Title: Biocompatible hydrogel bone-like composites
Inventor: SONG JIE
IPC: A61F2/00
Filed: 2003-12-18
Abstract: A template-driven biomineralization process for making three-dimensional bonelike composites having direct and extensive mineral-substrate contact which provides high adhesion strength. The in situ generation of sufficient amounts of surface and interior carboxylates, through an increase in pH, serves as nuclear binding sites for mineral ions to promote high affinity 2-dimensional mineral growth at the substrate-mineral interface. The substrate for the bonelike composites is a hydrogel scaffold comprised of a polymerized base monomer having ydrolyzable ester side chains, crosslinked with a co-monomer and crosslinker. Hydrolysis of the ester containing side chains is preferably mediated by thermo-decomposition of urea.

Patent CA-2522556-A1 (CA)
Title: Rotary drum vacuum filter
Inventor: ROUILLARD PAUL NORMAN
IPC: B01D33/06
Filed: 2005-09-26
Abstract: Prior art washer designs have segmented radial ducts feeding the filter valve which collect the filtrate emerging from the longitudinal ducts. Because these ducts are radial, the volume at the periphery is much greater than at the valve entry which creates undesirable conditions such as a large volume where air can escape from the filtrate forming a pocket which will reduce the effective-ness of the vacuum and promote non-uniformity in filtrate velocity. The present invention incorporates a baffle in the radial duct which reduces the volume at the periphery and maintains a uniform cross-sectional area for the filtrate to reach the valve. This maintains a constant filtrate velocity and prevents the possibility of the formation of an air pocket.

Inventor: FACCIN MARCO
IPC: H02M1/00
Filed: 2006-02-28
Abstract: A circuit arrangement for protecting an electronic converter against overloads includes: - a low impedance path (R7, T1) selectively activatable to prevent ignition of the electronic converter, the low impedance path (R7, T1) including an electronic switch (T1), - a control capacitor (C2) whose charge voltage controls the electronic switch (T1), whereby the electronic switch (T1) is activated to prevent ignition of the electronic converter when the charge voltage of the control capacitor (C2) is above a given threshold, - a first generator (V+) for loading the control capacitor (C2), the first generator (V+) activatable in the presence of a first overload condition of the electronic converter, and - a second generator (V-) for further loading the control capacitor (C2), the second generator (V-) activatable in the presence of a second overload condition of the electronic converter, the second overload condition being heavier than the first overload condition. The first generator (V+) and the second generator (V-) are configured for charging the control capacitor (C2) as long as said electronic converter is ignited. As a consequence, in the case of the second overload condition, the charge voltage (Vc2) of the control capacitor (C2) reaches a higher level: the charge voltage (Vc2) of the control capacitor (C2) thus keeps the electronic switch (T1) activated to prevent ignition of the electronic converter for a longer time than in the case of the first overload condition.

Inventor: SHVARTSBURG ALEXANDRE A
IPC: H01J49/06
Filed: 2004-09-07
Abstract: La présente invention a trait à un procédé et un appareil permettant une sensibilité accrue dans des instruments de spectrométrie de mobilité ionique/spectrométrie de masse qui réduit sensiblement ou élimine la perte d'ions dans les tubes de glissement de spectromètre de mobilité ionique au moyen d'un dispositif pour la transmission d'ions depuis une source d'ions qui permet la transmission d'ions sans retard important vers un entonnoir d'ions électrodynamique en forme de sablier à l'entrée du tube de glissement et/ou un entonnoir d'ions interne à la sortie du tube de glissement. Un entonnoir électrodynamique en forme de sablier est constitué d'au moins un élément d'entrée, d'un élément central, et d'un élément de sortie, dans lequel l'ouverture de l'élément central est inférieur à l'ouverture de l'élément d'entrée et à l'ouverture des éléments de sortie. Des ions générés dans une zone de pression relativement haute par une source d'ions à l'extérieur de l'entonnoir électrodynamique en forme de sablier sont transmis à une zone de pression relativement basse à l'entrée de l'entonnoir en forme de sablier à travers un orifice de limitation de conductance. Des potentiels électriques continu et alternatif sont appliqués aux éléments de l'entonnoir électrodynamique en forme de sablier aspirant ainsi les ions dans et à travers l'entonnoir électrodynamique en forme de sablier permettant ainsi l'introduction de quantités relativement grandes d'ions dans le tube de glissement tout en maintenant la différence de la pression de gaz et de la composition à l'intérieur du tube de glissement par rapport à celles au niveau de l'entrée de l'entonnoir électrodynamique et permettant le maintien d'une pression de gaz positive à la sortie dudit tube de glissement, le cas échéant. Un entonnoir d'ions interne est prévu au sein dudit tube de glissement et est positionné à la sortie dudit tube de glissement. L'avantage procuré par l'entonnoir d'ions interne est que les ions sont dispersés en éloignement de l'ouverture de sortie au sein du tube de glissement, de sorte que ceux qui sont normalement perdus dans des tubes de glissement classiques à toute analyse ou mesure ultérieure, sont plutôt orientés à travers la sortie dudit tube de glissement, accroissant considérablement la quantité d'ions présents dans le tube de glissement.
