  • Impulse-responsive rotary actuator for storm drain barrier not disabled by immersion
    Patent number: 7238279
    Abstract: A pivoted gate across an opening from a gutter into a collector basin. An actuator inside the basin is insensitive to slow flow rates, but includes a rotor with vanes that actuate an opening linkage at sufficiently high rates of flow. A float is included in the actuator to exert a gate-opening torque when the rotor is flooded.
    Type: Grant
