Abstract
Abstract An inorganic titanium coating believed to be a titanium oxide coating is applied to a glass surface by exposing the surface at elevated temperature, desirably at least 300*F., to a liquid comprising a titanium oxychloride of the formula Ti(OH)xCl(4 x) wherein x is 1, 2 or 3, for example an aqueous solution of a titanium oxychloride. The process is especially useful for providing the ''''hot end coating'''' of a dual protective coating for glass containers comprising an inorganic ''''hot end coating'''' and a lubricious organic ''''cold end coating''''.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
79 words
IN A METHOD FOR APPLYING AN IN-ORGANIC TITANIUM-CONTAINING COATING TO A GLASS SURFACE COMPRISING EXPOSING SAID SURFACE TO A THERMALLY-DECOMPOSABLE TITANIUM COMPOUND AT AN ELEVATED TEMPERATURE SUFFICIENT TO CAUSE THERMAL DECOMPOSITION OF SAID COMPOUND TO FORM SAID COATING, THE IMPROVEMENT WHEREIN SAID COATING IS FORMED BY SPRAYING ONTO SAID SURFACE A FINELY DIVIDED DILUTE AQUEOUS SOLUTION OF TITANIUM OXYCHLORIDE OF THE FORMULA TI(OH)XCL(4-X), WHEREIN X IS 1, 2, OR 3, SAID TEMPERATURE RANGING FROM ABOUT 300F. TO ABOUT 800*F.

Claim 3
Dependent Claim
27 words
The method according to claim 1 wherein the concentration of said titanium oxychloride in said solution is up to about 4 weight percent, calculated as titanium tetrachloride.
Claim 4
Dependent Claim
29 words
The method according to claim 1 wherein the degree of atomization of said spray is sufficient to provide at least 4000 droplets per square inch at the glass surface.
Claim 5
Dependent Claim
107 words
IN A METHOD FOR IMPARTING IMPROVED SCRATCH RESISTANCE AND LUBRICITY TO A GLASS CONTAINER COMPRISING APPLYING AN INORGANIC TITANIUM-CONTAINING COATING AND A LUBRICOUS ORGANIC COATING TO THE OUTER SURFACE OF SAID CONTAINER, SAID TITANIUMCONTAINING COATING BEING FORMED BY APPLYING A THERMALLYDECOMPOSABLE COMPOUND TO THE SURFACE OF SAID CONTAINER AT AN ELEVATED TEMPERATURE SUFFICIENT TO CAUSE THERMAL DECOMPOSITION OF SAID COMPOUNT TO FORM SAID COATING, THE IMPROVEMENT WHEREIN SAID INORGANIC COATING IS FORMED BY SPRAYING A FINELY DIVIDED DILUTE AQUEOUS SOLUTION OF A TITANIUM OXYCHLORIDE OF THE FORMULA TI(OH)XCL(4-X), WHEREIN X IS 1, 2, OR 3, ONTO SAID CONTAINER, SAID TEMPERATURE RANGING FROM ABOUT 300*F. TO ABOUT 800*F.

Claim 10
Dependent Claim
29 words
The method according to claim 4 wherein the degree of atomization of said spray is sufficient to provide at least 4000 droplets per square inch at the glass surface.
