Abstract: A sanitary functional unit having a sleeve-shaped insert cartridge insertable into the pipe-shaped fixture outlet of a sanitary outlet fixture is provided. The insert cartridge has a water inlet at the cartridge circumference and a jet former having flow guiding walls oriented transversely to the cartridge longitudinal axis provided in the water outlet. The functional unit deflects the water jet flowing in from the axial direction such that water subsequently flows out of the fixture outlet in a nearly radial direction. The functional unit has a jet former, provided in the region of the water outlet, supporting flow guiding walls that are oriented transversely and perpendicularly to the cartridge longitudinal axis. Since the functional unit is oriented approximately coaxially to the fixture outlet, it also does not project beyond the pipe circumference of the fixture outlet.

Abstract: This invention generally relates to systems and methods for the formation and/or control of fluidic species, and articles produced by such systems and methods. In some cases, the invention involves unique fluid channels, systems, controls, and/or restrictions, and combinations thereof. In certain embodiments, the invention allows fluidic streams (which can be continuous or discontinuous, i.e., droplets) to be formed and/or combined, at a variety of scales, including microfluidic scales. In one set of embodiments, a fluidic stream may be produced from a channel, where a cross-sectional dimension of the fluidic stream is smaller than that of the channel, for example, through the use of structural elements, other fluids, and/or applied external fields, etc. In some cases, a Taylor cone may be produced.
