X-ray apparatus having means for supplying an alternating square wave voltage to the x-ray tube

Claim 1

X-RAY APPARATUS INCLUDING THE COMBINATION OF RECTIFIER MEANS ARRANGED TO BE ENERGIZED FROM AN A.C. POWER SOURCE AT A FIRST FREQUENCY TO FORM D.C. POWER SUPPLY MEANS, TRANSFORMER MEANS HAVING A PRIMARY WINDING WITH A CENTER TAP BETWEEN ITS ENDS AND A SECONDARY WINDING COUPLED TO THE PRIMARY WINDING, SWITCHING MEANS HAVING A FIRST SOLID STATE CONTROLLED RECTIFIER CONNECTED BETWEEN ONE END OF SAID PRIMARY WINDING AND GROUND, AND HAVING A SECOND SOLID STATE CONTOLLED RECTIFIER CONNECTED BETWEEN THE OTHER END OF SAID PRIMARY WINDING AND GROUND TO ALTERNATELY PRESS THE D.C. OUTPUT OF SAID POWER SUPPLY MEANS THROUGH SAID PRIMARY WINDING IN OPPOSITE DIRECTIONS TO PRODUCE AN A.C. OUTPUT AT A SECOND FREQUENCY IN THE SECONDARY WINDING, TRIGGERING CIRCUIT MEANS HAVING MULTIVIBRATOR MEANS ARRANGED TO PRODUCE A SQUARE WAVE OUTPUT, PHASE SPLITTER MEANS ACTIVATED BY SAID SQUARE WAVE OUTPUT TO PRODUCE FIRST AND SECOND OUT-TO-PHASE TRIGGERING
