  • Process for forming notches in an irrigation lateral
    Patent number: 5248217
    Abstract: A process for forming notched irrigation laterals uses a construction laser adapted to propagate radiation along a planar path, and a device that both detects the radiation and is used to manually form notches in the lateral. The laser is positioned relative to the longitudinal axis of the lateral so as to minimize optical interference during the formation process.
