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.

An agricultural product delivery applicator for delivering particulate product to a field. The applicator includes a supply compartment to hold the product, a pneumatic conveying system, a metering system, and a controller. The pneumatic conveying system includes first delivery line operably connected to an airflow source and to the supply compartment, and a second delivery line operably connected to the airflow source and to the supply compartment. The metering system includes a first metering device associated with the first delivery line and a second metering device associate with the second delivery line. The controller controls the air flow source, the first metering device to meter product to result in a first mixed flow of airflow and product for the first delivery line, and the second metering device to meter product with the airflow to result in a second mixed flow of airflow and product for the second delivery line.

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 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.

An air amplifier utilizes a high-pressure input stream of air to accelerate a low-velocity input stream of air to provide a high-velocity, high-volume output stream of air. A coupled air amplifier array includes multiple air amplifiers which couple their respective output streams of air to one another to form a single collective output stream of air. Multiple coupled air amplifier arrays can be utilized to form coupled air amplifier array systems to provide multiple collective output streams of air which can be focused toward to an audience within a venue. The coupled air amplifier array system can be implemented within atmospheric effects systems to provide atmospheric effects, such as wind, scent, and/or temperature to provide some examples, relating to an event. These atmospheric effects systems can present these atmospheric effects to the audience to enhance the immersion of the audience as they are viewing the event. These atmospheric effects systems can include multiple portable mobile effects pods that are situated within different locations within the venue to present these atmospheric effects to different locations with the venue.
