Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
104 words
An improved proportional counter including a gas filled cathode housing with a coaxially disposed anode and an insulator substrate at each end of said housing, the improvement comprising; a resistor conductor network of resistive material deposited upon said substrate at each end of said counter on the inner surface of each of said substrates with the ends of said resistive material secured electrically to the cathode and anode, where the resistor-conductor network obeys the formula ##EQU3## where b is the inner radius of the counter body, r is the radial distance from the center of the anode, and θ is the angle in radians.
Claim 2
Dependent Claim
104 words

Claim 3
Dependent Claim
32 words
An improved proportional counter as claimed in claim 1; in which, said resistor material is in the form of a spiral with the resistor ends connected between said anode and said cathode.
Claim 4
Dependent Claim
29 words
