Abstract: Multipane, insulating glazing structures (10) having exceptional thermal insulation performance are provided. The novel multipane structures (10) comprise two substantially parallel rigid glazing sheets (14 and 16) spaced apart by an interior spacer (22) of a low thermal conductivity, closed cell, foamed polymer. In a preferred embodiment, the glazing sheets (12, 14, 16 and 18) are present in a four-pane structure (10) filled with an inert gas and sealed with a gas-impermeable, continuous tape (46) overlaying a curable, high modulus sealant (44). Methods for manufacturing the novel glazing structures (10) are disclosed as well.

Abstract: Apparatus (10) for sputter depositing a layer of metal onto a latterally extended substrate (12) includes a substrate support, a deposition station (14), a downstream sensing assembly (58) and a computerized controller. The deposition station includes a cathode (16, 22) and anodes (28, 30) extending the width of the substrate (12). Gas supply is provided to each of a plurality of zones through a common distribution chamber (48) with a plurality of inlets which in combination cover the width of the substrate on which a thin film layer is to be deposited. The gas flow is directed through each anode into the plasma region and is individually controlled for each zone. The downstream sensing assembly (58) includes, for each zone, a four-point contact assembly (62) using four electrically conductive wheels (64, 66, 68, 70). Two of the wheels are used to apply current to the thin film and two are used to sense the resistance of it. This information is fed into the computer for use in controlling the gas flow into the deposition station, by zone.
