Measurement of change in weight

Claim 1

APPARATUS FOR MEASURING THE CHANGE IN WEIGHT OF A SORBANT COMPRISING IN COMBINATION: AN ENCLOSED CHAMBER, A SOURCE OF TEST GAS, MEANS FOR ADMITTING SAID GAS TO SAID CHAMBER AT ANY DESIRED PRESSURE SO AS TO CHANGE THE INTERNAL ENVIRONMENT OF SAID CHAMBER, A CONTAINER FOR HOLDING SAID SORBANT WITHIN SAID CHAMBER, FIRST RESILIENT SUPPORT MEANS FOR SUPPORTING SAID CONTAINER, FIRST TRANSFORMER CORE SUPPORTED BY SAID RESILIENT MEANS, A FIRST TRANSFORMER HAVING A PRIMARY AND A SECONDARY COIL SURROUNDING SAID CORE, A TARE SUBSTANTIALLY INDENTICAL TO SAID CONTAINER, SECOND RESILIENT SUPPORT MEANS FOR SUPPORTING SAID TARE, A SECOND TRANSFORMER CORE SUPPORTED BY SAID SECOND RESILIENT MEANS A SECOND TRANSFORMER HAVING A PRIMARY AND A SECONDARY COIL SURROUNDING SAID SECOND CORE, MEANS FOR IMPRESSING A SUBSTANTIALLY CONSTANT AND EQUAL POTENTIAL ONTO SAID PRIMARY COILS OF SAID FIRST AND SECND TRANSFORMERS, MEANS ELECTRICALLY CONNECTED BETWEEN SAID SECONDARY COILS OF SAID FIRST AND SECOND TRANSFORMERS FOR GENERATING A SIGNAL WHICH IS A FUNCTION OF THE CHANGE IN RESULTANT OUTPUT OF SAID SECONDARY COILS, MOTOR MEANS FOR MOVING SAID SECOND TRANSFORMER IN RESPONSE TO SAID SIGNAL, MEANS FOR MEASURING THE DISTANCE SAID SECOND TRANSFORMER HAS BEEN MOVED WHEREBY THE DISTANCE WHICH SAID SECOND TRANSFORMER IS MOVED IS A MEASURE OF THE CHANGE IN WEIGHT OF SAID ADSORBANT MATERIAL, AND ERRORS CAUSED BY THE BUOYANCE EFFECT OF CHANGING PRESSURE OR THE EFFECT OF CHANGING TEMPERATURE ARE COMPENSATED FOR.
