Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
140 words
A PHASE SHIFTING DEVICE COMPRISING: ELECTRON BEAM PRODUCING MEANS, TRANSMISSION MEANS HAVING SAID ELECTRON BEAM PRODUCING MEANS MOUNTED UPON A PORTION THEREOF, SAID TRANSMISSION MEANS HAVING A PLURALITY OF ELONGATED SLOTS ORIENTED SO AS TO ALLOW SAID BEAM PRODUCING MEANS TO PROJECT A BEAM OF ELECTRONS THROUGH SAID SLOTS AND ACROSS SAID TRANSMISSION MEANS, MICROWAVE SIGNAL MEANS PROVIDING A SIGNAL INTO SAID TRANSMISSION MEANS, AND MEANS TO VARY THE PATH LENGTH OF ENERGY TRAVELING WITHIN SAID TRANSMISSION MEANS INCLUDING ELECTRON BEAM DEFLECTION MEANS OPERATIVE TO MOVE SAID ELECTRON BEAM ALONG THE LENGTH OF SAID SLOTS IN A DIRECTION PARALLEL TO THE PATH OF SAID ENERGY SO THAT SAID ENERGY IMPINGES UPON SAID BEAM OF ELECTRONS AT VARIED POINTS ALONG SAID TRANSMISSION MEANS THEREBY SHIFTING THE PHASE OF SAID ENERGY WHILE MAINTAINING THE FREQUENCY OF SAID ENERGY AT A CONSTANT VALUE.
Claim 2
Dependent Claim
140 words
A PHASE SHIFTING DEVICE COMPRISING: ELECTRON BEAM PRODUCING MEANS, TRANSMISSION MEANS HAVING SAID ELECTRON BEAM PRODUCING MEANS MOUNTED UPON A PORTION THEREOF, SAID TRANSMISSION MEANS HAVING A PLURALITY OF ELONGATED SLOTS ORIENTED SO AS TO ALLOW SAID BEAM PRODUCING MEANS TO PROJECT A BEAM OF ELECTRONS THROUGH SAID SLOTS AND ACROSS SAID TRANSMISSION MEANS, MICROWAVE SIGNAL MEANS PROVIDING A SIGNAL INTO SAID TRANSMISSION MEANS, AND MEANS TO VARY THE PATH LENGTH OF ENERGY TRAVELING WITHIN SAID TRANSMISSION MEANS INCLUDING ELECTRON BEAM DEFLECTION MEANS OPERATIVE TO MOVE SAID ELECTRON BEAM ALONG THE LENGTH OF SAID SLOTS IN A DIRECTION PARALLEL TO THE PATH OF SAID ENERGY SO THAT SAID ENERGY IMPINGES UPON SAID BEAM OF ELECTRONS AT VARIED POINTS ALONG SAID TRANSMISSION MEANS THEREBY SHIFTING THE PHASE OF SAID ENERGY WHILE MAINTAINING THE FREQUENCY OF SAID ENERGY AT A CONSTANT VALUE.
Claim 3
Dependent Claim
33 words
A MICROWAVE SYSTEM INCLUDING AT LEAST ONE PHASE SHIFTING DEVICE COMPRISING: ELECTRON BEAM PRODUCING MEANS, TRANSMISSION MEANS HAVING SAID ELECTRON BEAM PRODUCING MEANS MOUNTED UPON A PORTION THEREOF TO PROVIDE A BEAM UNIT,
Claim 4
Dependent Claim
33 words
A MICROWAVE SYSTEM INCLUDING AT LEAST ONE PHASE SHIFTING DEVICE COMPRISING: ELECTRON BEAM PRODUCING MEANS, TRANSMISSION MEANS HAVING SAID ELECTRON BEAM PRODUCING MEANS MOUNTED UPON A PORTION THEREOF TO PROVIDE A BEAM UNIT,
Claim 5
Dependent Claim
68 words
THE SYSTEM OF CLAIM 3 FURTHER INCLUDING: A PLURALITY OF SAID PHASE SHIFTING DEVICES, A PLURALITY OF SCANNING ANTENNAS EACH COUPLED TO A SEPARATE ONE OF SAID PHASE SHIFTING DEVICES TO PROVIDE PHASE DIFFERENCES TO RADIATION EMANATING FROM SAID SCANNING ANTENNAS BY INTRODUCING SAID BEAM OF ELECTRONS INTO EACH OF SAID PHASE SHIFTING DEVICES AT DIFFERENT POSITIONS RELATIVE TO THEIR RESPECTIVE SLOTS AT THE SAME INSTANT OF TIME.
