Abstract
Abstract PCT No. PCT/US82/01036 Sec. 371 Date Jul. 29, 1982 Sec. 102(e) Date Jul. 29, 1982 PCT Filed Jul. 29, 1982.A process is disclosed for developing a coating film on a surface of a sheet of glass. Generally the sheet of glass is heated to a temperature in the range of 510 DEG -625 DEG C. The process is characterized by the step of engaging the surface of the heated glass sheet with a powder spray composition. The powder spray composition comprises a plurality of hollow, generally spherical particles. Each of the particles is formed from heat decomposable, organo-metallic salts of at least two metals. Preferred teachings indicate that the organo-metallic salts are salts of cobalt, iron and chromium.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
74 words
A process for developing a coating film on a surface of a sheet of glass, the sheet of glass being at a temperature in a range of 510°-625° C., which process is characterized by the step of: engaging the surface of the heated glass sheet with a spray powder composition which comprises a plurality of hollow, generally spherical particles, each particle generally being formed from heat decomposable, organo-metallic salts of at least two metals.
Claim 2
Dependent Claim
74 words
A process for developing a coating film on a surface of a sheet of glass, the sheet of glass being at a temperature in a range of 510°-625° C., which process is characterized by the step of: engaging the surface of the heated glass sheet with a spray powder composition which comprises a plurality of hollow, generally spherical particles, each particle generally being formed from heat decomposable, organo-metallic salts of at least two metals.
