Abstract: This invention relates to a process for improving the water wicking and moisture transport properties of synthetic resins, e.g., fiber form polyamides, polyesters, polyolefins, and polyacrylonitriles, which comprises sulfofluorinating said resins in a self-activating gaseous reaction medium containing from about 0.1-20% by volume elemental fluorine, 0.1-50% by volume of sulfur dioxide, 0-21% by volume oxygen, and the balance inert for providing from 1 .times. 10.sup.-.sup.9 to 1 .times. 10.sup.-.sup.3 milligrams fluorine and sulfur per square centimeter of resin surface.

Abstract: Reversibly moisture-vapor-absorptive sheet materials and a process for their manufacture in which water-soluble polymers of vinyl ethers are combined with base materials and crosslinked thereon.

Abstract: A process for producing flat sheets, particularly photographic sheets for use in automatic film changing equipment, from a stored roll of material. A thermoplastic film is briefly heated to above its second order transition temperature but not over 120.degree. centigrade prior to cutting for packaging. Such heating removes roll curl developed during storage of the film in rolls, without adversely affecting the quality of the film.

Abstract: Packaging material for ferrous metal parts and the like which comprises a substrate of paper stock, transparent film or foil, and having applied thereon a coating comprehending a vapor phase corrosion inhibitor of the nitrite-amide type, and a self-sealable adhesive as from the natural and synthetic latices. The proportion of the inhibitor to the latices in the coating is in the range from 5 to 25 percent by weight depending upon the characteristics of the substrate.

Abstract: A composition for, as well as a method of bonding gold to a ceramic substrate and a bonded gold article which includes a composition of gold, copper oxide, and cadmium oxide for bonding a gold layer to a ceramic substrate. Gold powder, copper oxide particles and cadmium oxide particles define a solid composition mixture where the copper oxide has a weight percentage in the preferred region between 0.25 and 3.0% and the cadmium oxide has a weight percentage in the preferred region between 1.0 and 5.0%. Organic binder is added to a predetermined amount of the copper oxide and cadmium particles and then blended. The gold powder is incorporated into the copper oxide, cadmium oxide, and organic binder to form a total composition mixture. The organic binder has a weight percentage of the total composition mixture within the ranges of 10 to 95%. The total composition mixture is blended and applied to a ceramic substrate. The coated ceramic article is fired within the preferred temperature range 950.degree. to 100.

Abstract: A Method of coating particulate materials (such as silica sand, glass beads, seeds and metal particles) with a liquid thermosetting epoxy resin which comprises agitating the epoxy resin with the particles in a nonpolar liquid, which is immiscible with the epoxy resin, and contains a nonionic surfactant having a molecular weight of at least 2,000 to retard the tendency of the epoxy coated particles to agglomerate during curing of the resin in the non-polar liquid. A suitable liquid for use as the immiscible liquid is a paraffinic oil which is aromatic-free and olefin-free.

Abstract: A paint film based on a thermo-setting resin which is applied on an aluminum article may be improved in its adhesion properties and resistance to chemical and mechanical attacks as well as in its resistance to weathering, if the surface of the aluminum article is previously anodized to form the oxide surface layer or is treated in boiling water to form the boehmite surface layer and if the oxide surface layer, including the boehmite layer, is pre-treated with a silane compound prior to the application of the coating composition. The application of the paint composition is conducted in this invention by means of a known coating technique such as dipping, spraying, showering, brushing or roller-coating, other than the electro-deposition technique.

Abstract: A method of manifold copying using recording members having a dielectric surface on one side and surface of relatively lower resistivity on the opposite surface, which comprises forming a pack by placing sheet on sheet with the dielectric surfaces facing one way so that each dielectric surface excepting on one outer sheet is in contact with the lower resistivity surface of the next sheet, then placing the pack on a support with the lower resistivity surfaces on each sheet facing the support, then contacting the sheet further removed from the support with pressure imaging means, thereby to form a latent image on each dielectric surface, then separating the sheets of the pack and developing the latent image on each sheet by attracting thereto electroscopic marking particles.
