Combustion > Timer, Programmer, Retarder Or Condition Responsive Control > With Test Circuit Checking Or Analyzing Flame Sensing Circuit For Malfunction With Test Circuit Checking Or Analyzing Flame Sensing Circuit For MalfunctionWith Test Circuit Checking Or Analyzing Flame Sensing Circuit For Malfunction patent applications listed are from June 2005 to current and include Date, Patent Application Number, Patent Title, Patent Abstract summary and are linked to the corresponding patent application page.01/04/07 - 20070003892 - Single-stage gas valve A combustion assembly includes a single stage gas valve, a burner member having a flame end, a spark generating member, a flame sensing member, and a controller. The spark generating member generates a spark in response to a spark signal and is positioned adjacent to the flame end of the ... 12/21/06 - 20060286495 - Ignition and flame supervision system for open flame gas lights A gas light ignition and flame supervision system for a gas light that comprises a burner tip and a glow coil adapted to be positioned in a operational distance from the burner tip to ignite a flame when heated and to conduct a current through the flame to the tip. ... 12/07/06 - 20060275719 - Warm air furnace baselining and diagnostic enhancements using rewritable non-volatile memory A warm-air furnace is adapted to provide diagnostic enhancements and more robust installation. In an embodiment, sensing equipment aboard the furnace is used to determine a first performance metric during installation of the furnace. That performance metric is then compared with a baseline metric that may have been obtained at ... 11/16/06 - 20060257804 - Dynamic dc biasing and leakage compensation A system for adjusting a bias voltage of a flame sensing system. The system may use pulse width modulation to adjust the bias voltage. The system may have a flame sensing rod that conveys an electrical equivalent circuit of a flame presence to a detector via low pass filter. An ... ### FreshPatents.com Support |
