    Abstract: A liquid spray device prevents diffusion of a poisonous gas and odor in a sprayed liquid. A base includes an ejection orifice for ejecting acidic water, first and second feed paths communicating with ejection and spray orifices to feed acidic and alkaline water, respectively. The second feed path is open so that its front end continuously makes a circuit on the side surface of the base. A rotary part is disposed to rotate along the side surface of the base. The rotary part includes the spray orifices disposed to surround the periphery of the ejection orifice. The rotary part includes communication paths communicating with the respective spray orifices and the second feed path. The respective spray orifices spray alkaline water while rotating around the periphery of the ejection orifice to surround the periphery of acidic water ejected from the ejection orifice with the alkaline water in a curtain-like manner.

    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. In another set of embodiments, a fluidic stream may be manipulated in some fashion, for example, to create tubes (which may be hollow or solid), droplets, nested tubes or droplets, arrays of tubes or droplets, meshes of tubes, etc. In some cases, droplets produced using certain embodiments of the invention may be charged or substantially charged, which may allow their further manipulation, for instance, using applied external fields. Non-limiting examples of such manipulations include producing charged droplets, coalescing droplets (especially at the microscale), synchronizing droplet formation, aligning molecules within the droplet, etc. In some cases, the droplets and/or the fluidic streams may include colloids, cells, therapeutic agents, and the like.

    Abstract: A droplet generating device for use as part of a continuous inkjet printer comprises a set of channels for providing a composite flow of a first fluid (11) surrounded by a second fluid (12) and an expansion cavity (3) having an entry orifice (2) and an exit orifice (4). The cross sectional area of the cavity is larger than the cross sectional area of either orifice such that the composite flow breaks up to form droplets of the first fluid within the second-fluid within the cavity, the exit orifice also forming a nozzle of an inkjet device, the passage of the droplets of the first fluid through the exit orifice causing the composite jet to break into composite droplets.
