Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 191 words
A pre-TR high power/intermediate power stage apparatus for receiver protectors comprising in combination: a quartz cylinder having a longitudinal groove in its inner surface, said quartz cylinder being sealed at both ends, said quartz cylinder containing a halogen gas at a predetermined pressure, said quartz cylinder having a predetermined diameter, and a means for mounting said quartz cylinder, said mounting means substantially surrounding said quartz cylinder, said mounting means having a first and second slot, therein, positioned diametrically opposite each other on said quartz cylinder, said first slot being larger than said second slot, said second slot being adjacent to said longitudinal groove in said quartz cylinder, said first and second slot being parallel to each other and to the longitudinal axis of said quartz cylinder, said first and second slot being in a same plane with said longitudinal groove in said quartz cylinder, said mounting means being connected to and in front of a receiver waveguide protector means, said mounting means having the same outside dimension as said receiver waveguide protector means, said quartz cylinder having its outside diameter equal in size to the inside dimension of said mounting means.
Claim 2
Dependent Claim 191 words
A pre-TR high power/intermediate power stage apparatus for receiver protectors comprising in combination: a quartz cylinder having a longitudinal groove in its inner surface, said quartz cylinder being sealed at both ends, said quartz cylinder containing a halogen gas at a predetermined pressure, said quartz cylinder having a predetermined diameter, and a means for mounting said quartz cylinder, said mounting means substantially surrounding said quartz cylinder, said mounting means having a first and second slot, therein, positioned diametrically opposite each other on said quartz cylinder, said first slot being larger than said second slot, said second slot being adjacent to said longitudinal groove in said quartz cylinder, said first and second slot being parallel to each other and to the longitudinal axis of said quartz cylinder, said first and second slot being in a same plane with said longitudinal groove in said quartz cylinder, said mounting means being connected to and in front of a receiver waveguide protector means, said mounting means having the same outside dimension as said receiver waveguide protector means, said quartz cylinder having its outside diameter equal in size to the inside dimension of said mounting means.
Claim 3
Dependent Claim 22 words
