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: The invention relates to a controllable flow pourer mechanism.This pourer mechanism comprises a valve mounted on an actuating device, of such construction that in closed position, the valve is kept in fluid-tight contact upon the lip of the pourer spout and that, from this position, in a first phase, the valve slides upon the lip of the pourer spout and, in a second phase, the valve carries out a rocking movement.The invention is applied especially to effect mixtures of liquid products.

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.
