The single-axis inertial platform... The angular motions of the controlled member are sensed by the single-axis gyro. The output signal of the gyro is electronically processed and fed to the torque motor(TM) of the stable element and to the torque generator(TG) of the gyro. The problem is to determine how to do the electronic processing so that the controlled member maintains its orientation in spite of disturbances. The voltage across the output signal generator(SG) of the gyroscope is proportional to the integral of the angular velocity of the controlled member about the gyroscope's input axis. Consequently, this signal is fed to an amplifier and then to a motor, which drives the controlled member in the proper direction to null the ouptut of the gyroscope. 1, record 1, English, - output%20signal%20generator

The directional gyroscope forms a standard reference for the pilot and navigator. It is a three-frame gyroscope with its spin axis in the horizontal plane. As soon as tilt develops, a switch is closed between the gyroscope housing and the vertical gimbal ring and a motor introduces a torque in the horizontal plane that causes the gyroscope to precess back toward the horizontal. 3, record 2, English, - vertical%20gimbal%20ring
Record number: 2, Textual support number: 2 CONT
The source of power for the gyro is the engine-driven vacuum pump (or venturi) which sucks air from the rear of the instrument case. This causes air under atmospheric pressure to pass through the filtering system, thence through an air bearing into the hollow vertical gimbal ring. The air then passes through the air nozzle and jets, striking the rotor at a point just above the plane of the horizontal gimbal. 4, record 2, English, - vertical%20gimbal%20ring

Le gyroscope de Foucault est une toupie rectifiée avec grande précision, formée d'une masse de cuivre de forme torique ou ellipsoïde, montée sur un axe dont les deux extrémités sont fixées sur un anneau lui-même suspendu aux deux extrémités du diamètre perpendiculaire à celui de l'axe qui porte la masse de cuivre, de sorte que celle-ci peut prendre toutes les inclinaisons possibles sur l'horizon. Les deux pivots de ce premier anneau reposent sur un deuxième anneau plus grand, monté lui-même sur pivots lui permettant une rotation verticale. [...] Si on fixe horizontalement l'anneau intérieur, l'axe de rotation ne pourra plus se déplacer que dans un plan horizontal. L'expérience et la théorie indiquent que la masse exécute une série d'oscillations autour de la méridienne, sur laquelle il vient finalement se fixer quand les frottements ont absorbé ce mouvement oscillatoire, pourvu toutefois que la rotation de la toupie dure assez longtemps. Si, au contraire, on fixe l'anneau vertical dans un plan perpendiculaire au plan méridien, l'axe de rotation ne pourra plus se déplacer que dans ce plan méridien. 1, record 2, French, - anneau%20vertical
