Abstract: A stirrer lid for color cans on stirring machines, of the type having at a base thereof a frustoconical closure edge, having a main body (5), and including an annular ring (7) fastened to the base of the body and of being downward tapering frustoconical cross section with the ring (7) forming the closure edge of the lid.

Abstract: A lid which is provided with a variable-flow pouring spout and with an improved vent device, particularly for cans of base color for automobile coachwork. The lid includes a vent opening which is provided on an inner face thereof with a channel which leads out at a point close to the edge of the lid, substantially diametrically opposite the pouring spout.

Abstract: The invention relates to a lid upon which a vessel can be fixed. The lid comprises a pouring spout optionally equipped with a valve device and a handle capable of including control means for said valve device. The lid comprises, moreover, means permitting its mutual fitting upon a support element, a position in which it carries said vessel. The lid according to the invention is especially adapted to be employed in a mixing machine used for the homogenization of a product mixture.

Abstract: An apparatus is provided for locating the level of liquids for particular use in volumetric dosage techniques. A probe is mounted upon a vertical column which slides axially in a slide fixed in the housing of the apparatus. Adjacent to the slide is a threaded rod rotatably mounted in the housing and a releasable nut which is integral with the vertical column and the threaded rod. The releasable nut permits engagement and disengagement of the vertical column and threaded rod. A drive mechanism connected to the vertical column is employed to control a potentiometer as a function of the position of the vertical column.

Abstract: A mixer for use in combination with a vessel having a detachable lid is provided which comprises a helical blade rotatably mounted upon a vertical shaft pivoting at its upper end within a bearing member disposed within the lid of said vessel, said helical blade providing a vertical mixing, and means for imparting a vibratory motion of low vertical amplitude to said blade, said vibratory movement being generated from the rotating motion of the mixer shaft.
