Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
105 words
A waveguide assembly comprising: a waveguide of flexible conductive material and having a pair of opposite walls, a body of dielectric material spaced between the opposed walls of the waveguide, an external clamp coupled to the outside of the waveguide near one end of the body and the waveguide so as to force the opposed walls of the waveguide against a portion of the body and hold the body, and dielectric means coupled between the waveguide walls and a point along said body remote from the clamping portion for preventing transverse movement of said body within said waveguide but permitting longitudinal movement of said body.
Claim 2
Dependent Claim
105 words
A waveguide assembly comprising: a waveguide of flexible conductive material and having a pair of opposite walls, a body of dielectric material spaced between the opposed walls of the waveguide, an external clamp coupled to the outside of the waveguide near one end of the body and the waveguide so as to force the opposed walls of the waveguide against a portion of the body and hold the body, and dielectric means coupled between the waveguide walls and a point along said body remote from the clamping portion for preventing transverse movement of said body within said waveguide but permitting longitudinal movement of said body.
Claim 3
Dependent Claim
55 words
The combination claimed in claim 1 wherein said dielectric means includes a pair of dielectric spacers wherein one of said spacers is located in the region between a third wall of said waveguide and said body and the second spacer is located in the region between a fourth wall of said waveguide and said body.
Claim 4
Dependent Claim
26 words
The combination claimed in claim 2 wherein said spacer is U-shaped with the free ends against the body and the middle portion against the waveguide wall.
Claim 5
Dependent Claim
18 words
The combination claimed in claim 3 wherein said spacers include means for locking said spacers within said waveguide.
Claim 6
Dependent Claim
23 words
The combination claimed in claim 1 wherein said dielectric body includes a portion of gyromagnetic material and a portion of non-magnetic dielectric material.
Claim 7
Dependent Claim
12 words
The combination claimed in claim 5 wherein said gyromagnetic material is garnet.
Claim 8
Dependent Claim
22 words
The combination claimed in claim 6 wherein only said non-magnetic dielectric material portion of said body is clamped between said waveguide walls.
Claim 9
Dependent Claim
51 words
The combination claimed in claim 1 wherein said waveguide is rectangular and is made of thin walled aluminum tubing, said third and fourth walls being the opposite narrow walls of said waveguide, said clamp arranged to force the opposite broad walls of said waveguide against said body to hold said body.
