1959: David Mosimann creates his first ball-bearing air turbines. Ahead of his times, he then provides them with a push button. Then the GYRO turbine family, incorporating air bearings, is born. Very soon, an internal spray will be installed in all the various models. This period corresponds to the stage of industrial production of turbines. The development of new hose connections and a push button on several models, and the selection of materials of superior quality, are all refinements designed to improve instrument reliability.
