    Abstract: A method of introducing a reducing gas and an inert gas into a glass forming chamber at a plurality of locations along the length of the chamber by means of a system which permits delivery of a mixture of the reducing and inert gases to all such locations, or delivery of only the inert gas at certain of the locations, in which a significantly greater proportion of the reducing gas is introduced into the service space above the bath proximate the inlet end thereof. The total amount of reducing gas which must be introduced to maintain a reducing bath atmosphere is minimized as a result of the location of such introduction. The present invention provides for a more conservative use of reducing gases such as hydrogen.

    Abstract: A process for the formation of an electrically conductive multi layer coating on the surface of a hot glass substrate by a pyrolytic deposition process is characterised in that the coating comprises at least one layer comprising silicon and oxygen at least one layer of an electrically conductive doped metal oxide and a protective layer of an inorganic material between these layers. Both the layer comprising silicon and oxygen and the layer of a doped metal oxide are deposited in the float bath. The protective layer of an inorganic material is deposited between the two layers. Preferably, the layer comprising silicon and oxygen has less than the stoichiometric amount of oxygen and the layer of doped metal oxide comprises fluorine doped tin oxide. Preferably, the protective layer of an inorganic material comprises silicon dioxide.

    Abstract: A method of forming a polymer backing on a glass substrate through the use of a pre-polymer powder applied onto the surface of the substrate. The backing is applied on-line in an existing substrate manufacturing or fabricating process while the substrate is at a high enough temperature to polymerize the powder. The resulting backed substrate is durable and abrasion resistant and exhibits excellent opacification and adhesion properties.
