Abstract: A non-drip hygiene dispenser for dispensing a wipe paper-towel while keeping a clean and sterile working area comprises (a) a wipe paper-towel, (b) at least one reservoir containing liquid, (c) a first stream of compressed air, (d) a second stream of compressed air, an anti-dripping nozzle, (e) rolling means, and (f) cutting means. The anti-dripping nozzle further comprises activating means and a dispensing tip. The activating means comprises a retractable anti-drip needle backed by a spring. The spring retracts backwards when compressed air of the first stream of compressed air presses the spring, thus retracts the anti-drip needle, and thus, unblocks the dispensing tip to allow liquid from the at least one reservoir to flow through the dispensing tip. When the compressed air pressing the spring is released, the retractable anti-drip needle returns to its original place, blocking the dispensing tip to block the passage of liquid remained in the dispenser immediately upon shut off of the dispenser, thus, to avoid undesired dripping. The second stream of compressed air entering the anti-dripping nozzle mixes with the sprayed liquid in order to form a foggy environment around the wipe paper-towel.

Abstract: A spray gun has at least one air valve that can be actuated by at least one trigger, having at least one valve inlet region and at least one valve outlet region. The spray gun has at least one material valve designed in such a way that it can be pneumatically actuated by air from the at least one valve outlet region. With this design, the force to be exerted to actuate the actuation element by the user of the spray gun is significantly lower than in prior spray guns, which allows for effortless operation.

Abstract: A spray ionization device comprising: a first pipe body that has a first flow path which allows a liquid to flow therethrough, and has, at one end thereof, a first outlet through which the liquid is sprayed out; a second pipe body that surrounds the first pipe body; and a third pipe body that surrounds the second pipe body with a space interposed therebetween, that has a second flow path allowing a gas to flow therethrough, and that has a second outlet at the one end. At least the leading end part of the third pipe body including the second outlet is made of an electrically conductive material so as to serve as an electrode. Charged droplets can be sprayed from the second outlet by applying an electric field to droplets sprayed from the first outlet using a power supply connected to the electrode.

Abstract: Methods of servicing a fuel nozzle are provided. a method of servicing a fuel nozzle includes a step of machining away material from a nozzle tip of the fuel nozzle to form an annular groove within the nozzle tip. The method further includes a step of inserting a replacement coupon into the annular groove. The replacement coupon having a radially outermost that corresponds to the annular groove and a post-removal contact surface. The method further includes a step of fixedly coupling the radially outermost of the replacement coupon to the annular groove.

Abstract: A pneumatic cleaning gun according to the present invention comprises a gun housing with a compressed air connection, a liquid nozzle with a nozzle cover, and an air intake tube which leads into the covered flow channel and can also be connected to a suction device via a suction hose in order to suction dirt particles through the flow channel. The cleaning gun is configured such that the air intake tube is not rigidly but pivotably mounted on the cleaning gun. The air intake tube can therefore be mounted in a plurality of different positions of use such that the user can find the most comfortable or convenient position of use and the air intake tube can be correspondingly adjusted.

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.
