Publication number: 20140202679Abstract: By a feedback arithmetic operation based on a temperature deviation, an input number is set which corresponds to a requested heat quantity generation, which is a controlled object, to a hot water supply apparatus. The temperature deviation is calculated by correcting a deviation of a tapping temperature with respect to a set hot water temperature with use of a Smith compensation temperature calculated by a Smith compensator for predicting a variation in a tapping temperature prior to an elapse of a dead time corresponding to a detection lag of the tapping temperature. The Smith compensator calculates a Smith compensation temperature to be used in the next control cycle based on the input scale number, the present Smith compensation temperature, and a time constant set in accordance with a flow rate of the hot water supply apparatus.Type: ApplicationFiled: January 7, 2014Publication date: July 24, 2014Applicant: NORITZ CORPORATIONInventors: Rena KUSACHI, Yuki MAESHIMA, Hiroki NABESHIMA, Kenichi NAKAYAMA

Publication number: 20140202719Abstract: A system for delivery of a fire extinguishing agent includes an agent tank at least partially filled with a volume of liquid fire extinguishing agent and a supply of pressurizing gas operatively connected to inject pressurizing gas into the volume of liquid agent. A discharge valve is configured to open when the agent tank reaches a desired pressure due to the injection of pressurizing gas therein thereby delivering a flow including fire extinguishing agent with associated dissolved pressurizing gas from the agent tank. The flow of fire extinguishing agent and associated dissolved pressurizing gas is discharged from the agent tank.Type: ApplicationFiled: August 19, 2011Publication date: July 24, 2014Applicant: UTC FIRE & SECURITY CORPORATIONInventor: Joseph Senecal

Publication number: 20140202720Abstract: A method and device for suppressing an electrical fire within an electrical wire carrying conduit. The device is a flexible receptacle containing an admixture of super absorbent polymer and water having substantially superior fire suppression and extinguishing properties that does not provide an electrically conductive environment. The receptacle is drawn though a conduit either before or after wires have been placed in the conduit, and the filled with the admixture. A sleeve may be placed over the receptacle to prevent breaching of the receptacle during installation. Once the receptacle and admixture is positioned within the conduit, should arcing or a buildup of heat occur, the receptacle will rupture and the admixture will cover the specific area. These particular properties and ratios of the admixture will enable electrical fires to be extinguished more rapidly and not flare back up. The admixture further encapsulates noxious and toxic gases associated with electrical fires.Type: ApplicationFiled: October 3, 2013Publication date: July 24, 2014Applicant: GelTech Solutions, Inc.Inventor: Peter Cordani

Publication number: 20140202721Abstract: A smoke-barrier device for securely sealing the spaces beneath and around a door and a fire and smoke retardant door cloth panel will gain two or more hours for a person(s) trapped by a fire in a closed room, even one that has a residential style wood door that is known to burn in about 20 minutes. The combined use of the tested and rated smoke-guard device and the tested and rated fire and smoke retardant panel will prevent fire, smoke, and lethal gases from entering the room through a doorway even after the wooden door burns through.Type: ApplicationFiled: January 20, 2014Publication date: July 24, 2014Applicant: BUTTERFLY SAFETY PRODUCTS LLCInventor: Alan Shaw

Publication number: 20140202722Abstract: A device for protecting a lineman or firefighter from an electrical fire that occurs while working within a manhole. The device dispenses a non-conductive amount of hydrated super absorbent polymer having fire suppression and extinguishing properties without creating an electrically conductive environment. The admixture can cling to walls, ladders, clothing and skin. The admixture is capable of encapsulating noxious gases produced by electrical fires and prevent the release of toxic gases.Type: ApplicationFiled: October 3, 2013Publication date: July 24, 2014Applicant: GelTech Solutions, Inc.Inventor: Peter Cordani

Publication number: 20140202723Abstract: An apparatus for protecting a lineman, firefighter or any other individual using an aerial bucket from a fire. The apparatus dispenses a non-conductive admixture of hydrated super absorbent polymer having fire suppression and extinguishing properties without creating an electrically conductive environment to allow protection from electrical fires. The admixture can cling to clothing and skin with properties that can inhibit injury to an operator lineman when applied in time. A pressurized dispensing system discharges the admixture into the aerial bucket when authorized.Type: ApplicationFiled: December 17, 2013Publication date: July 24, 2014Applicant: GelTech Solutions, Inc.Inventor: Peter Cordani
