Patent number: 7517138Abstract: Control device for a watch movement having a part rotatably movable around an axis A. The device is associated with a watch case (11) and has a lock (25) actuatable from outside the watch. The lock is movably mounted in translation to the periphery of the watch case (11). The device also has a movably mounted plate (30) which is rotatable around an axis D inside the watch case and is kinematically connected to the lock. An arm (34) is pivotable around and axis B, whose first end is placed on the plate in such a way that it is freely rotatable around an axis C non-merging with the axis D and whose other end is fixed to the part for driving the movement.Type: GrantFiled: September 27, 2005Date of Patent: April 14, 2009Assignee: Bruno Affolter S.A.Inventor: Alain Guyot

Patent number: 5384392Abstract: The invention is a new process to produce polyparaphenylene vinylene or polyparathienylene vinylene polymers using a sulfonium-based polyelectric precursor. This precursor is treated directly with acid to obtain the polymers required. These polymers have high molecular weights and are particularly advantageous in the plastics transformation field.Type: GrantFiled: June 17, 1992Date of Patent: January 24, 1995Assignee: Thomson-CSFInventors: Olivier Sagnes, Jean-Claude DuBois, Valerie Massardier, Tran van Hoang, Alain Guyot

Patent number: 4768616Abstract: An acoustic filter adapted to be fitted on a pipe for the purpose of absorbing pressure waves. The acoustic filter has a body constituted by a cylinder, an inlet and outlet end, a locking ring fitted in a groove located at the inlet and outlet ends, coupling means within the locking rings for coupling the filter to a pipe. A holder tube fitted with diffuser rings for connecting the coupling means. A deformable bag made from a flexible material is mounted between the inlet and outlet ends, shaped like a cylindrical sleeve and surrounds the holder tube and diffuser rings. The bag defines with an inner wall of the cylinder a chamber for receiving a pressurized gas.Type: GrantFiled: May 27, 1987Date of Patent: September 6, 1988Assignee: Commissariat a l'Energie AtomiqueInventors: Philippe Richard, Jean-Charles Papillon, Alain Guyot, Carlo Corbellini
