20090303842 | MAINSPRING - Mainspring for a mechanism driven by a motor spring, especially for a timepiece, formed from a ribbon of metallic glass material. This ribbon is monolithic and has a thickness of greater than 50 μm. | 12-10-2009 |
20110072873 | METHOD FOR SHAPING A BARREL SPRING MADE OF METALLIC GLASS - The invention relates to a method for shaping a barrel spring made of a unitary ribbon of metallic glass that comprises calculating the theoretical shape to be given to said unitary ribbon of metallic glass so that each segment, once the spring is fitted in the barrel, is subjected to the maximum bending momentum, shaping said ribbon by imparting bends thereto characteristic of said free theoretical shape in order to take into account a potential reduction of the bends once the ribbon is released, relaxing the ribbon in order to set the shape thereof by heating the same, and cooling down said ribbon. | 03-31-2011 |
20120281510 | METHOD FOR MAKING A SPRING FOR A TIMEPIECE - The invention relates to a method for making a spring for a timepiece that comprises at least one monobloc ribbon of metal glass including at least one curvature. The method is characterized in that said method comprises the step of shaping by means of plastic-deformation said monobloc ribbon in order to obtain at least a portion of said curvature. | 11-08-2012 |
