    摘要: A method for detecting defects in a honeycomb filter body. In operation, a gas flow stream containing particulates emerges at an outlet end face of the honeycomb body through defects, if any, in the honeycomb walls and/or plugs where they are illuminated. The gas flow stream containing the particles are provided at varying flow rates, pressures and particle densities during the course of the test cycle, thereby improving the signal-to-noise ratio, and reducing turbulence within the gas flow stream such that any defects within the filter body may be more readily detected.

    摘要: A pull roll apparatus and method are described herein that can control a cross-draw tension and a down-draw tension of a glass sheet while manufacturing the glass sheet. In one embodiment, the pull roll apparatus includes a first driven stub roll pair, a second driven stub roll pair and a control device (e.g., PLC) that controls the first and second driven stub roll pairs while a first edge portion of the glass sheet is drawn between two vertically downtilted rolls associated with the first driven stub roll pair and while an opposing second edge portion of the glass sheet is drawn between two vertically downtilted rolls associated with the second driven stub roll pair. If desired, the pull roll apparatus may include a pulling roll assembly (located below the first and second driven stub rolls) or another set of driven stub roll pairs (located below the first and second driven stub roll pairs).
