Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
95 words
A module for application to a furnace or oven wall to reduce the thermal inertia thereof, such module being made up of refractory fibers disposed with their axes aligned at right angles to the plane of the module so that they are end-on to the furnace or oven wall, the fibers of said module being totally wrapped and held in elastic compression by a wrapping of thermally combustible material which on first firing of the furnace or oven after application of the modules, is thermally destroyed so that the module is released from the compression.
Claim 2
Dependent Claim
95 words
A module for application to a furnace or oven wall to reduce the thermal inertia thereof, such module being made up of refractory fibers disposed with their axes aligned at right angles to the plane of the module so that they are end-on to the furnace or oven wall, the fibers of said module being totally wrapped and held in elastic compression by a wrapping of thermally combustible material which on first firing of the furnace or oven after application of the modules, is thermally destroyed so that the module is released from the compression.
Claim 3
Dependent Claim
14 words
A module according to claim 1 wherein the said material is a netting wrap.
Claim 4
Dependent Claim
12 words
A module according to claim 1 wherein the fibers are ceramic fibers.
