  • Patent number: 7449088
    Abstract: The present invention relates to a new process for obtaining fatty acids with improved color, odor and heat stability which is characterized in that: (a) in a first step the crude acids are fed to a rectification (“precut”) column in order to remove low boiling by-products being present in the starting material as a top fraction, and (b) in a second step the bottom fraction of the precut column is fed to a sidestream column in order to obtain the pure fatty acids as the side fraction, to remove low boiling by-products which have been formed in the course of the first distillation as a top fraction and to remove high boiling by-products, either being present from the starting material or formed during the first distillation, with the residue.

  • Publication number: 20040264758
    Abstract: The invention relates to a method for measuring the geometry of an object (12), particularly a work piece or a tool, by means of a co-ordination measuring device (10). The geometry of an object (12) is recorded by an optical sensor (14), for example a camera, and is represented in the form of an image content (32). Geometric structures (60 70) in the image content adapted to the measurement of the object (12), such as geometric elements or contours, are selected and subsequently evaluated. The aim of the invention is to enable even non-experienced operators to carry out a measurement in a fast and fault-free manner. When the image content (32) is changed, it is automatically analysed in relation to the geometric structures (60-70) adapted to the object measurement (12), and the adapted structures are marked and prepared for subsequent evaluation.
