Interactive diagnostic and instructional material is recorded on the tape to instruct the operator about the cleaning operation to enable the operator to evaluate progress of the head cleaning operation, and to program the maintenance protocol of head cleaning cycles relative to capstan cleaning cycles.

Abstract: A method and apparatus for applying pressure sensitive adhesive to a substrate, in which the adhesive is deposited on a transfer surface, such as a circulating transfer belt, dried, and subsequently transferred to a plurality of overlapping sheets. The sheets are preferably coated with a primer or a low adhesion backsize, or both, prior to application of the adhesive.

Abstract: A writable matte article comprising a water-absorbing layer coated on a substrate. The water absorbing layer is a unique blend of a crosslinked, water absorbing polymer particle, a water insoluble binder polymer with good adhesion to the film, and optionally, inert organic or inorganic particles that impart a matte finish to the coating. Advantageously, drying times of these inks using the present invention is reduced from about 10 minutes to 10 seconds. Preferred films are polyester and polyolefin-based films.

Abstract: An adjustable mounting system for premetered contact coating dies includes a base and a die-receiving portion movably connected to the base. During coating, the die can float a distance from the surface being coated based on the balance of forces between the die and the coated surface. This creates a variable separation gap and allows automatic self-compensating for variations in web or fluid properties. This, in turn, optimizes the coating characteristics. The mounting system can also include an enclosure for protecting its components.

Abstract: An energy sensitive composition comprising a monomeric organometallic complex essentially free of nucleophilic groups and which, upon exposure to energy, bonds to basic reactive sites on a substrate via the metal center, leaving the polymerizable group of the complex unreacted and unrestricted; an energy sensitive composition at least one energy sensitive organometallic group is incorporated in or appended to the backbone of a polymer, such that the resulting coordinatively unsaturated organometallic group or groups bond to basic reactive sites on a substrate, thus forming permanent bonds, and further, the adherent compositions are useful in applications such as adhesion of polymers to substrates, protective coatings, printing plates, durable release coatings, primers, binders, and paints.

Abstract: The present invention provides a method for the formation of an organic coating on a substrate. The method includes: providing a substrate in a vacuum; providing at least one vaporized organic material comprising at least one component from at least one source, wherein the vaporized organic material is capable of condensing in a vacuum of less than about 130 Pa; providing a plasma 10 from at least one source other than the source of the vaporized organic material; directing the vaporized organic material and the plasma toward the substrate; and causing the vaporized organic material to condense and polymerize on the substrate in the presence of the plasma to form an organic coating.

Abstract: The adhesive of this invention comprises of a combination of an anionic sulfonated polyester urethane dispersion, an acrylic/vinyl polyester urethane dispersion, a non-sulfonated polyester urethane dispersion, solvents and a rheology modifier combination capable of producing a cobweb type pattern while maintaining a uniform dispersion of the aforementioned materials.

Abstract: An electrochemical cell for the production of fluorine includes an anode having a carbon portion partially or fully impregnated with a polymeric material and a conductive centrally disposed internal channel that permits the anode to be run at high current with uniform current densities without undue resistance heating.

Abstract: Abrasive articles are provided having at least one of a backing material saturated with a saturant, a barrier coat, a make coat, a size coat layer or combinations thereof wherein the saturant and layers consisting essentially of 100% solids radiation-cured resin of one or more vinyl ether monomers and/or oligomers.

Abstract: A sheet material for mounting on a substrate such as a wall, and displaying an article such as a greeting card, comprising a film backing, a first repositionable adhesive coating on one surface, and a second repositionable coating on the other surface. The sheet material permits the article to be adhered to, repositioned on, and removed from the sheet material without removing the sheet material from the substrate to which it has been adhered.

Abstract: Sheets to be coated with water-based coating material, for example a primer and a low adhesion backsize, are supplied from a feeder (1), in end-to-end overlapping relationship, to a dual coater (3) in which the sheets are coated individually on both sides. A sheet inserter (2) is provided, upstream of the dual coater, to insert sheets from a second supply into the sheets from the feeder (1). The dual coated sheets are dried as individual sheets or as a pseudo-web of overlapped sheets, The sheets are then overlapped, unless previously overlapped, and the direction of overlap changed, if necessary, to provide the trailing edge of each sheet on top of the leading edge of each succeeding sheet. The overlapped sheets are conveyed through an adhesive transfer station (7) where stripes (236) of at least partially dried adhesive are coated onto the dual coated sheets from a transfer belt (71).

Abstract: A pressure-sensitive adhesive comprising a blend of at least two components, wherein the first component is at least one pressure-sensitive adhesive and the second component is at least one thermoplastic material, wherein the components form a blended composition having more than one domain and, wherein one domain is substantially continuous (generally, the pressure-sensitive adhesive) and the other domain is substantially fibrillous to schistose (generally, the thermoplastic material). The second component can be (a) at least one thermoplastic elastomer, (b) at least one elastomer with a tackifying resin or (c) at least one elastomer.

Abstract: An adhesive tape is provided which comprises a woven cloth, a polymer embedded into the cloth so as to cause the warp and weft fibers of the cloth to bond together at their overlapping points but not to completely encase the fibers, and a pressure sensitive adhesive coated onto at least a portion of the polymer, wherein the adhesive tape is hand tearable in the down-web and in the cross-web direction. A method of manufacturing such a tape is also provided.
