Abstract: Recyclable and repulpable coated paper stock, preferably for use as ream wrap, comprising a substrate coated on at least one surface with a base coat and at least one additional coat over said base coat. Both coats are water based dispersions of a polymer selected from the group consisting of acrylic polymers, acrylic copolymers, polyvinyl acetate, polyvinyl alcohol, ethylene-vinyl acetate, polyvinyl chloride, styrene butadiene copolymers, polyvinylidiene chloride and its copolymers, or starch. The wax free coating forms a pin-hole free continuous film on the substrate which is resistant to water and water vapor. The invention also includes processes for making and recycling the invented coated paper stocks.

Abstract: There is described a method of preparing water-less lithographic plate which comprises imagewise exposing a lithographic plate coated with a photosensitive composition, processing the exposed plate in an aqueous based developing liquid to remove those areas of the photosensitive composition which are removable by the developing liquid, drying the plate and coating the plate with an ink releasing coating composition which adheres to those areas of the plate from which the photosensitive composition has been removed, but which does not adhere to those areas of the plate from which the photosensitive composition which has not been removed, further treating the plate to cure or fix the ink-releasing composition thus providing ink-receptive areas of the plate which are those areas of the plate from which the photosensitive composition which has not been removed in the developing liquid and ink-releasing areas of the plate which are covered with the cured ink-releasing composition.

Abstract: A system for monitoring of a product quality variable of a moving web produced by associated equipment defines cross-direction (CD) data increments across a width of the web and machine direction (MD) data increments over a running length of the web, and takes CD/MD measurements of the selected variable in order to fill the corresponding CD/MD measurement data boxes and generate a time-dependent two-dimensional array mapping representing the moving web. In the preferred system, the CD data increments are divided across the width of the web, and the MD data increments are time-divided intervals of the time period of an element of the production equipment, so as to produce a time-synchronous array mapping which shows the impact of the periodicity of the machine element on the product quality variable.

Abstract: Coated paper stocks for electrostatic imaging comprising a substrate coated on at least one surface with a resin layer comprised of olefinic material and a pin-hole free, continuous coating layer over said resin layer. The continuous layer has a glass transition temperature above 100.degree. C. and is comprised of one or more natural or synthetic film forming polymers. As a single layer this continuous coating layer functions as both a heat protective and imaging layer. In an alternate embodiment two separate coating layers are provided with separate heat protective and imaging functionalities.

Abstract: An improved fabric hydroenhancement method provides for inducing turbulence in a fluid flow in a hydroenhancing manifold and applying the turbulent fluid flow to impinge on a row of orifices of a jet strip in a manifold, such that jet streams issuing from the jet orifices at an output end of the manifold are formed with a constant state of fluctuation in their cross-sectional shape, direction, and structure. This results in the jet streams distributing their delivered energy over constantly changing impact areas on the fabric, whereby more of the delivered energy is converted into enhancement energy for hydroenhancing the fabric. The turbulent hydroenhancing method is also found to obtain a significant reduction in fabric shrinkage, and also eliminates the generation of interference patterns in the fabric. Turbulence is induced by positioning a baffle below the distribution element in the manifold with its lower end in close proximity to the row of jet orifices. Various types of baffle designs may be used.

Abstract: A nonwoven composite web suitable for use as a battery separator is formed by a wet process on a papermaking machine. The nonwoven composite material is made from a furnish of nylon binder fibers and nylon staple fibers. The web coming off the papermaking machine is dried using infra-red dryers followed by heated dryer cans. After drying, the web is thermally bonded using heated calendar rolls. The nylon binder fibers melt as the web passes through the calendar rolls and thermally bond the nylon staple fibers of the web when the melted binder fiber material fuses upon cooling. The use of dryer cans to dry and partially bond the web eliminates the need for surfactant treatment to improve potassium hydroxide absorption.

Abstract: A recording sheet for ink jet printing comprising a support having coated onto said support one or more layers receptive for aqueous inks, said coating comprising at least one film forming, hydrophilic polymer or a mixture of film forming hydrophilic polymers and imbedded in this film at least one trivalent salt of a metal of the Group IIIb series of the periodic table of elements or complexes which comprise trivalent ions of the metals of Group IIIb of the periodic table of the elements. In another embodiment the salts or complexes of Group IIIb elements are coated directly on the substrate surface without the presence of the film forming polymer.

Abstract: A method of making a light sensitive printing plate such as might be used in lithography, comprises creating a surface layer on substrate base material by depositing particulate coating material on the base material using a dry deposition technique, the surface layer being formed from particles whose size is less than about 15 .mu.m, and creating an image layer on the deposited surface layer so that the surface layer is located intermediate the base material and the image layers.

Abstract: Recycling of mixed wastepaper, including plastic coated paper and printed paper, is accomplished by repulping the wastepaper mixture to disperse paper fibers, ink and plastic components into a pulp medium. Contact with a deinking chemical causes attraction between the ink components to form larger ink particles. The ink is adsorped onto the plastic components to form ink/plastic clusters which are removed to produce a substantially ink and plastic free pulp medium. Recycled paper products with improved strength comprising paper fibers from pulp medium produced in accordance with the method of the invention are also provided.
