Abstract: A coated paper product having high gloss and brightness is prepared by a process wherein a paper substrate is coated on at least one side with an aqueous coating formulation comprising an effective amount of a plastic pigment, and finished in a supercalender device containing heated rolls to produce a surface which is comparable to a cast coated surface.

Abstract: In a tall oil refining operating plant, a warm water loop is disclosed for cooling the tall oil heads fraction extracted from the crude tall oil, rather than the conventional use of cold water. This avoids condensation and the subsequent solidification of athraquinone pulping aid remaining in the crude tall oil; thus, avoiding fouling of the cooling towers. The temperature of the warm-water is controlled automatically by tempering the cold water entering the warm water “cooling” loop, while removing excessively warm water from said loop to the cooling tower system, as needed.

Abstract: This invention relates to a loose draw detector for a paper machine wet press. Such structure of this type, generally, use laser triangulation displacement sensors mounted and positioned to measure the point of web release from the center roll and measure paper web wrinkles in the form of rapid fluctuations/decreases in the standoff distance between sensors and the web passing over the leadout roll to determine loose draw.

Abstract: Phase change (hot melt) ink compositions for use in a phase change (hot melt) ink jet recording device in which recording is conducted by thermally melting the ink at a temperature above ambient temperature (20° C.) to provide prints that possess high quality images, scratch resistance, abrasion resistance, low-temperature storage stability and flexibility, offset and pick resistance, adhesion, and other desired properties are disclosed to comprise: (a) from about 0.1% to about 30% of one or more colorants; and (b) from about 0.1 to about 99.9% of one or more hybrid polymers. Components other than those listed above may be included in the ink compositions to achieve specific printer, substrate, or end use requirements.

Abstract: The present invention comprises an alum/rosin composition for internally sizing paper which is useful in any papermaking furnish with moderate to high hardness, as well as methods for preparing such alum/rosin composition. Employing the invention alum/rosin composition of an alum to rosin ratio of 1-3:1, respectively, and of a mean particle diameter of no greater than 10 microns, results in sizing of improved efficiency. In the preparation of the invention sizing composition, the pre-reacting of either neat or solutions of alum and rosin before introducing the mixture into the papermaking furnish, allows the alum to be free to react with the rosin size without any competition from other cations in the furnish.

Abstract: This invention relates to a laminate substrate. An exemplary embodiment comprises a paperboard layer with a heat sealable layer secured substantially adjacent to one side of the paperboard layer. A co-extruded layer is secured substantially adjacent to the other side of the paperboard layer. The co-extruded layer has five layers: a heat sealable layer secured to the paperboard layer, a first tie layer secured adjacent to the heat sealable layer, a semi-crystalline nylon layer secured adjacent to the first tie layer, a second tie layer secured adjacent to the semi-crystalline nylon layer, and a heat sealable layer secured adjacent to the second tie layer. A fourth heat sealable layer is secured adjacent to the co-extruded layer.

Abstract: This invention relates to novel rosin-fatty acid vinylic polymer compositions which exhibit properties that make them useful for formulating moisture vapor barrier coatings for paper and other cellulosic base materials. In particular, this invention relates to rosin-fatty acid vinylic polymer moisture barrier coatings obtained from the addition polymerization reaction of a mixture of rosin and fatty acid and a mixture of (meth)acrylic and vinylic monomers.

Abstract: The present invention relates to novel hydrocarbon resins and the process for preparing them. In particular, the invention relates to the production of hydrocarbon/acrylic hybrid resins which are suitable for use in formulating adhesives, printing inks, and other coating compositions.

Abstract: This invention relates to an apparatus and method for enhancing extruded polyethylene terephthalate (PET) film adhesion to a cellulosic substrate. Such structures of this type, generally, use specialized primers which are applied in-line on the extruder such that the adhesion of PET to the cellulosic substrate can be greatly increased. This is accomplished by improvement of the chemical bond between the polymer film and substrate/primer.

Abstract: This invention relates to ovenable and dual-ovenable coated paperboard suitable for use in producing food trays. More particularly, the invention relates to paperboard substrates which have been coated with a water-based release coating composition. Food trays made from such paperboard have superior grease resistance, high temperature resistance, and excellent food release properties—characteristics which make these trays particularly suitable for use in baking applications.

Abstract: An adsorptive monolith made by extruding a mixture of activated carbon, a ceramic forming material, a flux material, and water, drying the extruded monolith, and firing the dried monolith at a temperature and for a time period sufficient to react the ceramic material together and form a ceramic matrix. The extrudable mixture may also comprise a wet binder. The monolith has a shape with at least one passage therethrough and desirably has a plurality of passages therethrough to form a honeycomb. The monolith may be dried by vacuum drying, freeze drying, or control humidity drying. The monolith is useful for removing volatile organic compounds and other chemical agents such as ozone from fluid streams. Particularly useful applications include adsorptive filters for removing ozone from xerographic devices and other appropriate office machines and volatile organic compounds from automobile engine air intake systems.

Abstract: A clamshell container for disposable, single-use applications comprising a reinforced positive locking closure that includes an inverted tab closure element located within the front wall of one compartment thereof, and a slot cutout located within the front wall of a corresponding compartment thereof.

Abstract: The moisture application system of the present invention comprises in combination a first means for applying liquid to a paper web and a second means in contact with the web for scraping off excess liquid and spreading the liquid uniformly across the paper web. The moisture application system of the present invention is particularly useful when combined with a machine calender for finishing a paper web.
