摘要： An artificial snowfall system comprises a snowfall room (2) in which are properly disposed a snow catching element (4) made of materials excellent in gas permeability and an atomizer unit (8) for ejecting atomized particles of liquid into the room (2). The atomized particles are frozen by heat exchange with ambient air within the room (2). The ambient air is kept at a temperature of below a freezing point of the liquid and forms an air flow passing through the snow catching element (4). The air flow causes the frozen particles to be deposited on one side of the catching element (4) to form a snow layer thereon. A beater element (9) for beating the other side of the catching element (4) is oppositely disposed from the other side to have the snow layer separated from the catching element (4). The thus separated snow layer creates artificial snowfall in the room (2).

摘要： The disclosure relates to a method for making artificial snow involving the induction of compressed air into an annular disposed chamber and through a multitude of circumferentially and longitudinally spaced, radially inward directed orifices to be mixed with a steady stream of water. The mixture is then forced through a multitude of longitudinal directed orifices, where a substantial pressure drop subsequent to egress from the orifices causes a first stage atomization of the water into tiny, uniformly sized droplets and the concurrent pre-cooling of the droplets. The droplets are ten accelerated through an exit nozzle, where the final expansion of still partially compressed air to atmospheric pressure causes the final atomization, and the projecting of a thereby produced plume of water droplets through an trajectory within the cooler atmosphere along which the droplets are allowed to freeze into tiny, crystalline particles of ice before falling to the ground.

摘要： A concentric multiple tube assembly forms an axial eductor passage for educed ambient air flow unobstructed from the inlet end to the outlet end. Ambient air eduction occurs as a result of ejection of compressed air or compressed air and water via at least one set of compressed air and water ejection orifices oblique to the inner tube sidewall defining the eductor passage and at a skewed trajectory angle such that the compressed air streams attach to the inner tube side wall opposite the orifices ejecting the same via Coanda effect. By wall attachment, a water film on the tube inner wall enhances the cooling effect of the air stream passing therethrough by evaporation thereof. Compressed air and water are delivered to annular chambers within the tubular assembly. Preferably, water mixes with the compressed air in one of the chambers prior to ejection into the eductor passage. A circumferential set of outlet end air and water ejection nozzles eject compressed air and water in jet form at circumferentially spaced positions parallel to and about the air/water stream discharging from the outlet end of the assembly.

摘要： Disclosed herein is a self-regulating hydrant which is characterized by a mechanism which automatically alters the flow of fluid through a valve seat in response to changes in ambient temperature. A temperature-responsive member, operatively coupled to a valve plug, is used to control the position of the plug relative to a valve seat. As the temperature of such member changes, its dimensions change. Such dimensional changes are preferably amplified and used to move the plug relative to the valve seat to control the rate of fluid flow through the valve seat.

摘要： The compressed-air supply line of the snow gun passes through the center of the pressurized-water supply line, thus bounding an annular chamber between them. Inner nozzles forming part of the air line interconnect the two supply lines. The compressed-air supply line opens out into an interior space within the spray head, this space being bounded at the front end by a perforated end piece. For the purpose of reducing the expenditure of energy for a given homogeneity of the air-water mixture, the radial width of the annular chamber in the vicinity of the inner nozzles is from one to three times greater than the diameter of an imaginary bore whose area corresponds to the total area of all inner nozzle bores, divided by three.

摘要： The invention comprises an atomizing spray nozzle having an expansion chamber containing an impingement plate, or table and wherein a flow of liquid is introduced as a high velocity stream which strikes the impingement table and breaks up into finely atomized particles which are struck by a high velocity air stream in a direction at an angle to the direction of the liquid stream to further atomize the liquid particles as the mixture atomizes adjacent the impingement table and passes into a mixing area in the barrel of the nozzle. The nozzle includes a jet forming inlet for the liquid aimed from one side of the nozzle at the impingement table in the expansion chamber, an air inlet orifice member secured in one end of the nozzle at an angle to the liquid inlet and at one side of the expansion chamber with the nozzle barrel at the downstream side of the expansion chamber and an exit orifice member secured in the open discharge end of the barrel.

摘要： A snow-making nozzle assembly which is very effective in producing uniform, small, highly atomized droplets of liquid that freeze to form snow is disclosed. The nozzle assembly in accordance with the present invention is comprised generally of opposed pairs of water outlets spaced at the periphery of a generally fan-shaped convergent-divergent compressed air nozzle. The water streams emitted from the water outputs impinge on each other and atomize substantially without contacting the walls of the nozzle. These liquid particles are entrained in the compressed air stream for further atomization and for distribution into the ambient air. The use of the nozzle in accordance with the present invention results in greatly improved snow-making capabilities when compared with prior art devices.
