Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
79 words
A METHOD OF EXTENDING AT LEAST ONE DIMENSION OF THE EFFECTIVE CROSS SECTION OF A COLLIMATED BEAM OF CHARGED PARTICLES, WHICH COMPRISES THE STEPS OF: BENDING THE BEAM THROUGH A PRESCRIBED ANGLE OF SUBSTANTIAL MAGNITUDE RELATIVE TO THE INITIAL PATH OF THE BEAM BY ARRANGING A MAGNETIC FIELD IN SAID PATH; AND MOVING THE MAGNETIC FIELD ALONG THE INITIAL PATH OF THE BEAM LONGITUDINALLY THEREOF TO CAUSE THE BENT PORTION OF THE BEAM TO SWEEP OVER AN ELONGATED AREA.
Claim 2
Independent Claim

Claim 3
Dependent Claim
98 words
APPARATUS FOR DEFLECTING CHARGED PARTICLES IN A COLLIMATED BEAM INTO AN ORBITAL PATH ABOUT AN OBJECT AND FOR DEFLECTING THE ORBITING PARTICLES INTO THE PORTIONS OF THE OBJECT WHICH THE ORBITAL PATH OVERLIES, WHICH COMPRISES: FIRST MAGNETIC MEANS ROTATABLE ABOUT ITS POLAR AXIS FOR PRODUCING A FIXED, CONTINUOUS AND UNIFORM MAGNETIC FIELD ABOUT THE OBJECT; MEANS FOR PRODUCING A COLLIMATED BEAM OF CHARGED PARTICLES DIRECTED INTO THE FIRST MAGNETIC FIELD TRANSVERSELY THEREOF AND OUTWARDLY OF THE PERIPHERY OF THE OBJECT, THE STRENGTH AND POLARITY OF THE FIRST MAGNETIC FIELD BEING SELECTED TO EXERT A FORCE ON THE CHARGED
