PATENTANSPRÜCHE:PATENT CLAIMS: 1. Heizkörper von sehr kleinem Durchmesser für eine mittelbar geheizte Glühkathode, dadurch gekennzeichnet, daß der wendeiförmige Heizdraht einen Stützkörper umgibt, der aus einem Draht mit einem Überzug aus Isoliermasse besteht. 1. Radiator of very small diameter for an indirectly heated hot cathode, thereby characterized in that the helical heating wire surrounds a support body, which consists of a Wire with a coating of insulating compound. 2. Verfahren zur Herstellung eines Heizkörpers nach Anspruch 1, dadurch gekennzeichnet, daß auf den Draht vorteilhafterweise unter Verwendung eines Bindemittels fein zerteilter Isolierstoff, insbesondere ein Metalloxyd, aufgebracht und auf den Draht aufgesintert wird.2. A method for producing a radiator according to claim 1, characterized in that that on the wire advantageously finely divided using a binder Insulating material, in particular a metal oxide, is applied and sintered onto the wire.
