Abstract
Abstract A waveguide assembly including a toroid of gyromagnetic material closely fitted within the waveguide includes first and second pieces of dielectric material dimensioned to substantially fill the void in the center of the toroid. A flexible tube having a normal diameter slightly greater than that of the spacing between the dielectric pieces is stretched, placed within the toroid between the pieces and then allowed to relax to lock the pieces in the center of the toroid.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
105 words
A waveguide assembly comprising: a waveguide, a toroid or gyromagnetic material positioned within the walls of said waveguide, said toroid having a centered aperture therein extending the length of the toroid, a plurality of dielectric bodies dimensioned and positioned within said centered aperture to substantially fill the centered aperture leaving a small gap of a given spacing near the center of the aperture between the bodies, a flexible tube having a normal diameter greater than said given spacing positioned within said small gap between the two dielectric bodies to hold the bodies within the aperture by the expansion of said tube toward its normal diameter.
Claim 2
Dependent Claim
105 words
A waveguide assembly comprising: a waveguide, a toroid or gyromagnetic material positioned within the walls of said waveguide, said toroid having a centered aperture therein extending the length of the toroid, a plurality of dielectric bodies dimensioned and positioned within said centered aperture to substantially fill the centered aperture leaving a small gap of a given spacing near the center of the aperture between the bodies, a flexible tube having a normal diameter greater than said given spacing positioned within said small gap between the two dielectric bodies to hold the bodies within the aperture by the expansion of said tube toward its normal diameter.
Claim 3
Dependent Claim
15 words
The combination claimed in claim 1 including a biasing wire passing through said small gap.
Claim 4
Dependent Claim
16 words
The combination claimed in claim 1 wherein said dielectric bodies are two substantially equally dimensioned bodies.
Claim 5
Independent Claim
120 words
The method of mounting dielectric bodies within a toroid positioned between waveguide walls and for providing an aperture through said toroid by which a biasing wire can be passed through said toroid comprising: providing a toroid of gyromagnetic material having a centered aperture, inserting a stretched thin walled tube of a normally larger diameter within the centered aperture of the toroid, inserting bodies of dielectric material within the center aperture of the toroid so that said bodies with the stretched tube substantially fill the void of the slot, relaxing said tube causing said tube to expand to said normal diameter thereof and push the dielectric bodies against toroid locking said bodies and said tube within the center of said toroid.
Claim 6
Independent Claim
120 words
The method of mounting dielectric bodies within a toroid positioned between waveguide walls and for providing an aperture through said toroid by which a biasing wire can be passed through said toroid comprising: providing a toroid of gyromagnetic material having a centered aperture, inserting a stretched thin walled tube of a normally larger diameter within the centered aperture of the toroid, inserting bodies of dielectric material within the center aperture of the toroid so that said bodies with the stretched tube substantially fill the void of the slot, relaxing said tube causing said tube to expand to said normal diameter thereof and push the dielectric bodies against toroid locking said bodies and said tube within the center of said toroid.
