The invention relates to a method for determining suitable spreading settings for an agricultural spreading machine (10) for achieving an intended spreading material distribution of a spreading material (30) across an agricultural area (12), comprising the steps of: determining the current ejection direction of the ejected spreading material (30) during a spreading operation and determining a suitable application point setting for the agricultural spreading machine (10) taking into account the determined current ejection direction of the ejected spreading material (30) and an ejection direction for the ejected spreading material (30) which is suitable for achieving the intended spreading material distribution during the spreading operation.

A sealant discharging nozzle includes a nozzle body, a flat surface, a cutout, and a shaping portion. The flat surface is provided on the nozzle body and is formed on a discharge port side of a through hole that extends along a central axis of the nozzle body. The cutout is formed on a first side with respect to the flat surface. The shaping portion is, with respect to the flat surface, formed on a second side opposite to the first side.

A sprayer includes: a container; a passage including a transparent window, a first opening, a second opening and a resonator, wherein when liquid in the container is passed through the resonator via the first opening, the liquid is emitted as a gas via the second opening; and a removable detection unit disposed outside of the passage. The removable detection unit includes: a light source for illuminating the gas in the passage; an optical sensor disposed to detect a parameter of light reflected by the gas; and a processor coupled to the optical sensor for stopping the resonator from generating the gas when the parameter is below a threshold. The passage further includes a cavity disposed on a bottom surface of the passage in front of the optical sensor, wherein when the gas in the passage contacts the bottom surface, resultant water vapour will enter the cavity.

With the use of low cost microphones mounted near each nozzle, sound signatures of the nozzles may be captured and compared to a baseline calibration measurement corresponding to a substantially new nozzle to determine if the nozzle is worn out. Sound signatures may be periodically captured and compared to the baseline calibration measurement to provide a continuous indicator of wear out for each nozzle. The invention has the advantage of being relatively low cost with ceramic microphones, for example, and with little or no moving parts required.

A dispensing control system, including a frame component having a first side surface and a second side surface, a first sensor portion positioned proximate the first side surface, and a second sensor portion positioned proximate the second side surface, the second sensor portion being separated from the first sensor portion a distance to allow a liquid spray stream exiting a dispenser of a conformal coating machine to pass therebetween, wherein the first sensor portion transmits a beam of light towards the second sensor portion to measure the liquid spray stream exiting the dispenser, the beam of light encompassing both edges of the liquid spray stream while the dispenser is stationary, is provided. Furthermore, an associated method is also provided.

The disclosure relates to a cleaning device for cleaning an application device which, in operation, applies at least one coating agent jet of a coating agent (e.g. paint) to a component (e.g. motor vehicle body component). The disclosure provides that a jet checking device is integrated into the cleaning device for checking the coating agent jet emitted by the application device, so that the cleaning device forms a structural unit with the jet checking device.

A method of generating a building assembly that includes spraying a coating material onto a plurality of pieces of substrate disposed on a first assembly face. The spraying includes spraying the coating material onto the plurality of pieces of substrate via a sprayer configured to apply the coating material to a target surface via a nozzle coupled with a mobile storage container storing the coating material, the coating material impregnating voids of the substrate. The method also includes allowing the coating material impregnating the voids to dry and harden and become rigid to generate the building assembly.

A method for controlling gas dynamic cold spraying, the method including providing a particle jet by using an accelerating nozzle, according to a first set of operating parameters, illuminating the particle jet with illuminating light pulses, capturing one or more images of the particle jet by using an imaging unit, and determining one or more velocity values by analyzing the captured images,
wherein the method includes providing two or more sequences of illuminating light pulses during an exposure time period of a single captured image.

By measuring a position of a spray gun relative to a physical surface to coat, using data on technical characteristics of the spray gun, like a spray cone the spray gun may produce and data on a coating fluid used, characteristics of a coating layer thus physically deposited may be reconstructed. With data being recording during the spray job, this is faster and more accurate than measuring layer thickness at various locations, either pre-determined or randomly. By determining flow characteristics in a spray cone and position of the spray cone relative to the surface over time and using a model of the spray cone, deposition of the layer of coating may be determined and the final layer, cured or uncured, may be reconstructed, including thickness.

A method and device for indicating whether a dispensable product will require refilling prior to the next scheduled service interval includes tracking the amount of use over a first interval, and calculating a frequency based from the use over the first interval. The quantity remaining is compared with the required amount, which is the product of the number of weeks in the service interval and the calculated frequency. Thus, when the quantity remaining is less that the required amount, a warning will be provided to indicate that the dispensing product should be replaced, as it will be empty before the next service interval.
