Abstract: Engineered structural wood products particularly useful in critical applications such as joists, headers, and beams where longer lengths, greater widths, and higher and predictable stress ratings may be required and to a method for making the wood products. Most logs by nature are radially anisotropic, having wood of higher density and stiffness in their outer portion adjacent the bark than is found in the inner portion. The logs are machined to segregate the denser, stiffer outer wood. A first generally rectangular component is formed from the less dense inner wood. Second generally rectangular components are formed from the stiffer outer wood. Second components are adhesively bonded to at least one edge of the first component, more usually to opposite edges. The stiffer wood is thus specifically placed where it will contribute most effectively to the properties of the product.

Abstract: A method of making dual or multi-porosity porous plastic strips comprising placing a first quantity of plastic granules into a mold, and placing a second or additional quantities of plastic granules into the mold above the first quantity. The particle sizes of each of the quantities of granules placed into the mold are different from the particle sizes of all the other quantities of granules in the mold. The granules are subjected to heat and pressure so as to fuse them together into a self-sustaining porous plastic billet. The billet has a number of fused-together regions corresponding to the number of quantities of granules placed into the mold. The billet is sliced in a direction transverse to the planes containing the interfaces between the regions of the billet so as to create strips, each strip comprising interconnected regions have porosities which differ from one another. The mold may be cylindrical and the strip created by skiving it off the cylindrical surface of the billet.

Abstract: The present invention provides a method of manufacturing high quality laminated veneer lumber from pre-flattened wood veneer, for such uses as in architecture and furniture, and a method of mass production thereof using veneer which is flattened in advance. A sheet of veneer is first obtained by cutting a log with a rotary lathe or the like, and flattening and cutting the veneer into a predetermined length. Sheets of veneer thus obtained are cut on both edges in the grain direction to form symmetrically diagonal end faces, and are bonded with one another at these end faces with their grain directions aligned to form an elongated sheet of veneer. The resultant elongated sheet veneer is cut into a predetermined length to form laminated veneer material having seams. Plural sheets thus formed laminated veneer material are laminated and bonded with their grain directions aligned to form laminated veneer core.

Abstract: A hose manufacturing process and a method therefor capable of leading to an increase in production efficiency and productivity and improving configurational and dimensional stability of the hose. A die is provided for co-extruding a flexible synthetic resin material and a rigid synthetic resin material to concurrently form an inner tube of a small diameter and a reinforcement which is concentric with the inner tube and has a diameter larger than the inner tube, respectively. Also, a cutter is arranged forward of the die in a direction of extrusion of the reinforcement for cutting the reinforcement into a spiral shape. Further, a compression air feed passage is formed in the die so as to feed compressed air into the inner tube, to thereby expand it. This permits the inner tube to be contacted with the reinforcement for adhesion therebetween.

Abstract: An image producing and transfer apparatus which utilizes a base sheet covered with a tacky adhesive which in turn is covered with a liner sheet composed of a plurality of individually removeable liner segments. Part of the apparatus includes a plurality of break-away members which are manufactured at the same time as the apparatus and of the same material of construction and the same die cutting process to become a tool in the method of this invention. Each break-away member includes a tacky adhesive surface which, when applied to the outer surface of one of the liner segments, facilitates the removal of that liner segment thereby exposing an area of the tacky adhesive which can now be covered with a particulate matter. All liner segments are removed in this manner. When all liner segments have been removed and the particulate matter applied, there remains a border segment. A liquid glue is coated onto the completed image of this particulate matter with some of this glue coating the border segment.

Abstract: A method of manufacturing a molding material includes the steps of winding a thin metal strip on the peripheral surface of a rotary shaft a plurality of turns with a resin material being interposed between the resulting layers of metal, cutting an end surface of the metal strip and the resin material which have been wound by a cutting blade while rotating said rotary shaft to obtain a mixture of metal fibers and resin fibers, and heating the fiber mixture to a temperature at which the resin fibers can be softened. In this way, a molding material in which the metal fibers are substantially uniformly dispersed in the resin material in a closely contacted state can be obtained easily. Furthermore, the contents of the metal fibers by volume in the molding material can be arbitrarily adjusted by changing the rate at which the metal strip and the resin material are wound around the rotary shaft.

Abstract: A method of producing laminated veneer lumber (LVL) with good dimensional stability, characterized by a particular lay-up of the veneers and the veneers being of at least two different wood species. The particular veneer lay-up and species arrangement, minimizes the tendency of warping and cracking of the LVL. All veneers are laid-up in pairs by species with the loose sides of each pair contacting each other and with the species pair sequence from face to core being identical on either side of the center ply or center line. The veneer tight faces of different species are bonded to one another. The dimensional stability of the LVL is optionally enhanced by a water repellent, flow promoter and bulking agent that is incorporated into the adhesive before application onto the veneer. The different species veneers are dried to different moisture contents before lay-up with the denser species being of lower moisture content than the less dense species.

