Systems and methods are disclosed that include a spraying apparatus having a hand held spraying device, a flexible reservoir connected in fluid communication with the hand held spraying device and worn on the body of a user of the spraying apparatus, and a pressure device that provides pressure to the flexible reservoir to move fluid from the flexible reservoir to the hand held spraying device.

A dispenser used for discharging a mixture of gas and a paste material includes: a nozzle part provided in a tip end part of a body and having a tip end opening through which the mixture is discharged; a flow path extending from a mixture introduction part to the tip end opening through a hollow space of the nozzle part; a needle part movable in the flow path of the nozzle part to open and close the flow path; a driving part that drives the needle part; and a stopper part 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 decreases toward the tip end opening. Also provided is a stopper position adjusting part that adjusts a stop position defined by the stopper part.

A spray gun, in particular a pressurised air atomisation paint spray gun, in particular a hand-held pressurised air atomisation paint spray gun has at least one material nozzle for discharging a material to be sprayed, at least one air nozzle for outputting air, in particular air for atomising a material to be sprayed, air for changing the shape of a spray jet, and/or air for transporting an atomised spraying medium, and at least one air chamber, in particular an air chamber adjoining the air nozzle or at least one air outlet opening of the air nozzle in the upstream direction, for supplying the air nozzle with air. The spray gun also has at least one device for inputting and/or adjusting and/or detecting and/or determining and/or displaying the air pressure in the air chamber during operation of the spray gun.

Embodiments of the disclosure relate to automated water sprinkler systems, and more particularly to programmable electronically controlled sprinkler systems which are controllable to affect sprinkler direction and time of watering over a defined coverage pattern. The particular improvements disclosed herein relate to location awareness of the system based on physical location of the unit relative to one or more base platforms, as well as gesture/motion control of the unit for manual operation through the use of an on-board accelerometer.

Provided is an adapter for connection to a spray can dispensing an oil-containing aerosol. The adapter comprises a timepiece configured to measure a predetermined time interval, the starting point of the time measurement being defined by the start of a spraying process of the spray can; and an indicating element configured to indicate to the user, once the predetermined time interval has expired, to end the spraying process. Also provided is a method for manually reprocessing a medical device.

A system for controlling nozzle flow rate includes a master node having an expected overall flow rate module configured to generate an expected overall flow rate of an agricultural product based on one or more sprayer characteristics, and an adjustment module configured to generate an error correction based on a difference between the expected overall flow rate and an actual overall flow rate of the agricultural product. A plurality of smart nozzles are in communication with the master node, each of the smart nozzles includes an electronic control unit in communication with one or more control valves and one or more nozzle assemblies. Each of the smart nozzles includes a target smart nozzle flow rate module configured to generate a target smart nozzle flow rate of the agricultural product based on the one or more sprayer characteristics. The target smart nozzle flow rate is adjusted according to the error correction.

A spray assembly for a working machine that includes a fluid storage tank includes a plurality of nozzle assemblies, each of which includes a direct acting valve. The spray assembly also includes a controller that is operatively connected to each of the direct acting valves for controlling the opening and closing of the direct acting valves, and a selector that is operatively connected to the controller. The selector may be employed by an operator of the working machine to selectively operate one or more of the direct acting valves in order to provide a desired spray pattern of fluid from the fluid storage tank.

A paint gun for atomizing (in particular by way of compressed-air-assisted atomization) and applying a coating material such as a paint has a material-guiding part, a non-material-guiding part, and a transmitting and/or receiving device for wireless signal transmission. In order to increase the functional reliability and provide optimal operability in the environment in which the coating material is applied, the transmitting and/or receiving device for wireless signal transmission is arranged at a distance from the material-guiding part and is associated with the non-material-guiding part. Alternatively or additionally, an increased functional reliability is achieved by designing the transmitting and/or receiving device for wireless signal transmission in accordance with two different radio standards. Furthermore, a material application system comprising such a paint gun as well as a method for operating same are described.

Removable and replaceable outlets for point-of-use showers or faucets, filter devices, and methods and systems including the outlets and/or filter devices, are disclosed.

A spray gun for a high-pressure cleaning appliance is provided, with a gun casing, in which is arranged a valve, which has a through duct which extends from a valve inlet to a valve outlet, and has a closure body which, in a closed position, bears in a fluid-tight manner against a valve seat and which is adapted to be moved, with the aid of a hand lever mechanically coupled to the closure body, into an open position spaced apart from the valve seat, and with an electric apparatus which has an electric display device and at least one battery. The electric apparatus has an electric casing which is sealed against sprayed water and forms a sub-unit adapted to be handled independently, wherein all of the current-carrying components of the spray gun are arranged in the electric casing and are separated galvanically from the remaining components of the spray gun.
