Process for making carbon articles

Claim 1

A PROCESS FOR MAKING CARBONACEOUS ARTICLES COMPRISING FORMING AN ELECTRICALLY CONDUCTIVE DRY MIXTURE CONTAINING CARBONACEOUS MATERIALS CONSISTING OF FROM 8 TO 16 PARTS BY WEIGHT OF CARBON AND OF 50 TO 100 PARTS BY WEIGHT OF GRAPHITE PARTICLES, TOGETHER WITH FROM 22 TO 35 PARTS BY WEIGHT OF A LIQUEFIABLE BINDER MATERIAL CAPALE OF POLYMERIZING AT A TEMPRATURE BELOW 400* C. AND 6 TO 25 PERCENT BY WEIGHT OF SAID BINDER OF FINELY DIVIDED ELEMENTAL SULFUR, PLACING SAID MIXTURE IN A MOLD WHILE AT A TEMPERATURE BELOW THE LIQUEFYING TEMPERATURE OF SAID BINDER, SUBJECTING SAID MIXTURE TO A PRESSURE RANGING FROM 500 TP 1200 POUNDS PER SQUARE INCH TO COMPRESS THE SAME, AND DIECREASE THE VOLUME THEREOF BY THE REMOVAL OF AIR ENTRAPPED THEREIN, THEN INCREASING THE TEMPERATURE OF SAID MIXTURE WHILE MAINTAINING SAID PRESSURE THEREON BY PASSING CURRENT THERETHROUGH TO RAISE THE TEMPERATURE THEREOF TO A TEMPERATURE AT WHICH SAID BINDER MATERIAL BECOMES THERMOSET BUT NOT CARBONIZED, SHUTTING OFF SAID CURRENT WHEN SAID TEMPERATURE HAS BEEN REACHED, ALLOWING THE FORMED ARTICLE TO COOL WHILE IN SAID MOLD, REMOVING SAID FORMED ARTICLE FROM SAID MOLD WHEN SAID PRESSURE FALLS BELOW ABOUT 500 POUNDS PER SQUARE INCH, AND BAKING SAID FORMED ARTICLE TO AT LEAST A CARBONIZING TEMPERATURE.
