Patent CA-2381724-A1 (CA)
Title: Extruder screw
Inventor: ZBORIL VACLAV GEORGE
IPC: B29C48/41
Filed: 2002-04-12
Abstract: The capacity of an extruder fed with a high viscosity liquid having a volatile component may be limited by the ability of the high viscosity liquid to completely fill the flights of the screw in the barrel o f the extruder. The liquid may incompletely fill the initial sections of the screw and may be subject to a partial or complete vapour lock. This problem may be reduced by using a screw having in the section adjacent the feed port an increasing flight volume from the back to the front of the feed port. It may also be reduced in combination or independently through the use of guide vanes or baffles placed in an appropriate position of the extruder feed port.

Title: Process for manufacturing granulated hydrophilic resin
Inventor: AKAO TOSHIKAZU
IPC: B29B9/04
Filed: 2002-04-29
Abstract: Granulated hydrophilic resins are manufactured by: an extrusion step to melt and extrude a hydrophilic resin; a cooling step to obtain a solidified resin by solidifying with cooling thus extruded resin through the contact with a metal plate; and a granulating step to obtain a granulated hydrophilic resin by the granulation of thus solidified resin. Thus resulting granulated hydrophilic resins can be used for the extrusion molding and the like.

IPC: G06F17/50
Filed: 2000-09-18
Abstract: L'invention concerne un procédé et un dispositif permettant d'analyser un flux de liquide tout en considérant les effets de transfert de chaleur, en particulier un changement de phase entre l'état fondu et l'état solide. On peut ainsi intervenir en particulier pour analyser un processus de moulage par injection visant à réaliser un composant polymère moulé à partir d'un polymère thermoplastique ou thermodurcissable. Selon une variante, le procédé permet de déterminer la pression requise pour remplir une cavité de moulage et les gradients de pression introduits durant le remplissage et le tassement de la cavité d'un moule à injection. Il est possible d'utiliser les résultats de ce type d'analyse pour déterminer le nombre et l'emplacement de grilles, déterminer le meilleur matériau pour le composant et optimiser les opérations durant le processus de moulage.

Title: Coating with optical taggent
Inventor: WHITE MICHAEL L
IPC: C09D7/00
Filed: 2000-09-06
Abstract: A method for determining the thickness of a dryable or curable film-forming coating by incorporating a fluorescent component into the coating. The fluorescent component is either a resin solid of the coating, a fluorescent dye or a fluorescent dye attached to a resin solid of the coating. The coating is exposed to ultraviolet or visible light which causes the fluorescent component to fluoresce. The intensity of the fluoresce of the coating is measured and the thickness or weight of the coating is determined from a known mathematical relationship between the fluorescence intensity of the coating when exposed to the light and the thickness or weight of the coating. Additionally, a curable or dryable film-forming coating composition including a curable or dryable organic resin reacted with a fluorescent tag is provided.

Patent CA-2400782-A1 (CA)
Inventor: FOSTER RAYMOND KEITH
IPC: B65G25/04
Filed: 1997-04-09
Abstract: In a reciprocating slat conveyor, at least three slat sets of at least one slat (CS) each are driven by piston-cylinder drive units (26), one for each slat set.  Each drive unit (26) is provided with a four-way proportional directional control (PDC) valve. Each PDC valve has a first position of adjustment in which it connects a first working chamber of its drive unit (26) to pressure (B) and a second working chamber to tank (T), and a second position of adjustment in which it connects the second working chamber to pressure (P) and the first working chamber to tank (T). Control logic (96) provides electrical control signals for directing the PDC valves to operate the drive units to advance more than half of the slat sets simultaneously in a first, conveying direction, and to retract the remaining slat sets in the opposite direction at a higher rate of speed. A controller compares the control logic signals with feedback signals generated by a separate linear position sensor PS for each slat set. The controller compares the desired positions of the slat sets, as determined by the control logic (96), with the actual positions of the slat sets, as determined by the position sensors PS. The difference between the desired and actual positions of the slat sets is used to generate a corrected control signal which the controller sends to proportional amplifiers (PA). The proportional amplifiers (PA) provide control signals to the PDC valves, for changing the rate of hydraulic fluid movement into and out from the working chambers of the drive units (26) for the advancing conveyor slat sets, towards establishing the desired pattern of movement of the slat sets. The conveyor includes a drive module comprising a pair of longitudinally spaced apart end frame members, each extending transversely of the conveyor, and a center frame member positioned longitudinally between the two end frame members, and also extending transversely of the conveyor. A first pair of piston-cylinder drive units extends longitudinally of the conveyor, between a first said end frame member and the center frame member. The second pair of piston-cylinder drive units extends longitudinally of the conveyor between the center frame member and the second end frame member. The drive units are connected at one or both ends to one of the frame members. Each drive unit has a movable portion that is positioned between the center frame member and one of the end frame members. Two transverse drive beams are positioned between the first end frame member and the center frame member. The remaining two transverse drive beams are positioned between the center frame member and the second end frame member. Each transverse drive beam is connected to the movable portion of a separate related one of the drive units. Each transverse drive beam is also connected to a separate set of the conveyor slats.

IPC: C12Q1/68
Filed: 2001-03-28
Abstract: L'invention concerne une méthode de détection de séquences d'ADN spécifiques et de discrimination de polymorphismes mononucléotidiques (SNP) utilisant des sondes oligonucléotidiques à marquage fluorescent. Les sondes oligonucléotidiques sont marquées à l'aide d'une molécule reporter attachée préférentiellement à un résidu nucléotidique interne. L'émission fluorescente de sondes oligonucléotidiques varie considérablement dans des états monocaténaires et bicaténaires, malgré l'absence de groupes fonctionnels d'extinction, permettant la détection fiable de cibles d'ADN complémentaires. La température de fusion de doubles hélices sonde/cible permet la discrimination de cibles qui diffèrent d'aussi peu que d'un résidu mononucléotidique, de sorte que des cibles polymorphes peuvent être discriminées par quantification fluorescente et Tm. Selon l'invention, il est démontré que les sondes d'hybridation identifient avec précision des échantillons homozygotes et hétérozygotes en utilisant un oligonucléotide à fluorescence simple, et l'analyse directe de la salive à l'aide des sondes d'hybridation permet une analyse génotypique ultra-rapide en 35-45 minutes. Les dosages de détection de cibles et discrimination SNP ont été réalisés en 'temps réel 'homogène hétérogène, et dans des formats en phase solide.
