Abstract: A pipe grooving tool that works with commercially-available power drives. The tool attaches to the power drive using the existing tool assembly on the power drive, and allows a single operator to cut, ream and groove multiple pipe segments, without having to replace tools or otherwise alter the power drive and its tool assembly between grooving different pipe segments.

Abstract: Systems and methods for determining a power disruption index indicative that provides subscribers with a forecast of weather conditions that are likely to cause interruptions to power distributions systems within their specific areas of service. The Power Disruption Index (PDI), is a calculation of a number of forecast weather parameters including severe thunderstorm probabilities and intensities, wind speeds, wind gusts, and snowfall and ice accretion. The index combines each of these input parameters with a specific weighting based on the forecast intensity of each of the parameters, along with alert threshold criteria provided by each client utility. The output PDI is a forecast of local weather conditions for a specific local service area or power distribution network.
