Abstract: A door system (10) for a door opening defined by a pair of vertically spaced jambs (12), a header (13) positioned near the vertical extremity of the jambs (12), and a floor (F). The door system includes a door (D), a plurality of track sections (17-19), the door (D) being movable on the track sections (17-19), an exterior post (31) positioned forward of the door (D) and an interior post (32) positioned rearward of the door (D). The exterior and interior posts (31, 32) are adapted to oppose deflection of the door (D) during high wind conditions.

Abstract: A sol gel formulation and process for making thick coatings. In accordance with the teachings of this invention, sol gel coating layers of up to 300 microns in thickness can be provided in a single deposition.

Abstract: A composition for application to a substrate to form a an electrically conductive coating thereon. The composition includes a sol-gel solution filled with a conductive powder. The coating may be conductive or resistive depending on the application. A process is provided for applying such a coating by mixing a sol-gel solution with up to about 90% by weight of the solution of a conductive powder selected from the group consisting of ceramics, inter-ceramics, semi-conductors and metals so as to provide a uniform stable dispersion. The stable dispersion is applied to a substrate and the coated substrate is fired at a temperature sufficient to remove organic constituents and to produce at least a partially conductive film on the substrate. A heating device is also provided which is a product of the above process.
