Abstract

a. Perfectionnements aux gyroscopes. b. L'invention décrit un gyroscope biaxial accordé sec comportant une boucle de rééquilibrage pulsée. Ce montage élimine la nécessité d'un convertisseur analogique/numérique puisque le couple du gyroscope est produit par des impulsions en utilisant une source de courant constante Une autre particularité réside dans un réseau de mise en forme intercanaux qui échange d'un axe à l'autre des signaux d'erreur amortis électroniquement. Au moyen du réseau d'addition qui combine les signaux d'erreur du canal principal et du canal transversal avec les signaux d'une source de tension en dents de scie, un signal passant alternativement du négatif au positif est appliqué au générateur de couple du gyroscope. c. Fabrication de gyroscopes.
