Title: Process for coating glass surface
Inventor: GRUNDY BARRY THOMAS
IPC: C03C17/245
Filed: 1989-10-12
Abstract: A process for coating a moving ribbon of hot glass by chemical vapour deposition comprises establishing a first flow of a first reactant gas along the hot glass surface substantially parallel to the direction of movement of the glass, establishing a second flow of a second reactant gas as a turbulent flow at an angle to the glass surface, introducing said second flow into said first flow at said angle, while avoiding upstream flow of said second reactant gas in said first flow, directing the combined gas flow along the surface of the hot glass as a turbulent flow, and thereafter withdrawing the used coating gas away from the hot glass. The process enables a substantially uniform coating over 200 nm thick to be deposited in a short coating zone, and is useful for applying metal oxide coatings, for example fluorine doped tin oxide coatings, to hot glass.

Abstract: Absorbent article such as disposable diapers, incontinent briefs, diaper holders and the like, that have improved dynamic fit as well as containment characteristics. The elastic waist feature preferably comprises an interconnecting panel zone, a first flexural hinge zone joining the interconnecting panel zone with the containment assembly, an elasticized waistband, and a second flexural hinge zone joining the elasticized waistband with the interconnecting panel zone. The elasticized waistband comprises a shaping panel zone; a waistline panel zone; and a predisposed, resilient, waistband flexural hinge zone joining the shaping panel zone and the waistline panel zone. The waistband flexural hinge zone is predisposed to allow the panel zones to flexurally bend about a defined axis or zone and is resilient to provide a restoring force/moment that returns the panel zones to their preceeding in-use configuration, especially when the elasticized waistband has been pretensioned by a closure system. The closure system dynamically creates/maintains lateral tension through the elasticized waistband thereby allowing the elasticized waistband to more dynamically expand and contract with the motions of the wearer. The absorbent article additionally preferably comprises a pair of elasticized side panels disposed in the second waist region. The elasticized side panels preferably comprise a "zero strain" stretch laminate and an extension panel. The present invention also relates to alternative waist features comprising "an expansive tummy panel" elasticized waistband.
