  • Patent number: 6671080
    Abstract: An electrochromic window assembly is disclosed that includes a first substrate and a second substrate that is maintained in a parallel and spaced relation from the first substrate by means of a window frame and spacer. The window assembly further includes an electrochromic device mounted within the airtight chamber formed between the first and second substrates. Electrochromic device 22 may be mounted so as to provide an air chamber between first substrate 12, which is the external substrate, and electrochromic device 22. At least one of the chambers formed between substrates 12 and 14 and electrochromic device 22 may be filled with an insulating gas such as argon. Also disclosed are novel methods for manufacture of an electrochromic device for incorporation into such a window assembly. A novel electrochromic device is also disclosed having electrical bus clips secured about the entire periphery of the electrochromic device. Also disclosed is the use of steel bus clips for the electrochromic device.

  • Patent number: 6167676
    Abstract: A freestanding portable partition panel system is provided for open office spaces and the like. Each panel includes a skeleton-like frame having two vertical uprights positioned adjacent opposite side edges thereof, and at least two pairs of horizontal stringers attached to the outer faces of the uprights in a vertically spaced-apart relationship to rigidly interconnect the same. One or more horizontal rows of slots are defined in each of the stringers. Cover panels are detachably mounted thereon to provide ready access to the frame. The cover panels permit access to the slots, and special off-module connectors with hooks for engaging the slots are provided for interconnecting adjacent panels in off-module positions. The hooks of the connectors are engaged with selected slots to hold a first partition panel perpendicular to a second partition panel in an off-module position on its face.
