Abstract:
A reinforcing sheet structure for reinforcing a box has a structural base sheet of high shear strength and an extended length and width dimension equal to major parts of at least two of the box length, width, and height dimensions, and a double-sided adhesive layer having an extended length dimension corresponding to a major part of one of the base sheet's length and width dimensions. In one embodiment, the reinforcing sheet structure includes a plywood sheet and an intermediate corrugated sheet bonded to the plywood sheet. The adhesive layer is a double-sided foam tape. In another embodiment, the sheet structure has at least one fold line for folding the sheet structure into two parts for reinforcing over a fold line between adjacent sides of a box. The reinforcing sheet structure may be used in multiple combinations both inside and outside the box.
Abstract:
A molded wood composite article man-made from wood fibers or wood particles on at least an upper, molded surface of the article, and a method of manufacturing the article to include a relatively uniform density, detailed design contours and textured aesthetics on one or more molded depression-interior inclined surfaces, while preventing embrittlement, softness and blistering of the article along the depression-interior inclined surfaces. These attributes are achieved by molding one or more depressions into an initially planar layer of cellulosic material, wherein the molded depressions have a length to depth ratio in the range of about 5.0 to about 8.5, and have one or more inclined walls that have upper surfaces, along essentially an entire inclined span, that include detailed design contours, including adjacent curved and planar portions, e.g., bead and cove. The inclined depression-interior molded walls, having upper surfaces that include the adjacent curved and planar contours, have a thickness or caliper measurement, measured normal to a tangent at any point along the upper (finished) contoured surface, that is smaller than the caliper so measured at horizontal, distal ends that are integral with the depression-interior contoured, inclined surface span, to make sure that the inclined surfaces of adjacent, stacked articles do not contact each other during shipping.
Abstract:
Optical diffusing structures can be fabricated from photopolymerizable material by directing light through a transparent or translucent substrate and then through the photopolymerizable material for a period of time sufficient to photopolymerize only a portion of the material. The resultant structure can be utilized as a diffuser, a viewing screen, and in other applications, and can be combined with other light-directing structures such as arrays of tapered optical waveguides.
Abstract:
A flexible multilayer metal structure includes using multiple layers interlocked to form folds holding the layers together. These folds can extend into non-edge portions of the multilayer structure so that the multilayer structure defines air gaps that aid in producing a heat-shielding effect.
Abstract:
A molded plastic panel for covering an exterior building wall includes a laterally directed lead fin, a laterally extending groove below the lead fin, and a rearwardly directed middle wall between rows of simulated shingles, all for joining laterally adjacent panels. A side flange extending outwardly of the panel may also be included. The molded plastic panel preferably also includes at least one row of simulated shingles separated by a plurality of gaps each having a randomly varying width in order to camouflage spacings between adjacent panels that change because of thermal contraction and expansion. In a particularly preferred embodiment, the panel body includes a locking tab and a folding flange. The folding flange includes a locking lip for engaging a locking tab on an adjacent panel and a flexible hinge connecting the locking lip to the panel body. The flexible hinge allows the folding flange to be disconnected from the locking tab when replacing a single panel.
Abstract:
A three-dimensional deep molded structure made from planar knits or wovens composed of homo-component, bicomponent or multi-component fibers having a fiber diameter of less than 100 microns and nonwovens composed of fibers or filaments of any size. Most suitably, nonwovens with a random fiber orientation distribution and a high degree of crimp with partially oriented fibers are preferred for use in forming the deep molded structure.
Abstract:
A wallcovering system, composite wallcovering and method for providing a smooth finished surface to wall substrate are provided. The wallcovering system comprises a composite wallcovering consisting essentially of a decorative wallcovering layer bonded to a base sheet having sufficient stiffness, thickness and compressibility to conceal surface irregularities on a wall surface of a wall substrate. In one aspect of the invention, the composite wallcovering comprises a layer of woven glass fiber adhesively bonded to a nonwoven fiber glass mat. The composite wallcovering can be installed in one step to provide a smooth finished wall surface on the wall substrate.
Abstract:
A paper machine clothing, especially a press felt (1), includes a support (2) which has at least one layer of a thread lap (3, 4, 5, 13) and which is embedded in a fiber matrix. Lap threads (6, 7, 8, 9, 10, 14, 17, 21, 25, 26, 27, 28, 33, 38, 43, 44, 45) run parallel to one another. The lap threads (10, 14, 17) are provided with outwardly projecting fibers (12, 16, 19).
Abstract:
A metallic porous body includes a number of protrusions formed on obverse and reverse sides of a metal sheet so as to protrude alternately with one another; each of the protrusions being formed into an truncated-shape wherein an opening portion punched out in the direction from the upper-side bottom to the lower-side bottom is formed in the upper-side bottom of each protrusion, and a vertical distance (d) between the upper-side bottom on the obverse side and the upper-side bottom on the reverse side, and a height (e) of a punched portion have a relation: 0.3
Abstract:
The acoustic characteristics of lightweight multilayer construction panels have been improved by the formation of three-dimensionally meandering curved slots or rows of slot sections in the core of the panels. The slot depth varies along the length of the curved slots. The slots or rows of slots are spaced from each other by an on-center spacing that is preferably constant along the length of the slots.
