Abstract: A method for measuring large components, including providing a large component with markings on at least one outer surface at predefined and spaced-apart locations, providing a camera sensor system having at least one camera and one image analysis device for evaluating a camera image, wherein the position and orientation of the camera in relation to a reference point at a distance from the camera are determined, recording camera images of the individual markings using the camera and transmitting the camera images to the image analysis device, evaluating the camera images using the image analysis device, wherein the position of the individual markings in relation to the position of the camera is determined, and calculating the position of the markings in relation to the reference point from the position of the camera in relation to the reference point and the position of the markings in relation to the camera.

Abstract: Carbon monoxide is produced in an improved process in a carbon-filled, water-cooled generator in the configuration of a truncated cone in the longitudinal section, by the gasification of said carbon with a mixed gas of oxygen and carbon dioxide, wherein the improvement comprises injecting the mixed gas into the generator through at least one downwardly-directed, coolable nozzle arranged in the generator sidewall and removing the carbon monoxide formed.

Abstract: The instant invention is directed to a process for the continuous production of aromatic polyisocyanates containing uretdione groups. The process broadly comprising dimerizing an aromatic polyisocyanate in a continuous, coolable screw reactor at a temperature of from -30.degree. to +70.degree. C.
