Controlled frequency power supply system

Claim 1

A SYSTEM FOR SUPPLYING CONSTANT FREQUENCY POLYPHASE POWER TO PLURAL PHASE POWER LOAD FROM A POLYPHASE A.C. POWER SOURCE OF VARIABLE FREQUENCY INCLUDING A GROUP OF SWITCH DEVICES IN EACH OF THE POWER PHASES LINES FOR DIRECTLY CONNECTING THE POWER PHASES TO THE LOAD PHASES, EACH OF SAID GROUPS CONTAINING A NUMBER OF SWITCHES EACH DIRECTLY CONNECTED TO A DIFFERENT ONE OF THE LOAD PHASES, A PULSE SOURCE POWERED BY SAID POWER SOURCE FOR OPERATING SAID SWITCHES HAVING A PLURALITY OF OUTPUTS AND PRODUCING AT EACH OUTPUT A TRAIN OF PLUSES HAVING A RECURRENCE FREQUENCY WHICH DIFFERS FROM THE POWER SOURCE FREQUENCY BY AN AMOUNT EQUAL TO THE DESIRED CONSTANT FREQUENCY, EACH OF SAID PULSE OUTPUTS BEING CONNECTED TO ONE SWITCH IN EACH OF SAID GROUPS TO CLOSE THE SWITCH IN RESPONSE TO A PULSE AND ALLOW THAT PORTION OF THE WAVEFORM THEN OCCURING TO FLOW TO A LOAD PHASE FOR THE DURATION OF THE PULSE THE SWITCHES CONNECTED TO THE SAME LOAD PHASE BEING CONNECTED TO DIFFERENT PULSE OUTPUTS, THE PULSES AT THE DIFFRENT PULSE OUTPUTS BEING DISPLACED IN PHASE BY AN AMOUNT SUCH THAT THE SWITCHES CONNECTED TO THE SAME LOAD PHASE ARE OPERATED TO SEQUENTIALLY CONNECT EACH POWER PHASE TO THE LOAD PHASE TO PRODUCE AT EACH LOAD PHASE A SERIES OF WAVEFORM PORTIONS HAVING AS A COMPONENT THEREOF THE DESIRED CONSTANT FREQUENCY, AND FREQUENCY DISCRIMINATING MEANS CONNECTED BETWEEN ONE OF THE LOAD PHASES AND THE PULSE SOURCE TO VARY THE PULSE RECURRENCE FREQUENCY TO MAINTAIN THE DESIRED CONSTANT FREQUENCY AT THE LOAD.

Claim 2

A SYSTEM FOR SUPPLYING CONSTANT FREQUENCY POLYPHASE POWER TO PLURAL PHASE POWER LOAD FROM A POLYPHASE A.C. POWER SOURCE OF VARIABLE FREQUENCY INCLUDING A GROUP OF SWITCH DEVICES IN EACH OF THE POWER PHASES LINES FOR DIRECTLY CONNECTING THE POWER PHASES TO THE LOAD PHASES, EACH OF SAID GROUPS CONTAINING A NUMBER OF SWITCHES EACH DIRECTLY CONNECTED TO A DIFFERENT ONE OF THE LOAD PHASES, A PULSE SOURCE POWERED BY SAID POWER SOURCE FOR OPERATING SAID SWITCHES HAVING A PLURALITY OF OUTPUTS AND PRODUCING AT EACH OUTPUT A TRAIN OF PLUSES HAVING A RECURRENCE FREQUENCY WHICH DIFFERS FROM THE POWER SOURCE FREQUENCY BY AN AMOUNT EQUAL TO THE DESIRED CONSTANT FREQUENCY, EACH OF SAID PULSE OUTPUTS BEING CONNECTED TO ONE SWITCH IN EACH OF SAID GROUPS TO CLOSE THE SWITCH IN RESPONSE TO A PULSE AND ALLOW THAT PORTION OF THE WAVEFORM THEN OCCURING TO FLOW TO A LOAD PHASE FOR THE DURATION OF THE PULSE THE SWITCHES CONNECTED TO THE SAME LOAD PHASE BEING CONNECTED TO DIFFERENT PULSE OUTPUTS, THE PULSES AT THE DIFFRENT PULSE OUTPUTS BEING DISPLACED IN PHASE BY AN AMOUNT SUCH THAT THE SWITCHES CONNECTED TO THE SAME LOAD PHASE ARE OPERATED TO SEQUENTIALLY CONNECT EACH POWER PHASE TO THE LOAD PHASE TO PRODUCE AT EACH LOAD PHASE A SERIES OF WAVEFORM PORTIONS HAVING AS A COMPONENT THEREOF THE DESIRED CONSTANT FREQUENCY, AND FREQUENCY DISCRIMINATING MEANS CONNECTED BETWEEN ONE OF THE LOAD PHASES AND THE PULSE SOURCE TO VARY THE PULSE RECURRENCE FREQUENCY TO MAINTAIN THE DESIRED CONSTANT FREQUENCY AT THE LOAD.
