Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
58 words
An article of manufacture, a transparent glazing element comprising, a transparent sheet of glass having a smooth continuous surface, and a continuous abrasion resistant transparent reflective film of chromium silicide adhered to said smooth continuous surface, said chromium silicide film consisting essentially of chromium and silicon and being of a thickness of from about 200 to 1,000 Angstroms.
Claim 2
Dependent Claim
58 words
An article of manufacture, a transparent glazing element comprising, a transparent sheet of glass having a smooth continuous surface, and a continuous abrasion resistant transparent reflective film of chromium silicide adhered to said smooth continuous surface, said chromium silicide film consisting essentially of chromium and silicon and being of a thickness of from about 200 to 1,000 Angstroms.
Claim 3
Independent Claim
55 words
The method of making a transparent glazing element comprising, providing a transparent sheet of glass having a smooth continuous surface, and sputter-coating on said smooth continuous surface a continuous abrasion resistant transparent reflective film of chromium silicide consisting essentially of chromium and silicon and being of a thickness of from about 200 to 1,000 Angstroms.
Claim 4
Independent Claim
55 words
The method of making a transparent glazing element comprising, providing a transparent sheet of glass having a smooth continuous surface, and sputter-coating on said smooth continuous surface a continuous abrasion resistant transparent reflective film of chromium silicide consisting essentially of chromium and silicon and being of a thickness of from about 200 to 1,000 Angstroms.
Claim 5
Dependent Claim
29 words
The method of claim 2, wherein the chromium silicide is sputter-coated on the smooth continuous surface of the glass sheet in a low pressure atmosphere containing an inert gas.
Claim 6
Dependent Claim
43 words
The method of claim 2, wherein the sputter-coating involves ion bombarding a target of chromium silicide in a low-pressure gaseous atmosphere to cause atomic particles of the chromium silicide to be dislodged and deposited on the smooth continuous surface of the glass sheet.
Claim 7
Dependent Claim
90 words
In the method of making a transparent glazing element comprising a transparent sheet of glass having a smooth continuous surface and a continuous abrasion resistant reflective film adhered to said smooth continuous surface, the improvement which comprises providing a sputtering target of chromium silicide consisting essentially of chromium and silicon, and sputtering said chromium silicide from said target in a low-pressure atmosphere containing an inert gas onto said smooth continuous surface of the glass sheet to form a transparent film having a thickness of from about 200 to 1,000 Angstroms.
Claim 8
Dependent Claim
90 words
In the method of making a transparent glazing element comprising a transparent sheet of glass having a smooth continuous surface and a continuous abrasion resistant reflective film adhered to said smooth continuous surface, the improvement which comprises providing a sputtering target of chromium silicide consisting essentially of chromium and silicon, and sputtering said chromium silicide from said target in a low-pressure atmosphere containing an inert gas onto said smooth continuous surface of the glass sheet to form a transparent film having a thickness of from about 200 to 1,000 Angstroms.
