Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
72 words
THE METHOD OF MAKING INSULATION WHICH INCLUDES SQUEEZING OUT A MAJOR PORTION OF THE GAS IN A PERMEABLE RESILIENT MATERIAL CONTAINING A GAS AND REPLACING SAID GAS WITH A SECOND GAS HAVING BETTER INSULATING PROPERTIES AS THE RESILIENT MATERIAL REEXPANDS, AND WHILE RETAINING THE INSULATING GAS IN SAID RESILIENT MATERIAL APPLYING A SEALING COATING COMPLETELY AROUND SAID RESILIENT MATERIAL SUFFICIENT IN AMOUNT TO SEAL IN THE GAS HAVING THE BETTER INSULATING PROPERTIES.
Claim 2
Independent Claim
72 words

Claim 3
Dependent Claim
72 words
APPARATUS FOR MAKING RESILIENT INSULATION CONTAINING A GAS HAVING GOOD INSULATING PROPERTIES WHICH INCLUDES MEANS FOR SQUEEZING A FIRST GAS OUT OF RESILIENT INSULATION AND THEN REDUCING THE SQUEEZING OF THE INSULATION, MEANS FOR INTRODUCING A SECOND GAS HAVING BETTER INSULATING PROPERTIES INTO THE INSULATION AS THE SQUEEZING IS REDUCED, AND MEANS FOR APPLYING LIQUID FOAM FORMING MATERIALS AROUND SAID RESILIENT INSULATION TO SEAL IN THE SECOND GAS WITHIN THE RESILIENT INSULATION.
Claim 4
Dependent Claim
