Abstract: In a digital imaging system including an array of imaging devices that apply an image to a recording medium such as a lithographic printing plate, elimination or reduction of longitudinal imaging artifacts is accomplished by blending the zones imaged by each the devices. In the course of a complete scan of the recording medium, the imaging devices each traverse a series of longitudinal columns of dot locations, and the devices are fired only at appropriate dot locations as determined by the digital image data. By operating adjacent imaging devices such that the zones they would ordinarily cover are blended in a random pattern, artifacts at the boundary between zones (such as seams) are hidden. While sufficient visual disruption to eliminate artifacts is ensured, noticeable visual artifacts are not created as a consequence of the disruption.

Abstract: Dimensional inconsistencies between a proof and an image to be overlaid thereon is avoided by subjecting both the proof image and the overlay image to the same heat treatment, thereby ensuring that both images undergo the same degree of shrinkage.

Abstract: A method of inserting a fill yarn on an air jet loom includes propelling a fill yarn with one or more air jets from the insertion side to the exit side of the loom, where the yarn comprises a strand of individual filaments, the strand having a primary cross-sectional shape and periodic flat spots with a flat cross-sectional shape which is more elongated than the primary cross-sectional shape, and where the flat spots provide increased drag for propulsion by the air jets.

Abstract: Disclosed is a coloring agent-containing coating composition comprising a film-forming latex polymer, an epoxy-functional silane, an acid-functional latex polymer, a mercapto-functional silane, and a cationic dye. Such coating compositions are particularly suited for coating onto glass fibers.

Abstract: A coating composition for glass fibers comprising a film former of emulsified clad particles having a core of poly alkyl methacrylates and that include at least 5% of methyl methacrylate and a cladding of a softer thermoplastic polymeric material having a Tg of 10.degree. C or less. A method of producing such emulsified coated particles is also disclosed, as well as glass fibers coated with such mixtures.

Abstract: The disclosure teaches the gelling and thickening of matrix forming resin systems by ion-dipole bonds. Suitable ions are introduced into the resin matrix as alkaline oxides or hydroxides. Thermoplastic polymers containing polar groups are used as additives for the thermosetting resins to offset shrink of the thermosetting resins during their crosslinking and curing in the molding operation. In the molded thermoset state of the resin materials, the polar groups provide sites for the improved bonding of paints, as for example, gel coats. The invention has particular advantages in polyester thermosetting resin systems and in the thermoplastic additives that are used therewith. Polar monomers copolymerized with styrene are the preferred thermoplastic additives.

Abstract: Glass Fibers sized with water soluble polymeric compositions to maintain strand integrity during processing and to induce complete filamentization of the glass fibers from a bundle during blending and mixing of the glass fiber bundle with an aqueous medium.
