Abstract: This invention provides an article having an alteration-sensitive surface, generally a sheet material formed of spun continuous strands of fine interconnected fibres of polyolefin, which are bonded together with heat and pressure. The surface of the sheet material is degraded by utilizing solvents, prior to imprinting desired information onto the surface, the surface then being easily abraded so as to substantially prevent alteration without permanently changing the appearance of the surface. Preferably, the surface of the sheet material is overall coated, or imprinted, with a contrasting color such that by abrading the surface the imprint is erased and the white or other natural color of the olefin fibres appears, thus increasing the visibility of the abraded surface.

Abstract: The method for making patterned resist masks having minimum opening dimensions. The mask is prepared initially using standard photo or electron beam lithography techniques to yield the smallest aperture dimensions consistent with the state-of-the-art. Then, the resulting mask is placed within a chamber containing an atmosphere of resist solvent vapor. The vapor is absorbed by the patterned resist mask causing controlled resist reflow which uniformly reduces the dimensions of the resist openings by an amount determined by time, temperature, resist thickness, resist type and solvent used.

Abstract: In the flow coating of inverted metal cans, an unhardened bead of excess coating material at the lower edge of the can is removed in a thinner bath through which the can is passed while hanging suspended from a conveyor. The thinner dissolves the bead and removes the coating on the lower edge of the can. The conveyor lifts the can out of the pool on a gradually rising path with the can hanging essentially vertical. Unhardened coating on the can sidewall above the area from which it has been removed, flows down and recoats the lower edge essentially uniformly but not to excessive thickness.

Abstract: Iridescent pigments, of the type which comprise colorless micaceous substrates having thereon at least one overcoating of an essentially transparent material with a refractive index over about 2.0, can be enhanced in coloration by applying to them a solution of a coloring matter which possesses an absorption band complementary to the interference reflection color of the pigment, and which thereby absorbs that complementary color. The resulting vivid intensity of the iridescent coloration is far out of proportion to the concentration of the coloring matter and to the intensity of the absorption band. The enhanced colors are useful in novel colorants, printing inks, recording systems, and copy papers.

Abstract: A process for treating a steel surface, comprising the steps of immersing the surface in a bath of molten tin at a temperature and for a period of time suitable to cause a layer of tin containing diffused iron to adhere to the surface and, after removal of the surface from the bath, removing a surface layer in which iron and tin accord substantially with the formula of Fe Sn.sub.2 so as to expose a layer in which iron and tin accord substantially to the formula Fe Sn.

Abstract: Iridescent pigments, of the type which comprise colorless micaceous substrates having thereon at least one overcoating of an essentially transparent material with a refractive index usually over about 2.0, can be enhanced in coloration by applying to them a solution of a coloring matter which possesses an absorption band complementary to the interference reflection color of the pigment, and which thereby absorbs that complementary color. The resulting vivid intensity of the iridescent coloration is far out of proportion to the concentration of the coloring matter and to the intensity of the adsorption band. The enhanced colors are useful in novel colorants, printing inks, recording systems, and copy papers.

A liquid humidifying agent is applied to the panel surface which wets the surface of the panel, which is soluble in water, and which reduces the surface tension of the water. Water is also applied to the panel to cause the water to follow the humidifying agent into the panel to increase its moisture content to a desired value.

The surface covering comprises a flexible strip or sheet of substantially dry, semi-hydrated gypsum, bonded to a re-enforcing mesh or lath. The method includes the steps of coating the rear face of the surface covering sheet with aqueous latex adhesive in an amount which will transfer sufficient water from the adhesive to the gypsum to hydrate and set the gypsum, and, at the same time, invert the latex to a tacky, adherent state; and applying the adhesive-coated surface covering to the substrate.

Abstract: A sheet material having a microporous surface of elastomeric polyurethane is treated to produce a sheet, which has greater water-proofness and still transmits water vapor, by applying to it a coagulated layer of elastomeric polyurethane. Preferably the coagulated layer is produced by applying a pigmented polyurethane solution to the sheet while it is wet with a non-solvent. The coagulated layer may then be treated in various ways; e.g. it may be embossed or treated with a solvent to form a fused glossy moisture vapor-transmitting surface. The product is suitable for use as a leather substitute in shoe uppers.
