Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
70 words
IN A ROTATING RECTIFIER EXCITER, A RECTIFIER WHEEL RIM SUPPORTING A PLURALITY OF CYLINDRICALLY SHAPED HEAT SINKS ON THE INTERIOR SURFACE THEREOF AND ELECTRICALLY INSULATED THEREFROM, EACH OF SAID HEAT SINKS SUPPORTING AT LEAST ONE SEMICONDUCTING DIODE IN THE CENTER PORTION THEREOF, EACH OF SAID HEAT SINKS BEING SECURED TO SAID RIM BY A THREADED EXTENSION OF THE HEAT SINK BODY THREADED INTO AN INSULATING INSERT LOCATED IN SAID RIM.
Claim 2
Dependent Claim
70 words
IN A ROTATING RECTIFIER EXCITER, A RECTIFIER WHEEL RIM SUPPORTING A PLURALITY OF CYLINDRICALLY SHAPED HEAT SINKS ON THE INTERIOR SURFACE THEREOF AND ELECTRICALLY INSULATED THEREFROM, EACH OF SAID HEAT SINKS SUPPORTING AT LEAST ONE SEMICONDUCTING DIODE IN THE CENTER PORTION THEREOF, EACH OF SAID HEAT SINKS BEING SECURED TO SAID RIM BY A THREADED EXTENSION OF THE HEAT SINK BODY THREADED INTO AN INSULATING INSERT LOCATED IN SAID RIM.
Claim 3
Dependent Claim
110 words
IN COMBINTAION, AN ANNULAR FLANGE HAVING A SPIDER FRAME AND HUB PORTION MOUNTED ON A ROTATING SHAFT, A PLURALITY OF HEAT SINKS HAVING A THREADED PORTION THREADED INTO BUT INSULATED FROM THE INTERIOR SURFACE OF SAID FLANGE AND EXTENDING RADIALLY BETWEEN SAID FLANGE AND HUB PORTION, A SEMICONDUCTING DIODE DEVICE RADIALLY MOUNTED ON EACH OF SAID HEAT SINKS INTERMEDIATE SAID FLANGE AND HUB PORTION, A PAIR OF CONDUCTIVE CONNECTORS FOR EACH DIODE DEVICE CIRCUMFERENTIALLY DISTRIBUTED WITHIN SAID FRAME, ONE OF SIAD CONNECTORS HAVING ONE END CONNECTED TO A TERMINAL ON SAID DIODE, THE OTHER OF SAID CONNECTORS HAVING AN END SECURED TO THE HEAT SINK AND IN ELECTRICAL CONTACT THEREWITH.
Claim 4
Dependent Claim
110 words
IN COMBINTAION, AN ANNULAR FLANGE HAVING A SPIDER FRAME AND HUB PORTION MOUNTED ON A ROTATING SHAFT, A PLURALITY OF HEAT SINKS HAVING A THREADED PORTION THREADED INTO BUT INSULATED FROM THE INTERIOR SURFACE OF SAID FLANGE AND EXTENDING RADIALLY BETWEEN SAID FLANGE AND HUB PORTION, A SEMICONDUCTING DIODE DEVICE RADIALLY MOUNTED ON EACH OF SAID HEAT SINKS INTERMEDIATE SAID FLANGE AND HUB PORTION, A PAIR OF CONDUCTIVE CONNECTORS FOR EACH DIODE DEVICE CIRCUMFERENTIALLY DISTRIBUTED WITHIN SAID FRAME, ONE OF SIAD CONNECTORS HAVING ONE END CONNECTED TO A TERMINAL ON SAID DIODE, THE OTHER OF SAID CONNECTORS HAVING AN END SECURED TO THE HEAT SINK AND IN ELECTRICAL CONTACT THEREWITH.
