Cathode ray tube for processing digital data

Claim 1

A CATHODE RAY TUBE FOR PROCESSING DIGITAL DATA COMPRISING AN ELECTRON GUN INCLUDING A CATHODE, A PAIR OF PLATES POSITIONED AT AN ACUTE ANGLE WITH THE PLANE OF THE CATHODE FOR FORMING A SHEET BEAM, SAID PLATES BEING SPACED FROM SAID CATHODE, MEANS FOR SAID PLATES BEING ARRANGED FOR PROVIDING ON-OFF CONTROL OF THE EMISSION FROM SAID CATHODE, MEANS FOR ACCELERATING THE ELECTRON BEAM, AN ELECTRON LENS SYSTEM FOR DEVELOPING A POTENTIAL FIELD FOR FOCUSING THE ELECTRON BEAM ONTO THE FACE OF THE TUBE, SAID LENS SYSTEM COMPRISING AT LEAST THREE APERTURED LENSES POSITIONED TRANSVERSELY TO THE ELECTRON BEAM, FIRST APERTURED STOP MEANS POSITIONED INTERMEDIATE THE FIRST AND SECOND OF SAID LENS, SECOND APERTURED STOP MEANS POSITIONED INTERMEDIATE THE SECOND AND THIRD OF SAID LENS, SAID STOP MEANS BEING POSITIONED SO AS NOT TO DISTURB THE FOCUSING FIELD DEVELOPED BY SAID LENS, A PLURALITY OF ELECTRON BEAM DEFLECTING PLATES FOR CONTROLLING SAID BEAM TO IMPINGE AT SELECTED POINTS ON THE FACE OF THE TUBE, SAID PLURALITY OF PLATES BEING POSITIONED IN SPACED RELATION IN A TRUNCATED-CONE-LIKE ARRANGEMENT WITH A ROW OF TWO DEFLECTING PLATES FORMING THE NARROW END OF THE CONE AND BEING POSITIONED ADJACENT THE LENS SYSTEM, A ROW CONTAINING THE LARGEST NUMBER OF DEFLECTING PLATES POSITIONED ADJACENT THE FACE OF THE TUBE, SAID DEFLECTING PLATES PROVIDING A TRANSFER TREE TYPE OF DEFLECTION IN WHICH THE ELECTRON BEAM IS ROUTED TO ANY ONE OF A PLURALITY OF POINTS ON THE FACE OF THE TUBE ACCORDING TO THE COMBINATION OF POTENTIALS APPLIED TO SAID PLATES, AND A PLURALITY OF ANODE TABS ON THE FACE OF THE TUBE EACH ARRANGED TO PROVIDE AN OUTPUT WHEN THE ELECTRON BEAM IMPINGES THEREON.
