  • Interceptor actuated by seismic vibrations
    Patent number: 4058134
    Abstract: An interceptor apparatus actuated by seismic and other vibrations comprising a substantially vertically movable rod, a weight capable of engagement with the rod and a plurality of pivotable support arms supporting the weight within a housing and held in a mechanically balanced state in entirety. When the apparatus undergoes seismic or other vibrations, the mechanical balance is lost, whereupon the weight is released from the support arms and is allowed to fall together with the vertically movable rod due to the gravitational forces, thereby effecting the switching of a related fluid circuit or electric circuit.
