Abstract: A floating liquid layer detection and recovery apparatus and process are disclosed for selectively siphoning and storing a floating or sinking liquid layer and more specifically to an apparatus for raising floating hydrocarbons on groundwater or surface water to a higher point in a semi-closed system without a pump or an outside energy source once the apparatus is in place. In conjunction with this apparatus an apparatus is provided to create a cone of depression without a pump or outside energy source. Thicker floating liquids are siphoned to a higher point to a tank where water is first occupied and are separated by specific gravity. The water, being heavier, completes the remaining segment of the siphon to a point at or below the point of origin. Thinner floating liquid layers are siphoned under the lower end of a downcomer tube by capillary action along a fibrous media where capillary action of the lighter liquid continues upward joining the first siphon flow directly to the tank.

Abstract: A snowmaking apparatus is formed of a concentric tubes to define an outer flow passage and an inner circular passage with water carried within the inner flow passage ejected across a pressure compensated annular gap defined by the end of the inner tube and the confronting surface of a spring biased nozzle disk tending to close off that annular gap. The same nozzle disk defines a second annular gap between the nozzle disk and an annular ring fixedly mounted within the outer flow passage has an end face confronting the end face of the nozzle disk.

Abstract: 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.
