Abstract
Abstract In order to suppress vibrations at a point of a bundle of parallel tubes without complicating the assembly of the bundle or entailing the need to dismantle the tube bundle after it has been installed, there is accordingly inserted between the tubes of the bundle a first series of parallel plates which are carried by an end-plate and which limit vibrations in a first direction, then a second series of parallel plates perpendicular to the first one for limiting the vibrations in a second direction, the two series of plates are then displaced by sliding in a longitudinal direction and thereby interassembled in such a manner that each tube is placed in a parallelepipedal recess while being in contact only with one or at a maximum with two of said plates, whereupon the two series of plates are rigidly fastened together.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
179 words
A method of assembling a device for the suppression of vibrations in a bundle of fixed parallel tubes which consists in sliding between adjacent tubes at right angles to the axes of the tubes a first series of parallel members for limiting vibrations in a predetermined direction, sliding between adjacent tubes of the bundle at right angles to the axes of the tubes and at right angles to and axially spaced from said first series of parallel members a second series of parallel members which are similar to the first series for limiting vibrations in a direction at right angles to said predetermined direction, and in interassembling the two series of members to form a series of parallelepipedal spaces with at least one of adjacent members of each of said series having a small clearance with the outer wall of the tube disposed therebetween so that a portion of each tube is in contact with at least one member of one of said series while being surrounded by portions of four members and subjected to only a limited stress.
Claim 2
Independent Claim
179 words
A method of assembling a device for the suppression of vibrations in a bundle of fixed parallel tubes which consists in sliding between adjacent tubes at right angles to the axes of the tubes a first series of parallel members for limiting vibrations in a predetermined direction, sliding between adjacent tubes of the bundle at right angles to the axes of the tubes and at right angles to and axially spaced from said first series of parallel members a second series of parallel members which are similar to the first series for limiting vibrations in a direction at right angles to said predetermined direction, and in interassembling the two series of members to form a series of parallelepipedal spaces with at least one of adjacent members of each of said series having a small clearance with the outer wall of the tube disposed therebetween so that a portion of each tube is in contact with at least one member of one of said series while being surrounded by portions of four members and subjected to only a limited stress.
Claim 3
Dependent Claim
28 words
A method in accordance with claim 1, wherein each tube is in contact with one member of each of said first and second series of members at maximum.
Claim 4
Dependent Claim
29 words
A method in accordance with claim 1, wherein both series of members are rigidly fixed to the stationary tube support after being interassembled within the bundle of fixed tubes.
