Furthermore, it comprises a spattering material supply, a storage with desired spattering data, which is predefined and comprised in a digital image or CAD-model memorized on the storage, a spatial referencing unit, to reference the spattering device relative to the target surface and a computation means to automatically control the expelling by the nozzle control mechanism according to information gained by the spatial referencing unit and according to the desired spattering data is evaluated and adjusted by changing the characteristics of expelling of the nozzle means in such a way that the target surface is spattered according to the desired spattering data.

The present invention relates to a method and apparatus for delivering droplets of fluids onto an open tray containing poultry, the tray being stationary. According to the invention, the method comprises the following steps: (a) a movable arm is moved over the tray in translation in a first direction, said arm supporting a first set of dispensing nozzles and a second set of dispensing nozzles, said nozzles of each set being arranged to cover the entire dimension of the tray in a second direction perpendicular to the first direction; (b) initially, droplets of at least one first fluid are dispensed by spraying using the first set of dispensing nozzles; (c) and then at least one second fluid, distinct from said at least one first fluid to be sprayed, is dispensed by ejecting individual drops by means of the second set of dispensing nozzles.

A plural component dispensing system individually delivers separate material components to each of a plurality of proportioners. Each of the proportioners regulates volumetric flow of each of the separate material components to produce a target ratio of the separate material components associated with the proportioner. The target ratios associated with the plurality of proportioners can be the same or different target ratios. Each proportioner delivers the separate material components at the associated target ratio to one of a plurality of dispensing devices. Each dispensing device mixes the separate components received at the corresponding target ratio and delivers the components as a mixture.

The present disclosure relates to a dispensing device for an agricultural sprayer. The dispensing device includes a supply manifold having at least two inlets, each inlet connectable to a product source and engaging with a closing valve, and a dispensing manifold having at least two outlets, each outlet connectable to at least one spraying member and engages with a closing valve. The dispensing device further includes a control mechanism that includes at least one camshaft having a plurality of cams. Each cam controls the opening and closing of an associated valve.

An object is to provide a spray coating device and a coating method, with which a uniform coating film can be formed by spray coating with two liquids having reactivity, and in which precipitation of a reaction product on a periphery can also be prevented. The object is achieved by providing a transporting unit for transporting a substrate downward; a first spray nozzle; a second spray nozzle disposed below the first spray nozzle; a holding plate for holding the first spray nozzle and the second spray nozzle such that an angle formed by center lines of the first spray nozzle and the second spray nozzle is 5° to 150°; and a liquid film forming unit for forming a liquid film which flows from above to below on a surface of the holding plate.

Disclosed herein is an apparatus for dispensing a mixture of at least two liquid components. The apparatus may comprise an A liquid component source fluidly connected with an A liquid component pump driven by a first motor; and a B liquid component source fluidly connected with a B liquid component pump driven by the first motor. Each of the A liquid component pump and the B liquid component pump may comprise at least two chambers. The A liquid component pump and the B liquid component pump may be fluidly connected with a dispenser unit. There may be one or more A liquid temperature regulators between the A liquid component pump and the dispenser unit. Similarly, there may be one or more B liquid temperature regulators between the B liquid component pump and the dispenser unit.

A system for applying a coating composition is provided herein. The system includes a first high transfer efficiency applicator defining a first nozzle orifice and a second high transfer efficiency applicator defining a second nozzle orifice. The system further includes a reservoir. The system further includes a substrate defining a first target area and a second target area. The first high transfer efficiency applicator and the second high transfer efficiency applicator are configured to receive the coating composition from the reservoir and configured to expel the coating composition through the first nozzle orifice to the first target area of the substrate and to expel the coating composition through the second nozzle orifice to the second target area of the substrate.

A quantitative essential oil dripping device which includes: N sealed essential oil containers for containing essential oil, wherein N is a positive integer greater than or equal to 1; N gas inlet tubes and N oil outlet tubes, which are all inserted into the N essential oil containers respectively, wherein in each of the essential oil containers, a gas outlet of the gas inlet tube is located above an inlet of the oil outlet tube; a gas pump arranged at gas inlets of the N gas inlet tubes; a throttle valve communicating the gas pump with the essential oil container; and a drip number detection module configured to detect the drip number of the essential oil dripped from an oil outlet of the oil outlet tube. During use, the gas pump is started, pressure is applied to the essential oil container through the gas pump, and the essential oil is driven to be dripped from the oil outlet tube under the combined action of the gas pump and the throttle valve, thereby achieving the dripping of the essential oil. The drip number of the essential oil dripped from the oil outlet of the oil outlet tube is detected through the drip number detection module, and the amount of the dripped essential oil is measured by recording the drip number, thereby accurately controlling the dripping of the essential oil. After the dripping of the essential oil is completed, the gas pump is stopped.

A coating system for coating objects having an application device and a supply system which supplies the application device with a liquid material. The supply system includes at least one base supply device with a piggable supply line which extends between a first pigging station and a second pigging station and can be connected to one of multiple material sources by a supply unit. The piggable supply line is a piggable primary supply line which can be connected to a discharge line of the supply unit by a valve unit. A piggable secondary supply line is provided which is connected to the valve unit and is connected to a secondary pigging station at the end remote from the valve unit. The valve unit is designed as a multi-way valve such that the discharge line of the supply unit can be at least selectively connected to the primary supply line (68.1); or the discharge line of the supply unit can be at least selectively connected to the primary supply line and the secondary supply line; or the primary supply line can be at least selectively connected to the secondary supply line.
