From Patent Document:
"This invention relates to a device for mixing two or more fluid feed materials and dispensing the resulting composition. The feed materials will ordinarily be liquids, or one may be a gas; they may or may not be reactive with one another; and the resulting composition may therefore be a mixture or a compound. However, the invention is particularly useful for the mixing of viscous liquids which react to form a viscous or solid product, e.g. a synthetic resin, and for dispensing or delivering this product to a desired location. The product, if a resin for example, may then harden in that location to its final polymerized condition."
