Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
116 words
A METHOD OF OPERATING A ROLLING MILL WHEREIN STRIP GAGE REGULATING MECHANISM IS CONTROLLED AT LEAST PARTIALLY BY A GAGE SIGNAL FROM A SUCCEEDING RADIATION TYPE GAGE WHICH MEASURES THE GAGE OF THE STRIP IN THE MILL COMPRISING: (A) CONTROLLING THE ADJUSTMENT OF SAID STRIP GAGE REGULATING MECHANISM AT LEAST PARTIALLY FROM A STRIP GAGE INDICATING RADIATION TYPE SIGNAL, (B) INTERRUPTING SAID STRIP GAGE INDICATING RADIATION SIGNAL, AND (C) SUBSTITUTING THEREFOR DURING SAID INTERRUPTION A LOAD CELL SIGNAL FROM A ROLLING MILL STAND OF SAID ROLLING MILL SUCCEEDING SAID STRIP GAGE REGULATING MECHANISM TO CONTROL SAID MECHANISM TO REGULATE THE GAGE OF THE STRIP DURING SAID INTERRUPTION WHILE THE RADIATION SIGNAL IS UNAVAILABLE FOR CONTROL PURPOSES.
Claim 2
Independent Claim
116 words
A METHOD OF OPERATING A ROLLING MILL WHEREIN STRIP GAGE REGULATING MECHANISM IS CONTROLLED AT LEAST PARTIALLY BY A GAGE SIGNAL FROM A SUCCEEDING RADIATION TYPE GAGE WHICH MEASURES THE GAGE OF THE STRIP IN THE MILL COMPRISING: (A) CONTROLLING THE ADJUSTMENT OF SAID STRIP GAGE REGULATING MECHANISM AT LEAST PARTIALLY FROM A STRIP GAGE INDICATING RADIATION TYPE SIGNAL, (B) INTERRUPTING SAID STRIP GAGE INDICATING RADIATION SIGNAL, AND (C) SUBSTITUTING THEREFOR DURING SAID INTERRUPTION A LOAD CELL SIGNAL FROM A ROLLING MILL STAND OF SAID ROLLING MILL SUCCEEDING SAID STRIP GAGE REGULATING MECHANISM TO CONTROL SAID MECHANISM TO REGULATE THE GAGE OF THE STRIP DURING SAID INTERRUPTION WHILE THE RADIATION SIGNAL IS UNAVAILABLE FOR CONTROL PURPOSES.
Claim 3
Dependent Claim
130 words
A CONTROL SYSTEM FOR CONTINUOUS REGULATION OF STRIP GAGE IN A ROLLING MILL COMPRISING: (A) A CONTROL CIRCUIT TO CONTROL THE OPERATION OF A STRIP GAGE REGULATING MECHANISM ON THE MILL IN RESPONSE TO AN EXTERNALLY RECEIVED GAGE CONTROL SIGNAL INDICATIVE TO THE AGREE OF THE STRIP PASSING SAID REGULATING MECHANISM, (B) A TRAVERSING RADIATION GAGE TO PROVIDE A STRIP GAGE INDICATING CONTROL SIGNAL TO SAID CONTROL CIRCUIT, (C) A LOAD CELL LOCATED ON A MILL STAND SUCCEEDING SAID GAGE REGULATING MECHANISM TO PROVIDE A STRIP GAGE INDICATING CONTROL SIGNAL TO THE CONTROL CIRCUIT, AND (D) SWITCHING CONTROL MEANS OPERATIVE TO REMOVE THE RADIATION GAGE SIGNAL FROM THE CONTROL CIRCUIT WHEN THE RADIATION GAGE TRANSVERSES FROM THE CENTRAL PORTION OF THE STRIP AND SUBSTITUTE THEREFOR THE SAID LOAD CELL SIGNAL.
Claim 4
Dependent Claim
130 words
A CONTROL SYSTEM FOR CONTINUOUS REGULATION OF STRIP GAGE IN A ROLLING MILL COMPRISING: (A) A CONTROL CIRCUIT TO CONTROL THE OPERATION OF A STRIP GAGE REGULATING MECHANISM ON THE MILL IN RESPONSE TO AN EXTERNALLY RECEIVED GAGE CONTROL SIGNAL INDICATIVE TO THE AGREE OF THE STRIP PASSING SAID REGULATING MECHANISM, (B) A TRAVERSING RADIATION GAGE TO PROVIDE A STRIP GAGE INDICATING CONTROL SIGNAL TO SAID CONTROL CIRCUIT, (C) A LOAD CELL LOCATED ON A MILL STAND SUCCEEDING SAID GAGE REGULATING MECHANISM TO PROVIDE A STRIP GAGE INDICATING CONTROL SIGNAL TO THE CONTROL CIRCUIT, AND (D) SWITCHING CONTROL MEANS OPERATIVE TO REMOVE THE RADIATION GAGE SIGNAL FROM THE CONTROL CIRCUIT WHEN THE RADIATION GAGE TRANSVERSES FROM THE CENTRAL PORTION OF THE STRIP AND SUBSTITUTE THEREFOR THE SAID LOAD CELL SIGNAL.
