6616748, Sep 9, 2003

Filed:

Aug 3, 2001

Appl. No.:

09/922147

Inventors:

Charles P. Klass - Radnor PA
Margaret K. Joyce - Kalamazoo MI

Assignee:

ZO Resources, LLC - San Antonio TX

International Classification:

C04B 1400

US Classification:

106483, 706626, 423700

Abstract:

A high performance purified natural zeolite pigment composition for use in papermaking and paper coating is disclosed. Use of the pigment facilitates manufacture of coated ink jet and digital printing papers with improved quality and economics. The novel zeolite pigment composition can also be used as a supplementary pigment to improve the properties of coated paper and paperboard for flexographic and water-based gravure printing. When used as filler, the novel zeolite pigment composition is readily retained and eliminates print-through in uncoated papers. The novel zeolite pigment is low in abrasion and provides improved coefficient of friction. The novel zeolite pigment is also useful as a microparticulate retention aid in papermaking and as an additive to improve the performance of deinking processes.

Filed:

Feb 19, 2003

Appl. No.:

10/369298

Inventors:

Margaret K. Joyce - Kalamazoo MI, US
Thomas W. Joyce - Kalamazoo MI, US

Assignee:

The Board of Trustees of Western Michigan University - Kalamazoo MI

International Classification:

B05D003/12

US Classification:

427365, 427391

Abstract:

A nanoparticle barrier-coated substrate is prepared by mixing pigment nanoparticles, a binder and a liquid carrier to form a coating solution, applying the coating solution onto the substrate and drying the coating solution to form the barrier coating on the substrate. The pigment nanoparticles can be chosen from talc, calcium carbonate, clay, silica and plastic and the substrate can be a cellulosic material or an inorganic material. If the substrate is initially provided with large pores, a precoating can be applied to the substrate prior to the application of the pigment nanoparticles thereto.

US Classification:

347102, 101491

Abstract:

A method and system for improving the electrical conductivity of a conductive ink trace pattern provided on a substrate involves the printing of a conductive ink on a substrate to form a trace pattern thereon, fixing the trace pattern to the substrate and performing calendering on the substrate having the trace pattern fixed thereto.

Assignee:

Syn-Chem, Inc. - Raleigh NC

International Classification:

C08L 504

US Classification:

106189

Abstract:

Water soluble alginates are prepared as highly concentrated pumpable suspension in mixtures of propylene glycol and water using hydroxypropylated guar gum in combination with carboxymethylated cellulose as a suspending agent. The total composition of hydroxypropylated guar is preferably between about 0. 2 and 5%, suspending between about 15% and 35% alginate.

Abstract:

A method of producing and repulping paper having a silicone release liner includes producing paper having a silicone release liner that is initially secured to the paper by a dissolvable material. During production of the paper, a water-soluble coating may be applied to a paper surface, and a silicone release coating is then applied to the water-soluble coating. Upon rewetting of the paper during repulping, the water-soluble coating dissolves, thereby enabling separation of the silicone release coating from the paper. The repulpable silicone release liner permits recovery of paper fibers using conventional repulping and recycling processes.

Abstract:

A method of producing a printed electronic device on a thin PDMS film which includes coupling a first layer of a water-soluble polymer to a substrate and drying the first layer of the water-soluble polymer. The method further includes coupling a second layer of a crosslinkable PDMS polymer to the first layer of the water-soluble polymer and curing the second layer of the crosslinkable PDMS polymer to form the thin PDMS film. The method also includes printing one or more functional layers on the thin PDMS film and drying the one or more functional layers on the thin PDMS film to form the printed electronic device coupled to the substrate.

A42B 3/12

Abstract:

An impact sensing system includes a first impact sensor having a flexible dielectric layer, a first printed electrode on a first side of the layer, and a second printed electrode on a second side of the layer. The second printed electrode overlies and is moveable toward and away from the first electrode by deformation of the flexible dielectric layer. Further, the layer maintains a capacitance between to the first electrode and the second electrode that changes with a movement of the second electrode toward or away from the first electrode. The system further includes a first readout circuit electronically coupled with the first and second electrodes to measure a change in the capacitance and output a corresponding voltage.
