  • Patent number: 6382869
    Abstract: An above-grade trafficway barrier adapted to arrest heavy vehicles, with an obstruction member extending between opposite sides of the trafficway, and controlled by its known mass deposed upon the grade level and preferably by spaced inertia blocks deposed at opposite sides of the trafficway, the known mass not to exceed the strength of the obstruction member and coupling thereof regardless of the vehicle mass. Impact force being gradually applied and dissipated by the known mass through a lever system with simultaneous roll, turn and sliding movements of said spaced masses; whereby the obstruction member is not subjected to greater force exerted by the impacting vehicle.

  • Patent number: 5560733
    Abstract: A system for above grade and below grade installation, for rendering the mass weightless in preparation to being lifted subject to its mass inertia, wherein a pre-charge is applied to the pneumatic end of a pressure accumulator at a pre-set pressure, and an adjustment made charging the other end of the accumulator with a working fluid for balancing the mass as required against gravity and with a volume of working fluid to ensure operation, the pre-set gas pressure being increased by the adjustment to apply a working pressure for counterbalancing the mass above and below its weight as required.
