A dispensing system for a rotary dispensing machine includes a tank, a fill tube, and a piston that moves along the fill tube and defines an air chamber and a fluid chamber within the tank. The tank is rotatable relative to the fill tube. A fluid is dispensed from the fluid chamber of the tank through at least one outlet formed in the tank.

A conveying device for conveying a viscous material from a container includes a follower plate that can be inserted into the container, and a pump by means of which the viscous material can be conveyed through the follower plate. Moreover, a measuring chamber for accommodation of a measuring sample of the viscous material is provided. The measuring chamber includes a closable material inlet opening for this purpose. A closable disposal line leads away from the measuring chamber. Moreover, a closable material return line extends from the measuring chamber via the follower plate into the container. The conveying device also includes a controller that is designed and can be operated appropriately such that it determines the compressibility of each of multiple measuring samples. The controller opens the disposal line or the material return line to the measuring sample present in the measuring chamber as a function of the compressibility thus determined.

An application device for coating components with a coating agent includes: a print head having several individual nozzles for discharging the coating agent; and a nozzle valve attached to each individual nozzle, each nozzle valve being openable for a valve opening time to discharge the coating agent from the respective nozzle. Each nozzle valve is assigned in each case a nozzle valve supply line, which nozzle valve supply line, at an outlet opening thereof, supplies the coating agent to the respective nozzle valve. Each nozzle valve supply line has an inlet opening to be closed or shut off such that a quantity of the coating agent that is metered in a defined manner or a volume of the coating agent that is metered in a defined manner is receivable in a closed off manner within the nozzle valve supply line.

The present invention provides fluid storage and dispensing tanks and methods for storing reactive fluids, such as component fluids for two-component adhesives, foams, and sealants. The tanks contain a reactive fluid for storage until the fluid is desired to be dispensed. The tank includes a subject fluid storage chamber that contains the subject fluid independent of any propellants or other fluids or gases. When the tank is desired to be used, a propellant, such as a volatile propellant or a compressed gas (e.g. compressed air) are introduced directly into or around the storage chamber to facilitate dispensing the subject fluid from the tank. The tank may include a propellant storage chamber inside the canister body and adjacent to the subject fluid storage chamber. The propellant chamber is selectively punctured when the tank is to be used. The tank may include a flexible bladder defining the storage chamber.

The invention relates to a method for producing a guiding rod for a pump for dispensing a fluid product. The rod includes a cylindrical body surmounted by a head. The method a plastic injection molding step to form the cylindrical rod. The method also includes a step of correcting the shape of an upper end of the rod so as to form the head by creating a shoulder at the level of the junction between the head of rod and body.

A cartridge acting as a dispenser for liquid treatments of a human or animal body is U shaped or hoop shape. The cartridge has a container containing a liquid treatment which when required to be dispensed is ejected through one or more nozzles projecting through the wall of the cartridge into the centre of the U or of the hoop. A base is provided for cartridges, the base controlling timing and quantity of treatments.

An unmanned aerial vehicle (UAV) includes a sprayer configured to generate a pressurized fluid flow and a nozzle configured to receive the pressurized fluid from the sprayer and to generate a spray fan to apply the fluid to a surface. The UAV includes sensors and a control unit to control both flight of the UAV and spraying by the sprayer. The fluid can be stored onboard the UAV in a reservoir or can be remotely stored and pumped to the UAV. The UAV control unit can be preloaded with a spray plan and a flight plan, or the UAV can be controlled by a user.

The invention is intended for the organization of an automated process for spraying of liquid means of chemical treatment from unmanned vehicles, for example, in precise farming systems. The use of a replaceable, marked and hermetically sealed liquid subsystem in the spray device of the invention, along with an integrated self-diagnosis system, using compressed gas energy and a pressure regulator instead of standard pumps, reduces the weight of the spraying device, improves spraying accuracy, ensures personnel safety and accounting of the accumulated life resource of the main units of spraying devices. All this in combination enables to create fully automated spraying systems.

An electronic device includes a mouthpiece, a bladder, and a mesh assembly having a mesh material and a piezoelectric material. The mesh material is in contact with a liquid of the bladder. The mouthpiece, the bladder, and the mesh assembly are located in-line along a longitudinal axis of the device between opposite longitudinal ends of the device, with the mesh assembly extending between and separating the mouthpiece and the bladder. A liquid-filled cartridge also is disclosed for use with an electronic device for delivery of a substance into a body through respiration includes a liquid container; and a liquid contained within the container for aerosolizing and inhaling by a person using the electronic device. The liquid includes a plurality of nanoparticles in a nanoemulsion, the nanoparticles including the encapsulation of the substance to be delivered into the body through respiration. The nanoemulsion preferably is produced using a microfluidizing machine.
