| 20120088993 | ELECTROCHEMICAL SENSOR HAVING SYMMETRICALLY DISTRIBUTED ANALYTE SENSITIVE AREAS - The present invention provides an electrochemical sensor that employs multiple electrode areas that are exposed for contact with a body fluid, e.g., when the sensor is inserted subcutaneously into a patient's skin. The exposed electrode areas are arranged symmetrically, such that a symmetrical potential distribution is produced when an AC signal is applied to the sensor. The sensors in accordance with these teachings can advantageously be used with AC signals to determine characteristics of the sensor and thus improve sensor performance. These teachings also provide a biocompatible sensor with multiple reference electrode areas that are exposed for contact with body fluid. | 04-12-2012 |

| 20090326283 | Method and device for the production of alkylene oxide addition products - A method for the production of alkylene oxide addition products comprising (i) charging a stirred reactor with a starting compound capable of adding on or inserting alkylene oxides, introducing at least one alkylene oxide plus a different diluent gas, wherein a portion of said alkylene oxide reacts in a liquid phase with said starting compound, and the remaining alkylene oxide together with said diluent gas forms a gas phase above the liquid phase, (ii) continuously drawing off said liquid phase from the bottom of the reactor via an outlet stub, and recycling to the top of the reactor via an external circulation system, which comprises at least one heat exchanger and at least one Venturi nozzle within said external circulation system, and (iii) metering said gas phase comprising alkylene oxide into said Venturi nozzle via a vacuum line. | 12-31-2009 |
