Abstract: A high volume aeration device comprises a motor and propeller tube suspended in a pond by a float. A propeller on the motor shaft and inside the propeller tube creates a generally hollow water output stream that rises out of the propeller tube. A diffuser plate is longitudinally slidable inside the hollow water output stream. The water output stream strikes the diffuser plate and locates it at an equilibrium location whereat the force of the water output stream on the diffuser plate periphery equals the weight of the diffuser plate. If the propeller cavitates, the reduced water output stream causes the diffuser plate to fall toward the propeller and redirect the water output stream to the propeller. The redirected water output stream reloads the propeller and enables the aeration device to resume full output without outside intervention after the cause of the cavitation has been eliminated.

Abstract: A device for increasing the evaporation of liquid from mud pits is disclosed having an elongated collection tank suspended from flotation means for holding a quantity of the liquid. A plurality of riser pipes extending from the collection tank to the surface of the liquid, each of the riser pipes having a nozzle connected to the end thereof capable of converting the liquid into a hollow, conical spray having ultrafine droplets.

Abstract: A method and apparatus for the provision of cooling through the utilization of aerosol sprays is disclosed. The hot water output of a load device is stored until low ambient temperatures exist, whereupon the hot water is atomized and exposed to the ambient air to be cooled thereby. A spray cooling system can also be combined with an artificial ice making system to provide even lower load device input temperatures. Specialized insulating devices can be used in connection with the artificially made ice to decrease the heat transfer between the ice and the ambient air during warm weather.

Abstract: This invention provides for a system for the year-round aeration of lagoons, ponds, small lakes and the like, providing greatly improved circulation and saturation of effluent with dissolved oxygen, further providing advantages of portability and remote location of inlet, discharge and pump; and utilizing a device incorporating internal baffles within an adjustably inclined chute incorporating covers and discharge extension and movable mounted upon a suitable vehicle.

Abstract: A portable auxiliary cooling tower which is transportable over-the-highway for temporary or permanent use at a desired site. The tower is typically constructed on a trailer frame and is designed to provide maximum air flow for maximum cooling to temporarily replace or supplement larger fixed cooling tower cells. Another use of the portable cooling tower is to aerate stock ponds, chemical holding ponds and the like.

Abstract: A live bait water aerator comprises a submergible water pump, a conduit attached to the water outlet of the pump, leading vertically upward above the water surface, ending in a water delivery head having a plurality of delivery holes set at an angle relative to the surface of the water. A method of aerating water in a live bait container which comprises drawing water through a three-chambered submergible electrically powered water pump, passing the water through a conduit ending above the surface of the water, delivering a plurality of streams of water through a cylindrical delivery head onto and below the surface of the water in which the pump is submerged thereby trapping air bubbles below the surface of the water.

Abstract: A liquid cooling apparatus having a multi-level terraced structure capped by a central cooling tower. The central cooling tower has one or more non-clogging liquid spray nozzles mounted therein for spraying the liquid in the tower while compressed air is fed into the bottom of the tower into the sprayed liquid. The liquid collects on the terraced structure which has a plurality of channels formed therein having baffles mounted to break up the flow of water as it passes over each level of the terraced structure. Flow paths on the terraced structure may also have rocks placed along the channels between the baffling members.

Abstract: An integral water purification system including a tank for containing unclean water located at the source with continual replenishment of said water in the tank, a cover for the tank to accumulate natural heat by the elimination of any disturbances by the elements and to aid such accumulation by the rays of the sun in order to vaporize the unclean water, a blower for moving the vapor to a pipe leading from an area of one temperature to an area of another and lower temperature such as from the crest to the depth of the sea, whereby the vapor is condensed into droplets and accumulated in a condensing unit as pure water and a pump to force the water from the final condenser to a fresh water storage tank for later use whereby potable water is obtained from unclean water with the use of natural forces and with a minimum of expenditure of artificial energy sources.

Abstract: A system for spray cooling large quantities of heated water has a plurality of spray forming means each consisting of a plurality of associated nozzles connected by piping to pumps, each of the associated nozzles having an outlet constructed and arranged to discharge the water in a coherent stream which impinges upon the stream ejected by each other associated nozzle in a common zone beyond the nozzle with a force which breaks the streams into a spray of drops having a resultant trajectory away from the nozzles into a receiver. The water may be aerated before discharge from the nozzles, this being effectively accomplished by means of air inlets to a venturi passage in each nozzle.

Abstract: A water distribution system is disclosed which employs a plurality of spray nozzles arranged to induce air flow and maximize the cooling surface area of the falling water. The plurality of spray nozzles are arranged along a plurality of vertical planes and a plurality of horizontal planes.The nozzles are located on at least two sides of a central area and are adapted to spray the water to be cooled toward the central area.
