  • Patent number: 4201819
    Abstract: A chipboard having bonded thereto a sheet metal lamination is disclosed. The sheet metal stretches and contracts in response to dimensional changes in the chipboard without becoming detached therefrom, thereby improving and preserving the strength and integrity of the chipboard. Also disclosed is a method of manufacturing thin laminated chipboard wherein a thermoplastic material, securely connected or bonded to a sheet of non-thermoplastic material, is laminated to the chipboard by contacting the thermoplastic film against the chipboard while applying heat and pressure against the non-thermoplastic material.

  • Patent number: 4145860
    Abstract: A tile, generally used for roofing purposes, made of metal or synthetic material, has two portions, one portion has a convex upper surface and another portion has a concave upper surface. These portions are integral with each other and do not overlap one another. The underfaces of these portions exhibit cavities thereat. The length of one of the portions is greater than the length of the other portion. When laid upon a roof area the ends of the tiles will be made to overlap a predetermined length of the tile to give the appearance of a roof formed with conventional spanish mission tiles. Adjacent or contiguous tiles are interlocked by means of a curled corner of the other portion of the tile.

  • Patent number: 4119750
    Abstract: A structural panel material of the sandwich-type construction includes inner and outer facings and a core bonded between the facings. The core includes a plurality of blocks of lightweight core material, such as rigid or semi-rigid plastic foam, balsa wood, or a combination of plastic foam. These blocks are arranged in strips. The strips are joined together by corrugated sheet material. In a preferred embodiment, double-sided corrugated paperboard is used to join the lightweight structural strips. The resulting core material has the highly desirable characteristics of being flexible enough to conform to a mold shape under gravity and with the application of little or no external pressure so that special jigs are not required.

  • Patent number: 4118261
    Abstract: A method of reinforcing fiberglass sheet material in which an inflatable envelope having a plurality of marginally sealed perforations therethrough is applied to the surface of the material. A wet layer of settable reinforcing material is then applied over the envelope and onto that part of the sheet material exposed by the perforations. The envelope is then inflated so as to cause the wet layer to assume a cratered form which is then allowed to solidify to form a reinforcing structure on the sheet material.

  • Patent number: 4112195
    Abstract: A composite molding structure combines a plurality of laminated body members with matingly engageable channels and extensions sized and shaped to at least partially interfittingly retain said body members from movement relative to one another, and filling and finishing members are so constructed and arranged as to conceal said channels and extensions whereby to impart a finished, contoured appearance and feel. The body members also include a variety of distinctive architectural configurations on their lateral sides which serve both as functional gripping surfaces as well as to impart an ornamental appearance to the finished molding. The various shapes and configurations with corresponding engagement means are conducive to the exercise of one's individual creativity in laminating various members together in a variety of combinations to produce finished moldings, handrails, balustrades and the like of desired size and appearance.

  • Patent number: 4103059
    Abstract: A light transmitting building panel comprising a flat central sheet and upper and lower corrugated sheets secured to the opposite faces of the flat central sheet, thereby to provide a set of upper cells and a set of lower cells. The upper corrugated sheet is laterally offset relative to the lower corrugated sheet whereby each upper cell is positioned intermediate of adjacent ones of the lower cells and whereby heat conduction between the internal and external surfaces of the panel is minimized. The flat central sheet and the upper and lower corrugated sheets are formed from a light transmitting glass fiber reinforced plastic. The present building panel is particularly useful in greenhouses as roof panels and wall panels. The long span capability, the light transmitting characteristic and the unique cell arrangement of the present building panel are advantageously employed in greenhouses.

  • Patent number: 4100312
    Abstract: An improvement is obtained in the bond strength between members of a laminate comprising a plastic substrate and a metal film through a process of first laminating to the plastic substrate a thin, sacrificial, anodized metal foil while providing at the interface prior to laminating of the foil to the plastic at least a mono molecular film of an organic silicon compound. After laminating the treated metal foil to the substrate under heat and pressure, the foil is chemically stripped from the substrate, leaving a surface of improved receptivity for conventional electroless plating and electroplating procedures, or other metallizing techniques. The final metal film when applied to the substrate exhibits consistently better adhesive strength than is obtained without the organic silicon treatment of the interface, especially in respect to adhesive strength at elevated temperature.

  • Patent number: 4096306
    Abstract: An improved strip material which may be inflated and sealed at the site of its intended use to form cushioning material. The strip material comprises two heat sealable films which are fused together in discrete areas to form two rows of inflatable chambers along the strip and a passageway extending the length of the strip material between the rows, with each of the chambers having an inlet opening narrower than the main portion of the chamber communicating with the passageway. The strip material is inflated by propelling the passageway in the strip over an air nozzle to inflate the chambers through their inlet openings, and the inlet openings are then sealed.

  • Patent number: 4087581
    Abstract: Microspheric opacifying agents are provided by admixing an aqueous, partially condensed, aldehyde condensation product with an oily material containing an emulsifying agent thereby forming a water-in-oil emulsion, admixing an amphiphilic acid catalyst with the emulsion and polymerizing the condensation product to form discrete, substantially spherical, opaque, solid particles. Additionally, the solid particles may be separated from the oily continuous phase and admixed with water for the further removal of oil material, and thereby causing the formation of spherical agglomerates or "super particles" having a substantially greater opacity than the aforesaid discrete particles. The super particles are hollow, substantially spherical particles having substantially spherical, discontinuous walls composed of agglomerated substantially spherical particles.

  • Patent number: 4076875
    Abstract: Ornamental element consisting of a number of tile-shaped parts which are joined, with interspaces, on the non-exposed side to form a bond. The adjacent tile-shaped parts are given a fixed relative bond by one or more joining strips, which form one whole with the tile-shaped parts, and consist preferably of one and the same material, and are moulded in one action.The joining strips are made as bridgings, the height of the opening of which plus the tile thickness is equal to or larger than the width of the joint between the tile shaped parts; the thickness if equal to or smaller than the width of the joint. The bridge-shaped parts have a form which allows release from a mould.The ornamental element consists of a thermosetting agent, for example of an unsaturated polyester with fillers or a ceramic material.
