Method of bonding sheet materials and coating compositions therefor

Claim 1

AN IMPROVED METHOD OF DESTRUCTIVELY DISTILLING OIL SHALE IN SITU BY USING A COMBUSTION WITH A RESIN WHICH IS AN ETHYLENE DIAMINE POLYAMIDE OF A MIXTURE OF TRIMERIC AND DIMERIC POLYSUPPORTING GAS CONTAINING CARBON DIOXIDE AND OXYGEN IN A CRITICAL RATIO WHICH COMPRISES ESMERIZED SOYBEAN OIL POLYENE FATTY ACID, THE RESIN HAVING A MOLECULAR WEIGHT BETWEEN ABOUT 3,000 TABLISHING A COMBUSTION WELL EXTENDING FROM THE SURFACE OF THE EARTH TO AN OIL SHALE STRUCTURE, ESTO 9,000 AND HEAT-SEALING CONTIGUOUS COATED SURFACES OF THE MATERIAL AT A TEMPERATURE BETWEEN TABLISHING AN EXHAUST WELL ADJACENT TO SAID COMBUSION WELL TO PERMIT WITHDRAWAL OF HYDROCARABOUT 90* TO 130* C. BONS DESTRUCTIVELY DISTILLED FROM OIL SHALE IN SAID STRUCTURE, PRODUCING AN EXPLODED ZONE AT THE BOTTOM OF SAID COMBUSTION WELL AND A COMBUSTION ZONE TO FACILITATE COMBUSTION OF HYDROCATBONS IN AND DESTRUCTIVE DISTILLATION FROM SAID OIL SHALE, EFFECTING COMBUSTION IN THE BOTTOM OF SAID COMBUSTION WELL WITH AN OXIDIZING GAS MIXTURE CONTAINING CARBON DIOXIDE AND OXYGEN, CONTROLLING THE OXYGEN-CARBON DIOXIDE RATIO SAID GAS MIXTURE IN SAID COMBUSTION WELL TO PROVIDE A CARBON DIOXIDE CONTENT ABOVE 20% IN SAID GAS MIXTURE AND TO PRODUCE A RELATIVELY LOW AND REGULATED TEMPERATURE BELOW ABOUT 1000* C. IN THE COMBUSTION ZONE AND ABOVE 400* C. AND BELOW ABOUT 600* C. IN THE ZONES OF DESTRUCTIVE DISTILLATION AND TO PRODUCE AN EXHAUST GAS IN THE EXHAUST WELL CONTAINING ABOVE 80% OF CARBON DIOXIDE THEREBY PROMOTING THE EVOLUTION OF HYDROCARBONS, WITHDRAWING SAID EXHAUST GAS CONTAINING VOLATILE HYDROCARBONS AND CARBON DIOXIDE FROM SAID EXHAUST WELL, AND RECOVERING SAID VOLATILE HYDROCARBONS WHEREBY GREATER YIELDS OF VOLATILE HYDROCARBONS ARE RECOVERED FROM SAID OIL SHALE WHILE AT THE SAME TIME THE SPENT SHALE IS PREVENTED FROM SLAGGING AND THE CINDER IS MAINTAINED POROUS TO SAID GAS MIXTURE.
