Abstract

"GIROSCóPIO VIBRATóRIO". A invenção tem por objeto um giroscópio vibratório, comportando um cilindro vibratório (1) excitado magneticamente ou eletrostaticamente, sobre o qual são colocadas massas (19) regularmente repartidas e destinadas a baixar a freq³ência de vibração desse cilindro. O giroscópio assim realizado é muito mais preciso que os modelos clássicos permanecendo muito económico e simples de realizar. A invenção se aplica cada vez que for preciso medir uma rotação angular ou uma velocidade angular.
