Abstract
Abstract 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.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
80 words
A vortex ring generator for use in clearing atmospheric obstacles in the path thereof, said vortex generator comprising a circular cylinder having a heat source in the base thereof, a ringwing surrounding the upper portion of said circular cylinder, and means for periodically raising and rapidly lowering said ringwing at a predetermined frequency rate to create a vortex therebehind, said vortex being highly concentrated for rapid upward movement thereby clearing the atmosphere for relatively great distances above the vortex generator.
Claim 2
Dependent Claim
80 words
A vortex ring generator for use in clearing atmospheric obstacles in the path thereof, said vortex generator comprising a circular cylinder having a heat source in the base thereof, a ringwing surrounding the upper portion of said circular cylinder, and means for periodically raising and rapidly lowering said ringwing at a predetermined frequency rate to create a vortex therebehind, said vortex being highly concentrated for rapid upward movement thereby clearing the atmosphere for relatively great distances above the vortex generator.
Claim 3
Dependent Claim
19 words
The vortex ring generator defined in claim 1 wherein said ringwing is configurated in the shape of an airfoil.
Claim 4
Dependent Claim
52 words
The vortex ring generator defined in claim 2 wherein the means for raising and lowering said ringwing includes a motor driven chain on said circular cylinder for periodically raising said ringwing to a position at the open upper end of said cylinder and a plurality of springs for rapidly lowering said ringwing.
Claim 5
Dependent Claim
72 words
The vortex ring generator defined in claim 2 wherein the means for raising and lowering said ringwing includes a plurality of double-acting hydraulic cylinders operatively connected to said ringwing, such that the introduction of fluid under pressure to one end of said hydraulic cylinders causes said ringwing to move upward and the introduction of fluid under pressure to the other end of said hydraulic cylinders causes said ringwing to move rapidly downward.
Claim 6
Dependent Claim
42 words
The vortex ring generator defined in claim 2 wherein a light source is positioned in the lower end of said circular cylinder, said light shining through the atmosphere above said circular cylinder cleared by said vortex thereby serving as an airport beacon.
Claim 7
Dependent Claim
48 words
The vortex ring generator defined in claim 2 wherein said circular cylinder operates as a chimney and said vortex generator is attached to the upper portion thereof, thereby clearing the atmosphere to allow effluents from the chimney to reach relatively great heights after being propelled by the vortex.
