摘要： Magnet-thermocouple for the fail-safe safety supply of gas to burners or the like, in particular of fail-safe safety control for domestic cooking devices, comprises: at least one gas burner, which gas burner is connected to a gas supply source by flame-regulating means and by means of a safety valve driven by a flame presence sensor consisting of a thermocouple, said safety valve having an open condition, wherein said supply source supplied said burner, and a closed condition, wherein the gas passage is interrupted and wherein the thermocouple, in the presence of a flame, generates an electrical signal constituting the drive signal for the passage of said safety valve from an open condition to a closed condition, and vice-versa, of said safety valve, whereas a further drive signal generator and power supply of said safety valve is provided, for the temporary and alternative supply of the safety valve during the flame ignition step heating the thermocouple, to the temperature generating the drive signal. According to the invention, the signal generator and power supply comprise power limiters to limit the signal generated and an automatic deactivating unit whenever the power supply is overloaded for a predefined amount of time, the power necessary for the drive signal of the safety valve being greater than the one determined by the limiters.

摘要： A low powered system for providing sufficient current to a fuel control mechanism drive. The system may have a fuel control mechanism pick circuit that has an energy storage mechanism for providing a large amount of current for a short time to the fuel control mechanism drive. A safety switch may be enabled with a special signal to let current flow to the fuel control mechanism drive to operate a corresponding fuel control mechanism for controlling fuel to a pilot light or heating element. The pilot light or heating element may provide heat to a thermoelectric source that generates electrical power from the heat. The electrical power may go to a single DC-to-DC converter and voltage clamp for providing a voltage source to a microcontroller and other circuits of the system. The pick circuit may prevent a harmful reverse flow of current from the storage mechanism to the thermoelectric source.

摘要： Valve assemblies may be configured to perform a valve proving test as part of an operational cycle of a combustion appliance coupled to the valve assembly. The valve assembly may include a valve body having a fluid path, first and second valves situated in the fluid path, first and second valve actuators, and a pressure sensor in fluid communication with an intermediate volume of the fluid path between the first and second valves. A valve controller may monitor a measure related to a pressure in the intermediate volume. The valve controller may then output a signal if the measure related to the pressure in the intermediate volume meets and/or exceeds a threshold value, where the threshold value is determined based on a measure related to an initial pressure in the intermediate volume and a known test duration.

摘要： A heater for a liquid has a combustion chamber, a jacket for the liquid extending about the combustion chamber and a burner head assembly connected to the combustion chamber. The burner head assembly includes a housing having a burner mounted thereon and a hollow interior. A control module and a fan are mounted in the hollow interior, the fan being connected to an electric motor. A compressor and a fuel pump are mounted on the housing and are operatively connected to the electric motor. The control module may include controls for exercising components of the heater prior to combustion, thereby verifying operation of these components. Preferably there is a speed control for the motor, such as a closed loop speed control which regulates motor speed and accordingly output of the heater. Preferably there is a backup system using a lookup table in the event that the closed loop speed control fails. Also preferably there is provision for monitoring flame sensor functionality by providing an indicator light which mirrors operation of the flame sensor. The heater may have a selective soft start for the coolant pump which operates only when required so as to reduce unnecessary chatter on the motor relay. A system is also provided for distinguishing true overcurrent faults from overcurrents arising from voltage changes during starting of the vehicle engine. Reignition algorithms are provided to restart the burner in the event of flame sputters caused, for example, by fuel bubbles, but shut off the heater in the event that the fuel is truly cut off.

摘要： A telemetry system for use in a combustion turbine engine (10) that includes a first sensor (306) in connection with a turbine blade (301) or vane (22). A first telemetry transmitter circuit (312) is affixed to the turbine blade and routes electronic data signals, indicative of a condition of the blade, from the sensor to a rotating data antenna (314) that is affixed to the turbine blade or is on a same substrate as that of the circuit. A stationary data antenna (333) may be affixed to a stationary component (323) proximate and in spaced relation to the rotating data antenna for receiving electronic data signals from the rotating data antenna. A second sensor (335) transmits electronic data signals indicative of the stationary component to a second telemetry circuit (332), which routes the signals to the stationary antenna. The stationary antenna transmits the electronic data signals to a receiver (338).

摘要： A fault detection system and method for a warm air furnace is provided. A sensing circuit connected to an AC power source measures a level of current consumption during several points in the warm air furnace operating sequence. The measured level of current consumption is compared with an expected value. If the measured level exceeds the expected level by a threshold amount, a fault in the warm air furnace may be detected. An indication of at least one warm air furnace component that is most likely to have caused the fault may be provided.
