Gating system with variable delay

Claim 1

IN A GATING SYSTEM, IN COMBINATION, A TIME MODULATOR CIRCUIT HAVING AN ADJUSTABLE DELAY CIRCUIT MEANS, A GENERATOR FOR RECURRENT SYNCHRONIZING PULSES CONNECTED TO SAID TIME MODULATOR CIRCUIT FOR FEEDING SAID SYNCHRONIZING PULSES TO THE MODULATOR CIRCUIT, MEANS IN SAID TIME MODULATOR CIRCUIT GENERATING IN RESPONSE TO EACH SYNCHRONIZING PULSE AN ELECTRIC SIGNAL AFTER AN ADJUSTED DELAY, A GATING PULSE GENERATING SYSTEM, A CIRCUIT CONNECTION BETWEEN SAID SYSTEM AND SAID TIME MODULATOR, THE SIGNAL GENERATED BY THE TIME MODULATOR BEING APPLIED TO SAID CONNECTION, MEANS IN THE GATING PULSE GENERATING SYSTEM WHICH IN RESPONSE TO EACH SIGNAL APPLIED TO SAID CONNECTION GENERATE TWO SUCCESSIVE GATING PULSES OF FIXED DURATION, A FIRST AND A SECOND GATING CIRCUIT TO WHICH RECURRENT PULSES, RECEIVED FROM OUTSIDE THE SYSTEM, ARE APPLIED, A CIRCUIT CONNECTION FOR FEEDING THE FIRST OF TWO SUCCESSIVE GATING PULSES TO THE FIRST GATING CIRCUIT WHICH IN RESPONSE TO A COINCIDING FIRST GATING PULSE AND RECEIVED RECURRENT PULSE PERMITS PASSAGE OF AN OVERLAPPING PART OF THE LATTER PULSE TO THE OUTPUT CIRCUIT OF THE FIRST GATING CIRCUIT, A CIRCUIT CONNECTION FOR FEEDING THE SECOND OF TWO SUCCESSIVE GATING PULSES TO THE SECOND GATING CIRCUIT WHICH IN RESPONSE TO A COINCIDING SECOND GATING PULSE AND A RECEIVED RECURRENT PULSE PERMITS PASSAGE OF AN OVERLAPPING PART OF THE LATTER PULSE TO THE OUTPUT CIRCUIT OF THE SECOND GATING CIRCUIT, A CIRCUIT MEANS INTEGRATING WITH RESPECT TO TIME, CIRCUIT CONNECTIONS BETWEEN SAID CIRCUIT MEANS AND THE OUTPUT CIRCUITS OF THE TWO GATING CIRCUITS, MEANS IN SAID CIRCUIT CONNECTIONS FOR CAUSING THE OUTPUT VOLTAGE OF THE INTEGRATING CIRCUIT MEANS TO BE VARIED IN MAGNITUDE ACCORDING TO THE CHANGES IN THE DIFFERENCE OF THE ENERGY CONTENT BETWEEN THE PARTS OF THE PULSES PASSING THROUGH THE ONE OF THE TWO GATING CIRCUITS AND THE PARTS OF THE PULSES PASSING THROUGH THE OTHER OF THE TWO GATING CIRCUITS, A CIRCUIT CONNECTION BETWEEN THE INTEGRATING CIRCUIT MEANS AND THE TIME MODULATOR CIRCUIT FOR APPLYING AN OUTPUT VOLTAGE OF THE INTEGRATING CIRCUIT MEANS TO THE TIME MODULATOR CIRCUIT, MEANS IN SAID MODULATOR CIRCUIT FOR CHANGING THE DELAY IN THE TIME MODULATOR CIRCUIT IN ACCORDANCE WITH THE OUTPUT VOLTAGE OF THE INTEGRATING CIRCUIT MEANS, FIRST SWITCHING MEANS FOR RENDERING THE PART OF THE CIRCUIT COMPRISING THE GATING CIRCUITS AND THE INTEGRATING CIRCUIT MEANS INOPERATIVE TO CONTROL THE DELAY IN THE TIME MODULATOR CIRCUIT, MEANS FOR MANUALLY CONTROLLING THE SAID DELAY, A DISPLAY SYSTEM COMPRISING A CATHODE RAY TUBE INCLUDING BEAM DEFLECTING MEANS AND A TIME BASE GENERATOR SYNCHRONIZED BY THE SYNCHRONIZING PULSES AND CONTROLLING THE BEAM DEFLECTING MEANS TO PRODUCE A DEFLECTION FOR THE ELECTRON BEAM FOR CAUSING A TIME-BASE SCANNING MOTION OF THE CATHODE RAY UPON EACH RECEPTION OF A SYNCHRONIZING PULSE BY THE GATING SYSTEM, MEANS FOR CONTROLLING THE ELECTRON BEAM TO WHICH THE RECURRENT RECEIVED PULSES ARE ALSO APPLIED, AND WHICH IN RESPONSE TO SUCH PULSES CHANGE THE ELECTRON BEAM, MEANS FOR GENERATING PULSES SUBSTANTIALLY CORRESPONDING IN DURATION AND MOMENT OF OCCURRENCE TO THE SUM OF THE GATING PULSES, AND FOR APPLYING SAID PULSES TO THE MEANS FOR CONTROLLING THE ELECTRON BEAM, SAID BEAM CONTROLLING MEANS IN RESPONSE TO SAID PULSES CHANGING THE ELECTRON BEAM, AND SECOND SWITCHING MEANS OPERATING INDEPENDENTLY OF THE FIRST SWITCHING MEANS AND CAPABLE OF CHANGING THE DURATION OF THE SECOND GATING PULSE SO AS TO MAKE THE DURATION OF SAID PULSE SUBSTANTIALLY LONGER THAN THAT OF THE FIRST GATING PULSE.
