Claim 1
Independent Claim
191 words
AN ELECTRICAL COMPUTING MEASURING APPARATUS COMPRISING IN COMBINATION A RESISTANCE NETWORK CONSISTING OF FIRST AND SECOND LINEAR SLIDEWIRES EACH PROVIDED WITH A TAP, THE PHYSICALLY ADJUSTABLE ELEMENTS OF SAID SLIDEWIRES BEING GANGED BY A LINEAR MECHANICAL COUPLING, FIRST CONDUCTIVE MEANS CONNECTED BETWEEN ONE END OF SAID FIRST SLIDEWIRE AND ONE END OF SAID SECOND SLIDEWIRE, AND SECOND CONDUCTIVE MEANS CONNECTED BETWEEN THE OTHER ENDS OF SAID SLIDEWIRES, A CURRENT SOURCE CONNECTED TO SAID RESISTANCE NETWORK THROUGH TWO JUNCTIONS, ONE JUNCTION BEING THE TAP OF SAID FIRST SLIDEWIRE THE OTHER JUNCTION BEING AN LOCATION IN SAID RESISTANCE NETWORK OTHER THAN THE SLIDEWIRE TAPS AND SAID SECOND SLIDEWIRE, THE CURRENT SUPPLIED BY SAID COURCE BEING SUBSTANTIALLY INDEPENDENT IN MAGNITUDE FOR ALL VARIATIONS OF RESISTANCE OF SAID RESISTANCE NETWORK, AND A TRENSDUCER CONNECTED IN SERIES WITH A VOLTAGENULL DETECTOR IN ELECTRICAL OPPOSITION TO SAID RESISTANCE NETWORK AT TWO POINTS, ONE POINT BEING THE TAP OF SAID SECOND SLIDEWIRE, THE OTHER POINTS BEING NOT LOCATED IN SAID RESISTING NETWORK OTHER THAN THE SILDEWIRE TAPS AND SAID FIRST SLIDEWIRE, SAID TRANSDUCER DEVELOPING AN OUTPUT E. M. F. AS A QUADRATIC FUNCTION OF A PHENOMENON UNDER DETERMINATION.
