Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
119 words
A METHOD OF DETERMINING THE EFFECT OF A SUBSTANCE UNDER INVESTIGATION ON CELLS COMPRISING TRANSMITTING A STREAM OF LIQUID CONTAINING SAID CELLS, A NUTRIENT FOR SAID CELLS, AND A PREDETERMINED QUANTITY OF SAID SUBSTANCE UNDER INVESTIGATION, FIRST THROUGH A ZONE IN WHICH CARBON DIOXIDE IS EVOLVED FROM SAID CELLS DURING THE FLOW OF SAID LIQUID STREAM AND THEREAFTER THROUGH A ZONE IN WHICH A QUANTITY OF THE EVOLVED CARBON DIOXIDE IS SEPARATED FROM THE LIQUID PHASE OF THE STREAM AND IS FORMED INTO A GASEOUS STREAM, INTRODUCING SAID GASEOUS STREAM INTO A STREAM OF LIQUID INCLUDING A COLOR REAGENT FOR THE CARBON DIOXIDE, AND COLORIMETRICALLY EXAMINING SAID LAST MENTIONED LIQUID STREAM AFTER THE INTRODUCTION THEREIN OF SAID GASEOUS STREAM.
Claim 2
Independent Claim
119 words
A METHOD OF DETERMINING THE EFFECT OF A SUBSTANCE UNDER INVESTIGATION ON CELLS COMPRISING TRANSMITTING A STREAM OF LIQUID CONTAINING SAID CELLS, A NUTRIENT FOR SAID CELLS, AND A PREDETERMINED QUANTITY OF SAID SUBSTANCE UNDER INVESTIGATION, FIRST THROUGH A ZONE IN WHICH CARBON DIOXIDE IS EVOLVED FROM SAID CELLS DURING THE FLOW OF SAID LIQUID STREAM AND THEREAFTER THROUGH A ZONE IN WHICH A QUANTITY OF THE EVOLVED CARBON DIOXIDE IS SEPARATED FROM THE LIQUID PHASE OF THE STREAM AND IS FORMED INTO A GASEOUS STREAM, INTRODUCING SAID GASEOUS STREAM INTO A STREAM OF LIQUID INCLUDING A COLOR REAGENT FOR THE CARBON DIOXIDE, AND COLORIMETRICALLY EXAMINING SAID LAST MENTIONED LIQUID STREAM AFTER THE INTRODUCTION THEREIN OF SAID GASEOUS STREAM.
Claim 3
Dependent Claim
107 words
APPARATUS FOR EXAMINING A LIQUID CULTURE OF LIVE CELLS, COMPRISING MEANS FOR FORMING A STREAM CONTAINING SAID LIQUID CULTURE OF THE CELLS, AN INCUBATOR HAVING AN INLET AND AN OUTLET, GAS AND LIQUID SEPARATOR IN FLOW-COMMUNICATION WITH SAID OUTLET OF SAID INCUBATOR, MEANS FOR TRANSMITTING SAID STREAM TO THE INLET OF SAID INCUBATOR AND FROM THE OUTLET THEREOF TO SAID GAS AND LIQUID SEPARATOR MEANS FOR THE SEPARATION FROM THE LIQUID OF CARBON DIOXIDE GAS EVOLVED FROM SAID STREAM DURING THE FLOW THEREOF MEANS FOR WITHDRAWING A STREAM OF SAID GAS FROM SAID SEPARATOR MEANS, AND MEANS FOR QUANTITATIVELY ANALYZING SAID STREAM IN RESPECT TO CARBON DIOXIDE.
Claim 4
Dependent Claim
107 words
APPARATUS FOR EXAMINING A LIQUID CULTURE OF LIVE CELLS, COMPRISING MEANS FOR FORMING A STREAM CONTAINING SAID LIQUID CULTURE OF THE CELLS, AN INCUBATOR HAVING AN INLET AND AN OUTLET, GAS AND LIQUID SEPARATOR IN FLOW-COMMUNICATION WITH SAID OUTLET OF SAID INCUBATOR, MEANS FOR TRANSMITTING SAID STREAM TO THE INLET OF SAID INCUBATOR AND FROM THE OUTLET THEREOF TO SAID GAS AND LIQUID SEPARATOR MEANS FOR THE SEPARATION FROM THE LIQUID OF CARBON DIOXIDE GAS EVOLVED FROM SAID STREAM DURING THE FLOW THEREOF MEANS FOR WITHDRAWING A STREAM OF SAID GAS FROM SAID SEPARATOR MEANS, AND MEANS FOR QUANTITATIVELY ANALYZING SAID STREAM IN RESPECT TO CARBON DIOXIDE.
