Abstract
Abstract The invention concerns the centering and the fixing of a long thin object inside a tubular body. It has as its object a means consisting in a filling in of the space left free by the long thin object inside the tubular body with a granular substance at least a part of which is agglomerated by means of a resinous isocure compound hardening when cold in a very short time on coming into contact with a gaseous catalyst. It applies more particularly to the centering of a wave guide in a metallic tube.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
100 words
In combination, a tubular body having an axially extending internal wall, a long thin object axially disposed inside said tubular body, a filling material made of a granular substance extending between the long thin object and the internal wall of said tubular body, said filling material comprising an axial succession of agglomarated layers separated by non-agglomarated layers of granular substance, said agglomarated layers comprising filling material being agglomaratedly hardened in situ by a resinous compound hardened when cold, in a short time by contact with a gas borne catalyst such that the assembly formed thereby is free of thermal stress.
Claim 2
Dependent Claim
