  • Condensation products based on bicyclic or polycyclic aromatics or heteroaromatics
    Patent number: 8945610
    Abstract: The invention relates to a condensation product obtainable by reaction of a1) at least one bicyclic or polycyclic aromatic or heteroaromatic, where the bicyclic or polycyclic aromatic or heteroaromatic is substituted by at least one carboxyl group (—COOH), and where the carboxyl group can be present in salt form, a2) at least one carbonyl compound, a3) if appropriate at least one sulfonating agent, a4) at least one urea derivative, and a5) if appropriate at least one further aromatic or heteroaromatic, or a physiologically tolerable salt thereof.

  • Method and apparatus for vision control of welding robots
    Patent number: 5572102
    Abstract: A vision system for controlling welding robots and a method of controlling a welding robot using a vision system are disclosed. The vision system includes an ordinary unoriented light source, such as a fluorescent light source, to illuminate a part to be welded so that a light intensity gradient is created along a seam to be welded. An image of the light intensity gradient is captured by one or more fixed solid-state video cameras. The image is compared with a stored image of a reference part so that a deviation of the seam to be welded with respect to the seam of the reference part can be computed for each of a plurality of predefined reference points. The deviation at each reference point is translated by a microprocessor into a coordinate adjustment which is downloaded to a controller for the robot.
