    • Atmospheric occurrences that decrease visibility, particularly fog, smoke, smog and the like, are cleared at sites such as airports by an array of EGD spray units emitting submicron size charged water droplets to attach to airborne particulates and electrostatically precipitate those to ground. Independent variables of the array and the EGD jets from the spray units are controlled to control the dependent variables characterizing the space-charge cloud thus developed. The methods and apparatus control the height to which clearing of the airborne particulates occurs to improve visibility and the time required for such clearing. Specific compact spray units are self-contained, can be radio operated, and are movable. Placement of the units for removal of radiation and advection fog with respect to airport runways include a square array of the spray units proximate the runway for radiation fog control and upwind location of arrays for advection fog precipitation. Specific characteristics of small, medium and large spray units suitable for use in the arrays are set forth.

    • A tool (12) is releasably supported on a head (10) by a kinematic support (35) having elements (36,37) provided respectively on the head (10) and the tool (12) and extending in a plane (A--A) transverse to an axis (10A) of the head (10) by a releasable coupling (17) which comprises a first element (21) provided on the head (10) and engaged with a second element (26) provided on the tool. To release the tool (12) from the head (10) the latter is moved to position the tool (12) at a magazine (16) and by such movement to connect the second element (26) with an operating member (41) provided on the magazine (16). Rotation of the second element (26) by the operating member (41) releases the second element (26) from the first element (21) and frees the head (10) for withdrawal in the direction of its axis (10A). To connect the tool (12) to the head (10) the latter is moved in the direction of its axis (10A) to bring the elements (36,37) of the kinematic support (35) into proximity and to bring the coupling elements (21,26) into proximity. The operating member (41) is then rotated to connect the coupling elements (21,26) and establish engagement of the kinematic support (35). Thereafter the head (10) can be moved to remove the tool (12) from the magazine (16).

    • 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.

    • A method of supplemental irrigation of substantial areas, for supplying water to plants and for conserving water already in the plants and in the soil, by placing in the atmosphere over the area a fog of water particles which particles are of a size such that they tend to settle rather slowly. They will thereby have a residence time in the air around the plants, and can drift appreciable distances with slow air movement. According to the preferred method, the majority of the droplets will have a diameter between about 10 and about 200 microns, the mass median diameter being about 50 microns. The method comprehends generating this fog and, if necessary, blowing it to areas which require it.

    • A vortex generator including a heat source in the base of a cylindrical member with a circular ringwing in the shape of an airfoil which is lifted upward and then impulsively released to move rapidly downward and thus generate a vortex behind it. The vorticity in the core of the vortex is highly concentrated and moves rapidly upward through cloud cover. A strong light in the center of the vortex will shine to great heights making it especially useful as an airport beacon or the like. When the invention is used with a chimney, the effluents therein are caused to proceed rapidly upward through atmospheric obstacles such as thermal inversions which have been cleared by the action of the vortex.
