Inventor: STERNBY JAN
IPC: A61M1/36
Filed: 2002-10-31
Abstract: A method and apparatus for determining a fluid flow rate in a blood access having an upstream position and a downstream position using a blood treatment apparatus including a blood treatment unit having a semi permeable membrane delimiting a first chamber through which blood removed from said blood access passes and a second chamber through which dialysis liquid passes, an arterial line and a venous line, connected to an inlet and an outlet of the first chamber respectively. The method for determining the fluid flow rate involves measurement of the post dialyzer concentration or conductivity before and after a flow reversal. The invention further involves a method for checking the operating configuration of the arterial and venous lines of the blood treatment apparatus.

Abstract: L'invention concerne un ensemble rouleau à peindre présentant un élément rigide et un pinceau facilitant la peinture d'une surface (70) adjacente à une autre surface ne devant pas être peinte simultanément. Cet ensemble comprend un rouleau applicateur (58), un élément rigide (22), un pinceau (28) et un manche (20). Le pinceau (28) est fixé à l'élément rigide (22) et cet élément rigide (22) est relié à un bras (34), monté sur le manche (20) de façon à pouvoir pivoter. Ce bras (34) peut pivoter entre une position de charge de peinture et une position d'application de peinture. En position de charge de peinture, ce bras (34) pivote autour d'un axe parallèle à l'axe longitudinal du rouleau applicateur (58), en s'éloignant du rouleau applicateur (58). On peut ensuite immerger ce rouleau applicateur dans de la peinture sans risquer d'appliquer de la peinture sur l'élément rigide (22). Lorsque cet élément rigide (22) est en position d'application de peinture, sensiblement perpendiculaire et adjacente à l'axe longitudinal du rouleau applicateur (58), ce rouleau applicateur peut être mis en contact avec la surface à peindre (70) et on peut commencer à peindre. Le pinceau (28), de taille, forme et rigidité prédéterminées, est monté sur l'élément rigide (22), de sorte que les poils, ou toute autre section d'application de peinture de ce pinceau (28), se situent à une angle non orthogonal par rapport à la surface à peindre (70) et s'étendent vers un bord de la surface à peindre (72), mais pas sur la surface adjacente (74). Lorsque cet ensemble est utilisé, le rouleau applicateur (58) applique de la peinture jusqu'à une courte distance par rapport au bord de la surface à peindre (72) puis le pinceau (28) retire un peu de peinture de la surface (70) et l'applique sur le bord (72).

Abstract: La présente invention concerne des dispositifs et des procédés de manipulation d'analytes polarisables par diélectrophorèse afin de permettre la détection améliorée d'analytes cibles. Des dispositifs microfluidiques sont conçus de telle sorte que l'application d'une tension entre des électrodes génératrices de champs entraîne la génération d'un champ électrique asymétrique dans le dispositif. Certains modes de réalisation de l'invention font appel à un étranglement physique et à un matériau électroconducteur flottant ou à une combinaison des deux techniques afin de générer un champ asymétrique. L'utilisation de la diélectrophorèse permet de concentrer ou de séparer les analytes cibles des analytes contaminants et de les transporter vers un module de détection.

Abstract: In accordance with one embodiment of the present invention, the ion-beam apparatus takes the form of an end-Hall ion source in which the detachable anode module incorporates the outer pole piece and includes an enclosure around the anode that both minimizes the loss of working gas and confines sputter contamination to the interior of this enclosure. This detachable anode module is substantially smaller than the entire end-Hall ion source, weighs substantially less, and can be duplicated for significantly less cost than the duplication of the entire ion source. In general, the components of the magnetic circuit determine the overall size, weight, and much of the cost of a gridless ion source.  The reduced size, weight, and cost of the detachable anode module compared to the entire ion source is due to most of the magnetic circuit being excluded from the detachable module.

Abstract: L'invention concerne un amplificateur de détection (15) qui peut être configuré pour fonctionner selon deux modes pour commander une excursion de tension au niveau de la sortie (40) de l'amplificateur. Ledit amplificateur de détection comporte deux chemins de réaction (45 à 35) comprenant un premier chemin de réaction (P101, N101, N133) comportant un transistor (N133) présentant un temps de réponse réduit pour permettre au circuit de fonctionner avec la plus grande rapidité possible, ainsi qu'un second chemin de réaction (P121, P102, N102, N121, N132, N131) pour la commande de l'excursion de tension. Dans le premier mode de fonctionnement, ou mode turbo , les deux chemins de réaction fonctionnent (AMPLIFICATION = ELEVEE) pour fournir une marge supérieure de commande d'excursion, et donc une vitesse de détection supérieure. Dans le second mode de fonctionnement, ou mode non turbo , seul le premier chemin de réaction fonctionne (AMPLIFICATION = FAIBLE), ce qui permet d'accroître la stabilité et de réduire la consommation d'énergie.

Abstract: This invention can be used in the food industry. The invention relates in general to multi-purpose closures used for bottling and storing expensive high-quality drinks. The technical result of the proposed invention is a more reliable closing of bottles, providing the necessary tightness, and making refilling the bottle with low-quality drinks less possible. The closure comprises a discharge sleeve with outer and inner pipes at its inlet end, a collar with an external thread at its outlet end, an inner hood with splines on its side exterior surface and a pouring tube at its outlet end, a removable check valve installed on the exterior side surface of the inner pipe, said check valve having sealing lips on its exterior surface and a flange on its outlet end, said flange being located between the inner and the outer pipes. The outer pipe has longitudinal ribs on its interior surface. The collar of the discharge sleeve has a plug installed therein, said plug being supported by raking props and used to shut off the pouring tube. The inner hood is threadedly engaged on the collar of the discharge sleeve thereby to allow its axial movement resulting from rotation. The outer hood has a tamper-indicating means at its outlet end, splines on its interior side surface thereby to engage splines on the inner hood, and transverse projections to interact with the inlet end of the outer pipe of the discharge sleeve. The discharge sleeve has windows evenly spaced around its periphery. The mating surfaces of the pouring tube and the plug are tapered.  The tamper-indicating means at the outlet end of the outer hood is made as a break-away member fixed on the end surface by means of at least three break-away strips, which are spaced evenly around the periphery of the interior surface of the end of the outer hood, or by means of a solid annular break-away strap located at the interior surface of the end of the outer hood. The ball of the valve is made of e.g. glass, crystal glass, marble. A sealing gasket is placed between the outer pipe and the inner pipe of the discharge sleeve. The longitudinal ribs on the interior surface of the outer pipe are separated or arranged in groups to interact with the mating surface of the bottleneck collar.

Title: Process for producing modified epoxy resin
Inventor: UENO MASAKUNI
IPC: C08L63/00
Filed: 2004-05-27
Abstract: A process for easily and efficiently producing an epoxy resin composition comprising an epoxy resin and core/shell type rubber particles (particles of a rubbery polymer) dispersed therein. The epoxy resin composition produced has a reduced impurity content and the rubbery-polymer particles in the epoxy resin are in a satisfactorily dispersed state. An aqueous latex of rubbery-polymer particles (B) is brought into contact with an organic medium (C) having partial solubility in water and then with an organic medium (D) having lower partial solubility in water than the organic medium (C) to substantially separate the water. Thus, a dispersion (F) comprising an organic medium and the rubbery-polymer particles dispersed therein is taken out. The dispersion (F) is mixed with an epoxy resin (A), and volatile matters are distilled off to thereby obtain an epoxy resin composition in which the rubbery-polymer particles are satisfactorily dispersed in the epoxy resin and which has a reduced impurity content.
