Abstract: A mechanical timepiece oscillator including, between a first element and a second inertial element, more than two distinct flexible strips returning the inertial element to a rest position in an oscillation plane, wherein the projections of these strips cross each other, at a point, through which passes the axis of pivoting of the second solid inertial element, and the height to thickness aspect ratio is less than 10 for each strip.

Abstract: An isochronous pivot for a resonator including two flexible strips joining attachment points of a first and a second element, defining two strip directions, and a pivot axis, at the intersection of their projections or at their intersection, each strip having a free length between its attachment points, and an axial distance between the pivot axis and the attachment point thereof farthest from the axis, the attachment point ratio X=D/L being greater than one for each strip, the strip directions defining with the axis a first apex angle whose value in degrees includes between f1(X)=108+67/(10X−6), and f2(X)=113+67/(10X−6).

Abstract: The invention concerns a device for regulating the relative angular speed between a magnetic structure and a resonator magnetically coupled to each other and forming an oscillator which defines a magnetic escapement. The magnetic structure includes at least one annular magnetic path at least partially formed of a magnetic material of which one physical parameter is correlated to the magnetic potential energy of the oscillator, the magnetic material being arranged along the annular path so that the physical parameter varies angularly in a periodic manner. The annular path includes, in each angular period, an area of accumulation of magnetic potential energy in the oscillator, radially adjacent to an impulse area. The magnetic material, in each accumulation area, is arranged so that the physical parameter of said magnetic material gradually increases angularly or gradually decreases angularly.

Abstract: A method of improving pivoting of a wheel set for a scientific instrument, including an arbor pivoting or oscillating about an axis, in which: static balancing of the wheel set is performed to bring the center of gravity onto the axis; a desired value is determined for resulting unbalance moment of the wheel set about the axis, corresponding to a predetermined divergence between a first principal longitudinal axis of inertia of the wheel set, and the axis; at a predetermined speed about the axis, the resulting unbalance moment is measured with regard to the axis; and an adjustment of the resulting unbalance moment is made within a given determined tolerance with regard to the desired value, and performed by machining both sides of a median plane including the two secondary axes of inertia of the wheel set.
