Abstract: A delivery device for fluid products including a plurality of containers, to contain a predetermined fluid and connected to an associated delivery unit provided with a piston unit. The device also includes a support on which the containers are mounted. The support rotates to position sequentially, at different moments of time according to one or more predetermined sequences, at least some of the delivery units in a predetermined delivery seating, to deliver corresponding quantities of fluid to obtain a desired fluid composition. Each delivery unit is provided with at least a disk type delivery valve, able to be activated between at least two distinct open conditions and a closed condition.

Abstract: A delivery device for fluid products including a plurality of containers, each able to contain a predetermined fluid and connected to an associated delivery unit. The device also includes a support on which the containers are mounted, able to rotate to position sequentially, at different moments of time according to one or more predetermined sequences, at least some of the delivery units in a predetermined delivery seating, to deliver corresponding quantities of fluid to obtain a desired fluid composition. The delivery device contains stirrers, associated with the containers to mix the fluids contained in the containers. At least some of the stirrers are able to be selectively activated, independently of each other, to maintain the corresponding fluid in optimum conditions to allow an efficient delivery by the corresponding delivery unit disposed in the delivery seating.

Abstract: A highly reflective coating painting product, particularly suitable as a coating for integrating spheres, comprises a diffusely reflective product such as, for example, barium sulphate, and an acrylic binder or glue, which are dispersed in a liquid vehicle, preferably constituted by a mixture of water and alcohol. The acrylic binder or glue is a product based on acrylic polymer or copolymer the quantity of which in the coating product is between about 1% and 15%, and preferably between 3% and 4%, by weight, relative to the reflective product. The coating product is applied to a surface in successive layers until a thickness of at least 0.5 mm is reached. The surface coated with the product is then subjected to heating, preferably at about 100° C., for about 1 hour.
