  • Patent number: 7695556
    Abstract: A system, method, and ink for printing a data carrying mark on a green ceramic honeycomb structure is provided. The system includes a printer having an ink jet print head that prints a mark, preferably in the form of a two-dimensional data matrix barcode, on a side wall of the green ceramic honeycomb structure. The ink may be a heat resistant ink that comprises a mixture of a glass or glass ceramic frit and a metal oxide colorant. An optical reader is provided for determining if the data is accurately reproduced in the printed mark, as well as any noise factor which may be present due to defective printing. The system includes a turntable that positions the green body for the printing operation, and then rotates the green body to position the printed mark first in front of a dryer, and then in front of the optical reader to determine the quality of the mark. Marked green and ceramic honeycombs are also provided as well as a method for repairing a defective applied bar code on a honeycomb structure.

The present invention further relates to a getter composition utilizing low-softening temperature glasses comprising, based on weight %, 1-50% SiO2, 0-80% B2O3, 0-90% Bi2O3, 0-90% PbO, 0-90% P2O5, 0-60% Li2O, 0-30% Al2O3, 0-10% K2O, 0-10% Na2O, and 0-30% MO where M is selected from Ba, Sr, Ca, Zn, Cu, Mg and mixtures thereof. The glasses described herein may contain several other oxide constituents that can substitute glass network-forming elements or modify glass structure. The desiccant material is pre-hydrated to reach its saturation level of moisture absorption. The process of pre-hydration can be done by exposing the desiccant in a normal temperature/humidity environment of for example, 25° C. and 50-60% RH. For 24 to 48 hours or up to the time when weight gain (due to moisture absorption) stops increasing.

  • Publication number: 20080053333
    Abstract: A system, method, and ink for printing a data carrying mark on a green ceramic honeycomb structure is provided. The system includes a printer having an ink jet print head that prints a mark, preferably in the form of a two-dimensional data matrix barcode, on a side wall of the green ceramic honeycomb structure. The ink may be a heat resistant ink that comprises a mixture of a glass or glass ceramic frit and a metal oxide colorant. An optical reader is provided for determining if the data is accurately reproduced in the printed mark, as well as any noise factor which may be present due to defective printing. The system includes a turntable that positions the green body for the printing operation, and then rotates the green body to position the printed mark first in front of a dryer, and then in front of the optical reader to determine the quality of the mark. Marked green and ceramic honeycombs are also provided as well as a method for repairing a defective applied bar code on a honeycomb structure.
