Chemical reaction apparatus

Claim 1

AN APPARATUS FOR THE CONTROLLED REACTION OF COMMINUTED SOLIDS AND A VOLATILE LIQUID REAGENT, COMPRISING A REACTION CHAMBER, A REFLUX CONDENSER, A VAPOR LINE AND A LIQUID REFLUX LINE BOTH CONNECTING THE SAID REACTION CHAMBER AND REFLUX CONDENSER, A VENT LINE COMMUNICATING WITH THE REACTION CHAMBER FOR VENTING GASES THREFROM, A MOTORED VENT VALVE THEREIN FOR CONTROL OF VENTING, A LIQUID REAGENT FEED LINE COMMUNICATING WITH THE REACTION CHAMBER FOR FEED OF REAGENT THERETO AND A MOTORED VALVE THEREIN FOR CONTROL OF LIQUID REAGENT FEED, A PRESSURE GUAGE CONNECTED TO THE REACTION SPACE FOR MEASURING THE PRESSURE THEREIN AND A PRIMARY CONTROL MEANS OPERATIVELY CONNECTED TO THE PRESSURE GUAGE, SAID CONTROL MEANS INCLUDING A PRESSURE SET POINT MECHANISM AND A PRESSURE RISE TIMER ENGAGEABLE THEREWITH AND ADAPTED TO RAISE THE PRESSURE SET POINT THROUGH A RISING PRESSURE PATH TO A PRESELECTED PRESSURE DURING AN INITIAL TIME PERIOD, AND A HOLD TIMER ADAPTED TO MAINTAIN THE PRESSURE SET POINT MECHANISM AT SAID PRESELECTED RESSURE FOLLOWING THE SAID INITIAL TIME PERIOD, AND A CONTROLLER RESPONSIVE TO ANY DIFFERENCE BETWEEN THE SET POINT PRESSURE AND THE ACTUAL PRESSURE MEASURED BY THE PPRESSURE GAUGE AND OPERATIVELY CONNECTED TO THE MOTORED VALVE IN THE LIQUID REAGENT FEED LINE FOR OPENING SAID VALVE WHEN THE SETPOINT PRESSURE EXCEEDS THE ACTUAL PRESSURE AND CLOSING THE VALVE WHEN THE ACTUAL PRESSURE EXCEEDS THE SET POINT PRESSURE.

Claim 2

AN APPARATUS FOR THE CONTROLLED REACTION OF COMMINUTED SOLIDS AND A VOLATILE LIQUID REAGENT, COMPRISING A REACTION CHAMBER, A REFLUX CONDENSER, A VAPOR LINE AND A LIQUID REFLUX LINE BOTH CONNECTING THE SAID REACTION CHAMBER AND REFLUX CONDENSER, A VENT LINE COMMUNICATING WITH THE REACTION CHAMBER FOR VENTING GASES THREFROM, A MOTORED VENT VALVE THEREIN FOR CONTROL OF VENTING, A LIQUID REAGENT FEED LINE COMMUNICATING WITH THE REACTION CHAMBER FOR FEED OF REAGENT THERETO AND A MOTORED VALVE THEREIN FOR CONTROL OF LIQUID REAGENT FEED, A PRESSURE GUAGE CONNECTED TO THE REACTION SPACE FOR MEASURING THE PRESSURE THEREIN AND A PRIMARY CONTROL MEANS OPERATIVELY CONNECTED TO THE PRESSURE GUAGE, SAID CONTROL MEANS INCLUDING A PRESSURE SET POINT MECHANISM AND A PRESSURE RISE TIMER ENGAGEABLE THEREWITH AND ADAPTED TO RAISE THE PRESSURE SET POINT THROUGH A RISING PRESSURE PATH TO A PRESELECTED PRESSURE DURING AN INITIAL TIME PERIOD, AND A HOLD TIMER ADAPTED TO MAINTAIN THE PRESSURE SET POINT MECHANISM AT SAID PRESELECTED RESSURE FOLLOWING THE SAID INITIAL TIME PERIOD, AND A CONTROLLER RESPONSIVE TO ANY DIFFERENCE BETWEEN THE SET POINT PRESSURE AND THE ACTUAL PRESSURE MEASURED BY THE PPRESSURE GAUGE AND OPERATIVELY CONNECTED TO THE MOTORED VALVE IN THE LIQUID REAGENT FEED LINE FOR OPENING SAID VALVE WHEN THE SETPOINT PRESSURE EXCEEDS THE ACTUAL PRESSURE AND CLOSING THE VALVE WHEN THE ACTUAL PRESSURE EXCEEDS THE SET POINT PRESSURE.
