A device for dispensing a fluid topical composition includes a reservoir storing the composition and dispensing a pressurized flow of the composition. The device also includes an accumulator having an expandable chamber in fluidly communication with the reservoir. The chamber is biased towards a deflated configuration so that, when filled with the composition the chamber expands against this bias applying pressure to the composition stored therein. The device includes a supply valve regulating the flow of the composition from the reservoir to the accumulator, and a pressure sensor. The device further includes a processing arrangement analyzing data from the sensor to determine whether pressure in the accumulator is above a predetermined threshold and controlling the supply valve to maintain the pressure within a desired pressure range. The device also includes a deposition arrangement dispensing the composition from the accumulator under control of the processing arrangement.

A pressure regulator for use in an elbow connector for use with a sprinkler assembly including a pressure responsive member, movably mounted in the elbow connector and movable from an open position allowing flow of water into the sprinkler assembly and a closed position where the bottom edge of the pressure responsive member blocks the flow of water into the sprinkler assembly. The pressure responsive member is biased in the open position and moves into the closed position when downstream water pressure exceeds a predetermined value.

A dispenser for discharging a mixture of gas and paste material includes: a nozzle part (2) provided in a tip end part of a body (11) and having a tip end opening; a flow path (4) for the mixture extending from an introduction part (5) for the mixture to the tip end opening through a hollow space of the nozzle part; a needle part (3) movable in the flow path of the nozzle part to open and close the flow path; a driving part (7, 8, and 9) that drives the needle part; and a stopper part (10, 14, and 16) that limits an operation range of the needle part. The nozzle part has a tapered section in which an inside diameter of the flow path of the nozzle part relative to an operation range of a tip end of the needle part decreases toward the tip end opening.

There is provided a holding member including: a holding unit configured to hold a package with a variable volume; and a connection unit configured to connect the holding unit and an unmanned aerial vehicle. The holding member may include a posture change unit configured to change a posture of the holding member, and a posture fixing unit for the holding unit. The holding member may include a package fixing unit configured to fix the package to the holding unit. There is provided a spraying method in which in a state in which the holding member holds the package, and the holding member holding the package is mounted on the unmanned aerial vehicle, a content of the package is sprayed from the unmanned aerial vehicle.

A system for analysing drops capable of being ejected by a coating product applicator, includes a light source configured to illuminate a drop ejection zone, designated observation zone; a first image acquisition device configured to acquire an image of the observation zone; and an image analyser configured to determine, from the image of the observation zone, the presence of drops at a given distance from the applicator, the size of the drops and the absence of satellite; the light source and the first image acquisition device being situated on a same side of the observation zone.

Embodiments of lab automation workstations are disclosed in which the pod that performs pipetting operations is integrated with pipette tip-loading functionality. To generate the necessary tip-loading force, a dual drive system is used that is symmetric about the Y-axis to allow for offset or partial tip box loads by dynamically centering the drive force (e.g., the tip-loading force) over the reaction load. This minimizes the need for oversized linear motion components while still allowing for the generation of high tip-loading forces needed to properly load a large number of pipette tips simultaneously.

Controlling application of adhesive on a substrate includes using a gas sensor, obtaining a first sensor signal. The first sensor signal indicates a partial pressure of a gas that arises from a constituent of the adhesive. Based at least in part on this partial pressure, the controller either controls an applicator's delivery of the adhesive to a substrate or causes an error signal indicative of the adhesive's unsuitability for adhesion.

An atomizing spray nozzle device includes an atomizing zone housing that receives different phases of materials used to form a coating. The atomizing zone housing mixes the different phases of the materials into a two-phase mixture of ceramic-liquid droplets in a carrier gas. The device also includes a plenum housing fluidly coupled with the atomizing housing and extending from the atomizing housing to a delivery end. The plenum housing includes an interior plenum that receives the two-phase mixture of ceramic-liquid droplets in the carrier gas from the atomizing zone housing. The device also includes one or more delivery nozzles fluidly coupled with the plenum chamber. The delivery nozzles provide outlets from which the two-phase mixture of ceramic-liquid droplets in the carrier gas is delivered onto one or more surfaces of a target object as the coating on the target object.

A paint distribution system comprising a circulating pump configured to supply pressure to the system, in which the circulating pump has an input, configured to receive input data signals; a measuring device for measuring one or more parameters of a paint, in which the measuring device has an input, configured to receive input data signals, and has an output, configured to transmit output data signals, and in which the measuring device is positioned on a paint supply line in fluid communication with a paint color change assembly; and a controller having an input, configured to receive input data signals, and an output, configured to transmit output data signals. The output data signals from the controller are transmitted to the circulating pump to maintain or adjust circulating pump settings to control supply pressure to the system and maintain or adjust the parameters of the paint within a predetermined range.

A novel sprinkler system designed to take into account the effect of wind on water droplets. There is also disclosed a wind shifting algorithm which, when used, corrects the sprinkler water spray to counteract the effect of wind, such that good water coverage and precipitation uniformity can be achieved.
