A rain simulation system that replicates realistic raindrop characteristics for controlled testing is invented. The rain simulation system can be used as a stand-alone system with wind using a blower fan or in a wind tunnel, and without wind to create wind-driven and vertically falling rain droplets, respectively. In addition, methods to simulate rainfall for stationary and moving objects such as a road passenger vehicle are proposed. The rain simulation system is fully adjustable for a range of droplet size, impact velocity, rain intensity, rain coverage via the use of dripping nozzle devices and positioning of system components. The rain simulation system dispenses distinct droplets or continuous streams that can be broken down into droplets by wind. A rain nozzle device is coupled with a rain reservoir, and multiple nozzles are used to create a rain matrix, the full matrix is integrated with a rain rack and rainwater flow control strategy.

The disclosure relates to a cosmetic product, comprising a) a cosmetic preparation, containing, in relation to its total weight, a1) about 45 to about 95 wt. % of at least one polar solvent; a2) about 0.1 to about 25 wt. % of at least one solid material; b) a device for flash evaporation of the cosmetic preparation a), and to a method using corresponding products and to the use of the cosmetic preparation a) as process material in a device for flash evaporation.

An automated mobile sprayer (AMS) includes a mobile base, an applicator arm supported by the mobile base, and a nozzle extending from the applicator arm. The nozzle receives fluid from a fluid supply and generates an atomized fluid spray for application to a surface. The applicator arm moves vertically relative to the mobile base and the surface to cause the nozzle to generate a vertical fluid stripe. The mobile base moves laterally relative to the surface to cause the nozzle to generate a horizontal fluid stripe.

A walk from behind, also called a push or cart sprayer having an assembly of wheeled frame and a tank. The frame has a rearward extending handle which enables the assembly to be pushed along a path. The tank has a connected boom assembly including a pivotal boom arm along the front of the tank with a distal spray nozzle, and a mechanism enabling the boom arm to be pivoted to the sides of the tank where the nozzle sprays away from the path, to the side of the path, so that possible toxic or corrosive spraying liquid cannot be stepped upon by the operator pushing the sprayer, thereby enhancing safety of operation. The boom arm is also pivotal to the front of the tank, such as useful when the cart sprayer is towed.

A device for spraying a liquid for use in dye penetration inspection into an inner cavity of a workpiece for making a turbine engine part, the device including a workpiece support, a manifold for spraying the inspection liquid into the inner cavity, a manifold for sucking up and discharging the sprayed inspection liquid, and a mechanism for tilting at least a portion of the support from a substantially horizontal position to an inclined position in which the workpiece is inclined so that the inspection liquid sprayed into the cavity flows under gravity to a zone from which it is sucked up.

A motion-activated dispenser includes a housing having a base and top defining a gap sized to receive a human hand. The top portion defining cavity sized to receive a fluid reservoir and an opening extending directly through a lower surface of the top portion to the cavity, a neck of the fluid reservoir extending through the opening. A pressing member is positioned within the cavity and an actuator is coupled to the pressing member and configured to urge the pressing member toward and away from the opening. The pressing member may include, for example, a sliding member positioned opposite a stop face; a roller moved by the actuator toward the opening; a plunger positioned above the opening and driven by an actuator toward the opening; or a pair of rods spanning the cavity and urged by the actuator through the cavity, the rods pressing against sides of the reservoir.

A coating apparatus for a color filter substrate, including a coating sprayer (1) configured to coat a first film layer on a color filter layer (03) formed on the color filter substrate (01); a grinding device (2) configured to grind the color filter layer (03) to eliminate a step formed by the color filter layer (03) covering a black matrix (02); and a detection control unit (3) configured to measure a height of the step, determine a grinding amount of the grinding device (2) according to the height of the step, and control an operation of the grinding device (2) such that the first film layer coated on the color filter layer (03) has a flat surface. Also disclosed is a coating method for a color filter substrate.
