ABSTRACT:
Foam producing apparatus comprising a container adapted to receive a small amount of chemical solution in its bottom including means for converting said solution into an extremely large volume of relatively "dry" foam. In connection with the container are series related means uniquely formed and arranged to wring and extract liquid from the bubbles of the foam at successive intervals in the course of its flow.
Preferred applications of the invention contemplate the use of the "dry" bubbles of the foam as a vehicle for various chemicals such as weed killers, insecticides and fertilizers which will have the capability of an adherent deposit of the chemicals without significant dilution of their required strength.
