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.

Abstract: Apparatus for dividing a segment of variable length into equal parts employing any whole number as a divisor. The apparatus comprises means for realizing the segment by a difference in distance separating a movable point from a fixed reference point, marking means for successively marking when the movable point is displaced in relation to the fixed point within the interval of a segment, successive divisions with their numeration in parts, and means for tying the numerical marking during movement of the movable point, relative to the fixed point, by a linear function of the first degree. The invention is especially useful for providing a mixture starting with a formulation given in parts.
