| 20080257568 | Fire-Extinguishing System in an Air Filter System and Method Therefor - Fire-extinguishing system in an air filter system has an inlet chamber and an outlet chamber with a filter wall therebetween. The system includes a first and second sensor, a first and second fire extinguisher, and a control unit, the first sensor and the first extinguisher being disposed in the inlet chamber, the second extinguisher in an outlet chamber and the second sensor being disposed in an outlet of the outlet chamber. The control unit is connected to the first and second sensors, and to the first and second extinguishers. The control unit records a first and second fire-detection signal in the inlet chamber and the outlet, respectively; compares the first and second signals to an associated threshold value for fire; determines at which location within the inlet and outlet chamber the fire is burning, depending on the comparison; selects which of the first and at least one second extinguisher is located near the determined position, and activates one or more selected extinguishers. | 10-23-2008 |
| 20090194299 | Flexible Hose Supply Line For Appliance Fire Suppression System - A fire suppression system for an appliance is provided. The fire suppression system includes a fire suppression storage container for storing a fire suppression agent, a detection system that interacts with a release assembly, a release assembly in communication with the fire suppression storage container for controlling the release of the fire suppression agent from the fire suppression storage container, a nozzle in a fixed position relative to the appliance, and a fire suppression agent conduit from the fire suppression storage container to the nozzle. The fire suppression agent conduit acts as a conduit for the fire suppression agent from the fire suppression storage container to the nozzle. The fire suppression agent conduit may partly include hard piping and partly include a flexible hose. Since the flexible hose is bendable, it enables movement of the appliance so that the area around the appliance may be cleaned. Further, swivel connectors may connect the flexible hose with the hard piping, thereby reducing the possibility that the flexible hose kinks during movement of the appliance. In addition, a restraining cable may be connected between the appliance and a wall, thereby limiting the appliance movement and reducing the possibility of damage to the flexible hose. | 08-06-2009 |
| 20090294141 | FIRE EXTINGUISHING SYSTEMS AND METHODS - A fire extinguishing system for suppressing fires on cook stoves, fryers or other heating or heated devices with fire suppressant dispensed through nozzles is powered by batteries which provide current for both a detection circuit including a pair of heat sensors and control circuitry and current for a gas or electric house current shut-off. The appliance shut-off device is operated by the standard hardwired interconnect cable that provides a signal between the control board and shutoff device or by an optional sonic receiver assembly that is acoustically tuned to detect an audible alarm emitted by a signal from the main control board. Preferably, the heat sensors are diodes, but in alternative embodiments may be thermistors or active temperature sensors. Mounting of heat sensors and nozzles are facilitated by tees and 90 degree elbows. While the standard interconnect cable is usually used between the control circuitry and shutoff device, a wireless link, such as the sonic receiver assembly, may also be used with the shutoff device. | 12-03-2009 |
| 20100000747 | Cookstove fire extinguishing system - An improved fire protection system that is of fail safe design for kitchen stoves and other applications utilizing gas for generating heat and in which a fire condition such as a skillet of grease becomes ignited. Said system is activated thermally to release a quantity of fire suppressant material onto the top of the stove quenching the fire while simultaneously cutting off the cooking gas. The system utilizes a reservoir containing the fire suppressant under pressure with a hose or pipe connected to one or more thermally activated spray heads. A second hose or pipe is connected to a pneumatically operated gas cut off valve. The activation of the thermally activated spray head or heads exhausts the pneumatic pressure of the reservoir thereby causing the gas cut off valve to close against the cooking gas. | 01-07-2010 |
| 20100139935 | Cook stove extinguishing system - An improved fire protection system that is of failsafe design for kitchen stoves with or without a range hood and other applications utilizing electrical power for generating heat and in which a fire condition such as a skillet of grease becomes ignited. Said system is activated thermally to release a quantity of fire suppressant material while simultaneously cutting off the electrical power. The system utilizes a reservoir containing the fire suppressant under pressure with a hose or pipe connected to one or a plurality of thermally activated nozzles. A second hose or pipe is connected to a pneumatically operated electrical interruption device. | 06-10-2010 |
| 20110042110 | Flame Arresting Grease Filter - The invention relates to a device for arresting flames in a gas flow, for example in a kitchen hood, the device includes at least two substantially parallel spaced apart fire proof sheets, wherein the sheets are provided with perforated zones, wherein at least a channel is formed by a perforated zone of the sheet upstream of the gas flow, the space between the at least two sheets and a perforated zone of the sheet downstream of the gas flow, wherein the channel includes a section which has a reverse direction relative to the gas flow. | 02-24-2011 |
| 20110088919 | FIRE-EXTINGUISHING DEVICE FOR AN OIL STOVE - The present invention relates to a device for rapidly extinguishing a fixed-wick oil stove by closing off an oil-supply tube when the oil stove is overturned or an earthquake occurs. More specifically, it relates to a device of this type which is formed using just a construction having no need for an electrical power source, which reduces costs, which entails no risk of breakdown, and which after the oil stove has been extinguished can straightforwardly be restored to the state prior to operation. The present invention is a fixed-wick oil burner which comprises: a hexahedral housing ( | 04-21-2011 |
| 20110308825 | Automatic fire extinguishing equipment of a fume hood - Automatic fire extinguishing equipment of a fume hood includes a cabinet having a workbench, a vent pipe, and ventilation equipment. In front of the cabinet is a window panel. Top rim of the workbench has first and second detection elements, and automatic fire extinguishing equipment mechanisms. The ventilation equipment contains a fire damper. When fire occurs at the workbench from experiments, the first detection element detects a fire signal first to issue alarming sound (or alerting flash) promptly, the ventilation equipment shutdowns, with the fire damper closed for closing the vent pipe. When the second detection element detects a smoke or high temperature signal, the window panel is closed, with the automatic fire extinguishing equipment mechanisms activated automatically to terminate flame, thereby preventing thick smoke or flame from channeling into the vent pipe to spread the fire, and preventing the fume hood from starting a cascade of fire. | 12-22-2011 |
| 20120018179 | FIRE SUPPRESION - The present invention relates to a fire suppression apparatus | 01-26-2012 |
