Abstract: There is described an FM receiver (29) including; an antenna (2) able to receive a high frequency signal from a transmitter; a high frequency stage (3); an oscillator (5); a mixer unit (30) able to provide a signal (S6) at an intermediate frequency (fIF); an FM demodulation stage (8); and an automatic frequency control stage (36) able to control the oscillator, so as to keep said intermediate frequency (fIF) of said signal (S6) constant. This receiver further includes a locked loop (32) arranged to enslave said intermediate frequency (fIF) from a pilot frequency (fp) present in the demodulated signal. One advantage of such a locked loop is that the intermediate frequency is enslaved so that the aliasing phenomenon does not prevent demodulation of the signals containing the RDS data.

Abstract: The folding clasp for an interchangeable watch strap comprises at least two arms articulated together and foldable against each other, provided with a fixing device to hold the clasp in closed position. The free end of one (1) of the arms (1, 3) is provided with a securement device for the end of a strap tongue (11) comprising a guide (8) having in cross-section a general U shape, an axle (9) connecting the two lateral wings of the guide (8) and holding members (10) adapted to coact with the upper surface of the tongue (11) of the strap. The free end of the other arm (3) of the clasp is pivoted on a cover (14) with the help of a screw (12), this cover (14) having lateral portions (13) interconnected by an axle (15). The cover (14) of the clasp comprises retaining members (16) adapted to coact with the upper surface of a second tongue (17) of the strap.

Abstract: Electronic module for regulation of a watch movement with mechanical winding, comprising a generator (1) permitting converting the mechanical energy supplied by said mechanical watch movement into a measuring signal (G+; G−) and an electronic circuit (11) supplied by said generator. The electronic circuit comprises an energy dissipation circuit (9) permitting applying at least two separate braking couples more than zero to said generator (1).

Abstract: A bracelet made of links has two rows of side links forming the edges of the bracelet and at least one row of central links. The side links have each one two blind bores opening on the inner side directed towards the central links and the central links are traversed each one by two bores extending therethrough. Free pins are placed freely but without any looseness in the bores of the lateral links and of the central links and they have, at each one of their ends, a groove. The side links have, opening on their lower face, at least one recess giving access to the grooves of two adjoining pins. Blocking members are designed for being inserted into the recesses of the side links and they include retaining members co-operating with the grooves of the pins.

Abstract: The device for securing a watch strap to a watch casing comprises an intermediate element (1) to which is fixed the end of the watch strap (3), this intermediate element (1) being adapted to be received between the lugs (4) of the watch casing (2) by sliding in a complementary formation (10, 5) on the lateral surfaces of the intermediate element (1) and the internal surfaces of the lugs (4). The intermediate element (1) comprises a flap (11) pivoted about an axis (12) transverse to the watch strap and subject to a resilient action (15). This flap comprises a locking nose (16) coacting in service position with a locking surface (8) on the end surface of the watch casing (2). This nose 16 is applied by said resilient action (15) against this locking surface (8) when the intermediate element (1) is in the service position introduced between the lugs (4) of the casing (2).

Abstract: The electronic circuit allows the control or regulation of the speed of rotation of a microgenerator (1) in a watch movement. It comprises two inputs (G−, G+) connected to said microgenerator, a quartz oscillator (3, 4), an energy-dissipation circuit,(9) for braking said microgenerator, energy-dissipation control means (5, 6, 7, 30, 31) for controlling the energy dissipation of the energy-dissipation circuit as a function of the frequency difference between the signal coming from the quartz oscillator and the signal coming from said microgenerator, and a rectifier and voltage-transformer (2) for rectifying and multiplying the signal coming from said microgenerator, with at least one capacitor (C1, C2, C3) charged by said microgenerator via at least one switch (17, 18, 19). The momentary energy dissipation of the braking circuit can further be reduced when the capacitors are charged.
