Abstract: A multiplanar device has at least one component that consists of two rigid plastic wall members that have major areas of substantially uniform thickness, strips of considerably greater thickness along the side portions of said wall members, and a miter joint between the two wall members. A continuous thin film of flexible plastic is bonded to the two wall members and around the outside of the miter joint.The method of making the component is to mold it as a flat intermediate piece with a V-notch between the strips of greater thickness and to simultaneously bond the film to the surface at the apex of the V; and to thereafter apply adhesive to the sides of the V and bend the piece to bring the sides of the notch together and bond them together.Several such components may be connected with other similar or dissimilar components at miter joints to form a complete multiplanar device.

Abstract: An opaque recording material has an opaque sensitive layer which can be transparentized by application of heat or a suitable solvent for the opacifying styrene resin pigment which is dispersed in a polyvinylidene chloride film-forming resin binder. In a particular application, useful for overhead transparencies or for making photographic negatives for reproduction, heat and solvent are both applied to the opaque layer in selected different areas to transparentize the opaque layer. The opaque layer may be deposited on a transparent clear or colored support such as transparent polyester.

Abstract: A continuous layer of transparent material is formed on a base. A desired pattern of transparent electrically conductive material is included in the layer. The regions of the layer not included in the conductor pattern are insulative. The insulative material is preferably an indium oxide. Tin is preferably used as a dopant in the indium oxide to made it electrically conductive according to the desired pattern. The electrically conductive pattern is first formed in metallic tin. The tin pattern is diffused into a layer of metallic indium. The layer is then thermally oxidized to form the electrically conductive pattern as indium-tin-oxide (ITO) in indium sesquioxide, In.sub.2 O.sub.3, an insulator.

Abstract: Method of constructing a large poster for a back-lighted signboard from a plurality of smaller poster sections including improving the translucent quality of the poster material, aligning respective adjacent sections for exact image continuity, laminating a clear film over a first poster layer, laminating a second poster layer over the clear film, and applying heat and pressure to create a composite laminated poster having registered images throughout.

Abstract: A natural stone panel is constructed from rectangular sheets, slabs or blocks of natural stone, particularly marble or onyx and constructed by placing an array of rectangular stone blocks on a work surface, placing a fiberglass backing on the upper surface of the array, applying an adhesive, which can have a stone dust filler, to the joints between adjacent blocks, on the blocks and on the fiberglass backing, which is rolled into contact with the blocks. After hardening or curing of the adhesive, the exposed stone block surfaces can be polished, an overlay of clear plastic applied to the surface of the stone blocks, and the panel edges trimmed with a suitable cutting tool. The panels formed can be wall mounted by a suitable adhesive bonding the fiberglass backing to the wall surface, or alternatively, the panels can be adhesive bonded to a floor surface.

Abstract: A decorative mirrored tile or the like preferably comprises a square transparent plate of glass or the like of substantially the same thickness throughout including the marginal portions thereof, and a mirror-forming surface at the rear of the plate extending to the margins thereof. There is provided along a band at each margin of the plate innumerable, tiny, spaced light interrupting areas or spots contrasting to the light transmitting characteristics of the tile between the same and the density of which varies progressively in a direction generally parallel to the plate margin involved, reaching maximum and minimum densities respectively at opposite ends thereof where they terminate along respective lines substantially bisecting the angle between the plate edges intersecting the corners of the plate thereat.

Abstract: A seamless pattern tile made by bonding a paper, plastic or like pattern, preferably with chips sprinkled thereon in an adhering manner, to a floor or like substrate, which may be of a contrasting color.

Abstract: Improved placement apparatus comprises a compliant backer sheet, e.g., formed of foamed polyvinyl chloride, and a clear transparent overlay sheet, e.g., of vinyl, disposed over the backer and secured on three sides thereto, as by thermowelding, to fuse the contiguous backer and overlay plastic materials.A graphics sheet desired by a consumer, e.g., a wallpaper or fabric segment, is inserted between the backer and overlay, and enclosed by securing a flap-like member affixed to the overlay to the backer sheet. A double sided acrylic copolymer adhesive strip is advantageously utilized to secure the flap and backer sheet.

Abstract: Photopolymeric image inlay articles comprising a photopolymeric image inlaid into a resilient polyester resin coated matrix of a solidified synthetic rock-like mixture.

Abstract: Water-color pictures having neat border edges rendering them suitable for framing are made by cutting a rectangular opening of a desired size through a ruled transparent plastic top sheet adhesively secured in removable fashion to a back sheet of water-color paper and removing the cut portion of the plastic sheet to provide a sight area within which a picture or the like may be colored. The remaining portion of the plastic sheet-framing the sight area prevents the watercolors from extending beyond the sight area, and upon completion of the coloring, the remaining portion of the plastic sheet is stripped from the back sheet, whereupon the back or mat sheet is then ready for framing and/or display.

Abstract: A decorative object comprising an acrylic glass support plate and differently colored polymethyl methacrylate layers and zones thereupon, on one or both major surfaces of the plate, differently colored zones and vertically superposed layers of polymethyl methacrylate being separated from each other and from the support plate by barrier elements and layers respectively which are optically and mechanically compatible with but completely insoluble in and unpenetrable by polymethyl methacrylate.

Abstract: instead of following the conventional practice of removing the previous floor covering of sheet linoleum, floor tiles or the like, the floor tiles of the present invention are so remarkably thin that they are laid on top of the old flooring while still providing adequate clearance for doors, drawers, and related items imposing limits on the floor elevation. The principal layer has a thickness of organic composition from 0.005 inch (5 mils) to 0.040 inch (40 mils) and the cured transparent polyurethane top layer is at least 0.001 inch (1 mil) and not more than 10 mils in thickness. The combination of principal layer and top layer has a thickness from 0.010 to 0.045 inch. By keeping the flooring so thin, its usefulness for installation over existing flooring without exceeding the available clearance is enhanced.
