Appeal No. 95-1042
Application 07/964,002
application. Claims 31 and 46 are illustrative and read as
follows:
31. A method for making a flexible inorganic sintered sheet
or tape structure comprising the steps of:
a) mixing an inorganic powder with one or more vehicle
constituents to form a fluid batch;
b) forming the fluid batch on a fugitive polymer sheet
support into an elongated green sheet or tape preform of aspect
ratio greater than 2:1; and
c) sintering said green preform and support to vaporize the
support without damage to the preform and to sinter the inorganic
powder, thus to provide a flat sintered inorganic sheet or tape
structure of sufficient strength and flexibility to survive
bending in at least one direction to a radius of curvature not
exceeding about 20 centimeters without breakage.
46. A method in accordance with claim 31 wherein the step of
sintering the elongated green preform comprises continuously
transporting the elongated green preform through a hot zone
maintained at a temperature above the sintering temperature of
the inorganic powder.
