  • Patent number: 7180489
    Abstract: A window assembly includes a window frame defining a frame perimeter and at least one window mounted in the frame. A media panel incorporating a video display is associated with the window assembly and can be moved selectively into the frame perimeter for displaying video information and out of the frame perimeter for storage when not in use. A motorized transport mechanism is coupled to the media panel for selectively and automatically moving the media panel between its storage and operational positions.

  • Patent number: 6763875
    Abstract: An insect screen that includes a rigid frame defining a frame perimeter and a metal screen located within the rigid frame perimeter. The metal screen has a plurality of metal elements with a dark mat surface. The metal elements have a width of about 0.001 inch to about 0.0015 inch.

  • Patent number: 6680090
    Abstract: A complex profile made of a composite comprising a polyolefin polymer and a wood fiber. The composite is useful in conventional structural applications. The profile can be used in residential and commercial structures. The profile is used in the manufacture of the fenestration components such as windows and doors. The profile is designed with a cross-sectional shape to form structural elements in the fenestration units that possess sufficient strength, thermal stability and weatherability. The member comprises a hollow cross-section with at least one structural web or one fastener web. The profile can have a visible capstock layer and can be assembled using thermal welding processes.

  • Publication number: 20010051243
    Abstract: An improved composite structural member comprising a complex profile structural member, made of a composite comprising a polypropylene polymer and a wood fiber. The material is useful in conventional construction applications. The complex profile, in the form of an extruded thermoplastic composite member can be used in residential and commercial structures as described. Preferably, the structural member is used in the manufacture of the fenestration components such as windows and doors. Such linear members are designed with specifically configured cross-sectional shapes to form structural elements in the fenestration units. Structural elements must possess sufficient strength, thermal stability and weatherability to permit the manufacture of a structurally sound window unit that can be easily installed into a rough opening but can maintain its attractive appearance and structural integrity over the life of the window unit often twenty years or more.

  • Patent number: 6280667
    Abstract: The invention relates to polymer/wood fiber composite structural members that can be manufactured in an extrusion process engineered to produce the highest quality materials. The composite can be in a linear extrudate or pellet and can have a cross-section of any arbitrary shape, or can be a regular-geometric or of arbitrary-amorphous shape. The extruded material comprises a consistent proportion of polymer, wood fiber and water. During the extrusion, water is removed intentionally to dry the material to a maximum water content of less than about 10 wt-% based on the pellet weight. To make a structural unit, the pellet is introduced into an extruder apparatus wherein, under conditions of controlled mass throughput, shear, mechanical energy input, controlled temperature and pressure, the composite material is produced.
