Abstract: The present invention provides a high voltage transformer consisting essentially of a magnetic iron core, yokes and primary and secondary coils, with high voltage rectifier and fine control element for the energy supply of single and multistage electron accelerators, wherein the primary coil is such a distance from the secondary coil that a large stray field results, the ratios of yoke to limb lengths being from 1:1 to 2:1.

Abstract: The present invention provides a process for the desulfurization and denitration of flue gases by electron irradiation of the flue gases to which ammonia has been added prior to the irradiation, wherein for the electrons there are used low-energy sources of electron beams with an acceleration voltage for the electrons of 250 keV, only one of which has an electron exit window, the support lattice of which is formed from several double comb-like bridge elements disconnectably connected with the windowframe, each of which has a main bridge which is provided with a bore as cooling pipe.

Abstract: An electron beam source with an electron exit window which is connected thereto and which essentially consists of the window frame, of a support grid, optionally provided with cooling lines, for the foil permeable to electrons and of the foil permeable to electrons. The grid is formed by one or more bridge elements each in the shape of a double comb formed by milling slots to extend inwardly from each of a pair of opposite side edges of a substantially rectangular metal plate to terminate at a main bridge element extending substantially centrally of the plate and substantially parallel to the opposite edges. The bridge elements are secured to the window frame solely by disengageable mechanical fastening elements, and no welding or brazing, either in forming the bridge elements or in securing them to the window frame, are involved.

Abstract: A process is provided for coating metal surfaces with synthetic resins in which, prior to application of synthetic resin, said metal surfaces are irradiated with high energy rays in presence of at least one organic compound and/or of at least one organosilicon-oxygen compound (silicones) and only then is the metal surface coated with synthetic resin in the usual manner.
