    Abstract: A thermionic emitter has a flat emission surface that is subdivided by slits into generally spiral or serpentine conductor sections, the surface having legs extending therefrom that form part of the current supply terminals and that also serve for securing the emitter. Each of these legs has a portion with a longitudinal electrical resistance that is elevated compared to that of the conductor sections, such that areas of maximum temperature migrate from the middle of the emitter to its edges as the heating current increases.

    Abstract: An anode for an x-ray tube has an incident surface on which an electron beam is incident for generating x-rays emanating from a focal spot. In at least that region wherein the focal spot is located during operation of the x-ray tube, the incident surface has a step-like structure with end faces that reside at a substantially right angle relative to the electron beam during operation of the x-ray tube. The end faces are connected by respective sidewalls, and backscattered electrons from the end faces strike the sidewalls and generate x-rays in addition to x-rays emanating from the end faces struck by the electron beam, thereby improving the efficiency of x-ray generation. A similar improvement can be achieved by an anode having a roughened surface in the region of the focal spot.

    Abstract: The present invention is directed to a method for removing organic substances from aluminate liquors of the Bayer process. The method comprises the steps of contacting the liquor with an oxygen containing gas under elevated pressure in the presence of metallic ions acting as a catalyst to oxidize the organic substances, precipitating the metallic ions jointly with aluminum hydroxide, separating the precipitate from the oxidized liquor and recycling the precipitated aluminum hydroxide containing the metallic ions into the oxidation step as a catalyst carrier.
