Abstract: A valve tester system is disclosed that comprises a valve tester assembly for rotating a valve stem of a valve. The valve tester assembly may include a support, a rotation element mounted on the support for rotating a valve during a rotation event, a control element for controlling aspects of the rotation event of the valve by the rotation element, and an element for detecting a location of the valve tester assembly during the rotation event of the valve. In some embodiments of the invention, the element for detecting the location of the valve tester assembly includes a Global Positioning Satellite (GPS) receiver. In some embodiments, the GPS receiver is integral with the control element.

Abstract: A valve tester assembly is disclosed that includes an articulated arm assembly having a first end and a second end, with the second end of the articulated arm assembly being movable away from and toward the first end such that when the first end of the articulated arm assembly is connected to a vehicle, the second end of the articulated arm assembly is movable away from and toward the vehicle. The assembly includes a rotation mechanism that is mounted on the articulated arm assembly toward the second end of the articulated arm for rotating a shaft for exercising a valve. The assembly further includes a moving mechanism that is mountable on a vehicle for moving the first end of the articulated arm assembly away from and towards the vehicle.

Abstract: A smoke producing system for efficiently producing reduced toxin smoke includes a heating chamber heated by a heat source. A coil passes into and through the heating chamber to deliver a smoke producing substance, typically a liquid, to the hottest portion of the heating chamber. The substance is heated above a flash point of the substance before it is released from the coil into the hottest part of the heating chamber where it is immediately converted to smoke. The smoke then passes from the hottest portion of the chamber through a convoluted path to an outlet port. In a particular embodiment, the smoke producing system incorporates a fan assembly used as the heat source and for directing the smoke produced in a desired direction.

Abstract: A deflection gauge dislodging system for performing deflection tests of pipes while permitting the deflection gauge to be readily dislodged from the interior of the pipe should it become stuck in the pipe. The deflection gauge dislodging system includes an elongate deflection gauge for measuring a minimum diameter of a lumen of a pipe. A dislodging apparatus is provided for dislodging the deflection gauge from a lodged condition in the lumen of a pipe. The dislodging apparatus is adapted to impact against the deflection gauge while the deflection gauge is positioned in the lumen of the pipe.
