Abstract: The invention relates to a method of combined cell digestion and extraction of oil-containing seeds having an oil content of >30% by mass, wherein production of a slurry from the oilseeds and ethanol is followed by a combination cell digestion with a subsequent ethanolic extraction, wherein the smaller portion of the oil of the oilseed and the alcohol-soluble constituents present therein are dissolved in the ethanol in accordance with the dissolution capacity of the ethanol for the oil and the alcohol-soluble constituents, a greater portion of the oil is displaced from the seed cells by the ethanol, forming a free oil phase in the ethanol. The free oil phase is removed and, according to the invention, has semi-raffinate quality, reducing the complexity of refining as an advantage of the method of the invention.

Abstract: A method for restarting a robot after a premature interruption of a processing program, which controls it, at an interruption point. The robot has an atomizer apparatus for automatic coating of workpieces, and the processing program is used to preset a nominal movement of the atomizer apparatus with respect to a workpiece, which is to be coated and can be moved by means of a feed device, and to preset the associated nominal atomizer parameters. After the interruption of the processing program, the atomizer apparatus is first of all moved to a restarting point, which is located on the nominal movement path and is located ahead of the interruption point. After this, the atomizer apparatus is then moved on the nominal movement path, corresponding to a predeterminable velocity function, to a transfer point which is located on the nominal movement path and is located behind the interruption point. The atomizer apparatus is switched on again between the restarting point and the transfer point.

Abstract: An exemplary paint material switching path includes first and second valve elements, each having an inlet and an outlet, and a hollow cylindrical intermediate piece arranged between the outlet of the first valve element and the inlet of the second valve element. The inlet of the first valve element is configured to be connected to a continuously pressurized paint material supply, and a manifold channel which is configured to be pressurized and into which the outlet of the second valve element opens. Furthermore, components are provided for measuring the pressure prevailing in the hollow cylindrical intermediate piece and an evaluation device for detecting leaks in at least one of the two valve elements based on the measured pressure with respect to time for a given pressure difference between the inlet of the first valve element and the outlet of the second valve element at the beginning of the leak detection.

Abstract: A method for determining spraying parameters for controlling a paint-spraying apparatus using a spraying agent is disclosed. A known spray pattern is provided which has been determined by means of known spraying parameters for the use of a first spraying agent. A provisional spray pattern is calculated using the known spraying parameters and the characteristics of a second spraying agent. The known spraying parameters are altered in order to acquire changed spraying parameters which yield a further spray pattern. The changed spraying parameters are altered to the point where the further spray pattern is similar to the known spray pattern within a similarity criterion. The changed spraying parameters corresponding to the further spray pattern are intended as spraying parameters for the second spraying agent and are provided to the paint-spraying apparatus whenever the second spraying agent is used.

A known spraying map is produced, using known spraying parameters and paint amount, for a predetermined movement speed of the painting appliance, and a paint amount is matched to a new movement speed in comparison to the predetermined movement speed. Furthermore, new spraying parameters are calculated for the adapted paint amount, while maintaining a spraying map which is similar to the known spraying map.
