Inventor: LEADER MATTHEW J
IPC: G01N27/404
Filed: 1991-12-09
Abstract: The electrode (19) of the present invention has metallic surface within a laser produced opening (18) where the metallic surface extends into an electronic metallic conductive pathway (12b) and the pathway is covered for electric insulation by an encapsulant layer (16). The encapsulant layer around the metallic surface has the opening to allow the exposure of the metallic surface from the encapsulant layer. The metallic pathway and encapsulant are resident on a substrate (10), and are produced from layered circuitry. The electrochemical cell has the aforementioned electrode juxtaposed to another electrode (14). This electrode is part of the patterned metallic layer that is produced by layered circuitry. The electrode extends into an electronic metallic conductive pathway (12a) that is spaced apart and electronically insulated from the other pathway. The insulation can be supplied by a covering of encapsulant material that covers the pathway except does not cover the second electrode. The encapsulant would not cover the second electrode by virtue of its removal by laser and/or masking during production of the layered circuitry. Both of the electrodes are covered with an oxygen permeable fluid electrolyte (32) that provides ionic contact between the two electrodes. The electrodes and electrolyte are covered with one or more oxygen permeable membranes (30,34), and these along with the metallic conductive pathways are resident on a substrate. The cell is useful in detecting oxygen in fluids when a negative potential is applied to the laser-produced electrode relative to the other electrode through the pathways that are in contact with leads (24,26) for external electrical contact from the substrate.

Abstract: Disclosed is a method of obtaining an acid addition salt, crystalline compound of the formula: 
 
 
 
        H-MetO₂-Glu-His-Phe-D-Lys-Phe-OH. 
 
 
 
The resulting crystalline hexapeptide salt has better intranasal absorption characteristics in comparison to amorphous hexapeptide. The method includes: a) dissolving relatively pure hexapeptide into an aqueous acidic solvent; b) concentrating the resulting solution under reduced pressure at an elevated temperature; c) measuring the pH of the concentrated solution, and if the pH is between 4.5 and 4.8, then d) maintaining the temperature of the concentrated solution between 6 and 20 o  C, if the measured pH of the concentrated solution is lower than 4.5, then adding water to the solution and repeating step b) until a pH of 4.5 to 4.8 is attained; and then e) removing the crystals from the concentrated solution by filtration at lower temperatures. Previously obtained "seed" crystals comprising the acid addition salt of the hexapeptide may be used to hasten the process. Once obtained, the crystalline compound may be used in the treatment or prevention of neuropathies or dementia.

Abstract: A method of and apparatus for removing a thrombus deposit from the cardiovascular system of a patient without the need to surgically access the location of the thrombus deposit via a cut-down or other surgical procedure. A catheter (12) is inserted percutaneously into the patient at a convenient location either directly or over a previously positioned guide wire. The distal end of the catheter is advanced under fluoroscopy to the site of the thrombus deposit. A balloon (14) is inflated to stabilize the position of the distal end of the catheter within the center of the vessel lumen. A flexible metal tube (118) conveys an extremely high pressure stream of sterile saline solution to at least one jet at the distal end of the catheter. At least one jet positions the thrombus deposit for emulsification by at least one other jet. By directing the jets toward the orifice of the large evacuation lumen of the catheter, a stagnation pressure is induced which propels the emulsion proximally for disposal. The rate of proximal flow of effluent is metered to correspond with the distal flow of saline solution to ensure minimal local impact on the vasculature at the site of the thrombus deposit.

Abstract: Un dispositif d'aération de réservoir pour véhicule à moteur comporte un réservoir de carburant (KT) pourvu d'un capteur d'hydrocarbure (HCS), un filtre d'adsorption (AT) et une soupape d'aération (TEV) du réservoir. Si le capteur d'hydrocarbure indique que la concentration de vapeur de carburant se trouve au-dessus de la limite prescrite, on peut s'attendre, au moment où la soupape d'aération de réservoir est ouverte, à ce qu'une correction lambda donnant un mélange plus pauvre soit nécessaire. Si aucune correction n'est constatée, cela indique que soit le dispositif n'est pas étanche ou que la soupape d'aération du réservoir n'est pas correctement ouverte. Pour pouvoir exécuter le procédé de contrôle, le dispositif ne doit être équipé que d'un capteur complémentaire, c'est-à-dire le capteur d'hydrocarbure placé dans le réservoir. Ce dispositif est donc plus simple que ceux que l'on connaît déjà et il permet cependant de contrôler de façon fiable son aptitude au fonctionnement.

Abstract: Un catalyseur (16), dans lequel on a remplacé une certaine quantité d'un matériau relativement cher tel que le platine, par une quantité supérieure d'un matériau relativement économique tel que le palladium. De cette façon, les économies réalisées par "l'adaptation" d'un ensemble permettent l'acquisition d'une quantité plus importante d'un matériau moins cher. Bien que ce matériau moins cher soit généralement moins efficace intrinsèquement que le matériau coûteux, on peut en utiliser une quantité supplémentaire suffisante pour compenser avantageusement ce manque d'efficacité. De ce fait, on peut fabriquer un ensemble catalytique possédant une efficacité catalytique élevée, un coût réduit en matériau, une faible perte métallique ainsi qu'une longue durée de vie.
