Patent number: 6576364Abstract: Printed electrochemical cells including both power cells and display cells are arranged in a partially assembled condition to extend shelf life of the cells. The partially assembled condition is also used as a switching mechanism for controlling activation of some of the cells. The active components of the cells include two electrodes and an electrolyte layer that is maintained out of contact with at least one of the electrodes for interrupting an ionically conductive pathway between the electrodes. The electrolyte is preferably an electrolytic adhesive that is protected by a release layer until the cells are needed for service.Type: GrantFiled: October 6, 2000Date of Patent: June 10, 2003Assignee: Wisconsin Label CorporationInventors: Chauncey T. Mitchell, Jr., David M. Good, Robert Parker, Mark A. Shadle, Gerrit L. Verschuur

Patent number: 6543808Abstract: An improved construction for pull-tab game pieces involves the use or two or more substrates, one of which is at least partially transparent. A thermosensitive imaging layer within which game results are direct thermally printed is located between the transparent substrate and an opaque cover layer through which the game results are printed. An opaque substrate precut to form one or more tabs covers the opposite side of the transparent substrate. The game results are revealed by retracting the tabs to view the game results through the transparent substrate.Type: GrantFiled: July 5, 2001Date of Patent: April 8, 2003Assignee: Translucent Technologies, LLCInventors: Chauncey T. Mitchell, Jr., Daniel R. Fulwiler

Patent number: 6243192Abstract: Printed electrochemical display cells are arranged in layer form with two electrode layers and an electrolyte layer occupying distinct areas of a substrate. When activated, an electrochemical reaction progressively increases the area occupied by the electrolyte layer and progressively decreases the area occupied by the thin-film electrode layer. The thin-film electrode layer recedes at a boundary in common with the electrolyte layer and provides an irreversible indication of change at a rate governed by the electrochemical reaction.Type: GrantFiled: July 26, 1999Date of Patent: June 5, 2001Assignee: Timer Technologies, LLCInventors: Chauncey T.

Patent number: 6124236Abstract: A new direct thermal printable media includes an optically transmissive film that gives both form and protection to a layer of thermosensitive imaging material on a back surface of the film. Concentrations of heat applied to a front surface of the film form images within the thermosensitive layer that are visible through the film. A substrate is laminated to the thermosensitive layer on the back surface of the film for providing additional support independently of physical and chemical properties required for directly supporting thermosensitive imaging material.Type: GrantFiled: September 22, 1997Date of Patent: September 26, 2000Assignee: Media Solutions, Inc.Inventor: Chauncey T.

Patent number: 5930023Abstract: Printed electrochemical display cells are arranged in layer form with two electrode layers and an electrolyte layer occupying distinct areas of a substrate. An electrolyte layer overlaps most of one electrode layer but contacts a smaller portion of the other electrode layer, which is made of a thin film. When activated, an electrochemical reaction progressively increases the area occupied by the electrolyte layer and progressively decreases the area occupied by the thin-film electrode layer. The thin-film electrode layer recedes at a boundary in common with the electrolyte layer and provides an irreversible indication of change at a rate governed by the electrochemical reaction.Type: GrantFiled: April 27, 1998Date of Patent: July 27, 1999Assignee: Wisconsin Label CorporationInventors: Chauncey T.

Patent number: 5912759Abstract: An electrochemical display cell has a layered construction including two electrode layers separated by a dielectric layer. Concentric openings are formed in the dielectric layer and one of the electrode layers exposing a designated portion of the other electrode layer. An electrolyte layer overlaps the one electrode layer and the designated portion of the other electrode layer. When activated, current flow cascades through the openings in the one electrode layer and the dielectric layer to the designated portion of the other electrode layer supporting an electrochemical reaction that erodes the designated portion revealing underlying visual information.Type: GrantFiled: April 27, 1998Date of Patent: June 15, 1999Assignee: Wisconsin Label CorporationInventors: David M. Good, Mark A. Shadle, Gerrit L. Verschuur, Chauncey T. Mitchell, Jr., Robert Parker

Patent number: 5811792Abstract: The contents of sealed envelopes are accessed using radiation to differentially heat information patterns within the contents and conduction to transfer corresponding thermal patterns to the envelopes' outer surfaces. The radiation is preferably within the wavelengths of microwaves or radio waves for penetrating the envelopes. The information pattern differentially absorbs the radiation by converting the attendant radiant energy into heat by either induction heating or dielectric heating. An infrared camera or other thermally sensitive device converts the thermal patterns conducted to the envelopes' outer surfaces into corresponding electrical patterns for further processing.Type: GrantFiled: January 2, 1997Date of Patent: September 22, 1998Assignee: Wisconsin Label CorporationInventors: Gerrit L. Verschuur, Chauncey T. Mitchell, Jr.

Patent number: 5747103Abstract: A printing station conveys a supply of molten lithium from a heated tank to a nozzle within a protective shroud. A web traverses a chiller also within the shroud. The nozzle dispenses discrete amounts of the molten lithium onto successive portions of the web in contact with the chiller. The chilled lithium solidifies into solid lithium patterns. A sealer also within the shroud prevents exposure of the solid lithium patterns to ambient air. The station can be incorporated into an in-line press for forming a succession of electrochemical cells.Type: GrantFiled: April 10, 1997Date of Patent: May 5, 1998Assignee: Voxcom, Inc.Inventors: Chauncey T. Mitchell, Jr., David M. Good, Mark A. Shadle, Gerrit L. Verschuur

The face stock has a front face for receiving thermal transfer ink and a back face covered by an adhesive. The ribbon has a front face covered by thermal transfer ink and a back face covered by a release. The facestock and ribbon are laminated and wound together into a roll so that the ribbon also functions as a conventional release liner.Type: GrantFiled: August 5, 1996Date of Patent: April 14, 1998Assignee: Media Solutions, Inc.Inventor: Chauncey T.

Patent number: 5661099Abstract: A self-wound label stock includes a thermal paper substrate. One face of the substrate is coated with a primer layer having ultraviolet light blockers and a release layer having a smooth surface finish. Another face of the substrate is coated with an adhesive layer. Non-thermal printing is applied between the substrate and the primer layer. Thermal printing is applied to the substrate through the primer and release layers. A separator divides the label stock into individual labels.Type: GrantFiled: August 4, 1995Date of Patent: August 26, 1997Assignee: Media Solutions, Inc.Inventor: Chauncey T. Mitchell, Jr.

Patent number: 5658661Abstract: A direct thermal printable facestock has an adhesive-coated back surface and a release coat applied over a layer of thermal imaging material on a front surface so the facestock can be wound and unwound without using a separate release liner. The release coat is composed of two release agents. One of the release agents is a solid such as tetrafluoroethylene ground into specifically sized particles, and the other release agent is a curable liquid such as silicone within which the particles of the solid release agent are embedded for mechanically cleaning the thermal print head.Type: GrantFiled: August 29, 1995Date of Patent: August 19, 1997Assignee: Media Solutions, Inc.Inventors: Chauncey T. Mitchell, Jr., James T. Wittig, Jr.
