A machine to automatically dispense at least one fluid product, in particular a liquid dye, comprising support members configured to support one or more dispensing units each having a tank, in which said fluid product to be dispensed is contained, a dispensing nozzle and a pumping member, configured to selectively convey a desired quantity of the fluid product from the tank to the dispensing nozzle and from the latter to an external container. Rapid attachment means, drivable by an actuation element, which can also be possibly driven manually, are present to allow the easy and simple positioning of each dispensing unit on the support means and the equally easy and simple removal of each dispensing unit from the support members.

A hose-end spreader device includes a hopper configured to contain an amount of granular product, the hopper comprising a hopper inlet and a hopper outlet in communication with the hopper inlet. The device further includes a first chamber in communication with the hopper outlet, the first chamber comprising a first opening through which the granular product exits the device, and a first impeller disposed in the first chamber. Also included are a housing disposed below the first chamber, the housing comprising a fluid inlet, a second chamber in communication with the fluid inlet, and a second opening in communication with the second chamber through which a fluid exits the device, and a second impeller disposed in the second chamber. The second impeller is coupled to the first impeller.

A system and method for delivering materials for deposition is described. The system includes reservoirs for holding materials, heating elements for liquefying the materials (unless they are to be delivered as solids). Once in a desired state, pressure and material delivery systems to move the materials to a deposition nozzle. In the deposition nozzle, or thereabouts, the materials combine and are prepared to be deposited. An agitation element is used to break up the material and push it out of the nozzle tip in an atomized or droplet form. Changes in the material composition/concentration result in adjustment in heat, pressure or deposition agitation.

An automated mobile paint robot, according to particular embodiments, comprises: (1) a wheeled base; (2) at least one paint sprayer; (3) at least one pump; (4) a vision system; (5) a GPS navigation system; and (5) a computer controller configured to: (A) generate a room painting plan using one or more inputs from the GPS navigation system, vision system, etc.; (B) control movement of the automated mobile paint robot across a support surface: (C) use the vision system to position the wheeled base in a suitable position from which to paint a desired area using the at least one paint sprayer; and (D) use the at least one pump to activate the at least one paint sprayer to paint a swath (e.g., swatch) of paint from the suitable position.

The present invention, in some embodiments thereof, relates to a spreader for spreading paste (for example a tile adhesive) over a surface and more particularly, but not exclusively, to a system for pumping and uneven spreading of adhesive along a surface of a building. For example, the system may include a source of the paste optionally including a mixer, driver and/or conveyer. The paste may be driven to a spreader. For example, the spreader may deposit the paste unevenly over a surface. For example, the spreader may include multiple outlets and/or an uneven spreading blade (for example in the form of a comb). For example, the paste may be spread as lines across the surface.

A portable water batching system for mixing fireproofing coatings. A controller allows the user to pre-set the volume of a batch of water to be dispensed into the mixer for the fireproofing coating. The water batching system can also be used in conjunction with an acid/activator injection system that allows an acid solution to be introduced to the fireproofing coating slurry prior to reaching the spray gun used for application. The water batching system and acid injection system can be used in tandem with a system that proportionally controls the amount of acid solution pumped from the acid injection system to the amount of fluid pumped from the water batching system. The systems can each be equipped with data sensors to allow for recording of information for each batch of fireproofing coating.

An in-line spraying system via ultrasound, which can be used in the dispensing of agrochemical agents for post-harvest fruit, which has a spray chamber formed by a closed tank containing the liquid to be sprayed, an agitator, two ultrasound transducers and a fan; a chamber for applying the mist to the fruit, formed by a closed chamber disposed on the processing line, which has gates with slats for allowing the fruit in and out, a cylindrical applicator for the agrochemical, which is connected to the spray chamber via a duct; and a chamber for recovering the mist, formed by a closed tank coupled to the application chamber, below the Processing line, which is connected to the spray chamber via a duct, and wherein the recovered mist is moved by the fan. A process for operating the system is also disclosed.
