Abstract: A device for the simultaneous continuous feeding of pulverulent solids and of liquids into a treatment machine wherein the casing of the machine is provided with an orifice for feeding in liquids and solids. A feed branch extends upwardly from this orifice and leads into a ring passage. Positioned on the inner wall of the feed branch is an orifice for feeding liquids to the treatment machine and located in the center of the ring passage is a device for feeding solids to the treatment machine. The free cross-sectional size and shape of the orifice is adjustable and may be varied, in a simple manner, by modifications to the structures of the ring passage and orifices. In the cylindrical section of the feed branch several annular rows of bores, having differing diameters in each of the rows, form an orifice for the liquid feed. The bores within one row are arranged offset tangentially relatively to the direction of the adjacent bores in the other rows.

Abstract: A system for mixing of wood chips or the like with glue which involves an intensive movement of the chips during the addition of the glue and a subsequent thorough mixing of the glue and the chips in a ring of material to be mixed, is characterized by steadily accelerating the chips out of an axial motion via a centrifugal and helical motion and by the addition of the glue during this acceleration, the acceleration to the velocity of the ring of material to be mixed taking place only following the addition of the liquid.

Abstract: A de-aerating agitating mill, especially for paints, pigments and the like in which the mixing chamber is closed off from a discharge chamber which may be subjected to reduced pressure. The closure is effected by a separator device consisting of a central disk which is attached to the stirrer or agitator shaft and rotates in a hole within a stationary part of the casing. A narrow, annular gap between the periphery of the disk and the rim of the hole acts as an outlet channel through which the ground or mixed stock is extruded. The shear stresses exerted on the stock rupture the material and burst any air bubbles which are then removed by the vacuum.
