An apparatus for making a welding seam, for example a hot-air nozzle (13), is assigned a cooling device (17). The cooling device (17) has nozzles (21) by means of which air humidified in an air humidifier (19) is blown out. The welded seam (14) made by the seam-welding apparatus (13) is rapidly cooled by the humid air and can consequently be subjected quickly to load. As a result of the rapid seam...

An amorphous metal body is produced from an intermediate product formed by compacting at least two usually crystalline components of the alloy in powder form. The alloying components in the intermediate product extend in at least one dimension at most 1 um. The intermediate product is converted into the amorphous metallic body by means of a diffusion reaction at a predetermined elevated temperatur...

A method for transferring a continuously arriving web, specifically a paper or cardboard web, from a finished product roll to a new core rotating at the speed of web travel. The new core bears in the direction of web travel and before the finished product roll on a drum around which loops the web. The web is cut longitudinally, prior to running on the drum, for forming a transfer strip. Before rea...

There is disclosed a continuous type centrifugal separator having simple structure in which the completedly closed system is realized, and which is suitable for separating the heavy and light components of the blood and usable for washing the blood of the patient.

The invention relates to a device for measuring a scatter coefficient distribution in a plane of a body. The plane is irradiated in different directions by a primary radiation beam along beam paths which are each time situated in parallel in a direction. Scattered radiation which is generated by a primary radiation beam along its path is measured by detectors which are situated on both sides of th...

A method and apparatus for minimizing a streaking effect found in reconstructed images obtained from high resolution CT scanning of a small scan circle that corresponds to a limited region of interest, such as portions of the spinal cord of a patient, particularly in scans that include concentrated high density material, such as bone, situated outside the small scan circle. The approximate range o...
