Abstract: A system for measuring the conductivity of a flexible media positioned between a conductive backing and a conductive roller, wherein the conductive roller contacts the flexible media in a roller contact region. A pressure control mechanism presses the conductive roller against the second surface of the flexible media with a specified contact pressure, and a motion control system provide a relative motion between the conductive roller and the flexible media. A resistance measuring system connected to the conductive roller and the conductive backing measures the conductivity of the flexible media within the roller contact region. A data recording system records the measured conductivity of the media as a function of position.

Abstract: A clasp knife has a pivotally mounted blade which can be swung between an operative extended position and a shrouded position within a body and handle using only one hand. The knife incorporates an actuating lever carrying a latching dog which locks the blade to the lever when the blade and the body are swung from the closed position to the open position while a release member is in a locking position. When the body is swung to the extended position while the release member is in the release position, the latching dog is released from the blade and the blade is detained in the body as the body is swung back to the inoperative closed position.
