The inclined passage is angled to diverge from the longitudinal axis of the distributor body in a direction toward the downstream end.

Abstract: The present invention is a method and apparatus for conducting transactions regarding similarity of products against a repository in which products are grouped in clusters according to their characteristics. A product suite repository interface facilitates such transactions. Such a repository is useful for consumers and participants in the supply chain. For example, a supplier could determine which products in its own offerings are related to those offered by a retailer. Partners in some effort might merge their offerings into a single catalog. A consumer might use the repository to find accessories that might enhance a purchased item.

Abstract: An atomizer includes an atomizer body having a liquid inlet and a spray outlet with a liquid flow circuit defined through the inner atomizer body for fluid communication of liquid from the inlet to the spray outlet. The liquid flow circuit branches into a plurality of sub-circuits. Each sub-circuit is configured to produce a spray cone of atomized liquid issuing from the spray outlet such that the spray cone of each sub-circuit has a different cone angle. The sub-circuits are mechanically separated from one another to limit interaction of liquid in the sub-circuits and thereby produce a distinct and stable spray cone from each sub-circuit over a range of liquid flow rates.
