A combined roof spraying and seaming assembly that is easy, safe, and efficient to operate. The assembly is able to provide consistent coating thickness to the surface of a roof, while being able to fully coat all surfaces on the roof. The assembly can readily seam various types of roof surface conditions, such as those having channeled, corrugated, and/or ribbed surfaces.

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.

The device includes a substantially L-shaped body including a docking station for mounting a wick-based fragrance dispensing bottle within a range of sizes. The docking station can include a number of resilient support tabs that grasp the neck of the bottle and serve to localize the bottle's top wick to a central plane regardless of bottle size so that it can be adjustably engaged by a movable heater. Resilient guide tabs straddling the plane are stiffer than a resilient latching tab that moves within the plane. The heater can be mounted on a sliding carriage that can move along the plane to closely nest the wick for increased vapor emission and move away to decrease vapor emission.

An effective implementation is shown for a height adjustment system for one or more spray guns used in a line striper.

A coating system (1) is provided which includes an ultrasonic sprayer (3) capable of spraying a coating fluid onto a target surface (5). A convective or infrared heater (21) is associated with the sprayer and is operable to heat the spray (23) produced by the sprayer (3).

Disclosed herein is a tool for holding a spray painting instrument, such as a painting gun for painting an internal surface of a pipe. In particular, the inventive tool is ideal for painting the interior of curves and angles in a pipe and is capable of moving through and uniformly painting up to 90 degree angles of pipes or hollow tubes. The tool has a hollow central tube for carrying a spray-painting gun and at least two projections extending outwardly from an outer surface of the hollow tube. A retracting arm assembly is provided on each projection. Each retracting arm assembly includes first and second retracting arms and a corresponding force exertion mechanism. In operation, when the tool is inserted inside the pipe, each retracting arm touches the internal surface of the pipe due to an outward force exerted thereon. The tool is movable inside the pipe and adjusts automatically to different pipe diameters. The tool can be used manually or in an automated fashion to push and pull the paint gun and paint the interior of a pipe.

A system for heating, coating, cooling and screening a granular substrate is provided. The system, such as an apparatus for continuous coating granular particles, includes a preheater apparatus for heating granular particles, a rotary drum having an inlet horizontally coupled to the preheater for receiving heated granular particles directly from the fluidized bed preheater, a coating apparatus positioned within the drum for applying a coating to the heated granular particles, and a cooling apparatus positioned horizontally in association with the drum for cooling the granular particles subsequent to coating.

A microfluidic device provided in a body accommodating a fluid containment chamber. A fluidic access channel and a drop emission channel are formed in the body and are in fluidic connection with the fluid containment chamber to form a fluidic path towards the body outside through a nozzle having an outlet section. An actuator is operatively coupled to the fluid containment chamber and is configured to cause ejection of fluid drops through the drop emission channel in an operating condition of the microfluidic device. The drop emission channel comprises a portion of reduced section having a smaller area than the outlet section of the nozzle.

A sport footwear is provided with a tank containing a pressure timed evanescence marker fluid, an opening, from which the liquid is spouted, associated with the tank and regulated by a check valve, electromechanical actuation means comprising a wireless receiving card, suitable for imposing the opening condition of the check valve and actuable by means of remote control means comprising at least one wireless network card. Between the wireless network card and the wireless receiving card a wireless type connection is established, suitable for connecting the control means with the actuation means and for setting the opening condition in the check valve in order to achieve the pressure liquid to be spouted from the opening of the footwear.
