Combustion > Timer, Programmer, Retarder Or Condition Responsive Control Timer, Programmer, Retarder Or Condition Responsive ControlTimer, Programmer, Retarder Or Condition Responsive Control 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.03/29/07 - 20070072138 - Atmosphere-control-system design programs and methods Provided are methods for an atmosphere-control-system design using computer software. The methods include receiving a plurality of inputs from a user and retrieving data from a database. Performance parameters are calculated, system components are selected, and a report is generated for the user. Also provided is a computer program product, ... 11/16/06 - 20060257803 - Gas valve controller A gas valve (22) control system (10) for a heater includes a burner (26) and a valve (22) that has a high flow stage and a low flow stage. The valve (22) supplies fuel to the burner (26) in the high flow stage until the burner (26) is ignited. While ... 11/16/06 - 20060257802 - Flame sensing system A low cost flame sensing system having at last one floating point. For instance, the system may have two grounds. There may be a flame sensing rod for detecting a flame which has a model circuit which appears upon the existence of the flame proximate to the sensing rod. The ... 11/16/06 - 20060257801 - Leakage detection and compensation system A flame sensing system having a flame rod, a signal generator, a signal measurement circuit, and a controller, where the frequency and/or amplitude of the excitation signal may be variable. The signal measurement circuit may include a bias circuitry that references the flame signal to a voltage, a capacitor that ... 07/13/06 - 20060154190 - Catalytic combustors keeping contained medium warm in response to hydrostatic valve The medium (9), such as water, of a container (10), such as a fuel cell accumulator, is kept above freezing by a hydrogen/oxygen catalytic combustor (13) fed hydrogen from a source comprising a mechanical thermostatic valve (25) in thermal communication (26) with the container (10) and connected to a hydrogen ... 07/06/06 - 20060147855 - Liquid fuel supply unit for a liquid fuel burner and a liquid fuel burner system A liquid fuel burner system and a liquid fuel supply unit (101) for the liquid fuel burner (106) of the system are disclosed. The supply unit (101) comprises a liquid fuel feed pump (102), a compressor (104 and preferably also a motor (30) mounted on a common drive shaft (3). ... 05/18/06 - 20060105279 - Feedback control for modulating gas burner A modulating gas burner control system using closed loop feedback from a flame rod which provides a signal that varies with gas pressure and which provides combustion air fan control to accurately control the heat from the system without use of expensive control valves. ... 12/01/05 - 20050266362 - Variable input radiant heater A variable demand radiant heating system applies variable burner control technology to singular or mulit-burner radiant heating systems. A radiant heater consists of a burner connected to an elongated heat exchanger tube. The combustion air is supplied to the burner via blower or draft inducer. Fuel is supplied to the ... 11/17/05 - 20050255417 - Draft inducer having a backward curved impeller A draft inducer is disclosed. The draft inducer includes an impeller having one or more backward curved blades. The impeller is coupled to a motor which is preferably a DC motor. The DC motor resides at the center of the impeller and is housed within the impeller structure. The draft ... 10/20/05 - 20050233272 - Control unit for controlling the delivery of a combustible gas in valve units, particularly for water heating apparatuses, and valve unit including said unit A control unit is provided for controlling the delivery of a combustible gas in a valve unit of the type having a valve for shutting off the gas which is subject to the operational control of a magnetic safety unit with a thermocouple. The control unit includes an electronic circuit ... 10/06/05 - 20050221243 - Enhanced burner performance gas range system and method An enhanced gas range system includes a pressure regulator adapted to regulate a gas flow from a gas feed line. The system also includes a gas fuel boost pump disposed downstream of the pressure regulator and adapted to increase pressure of the gas flow received from the gas feed line. ... 08/11/05 - 20050175944 - Variable low intensity infrared heater A radiant heater including a burner having an inlet for receiving an air and gas mixture and an exhaust for emitting exhaust gases generated by combustion of the air and gas mixture within the burner, an elongated radiant heating tube having an inlet for receiving the exhaust gases emitted by ... 06/30/05 - 20050142508 - Automatic power-off control circuit for essential oil burner An automatic power-off control circuit of essential oil burner is provided for controlling the heating of the essential oil in the essential oil burner, and cutting off power when the essential oil in the essential oil burner is used up. The control circuit includes a power-on switch, an AC/DC transformer, ... 06/09/05 - 20050123873 - Modulating oil fuel delivery system A variable flow rate oil delivery system for delivering oil to an oil combustion system according to the demand of heat needed by the heating appliance to which the combustion system is installed or according to a set function of time and rate. This oil delivery system incorporates a programmable ... ### FreshPatents.com Support |
