    Abstract: A sprayer device including a generator for generating an air stream having a predetermined velocity and a nozzle unit for the discharge of liquid therefrom, whereby to produce a mist stream capable of being propelled to a predetermined location. The mist stream has a measurable and controllable lateral dimension at the predetermined location. The sprayer device is used particularly for moistening cattle, especially cows, in sheds, and taking into account the effect of the wind. Rows of sprayers project water sprays directed toward the cattle. The sprayers may be angularly shifted to take into account the deviating effect of the wind. A processor calculates the angular shift that is needed for the existing wind direction and intensity. All the sprayers concurrently receive the angular shift, which is transmitted to the first sprayer from a control station and successively from each sprayer to the next.

  • Patent number: 7534404
    Abstract: New methods of operating surface reactors, and such reactors, particularly spinning disk reactors, require that a first reactant is fed to a reactor surface (20) and forms a thin radially outward moving film (60) thereon in a reaction passage (42) formed between the reaction surface (20) and a parallel, closely spaced (less than 1 mm) retaining surface (40). The passage thickness is precisely controllable and the surfaces (20, 40) move relative to one another so that strong shear is applied to the material between them. A second reactant is fed to the surface (20) as a second thin film (65) that as it enters the first film (60), preferably perpendicularly, it is immediately merged therewith along a correspondingly very narrow interaction line (66) by the shear at a rate such as to break up molecular clusters in the films, so that their molecules can aggressively and completely interact by forced interdiffusion.

  • Patent number: 6062546
    Abstract: A method and apparatus for the transfer of mass with the aid of rotating surfaces. The fluid with which an exchange or transfer is to be made is introduced in parallel in one or more gaps or channels defined between the rotating surfaces. Rotation of the surfaces causes the major part of the fluid flow to pass through a rotating, flow mechanical boundary layer adjacent the rotating transfer surface in laminar or turbulent flow.

  • Patent number: 5851271
    Abstract: A device for simultaneously filtering and humidifying an air flow uses an outer casing having a rotatable, reticulated filtering element. The air flow enters the casing and must pass through the filtering element by making abrupt change in directions. Particles in the air flow, due to their greater inertia, will not be able to follow the air flow and, therefore, will not pass through the filtering element. There are expelled through an opening. The air flow exists through an outlet that is within the perimeter of the filtering element. A water projector serves to both humidify the air flow and wetten the filter elements surface in order to capture particles in the air flow.

  • Patent number: 5837167
    Abstract: A compact portable misting fan includes a novel and attractive housing which makes extremely efficient use of space, encased fan blades which are mounted between front and rear baffles, a liquid reservoir with an atomizer, conveniently located mist and fan controls, and an easily accessible battery compartment. The housing has a substantially flat profile with a substantially cylindrical upper section in which the fan is mounted and a substantially rectilinear lower section in which the reservoir and batteries are contained. The fan on/off switch is located on a lower portion of the cylindrical upper section and the misting button is located on an upper portion of the rectilinear lower section and on a side opposite to the fan switch. It is easily held in the user's hand so that the fan and the mister can be operated separately by thumb or index finger. A small hole is provided in the housing for the outlet of the atomizer.

  • Patent number: 5704954
    Abstract: The air purification apparatus includes a waterproof chamber having a water supply inlet, a drain, an air inlet, and an air outlet. At least two cylinders are mounted to spin about their respective axes within the chamber in parallel alignment adjacent to each other, and a motor drives each of the cylinders to rotate at high speed. The surfaces of the cylinders have numerous small holes formed therein. A pump circulates water through the water supply inlet to the inside of each of the cylinders. By rotating the cylinders at high speed, the water pumped to the inside of each of the cylinders is injected by centrifugal force through the numerous small holes therein at high speed such that streams of water droplets are forced to collide against each in the typhoon chamber and particularly between the cylinders. These forceful collisions produce infinitesimally small water particles with negative ions that have high air purification ability. An air blower circulates air through the chamber for purification.

  • Patent number: 5482108
    Abstract: The invention relates to a method for achieving an optimal energy exchange in regenerative heat exchange between the combustion air and precooled, wet flue gases from a cooling device. By letting the moisture in said flue gases be condensed on the heat transfer surfaces the moisture will be transferred over to the air side where it is vaporized, resulting in some advantages, e.g. an increased energy exchange. According to the invention it has turned out to be possible to achieve a further increase of the energy exchange in a simple way by ensuring that the heat transfer surfaces of the flue gas side become really water-soaked when on the flue gas side, e.g. by letting the condensed water from the precooling device (15) drip or flow down onto the heat transfert surfaces such that said surfaces will remain wet during the entire passage through the combustion air side (10).

  • Patent number: 5439618
    Abstract: A water atomization system for cooling, aeration, and pollution control gas scrubbing, wherein a multiple blade fan is mounted in a tower cap, or positioned directly inside of a tank or tower. Water exiting nozzles impinges off the fan blades, thereby propelling and rotating the fan. The rotating fan atomizes the water into fine droplets, and forces air through the atomized water. For cooling and aeration applications, heat or dissolved gasses in the water are liberated and carried away by the flowing air. The system can also be used for pollution control, whereby instead of air traveling through the device, gasses of combustion flow through it. The water traps, absorbs, and chemically reacts with suspended particles in the flowing gasses.
