rejection of claims 37 and 43-66. 3
Claims 37, 43, 46, 47 and 59 are representative and are
reproduced below:
37. A plate of glass coated with a layer containing indium
and tin oxides having zones of a low emissivity and resistivity
of less than or equal to 0.15 and 3 x 10 ohm-cm, respectively -4
for a thickness of between about 1800 and 4500 angstroms with at
least one other zone wherein the emissivity and resistivity are
higher than 0.15 and 3 x 10 ohm-cm, respectively that is-4
produced by:
preparing a dry metal composition containing indium formate;
mixing at least a powdered or gaseous tin compound or a
gaseous organotin compound with the indium formate in proportions
ranging from one to thirty weight percent;
depositing said composition onto a surface of a heated
substrate with coating means so as to pyrolyze the composition;
and
heating the coated substrate to enhance the properties of
the layer.
43. A plate of glass coated with a pyrolyzed metal oxide
layer comprising indium oxide formed by depositing a
predetermined amount of an organic indium compound on a heated
substrate, thereby pyrolyzing the indium compound.
3The examiner’s final rejection inadvertently failed to
treat claim 37, which claim was specifically rejected in the
Answer and denoted as a new rejection. Appellants’ Reply Brief
and concurrently filed amendment were denied entry by the
examiner.
