Abstract
A vibration-proof and earthquake immune mount system connecting machinery or a structure to a foundation which may be subject to external vibrations or earthquakes. The mount system includes a number of mounts operating in conjunction with a number of dampers, and both the mounts and the dampers function regardless of the direction of the external disturbance. In the mount this ominidirectionality is achieved by using a low-friction rolling contact between a ball attached to the machinery or structure and a dished surface attached to the foundation. Damping is provided by eddy current dissipation when a conductor plate attached to the structure of machinery and free to move in two directions is placed between the poles of an electromagnet which is integral with the foundation, and activated by a controller energized when a sensor detects motion of the foundation.
