Storage cathode ray tubes

Claim 1

A STORAGE CATHODE RAY TUBE FOR STORING ELECTRICAL SIGNALS COMPRISING AN ENVELOPE; A FORAMINOUS CHARGE STORONG TARGET STRUCTURE MOUNTED WITHIN SAID ENVELOPE AND INCLUDING A CONDUCTIVE GRID OR MESH HAVING DEPOSITED ON ONE SIDE THEREOF A LAYER OF INSULATING MATERIAL; ELECTRON GUN MEANS DISPOSED WITHIN SAID ENVELOPE FOR PRODUCING A PENCIL-LIKE ELECTRON BEAM, DEFLECTING MEANS FOR SCANNING SAID BEAM ACROSS SAID TARGET STRUCTURE; MEANS, CONTROLLED BY THE SIGNALS TO BE STORED, FOR CAUSING SAID BEAM TO PRODUCE A CHARGE PATTERN REPRESENTATIVE OF SAID SIGNALS ON SAID TARGET STRUCTURE DURING SIGNAL STORAGE; A FLUORESCENT SCREEN POSITIONED AT THE END OF SAID ENVELOPE REMOTE FROM SAID ELECTRON GUN MEANS; AND AT LEAST ONE COLLECTOR ELECTRODE PROVIDING ELECTRICAL SIGNALS OUTPUT FROM SAID TUBE DURING READOUT AND BEING POSITIONED AT THE GUN END OF SAID ENVELOPE TO RECEIVE AN AMOUNT OF BEAM ELECTRONS CONTROLLED BY THE GHARGES ON THE DIFFERENT PARTS OF SAID TARGET STRUCTURE, THE BEAM BEING DIVIDED INTO TWO PORTIONS AT SAID TARGET STRUCTURE IN ACCORDANCE WITH THE CHARGES THEREON, ONE PORTION PASSING THROUGH SAID TARGET STRUCTURE AND THE OTHER PORTION BEING REPELLED BY SAID TARGET STRUCTURE; SAID FLUORESCENT SCREEN BEING POSITIONED TO RECEIVE SAID ONE PORTION AND PROVIDING A VISUAL OUTPUT FROM SAID TUBE; AND SAID COLLECTOR ELECTRODE BEING POSITIONED TO RECEIVE SAID OTHER PORTION AND PROVIDING SAID ELECTRICAL SIGNAL OUTPUT.
