219469, 219216, 399 69, 399279, 399286, 430350

Abstract:

A thermal processor including a rotating drum including an internal heater configured to heat and maintain the drum at a desired set-point temperature, and a plurality of pressure rollers, including a first pressure roller, circumferentially spaced along a segment of the drum. A temperature sensor is configured to provide a temperature signal indicative of a temperature proximate to the first pressure roller. A controller is configured to adjust the desired set-point temperature based on the temperature signal.

International Classification:

G03C 5/00
G03B 15/00

US Classification:

430350, 396575

Abstract:

A thermal processor for use in developing an image in an imaging material which is transported along a transport path through the thermal processor. The thermal processor includes a preheat assembly for preheating the thermally processable material to the threshold temperature. The preheat assembly includes a heated member having a major surface facing the thermally processable material. A dwell assembly is provided for thermal development of the image in the thermally processable material. Means are provided for moving the thermally processable material along the transport path through the preheat assembly and the dwell assembly including a roller assembly which contacts the thermally processable material. The roller assembly includes rollers positioned between the heated member and the thermally processable material. Means are provided for reducing optical density loss in the thermally processable material, including means for selectively changing the temperature of the heated member as the thermally processable material moves along the transport path.

Appl. No.:

8/922278

Inventors:

Kent R. Struble - Woodbury MN
David J. McDaniel - Cottage Grove MN

Assignee:

Imation Corp. - Oakdale MN

International Classification:

G03G 1528
G03D 700

US Classification:

219216

Abstract:

A thermal processor and method for using the same which is particularly useful for developing a sheet of imaging material, such as photothermographic film. The thermal processor includes means for transporting the imaging material through the apparatus. The thermal processor also includes means for heating the imaging material to develop the image in the imaging material. The thermal processor also includes a fog reduction system which removes a gaseous by-product emitted from the imaging material which may cause fogging of the image as the image is developed on the imaging material.

Filed:

Appl. No.:

8/540094

Inventors:

David J. McDaniel - Minneapolis MN
John J. Allen - Mendota Heights MN
Robert M. Biegler - Woodbury MN

Assignee:

Imation Corp. - Oakdale MN

International Classification:

B41J 247

US Classification:

347263

Abstract:

A thermal processor includes an air flow preventing means that substantially prevents the flow of air from a processor exit into a thermal processing compartment. The prevention of air flow reduces processing defects that otherwise could occur in sheets of thermally processed material handled by the thermal processor. The reduction of processing defects enhances the quality of the sheet of thermally processed material. In particular, the reduction of processing defects can enhance image quality of a sheet of photothermographic imaging material. The prevention of air flow reduces processing defects by maintaining a substantially uniform temperature within a thermal processing compartment of the thermal processor, and by reducing the condensation of fatty acids on interior surfaces of the thermal processing compartment prior to filtration.

International Classification:

G03G 1300
F26B 1310

US Classification:

428 90

Abstract:

An article for cooling an imaging material which has been heated to a first temperature by a thermal processor. The article includes a first cooling section on which the imaging material rides after the imaging material exits the thermal processor. The first cooling section is at a lower temperature than the first temperature. The first cooling section has a curved shape such that the imaging material is curved when riding on and being cooled by the first cooling section.
