摘要： An atomization technique which involves the movement of a film of liquid, such as water, over both surfaces of the blades of a multibladed fan rotating about its hub. The liquid is fed in an annular stream or annular series of jets to the rotating blades near the hub of the blades. The leading edge of each blade cuts into the stream and picks up a portion of the liquid. The liquid then travels over both surfaces of each blade progressing from leading edge to trailing edge and also, because of centrifugal forces, outboard from the hub. As the liquid comes off the trailing edge of each rotating blade, it is atomized to the droplet size desired; the droplet size being a function of parameters such as rotational speed, quantity of water fed to the rotating blades, and length of trailing edge. There is also specifically disclosed the application of the invention to snowmaking. In snow-making, the movement of air over the surface of the film of water, that in turn is moving over the surfaces of each blade, causes evaporation. This evaporation cools the water down to somewhere between 10* F. and 15* F., at which temperature the atomized droplets that come off the trailing edge of the blades will, under proper ambient conditions of temperature and humidity, form particles of snow.

摘要： A method of making snow by controlling the size and life of ice nuclei generated in a snow-making machine. Ice nuclei are generated by homogeneous nucleation in a tunnellike housing through injection of propane or other refrigerant into a stream of moist air. The relative humidity about the ice nuclei stream is controlled relative to the temperature and humidity of the atmosphere to prevent or inhibit evaporation of the ice nuclei for such time as to ensure statistically effective mixing with adjacent liquid phase water droplets which are supercooled by the air mass. The ice nuclei formed infect the water droplets and they release their latent heat to the air to form snowlike particles.

摘要： A snow making system, suitable for making man-made snow for ski-runs or ski-slopes, uses a snow making machine, where ice is converted into snow-like particles and directed in an upwardly-directed stream, into which a spray or mist of water droplets is introduced. The snow-like particles operate as nucleating agents for the water droplets to convert the droplets into flakes of snow. The flakes of snow may be introduced into the snow making machine, converted into snow-like particles and be incorporated into the stream to produce further flakes of snow. The flakes of snow can be “recycled” to the snow making machine until the desired quantity of snow has been produced. The system enables snow to be made at ambient air temperatures just above, or below, the freezing point of water.

摘要： A hydrant for selectively valving and delivering fluid under pressure to a plurality of different fluid outlets at a plurality of preselected flow rates. The hydrant is provided with a multiple port valve including a hydrant valve housing having at least one fluid inlet and multiple fluid outlets of different flow rate. A valve operating shaft is mounted for axial rotation in the hydrant housing and positioned transversely to a valve seat having a first set of valve ports therethrough annularly arranged on a first circumference about the shaft, and a second set of valve ports are provided through the valve seat and annularly arranged on a concentric second circumference of different diameter than the first circumference about the shaft. The valve ports are connected respectively to the fluid outlet ports. A valve actuator disk secured for rotation with the operating shaft slidably engages the valve seat in a rotary fasion to selectively valve the valve ports open and closed in selected combinations with rotation of the shaft to preselected positions of rotation.

摘要： 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.

摘要： An air flow assembly, such as a fan assembly, and associated methods are shown that may include one or more media dispensing nozzles. Examples of assemblies and methods are shown that include nozzles located within hollow vanes. Other examples of fan assemblies and methods are shown that create multiple cross sectional vortices that may be useful to concentrate a dispersed media.

摘要： Disclosed is an improvement of a bubble-type snowflake maker. The interior of a machine body of a main machine is provided with accommodating space for disposing a blower that is used to send out wind power towards an air outlet pipe and an air outlet; a pump transports bubble water to a bubble head along a flexible bubble water pipe; a tail end of the air outlet pipe is sleeved with a cloth sleeve extending outwardly, and the bubble head of the bubble water pipe is disposed in the air outlet pipe; the air outlet is outwardly connected to a spray pipe having an inner pipe, and the air outlet pipe and the cloth sleeve extend into the pipe; the inner diameter of the inner pipe of the spray pipe is greater than the outer diameter of the air outlet pipe; and an inner annular toothed edge radially extends inwardly along a tail end of the inner pipe of the spray pipe. Wind power generated by the blower is blown to the interior and exterior of the cloth sleeve through the air pipe and the air outlet separately, so that the bubble water exudes from a surface of the cloth sleeve to form bubbles, and the wind power is used to blow the bubbles to fly away, so as to form artificial snowflakes.

摘要： Various embodiments of modular dual vector fluid spray nozzles are disclosed. Embodiments of the nozzles are characterized by specially shaped fluid channels, impingement surfaces and exit orifices used to generate atomized mists of fluid under pressure. Embodiments of the nozzles are generally characterized by composite fluid spray density patterns having horizontal and vertical components, i.e., dual vector in nature. The nozzles disclosed are modular and may be easily installed or removed from a given fluid spray system, nozzle head, or fixture as dictated by any given application.
