Abstract: Method for absorbing, removing, and for cleaning up a first liquid floating on or in a second liquid, the method employing absorbent pellets which, in preferred embodiments, have a particular size, density, and configuration. The method can include steps of introducing the pellets onto or into the floating liquid to be removed; in preferred embodiments additional steps of agitation and spraying or applying a surfactant can be employed. The pellets containing the liquid to be removed can be removed from the surface of the second liquid; from an intermediate location above the lowermost depth of the liquid; or from the bottom level of the liquid or the bottom of the container or reservoir holding the liquid. A method for making pellets for cleaning up a first liquid floating on or in a second liquid; and a method for making pellets for absorbing a combustible material to produce fuel pellets. A method for producing fuel pellets.

Abstract: A spray nozzle for spraying a mixture of fibrous insulating material and an adhesive for the fibrous insulating material. The nozzle has a hollow cylindrical body, a material conditioning chamber with a larger cross sectional area than the hollow cylindrical body, a generally conical spray hood adjacent the material conditioning chamber, a mixing chamber in the spray hood, and an adhesive feed line connected to and extending into the spray hood. The adhesive is homogeneously mixed with the fibrous insulating material in the spray hood.
