Zeichungunge:
Fig. 1 is a side elevation, with parts in section, of one embodiment of the invention,
Fig. 2 is a side elevation of a combined generator and X-ray tube installation, the generator being adapted to produce potentials of the order of several million volts,
Fig. 3 is a diagrammatic view of the charge transferring system of the generator shown in Fig. 2,
Fig. 4 is a side elevation, with parts in section, showing a unit having a charge carrier of disk form
Fig. is a somewhat diagrammatic fragmentary side elevation, with parts in section, of a unit having a fluid charge carrier, and
Fig. 6 is an enlarged fragmentary view of the carrier system of Fig. 5.

It will be apparent that, as each charged belt passes by the brushes 10, the charge passes from the belt to the brush, and thence to the interior surface of the electrode 4. As charges cannot remain upon the interior surface of a hollow body, the electrical charges pass to the exterior surfaces of the electrodes.

.. to which is secured'a bracket 2 that carries an insulator column 3.
The insulators 3 may be, and preferably are, glass rods of a height sufficient to provide adequate insulation between the grounded base 1 and hollow electrodes 4 that are mounted on the rods 3
The belts 6 constitute the charge carriers which transfer to the electrodes the electrical charges which are established at the lower ends of the belts. The apparatus for charging the belts is shown diagrammatically in Fig. l, as an alterhating current source 11, a transformer 12, and a rectifier 13 in the secondary circuit of the transformer
->>Also der Wechselstromgenerator 11,12,13 mit einseitiger positiver Ladungsspannung bis zu 5000 Volt
The belts 6 constitute the charge carriers which transfer to the electrodes the electrical charges which are established at the lower ends of the belts.
