Title: Procede et equipement de blanchiment de pate a papier au moyen d'un reactif de blanchiment gazeux
Inventor: VLIET WALTER C
IPC: D21C9/153
Filed: 1996-07-16
Abstract: Méthode et appareil permettant de blanchir de la pâte au moyen d'un réactif de blanchiment gazeux. La pâte (18) est intensivement mélangée en présence du  réactif dans un récipient en amont comprenant un pelucheur/ventilateur (12). Ensuite, la pâte est agitée en présence du réactif de blanchiment dans un récipient intermédiaire comprenant un réacteur mélangeur agité (14). Elle est par la suite déversée dans un récipient en aval, lequel comporte un réacteur à support poreux (16) où elle est de nouveau mise en présence du réactif de blanchiment. Comme la concentration du réactif dans chaque récipient est régulée séparément et que le temps de traitement de la pâte dans au moins le réacteur mélangeur agité et le réacteur à support poreux est également régulé, il est possible d'économiser de l'énergie, de réduire au minimum le dommage causé aux particules de pâte dû à l'agitation mécanique et de blanchir la pâte uniformément.

Patent CA-2229301-A1 (CA)
Inventor: HOMAN EDWIN DARYL
IPC: E21B43/34
Filed: 1998-02-10
Abstract: A separator for separating gases, liquids and solids occurring in an affluent discharged from a well, the separator having characteristics which allow its use in a number of different applications, including in-line testing, underbalanced drilling, and frac flow in bringing a well into production or the restoring of an old well. An interior separating device permits the escape of gas through a gas outlet tube to the upper portion of a chamber in a closed vertically disposed vessel. A lower discharge portion of the separating device is received in a tubular confinement member the lower end of which is below the operating level of liquid collected in a lower portion of the chamber in the vessel. A plurality of upstanding vanes is located in a solids collection chamber below an open lower end of the confinement member, the solids collection chamber having a solids outlet in a lowermost location. Above the gas outlet tube and a gas demister through which gas exiting from the chamber passes is a tray having an upper liquid collecting surface. A liquid outlet permits exit of the liquid as it collects in the chamber, the exiting liquid passing through a sand removal device which deposits sand suspended in the liquid to the solids collection chamber. While the separator is of relatively simple construction and is therefore economical to produce and of a size which may be readily transported, its versatility eliminates the necessity of providing and transporting a number of different types of separators for different operating conditions.

Title: Analyzing system
Inventor: MUNETAKA KEISUKE
IPC: G01N35/00
Filed: 1998-05-19
Abstract: In an inventive analyzing system (e.g. liquid chromatograph), an analyzing schedule includes data on whether or not to carry out a self-check for each sample, and data on what process to follow the self-check according to the check result, in addition to data on the analyzing order and analyzing condition of a series of analyses on a plurality of samples. In carrying out the analysis according to the schedule, a self-check is carried out after an analysis of a sample for which the self-check is scheduled. In the self-check, a data collecting unit 17 collects data on the degree of degradation of expendable parts and on the wavelength error of a spectrophotometric detector 14, etc., and a checking unit 18 detects abnormality by comparing the data to preset tolerable values. For example, in the case where the process specified to follow the detection of abnormality is "stop analysis on detecting abnormality", a control unit 15 stops each part of the system so that the rest of the analyses are deferred.

Title: A method of coding and decoding audio signals
Inventor: KUNZ OLIVER
IPC: H04B1/66
Filed: 1996-11-21
Abstract: A method of encoding time-discrete audio signals comprises the steps of weighting the time-discrete audio signal by means of window functions overlapping each other so as to form blocks, the window functions producing blocks of a first length for signals varying weakly with time and blocks of a second length for signals varying strongly with time. A start window sequence is selected for the transition from windowing with blocks of the first length to windowing with blocks of the second length, whereas a stop window sequence is selected for the opposite transition. The start window sequence is selected from at least two different start window sequences having different lengths, whereas the stop window sequence is selected from at least two different stop window sequences having different lengths. A method of decoding blocks of encoded audio signals selects a suitable inverse transformation as well as a suitable synthesis window as a reaction to side information associated with each block.

Title: Low-profile automatic injection device with self-emptying reservoir
Inventor: CONNELLY ROBERT I
IPC: A61M5/142
Filed: 1999-02-10
Abstract: A device for delivering a liquid therapeutic preparation into the body of a patient by injection into or through the skin of the patient comprises a low-profile housing having a bottom surface adapted to be brought into contact with the skin of the patient. A reservoir is disposed within the housing for containing a liquid therapeutic preparation to be administered. An injection needle is disposed generally horizontally in the housing, and is adapted to communicate with the reservoir. The injection needle has a bent injection end which is adapted to project through a needle aperture in the bottom surface of the housing. A movable needle carrier is disposed in the housing for carrying the injection needle and for causing the injection end of the needle to project through the needle aperture upon movement of the needle carrier. The needle carrier and the injection needle are disposed in a side-by-side relationship with the reservoir in the housing in order to minimize the height of the housing above the bottom surface. As a result, the housing is sufficiently low in height to allow the device to be worn inconspicuously under the clothing of the patient.

The transmitter transmits data over a spread-spectrum channel, along with a spread-spectrum channel having little or no information, i.e., an equalization channel to the receiver. The receiver includes an antenna (357), a QPSK  demodulator (390), an in-phase subsystem (61), a quadrature-phase subsystem (62), and a processor (385). The receiver uses in-phase early, punctual and late signals, and quadrature-phase early, punctual and late signals, for equalizing of the data spread-spectrum channel, and for generating an output in-phase data signal and an output quadrature-phase data signal.
Patent CA-2264634-A1 (CA)
Title: Temperature compensating system for fluid-damped suspension systems
Inventor: BALDOMERO RICARDO R
IPC: F16F9/52
Filed: 1998-06-29
Abstract: A temperature compensating system (10) for a closed system, such as damping system (12), in which fluid is subject to temperature increases and acocmpanying volume increases. The temperature compensation system provides a compressible member (40) within a temperature compensation volume, and a barrier (46) restricting the entry of fluid to the volume. When the fluid volume increases as a result of temperature increases, fluid seeps past the barrier into the temperature compensation volume to compress the compressible member and thus increase the total volume available to the fluid in the closed system. The increased volume reduces pressure buildup that would otherwise occur, and thereby tends to maintain a steady pressure within the closed system. Dynamic or high speed fluid flows are restricted by the barrier or other restriction, inhibiting such flows from passing into the volume. The barrier or other restriction thus tends to prevent the temperature compensating system from interfering with normal functioning of the system while maintaining a steady internal pressure therein.
