Abstract: A method for wet gluing of wood fibers, which have been defibrated in a refiner from wood comminuted into chips, in order that these chips, following wet gluing in a gluing zone, can be dried in a dryer, then spread, in a spreading arrangement, to form a fiber mat and pressed, in a hot press, to form a wood-material panel. The wood fibers are transported into the gluing zone, within a conveying tube, in a stream of saturated steam. In order to calm the fiber stream, the conveying tube widens at the start of the gluing zone, within which a plurality of gluing nozzles are situated, as a result of which the speed of the fiber stream is reduced before the first gluing nozzle has been reached, the fibers in the calmed fiber stream are glued with adhesive by the gluing nozzles, and then are fed to the dryer.

Abstract: The wet friction material of the present invention is obtained by impregnating a friction base material with a bonding resin composition comprising a resol phenolic resin and a maleinized drying oil and curing the resulting material. The maleinized drying oil is obtained by reacting a drying oil such as tung oil or linseed oil with anhydrous maleic acid. The content thereof is preferably 50 to 250 parts by weight, based on 100 parts by weight of the resol phenolic resin. The wet friction material of the present invention has a high static friction coefficient and excellent durability.

Abstract: The high refractive dielectric film which can be used stably as a constituent material of an optical multi-layer film, namely, and which does not cause change over time in optical properties and has small film stress, is an amorphous material having no columnar structure, obtained by adding to a main component titanium oxide (TiOx: 1?x?2) another metal oxide (MOw: M represents a metal such as niobium, tantalum, 1?w). Though titanium oxide is a material which tends to manifest a crystalline structure even in the form of a thin film, a mixed high refractive dielectric film can be obtained, containing titanium oxide causing little change over time in optical properties by rendering the resulting thin film amorphous by inhibiting growth of a crystal of titanium oxide by adding another metal oxide.

Abstract: Biodegradable, agricultural mulches are prepared by coating paper with a cross-linked drying oil or a cross-linked, functionally modified drying oil. These mulches are inexpensive to produce, and are also water-resistant, mechanically stable and highly effective as weed barriers. The reactivities of various drying oils permit the development of a broad spectrum of coating systems and coating properties. In one embodiment of the invention, it is contemplated to complete cross-linking of coated paper in the field through either oxidative or photoinitiated processes.

Abstract: A canvas for use by an artist for painting includes a flexible substrate material having a surface coating of a refined animal glue which forms a translucent glaze as the painting surface. The substrate is preferably open-weave nylon having a denier value of between 200 and 400 denier, inclusive. A binding intermediate coating of either rabbit skin glue or a whitener may be used to increase the binding of the surface coating to the substrate, and the coated substrate may be mounted on a stretching framework and, if desired, backed by butcher's paper. The production process for this canvas includes the steps of coating a sheet of the substrate with a binding material, drying this first coat, glazing the material with a glazing compound that dries to a translucent layer, and drying the glazed sheet. This process may be a continuous stream production process.

Abstract: Printed materials such as tickets, lottery forms, cards and contest forms, bearing a hidden message which is revealable by scratching off a covering opaque layer, are prepared by printing the message on the substrate, lithographing a protective layer such as a clear varnish or a pigmented varnish-ink over the hidden message, and then lithographing a hiding coat over the applied protective layer. The protective layer formulation and the hiding coat layer are both based upon compatible, preferably the same, film forming resin systems, and are deposited from a common solvent. The protective layer may provide a clear, colorless transparent film through which the message may be viewed, or a colored see-through layer, so that it constitutes one color layer also for the printing of other areas of the substrate.
