20100187319 | RANKINE CYCLE POWER PLANT HEAT SOURCE CONTROL - Provision is made in an organic rankine cycle power plant for modulating the flow of hot gases from a thermal source to the evaporator. The modulation device may be a blower on the downstream side of the evaporator or a valve on the upstream side thereof. The modulation device is controlled by generation of a digital signal to enable or disenable the modulation device and an analog signal for adjusting the position of the modulation device. | 07-29-2010 |
20100219987 | ROTOR SYSTEM HEALTH MONITORING USING SHAFT LOAD MEASUREMENTS AND VIRTUAL MONITORING OF LOADS - A method of real-time rotor fault detection includes measuring a set of loads to obtain measured signals and virtually monitoring the set of loads to obtain estimated signals. The estimated signals are subtracted from the measured signals to obtain residuals and the residuals are compared to a categorical model. A categorical output representative of a rotor fault is identified within the categorical model. | 09-02-2010 |

20120021306 | ACID FUEL CELL CONDENSING HEAT EXCHANGER - A heat exchanger for a fuel cell includes first and second heat exchanger portions that provide a fluid flow passage. The second heat exchanger portion is arranged downstream from the first heat exchanger portion. The first and second heat exchanger portions include a coolant flow passage, which is provided by tubes in one example. The first and second heat exchanger portions are configured to transfer heat between the fluid flow and coolant flow passages. The first heat exchanger portion is configured to provide a first heat transfer rate capacity. The second heat exchanger portion includes a second heat transfer rate capacity that is greater than the first heat transfer rate capacity. In one example, the first heat exchanger portion includes tubes and does not include any fins, and the second heat exchanger includes spaced apart fins supporting the tubes. | 01-26-2012 |
