Diffusion or sublimation transfer imaging system

Abstract: Images can be formed on a receptor sheet by transfer of a dye image. The positive dye image is formed by bleaching of dye with an iodonium ion. The positive dye image is then transferred by sublimation or diffusion onto a receptor sheet.

High brightness internal reflector for liquid crystal displays and its method of fabrication

Abstract: A reflector for use in liquid crystal displays is disclosed comprising a plate having a micro-lenticular surface over which are successive layers of reflective material, such as aluminum or silver and a light transparent material having a low index of refraction, i.e., an inex of refraction below that of SiO2, which is in optical contact with the reflective layer. The present invention also contemplates the method of fabricating such a reflective surface.

Vibration-damping constrained-layer constructions

Abstract: A constrained-layer construction comprising a stiff layer or substrate and a layer of a viscoelastic polymer which is the reaction product of (a) 25 to 75 weight percent of an acryloyl or methacryloyl derivative of at least one oligomer, said oligomer having a glass transition temperature of less than 25° C. and a molecular weight per oligomer of 600 to 20,000, and (b) 75 to 25 weight percent of a copolymerizable monomer whose homopolymer has a glass transition temperature of at least 50° C., the copolymer being suitable for damping vibrations at relatively high temperatures, e.g., 50°-150° C., is disclosed. Also included is a process for damping vibrations in component parts of devices used in automotive, aerospace, and computer industries.

Hydroalcoholic compositions for transdermal penetration of pharmaceutical agents

Abstract: Hydroalcoholic compositions useful for the enhancement of the transdermal delivery of a pharmaceutical agent, methods of preparation, transdermal delivery systems, and methods of delivering the pharmaceutical agent are provided. The composition includes a lower alcohol and water in a weight ratio of at least about 20:80, a pharmaceutical agent, and an emulsifier system.

Liquid inks using a controlled crystallinity organosol

Abstract: A liquid ink composition containing organosols having side-chain or main-chain crystallizable polymeric moieties is described. The incorporation of organosols having crystallizable polymeric moieties into the ink compositions provide improved blocking resistance and improved erasure resistance when used in ink transfer, ionographic, electrographic and electrophotographic color printing or proofing processes.
