Patent CA-2512804-A1 (CA)
Title: Tickler for slurry reactors and tanks
Inventor: COPE RICHARD F
IPC: B01F23/00
Filed: 2004-01-16
Abstract: The present invention is directed to a tickler impeller and agitation system for use in stirred slurry reactors and storage tanks. The tickler impeller when mounted on a shaft is effective for providing an inward and downward swirl in a slurry medium which directs solids suspended in the slurry towards the bottom of the tank and towards the shaft on which the impeller is mounted.  Directing solids suspended in a slurry downwards and toward the center of the tank rather than pushing those solids away from the center reduces solid deposits on the side of the tank, facilitates draining of the tank, and reduces nozzle starving and pump starvation.

Inventor: SCHEWE SCOTT
IPC: B29C48/33
Filed: 2004-01-14
Abstract: L'invention concerne un appareil (20) et un procédé qui permettent de mouler des cathéters à ballonnet. Pour mouler le ballonnet (34), on peut préparer un tube polymère (36) dans un moule (24) pourvu d'une cavité intérieure (46) sous la forme du ballonnet souhaité. L'énergie micro-onde, qui peut être générée par un gyrotron (124), peut ensuite être dirigée sur le moule afin de chauffer le matériau polymère sans chauffer le moule. Une fois chauffé, le fluide pressurisé peut être injecté dans le tube afin de projeter le matériau polymère contre la cavité intérieure, ce qui permet au matériau de se refroidir afin de former le ballonnet ou d'être thermofixé par un supplément d'énergie micro-onde et peut être refroidi afin de former le ballonnet. Selon un mode de réalisation, l'énergie micro-onde peut également être utilisée sans moule afin de former un dispositif médical. L'invention concerne également un appareil d'extrusion de polymère utilisant une énergie micro-onde afin de chauffer un matériau d'alimentation polymère dans la pointe d'extrusion et dans l'extrudeuse, juste avant la formation du mélange extrudé polymère. L'invention concerne également un mécanisme de bain de refroidissement, qui, dans un mode de réalisation, peut également comprendre un tube de refroidissement contenant un milieu de refroidissement forcé dans le tube. L'invention concerne en outre un appareil permettant de préparer des éléments de disque polymère destinés à être utilisés comme matériau d'alimentation polymère pour l'appareil extrusion par micro-onde. L'invention concerne enfin un appareil permettant d'interconnecter et de faire tourner les éléments de disque polymère, la pointe d'extrusion ou l'extrudeuse ou n'importe quelle combinaison de ces éléments afin de créer des caractéristiques d'angularité dans le mélange extrudé polymère.

Title: Electromechanical lock cylinder
Inventor: MUELLER BERNHARD
IPC: E05B47/06
Filed: 2004-06-22
Abstract: The invention relates to an electromechanical lock cylinder, which interacts with evaluating electronics for recognizing an access authorization and comprises a housing that has two opposing cylindrical cavities (12). A lock core, which can be actuated by a key, or a knob shaft (11), which is joined to a knob in a rotationally fixed manner, is rotationally mounted in said cavities. The lock core and/or knob shaft (11) interact with a lock lug (13), which actuates, in particular, a bolt or latch of a door lock.
