    摘要： Smooth surfaced panels e.g. of oriented strand board are prepared by producing a thin uniform mat of high density made from bonded wood particles, fibers or strands. The mat is produced by passing it between a pair of rollers one of which is heated to produce a smooth cured surface on the corresponding side of the mat, and the other of which is unheated, the corresponding side of the mat containing uncured adhesive. The mat is subsequently bonded to a panel, e.g. an oriented strand board core under conditions of heat and pressure to produce a composite panel having a smooth surface.

    摘要： The invention relates to a ligno-cellulosic building board having a nonrepetitive textured surface on at least one side. This side consists of a layer of ligno-cellulosic particles with elevations and depressions, the specific gravity of the particles of the elevations being substantially the same as the specific gravity of the particles in the depressions. The density of the fibers at the surface has therefore been equalized over the entire area of the board. In one form of the invention a layer of coarse particles is used, the sharpness of the edges of the coarse particles being concealed with fine particles. The product is produced by pressing a layer of binder coated ligno-cellulosic particles on a substrate in a hot plate press with a cushion, preferably of silicone rubber, between the hot platen of the press and the layer of particles.

    摘要： A container for cosmetic products and a method of manufacturing the same. The container, such as a jar, has a wall formed by a first layer of a compostable material which comprises in combination a biodegradable polymer which forms a continuous matrix and, mixed therein, particles of a hydrophilic material capable of swelling inside the matrix upon water absorption. The container further comprises a second layer of a compostable material which comprises a biodegradable polymer which forms a continuous matrix and which is essentially free from particles of a hydrophilic material capable of swelling inside the matrix, or contains essentially less of them than the first layer. The container is degradable in compost, disintegration of the container wall, at 58° C., occurring within 12 weeks.
