Abstract: A decorative surface arrangement for an article of furniture includes a plurality of tiles, at least some of which carry decorative matter on their exposed surfaces. The edges of each tile have retaining means cooperable with retaining means on the edges of other tiles to maintain the tiles in engagement with one another while permitting relative sliding movement between the tiles in the plane of the decorative surface. The tiles move within a frame fixed to the furniture and engage retaining means carried by the frame. There is space available within the frame for accommodating one tile more than the number of tiles within the frame. The retaining means may include tongue means projecting laterally from part of the circumference of each tile and groove means in the remaining part of the tile circumference.

Abstract: A light-weight, high-strength contourable core for inclusion in a contoured structural laminate in which the core is sandwiched between facing skins. The core is constituted by a planar array of block-like modules preferably made of end-grain balsa wood held together in edge-to-edge relation by a scrim formed by elastomeric filaments which extend through the body of the modules in an intermediate plane parallel to the opposing faces of the core. When the planar core is pressed against a wet-coated contoured skin surface for lamination thereto, the filaments bridging adjacent modules elongate to an extent permitting these modules to separate and conform to this surface. The filaments have an elastic recovery force low enough to prevent the modules from overcoming the surface tension created by the wet-coated surface and pulling away therefrom. However, the holding power of the filaments is sufficient to preclude disassembly of the core modules during normal core handling procedures.

Abstract: A wear surface such as steel bridge deck surfaced with a wear-resistant overlay such as plastic tiles is disclosed in which the tiles are bonded to the deck by means of a bonding layer having preferably a shore 00 hardness of from approximately 78 to 90 and comprising an elastomer compounded with a stiffening filler in an amount equal to at least about half the weight of the elastomer. Low volatile liquid plasticizer is present in an amount to provide the stated hardness. The elastomer is preferably a mixture of acrylic elastomer and butyl elastomers, and the stiffening filler is a high abrasion furnace carbon black. The tiles are adhered to the layer with a solution coating comprising neoprene in admixture with a terpene-phenolic resin and the coating desirably includes a hydrophobic silica.

Abstract: This disclosure relates to a new adhesive device and method of forming the same which includes providing a laminate comprised of a felt substrate, release paper, and adhesive. The release paper is permanently attached to one side of the felt substrate to form a sheet having a felt side exposed and a release side of the release paper exposed. This sheet may be divided into sections (to form a plurality of separable pads or sections) by a cut extending through all but connecting tabs between adjacent sections on the sheet. Adhesive is applied to all but a peripheral edge portion of the other side of the felt substrate on each of the sections. A plurality of sheets or laminates may be stacked with the adhesive on one laminate adjacent the exposed release side of the release paper on another laminate. In addition, a separate sheet of release paper may be placed adjacent the exposed adhesive on the outermost stacked laminate.

Abstract: The magnetic anisotropy field in a layer of magnetic material on a substrate is determined by a method involving the application of a magnetic field upon whose release a so-called "sea of bubbles" is observed. The direction of this field typically is at a nonzero angle of elevation relative to the layer.In accordance with the invention, a preferred angle of elevation is determined upon inspection of a functional relationship between angle of elevation and magnetic field strength associated with the observation of a sea of bubbles. Results obtained by the method compared favorably with results obtained based on magnetic resonance techniques and, since the method is also relatively simple, it is particularly suitable for quality control in the manufacture of magnetic bubble devices.

This difference in structural characteristic serves to provide an inherent arrestment barrier against fast rupture propagation of fractures which may develop in the basal tract material when the composite strip is subjected to sustained overload or external damage.
