Patent number: 6935768Abstract: The invention relates to a procedure and a micromixer for mixing at least two fluids. The aim of the invention is to reduce the mixing time of the micromixer compared to micromixers known to the art while maintaining high mixing quality and small structural dimensions. The inventive procedure is characterized by the following steps: a plurality of separated fluid currents of both fluids are brought together and alternately adjacent fluid lamellae of both fluids are formed: the combined fluid currents are carried away and a focused total fluid current is formed; the focused total fluid current is fed as fluid jet into an expansion chamber; and the resulting mixture is drawn off. The micromixer comprises a plurality of alternately adjacent fluid channels which open into an inlet chamber. A focusing channel is in fluid connection with said inlet chamber and opens into an expansion chamber.Type: GrantFiled: August 23, 2001Date of Patent: August 30, 2005Assignees: Institut fur Mikrotechnik Mainz GmbH, Mikroglas Chemtech GmbHInventors: Holger Löwe, Jōrg Schiewe, Volker Hessel, Thomas Dietrich, Andreas Freitag

Patent number: 6390161Abstract: A process is disclosed for cutting logs to form large-surface wood chips, in which, on the one hand, a rotating knife ring provided with cutting knives which are oriented parallel to its axis of rotation and, on the other hand, a quantity of logs which are likewise oriented parallel to the axis of rotation of the knife ring are moved toward one another and the logs are cut. A device for carrying out this process is also disclosed. In a device of the type mentioned above, the movement of the knife ring directed to the logs and/or the movement of the logs directed to the knife ring is carried out on a curved path at least during the cutting process. In this way, individual chip sectors are “compressed”, while others are “expanded” in such a way that there is a greater proportion of chips whose quality lies within the predetermined tolerance.Type: GrantFiled: September 17, 1999Date of Patent: May 21, 2002Inventors: Joachim Freitag, Andreas Freitag
