Abstract: Un système diagnostique, doté d'un dispositif de contrôle, comprend un dispositif permettant de détecter des lectures de réflectance multiples effectuées dans un ensemble de zones individuelles, un dispositif permettant d'introduire une cartouche d'analyse dans le dispositif de contrôle en un point et selon une orientation fixes par rapport à cet ensemble, ainsi qu'un dispositif permettant de déterminer et d'afficher des résultats d'analyse provenant des lectures de réflectance. Il comprend aussi une cartouche d'analyse munie d'un boîtier étanche aux liquides, d'un site d'application d'échantillon placé dans ce boîtier mais restant hors du dispositif de contrôle lorsque la cartouche y est insérée par le dispositif d'introduction, d'un ou plusieurs sites de lecture de réflectance placés dans le logement et entrant en contact avec une ou plusieurs zones de l'ensemble, d'un conduit capillaire placé dans le boîtier et menant du site d'application d'échantillon à chacun des sites de lecture de réflectance, ainsi que d'une matrice de réflectance placée dans l'un au moins des sites de lecture de réflectance. Dans certaines variantes de l'invention, on trouve des éléments de contrôle optimisant la précision de mesure en contrôlant le moment effectif où les échantillons parviennent aux sites de lecture de réflectance et en évacuant les échantillons surabondants hors des zones critiques de la cartouche. Un élément de contrôle équilibre les capacités en liquide du site d'application, du conduit capillaire acheminant les échantillons au site de lecture de réflectance, et des matrices poreuses sur lesquelles interviendront ces lectures de réflectance, de manière que ces échantillons surabondants ne puissent entrer dans la cartouche, alors que les volumes d'échantillons inférieurs au minimum nécessaire pour un fonctionnement précis ne peuvent parvenir à la matrice, ce qui évite ainsi toute lecture erronée.

Title: Current sensor for medical devices including connector cables
Inventor: THOMPSON RICHARD K
IPC: A61B19/00
Filed: 1993-12-16
Granted: 1999-01-26
Abstract: A current sensing device enables sensing the current being delivered from a source to a load at a medical implement connected to the distal end of a primary conductor connected between the source and the load in situations wherein distributed capacitance between the primary conductor and a return path to the source prevents a measurement of current at the source end of the primary conductor from being an accurate measurement of the delivered current.  The current sensing device comprises a reference conductor which is located beside and twisted together with the primary conductor along the length thereof but which terminates short of, and is not connected to, the medical implement load, and a subtractor for subtracting the current flowing through the reference conductor from the total load current flowing to the medical implement so as to offset the effect of the distributed capacitance and to thereby produce a current measurement corresponding to the delivered current.  The subtractor can comprise a current transformer through which the conductors extend in opposing relation.  An integrity detector monitors whether the reference conductor is intact.

Abstract: C4 hydrocarbons are separated from a gaseous mixture containing the same and lower hydrocarbons and hydrogen, by cooling such a gaseous mixture (45) to a temperature between -60°F and +32°F until a portion of the C4 hydrocarbons is condensed. The mixture of gas and liquid C4 hydrocarbons thus produced is phase separated in a first phase separation (53), and the liquid from this first phase separation is withdrawn as C4 hydrocarbons product (69). Gas from the first phase separation (53) is further cooled(47) until substantially all of the remaining C4 hydrocarbons are condensed but not the hydrogen. The latter material is subjected to a second phase separation (75), and liquid from the second phase separation (77) is withdrawn as liquid C4 hydrocarbons product (69). Vapor from the second phase separation (75) is withdrawn and expanded isentropically in a first expansion engine (81) to produce a mixture of liquid and vapor, which is subjected to a third phase separation (85), and liquid from the third phase separation (85) is withdrawn as liquid C4 hydrocarbons product (69). A portion of vapor separated in the third phase separation (85) is expanded isentropically in a second expansion engine (137), and refrigeration from vapor from the second expansion engine (137) is recovered by indirect heat exchange (47) with the first-mentioned mixture (45). Gas separated in the third separation (85) is cooled to produce a mixture of gas and liquid, which is phase separated (103 or 123). Gas from the latter phase separation is expanded isentropically in the second expansion engine (137), and refrigeration from material from second expansion engine (137) is also recovered by indirect heat exchange (99) with gas separated in the third phase separation (85).

Abstract: A solid state process for the bulk conversion of a dense polycrystalline ceramic body to a single crystal body has been accomplished by heating the polycrystalline material to a temperature above one-half of the melting temperature of the material but below the melting point of the material. As the process is a solid state process, no melting of the ceramic body is necessary to convert it to a single crystal. The process has been used to convert a dense polycrystalline alumina body (PCA) containing less than 100 wppm of magnesia to sapphire (single crystal alumina) by heating the PCA to temperatures above 1100°C but below 2050°C, the melting point of alumina.

Abstract: Un amortisseur tubulaire en élastomère (11) comporte un axe central (12) à l'intérieur d'un logement (13) et est entouré par un élément en élastomère (14). Une déformation uniforme est produite à travers l'élastomère situé entre l'axe central et le logement soit en réduisant progressivement la longueur de l'élastomère d'une surface d'adhérence intérieure  (15) à une surface d'adhérence extérieure, de sorte que le produit du rayon par la longueur correspondant à chaque point le long de l'élastomère soit égal, soit en fournissant une première couche d'élastomère (28) adjacente à l'axe (26) ayant une capacité d'amortissement plus faible aux contraintes de fatigue élevées, une deuxième couche élastomère (29) adjacente au logement (27) ayant une capacité d'amortissement plus élevée aux faibles contraintes et une couche d'élastomère intermédiaire  (30) de déformation et d'amortissement modérés entre les deux premières de façon à atteindre une déformation uniforme entre le rayon intérieur et le rayon extérieur de l'élément en élastomère. Avec une déformation uniforme entre le rayon intérieur et le rayon extérieur de l'amortisseur en élastomère tubulaire, on évite les températures élevées produites par des contraintes élevées localisées qui sont préjudiciables au rendement de l'amortisseur. Des passages axiaux de refroidissement dans l'élément en élastomère  sont fournis en option pour dissiper la chaleur et permettre le fonctionnement dans les limites des paramètres de conception, ce qui prolonge la durée de vie de l'amortisseur tubulaire en élastomère.

Abstract: To thicken retentate residues using ultra- or microfiltration to clarify fruit juices, apparatuses which have membrane modules (1, 2) are used in the cross-flow process with a retentate circuit. It is proposed that first, the process be carried out with virtually constant retentate overflow velocity at the membranes until there is an increased concentration. Then the transmembrane pressure of membrane modules (1, 2) is kept constant or further increased, and the overflow velocity is reduced, until the desired thickening of the retentate residue is achieved. So that the last reduction step can be carried out, speed-governed retentate displacement pumps (8) are employed. To prevent stoppages of the membranes of membrane modules (1, 2), the apparatus is operated with special flow dividers (10) for the retentate, or an individual circulating pump is associated with each group of membrane modules.
