Abstract: An anti-marking covering for use on a printing press transfer cylinder to prevent ink marking of printed sheets is made of a material having a high axial air permeability through the material parallel to its surface and a substantially uniform surface structure free of raised areas. A preferred material is 100% rayon hydroentangled nonwoven fabric subjected to comb-roll microcreped compressive forming of microcreped areas closely spaced about 1/16 inch apart. The preferred fabric has an axial air permeability of about 0.279 cfm. When the material is wrapped tightly onto a press cylinder, the high axial air permeability allows an air layer to be maintained under the printed sheets, and the uniform surface structure is free of high points that might protrude through the air layer and contact the printed sheets. Other fabrics and materials suitable for the anti-marking covering include woven and knitted fabrics, nonwoven fabrics, and open-celled foam.

Abstract: Recyclable and compostable coated paper stock comprising a substrate coated on at least one surface with a primer coat and a top coat both of which are water based dispersions. The primer coat comprises a water based dispersion of a polymer selected from the group comprising acrylic polymers, acrylic copolymers, polyvinyl acetate, polyvinyl alcohol, poly-ethylene vinyl acetate, poly-ethylene vinyl chloride, styrene butadiene copolymers, polyvinylidiene chloride or starch. The top coat comprises a water based dispersion of a polymer selected from the group comprising acrylic polymers, acrylic copolymers, styrene butadiene copolymers or polyvinylidiene chloride. In another embodiment the top coat further includes a wax component comprising 15-90 wt. % of the polymer and 5-85 wt. % of the wax. The substrate is coated with a primer coat prior to the application of the top coat to seal the substrate surface.

Abstract: An apertured nonwoven fabric comprising one or two outer carded web(s) and a polymeric sheet thermally bonded thereto. The polymeric sheet has a lower melting temperature than the nonwoven layers and a property of shrinking when melted. Heat and pressure are applied to the combination of layers through a calender roll such that the polymeric sheet becomes bonded to the fibers of the carded web(s) and simultaneously shrinks and pulls back the fibers away from the calendering points, thereby generating apertures through the nonwoven fabric. Preferably, the fibers are polyethylene or polypropylene fibers, and the polymeric sheet is a thin plastic film of linear low density polyethylene, elastomeric, or heat shrink material. One outer carded web may be combined with the plastic film layer to form a bi-laminate product, or two outer carded webs may be combined with an intermediate plastic film to form a tri-laminate product.

Abstract: The present invention relates to a novel composite product which is composed of a fibrocrystalline heterogeneous structure consisting of:on the one hand a plurality of fibers of expanded specific surface area and of hydrophilic character, having a substantial quantity of microfibrils on their surface, andon the other hand crystals of precipitated calcium carbonate (PCC), organized essentially in clusters of granules, the majority of which trap the microfibrils and are joined directly thereto by mechanical bonding.Application to the field of construction materials and papermaking.

Abstract: There is described a new magenta azo dye which can be used in an aqueous composition in an ink-jet printing process.

Abstract: Topical gel and cream formulations containing human plasma fibronectin and other wound healing promoters are used for the healing of cutaneous wounds. The formulations provide slow release and increased contact time of fibronectin and of other wound healing promoters to the wound site leading to the effective absorption of the promoters.

Abstract: There is described a method of processing silver halide photographic material in a processing machine using a developing solution which comprises either a hydroquinone type developing agent or a reductone type developing agent, together with an electron transfer agent as an auxiliary developing agent, and with at least one basic compound the anion of which is carbonate, sulphite or hydroxide, where in the presence of a compound of formula (I), Ar is an aromatic ring or heterocyclic aromatic ring which is optionally substituted.

Abstract: A pressure screening system for processing contaminated pulp fiber including a pressure screen apparatus for separating an accepts stream of clean fiber from a rejects stream carrying contaminants, and a feed tank for supplying a pulp fiber slurry to the inlet of the pressure screen apparatus, wherein the feed tank has a flotation section for receiving the rejects stream together with air for generating a froth separating a rejects overflow of contaminants from the remainder of the feed stock for recovery of additional pulp fiber from the rejects stream. The air may be contained in the rejects stream when it enters the flotation section, or it may be introduced at or near the input to the flotation section. The feed tank with flotation section can receive the rejects streams from multiple pressure screen stages, or a separate feed tank can be used for each pressure screen stage.

Abstract: An ink vehicle composition is provided comprising a polymeric type resin binder component and a terpene dimer oil. In an alternate embodiment the compositions further include an additional oil selected from linseed oil, soya bean oil, tung oil, or other oils having drying characteristics defined by an Iodine value greater than 120. Advantageously, the compositions contain a reduced amount of petroleum distillate solvent and lower volatile organic compounds (VOC) than conventional ink vehicles. As an ink vehicle the compositions are further incorporated into ink formulations. The varnish compositions are also used as an overprint varnish on a substrate surface.

Abstract: An adaptor for use in a video microscope system including a video monitor, a camera and a microscope. The adaptor comprises a hollow body portion including open top and bottom ends, said body portion having an interior surface; first means for coupling said top end to the camera; and second means for coupling said bottom end to the microscope. The microscope includes a base portion having a top surface opening and objective lens; wherein the bottom end of the adaptor is coupled to the top surface opening of the microscope. The adaptor transmits light directly from the objective lens to the camera without changing the direction of the light. The adaptor fits conventional and infinity corrected microscopes to convert the microscopes into dedicated video microscope systems. The video monitor is connected to the system to provide presentation of microscope object images to a group of observers. The system may additionally be interfaced with a computer system to add text and save images.
