Device for measuring phase angles between oscillations

Claim 1

A SYSTEM FOR DIGITAL MEASUREMENT OF THE PHASE ANGLE BETWEEN TWO OSCILLATIONS OF THE SAME FREQUENCY, COMPRISING A BISTABLE MULTIVIBRATOR SWITCHABLE BETWEEN CONDUCTIVE AND BLOCKED CONDITIONS UNDER CONTROL BY SEQUENTIAL CONTROL PULSES INDICATIVE OF THE RESPECTIVE PHASE POSITIONS OF THE FIRST AND SECOND OCILLATIONS RESPECTIVELY; A SOURCE OF HIGH-FREQUENCY PULSES; A DITIGAL PULSE COUNTER; A NORMALLY CLOSED GATE CONNECTED TO AND CONTROLLABLE BY AND SAID COUNTER AND CONNECTED TO AND CONTROLLABLE BY SAID MULTIVIBRATOR TO OPEN FOR PASSING A PULSE TRAIN FROM SAID SOURCE TO SAID COUNTER WHEN SAID MULTIVIBRATOR IS IN CONDUCTING CONDITION WHEREBY SAID COUNTER PROVIDES A MEASUREMENT OF THE PHASE ANGLE BETWEEN SAID FIRST AND SECOND OSCILLATIONS; REPETITION CONTROL MEANS CONNECTED WITH SAID MULTIVIBRATOR FOR REPEATING THE MEASUREMENT A PREDETERMINED NUMBER OF TIMES; A PHASE COMPARATOR CIRCUIT RESPONSIVE TO SAID FIRST AND SECOND OSCILLATIONS; AND AN ASTABLE MULTIVIBRATOR CONNECTED TO SAID PHASE COMPARATOR CIRCUIT AND CONTROLLED THEREBY AND CONNECTED WITH SAID BISTABLE MULTIVIBRATOR FOR PREVENTING THE INITIATION OF THE BLOCKED CONDITION OF SAID BISTABLE MULTIVIBRATOR UNTIL ARRIVAL OF THE CONTROL PULSE INDICATIVE OF THE PHASE POSITION OF SAID SECOND OSCILLATION AND PREVENTING THE INITIATION OF SAID CONDUCTIVE CONDITION UNTIL ARRIVAL OF THE CONTROL PULSE INDICATIVE OF THE PHASE POSITION OF SAID FIRST OSCILLATION AND FOLLOWING SAID SECOND OSCILLATION PULSE, WHEREBY MEASURING ERRORS AT VERY SMALL AND LARGE PHASE ANGLES ARE MINIMIZED.

Claim 2

A SYSTEM FOR DIGITAL MEASUREMENT OF THE PHASE ANGLE BETWEEN TWO OSCILLATIONS OF THE SAME FREQUENCY, COMPRISING A BISTABLE MULTIVIBRATOR SWITCHABLE BETWEEN CONDUCTIVE AND BLOCKED CONDITIONS UNDER CONTROL BY SEQUENTIAL CONTROL PULSES INDICATIVE OF THE RESPECTIVE PHASE POSITIONS OF THE FIRST AND SECOND OCILLATIONS RESPECTIVELY; A SOURCE OF HIGH-FREQUENCY PULSES; A DITIGAL PULSE COUNTER; A NORMALLY CLOSED GATE CONNECTED TO AND CONTROLLABLE BY AND SAID COUNTER AND CONNECTED TO AND CONTROLLABLE BY SAID MULTIVIBRATOR TO OPEN FOR PASSING A PULSE TRAIN FROM SAID SOURCE TO SAID COUNTER WHEN SAID MULTIVIBRATOR IS IN CONDUCTING CONDITION WHEREBY SAID COUNTER PROVIDES A MEASUREMENT OF THE PHASE ANGLE BETWEEN SAID FIRST AND SECOND OSCILLATIONS; REPETITION CONTROL MEANS CONNECTED WITH SAID MULTIVIBRATOR FOR REPEATING THE MEASUREMENT A PREDETERMINED NUMBER OF TIMES; A PHASE COMPARATOR CIRCUIT RESPONSIVE TO SAID FIRST AND SECOND OSCILLATIONS; AND AN ASTABLE MULTIVIBRATOR CONNECTED TO SAID PHASE COMPARATOR CIRCUIT AND CONTROLLED THEREBY AND CONNECTED WITH SAID BISTABLE MULTIVIBRATOR FOR PREVENTING THE INITIATION OF THE BLOCKED CONDITION OF SAID BISTABLE MULTIVIBRATOR UNTIL ARRIVAL OF THE CONTROL PULSE INDICATIVE OF THE PHASE POSITION OF SAID SECOND OSCILLATION AND PREVENTING THE INITIATION OF SAID CONDUCTIVE CONDITION UNTIL ARRIVAL OF THE CONTROL PULSE INDICATIVE OF THE PHASE POSITION OF SAID FIRST OSCILLATION AND FOLLOWING SAID SECOND OSCILLATION PULSE, WHEREBY MEASURING ERRORS AT VERY SMALL AND LARGE PHASE ANGLES ARE MINIMIZED.
