  • Patent number: 6933037
    Abstract: A three-layer asphalt composition shingle where the top layer is of a full width, a middle layer is less than the full width, and a bottom layer has a width shorter than the middle layer. The middle and top layers of the shingle have tabs and cutouts. The tabs of each such layer generally differ in some feature. Moreover, the corresponding tabs between the middle layer and top layer also differ with respect to some feature, such as a lengthwise size, a widthwise size, shape or in color. Each of the three layers includes color zones, and often plural color zones. The different tab features and the different color features of the various layers provide a high degree of randomness to enhance a visual appearance to a roof shingled with such type of shingles.

  • Patent number: 5567535
    Abstract: Currently, fiber/metal laminate sheets are limited in width due to restrictions in the width of thin metal sheets available. This invention solves that problem by providing an integral splice concept and a method for manufacturing a laminate employing the inventive concept. Specifically, a fiber/metal laminate sheet is provided having at least two metal plies and at least one fiber layer. Each of the metal plies comprises at least two metal sheets which are arranged side-by-side and have sheet metal breaks therebetween. All of the sheet metal breaks lie within the integral splice. An important feature of the invention is that the sheet metal breaks in each metal ply are staggered widthwise across the laminate with respect to the sheet metal breaks in the remaining metal plies, in accordance with a predetermined metal break staggering pattern, thereby maximizing the bond engagement of the discontinuous metal plies with the adjacent fiber layers.

  • Patent number: 5468533
    Abstract: A masking material includes a stiffened edge for easier insertion of the edge between closely abutting panels or surfaces as might be encountered in preparing a motor vehicle for painting or other such surface treatment. Preferably, a thin, flexible base layer includes an edge piece characterized in that it is flexible but more rigid than the base layer itself, enabling the edge piece to be inserted between closely spaced articles, with the remaining base layer being folded over the article to be masked, thereby providing an abrupt masking interface. One such article might, for instance, include a flush-type rubber molding incorporated into modern motor vehicles. In the preferred construction, the base layer comprises a tape with an adhesive surface, the edge piece being a flexible plastic strip which is narrower than the width of the base layer and adhered to the base layer using the adhesive surface.

  • Patent number: 5262217
    Abstract: A sandwich panel element comprises a core of fibrous material arranged between first and second parallel outer skins of generally planar sheet material. The core material consists of a plurality of elongate strips arranged in side-by-side and end-to-end abutting relationship. The strips are formed so that the fibers are in a direction generally transverse to the planes of the sheet material. The strips are individually shorter than the length or width of the panel element and the mutually abutting ends of the strips are staggered with respect to rows of adjacent strips. The ends also may be chamfered at an acute angle to the longitudinal direction of the strips to allow the ends to overlap.

  • Patent number: 5208080
    Abstract: A method is disclosed for producing superior optically clear laminates having a sheet of semi-rigid material encapsulated in a thermoplastic interlayer between layers of rigid material such as glass. Pre-cooled laminate elements are assembled at reduced temperature, allowing positioning of the sheet of semi-rigid material in the interlayer of the assembly with minimal wrinkling, formation of air bubbles or entrapment of moisture. Thereafter, the laminate assembly is maintained under vacuum for an extended period of time, substantially eliminating wrinkling, air bubbles and moisture from between the laminate elements as well as pre-forming the semi-rigid sheet. Bonding heat and pressure is then applied, first heating the assembly to "tack" the laminate elements together, and next applying heat and pressure for bonding the laminate elements.

  • Patent number: 5196255
    Abstract: An extruded slat defined by a series of longitudinal cavities disposed in a side-by-side relationship. Typically, the longitudinal cavities total in odd numbers so that fastening can be achieved through a single cavity. The slat is fabricated from plastic resin, is light in weight, is readily cut and can be arranged into a variety of configurations. Assembly between the ends of abutting slats is usually accomplished by an interconnecting pin(s) between communicating cavities. Each longitudinal cavity is also adapted to receive a rod, a cable, or the like, serving for example, reinforcing, communication and/or communication purposes, or other uses involving concealment and/or security.
