  • Publication number: 20040048214
    Abstract: A torch lighter includes a fuel nozzle assembly provided for vaporizing the fuel released therefrom to a high-pressured gaseous fuel to emit to the ignition chamber, wherein the vaporizer assembly includes a torch head, which is provided at an emitting end of a nozzle body and supported within a combustion housing, having a root chamber having a size larger than the size of the emitting end of the nozzle body to form a gas stabilizing reservoir to ensure a collective and stable flow of the mixture gas, and two or more elongated nozzle ducts each having an ignition end and a root end extended to a ceiling of the root chamber, wherein a mixture gas ejected from the two ignition ends is ignited in the ignition chamber to form two torches soaring away from the two ignition ends of the two nozzle ducts.

  • Patent number: 6558156
    Abstract: A multi-flame lighter includes a housing, an igniter, a liquid fuel supply, a valve, a vaporizer, a mixing chamber, a nozzle, and a flame chamber. The multi-flame lighter produces clearly visible and forceful flames that are aesthetically pleasing and functional being equivalent to 2 or more of the flames from a conventional tighter as well as being particularly wind resistant. The multiple clearly visible and forceful flames allow a user to easily aim the cigarette or cigar to quickly achieve ignition and easily ignite the cigarette or cigar for ignition and easily ignite the cigarette of cigar with the multiple clearly visible flames.

  • Patent number: 6537062
    Abstract: A windproof lighter includes a gas directing arrangement including a torch nozzle, a gas nozzle, and a gas directing unit including a torch directing conduit and a gas directing conduit for directing a flow of gas toward the torch nozzle and the gas nozzle respectively. A gas detouring unit is movably mounted to the casing to block up the flow of gas passing through the gas directing conduit while the torch directing conduit is remained open. An ignition system installed into the casing for producing sparks directed toward the gas nozzle to ignite the gas emitted from the gas nozzle to provide a visible flame, so as to ignite the gas emitted from the torch nozzle to provide a torch flame. Therefore, the lighter is capable of providing the torch and visible flames at the same time and providing only the torch flame while operating the gas detouring unit.

  • Publication number: 20030022119
    Abstract: A multi-flame lighter which comprises of a housing, an ignition mean, a fuel housing containing combustible liquid fuel, a valve, a connecting tube, an adjustable valve, a vaporizer, a mixing chamber, a nozzle, and a flame chamber. The present invention requires far fewer parts than any existing lighters that can produce multiple flames. The present invention has a simple design and can be manufactured easily at a consistent quality. The manufacturing and parts cost of the present invention is much lower than the existing lighters that can produce multiple flames due to the single valve, connecting tube, single adjustable valve, single vaporizer, single mixing chamber, and single nozzle configuration. The multi-flame lighter produces multiple clearly visible flames that are both aesthetically pleasing and functional. The multiple visible and forceful flames are equivalent to 2 or more of the flames from a conventional lighter and are wind resistant.

  • Publication number: 20020197579
    Abstract: A lighter of multiple torch flames comprises a nozzle and vaporizer assembly that includes a vaporizer, a mixing chamber, and at least two burner nozzle channels generally in V-orientation. The vaporizer has at least one central opening and a filter below the opening, thereby generating a burst of clean vaporized combustible gas to pass through a path toward the burner nozzle channels. The mixing chamber has at least one air inlet where the combustible gas is mixed with fresh air. The nozzle channels have a joint point within a stabilizing chamber of a diameter smaller than that of the path, thereby directing the few combustible gas to diversion channels to form a ring of surrounding flames and most toward the nozzle channels to form at least two forceful and distinct torch flames in straight column shape when being ignited.

  • Patent number: 6080362
    Abstract: A method to disinfect a porous solid medium, such as soil, includes the steps of embedding a plurality of electrodes into the porous solid medium and applying a plurality of alternating current voltage pulses between the electrodes. The voltage pulses have a peak voltage of at least 10 kilovolts and are of an intensity and duration effective to generate a quantity of ozone. The ozone is produced in quantities sufficient to disinfect the porous solid medium.

  • Patent number: 5756054
    Abstract: There is disclosed an ozone generator having enhanced ozone generating capabilities. A cryogenic stream of oxygen is irradiated with a high voltage electron beam that converts a portion of the oxygen into ozone. When the oxygen stream is liquid, conversion rates of up to 33% are achieved. Separation of ozone from oxygen is achieved by exploiting physical properties. In one embodiment, a gaseous mixture is at a temperature between 90 K and 161 K. A condenser coil condenses the ozone to a liquid. The ozone may be directed to a reaction chamber containing a surface increasing medium, such as porous inert beads, to remediate air borne biological and organic contaminants.

  • Patent number: 4663567
    Abstract: An ionizable material is injected in the shape of concentric jet and cylindrical column of gases from a cathode-nozzle toward an anode and subjected to a very short, high voltage pulse of electrical current having sufficient magnitude to create a high magnetic field which implodes the cylindrical column of ionizable material and compresses the central jet of ionizable material to a very dense plasma that is relatively stable longitudinally that can be used as a gain medium for a long wave length X-ray laser.
