Apparatus for volumetric measurements
First Claim
1. IN AN APPARATUS FOR VOLUMETRIC MEASUREMENTS COMPRISING A CONTAINER, A MEANS FOR CREATING A PRESSURE IN SAID CONTAINER, A PRESSURE GAUGE CONNECTED TO SAID CONTAINER AND TO SAID PRESSURE CREATING MEANS THEREFOR, AND A CLAMPING MEANS FOR CLOSING SAID CONTAINER, THE IMPROVEMENTS COMPRISING, IN COMBINATION, A THICK-WALLED CONTAINER, A COVER FOR SAID CONTAINER, SAID COVER HAVING A GROOVE ON THAT PORTION OF ITS SURFACE CONTACTING THE TOP SURFACE OF SAID CONTAINER WALLS, A FLEXIBLE GASKET POSITIONED IN SAID GROOVE CONTACTING THE TOP SURFACE OF THE CONTAINER WALLS, SAID GROVE BEING OF A VOLUME AT LEAST EQUAL TO THE VOLUME OF SAID GASKET, WHEREBY SAID GASKET CANNOT BE COMPRESSED BEYOND ITS ELASTIC LIMIT, THEREBY PREVENTING PERMANENT DEFORMATION OF SAID GASKET, A USHAPED ARM SUPPORT INTEGRAL WITH SAID COVER AND LATERALLY OPEN WITH RESPECT TO SAID CONTAINER WALLS, AND A FIRST MEANS PROJECTING BENEATH SAID CONTAINER AND POSITIONED OPPOSITE TO SAID COVER FOR PRODUCING A CLAMPING FORCE BY SAID CONTAINER AGAINST SAID COVER GREATER THAN THAT NECESSARY FOR COMPRISING THE SAID GASKET BETWEEN THE CONTAINER WALLS AND SAID COVER, SAID FIRST MEEANS INCLUDING A VERTICALLY MOVABLE FLEXIBLE PLATE HAVING A HOLLOW CUP-SHAPED UPPER PORTION AND PERIPHERAL PORTIONS FORMING THE WALLS OF SAID CUP-SHAPED UPPER PORTIONS SAID PERRIPHERAL PORTIONS BEING IN CONTACT WITH THE BASE PORTION OF SAID CONTAINER AT POINTS THEREON OPPOSITE TO SAID GASKET POSITIONED IN SAID GROVE OF SAID COVER, SAID FIRST MEANS BEING INTEGRAL WITH SAID SUPPORT AND INCLUDING A SECOND MEANS FOR PRODUCING A FLEXIBLE DEFORMATION OF SAID PORTION OF SAID FIRST MEANS, WHEREBY THE CONTAINER IS TIGHTLY CLOSED BY SAID COVER AND IS NEGLIGIBLY DEFORMED.
