Abstract: The present invention provides a method for obtaining densified material comprising the steps of a. providing lignocellulosic material, b. delignification of the lignocellulosic material providing a delignified material, wherein the delignification step is performed in such a way that the lignin of the lignocellulosic material is almost completely removed and wherein the structural integrity of the lignocellulosic material is maintained in the delignified material, c. densification of the delignified material providing a densified material. Furthermore, a densified material is provided. The fibers and fibrils are maintained in the structural directionality of the raw material and that the cellulosic material is whitish.

Abstract: An arrangement with a control circuit for controlling a numerical value for patient respiration as well as to a process for controlling the numerical value. The numerical value is controlled on the basis of an evaluation of the EEG (electroencephalogram) of the patient (1) by an EEG sensor (2), e.g., by determining the so-called BIS (bispectral index). A control of the inspiratory gaseous anesthetic concentrations is cascaded to the control of the EEG value in the manner of a cascade circuit. This has the advantage that a metering device (6) belonging to the arrangement meters a gaseous anesthetic mixture directly according to the patient's needs. As an alternative, the control of the numerical value is performed on the basis of an evaluation of the expiratory gaseous anesthetic concentrations resolved for individual breaths at the Y-piece (19) of the respiration circuit (12) by a gaseous anesthetic sensor (8a), preferably an infrared optical gas sensor.

Abstract: The invention relates to a method for processing a work piece by removing material with a tool in which the tool is guided over the work piece in paths. The pivoting and cambering angle of the tool is selected in every point such that the width of a tolerance zone is optimized. Within said zone, the effective zone (K) of the tool is located in a tolerance zone of the desired specified surface (Psi) of the work piece. The distance between two points (Pl, Pr) is maximized, said points characterizing the furthest outlying points of the tolerance zone. As a result, it possible to produce surfaces having a high precision with a small number of paths.
