Abstract: 1429058 Electron beam irradiation apparatus LICENTIA PATENT - VERWALTUNGS GmbH 13 Aug 1973 [24 Aug 1972] 38290/73 Heading H1D Irradiation apparatus comprises a horn having conical inner and outer parts 1, 2 defining a vacuum chamber, electron generator (and accelerator) 10, electric and/or magnetic field deflector 9, and annular electron output window 4 secured mechanically to the horn without auxiliary webs. Parts 1 and 2 may be connected by water cooled webs in vacuum space 3, the webs being narrow transverse to the beam and wide in the beam direction. The window may be secured by rings 5, 6 and flanges 7, 8.

Abstract: The present invention relates to systems which utilise a very thin electron beam (diameter one-tenth of a micron or less) to reach a point upon a given surface or to write-in an information there or to read one information therefrom. The object of the invention is to achieve a relative accuracy in the order of 10 5 to 10 6.

Abstract: Spinel has compsn. Mg1-xZnx Mnv Cuz Fe2(1-e)O4, when 0.4 = x =0.5, 0 = y =0.16, 0 = z =0.02, 0 = e =0.06 and may have impurities (Ca, SiO2) of the order of 1-3 mol.%. Compsn. finds use in magnetic circuits working at low and medium frequencies esp., for the inner core and outer screening of induction coils in TV. Prod. has a high enough resistivity to make it unnecessary to use insulator between core and coil turns.
