the manner proposed by the examiner, and that MacKay is
nonanalogous art and therefore is improperly considered.
Jasper discloses a traveling wave tube in which a super-
conducting circuit is formed upon a substrate. Superconductor
material is applied in a pattern to the substrate by the
technique of plasma spraying and becomes fused to the substrate.
The examiner has acknowledged that the material deposited by the
plasma spraying is an oxide, which would indicate that a
subsequent oxidation process is not necessary, and none is taught
in this reference.
Ashok is directed to the manufacture of superconducting
structures and teaches depositing a superconductor material upon
a moving belt by means of an atomizer nozzle in which pressurized
gas is used as a vehicle for moving a molten stream of metal.
The resulting product is a continuous strip or a series of broken
strips (Figures 2 and 3; column 4, lines 13 through 17). The
required oxidation of the superconductor material can be
accomplished either by atomizing it in an oxidizing atmosphere or
oxidizing it after deposition on the moving belt (Abstract).
MacKay discloses an apparatus for dispensing liquid metals
in small controlled volumes upon such items as an electronic
substrate in drops (Figure 1) or in strips (Figure 4) for use in
