Digital measuring device

Claim 1

A DIGITAL INTEGRATING SYSTEM RESPONSIVE TO THE MAGNITUDE OF A QUANTITY MEASURED IN FIRST UNITS AND PROVIDING THE MEASUREMENT INDICATION IN TERMS OF SECOND UNITS WHICH ARE OF A MAGNITUDE DIFFERENT THAN THE MAGNETUDE OF SAID FIRST UNITS, THE COMBINATION OF A GENERATOR FOR GENERATING ELECTRICAL PULSE SIGNALS AS A FUNCTION OF THE NUMBER OF SAID FIRST UNITS IN SAID QUANTITY, A MAIN COUNTER FOR TOTALIZING THE NUMBER OF COUNTER SIGNALS APPLIED THERETO, CIRCUIT MEANS CONNECTED TO SAID GENERATOR AND TO SAID MAIN COUNTER, SAID CIRCUIT MEANS NORMALLY SUPPLYING COUNTER SIGNALS TO SAID COUNTER IN A NUMBER WHICH BEARS A PREDETERMINED CONSTANT FIXED RATIO TO THE NUMBER OF SAID PULSE SIGNALS GENERATED BY SAID GENERATOR WHEREBY THE RATE OF TOTALIZING OF THE NUMBER OF SAID COUNTER OCCURS AS A FIXED CONSTANT FUNCTION OF THE NUMBER OF SAID PULSE SIGNALS GENERATED BY SAID GENERATOR, AND CONTROL MEANS CONNECTED TO SAID CIRCUIT TO DIFFERENCE THE NUMBER OF SAID COUNTER SIGNALS SUPPLIED TO SAID MAIN COUNTER FROM THE NUMBER OF SAID PULSE SIGNALS SUPPLIED TO SAID CIRCUIT MEANS BY SAID GENERATOR, SAID CONTROL MEANS BEING ACTUATED IN RESPONSE TO EACH ACCUMULATION OF A DESIREED NUMBER OF SAID PULSE SIGNALS GENERATED BY SAID GENERATOR, EACH SAID DESIRED NUMBER BEING SUBSTANTIALLY EQUAL TO THE NUMBER OF SAID ONE SIGNALS WHICH RESULTS IN AN ERROR OF NOT SUBSTANTIALLY GREATER THAN ONE IN THE TOTALIZATION OF SAID SECOND UNITS BY SAID COUNTER WHEREBY THE ERROR IN THE COUNT TOTALIZED BY SAID COUNTER IS MAINTAINED SUBSTANTIALLY WITHIN AN ERROR OF NOT SUBSTANTIALLY GREATER THAN PLUS OR MINUS ONE COUNT.
