  • Non reactive positioning device
    Patent number: 4101009
    Abstract: The vibration forces between a frame and a continuously oscillating mass are absorbed by making the oscillating mass system and its drive means equal and by fitting each such system and means to the frame with identical resilient elements such that oscillation movements of system and means occur out of phase one with the other to absorb the exciting vibration forces.
    Type: Grant
    Filed: January 26, 1977
