Appeal No. 1996-2718
Application No. 08/221,207
i. the fiberizing gas has been heated to above 212EF, e.g., high pressure
steam (col. 2, lines 35-46);
ii. the fiberizing gas is blown at a rate sufficient to transform the dropped
material into fine ligaments which cool and solidify in the barrel to form flexible fibers (col. 3, lines 43-
65); and
e. collecting the fibers (col. 1, lines 10-35).
2. Walz does not teach:
a. the production of high temperature superconducting fibers;
b. the production of ceramic fibers;
b. heating the glass material in a furnace having a heating space;
c. with respect to present claim 6, the concept of dropping a stream of molten
superconductor in a collar in the furnace to maintain its temperature before the stream reaches the
barrel.
F. Bock is cited as a secondary reference for the first and second grounds of rejection under 35
U.S.C. ' 103.
1. Bock teaches:
a. a superconducting ceramic material such as a Bi-based material in which the
species Bi2Sr2Ca1Cu2O8 would fall (Abstract; col. 1, lines 11-30);
b. shaping Bi-based superconducting material by melting the material to
produce articles having superconducting properties (col. 1, lines 52-68).
2. Bock does not teach making the fiber form of superconducting material.
