Dynamic convergence assembly shielding and mounting structure

Claim 1

AN ELECTRON GUN MOUNT FOR A MULTIBEAM CATHODERAY TUBE COMPRISING: A PLURALITY OF ELECTRON GUNS ARRANGED IN A PREDETERMINED ARRAY, INDIVIDUALLY INCLUDING A CATHODE SUBASSEMBLY AND A SERIES OF CONDUCTIVE ELECTRODES ALIGNED ALONG A BEAM PATH FOR COLLECTIVELY DEVELOPING, ACCLELERATING AND FOCUSING A BEAM OF ELECTRONS ALONG SAID PATH, THE FINAL ELECTRODE OF EACH SERIES BEING A CYLINDER DISPOSED COAXIALLY OF SAID BEAM PATH AND HAVING A PAIR OF LONGITUDINALLY EXTENDING SIDE-BYSIDE SLOTS; A PLURALITY OF BEADING ELEMENTS SECURED TO ELECTRODES OF SAID GUNS TO INTEGRATE SAID GUNS INTO A GUN CLUSTER; SHIELDING MEANS FOR MAGNETICALLY SHIELDING THE SLOTTED ELECTRODES OF SAID GUNS FROM ONE ANOTHER COMPRISING A PLURALITY OF STRAPS OF FERROMAGNETIC MATERIAL INDIVIDUALLY HAVING AN END PORTIONS SECURED TO SAID BEADING ELEMENTS, AN INTERMEDIATE SECTION ENVELOPING AND SECURED TO THE OUTER PERIPHERY OF SAID SLOTTED ELECTRODE OF AN ASSIGNED ONE OF SAID GUNS ON THE PORTION THEREOF THAT FACES THE CENTER OF SAID GUN CLUSTER AND IS DIAMETRICALLY OPPOSED TO SAID SLOTS AND FURTHER HAVING A WIDTH DIMENSION EXCEEDING THE LONGITUDINAL DIMENSION OF SAID SLOTS; A PLURALITY OF PAIRS OF CONVERGENCE MAGNET POLE PIECES OF FERROMAGNETIC MATERIAL, INDIVIDUALLY THREADED THROUGH THE SLOTS OF THE SLOTTED ELECTRODE OF AN ASSIGNED ONE OF SAID GUNS AND COMPRISING POLE TIPS DISPOSED WITHIN ITS ASSIGNED ELECTRODE ON OPPOSITE SIDES OF THE BEAM PATH EXTENDING THROUGH ITS ASSIGNED ELECTRODE EACH OF SAID POLE PIECES FURTHER COMPRISING A SUPPORTING TAB CONCENTRIC WITH AND WELDED TO ITS RESPECTIVE CYLINDER AND A COUPLING PORTION NEARER THE NECK OF SAID TUBE THAN SAID TAB, DISPOSED PARALLEL TO SAID NECK FOR COUPLING TO AN EXTERNAL MAGNETIC SOURCE AND HAVING A LENGTH EXCEEDING THAT OF SAID SLOTS.
