Patent number: 9310774Abstract: A method of improving the pivoting of a wheel set for a scientific instrument, including an arbor pivoting or oscillating about a wheel set axis, is provided. A static balancing of this wheel set is performed to bring the center of gravity onto this axis. A desired value is determined for the resulting unbalance moment of this wheel set about this axis, corresponding to a predetermined desired divergence between a first principal longitudinal axis of inertia of this wheel set, and this axis. This wheel set is set in rotation at a predetermined speed about this wheel set axis, and the resulting unbalance moment is measured with regard to this axis. An adjustment is made to the value of the resulting unbalance moment of this wheel set about this axis within a given determined tolerance with regard to this desired value.Type: GrantFiled: November 30, 2012Date of Patent: April 12, 2016Assignee: The Swatch Group Research and Development LtdInventors: Thierry Conus, Marco Verardo, Ivan Villar, Andres Cabezas Jurin, Jean-Luc Helfer, Emmanuel Graf

Patent number: 9304493Abstract: A timepiece escapement mechanism, including a balance having no roller and an escape wheel, between which impulses are transmitted by a flexible, single-piece mechanism, connected by at least one flexible strip to a fixed structure or to the wheel. Oscillation is maintained by a balance spring ending in a balance spring stud which is mobile during operation, and which is guided by a flexible guide member with flexible strips, and whose center of rotation is coaxial to the balance, the balance spring stud receiving a pin which is mobile in a cam path of the wheel. During the oscillations, the balance spring stud is moved relative to its locking position under action of force exerted by the balance spring, and the pin maintains and regulates the oscillation.Type: GrantFiled: March 27, 2013Date of Patent: April 5, 2016Assignee: Nivarox-FAR S.A.Inventors: Marc Stranczl, Thierry Hessler, Andres Cabezas Jurin, Davide Sarchi

Patent number: 9207640Abstract: An escape mechanism including a flexible single-piece mechanism for transmission of impulses between an impulse pin of a balance, and teeth of an escape wheel. Each tooth includes a lever with a pin that can be actuated by a lifting piece, a low level of the wheel carrying the pins on a same level as stop members of a plate, and a high level carrying the lifting pieces. The impulse pin pivots a lever opposite thereto, either to cause the pin to cooperate in abutment with the second stop member, or to move the lifting piece thereof opposite the first stop member and to cause the pin to bypass the second stop member, allowing the wheel to rotate to a next tooth.Type: GrantFiled: March 27, 2013Date of Patent: December 8, 2015Assignee: Nivarox-FAR S.A.Inventors: Marc Stranczl, Thierry Hessler, Andres Cabezas Jurin, Davide Sarchi
