H05C 100

US Classification:

435 6

Abstract:

Provided is a method of fabricating a substrate having on a surface thereof two or more spatially-resolved regions, each with a defined amount or concentration of one of one or more chemical components, the method comprising: associating a chemical component with particles of 1. mu. m to 500. mu. m diameter; electrostatically depositing the particles on the appropriate regions; and if a said spatially-resolved region is to receive a second chemical component, repeating steps (a) and (b) for that chemical component and the appropriate regions.

Assignee:

Polypure, Inc. - Solvay NY

International Classification:

C08F 830

US Classification:

525379

Abstract:

Novel cationic polymers are provided by reaction of high molecular weight polymers and copolymers of acrylamide with an alkyl epoxide compound such as glycidyldialkylamine or glycidyltrialkylammonium salt to form polymer chain units containing e. g. pendant (N-2-hydroxypropyl) dialkylamine groups of their trialkylammonium salts. Processes for making the graft copolymers are provided in which the reaction is carried out while maintaining the reaction mixture in gel form by swelling the starting solid polymer with a solvent mixture. The reaction may be carried out in a homogeneous reaction environment or in a heterogeneous reaction environment by dispersing the starting solid polymer in an inert liquid that is a non-solvent for both the polymer and the salt. The polymeric products of the reaction may be hardened with a suitable liquid, such as isopropanol, to a solid particulate material.

Abstract:

A display as for images and/or information comprises a plurality of light-emitting fibers disposed in side-by-side arrangement to define a viewing surface. Each light-emitting fiber includes a plurality of light-emitting elements disposed along its length, each having two electrodes between which are applied electrical signals to cause the light-emitting element to emit light to display a pixel or sub-pixel of the image and/or information. The light-emitting fiber includes an electrical conductor disposed along its length to serve as a first electrode, a layer of light-emissive material disposed thereon, and a plurality of electrical contacts disposed on the light-emissive material to serve as the second electrodes of the light-emitting elements. Preferably, the conductors, light-emissive layer and plurality of electrical contacts are formed in a continuous process wherein a transparent fiber passes through a plurality of processing chambers for receiving the electrical conductor, the light-emissive layer and the plurality of electrical contacts thereon.
