Patent CA-2217772-C (CA)
Title: Ensemble en resine synthetique comprenant une ou des membranes pincees
Inventor: CHIBA NORIAKI
IPC: F02M37/12
Filed: 1997-02-13
Granted: 2005-04-05
Abstract: Une membrane flexible (62) est pourvue, au niveau du bord périphérique externe, d'une nervure de renforcement annulaire (63) de type joint torique d'étanchéité, et des rainures (70, 71), dans lesquelles la nervure de renforcement annulaire (63) est maintenue par compression, sont formées entre des premier et second éléments (60, 61) en résine synthétique qui retiennent la membrane. Une partie, se trouvant sur le côté extérieur des rainures (70, 71) retenant la nervure annulaire de renforcement (63) et comportant les premier et second éléments (60, 61) en résine synthétique en contact l'un avec l'autre, est fondue au moyen d'un appareil de fusion ultrasonique (65). Un écartement (76) est créé entre le premier élément (60) en résine synthétique et l'appareil de fusion ultrasonique (65), et l'opération de fusion est mise en route afin de combler l'écartement (76) et de mettre en contact le premier élément (60) en résine synthétique et l'appareil de fusion ultrasonique (65). La progression de l'opération de fusion est bloquée par la compressibilité de la nervure de renforcement annulaire (63) restant constante. Selon une autre réalisation, un espaceur métallique (77) est placé entre les premier et second éléments (60, 61) en résine synthétique, et des vides (78) sont formés dans un (61) des éléments en résine synthétique et l'espaceur métallique (77) avant de procéder à l'étape de soudage. Au fur et à mesure de la progression de la fusion, les vides (78) sont éliminés. Ceci empêche la progression de la fusion et fixe la compressibilité de la nervure de renforcement annulaire (63) à un niveau constant.

Abstract: An end-of service indicator for use with a respirator cartridge, the end-of service indicator hvaing an optical fiber having two opposite extremities, one of the extremities being connected to a light source, the other of the extremities being connected to a detector which measures the intensity of light transmitted by the fiber. An alarm is connected to the detector and is triggered when the intensity of light measured by the detector is below a predetermined level. An important aspect of the end-of service indicator is that at least a portion of the optical fiber is porous. In use, the end-of service indicator is placed inside a respirator cartridge having a gas/vapor sorbent, so that when the respirator cartridge is used in a toxic environment, the gas/vapor sorbent gradually becomes saturated, thereby lowering the transmission properties of the optical fiber.

Abstract: Mélanges de boissons nutritives parfumées au chocolat et autres mélanges comestibles enrichis par des sources de fer à haut degré de biodisponibilité, comme le fumarate de fer et le sulfate de fer, sans pour autant présenter de coloration grisâtre au moment de la reconstitution de la boisson avec de l'eau ou du lait ou même lorsque l'eau ou le lait a été porté à ébullition. Ce problème de coloration grisâtre a pu être résolu en ajoutant des acides comestibles comme de l'acide citrique ou de l'acide malique comme agents tampons afin que le pH de la boisson chocolatée ainsi reconstitué se situe aux environs de 6,5 ou moins. Un autre avantage de l'adjonction d'acides/sels tampons comestibles tient au fait que ces acides ou ces sels tendent à stabiliser l'arôme du chocolat dans la boisson reconstituée. L'inclusion d'acides/sels tampons comestibles dans la boisson parfumée au chocolat est prête à servir ainsi enrichie par des sources de fer à haute biodisponibilité prévient également l'apparition de cette coloration grisâtre.

Abstract: La présente invention concerne un système de télécommunications AMDC, qui bloque l'émission de données entre noeuds communiquants jusqu'à ce que le débit binaire de transmission requis par les noeuds communiquants ait été complètement établi dans l'ensemble du système, et qui supprime sélectivement (314) la tonalité de confirmation que les noeuds destinataires envoient aux noeuds origines. L'émission des données vocales, télécopie ou informatiques est bloquée jusqu'à ce que la voie de transmission ait atteint le débit binaire désiré. Cela permet au système de transporter avec fiabilité des données codées selon plusieurs débits binaires dans un système de télécommunications dont la synchronisation est susceptible de ne pas être assez précise.

Abstract: Gas generating compositions and methods for their use are provided. Metal complexes are used as gas generating compositions. These complexes are comprised of a metal cation template, a neutral ligand containing hydrogen and nitrogen, sufficient oxidizing anion to balance the charge of the complex, and at least one cool burning organic nitrogen-containing compound. The complexes are formulated such that when the complex combusts, nitrogen gas and water vapor is produced.  Specific examples of such complexes include metal nitrite amine, metal nitrate amine, and metal perchlorate amine complexes, as well as hydrazine complexes. A binder and co-oxidizer can be combined with the metal complexes to improve crush strength of the gas generating compositions and to permit efficient combustion of the binder. Such gas generating compositions are adaptable for use in gas generating devices such as automobile air bags.

Abstract: A pen computer includes an elongated pen barrel having a writing end provided with a rotatable ball bearing that serves as a ballpoint writing tip. The pen barrel is adapted to be held on one hand for forming characters on a writing surface via the ball bearing.      First and second encoding assemblies are mounted on the writing end of the pen barrel, encode movement of the ball bearing along X and Y directions, and generate X-axis and Y-axis drive signals corresponding to encoded movement of the ball bearing along the X and Y directions. A processor is configured to operate as a character recognition unit. The processor is disposed in the pen barrel, and is connected electrically to the first and second encoding assemblies to receive the X-axis and Y-axis drive signals therefrom. The processor identifies the characters formed on the writing surface via the ball bearing from the X-axis and Y-axis drive signals, and generates computer codes that are assigned to the characters identified thereby.

Title: Conical stacked-disk impeller for viscous liquids
Inventor: MARKOVITCH PETER T
IPC: F04D5/00
Filed: 2000-10-17
Granted: 2005-02-08
Abstract: One or more improved pump impellers are provided and are rotationally supported in a pump having one or more stages. The improved impeller comprises a fluid induction core of flow passages spiraling axially about the impellers rotational axis and a stack of circular disks extending radially and concentrically from the induction core. The stack of disks is preferably a frusto-conical stack with the disks at the downstream end of the impeller having a lesser radial extent than do the upstream disks so that incrementally less fluid issues from each successive radial flow passage between adjacent disks thereby reducing head loss in the issuing viscous fluid flow and increasing pumping efficiency. Increased pump efficiency permits one to provide a conical pump housing profile about each impeller which corresponds with the conical stack, thereby diminishing the fluid flow area and increasing the discharge pressure and flow capacity of each pumping stage.