Abstract: A method and apparatus for making a composite component. For making a non-cylindrical composite component such as a nozzle, a longitudinal winding of at least one fiber strand impregnated with resin is applied onto a generally cylindrical mandrel at a predetermined angle relative to a line parallel to the mandrel rotational axis. A transverse tape is then spirally cut from the layer and wound onto a component mandrel. The wound transverse tape is then compacted and cured and the mandrel removed. A nozzle exit cone is also disclosed made from such transverse tape so that the fiber strand portions are short enough that they do not follow the curvature of the nozzle and thereby peel. The windings are shingled onto the nozzle exit cone so that only one end of each of the fiber strand portions is exposed to the nozzle surface. The fiber strand portions are oriented at a predetermined angle which may be optimized for erosion resistance and stress requirements.

Abstract: This application relates to composite structures and, more particularly, to a composite or sandwich structure employing sheets of wood veneer.

Abstract: A wooden tile which is preferably used for floor covering is formed by a number of individual members which are bonded together. The wooden tile is made by knife cutting a sheet of wood from a substantially stressless piece of timber and then cutting the individual members from the wooden sheet. Adhesive such as ureaformaldehyde is applied to the edges of the members to bond them together. Alternatively, the individual members are adhesively bonded onto a mesh and some adhesive seeps between the edges of the members. The tile so formed is flexible, durable and economic to manufacture.

Abstract: The present invention relates to a novel foam peeling process and apparatus. The process and apparatus allow for the substantially continuous production of a continuous sheet of foam material in roll form from a cylindrical foam body. By following the present invention, several basic operations may be performed on a foam body including inserting a supporting rod in the foam body, bringing a cutting element into contact with the foam body while it is rotating on the supporting rod, winding the resultant continuous foam sheet and returning the supporting rod back to the inserting station. The invention allows for the production of a foam roll in a substantially continuous manner with a minimum amount of labor. Furthermore, all the various operations can be controlled via suitable electrical control means, and it is preferable that all the various operations be programmed into a single control unit.

Abstract: A high yield technique to convert normally-unusable round logs of balsa or other species of wood whose diameter is less than about 4 inches into large rectangular panels that are contourable.The raw logs are first peeled to expose the wood and are then cut into round pieces of a desired length. The pieces, after being kiln-dried, are stacked to form a dry assembly in which the pieces are separated from each other to define a matrix of intersticial spaces. The pieces in the assembly are then interlaminated in a mold by filling the matrix with an elastomeric plastic solution which, when cured, functions as an adhesive to provide an integrated stock block. The stock block is then divided into panels of the desired thickness, each panel being constituted by an array of round wood tiles joined together by elastomeric hinges, whereby the resultant panel is contourable and may be conformed to a curved surface.

Abstract: A high-yield, low-cost technique for converting balsa wood logs into thin, flat sheets usable in model-making. In this technique, the log is first debarked and then cut to a standard bolt length. The bolt is supported for rotation in a veneer lathe which acts to peel off in spiral form a continuous web of balsa veneer. After kiln drying, dried sheets taken from this web are clipped to a usable width, the sheets at this point having a curvature as a result of their spiral memory. Then the sheets are assembled into matching pairs of opposing curvatures, each pair of sheets being laminated together in face-to-face relation to produce a two-ply flat sheet whose planarity, upon exposure, is immune to changes in relative humidity and temperature.

Abstract: Veneer production from softwood logs is improved by adding at least about 0.003% of urea to the hot water soaking vats prior to peeling the veneer from the logs. Enhanced results are achieved when urea is added together with a base such as sodium hydroxide.

Abstract: A method of making coherent optical fiber bundles and coherent optical fiber face plates. The method includes the steps of forming a laminated billet by heat and pressure from a plurality of stacked disc modules. Each disc module is defined by two transparent discs, one relatively thick and having one index of refraction and the other relatively thin and having an index of refraction less than the first. The billet is then longitudinally skived to form a veneer strip of indefinite length. The veneer is then coated on one or both faces by transparent sheets having similar optical properties, i.e., different indices of refraction, and may include a light-absorbing or light reflecting layer on one sheet. A second billet is formed and transversely cut to define a fiber optic face plate. A second billet may also be formed and skived to yield a coherent fiber optic bundle.
