Patent CA-2234849-A1 (CA)
Inventor: BAYER GLEN H JR
IPC: D21H23/56
Filed: 1996-09-18
Abstract: A method of applying a coating of hot melt polymeric material from a die to a substrate. Hot melt polymeric material is extruded through the die onto the peripheral surface of a rotating application roller to provide a coating layer along that peripheral surface. A substrate is conveyed past the peripheral surface of the application roller at an application interface to cause transfer of the first coating layer to the substrate and shearing and thinning of the coating layer because the substrate is conveyed faster that the peripheral speed of the application roller. The velocity of the peripheral surface and spacing between the die and the application interface along are selected to provide a time inteval of at least 0.12 second for movement of portions of the coating layer from the die to the application interface, thereby affording relaxation and molecular reorientation of the hot melt polymeric material after the extruding step to facilitate shearing of the first coating layer at the application interface without causing ribbing or breaking of the coating layer.

Title: Efficient non-viral transduction and culture of erythroid cells
Inventor: BELL DAVID
IPC: C07K14/71
Filed: 1998-06-25
Abstract: The present invention involves 1) efficient non-viral gene transfer into human erythroid progenitors cells and 2) use of a constitutively active human EpoR  gene to prolong the lifespan of progenitor cells. CD34+ cells enriched from umbilical cord blood LDMNC are cultured ex vivo at a low density in the absence of supportive stroma for 7 to days in a serum-free defined culture medium with the addition of IL-3, SCF and EPO. At this time, cells expand < 70 fold and hematopoietic progenitors are present at a frequency of 25 BFU-E, 28 CFU-E and 10 CFU-GM per 1 x 10 5 cells as detected by methylcellulose colony forming assay. Approximately 2% are CD34+ while 40% are GlyA+. Hematopoietic cells cultured in this manner are rendered highly susceptible to gene transfer by electroporation and a gene transfer efficiency of >25% is obtained. The lifespan of erythroid progenitors that persist at the point of electroporation can be prolonged through the introduction of a constitutively active form of the human EpoR  gene.This invention is useful for (1) genetic modification of hematopoietic stem cells, especially erythroid progenitors and (2) the propagation of erythroid cells in vitro for the production of hemoglobin.

La réponse du système de commande se fonde sur le modèle de processus propre au système, lequel est fonction des données d'entrée provenant du détecteur ainsi que d'une ou de plusieurs techniques d'analyse de pointe, parmi lesquelles, mais sans que cette énumération soit limitative, l'usage d'ordinateurs neuromimétiques, les algorithmes génétiques, les logiques floues, les systèmes experts, l'analyse statistique, le traitement de signal, la reconnaissance des formes, l'analyse catégorique ainsi que leurs combinaisons. Parmi les paramètres de fonctionnement et d'exploitation d'intérêt particulier, figurent ceux relatifs à la cadence d'adjonction de produits chimiques (agents de floculation) et à leur quantité, à la consommation d'énergie, à la maîtrise des débits des solides/liquides d'évacuation ainsi qu'à celle de leur composition et à la commande du mécanisme moteur. Dans un mode de réalisation s'étant vu accorder une préférence particulière, l'appareil comporte un épaississeur ou analogue, pourvu d'au moins un détecteur produisant des données d'entrée consistant en un profil continu de la zone et du lit de décantation, profil analysé par un modèle de processus généré par des méthodes statistique associées à des ordinateurs neuromimétiques. Il découle de l'analyse qu'une sortie au moins peut être produite pour actionner un dispositif de commande effectuant des modifications sur des variables d'exploitation, telles qu'elles ont été proposées par le modèle de processus, ce qui entraîne un optimalisation du fonctionnement de l'épaississeur. Le ou les détecteurs sont, de préférence du type non invasif, un capteur ultrasonique (sonar) ou un détecteur radar à ondes millimétriques, par exemple.

Abstract: An intake and exhaust system for use with lean~burn combustion engines includes a first intake port and a second intake port that transfer a fuel~air mixture to a combustion chamber within a cylinder. At least one exhaust port allows combustion gases to exit the combustion chamber. Preferably, in the intake and exhaust system, a first exhaust port and a second exhaust port are located on diagonally opposite sides of the cylinder. The first intake port preferably transfers a fuel~air mixture to the combustion chamber in a direction opposite of the second intake port.
