  • Patent number: 4492873
    Abstract: An apparatus for electron beam irradiation of objects comprises an electron beam shaper 1 providing a ribbon-shaped beam 7 and a deflecting electromagnet 8 with a frame-type magnetic circuit 9 to direct the beam 7 onto an irradiated object 6 substantially at an angle of 90.degree.. The deflecting electromagnet 8 has two poles 10, 11 extending over the width of the irradiated object 6 and two windings 12, 13 embracing the poles 10, 11 and connected to a direct current source 14, the deflecting electromagnet 8 being arranged so that the trajectories of the electrons within the area from the shaper 1 to the deflecting electromagnet 8 are inclined to the frame of its magnetic circuit 9.

  • Patent number: 4441150
    Abstract: A high voltage rectifier unit comprises a vessel filled with an electrically insulating fluid and accommodating a transformer having a sectionalized secondary winding, each section 7 of which is provided with a metallic shield and includes two coils 9, a high-voltage lead 27, rectifier devices 15 mounted on supporting insulators 25. Each section of the secondary winding of the transformer is connected with one of the rectifier devices 5 and forms a rectification stage. The metallic shields are made as open metallic rings 10 separated by insulating rings 18. On the outer surface of each of the metallic rings 10 are secured coils 9 of one of the sections 7 of the secondary winding, connected with the metallic ring 10 by inner leads 11 of each coil 9 of the section 7 of the secondary winding.
