Abstract: A combination gripping and cutting tool for cutting pipe and gripping can lids includes a pair of handles that are rigid. Each handle comprises a grasp that is arcuate. The handles are pivotally coupled, such that the grasps are opposing. A support, which is arcuate, extends transversely from a respective grasp. A channel is positioned in the support. A blade that extends transversely from a respective grasp is complementary to and positioned through the channel. Each of a pair of cutouts is positioned in a respective grasp. The cutouts are arcuate and opposing. Each of a pair of grips is coupled to a respective cutout. The grips are configured to engage a lid of a can when the grasps are pivoted inwardly. The handles are positionable with the support separated from the blade, such that a pipe is positionable between the blade and the support for cutting.

Abstract: A system and method for determining “real time” air leakage from a duct involves an airflow meter for taking airflow measurements at the inlet and at the outlet of the duct. Also included is a base fan that operates in three different modes to simultaneously vary an enclosure pressure at the inlet and outlet. This is done while a duct fan, inside the duct, is operated to continuously move air through the duct. A comparison of airflow measurements at the inlet, or at the outlet, under the three base fan operational modes will respectively identify whether leaks are present in the duct, upstream or downstream from the duct fan.
