  • Patent number: 10010233
    Abstract: A cleaning pad structure of stitch bonded construction incorporating one or more substrate layers of an absorbent nonwoven material with an optional additional fluid blocking substrate layer of polymer film or other suitable material in juxtaposed relation to the absorbent nonwoven layers. Stitching yarns are introduced in stitching relation through the substrate layers. One face of the pad defines a cleaning surface of raised yarn loops formed by the stitched yarns. The pad further includes an attachment surface facing away from the cleaning surface. The stitches of yarns across the attachment surface define an engagement surface for attachment to cooperating hooking elements across a surface of a mop head to define a hook and loop attachment system.

  • Patent number: 9845406
    Abstract: This invention relates to a coating comprising prepolymer and monomers for application onto polyurethane for chemical resistance, abrasion resistance, water proof etc. Usually polyurethane is porous and does not have sufficient stain, abrasion and chemical resistance. The said coatings developed using technology of chemical grafting that involves the use of prepolymers, monomers, catalyst, graft initiator, wetting agents, fillers and other ingredients of the composition. The coating thus obtained when applied on the polyurethane allows obtaining graft polymerization, thereby forming a polymeric film chemically attached to the substrate. The polyurethane substrate is reacted with graft initiator which creates the reaction sites on the substrate via free radical mechanism.

  • Patent number: 5879758
    Abstract: An improved method for manufacture of coated fiber material, for example a composite fly fishing line, is disclosed. The method includes coating fiber of a first material with a hot melt adhesive material. For fly lines, indices of refraction of the materials are preferably selected so that the finished product is substantially transparent absent addition of pigment. The coated fiber material is exposed to electron beam treatment to improve the physical profile of the coating.

  • Patent number: 5858514
    Abstract: A method and related compositions for preparing a substrate for printing are described. The invention comprises coating a non-paper substrate with an adherent base coat and a hydrophilic top coat. The base coat adheres to the substrate and the top coat, which is applied to the base coat and adheres to it, provides an ink receptive surface on which ink pigment can be deposited. A base coating composition comprises a type-A gelatin and an acrylic polymer. A top coating composition comprises a type-A or type-B gelatin and a hydrophilic organic polymer. A base- and top-coated substrate of the invention is particularly suited for use with ink-jet printers that employ aqueous-based inks. Printing substrates include such materials as canvas, leather, polymeric films and sheets, and the like.

  • Patent number: 5817272
    Abstract: A process of making a biocampatible porous hollow fiber that is made of polyolefine material and is coated with a biocompatible carbon material is disclosed. The biocompatible hollow fiber produced can be used as exchange material, diaphragms and/or semipermeable membranes within devices which will contact blood or plasma outside of the living body. The coated fiber is produced by introducing a preformed porous hollow fiber into an atmosphere of gaseous monomer vinylidene chloride and subsequent induction, e.g. by gamma radiation, of a graft-polymerization reaction to form an uniform polyvinylidene chloride layer. The ultimate coating is formed after a dehydrochlorination reaction in which hydrogen chloride is removed from the layer. The dechlorination reaction is typically performed by treating the fiber with hot concentrated aqueous ammonia solution. The reaction can be continued to reduce the chlorine content of the coating to less than 6% of its original value.

  • Patent number: 5759636
    Abstract: A method for forming electrographic imaging elements comprising a uniform dielectric layer is disclosed. The method comprises coating a conductive coating composition containing polymerizable precursors onto a base, curing the composition to form a conductive layer, and coating a dielectric layer on top of the conductive layer. The elements can be used to produce images have higher image density, reduced background, reduced grain, reduced mottle, reduced overtoning, and greater small-scale uniformity than comparable images formed on electrographic imaging elements produced by other methods. The elements are particularly useful for forming large size colored images, such as are required for posters, displays, other indoor advertising.

  • Patent number: 5679719
    Abstract: Resin compositions useful for filament winding applications comprising an epoxy component including at least one polyepoxide resin curable by heat, an olefinicially unsaturated monomer component including at least one polyolefinically unsaturated monomer curable by actinic radiation, at least one photoinitiator which is not a peroxide, at least one organic peroxide, and a heat activated curing agent for epoxides. The compositions have a viscosity less than about 2000 centipoise (cps) and are capable of retaining this viscosity for at least about 2 hours at a temperature of from about ambient temperature to about 60.degree. C. The resins are capable of being immobilized by actinic radiation exposure and further heat cured without substantial resin drip. One or more organic peroxides are employed, selected from the group of organic peroxides having 10 hour decomposition half lives at temperatures of from about 50.degree. C. to less than about 104.degree. C.

  • Patent number: H1631
    Abstract: The present invention is a method for making radar chaff consisting of metal rings having varying diameters, using photolithographic processes. One aspect of the invention has the steps of: providing a metal foil having a thickness suitable for use in radar chaff; overcoating the metal foil with a photoresist, to form a layered structure; undercoating the metal foil with a removable backing; exposing the photoresist to a quantity of actinic radiation for chemically modifying the photoresist into a photoproduct suitable for subsequent development, where the actinic radiation is patterned into a series of concentric rings; developing the photoresist, to expose the underlying metal in a series of concentric rings; removing the exposed metal to form a series of concentric metal rings on the removable backing; and removing the removable backing. Another aspect of the invention is a metal chaff precursor, comprising: a removable backing, coated with a plurality of concentric metal foil rings.
