Abstract: A liquid dispensing element is provided. The element comprising; a dispensing plate comprising a plurality of orifices; the dispensing plate at least partially defining a fluid flow path; a plurality of piezoelectric transducers each comprising a piston configured to move perpendicular to the dispensing plate between a first position wherein the piston is close to the dispensing plate and a second position wherein the piston is further from the dispensing plate. The movement between the first and second positions results in the ejection of a droplet of fluid via a surface cavitation droplet ejection process such that the diameter of the droplet is less than a diameter of the orifice.

Abstract: An industrial printhead (100) comprising a flow channel enclosed in a chamber, wherein the flow channel (102) has at least one fluid inlet (102a) and at least one fluid outlet (102b), wherein the flow channel is resonated, in use, by a vibration distributor (104) comprising a mass resonator (103), piezoelectric exciter (108) and wave concentrator (110) arranged in an axial configuration.

Abstract: Systems for applying a masking material to a substrate, the system comprising: a source feed for delivering a quantity of masking material to a substrate, a waste deposit for receiving masking material when removed from the substrate, a spray nozzle moveable relative to the substrate and a controller for controlling movement of the nozzle relative to the substrate and the speed of delivery of the masking material from the source feed, wherein the speed of movement of the spray nozzle relative to the substrate is substantially equal to the speed of delivery of the masking material from the source feed.

Abstract: Method for producing a digitally printed decorative coating on a solid surface, comprising the steps of: applying solid pigment dye (2) to the surface (1) and treating the coating such that the treatment results in the setting/hardening of the coating, where at first the dry surface (1) is evenly coated applying solid pigment dye (2) at least over the surface portion where the coating is to be applied, in a subsequent printing operation liquid is applied to the surface (1) coated with dry pigment dye (2), thereby temporarily fixing the solid pigment dye (2) to the printed-on surface portions, and before performing the treatment resulting in the setting/hardening of the coating, removing the non-fixed portion of the solid pigment dye (2) from the surface (1).

Abstract: There is disclosed a device for dispensing liquids, in particular dyes or inks. The device comprises a liquid tank, a dispensing nozzle, and a liquid conduit with an end connected to the liquid tank for supplying liquid from the liquid tank to the dispensing nozzle. The device is provided with vibrator means, particularly a piezoelectric transducer. The transducer is used for inducing a vibrating action of the dispensing nozzle, and by the vibrating action resulting in an acceleration of the nozzle, to an extent that is sufficient to cause the detachment of the liquid from the nozzle, The invention also relates to a printing head and system utilising the inventive dispensing device.
