AbstractAbstract
[en] Fabrication of reinforced leaktight bellows, for use in a manipulator, comprising a conventional leaktight wall and a reinforcement for limiting the spreading of a crack in the wall and completely removing the risk of the bellows separating into two distinct parts. The wall can be made of an elastomer fabric covered with a reinforcement of flexible resistant threads with a stretch weave taking the shape of the wall

AbstractAbstract
[en] A valve with a bellow-sealed rod is described. The bello is placed in a closed volume filled with oil. To compensate changes in the bellow volume due to motion of the rod, the compensating bellow is placed in this volume, the inner space of the compensating bellow is connected to the gas main. Under the gas pressure the bellows are unloaded, and the working pressure for the valve is limited by the strength of the body

AbstractAbstract
[en] A pressure compactor has been assembled for spin-polarized liquid and solid 3He experiments. In place of a Kapton diaphragm, a beryllium-copper spring-bellows combination was used to attain a large volume change of 3He. The spring was specially designed and tested to ensure that its displacement at low temperature was a reversible process. (5 refs., 4 figs.)

AbstractAbstract
[en] This report presents relations describing the meridional and circumferential elastic stress levels at the root and crown due to external pressure and axial deflection of U-shaped bellows. The derivation is based on a statistical analysis of theoretical data obtained from a finite element analysis of selected bellows configurations. The mathematical formulations and various graphical representations are proposed as aids to bellows design and analysis. (auth)

AbstractAbstract
[en] In piping system, U-shaped Bellows are widely used among flexible elements. In general, bellows are typically design for Fatigue behavior according to the EJMA standard based on empirically generated fatigue curves. The present work proposes a methodology in the design of bellows by design by analyses and validates its design by EJMA standard. A linear FE approach is chosen to in line with the EJMA standard. The proposed methodology is benchmarked with the available literatures. The same practice is implemented in the preliminary design of a U-shaped bellows in the water line circuits of DNB beam source. DNB Beam Source is a negative ion source-based neutral beam generator for ITER operates at 100KV. The beam divergence (intrinsic) and magnetic fields from ITER torus causes deflection of beams. This calls for beam optic alignment, which are assured by BS Movement mechanism system. To accomplish the above movement requirements, bellows, which is a stringent of its kind (± 22 mm axial, ± 45 mm lateral within 400mm available space with single ply), is designed between the beam source and possible rigid interface-cooling lines coming from HVB. The paper describes right from conceptual stage to preliminary design. Optimization tools are adopted in the selecting bellow dimensions using MATLAB. At the end a coordinated approach between FE based assessment (in ANSYS) and widely applied code, EJMA is implemented for the validation of design and found FE approach is a very conservative than later in the present case.

AbstractAbstract
[en] The cylindrical container consists of austenitic steel and is welded vacuum-tight. The internal pressure is indicated by means of a permanent magnet, the position of which in the container wall can be found. This permanent magnet is fixed to an indicator bar which is itself connected to a case. This case consists of two welded bellows which expand when the pressure in the container increases and so increases the position of the permanent magnet. (DG)

Die Innendruckanzeige erfolgt mittels eines Dauermagneten, dessen Stellung durch die Behaelterwandung festgestellt werden kann. Dieser Dauermagnet ist an einem Anzeigestab befestigt, der selbst mit einem Gehaeuse in Verbindung steht. Dieses Gehaeuse besteht aus zwei zusammengeschweissten Faltenbaelgen, die bei Druckzunahme im Behaelter sich ausdehnen und somit die Stellung des Dauermagneten veraendern. (DG)Original Title

AbstractAbstract
[en] An isolator or the like for nuclear power stations employed to separate two fluids or two pressures or other sensing instruments from the containment or elsewhere includes first and second fluid filled bellows having a fluid connection in between and which together provide a pressure transfer mechanism. Excessive travel of the bellows is prevented by overrange valves, one of which closes the pathway on application of high pressure. (author)
