  • Rotary Irrigation Sprinkler With A Turret Mounted Drive System
    Publication number: 20110017842
    Abstract: Disclosed are rotary sprinklers having a turret mounted drive system. In one aspect, the complete drive mechanism, including all components thereof, is positioned in the rotary turret portion of the rotary sprinkler. In another aspect, the turret mounted drive system includes a main drive element, such as a turbine, paddle wheel, or the like, positioned adjacent a flow passage or nozzle outlet and oriented to be driven from a fluid flow projected from the sprinkler. In yet another aspect, the turret mounted drive system also has associated gearing assemblies, which may include appropriate gear reduction modules, also mounted within the turret, but outside of the fluid flow path.

  • Ignition coil driver device with slew-rate limited dwell turn-on
    Publication number: 20060213489
    Abstract: A device to control the charging rate of an ignition coil for an internal combustion spark ignition engine. The device controls the turn-on rate of the primary coil by slew-rate limiting using switching devices and a Miller-effect capacitor in order to reduce secondary oscillation magnitudes originated by a sharp transition of the controlling switch.
