Claim 5
Independent Claim
123 words
An apparatus for dispersing smoke and the like, said apparatus comprising a vertical smoke stack having an exit opening at the top thereof and an entrance port at the bottom thereof; means for introducing smoke into port stack and means for causing the smoke to exit from the exit opening of the smoke stack in pulsed interrupted flow thereby forming smoke rings; and wherein the means for causing the smoke to exit from the smoke stack in pulsed interrupted flow thereby forming smoke rings comprising a nozzle in the lower portion of the smoke stack and means for forcing a pulsed stream of gaseous material through the nozzle; and wherein the pulsed stream of a gaseous material is a pulsed stream of air.
Claim 6
Independent Claim
123 words
An apparatus for dispersing smoke and the like, said apparatus comprising a vertical smoke stack having an exit opening at the top thereof and an entrance port at the bottom thereof; means for introducing smoke into port stack and means for causing the smoke to exit from the exit opening of the smoke stack in pulsed interrupted flow thereby forming smoke rings; and wherein the means for causing the smoke to exit from the smoke stack in pulsed interrupted flow thereby forming smoke rings comprising a nozzle in the lower portion of the smoke stack and means for forcing a pulsed stream of gaseous material through the nozzle; and wherein the pulsed stream of a gaseous material is a pulsed stream of air.
Claim 7
Independent Claim
115 words
An apparatus for dispersing smoke and the like, said apparatus comprising a vertical smoke stack having an exit opening at the top thereof and an entrance port at the bottom thereof; means for introducing smoke into the entrance port of the smoke stack and means for causing the smoke to exit from the exit opening of the smoke stack in pulsed interrupted flow thereby forming smoke rings; and wherein the means for causing the smoke to exit from the smoke stack in pulsed interrupted flow thereby forming smoke rings comprises a sparge ring in the lower portion of the smoke stack and means for forcing pulsed stream of a gaseous material through the sparge ring.
Claim 8
Independent Claim
115 words
An apparatus for dispersing smoke and the like, said apparatus comprising a vertical smoke stack having an exit opening at the top thereof and an entrance port at the bottom thereof; means for introducing smoke into the entrance port of the smoke stack and means for causing the smoke to exit from the exit opening of the smoke stack in pulsed interrupted flow thereby forming smoke rings; and wherein the means for causing the smoke to exit from the smoke stack in pulsed interrupted flow thereby forming smoke rings comprises a sparge ring in the lower portion of the smoke stack and means for forcing pulsed stream of a gaseous material through the sparge ring.
