  • Publication number: 20130072492
    Abstract: A compound of Formula (I): or a pharmaceutically acceptable salt thereof, are capable of modulating the body's production of cyclic guanosine monophosphate (“cGMP”) and are generally suitable for the therapy and prophylaxis of diseases which are associated with a disturbed cGMP balance. The invention furthermore relates to processes for preparing compounds of Formula I, or a pharmaceutically acceptable salt thereof, for their use in the therapy and prophylaxis of the abovementioned diseases and for preparing pharmaceuticals for this purpose, and to pharmaceutical preparations which comprise compounds of Formula (I) or a pharmaceutically acceptable salt thereof.

  • Patent number: 6937133
    Abstract: An arbitration process sets the connections to be made between ingress and egress ports of a crossbar switch of a data switching system. A weight parameter is used for each pair of ingress and egress ports. Connection requests are generated indicating ingress ports to be connected to egress ports. A selection is made among conflicting connection requests, to produce a connection proposal for each egress port. Any connection request for which respective weighting parameter is zero is not selected. When one of the connection requests is realised, the weight parameter corresponding to this connection is decreased by one. All the weight parameters for a given egress port are re-set to default values in the case that there are no connection requests for that egress port with non-zero weights.

  • Patent number: 6632257
    Abstract: The addition of a magnesium compound to an ash bearing fuel results in a reduction in the formation of deposits in the turbine and extending the interval between turbine washes when burning the ash bearing fuel in a turbine compared to burning the ash bearing fuel in a turbine without the addition of a magnesium compound. The additive is desirably effective with ash bearing fuel having less than 0.5 ppm vanadium by weight, less than 1 ppm sodium and potassium combined by weight, and greater than about 25 ppm ash by weight or greater than 2 ppm calcium by weight. The additive is blended with the ash bearing fuel to give a mass ratio of magnesium to ash of between about 0.5 to 1 and about 3 to 1, and desirably about 1 to 1 on a mass basis after mixing.

  • Publication number: 20020081231
    Abstract: A fluid analyte measurement system includes an extraction unit having a fluid flow path in intimate contact with an extraction solution flow path. The fluid flow path includes a fluid entry port and a fluid exit port and the extraction solution flow path includes an extraction solution flow entry port and an extraction solution flow exit port. The extraction unit extracts analytes from a fluid flow introduced within the fluid flow path through exposure of the fluid flow to an extraction solution introduced within the extraction solution flow path. A sample head vessel is coupled to the extraction solution flow exit port and at least one probe is coupled to the sample head vessel to generate signals indicative of the characteristics of the fluid flow analytes within the extraction solution flow. For example, this measurement system can be used to determine Na+ level within fuel oil. Circuitry is coupled to the probe(s), which circuitry is configured to measure the signals generated by the probe(s).
