Abstract
Abstract The invention relates to a tube assembly for use in isotopic separation diffusers. Each tube assembly is secured at each end to an end-plate and comprises a number of filter tubes assembled by fitting together adjacent ends which are provided with inter-fitting spigots having a diameter greater than that of the body of the tube. The assembled tubes are connected together in bundles by means of resilient means located at the level of the spigots so that the tubes make contact with each other via the abutting spigots.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
95 words
An assembly of tubes for isotopic separation diffusers comprising candles made up of filter tubes and secured at each end to a bottom plate and a top plate, the filter tubes of each candle being assembled by fitting together and brazing the skirts at the end of their spigots, the candles being assembled in one bundle by resilient tightening means at at least the level of the spigots, which are slightly larger in diameter than the filter tube bodies, so that the candles in a single bundle make contact via the skirts of the spigots.
Claim 2
Dependent Claim
95 words
An assembly of tubes for isotopic separation diffusers comprising candles made up of filter tubes and secured at each end to a bottom plate and a top plate, the filter tubes of each candle being assembled by fitting together and brazing the skirts at the end of their spigots, the candles being assembled in one bundle by resilient tightening means at at least the level of the spigots, which are slightly larger in diameter than the filter tube bodies, so that the candles in a single bundle make contact via the skirts of the spigots.
Claim 3
Dependent Claim
16 words
A tube assembly according to claim 1, wherein the candles are distributed around a central mast.
Claim 4
Dependent Claim
18 words
A tube assembly according to claim 2, wherein the central mast is tubular and secured to the end-plates.
Claim 5
Dependent Claim
22 words
A tube assembly according to claim 2, wherein the central mast is tubular and slides with respect to one of the end-plates.
Claim 6
Dependent Claim
19 words
A tube assembly according to claim 1 the means for resiliently tightening the candles are metal strips or hoops.
Claim 7
Dependent Claim
26 words
A tube assembly according to claim 2, wherein the central mast is a lattice construction having a polygonal section enabling gases to flow at low pressure.
Claim 8
Dependent Claim
51 words
A tube assembly according to claim 1 layers of polygonal structures in the form of a star having a number of arms and threaded on the central lattice mast, and also comprises sectional hoops, rings or collars resiliently connected between the arms of each structure in order to tighten the bundles.
Claim 9
Dependent Claim
80 words
A tube assembly according to claim 1, comprising layers of polygonal structures in the form of a star having a number of arms, sectional hoops, rings or collars resiliently connected between the arms of each structure so as to tighten the bundles, and resilient cambered strips secured in the longitudinal direction of the bundles between the hoops or collars of the successive layers of structures, a cambered part of the strips bearing on the inner wall of the diffuser casing.
Claim 10
Dependent Claim
72 words
A tube assembly according to claim 1, wherein the candles are disposed side by side over the entire surface of the end-plates, layers of sectional hoops or collars resiliently connected to one another surround the candles, and resilient cambered strips are secured in the longitudinal direction of the candles between the hoops or collars of each layer, a cambered part of the strips bearing on the inner wall of the diffuser casing.
