| 20080199273 | Method to limit a creep of bolts and gaskets of bolted flanged connections - A method to limit or exclude operational creep of the bolts and gaskets of Bolted Flanged Connections (BFCs) is disclosed. The method consists in the use of bolts and gaskets manufactured from the same Shape Memory Alloys (SMAs) having temperature intervals of reverse martensitic phase transformation close to operational temperatures of the BFCs. These bolts and gaskets of the BFCs are shape-memorized to the compression (bolts) and “swelling” (gaskets) during (1) the formation of stress-induced martensite under temperature of martensite state of the SMAs while bolt preload application, or (2) during the formation of stress-induced martensite while loading-unloading previously stretched bolts and previously compressed gaskets under temperature of martensite state resulting in residual bolt elongations and residual gasket contraction followed by bolt preload application. Constrained shape recovery of initial length of the bolts and initial thickness of the gaskets under operational temperatures of the BFCs is accompanying by appearance of reactive shape-recovering stresses having direction inverse to the direction of operational creep of the bolts and gaskets that limits or excludes their operational creep. | 08-21-2008 |
| 20140356094 | ASSEMBLY PROVIDING A CONNECTION THAT IS SELF TIGHTENING WITH TEMPERATURE - An assembly comprising first and second parts made of composite material held one against the other by at least one fastener system comprising a bolt having a flat head from which there extends a threaded portion, and a nut having a flat head from which there extends a shank including tapping suitable for co-operating with the threaded portion of the bolt. The head of the bolt bears against a countersink formed in the first part. The head of the nut bears against a countersink formed in the second part. The fastener system is suitable, during axial expansion of the fastener system, for causing each head to tilt towards the countersink in which it is housed. | 12-04-2014 |
| 20140369785 | ASSEMBLY PROVIDING A CONNECTION THAT IS SELF TIGHTENING WITH TEMPERATURE - The invention relates to an assembly comprising first and second parts made of composite material and held against each other by at least one fastener system comprising a rivet having a flat head from which there extends a shank having an enlarged end, and a washer co-operating with the enlarged end of the shank of the rivet, the head of the rivet bearing against a countersink formed in the first part, the washer bearing against the second part. On its face remote from its face bearing against the second part, the washer presents a portion of conical shape. The washer also has a central countersink with the enlarged end of the shank of the rivet pressing thereagainst. | 12-18-2014 |
