Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
102 words
A COMPOSITE MULTI-LAYERED INSULATION FOR USE IN A VACUUM SPACE BETWEEN WARM AND COLD BOUNDARIES COMPRISING PERMANENTLY PRECOMPACTED LOW-CONDUCTIVE LAYERS OF (1) FIBERS HAVING DIAMETERS LESS THAN ABOUT 20 MICRONS FOR REDUCING HEAT TRANSFER BY CONDUCTION, BEING ORIENTED SUBSTANTIALLY PERPENDICULAR TO THE DIRECTION OF HEAT INLEAK ACROSS THE VACUUM SPACE; (2) FINELY DIVIDED RADIANT HEAT REFLECTING BODIES OF SIZES LESS THAN ABOUT 500 MICRONS HAVING METALLIC SURFACES, BEING INCORPORATED IN AND UNIFORMLY DISPERSED THROUGH THE LAYERS IN AN AMOUNT BETWEEN ABOUT 10% AND 60% BY WEIGHT OF THE LAYERS; AND (3) A BINDER FOR CEMENTING THE HEAT REFLECTING BODIES TO SAID FIBERS.
