20130016590 | TIMEPIECE MOVEMENT COMPRISING A MODULE FITTED WITH A WHEEL SET MESHING WITH ANOTHER WHEEL SET PIVOTING IN A BASE ON WHICH THE MODULE IS MOUNTEDAANM Moulin; JulienAACI VollegesAACO CHAAGP Moulin; Julien Volleges CHAANM Villar; IvanAACI BienneAACO CHAAGP Villar; Ivan Bienne CHAANM Kaelin; LaurentAACI SonvilierAACO CHAAGP Kaelin; Laurent Sonvilier CHAANM Wyssbrod; BaptistAACI NidauAACO CHAAGP Wyssbrod; Baptist Nidau CH - Timepiece movement including a module fitted with a first wheel set meshing with a second wheel set, which pivots on a base on which the module is mounted. The movement includes a means of positioning the module formed by a cam, at least most of the periphery of which forms an Archimedes' spiral. The cam is arranged so as to allow the distance of centres between the first and second wheel sets to be adjusted, when the cam is rotated on itself about the centre of the Archimedes' spiral. The cam is preferably calibrated. The invention also concerns a method of adjusting the distance of centres between the two wheel sets using said cam to optimise the gearing efficiency of the two wheel sets. | 01-17-2013 |

20140376338 | TIMEPIECE MOVEMENT HAVING A BARREL WITH REDUCED CORE DIAMETER - A timepiece movement, including a plate and a bridge carrying a barrel including a barrel mainspring between a drum and a receiving surface of a core and a cover fixed to the drum. The spring is made of a multiphase, cobalt-nickel-chromium based alloy, having a Young's modulus of between 200 and 240 GPa and a shear modulus of between 80 and 100 GPa, and having a width to thickness ratio of between 3 and 23, and the maximum radius of the steel or stainless steel core relative to the pivot axis is less than nine times the maximum thickness of the spring. The movement further includes a mechanism limiting shake including a shim-washer independent of the core and guided by a shoulder of the core. | 12-25-2014 |
