摘要:
A skinning apparatus including: a manifold having: a chamber, one or more channels, or both, to receive a source of flowable cement and to direct the received flowable cement to an interior skinning region or skinning chamber surrounding at least a portion of the lateral surface of a first article received in the skinning chamber, and to form a cement skin on the lateral surface of the received article; a source of motive force to controllably urge the received article into and through the skinning chamber; and a support member to receive and support the resulting skinned article. Also disclosed is a method for skinning a ceramic article using the aforementioned skinning apparatus, as defined herein.

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.

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).
摘要:
A system, apparatus and method for detecting defects in a honeycomb body. The system and apparatus include a fixture adapted to hold the honeycomb body, a particulate fluid source, a pipe which defines a flow path between the particulate fluid source and a first end face of the honeycomb body thereby allowing particulate fluid to flow from the particulate fluid source to the first end face of the honeycomb body. The particulate fluid emerges at a second end face of the honeycomb body through defects, if any, in the honeycomb body where the positions of such defects may be monitored. The system and apparatus includes a flow straightener disposed in the flow path to minimize boundary layer influence of the pipe on the flow of the particulate fluid. A substantially uniform velocity flow profile is provided to the first end face of the honeycomb body.
