  • Publication number: 20110278372
    Abstract: A chemical dispensing apparatus includes a housing that is connectable to a source of water, such as a standard garden house, and an internal space in which is disposed a rotatable container containing a quantity of chemical concentrate to be mixed with the source of water as it flows through the housing and is dispensed from the housing from a sprinkler head or misting nozzle. The flow of water through the housing powers a water turbine which is connected to the rotatable container, such that the container is rotated as water flows through the housing. In an alternative embodiment, the water turbine is replaced with an electric motor. Rotation of the container cause the chemical concentrate to dissolve which is then mixed with the water before it is dispensed through the sprinkler or mister.

  • Patent number: 6591840
    Abstract: A shower of tobacco particles is admitted into the inlet at the top of and descends by gravity and/or under the action of a driven cell wheel in a generally upright duct. The particles are moisturized prior to admission into the duct or due to contact with droplets of water in the inlet, and are thereupon caused to traverse an orbiting shower of steam, water and/or another conditioning medium in an intermediate portion of their path in the duct. Such treatment entails a swelling and thus increases the volume of the particles. The conditioning medium is discharged via orifices radially outwardly from at least one substantially horizontal conduit which is rotated about its axis and can be provided with external pins or analogous mechanical impellers serving to cause the particles of tobacco to orbit about the conduit prior to descending into the range of a dryer at a level below the intermediate portion of the path, e.g., at the outlet of the duct.

    Abstract: An applying means in a discharge means includes a set of electrodes, and the electrodes face the ground level, are aligned along one continuous plane, are separated from each other at specified intervals in the horizontal direction, and are set to the same electrical potential. When the direct current high voltage is supplied from a power supply means, electric force lines are directed upward in the air above the applying means, producing charged particles based on corona discharge from the applying means. The charged particles absorb water in the air, condensing and binding into water, and dispersing the fog.

  • Patent number: 6116515
    Abstract: A method for making artificial snow using micro particulate material for the performance enhancement of snow making equipment, wherein very small particles of material are mixed into the water supply system which supplies water to the snow making guns at a skiing area. The particles serve as the nucleus for snow crystals to grow upon when sprayed into the atmosphere by the snow making guns. The water, which has the nucleating material mixed into it, is sprayed out of the snow making guns in the form of fine droplets, small enough for the cold ambient air at the skiing slope to freeze the small water droplets into the solid form of snow flakes. The nucleating material, which originally is in the form of a fine powder, may be mixed in a suitable container with a portion of the water, so it can be appropriately metered through a pump, into the water pipe that feeds the snow making guns.

  • Patent number: 6056203
    Abstract: Factors controlling the effect of cloud seeding were critically examined, and a new horizontal penetration seeding method using liquid homogeneous ice nucleants at the lower level of the supercooled portion of clouds was invented to maximize the microphysics-dynamics interaction between the seeded ice crystal thermal and the supercooled cloud through optimal utilization of the phase change energy. Cloud seeding tests showed a remarkable effect. This method allows the development of twin rotating horizontal cylinders of ice crystal thermal, which slowly rise, expand and entrain the supercooled cloud droplets to provide the supersaturated condition and time for the required growth of seeded ice crystals. When the thermal reaches the top of the cloud, it spreads horizontally while lowering the ice crystals of sufficiently large size and fall velocity resulting in an effective treatment of the existing and induced cloud volume for precipitation augmentation and the associated dynamic effect.

  • Patent number: 5975424
    Abstract: A new control circuit for firing an ultrasonic vertical anti-hail cannon on a repeated basis from a remote location. The control circuit employs a micro-controller with electrically erasable programmable read only memory and random access memory. When main power is provided the program is read from memory and several safety tests are run before the program goes into a routine that provides for repeated cannon firings. In the preferred embodiment a telephone pager is employed in the control circuit to enable repeated cannon fire by merely paging the cannon from a remote location. Likewise, the repeated cannon fire can be halted by paging the control circuit. The control circuit employs certain safety protocols to minimize the likelihood of inadvertent cannon fire and to permit manual firing and servicing of the cannon.

  • Patent number: 5957382
    Abstract: A fog generator comprising a pump which delivers under hitch pressure a volatilizable chemical into a centrifuge-heater component which centrifuges and heats the chemical efficiently. The centrifuge forces heavier particles of the volatilizable chemical against highly heated areas of the centrifuge member to provide added pressure to the volatilizable chemical passing through the centrifuge resulting in increased production of ultra-fine fog. One embodiment describes a fog generator which includes an ice chamber through which some of the volatilized chemical may be directed to cool the volatilized chemical passing through ice particles therein and make more effective the production of low-lying fog. To make the use of the ice chamber even more efficient, the ice chamber includes means for efficient removal of water which has accumulated from melted ice.

    Abstract: A method of dissipating hydrometeors (clouds) that includes transmitting electromagnetic radiation (e.g., light energy, from the sun, for example) that is absorbed by water vapor into the cloud to be dissipated and continuing the transmission of such energy into the cloud until it dissipates. The source of electromagnetic radiation can be a large mirror located on the surface of the earth, that reflects sunlight into the cloud to be dissipated. In a still more specific embodiment of the invention, the wind speed, direction, cloud altitude and sun movement relative to the earth is tracked to determine the mirror orientation and tracking necessary to disperse a particular cloud or clouds. In addition, an array of earth-mounted mirrors could be utilized in a coordinated fashion to dissipate a group or larger volume of clouds.

    Abstract: Weather in the vicinity of a land mass such as a continental arid zone near, and usually eastward of a body of water is modified by preferably propelling a ship pulling a submerged body having plurality of vertically displaced foils having an angle of attack that effects an upward displacement to the water in response to the surface displacement of the ship. The upward displacement of the water moves cooler sub-surface water toward the surface thereby cooling the surface water and reducing its heat loss in the summer. As a result, the heat capacity of the water is increased and additional heat will be stored in the water as a consequence of the greater absorption of solar radiation thereby increasing winter storms and the amount of rainfall over the land mass during the winter.

  • Patent number: 4643355
    Abstract: A fog generator comprises a duct which is preferably vertical and very tall, an air mover for moving air down through the duct, an air director which includes a spout to direct the air emerging from the duct in a substantially horizontal stream in a chosen direction away from the duct and a fog generator which generates a fog into the moving air preferably after the air has left the spout. The spout is preferably rotatable in a horizontal plane. The invention enables a generated fog to be placed where required by the air stream in which it is entrained rather than relying on natural wind drift.
