Digitally averaged force measuring

Claim 1

IN A DIGITALLY AVERAGE FORCE MEASURING APPARATUS, A SUPPORT, A BEAM PIVOTED TO THE SUPPORT FOR VERTICAL MOVEMENT, A MASS FIXED TO THE BEAM, A SPRING YIELDINGLY SUPPORTING THE BEAM AND MASS HORIZONTALLY, A MIRROR MOUNTED TO PIVOT WITH THE BEAM, A LIGHT BEAM SOURCE ARRANGED JTO REFLECT A LIGHT BEAM FROM THE MIRROR, A LIGHT BEAM SPLITTER MOUNTED IN THE PATH OF THE REFLECTED LIGHT BEAM AND ARRANGED TO DIRECT THE REFLECTED LIGHT BEAM IN EITHER OF TWO DIRECTIONS UPON VERTICAL MOVEMENT OF THE PIVOTED BEAM, FIRST AND SECOND PHOTOCELLS MOUNTED TO RECEIVE THE REFLECTED LIGHT BEAM DIRECTED IN EITHER DIRECTION BY THE BEAM SPLITTER, A PULSE GENERATOR, FIRST AND SECOND REPULSION COILS MOUNTED IN ELECTROMAGNETIC RELATIONSHIP WITH THE MASS AND ARRANGED TO REPULSE THE MASS IN EITHER VERTICAL DIRECTION WHEN ENERGIZED WITH PULSES, A GATE CIRCUIT ELECTRICALLY INTERCONNECTING THE PULSE GENERATOR, PHOTOCELLS AND REPULSION COILS AND ARRANGED TO DIRECT PULSES FROM THE PULSE GENERATOR TO THE FIRST REPULSION COIL WHEN THE FIRST PHOTOCELL RECEIVES THE GREATER REFLECTED LIGHT AND DIREC PULSES FROM THE PULSES GENERATOR TO THE SECOND REPULSION COIL LIGHT, A COUNTER ELECTRICALLY CONNECTED TO THE REPULSION LIGHT, A COUNTER ELECTRICALLY CONNECTED TO THE REPULSION COILS AND ARRANGED TO ALGEBRAICALLY AVERAGE THE PULSES APPLIED TO THE REPULSION COILS, PRINTING MEANS ELECTRICALLY CONNECTED TO THE COUNTER AND ARRANGED TO PRINT THE ALGEBRAIC AVERAGE WHEN SAID PRINTING MEANS IS ACTIVATED, AN INTERVAL TIMER ELECTRICALLY CONNECTED TO THE COUNTER AND PRINTING MEANS AND ARRANGED TO ACTIVATE THE PRINTING MEANS AT INTERALS, AND A STEP MOTOR ELECTRICALLY CONNECTED TO THE COUNTER AND TIMER AND MECHANICALLY CONNECTED TO THE PIVOTED BEAM AND ARRANGED TO VERTICALLY MOVE THE PIVOTED BEAM AND MASS A DISTINCT STEP AT INTERVALS DETERMINED BY THE TIMER IN A DIRECTION TO COUNTERACT THE ALGEBRAIC AVERAGE INDICATED BY THE COUNTER, SAID PRINTING MEANS INTERCONNECTED THROUGH SAID COUNTER WITH THE STEP MOTOR AND ARRANGED TO PRINT THE OCCURRENCE AND DIRECTION OF THE STEP MOTOR BEAM MOVEMENT.
