Title: Process for the preparation of cooking liquors having high sulphidity for sulphate pulp cooking
Inventor: HEDBLOM MATS-OLOV
IPC: D21C11/04
Filed: 1990-11-21
Abstract: An improvement is provided in a process for preparing, under reducing conditions, cooking liquors for sulphate pulp cooking. The black liquor which is formed in the cooking process is fed, after evaporation, completely or partly to a reactor operating at increased temperature. The increased temperature is obtained by energy which is supplied from an external heat source and/or release of energy from the black liquor, thereby to form a melt of sodium sulphide. The melt then is withdrawn to be further processed to cooking liquor. The melt, and the whole or part of at least one of sulphur-containing, sulphur-and sodium-containing materials which are present in the pulp mill including sulphur-containing, and sodium- and sulphur-containing make-up chemicals used for the total chemicals balance of the pulp mill, are fed to the reactor in such a way that the mole ratio of sodium to sulphur in the total mixture which is fed to the reactor is within the range of from 1.5 to 4.

IPC: G03B27/73
Filed: 1991-09-13
Abstract: Un opérateur de traitement d'images à développement-tirage détecte les défauts de performance d'un mécanisme d'équilibrage de scène sur une image numérisée et permet au développeur-tireur de corriger ces défauts de façon interactive avant que l'image défectueuse ait été traitée et qu'une image de sortie inacceptable ait été imprimée.  Chaque fois qu'une image défectueuse est détectée, une ou plusieurs versions de l'image à résolution raisonnablement basse, traitée par le mécanisme d'équilibrage de scène, est affichée pour le développeur-tireur, avec une demande d'information d'ajustement d'image servant à modifier ou à corriger l'équilibre des couleurs de l'image.  En réponse à cette information entrée par l'utilisateur, le processeur d'images règle les paramètres d'équilibre des couleurs du mécanisme d'équilibrage de scène, de sorte que l'image numérisée traitée par le mécanisme d'équilibrage de scène modifié donne une épreuve dont la qualité d'équilibrage des couleurs est acceptable.  L'interaction de l'opérateur de développement-tirage et du système de traitement des images peut s'effectuer selon plusieurs modes, y compris l'affichage de versions d'image traitées différemment, ou d'une seule version de l'image traitée par le mécanisme d'équilibrage de scène, avec une question concernant le type d'image.  Le mécanisme de détection de défauts emploie de préférence un discriminateur non linéaire, comme un réseau neuronal.
Patent CA-2075679-A1 (CA)
Inventor: DAVIS ROBERT W
IPC: B60J10/00
Filed: 1992-08-10
Abstract: The opposite edge portions and the center portion of a continuous strip of sheet metal are progressively sheared with longitudinally spaced and laterally extending slits to form opposing U-shaped tabs having corresponding edge portions and successively connected by corresponding center portions of the strip. The sheared strip is fed between first and second overlapping sets of power driven pinch rollers which progressively grip the edge and center portions, respectively, and the second set of pinch wheels is longitudinally offset and driven at a higher peripheral speed to produce precisely uniform expansion of the strip by deforming the U-shaped tabs into U-shaped tabs. A hot melt adhesively impregnated flexible filament is progressively attached to the expanded portions of the strip while the strip is heated, and the expanded strip is progressively formed into a channel which is fed into an extrusion head for producing a reinforced rubber-like weatherstrip.
Patent CA-2076341-A1 (CA)
Title: Vertical tower evaporation utilizing dimpled plates
Inventor: ELMORE CARL L
IPC: B01D3/06
Filed: 1992-08-18
Abstract: ABSTRACT    A multi-stage evaporator assembly includes one or more vertical concrete circular towers having a number of vertically spaced, distinct evaporator effects.  The effects are separated by demistors. Normally the first effect of a tower is at the bottom and the last effect at the top so that salt water to be evaporated flows downwardly under gravity from one effect to the next, and vapor flows upwardly through the demistors from one effect to the next. Alternatively, every alternate tower may have its first effect at the top and its last effect at the bottom so as to minimize the vapor conduit length from the previous tower.  The towers may be partially submerged in the earth to minimize the possibility of damage from earthquakes.  The towers are typically associated with a surface condenser, a product flash tank, and a brine flash tank.  The product flash tank has a chamber connected to the condensate discharge from each of the effects except the first effect, and the vapor from the flash tanks is returned to the effects to recover the heat value of the flashed fluid.

Title: Solid state ion sensor with silicone membrane
Inventor: BROWN RICHARD B
IPC: G01N27/414
Filed: 1991-05-02
Abstract: A silicone matrix is employed to form a substance-sensitive membrane which is particularly suited for installation on a solid state sensor. The ionophore may be a potassium ionophore, an ammonium ionophore, or any other ionophore. The membrane may be coupled to the molecule of interest through a bioactive agent, such as an enzyme, an immunochemical, bacteria, antibody, virus, or antigen.  The resulting substance-sensitive membrane has electrochemical properties which compare favorably to those of conventional PVC  membranes, and exhibit significantly greater adhesion to glasses and semiconductor substrate materials. The improved adhesion will prolong the life of the sensors and prevent the formation of electrolyte shunts which have been known to render solid state sensors inoperative.

Title: Communication transfer in a radiotelephone system
Inventor: FELIX KENNETH A
IPC: H04W36/30
Filed: 1991-08-16
Abstract: A cellular system transfers a call from a source base-site (200) to one target base-site (205, 210). A source base-site (200) measures the signal strength (RSSIS) of a mobile (225), provides a forecasted signal strength (RSSIF) and sets up two time windows. The source base-site (200) sends the measured and forecasted signal strengths to candidate base-sites (205, 210) found by the mobile (225) which measure the mobile (225) signal strength (RSSIT) and compare it to (RSSIS + hysteresis value). If RSSIT> RSSIS, the call is transferred to the best responding cell. If RSSIT< RSSIS, RSSIT is compared to RSSIF. During this time, the mobile (225) will increase power at the end of the first time window. If RSSIT> RSSIF at any candi-date base-sites (205, 210), the call is transferred to the responding base-site (205, 210). If the source base-site (200) receives no responses during the second time window, the process ends.
