A liquid spray system (100) comprises a housing (110), a spray applicator (120) and an air pressurising device (130). The housing (110) comprises a retaining section (140) to receive a receptacle (200), the receptacle (200) comprising a flexible body (201, 202) having a reservoir (204) comprising a liquid for spraying, and a liquid outlet (205) in fluid communication with the reservoir (204). The retaining section (140) also comprises a receptacle compressor (170) configured to apply a compressive force to the flexible body (201, 202) to force liquid from the liquid outlet (205) of the receptacle (200). The spray applicator (120) is disposed remotely from the housing and in fluid communication with the liquid outlet of the receptacle (200). The air pressurising device (130) is in fluid communication with the spray applicator (120) to propel the liquid from the spray applicator (120).

In a cleaning method for removing adhesive residues from surfaces, in particular after separating an adhesive connection between adhesively joined partners, liquid carbon dioxide from a reservoir enters a jet, apparatus and is guided there through a first dosing unit into an expansion chamber wherein a cold-resistant liquid is then supplied to a mixture created in the expansion chamber from gaseous carbon dioxide and carbon dioxide particles and wherein the mixture, to which the cold-resistant liquid has been added, exits the jet apparatus via an outlet opening thereof. Furthermore, a jet apparatus removes adhesive residues from surfaces.

A spray nozzle, systems and methods for cleaning at least one optical fiber end face of an optical fiber connector. The nozzle includes a housing body with a first end portion and a second end portion. A discharge passage carries an atomized mixture of cleaning fluid and positively pressurized air from the first end portion to a discharge opening at the second end portion. A vacuum return passage communicates with the discharge passage proximate the second end portion. The return passage receives the atomized mixture of cleaning fluid and positively pressurized air as well as contaminants removed from the optical fiber end face. A portion of the atomized mixture of cleaning fluid and positively pressurized air is diverted from the discharge passage to control the amount of the atomized mixture being directed at the optical fiber end face.

A liquid spray system (1e) and method of using a liquid spray system is shown. The spray system (1e) comprises a receptacle (100e) for holding liquid to be sprayed, a support structure (200e) for supporting the receptacle (100e), a spray applicator (300e) disposed remotely from the support structure (200e) and an air pressurising device for driving the liquid out of the receptacle (100e) and for mixing with the liquid at an outlet of the spray applicator (300e). Advantageously, the spray system (1e) is compact and versatile.

An atomization powder making device suitable for atomizing molten metal to produce powder includes a housing defining an atomizing chamber, a vessel mounted inside the housing and defining a receiving space for receiving the molten metal, and a flow guide unit extending from the bottom of the vessel and having at least one liquid flow channel for conveying the molten metal from the receiving space to the atomizing chamber. A push unit is disposed in the receiving space for pushing the molten metal to flow through the at least one liquid flow channel. A gas supply unit is configured to supply an atomizing gas for atomizing the molten metal flowing out of the liquid flow channel.

A system having a material sensor system coupled to a material tank is provided. The material tank is configured to receive a quantity of the material and output a flow of the material. The material sensor system includes a float system coupled to an inner surface of the material tank. The float system includes a float configured float within a float cavity. The material sensor system includes a switch coupled to an outer surface of the material tank. The switch is communicatively coupled to the float system through a wall of the material tank, and the switch is configured to send one or more signals to a control system when the float engages the switch.

A twin-fluid atomized aerial spray system and method of aerial spraying includes flying an atomized spray delivery system with an unmanned aerial system. The atomized spray delivery system includes a first fluid delivery path, a second fluid delivery path and a spray nozzle. The first fluid delivery path has a liquid tank and the second fluid delivery path has a compressed gas tank, wherein the first and second fluid delivery paths deliver respective fluids to the spray nozzle. Liquid from the liquid tank is atomized with compressed gas from the compressed gas tank at the spray nozzle and delivers the atomized spray from the spray nozzle.

An arrangement introduced into a motorized nebulizer equipped with a pneumatic nozzle for generating cold drops, which allows for the high efficiency of the application through the formation of a droplet spectrum within the range of sizes recommended by the World Health Organization (WHO) for the control of insects, in particular, mosquito vectors of human diseases, in flight, which is a spectrum with a median volumetric diameter (MVD) of less than 30 microns (μm).

Some embodiments of the invention belongs to a technical field of NdFeB magnet processing, and mainly relates to a device and method for improving the coercivity of ring-shaped NdFeB magnet. A layer of heavy rare earth coating is sprayed on the inner and outer surfaces of the ring-shaped NdFeB magnet by the device, and then the ring-shaped NdFeB magnet sprayed with the heavy rare-earth coating is subjected to diffusion treatment to improve the coercivity of the ring-shaped NdFeB magnet. The invention uses heavy rare earth slurry as the diffusion source, combined with spraying technology, can quickly and uniformly cover a layer of heavy rare earth coating on the inner and outer surfaces of the ring-shaped NdFeB magnet, and the coercivity of the ring-shaped NdFeB magnet is improved after heat treatment.

The present invention concerns the provision of a novel glue application apparatus for controllably depositing glue on the mating surfaces of door components in a manner that provides adequate glue coverage while preventing the deposition of excessive amounts of glue. The glue application apparatus includes multiple glue dispensers having uniquely configured glue dispensing nozzles that are uniquely positioned at various angles to accommodate mating surfaces of different profiles.
