20080254529 | BIOMASS CULTIVATION SYSTEM AND CORRESPONDING METHOD OF OPERATION - A liquid culture medium containing photosynthetic organisms dispenses from a droplet generator combined with a screen in the presence of light, and in the presence of a gaseous medium to form a liquid culture medium gas-enriched with the gaseous medium.

20120129242 | Falling Film Evaporator - An apparatus and method are disclosed for controlling the thickness of a flowing, laminar fluid film. The film flow may be gravity-induced or the result of an alternative force. The fluid is deposited on an upper end of a flow surface where a relatively thick layer of the film forms. The film flows over a fluid dispersal region where the surface area is rapidly expanding, which results in rapid thinning of the film thickness. The fluid then flows over an active region where the surface area is designed to control the fluid film thickness.
