  • Patent number: 6106786
    Abstract: A blowing type aroma apparatus, involving no danger of fire and being capable of providing a natural aroma. A body of the aroma apparatus has an opening in its upper surface. A container for containing a liquid aromatic and a cylinder surrounding this container and having open upper and lower ends are located in the opening. An impregnator impregnated with the aromatic is disposed in the container. An axial flow fan is housed beneath the opening within the body and the air flow generated by the axial flow fan passes through the support member and flows into a space between the cylinder and the container. The air becomes a laminar flow and rises in the space between the cylinder and the container. The air flow permits the volatilization of the aromatic contained in the impregnator, whereby the aroma is diffused from the opening at the upper end of the cylinder.

  • Patent number: 6099806
    Abstract: A chemical oxygen or other gas generator which has a container composed of thermally-conductive and gas-impervious material which contains pyrotechnic material, the container being in heat transfer relation with a block of oxygen-producing material for transfer of heat from burning of the pyrotechnic material within the container directly to the block of oxygen-producing material for initiation of decomposition thereof. The container is sealingly attached to the casing so that all of the evolved gases from burning of the pyrotechnic material are segregated from the produced breathable oxygen. The evolved gases are vented from the oxygen generator so as to reduce the ignition chamber pressure and/or allow a greater amount of pyrotechnic material to be burned within the ignition chamber so that a sufficient amount of heat may be generated within the ignition chamber for application to the block of oxygen producing material for initiation of decomposition thereof.

  • Patent number: 6074447
    Abstract: A method for storing and releasing hydrogen fuel includes providing a hydrogenated material in a chamber, introducing a catalyst into the chamber, heating the chamber to about 190.degree. C., separating at least part of the material into dehydrogenated material and hydrogen and releasing the hydrogen from the chamber. A preferred catalyst is a transition metal complex, such as the iridium based complex IrH.sub.4 {2,6C.sub.6 H.sub.3 (CH.sub.2 P(C(CH.sub.3).sub.3).sub.2).sub.2 }. To reverse the process, a hydrogen pressure of about 10 atmospheres or more is provided, and the dehydrogenated material and hydrogen are combined at about or at least 100.degree. C. to regenerate the hydrogenated material. The small, lightweight system for carrying out the present method includes a chamber containing hydrogenated material and a catalyst, and having an outlet with a selectively permeable membrane for releasing hydrogen and containing hydrogenated material and a homogenous catalyst.

  • Patent number: 6071473
    Abstract: A method and apparatus are disclosed for using ultrasonic energy in conjunction with an ultraviolet water sterilization system. An ultrasonic transducer assembly is placed in or around one end of the sterilization chamber for producing the ultrasonic energy. Ultrasonic vibrations are then applied automatically on a regular and intermittent basis to clean the components within the sterilization chamber and disrupt the chemical and physical action which causes scaling due to dissolved minerals and organic materials in the water. The ultrasonic vibrations cause a preventative cleaning action by the streaming and stirring of the water. Actual cleaning action is also created by cavitation and sweeping actions. The sweeping action is accomplished by frequency modulation which, by creating varying hot and cold spots within the sterilization chamber, allows for a uniform cleaning of a quartz sleeve encasing a UV lamp within the sterilization chamber. Ultrasonic vibrations also create a germicidal action.

  • Patent number: 6054097
    Abstract: A method and apparatus for disinfecting material such as a fluid stream, (e.g., water) or various objects (e.g., packaging, fruits, vegetables) using a high temperature expanding plasma emission source (EPES lamp) to generate intense pulses of ultraviolet light primarily in the 200-400 nm range. The EPES lamp is preferably mounted axially in a pipe through which the fluid to be disinfected is flowed or perpendicular to the direction of a fluid flow or an object conveyor. Each pulse is terminated before the resulting plasma within the EPES lamp reaches the inside surface of the EPES lamp wall so that the EPES lamp operates in an expanding plasma emission source mode rather than in a wall stabilized mode. The EPES lamp is operated at a plasma temperature of at least about 15,000.degree. K. and an energy density (Q) of at least about 300.
