of a complexing agent at elevated temperature and at a pH from 3.1 to 9.0, and in a second step, by using a peroxide-containing compound under alkaline conditions, whereupon spent liquor from the final bleaching with halogen-containing compounds is recycled to the first or second step of the halogen-free prebleaching.

Title: Method of improving a digital image
Inventor: RAHMAN ZIA-UR
IPC: G06T5/20
Filed: 1997-05-08
Granted: 2003-03-27
Abstract: A method of improving a digital image is provided. The image is initially represented by digital data indexed to represent positions on a display. The digital data is indicative of an intensity value Ii(x,y) for each position (x,y) in each i-th spectral band. The intensity value for each position in each i-th spectral band is adjusted to generate an adjusted intensity value for each position in each i-th spectral band in accordance with where S is the number of unique spectral bands included in said digital data, Wn is a weighting factor and "*" denotes the convolution operator. Each surround function Fn(x,y) is uniquely scaled to improve an aspect of the digital image, e.g., dynamic range compression, color constancy, and lightness rendition. The adjusted intensity value for each position in each i-th spectral band is filtered with a common function and then presented to a display device. For color images, a novel color restoration step is added to give the image true-to-life color that closely matches human observation.

Title: Impregnation with black liquor prior to white liquor introduction
Inventor: RICHTER JOHAN C F C
IPC: D21C1/00
Filed: 1991-09-06
Granted: 2002-07-02
Abstract: A method of continuously digesting comminuted cellulosic fibrous material (e.g. wood chips) is provided which simultaneously improves uniformity of the end product and has substantial energy economy.      The chips are slurried, e.g. with black liquor, and fed to the top of a vertical digester. In the digester the chips are soaked in and heated with black liquor withdrawn from near the bottom of the cooking zone, which black liquor is at cooking temperature. White liquor (kraft cooking liquor) introduced into the cooking zone is preheated by passing it in heat exchange relationship with a portion of the black liquor withdrawn from the digester, so that only a small amount of heat in the form of steam need be added to the white liquor to bring it to cooking temperature. At the top of the digester, a portion of the liquid in the slurry can be withdrawn through a screen, pressurized, and then introduced under pressure with a downward velocity component facilitating a zone of concurrent movement of the chips and liquor.

Title: Closure button/panel energy enhancement
Inventor: VERCILLO PETER A
IPC: B65D55/12
Filed: 1991-10-03
Granted: 2003-04-01
Abstract: This relates to a closure cap having an end panel which is equipped with a central button or panel area so as to cause deflection, either by way of a vacuum within an associated container or by mechanical action when a container is closed. Recently, there has been developed a desire for a louder popping noise when the closure is removed. Also there has been developed tamper indicating indicia elements to be actuated by the button or panel area to irreversibly indicate that a container has been opened even though the closure cap has been reapplied. A need for a greater stored energy in the button or panel area has been found and such additional stored energy is obtained by utilizing faceted areas or portions.

Abstract: La méthode concerne l'application à un puits dévié d'un procédé connu de consolidation par polymérisation in situ d'une substance liquide injectée jusque dans une zone à consolider par un tube d'injection, par interaction avec un gaz G réagissant injecté à sa suite. Pour limiter la zone d'intervention et bien répartir la substance et le gaz sur toute cette zone, on utilise en combinaison un tube dont la paroi est pourvue d'ouvertures, sur toute sa partie terminale, un packer de confinement et un élément de séparation solide déplacé dans le tube à la suite de la substance liquide, par le gaz réagissant, qui empêche toute interaction de celui-ci avant qu'il ne parvienne à la zone à consolider. L'injection du mélange liquide comporte des phases successives de circulation entre l'intérieur du tube et l'annulaire entre lui et le puits et de forçage pour le faire bien pénétrer dans la formation. Elle est généralement précédée d'une phase d'injection de produits solvants.   Application à la consolidation de puits horizontaux produisant des effluents pétroliers.

Title: Serial data receiving apparatus
Inventor: NAGAMOTO SHUNICHI
IPC: H04L25/49
Filed: 1992-01-16
Granted: 1995-08-29
Abstract: This serial data receiving apparatus is intended to realize the receiving process of serial data having an inferior SN ratio with a simple arrangement and at low cost.  A one-bit length of the serial data is divided into several blocks.  The sampling data is input at multiple points of each block by using a shift register built in a microcomputer.  The data is temporarily held so that the data at the same number block of each block is accumulated for several bits.          The accumulation of the data results in cancelling the noise components and leaving the original signal components.  This overlapping type receiving system makes it possible to clarify the receiving phase of a preamble signal for bit synchronization and to establish the bit synchronization.  Next, the sampling data signals are entered at the multiple points based on the resulting receiving timing and the logic value of the bit is determined according to the ratio of the number of values of "1" to "0" contained in the data.  Further, by using the reversal symmetry of the first half and the second half of the bi-phase codes, it is possible to realize the methods for establishing bit synchronization and determining a logic bit more effectively and accurately.
