Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
134 words
A METHOD OF ASSEMBLING AN ASSEMBLAGE COMPRISING TWO FULLY CURED HEAT-HARDENABLE RESIN BONDED MOULDINGS, SAID MOULDINGS EACH HAVING A PLURALITY OF SURFACES WHICH ARE TO BE ADHESIVELY JOINTED EACH TO A SURFACE ON THE OTHER MOULDING TO FORM THE ASSEMBLAGE, WHICH METHOD COMPRISES INTRODUCING BETWEEN EACH PAIR OF SURFACES A LAYER OF HEAT-HARDENABLE ADHESIVE AND BETWEEN ALL SAID SURFACES OF ONE MOULDING AND ALL SAID SURFACES OF THE OTHER MOULDING A PLURALITY OF THIN STRIP-LIKE ELECTRIC CONDUCTORS, SAID CONDUCTORS BEING ARRANGED WITH AT LEAST ONE CONDUCTOR BETWEEN EACH PAIR OF SAID SURFACES TO BE JOINTED AND NONE OF THE CONDUCTORS CROSSING ANY ONE OF THE CONDUCTORS AT ANY POINT, PRESSING SAID PAIRS OF SURFACES TOGETHER AND CAUSING ELECTRIC CURRENT TO PASS ALONG ALL SAID CONDUCTORS TO GENERATE SUFFICIENT HEAT TO HARDEN SAID HEAT-HARDENABLE ADHESIVE.
