Solvent-Activated Color Forming Compositions

View page
US Patent:
6680205, Jan 20, 2004
Filed:
Apr 26, 2000
Appl. No.:
09/557733
Inventors:
Joel D. Elhard - Hilliard OH
Richard P. Heggs - Dublin OH
Assignee:
Battelle Memorial Instittue - Columbus OH
International Classification:
G01N 2556
US Classification:
436166, 436169, 422 58, 473378, 73 73
Abstract:
Color-forming compositions comprising (i) a solvent absorbing material such as a polymer; (ii) a color-former or chelating agent compounded with the solvent absorbing material; and (iii) a source of metal ions, whereby the metal ions complex with the color former as the solvent absorbing material absorbs the solvent, resulting in a detectable color change of the solvent absorbing material. Both reversible and irreversible versions of these color-forming compositions are provided.

Solvent-Activated Color-Forming Compositions

US Patent:
6689619, Feb 10, 2004
Filed:
Apr 26, 2001
Appl. No.:
09/843451
Inventors:
Joel D. Elhard - Hilliard OH
Richard P. Heggs - Dublin OH
Assignee:
Battelle Memorial Institute - Columbus OH
International Classification:
G01N 2556
US Classification:
436166, 436169, 422 58, 473378, 73 73
Abstract:
The present invention provides an object, which, in its outer surface contains a color-forming composition which comprises a solvent-absorbing material that is generally a polymer; a color-former compounded with the solvent-absorbing material, where the color-former functions as a metal chelating agent; and metal ions capable of forming a chelate complex with the color-former as the solvent-absorbing material absorbs a solvent, resulting in a detectable color change of the composition. The present invention also provides a method for indicating exposure of the color-forming composition to a solvent, wherein the color-forming composition is to be used on the outside surface of objects.

Plasticizers Derived From Vegetable Oils

US Patent:
6797753, Sep 28, 2004
Filed:
May 4, 2001
Appl. No.:
09/849071
Inventors:
Herman P. Benecke - Columbus OH
Bhima R. Vijayendran - Dublin OH

C08K 51515
US Classification:
524114, 524569, 530232, 544528, 544561, 554149, 554170, 554227
Abstract:
Compositions and methods for plasticizing polyvinyl chloride polymers where the plasticizers contain fatty acids derived from vegetable oils and the fatty acids are substantially fully esterified with an alcohol (monool or polyol), the fatty acids having unsaturated bonds that are substantially fully epoxidized, and wherein the fatty acids are added substantially randomly to one or more hydroxyl sites on the alcohol. The plasticizers may be added in amounts between about 10 to 230 pph of PVC resin.

Patterning Compositions, Masks, And Methods

US Patent:
7626185, Dec 1, 2009
Filed:
Aug 9, 2007
Appl. No.:
11/836481
Inventors:
Stephen J. Krak - Newark OH, US
Joel D Elhard - Hilliard OH, US
Eric L Hogue - Galloway OH, US
Timothy J Stanfield - Lewis Center OH, US
Richard P Heggs - Dublin OH, US
Assignee:
Battelle Memorial Institute - Columbus OH
International Classification:
G03F 9/00
G03F 1/00
G21K 5/10
US Classification:
25049222, 2504922, 430 5, 4302701, 716 21
Abstract:
Electromagnetic radiation sensitive mask materials are provided. The mask materials are chosen such a first percentage of electromagnetic radiation at a first wavelength is transmitted through the mask material prior to the exposure of the mask material to electromagnetic radiation at a second wavelength and a second percentage of electromagnetic radiation at the first wavelength is transmitted through at least a portion of the mask material after the at least a portion of the mask material is exposed to electromagnetic radiation at the second wavelength. Methods of patterning substrates using electromagnetic radiation sensitive mask materials are also provided. Compositions for producing masks are provided, and systems are provided.

Readily Deinkable Toners

View page
US Patent:
7645549, Jan 12, 2010
Filed:
Feb 27, 2004
Appl. No.:
10/546744
Inventors:
Bhima R. Vijayendran - Dublin OH, US
Herman P. Benecke - Columbus OH, US
Elizabeth Drotleff - Worthington OH, US
Joel D. Elhard - Hilliard OH, US
J. David Robbins - Worthington OH, US
Jeffrey Cafmeyer - Columbus OH, US
Joan Muellerleile - Bexley OH, US
Assignee:
Battelle Memorial Institute - Columbus OH
International Classification:
G03G 9/087
US Classification:
4301081, 4301093, 4301371
Abstract:
Broadly the invention provides for a deinkable toner composition, an image made with the deinkable toner, and a method for making the toner including a coloring agent; a thermoplastic polymer; and a protein. In another embodiment the toner includes a coloring agent and a thermoplastic polymer where the protein has been incorporated into the polymer itself. In typical embodiments the protein is derived from soybeans but may be from other plant or animal sources. Typically the toner has a positive triboelectric charge of between about 10 to about 40 microCoulomb/g, or a negative triboelectric charge of between about 10 to about 40 microCoulomb/g.

Abstract:
An electrically conductive coating composition is provided for use on aircraft and other substrate surfaces to prevent the formation of ice or to melt ice. The conductive coating composition may include a nanomaterial such as carbon nanotubes dispersed in a solvent which may be applied to a substrate surface to form a thin film which is resistively heatable. The conductive coating may also comprise a nanomaterial formed from carbon nanotubes or fullerenes grafted to a polymer containing an active functional group which renders a substrate surface icephobic and is also resistively heatable.
