Abstract
Abstract A two-element waveguide terminator, wherein at the place where the flanged end of a waveguide is sandwiched between a flange of one terminator element and the other terminator element, there remains a hollow space between these elements. The one element is a sleeve disposed as a fitting over the waveguide end, but a hollow clearance space remains between sleeve and waveguide end. The one terminator element is provided with ducts interconnecting the two hollow spaces which are filled with a viscous elastic material, such as silicone rubber.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
158 words
Termination arrangement, including a waveguide, a first element and a second element connected to the end of the waveguide, the waveguide having a flanged end; the first element having a sleeve disposed as a fitting on the waveguide, the sleeve having one end provided with a radially extending flange, the first and second elements disposed to sandwich the flanged end of the waveguide in between the flange of the first element and the second element, there remaining a first hollow space between the flange of the first element and the second element, the two elements being secured to each other; the sleeve portion of the first element, as receiving the waveguide near the flanged end thereof, providing a second ring space between the sleeve and the waveguide; means defining a plurality of ducts in the first element, interconnecting the first and the second space; and an initially viscous, subsequently elastic material filling the first space and the ducts.
Claim 2
Dependent Claim
158 words
Termination arrangement, including a waveguide, a first element and a second element connected to the end of the waveguide, the waveguide having a flanged end; the first element having a sleeve disposed as a fitting on the waveguide, the sleeve having one end provided with a radially extending flange, the first and second elements disposed to sandwich the flanged end of the waveguide in between the flange of the first element and the second element, there remaining a first hollow space between the flange of the first element and the second element, the two elements being secured to each other; the sleeve portion of the first element, as receiving the waveguide near the flanged end thereof, providing a second ring space between the sleeve and the waveguide; means defining a plurality of ducts in the first element, interconnecting the first and the second space; and an initially viscous, subsequently elastic material filling the first space and the ducts.
Claim 3
Dependent Claim
33 words
Termination arrangement as in claim 1, there being a groove in the sleeve, facing the waveguide and disposed adjacent the end of sleeve which is remote from the flanged end of the sleeve.
Claim 4
Dependent Claim
36 words
Termination arrangement as in claim 1, the flange of the first element having an axially directed front end, the ducts terminating in the first end, there being a groove in the front end interconnecting the ducts.
Claim 5
Dependent Claim
20 words
Termination arrangement as in claim 1, the flange of the first element bearing against the flange of the waveguide end.
Claim 6
Dependent Claim
20 words
Termination arrangement as in claim 1, the first element provided with indexing grooves for orienting equipment for flanging the waveguide.
