Zusammenfassung

Es werden Schnittwinkel und Dichtigkeit zweier Scharen konfokaler Hyperbeln auf der Kugel untersucht und daraus Forderungen für die Anlage solcher Felder abgeleitet.

Summary

The intersection angles and the density of two groups of confocal hyperbolas on the sphere are studied with the view to deriving from them the rules to be applied to the construction of such hyperbolic fields.

Résumé

On étudie les angles de coupe et la densité de deux groupes d'hyperboles confocales sur la sphère pour en dériver les règles à appliquer à la construction de tels champs hyperboliques.
