Patent number: 5747140Abstract: A completely vented upholstered body of grid plates with a wave profile includes solid portions of the grid which pass through the wave extrema of its wave contour. Many of the solid portions of the grid preferably are disposed transversely to at least one wave propagation direction and, in each case, continuously over a large portion of a wavelength, at a distance from one another. There is only a limited, specified bending deformation, during which the solid portions of the grid can be deformed largely independently of one another as if they were individual spiral springs. As a result, the upholstered body has a high point elasticity despite the plate construction. By adroit dimensioning of the course of the wave thickness, an advantageous diffusion of stresses can be achieved without stress peaks. Moreover, the work of deformation is absorbed uniformly in the upholstered material. This results in a long service life of the upholstered body.Type: GrantFiled: March 22, 1996Date of Patent: May 5, 1998Inventor: Siegfried Heerklotz

Patent number: 5597629Abstract: To produce a pultrusion which can be machined without undue strength loss bidirectional woven fiber fabric is modified to be pultrudable into a high shear strength composite member. In a preferred form of the invention the fabric is pleated in the pultrusion process to create an endless wall of stacked switchback pleated layers which defines a box beam wall in one example, and the shaft of a bolt in another. Products produced by this process have improved isotonic strength qualities over currently produced pultrusions, which are limited to unidirectional fibers, continuous fiber mats, or alternating layers of non-woven 0.degree. and 90.degree. cloth and do not have the shear strength inherent in the pleated configuration.Type: GrantFiled: January 26, 1995Date of Patent: January 28, 1997Assignee: Ebert Composites CorporationInventor: David W.

Patent number: 5597639Abstract: The perceived softness of embossed tissue can be increased greatly while avoiding nesting when a particular pattern is embossed into the tissue. This pattern combines relatively shallow stitchlike bosses with deeper more sharply defined signature bosses. The stitchlike bosses can be rounded and arranged in wavy flowing intersecting lines. The signature bosses can be arranged in regions framed by the intersecting wavy flowing lines.Type: GrantFiled: December 20, 1993Date of Patent: January 28, 1997Assignee: James River Corporation of VirginiaInventor: Galyn A.

Patent number: 5595811Abstract: A free-flowing dunnage packaging material formed from individual dunnage elements which are individually constructed from small sheets of paper, such as small paper squares, with the sheets being preformed into cup-like configurations so that such material, when used to fill a space or region between an article and a surrounding confinement, possesses sufficient strength to permit safe but cushioned support of the article.Type: GrantFiled: September 1, 1994Date of Patent: January 21, 1997Inventor: William A. Stout, Jr.
