Abstract: A building component in the form of a board-like distance plate having a lattice of horizontal and vertical ribs. Frusto-pyramid projections (3) extend from the intersections of the ribs on one side of the board and domes (4) extend from the other side of the board between the ribs and cover a larger surface area than the projections (3). The domes form cavities which are interconnected by virtue of the projections spacing the plate from a wall or other surface.

Abstract: A floor mat is provided with a generally flat upper wall with a multitude of y-shaped ribs extending vertically downward from the upper wall to a floor surface, supporting the mat. Each of the y-shaped ribs has a solid central core with three legs which extend horizontally radially outward from the core. The distal end of each of the legs is bulbously enlarged. The ribs are spaced apart in a symmetrical pattern so that two sides of three adjacent ribs cooperatively define a generally cylindrical pocket. The pocket, while forming an enclosure, nevertheless had lateral openings at three equally spaced locations formed by the ends of each of two adjacent ribs being spaced slightly apart allowing for ingress and egress of air from the pocket. Located above the center of each pocket is a hollow dome formed in the upper wall.

More specifically, the releasable seal of the present invention is directed to the simultaneous embossing of precisely configured indentations, involving multilayer films which can heat seal together during the embossing operation; the resulting seal layer is designed and configured to delaminate and tear when the package is initially opened, while the indentations are designed and configured to re-engage and partially re-seal when the package is later closed.

Abstract: This invention relates to the discovery that the perceived softness of embossed tissue can be increased greatly while avoiding prior art nesting problems if a particular pattern is embossed into the tissue. This pattern combines relatively shallow stitchlike debossments with deeper more sharply defined signature debossments. The stitchlike debossments are rounded and arranged in wavy flowing intersecting lines. The signature debossments are arranged in regions framed by the intersecting wavy flowing lines.

Abstract: A uniformly flexible core, and method for manufacturing the same, for use between the face plates of a sandwich structure. The core is made of a plurality of thin corrugated strips, the corrugations being defined by a plurality of peaks and valleys connected to one another by a plurality of diagonal risers. The corrugated strips are orthogonally criss-crossed to form the core. The core is particualrly suitable for use with high accuracy spherically curved sandwich structures because undesirable stresses in the curved face plates are minimized due to the uniform flexibility characteristics of the core in both the X and Y directions. The core is self-venting because of the open geometry of the corrugations. The core can be made from any suitable composite, metal, or polymer. Thermal expansion problems in sandwich structures may be minimized by making the core from the same composite materials that are selected in the manufacture of the curved face plates because of their low coefficients of thermal expansion.

Abstract: In one embodiment, the pack is torsionally flexible. Pack of laminations comprises laminations which are connected one to another by only a single connection. The single connection is provided by a projection which projects into a depression. The projection has a height which is greater than 50% of the thickness of the lamination and the depression has a depth which is greater than 50% of the thickness of the lamination. The depression and projection are produced by a projection punch which cooperates with a die. The die has a lip which is either radiused (r) or conical (C) and the punch causes the metal of the lamination to be extruded past the lip into the die while the depression is being formed. The radiused or conical lip allows the height of the projection and the depth of the depression to be greater than the normal 50% shear stress fracture depth/height.

A method of forming the stiffeners in glass fibre/resin composite is also disclosed.

Abstract: With the composite plates for raised floors which are supported at their four corners and consist of a shell with open top and manufactured of tension-resistant material as well as a filling of pressure-resistant material, for instance anhydrite, when the plate is under stress there is a higher deflection at the plate border than in the middle of the plate, which is undesirable. In order to substantially equalize the bearing strength of composite plates of the above structural design in the border and the middle of the plate and to assure such plates against rupture at the border, a reinforcement which is practically plate-high is provided on the side wall of the shell, which is connected with the bottom plate of the shell. In addition or alternatively thereto the density and strength of the filling in the border area of the composite plate could also be increased at least twofold as compared with the rest of the area extending toward the middle of the plate.

Adjacent strips are mirror images of each other and connected along adjoining sides with the angles of the four corners of adjacent segments being alternately less than 360.degree. and greater than 360.degree. along the length of a strip such that the sheet material has an undulating configuration, and is inherently curved and cannot lie in a flat plane.

Abstract: A cushioning material for mattresses is formed by needling a pile of crimped fibers to form a flat board, and then continuously and alternately bending the flat board to form a corrugated web. The corrugated web thus formed has a number of side-by-side contact portions and a number of bent portions connecting the side-by-side contact portions. The bent portions thus form a relatively soft surface portion of the cushioning material, and the side-by-side contact portions provide a moderately rigid portion of the cushioning material. The corrugated web may be held together by sewing, bonding or welding.

Abstract: A disposable foil grill is disclosed which consists of a corrugated and perforated sheet of heavy duty aluminum foil. The corrugations allow smoke to access virtually the entire bottom surface of the food being cooked so that the desired barbecue flavor is obtained. Fat from meat being cooked drips into troughs formed by the corrugation and exits through holes in the troughs onto the coals for generation of the smoke and flame which give food a desireable barbecue flavor. Another advantage of the disclosed disposable grill cover is that the distances between adjacent troughs may be changed by a slight pull on the ends of the foils to perfectly align the troughs with the spacings between the wire grating of the grill. In this way, holes formed in the bottom of the troughs for fat drippings do not allow the drippings to come in contact with the wire grating.

The metallic thin sheet skin pass rolled by this roll is used as a car panel and is superior in pressworkability and sharpness of reflections.
