A substrate processing apparatus includes a fluid supply unit that supplies a fluid that includes a pressurized vapor or mist of a purified water, a processing liquid supply unit that supplies a processing liquid that includes at least sulfuric acid, and a nozzle that includes a first discharge port that discharges a fluid that is supplied from the fluid supply unit, a second discharge port that discharges a processing liquid that is supplied from the processing liquid supply unit, and a guiding route that is communicated with the first discharge port and the second discharge port and guides a mixed fluid of a fluid that is discharged from the first discharge port and a processing liquid that is discharged from the second discharge port, where a cross-sectional area of the guiding route is greater than a cross-sectional area of the first discharge port.

A snow making apparatus includes a cylindrical body and a snow making nozzle that jets water droplets into the cylindrical body. The cylindrical body has a proximal end that is opened to a temperature environment where snow can be produced from water droplets jetted from the snow making nozzle. A distal end of the cylindrical body is connected to a pipe member communicating with a test chamber. The snow making nozzle is formed of a two-fluid nozzle. The pipe member communicates with a snowfall hood disposed in the test chamber and having a supply opening that allows snow to fall. The cylindrical body is disposed in an oblique posture so as to be lowered from a proximal end toward a distal end of the cylindrical body.

A cleaning nozzle for cleaning a fueling receptacle capable of receiving a separate fueling nozzle for transferring cryogenic fluid from a fueling station is disclosed. An example cleaning nozzle includes a body that defines a cavity. The example cleaning nozzle includes a nozzle head coupled to and extending from a distal end of the body. The nozzle head defines a plurality of spray holes to spray pressurized air onto the fueling receptacle. The example cleaning nozzle includes a blower that defines a blower inlet, a blower outlet, and a blower flow path extending between the blower inlet and the blower outlet. The blower comprises a valve and a lever operatively coupled to the valve. The example cleaning nozzle includes an insert defining an insert flow path that is fluidly coupled to the blower outlet. The example cleaning nozzle includes a connector fluidly connecting the insert and the nozzle head.

A bidet washing apparatus attachable to a toilet howl for cleaning one or more body parts of a user includes a water inlet, a control unit, a control unit switch, and a control unit outlet; a reservoir dispenser having a chamber, a reservoir dispenser switch, a reservoir dispenser valve, a reservoir dispenser outlet, and one or more lids or caps having a built-in check valve on the one or more reservoir dispensers; a nozzle assembly having a washing nozzle, connected to the control unit outlet with a water tube, a protective shield gate covering the nozzle assembly and washing nozzle; and a plurality of nozzle assembly connected to the reservoir dispenser outlet with a water tube tor cleaning and/or disinfecting the nozzle assembly, washing nozzle, and/or the protective gate.

A coating system operations vehicle. Related methods are provided for filling a tank and operating coating equipment on a vehicle. The methods include pumping coating from containers into a tank on the vehicle and dispensing the coating for application on a surface. A method also includes removing residual coating from the containers after pumping out coating and adding the residual coating material to the tank. If the level of coating is at the desired level in the tank, a layer of water may be formed over the coating in the tank.

Disclosed is an surface-coating robot operating system, a movable base (100) is provided to drive the whole operating system to implement autonomous navigation movement in the workspace; a vertical linear actuator (200) is used to drive a mechanical arm (300) to move up and down so as to meet the requirement for spraying at different heights; and the mechanical arm (300) is used to drive a spray gun (400) to implement multi-degree-of-freedom motion so as to meet the requirement for spraying at different positions; the whole spraying process is autonomously completed by the operating system, which is time-saving and labor-saving, high efficient, and ensures uniform spraying thickness, smooth spraying surface and consistent spraying quality; the robotic spraying may obviously reduce the coating dusts generated in a spraying process and the human risk caused by exposure to harmful coating chemicals. An operating method for surface-coating robot is disclosed.

A cyclonic valve for cleaning pumps for transferring powders of any type in high density, including an inlet duct for introducing a flow of cleaning fluid, a flow dividing element adapted for dividing the flow in inlet into a plurality of flows, and a flow orienter having means for deviating and orienting in space the plurality of flows so as to give each of the flows a tangential motion component with respect to the direction of the flows, and then conveying the flows into one or more ducts towards the device to be cleaned, so as to generate a single cleaning flow in outlet having helical motion.

The disclosure relates to a rotary atomizer for applying a spray jet of a coating agent (e.g. paint) to a component (e.g. motor vehicle body component). The disclosure provides that the construction dimensions of the rotary atomizer are coordinated in such a way that the air pressure at the outlet opening of the paint nozzle during operation is lower than the air pressure in the nozzle chamber of the bell cup and in the external rinsing channels in order to prevent a backflow of the coating agent from the outlet opening of the paint nozzle backwards in the direction of the nozzle chamber due to the pressure difference.
