Abstract:
Anti-reflective composites (84) comprising carbon-based polymer substrates (86),such as polyesters, are antireflected by applying to the substrates one or more discontinuous layers of inorganic materials (88, 92) having an index of refraction greater than that of the substrates.
Abstract:
Des films plastiques réfléchissants métallisés utilisés dans des réflecteurs d'appareil d'éclairage ont un rendement amélioré lorsque le film plastique sur lequel est déposée la couche de métallisation contient un absorbeur d'ultraviolets.
Abstract:
Curved, insulating glazing structures (14) and their preparation are disclosed. The glazing structures (14) comprise two rigid outer surfaces (21, 22) (generally glass), and a suspended inner film (23) surface parallel to the outer surfaces (21, 22). The inner film (23) is adhered to the outer surfaces (21, 22) only on its curved edges - its straight edges (16, 16a) being unattached. The inner film (23) is generally heat shrunk in the direction parallel to the straight edges and preferably carries a heat reflective coating.
Abstract:
Metallized plastic sheet film products improved by being perforated through their surfaces are disclosed. These sheet products can be incorporated into improved strength composites since their perforations permit glue through and prevent delamination and shear previously observed with metallized plastic sheet film products. In addition, the perforations can be used to adjust the conductivity/resistance of the electrically conductive sheet films.
Abstract:
A multiple pane glass unit having a pair of spaced glass panes on opposite sides of a pair of spaced, generally parallel, electrically conductive, transparent films mounted by spacers in a taut condition in the space between the panes. The films are in electrical contact with one or more electrical conductors, such as wire cloth, and the electrical conductors are adopted to make electrical contact with ground potential. Electrically conductive transfer tape may be coupled between the outer peripheral margins of each of the films and the adjacent electrical conductor to enhance the electrical contact therebetween. The glass unit is designed to attenuate electromagnetic radiation having frequencies in the range of 10 MHz to 10 GHz.
