Abstract: An electrostatic spraying device comprises a capillary spray electrode having a spraying end, a reference electrode, and a reservoir in fluid communication with the spray electrode. In use, the electrodes are connected across a generator in order to establish an electric field between the electrodes and cause fluid in the reservoir to be sprayed from the spray electrode. The spray electrode has a focus that defines a point at which the electric field is focused on the spraying end.

Abstract: A sachet (1) having walls of flexible material is disclosed. The walls are joined so as to form an impermeable seal, thereby defining a cavity within the sachet (1). A conduit (2) passing through the seal and having inner and outer ends is disposed with the inner end within the cavity and the outer end outside the sachet (1) such that the cavity is in fluid communication, via the conduit, with the outside of the sachet. The cavity contains a volume of liquid (8) in use, and the conduit (2) is adapted to prevent the liquid (8) flowing from the cavity without the application of an additional stimulus, irrespective of the orientation of the sachet (1).

Abstract: An electrostatic spray atomisation device is disclosed. The device comprises a spray electrode disposed in a first recess in a dielectric surface, the spray electrode being connected, in use, in an electric circuit with a reference electrode enabling a potential difference to be applied between the spray and reference electrodes to atomise a liquid. Various techniques for dealing with problems of liquid deposition around the electrodes are described. The techniques may be used alone or in combination.

Abstract: A housing has a dispensing outlet (400) and contains: a liquid supplier (7) for supplying liquid containing at least one volatile component to a liquid outlet (7a); an electric field provider (41, 42, 7) for causing liquid issuing from the liquid outlet to provide electrically charged droplets from which at least a part of the at least one volatile component evaporates to produce vapour; a collection receptacle (92) for collecting electrically charged droplets to inhibit the electrically charged droplets from passing through the dispensing outlet; an attraction electrode (91) for attracting electrically charged droplets into the collection receptacle (90); and a flow director (95) for directing vapour away from the collection receptacle (92) and towards the dispensing outlet (400).

Abstract: The present invention provides a manufacturing process for quick dissolving products having active ingredients directed to agrochemical applications, such as plant applications and animal and animal health applications. Electrohydrodynamic (EHD) spraying is used to form a product form preferably comprised of fibers that contains a desired agrochemical compound formulated to quickly disintegrate on contact with a solvent such as water. The dispersed chemical is then provided as a sprayable solution. Because the product form contains little or no liquid, significant size and weight savings are gained, higher active ingredient loadings may be placed in a smaller amount of material, and manufacturing, packaging and transportation costs are thereby reduced without impacting user-friendliness. In addition, the EHD manufacturing method of the present invention also permits combining active ingredients previously not capable of effective use together in a single product.
