A magnetic coupling for a device, such as a cathode, which is received in a vacuum bulb of a tube which has shafts for mounting the tube for rotation on an axis, has an inner ferromagnetic part disposed in the vacuum bulb and connected to the device and an outer ferromagnetic part which is arranged outside of the vacuum bulb and aligned with the inner part. The outer part comprises a magnetic arrangement having a plurality of pole pieces to which the poles of a ferromagnetic yoke that forms the inner part are allocated.

Magnetic coupling for a rotating X-ray tube

Amorphous metal tapes are produced by expressing a metallic melt in a supply container through at least one nozzle opening onto a moving surface of a cooling body positioned in relatively close proximity to the nozzle opening. The nozzle opening is 1.5 through 6 mm wide, as measured in the direction of motion of the cooling body surface, which is positioned at a distance of about 0.005 through 0.6 times the width of the nozzle opening from such opening and is moved at a velocity of at least 5 meters per second past such nozzle opening.
