PATENTANSPRÜCHE:PATENT CLAIMS:1. Anordnung zur Berichtigung von Verzerrungen in Kathodenstrahlröhren mit unsymmetrischer
Schaltung, dadurch gekennzeichnet, daß einerseits die nach dem Strahlerzeuger zu gelegenen Ränder der Platten des
zweiten Paares eingekerbt sind und andererseits ein vorzugsweise zylindrischer Schirm zwischen
den beiden Plattenpaaren angeordnet ist.1. Arrangement for correcting distortions in cathode ray tubes with unbalanced
Circuit, characterized in that on the one hand the edges of the plates of the to be located after the beam generator
second pair are notched and on the other hand a preferably cylindrical screen between
the two pairs of plates is arranged.2. Anordnung nach Anspruch 1, dadurch gekennzeichnet,
daß die hinteren Ränder der Platten des zweiten Paares mit verkleinertem Radius gekrümmt sind.2. Arrangement according to claim 1, characterized in that
that the rear edges of the plates of the second pair are curved with a reduced radius.3. Anordnung nach Anspruch 1, dadurch gekennzeichnet,
daß die Platten des zweiten Paares gebogen sind (Fig. 7).3. Arrangement according to claim 1, characterized in that
