A METHOD FOR PRODUCING AN ACCURATE AND VARIABLE INTERVAL OF LAPSED TIME RELATED TO SOUND VELOCITY IN A GAS WHICH COMPRISES REPEATEDLY SCANNING TWO ANGULARLYSPACED LIGHT-SENSITIVE DEVICES BY A BEAM OF LIGHT ROTATED AT CONSTANT ANGULAR VELOCITY, CONVERTING FIRST ELECTRICAL PULSES INCIDENT TO SCANNING OF ONE OF SAID DEVICES TO SONIC PULSES APPLYING SAID SONIC PULSES AT ONE POINT OT THE GAS, CONVERTING SAID SONIC PULSES TO SECOND ELECTRICAL PULSES UPON ARRIVAL OF SAID SONIC PULSES AT ANOTHER POINT IN THE GAS, AND VARYING THE ANGLE BETWEEN SAID DEVICES IN SENSE DEPENDENT UPON WHETHER SAID SECOND ELECTRICAL PULSES OCCUR BEFORE OR AFTER THE SCANNING OF THE OTHER OF SAID DEVICES TO MATCH THE TIME INTERVAL BETWEEN THE CORRESPONDING PAIRS OF FIRST AND SECOND PULSES WITH THE TIME REQUIRED FOR THE SONIC PULSES TO TRAVERSE THE GAS BETWEEN SAID POINTS.
