Abstract:
1. A dispersion and aeration apparatus including a nozzle portion having a first passage (air) having at least one inlet and a plurality of outlets for a first fluid and a second passage (foam) having at least one inlet and a plurality of outlets for a second material, each outlet from the first passage located such that the first fluid exiting said outlet mixes with the second material as the second material exits each second outlet, to aerate and disperse the second material in a predetermined direction wherein the second passage has a single inlet located at a first end of the nozzle portion and multiple outlets located at or near a second, opposed end of the nozzle portion and each of the multiple outlets is angled relative to the main longitudinal axis of the nozzle portion to promote spreading of the foam as it exits the nozzle portion to maximize the spread of the foam.
