Abstract: A process is provided herein for peroxide bleaching of pulp using magnesium oxide or magnesium hydroxide as a substitute for caustic soda. The process includes the first step of treating pulp using a peroxide bleaching solution comprising a peroxide and at least one of magnesium oxide and magnesium hydroxide. The process includes the next step of maintaining the concentration of Mn to less than 10 ppm and the concentration of Fe to less than 20 ppm by selecting a chelating agent and adding the selected chelating agent to the peroxide bleaching solution in accordance with the following criteria, namely (a) monitoring a concentration of Mn in the peroxide bleaching solution and, when the Mn concentration is greater than 10 ppm, adding a chelating agent which is selected from the group consisting of DTMPA, DTPA, EDTA and HEDTA, and (b) monitoring the concentration of Fe in the peroxide bleaching solution and, when the Fe concentration is greater than 20 ppm, adding a chelating agent which is selected from the group consisting of an alkali, metal silicate and DTPMPA. In this way, a maximum target ISO  brightness of 80 is achieved.

Granted: 2007-04-03
Abstract: A connection manager which provides communications control in a server of a server client system permits a client node to establish rudimentary communications with a designated server port and then moves the connection to a communications port specific to the application running on the server. The specific communications port is then configured by the communications manager with the protocol drivers required by the client node. An application may be displayed in an HTML page. In one embodiment, the same data can be transmitted substantially simultaneously from an application executing on a server node to at least two client nodes. A server node in a client server system may download and executes application written in interpretive languages on behalf of associated client nodes.

Title: Method for sterilizing an endoscope
Inventor: FOURNIER STEPHANE
IPC: A61L2/20
Filed: 2000-02-11
Granted: 2006-05-16
Abstract: A method of sterilizing a hollow endoscope having a conduit is disclosed. An end of the endoscope conduit is connected to a sealed vessel such that the endoscope conduit is in fluid communication with the sealed vessel. The endoscope is placed in a sterilisation chamber and the chamber sealed. The sterilisation chamber is run through sterilisation cycles in which the pressure within the chamber is varied.  During the pressure variation within the sterilising chamber, sterilising gas is drawn from the sterilising chamber via the endoscope conduit into the vessel. During the pressure variation the inner surface of the endoscope is subjected to sterilising conditions in addition to the outer surface of the endoscope. In a preferred embodiment the sterilising conditions are provided for by ozone gas in the presence of a humid atmosphere of at least 95 % water saturation. The sterilization process is operatively simple and reduces the chance of human errors caused by false interpretation and handling. The ozone sterilization method of the invention requires substantially no aeration or cooling down of sterilized instruments so that they can be used immediately following the sterilization cycle. The present invention permits hospitals to reduce the costs associated with maintaining an expensive endoscope inventory.

Title: Dynamic range extension of wideband receiver
Inventor: LI BIXIA
IPC: H04B1/28
Filed: 2000-10-23
Granted: 2004-07-20
Abstract: A digitizer with increased dynamic range is provided by applying varying gains/attenuations to an input signal and feeding the resulting scaled signals to several conventional analog-to-digital converters to be digitized. The digitized version of the largest scaled signal which does not result in its respective analog-to-digital converter from saturating is selected by a multiplexer to be fed through as the digitizer output. Each of the gains(attenuations) differ by multiples of approximately 6 dB, since one bit in an ADC represents this value. The multiplexer outputs a digital sample size which is larger than that of the analog-to-digital converters and with the selected digitized version being output as the appropriate subset of the larger sample size to account for the gain(attenuation) of the selected signal. Preferably, this is used in a wideband receiver to increase the dynamic range of the receiver.

Abstract: L'invention porte sur un générateur acoustique (301, 401) (301, 401) qui transmet des contraintes vibratoires à un milieu de propagation de signaux tel qu'un tube de production de puits de pétrole lorsqu'on l'actionne avec un entraînement électrique. Dans une exécution, le générateur acoustique (301, 401) (301, 401), qui utilise un entraînement mécanique comportant des éléments piézo-électriques (304) produisant les contraintes vibratoires, n'est relié au milieu de propagation qu'en un seul point, choisi pour empêcher de charger le générateur acoustique (301, 401) (301, 401) par les forces de compression et de traction véhiculées par le milieu de propagation. On peut utiliser une masse (406) assistant entraînement mécanique pour étendre la plage de fréquences de fonctionnement du générateur acoustique (301, 401). On peut par ailleurs réduire la fréquence de résonance du générateur acoustique (301, 401) au moyen d'un amortisseur (409) visqueux conçu pour se coupler à l'entraînement mécanique lorsque le générateur acoustique (301, 401) fonctionne, et sinon s'en découpler.

Abstract: L'invention porte sur des particules abrasives de diamant qui sont préparées à partir d'un diamant synthétisé sous une pression statique extrêmement élevée. Ces particules présentent une structure sensible à la chaleur, formée par traitement thermique à 1000 ·C ou plus, et constituent un agrégat non agglomérant de fines particules individuelles cristallines de diamant dont le diamètre moyen (valeur D 50) est inférieur ou égal à 5 µm et dont l'enrobage superficiel est de 0,5 % en masse par rapport à la totalité de la particule d'un carbone exempt de diamant. L'invention porte également sur un procédé de préparation de particules abrasives de diamant modifiées qui se caractérisent en ce que leur diamètre moyen (valeur 50 D) est supérieur ou égal à 50 nm. Selon ce procédé, ces particules sont traitées thermiquement à une température de 1000 ·C ou plus dans une atmosphère non oxydante ou sous vide de sorte que leur surface soit partiellement transformée en un carbone exempte de diamant. Le procédé de préparation des particules abrasives de diamant précitées permet d'obtenir des particules abrasives d'un type cristallin, unique, fin, qui sont préparées à partir d'un diamant synthétisé sous une pression statique extrêmement élevée, et qui, en dépit de cela, répondent aux exigences suivantes concernant des grains abrasifs destinés à être utilisés dans le traitement des boues: (1) une grande quantité de matière peut être traitée dans une unité de temps, (2) la rugosité d'une surface traitée est faible, et (3) lorsqu'on traite un matériau mou, le nombre de grains abrasifs restant sur une surface traitée est faible.

Abstract: Employed as a structure of a highly nonlinear optical fiber (nonlinear optical fiber) is a double-cladding structure in which a first cladding region 20 and a second cladding region 30 are disposed on the outer periphery of a core region 10. Since the double-cladding structure is employed, the cutoff wavelength .lambda.c can sufficiently be shortened even when, in order to increase the nonlinear coefficient .UPSILON., the concentration of GeO2 added into the core is enhanced so as to raise the nonlinear refractive index, or the relative refractive index difference between the core and cladding is increased so as to reduce the effective area A eff. This realizes an optical fiber or nonlinear optical fiber shortening its cutoff wavelength while having a sufficient nonlinearity, an optical amplifier and wavelength converter using the same, and a method of making an optical fiber.
