  • Patent number: 9926209
    Abstract: A method for on-site aerial dissemination of Oxidatively Converted particles of contamination with substantial atmospheric disposal, commonly known as aerosolization, of the water component of all untreated or partially treated leachates and all untreated or partially treated wastewaters. These leachates and wastewaters (defined as water containing 2 or more detectable and known contaminants) are collected on site and the defined leachate or defined wastewater, having multiple defined and known contaminating suspended and perhaps precipitated solids therein, and aerially disseminating or aerially oxidizing or commonly known aerosolizing said contaminants over a chosen contaminant collections area (defined as 1-300 meters from the nozzles) and disposing of the water component of the leachate or wastewater through atmospheric disposal and lastly evaporation on the site of the leachate or wastewaters' generation.

  • Patent number: 9726405
    Abstract: An ejector includes a first nozzle, a second nozzle, an atomization mechanism, and a mixer. A working fluid in a liquid phase is supplied to the first nozzle as a drive flow. A working fluid in a gas phase is sucked into the second nozzle. The atomization mechanism is disposed at an end of the first nozzle and atomizes the working fluid in a liquid phase while maintaining the liquid phase. The mixer generates a fluid mixture by mixing the atomized working fluid generated by the atomization mechanism and the working fluid in a gas phase sucked into the second nozzle. The atomization mechanism includes an ejection section that generates a jet of the working fluid in a liquid phase and a collision surface with which the jet from the ejection section collides. The collision surface is inclined with respect to a direction in which the jet flows.

  • Publication number: 20120074242
    Abstract: A snow making spray head that can be adapted to a snow tower is disclosed. The spray head is designed to be rotatable about a vertical axis without having to rotate the tower itself so that the direction of the spray can be adjusted to effectively lay down quality snow onto the trail in an effective pattern under different wind directions.

  • Publication number: 20110285964
    Abstract: A display system for use in winter and other low temperature venues. The system includes a projection screen generation assembly that includes a snow making machine. The snow making machine receives an input flow of a liquid, such as water plus one or more additives to increase opacity and/or reflectivity of the snowflakes. The machine forms snow from the input flow and discharges a volume of flowing snow as a sheet or curtain providing a projection screen. The system includes a high-brightness projector directing light onto the projection screen to provide an image on surfaces of the flowing snow. In some embodiments, the snow making machine includes a nozzle configured such that the flowing snow is output in a substantially planar sheet, e.g., with the use of a diffuser or the like for increasing the laminar nature of the flow and the sheet may be relatively thin.

  • Publication number: 20110174895
    Abstract: A low energy snow making gun having at least one but preferably three operational stages each having at least one pair of small aperture water outlets which are oriented at a divergent angle to generate a respective pair of narrow angled water droplet streams which do not interfere with each other until they have reached a distance from the gun. A second pair of water outlets may be provided on each stage with each pair on each stage oriented at a divergent angle to maintain singularity of the streams over a distance thereby increasing the throwing power of the gun.

  • Patent number: 7965488
    Abstract: An antenna is disclosed to efficiently ionize the atmosphere for the purpose of reducing the aerosol counts, and therefore the number of poluted particles in suspension in the atmosphere, by deposition to ground. The antenna includes peripheral nodes and a central node. Each of the peripheral nodes is connected to adjacent peripheral nodes through peripheral spokes. The peripheral nodes are also connected to the central node through radial spokes. Electric power is applied to the peripheral spokes and the radial spokes causing the antenna to charge the atmosphere through the emission of ions. The antenna minimizes an attenuation factor that reduces ionization efficiency and reduces the land requirements for its installation.

    Abstract: A procedure for moderating the intensity of a hurricane in regions of the seas that are host to the oil and gas industries is described, using the Gulf of Mexico as an example of such a region, and snow-making machines as the instruments for carrying out the procedure. These machines are carried on moving platforms that follow the hurricane and on fixed platforms that are located in the path of the hurricane. In the described procedure snow-making machines are installed on fixed platforms throughout the region, and only those machines that are in the path of an approaching hurricane are turned on, while the snow-making machines on the moving platform(s) are operating continually.

The snow making apparatus also includes a snow accelerator that includes an air compressor, a dehumidifier to remove moisture from the compressed air and a cooling system to cool the compressed dehumidified air. The cooled air is passed through an expansion valve and the modified compressed air is directed through a nozzle positioned to lie near the water nozzles. The modified compressed air has a absolute humidity of about 0.02 g/m3 or less and a temperature of about ?50° Celsius or less. The water mist and modified compressed air are combined, causing the water mist to turn into snow.
