Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
89 words
A MAGNETRON ANODE STRUCTURE COMPRISING AN ANNULAR BLOCK, A PLURALITY OF ANODE SEGMENTS EXTENDING RADIALLY INWARD FROM SAID ANNULAR BLOCK, ALTERNATE SEGMENTS BEING FABRICATED OF A MATERIAL HAVING A HIGH COEFFICIENT OF THERMAL EXPANSION, THE INTERVENING SEGMENTS BEING FABRICATED OF A MATERAIL HAVING A LOW COEFFICIENT OF THERMAL EXPANSION, A FIRST CONDUCTIOVE RING ADJACENT TO THE INNER EDGES OF SAID SEGMENTS CONNECTED TO SAID ALTERNATE SEGMENTS, AND A SECOND CONDUCTIVE RING OF LARGER DIAMETER THAN THE FIRST RING ADJACENT TO SAID FIRST RING AND CONNECTED TO THE INTERVENING SEGMENTS.
