A method for cleaning batch material from an extrusion die includes introducing at least one gel composition into the die in a manner sufficient to purge the batch material from the die. After the batch material is purged from the die, the die can be treated further so that the gel composition is liquefied and flows from the die.

Disclosed are compositions for applying to honeycomb bodies. The compositions can be used as plugging mixtures for forming a ceramic wall flow filter. Alternatively, the compositions can be used to form skin coatings on exterior portions of a honeycomb body. The disclosed compositions include an inorganic powder batch composition, an organic binder, a liquid vehicle, and a rheology modifier. The compositions exhibit improved rheological properties, including an increased yield strength and reduced viscosity under shear, which, among various embodiments, can enable the manufacture of sintered phase end plugs having reduced levels of dimple and pinhole formations in the final dried and fired end plugs as well as end plugs having relatively uniform and desired depths. Also disclosed are methods for forming end plugged ceramic wall flow filters from the plugging mixtures disclosed herein.

A polarization mode dispersion compensator corrects polarization mode dispersion in an optical signal having a fast polarization mode component, a slow polarization mode component and a time differential between the components. The compensator includes a phase shifter and a variable delay section. An input of the phase shifter is coupled to an optical device that provides an optical signal that exhibits polarization mode dispersion. The phase shifter functions to rotate the optical signal principal states of polarization to a desired orientation. The phase shifter engages a segment of an optical fiber that is coated with a radiation cured coatings. The coating composition is selected so that in response to a preload comprising the application of a stress of about 80 MPa to said coating at about 80&deg; C. and after a stress-relaxation period of at least about 1 hour, at about 80&deg; C., a residual stress exhibited by said coating comprises at least about 60 MPa, and the coating is capable of transmitting a transverse stress to the fiber to controllably change the birefringence of the fiber.

The present invention relates to a radiation curable ink formulation which has a tan .delta. of from about 0.5 to about 1.5. The radiation curable ink formulation includes a pigment, a radiation cross-linkable monomer or oligomer, and a rheology modifier. Flat panel color filters which contain a black radiation curable ink formulation and one or more colored radiation curable ink formulations are also disclosed. At least one of the black and colored radiation curable ink formulations has a tan .delta. of from about 0.5 to about 1.5 and includes a pigment, a radiation cross-linkable monomer or oligomer, and a rheology modifier.
