Abstract: A method of permanent assembly between at least a first part formed of a first material on the one hand, and at least a second part formed of a second material on the other hand which is configured to confine the first part in the permanent assembly.

Abstract: A shock absorber bearing for an arbour of a timepiece wheel set. The arbour includes a pivot-shank extended by a pivot. The bearing includes a support including a recess for receiving a pivot system into which the pivot-shank is inserted. The pivot system is arranged to absorb, at least in part, shocks experienced by the timepiece wheel set and is formed of a single piece made of an at least partially amorphous metal alloy.

Abstract: A method of assembling a device including first and second parts, the method including: taking the first and second parts; assembling the first and second parts provided by their arrangement so a gap is present between the first and second parts; taking a metal alloy, chosen for its ability to become at least partially amorphous; shaping the metal alloy to fill the gap between the first and second parts to join them and thereby form the device, the metal alloy having been subject to a treatment allowing the alloy to become at least partially amorphous, at a latest at a time of the shaping. The metal alloy is subject to a temperature increase above the melting temperature thereof causing the alloy to lose any local crystalline structure, the increase followed by cooling to a lower temperature than vitreous transition temperature thereof allowing the material to become at least partially amorphous.

Abstract: A method of producing a first part having at least one surface, formed of a first material. The first part includes at least one coating on the at least one surface. The production method includes: a) taking a second part including a cavity forming the negative of the first part; b) depositing the coating, including at least a first layer, onto the second part; c) taking a first metallic material, chosen for its ability to become at least partially amorphous; d) shaping the first material in the cavity of the second part so as to secure the coating to the at least one surface of the first part, the first material having been subject to a treatment allowing it to become at least partially amorphous, at the latest at the time of the shaping operation; e) separating the first part from the second part so as to obtain the first part coated with the coating.

Abstract: A special hand for abrupt acceleration. The hand is mounted to pivot around a staff so as to be able to indicate an item of information. The hand is made from an at least partially amorphous metal alloy.

Abstract: A process for adjusting a device including a first piece and at least one second piece, wherein the at least one second piece is fixed to the first piece by a joint made from a first material arranged between the first and second piece. The first material is an at least partially amorphous metal alloy. The process further includes: heating at least the joint to a heating temperature in a range of between a glass transition temperature and a crystallisation temperature of the first material; modifying a position of the at least one second piece until a desired determined position is obtained; cooling at least the joint so that it retains its at least partially amorphous state.

Abstract: A dial of a timepiece. The dial includes at least one foot. The foot is fixed on the dial and is used to fix the dial on the timepiece. The foot is produced in a metallic alloy which is at least partially amorphous.

Abstract: An escapement system that includes an anchor fitted with a fork configured to cooperate with a pin mounted on a disc and a shaft including arms configured to receive pallets to cooperate with at least one escape wheel. A part of the escapement system is made from an at least partially amorphous metal alloy.

Abstract: The present invention relates to a method of making a timepiece plate. This method is characterized in that it includes the following steps: a) taking (A1, A2) the material forming the plate including at least one metallic element; b) forming (B1, B2) the plate; c) cooling (C) everything so as to obtain the timepiece plate in an at least partially amorphous state; and d) retrieving (D) the plate.

Abstract: The present invention relates to a method of decorating an element. This method includes the following steps: a) taking the element (1, 11, 21, 31), said element including anchoring means (7) for improving the securing of the decoration (5) to said element; b) making a mask (4) of the desired thickness of the decorations (5), and having at least one opening (4?); c) placing said at least one opening in the mask (4) against the place to be decorated so as to form at least one mould (4?, 6, 6?, 6?, 100); d) filling said at least one mould with an at least partially amorphous material via hot forming; e) removing the mask (4).

Abstract: The present invention concerns a portable object (1). This portable object includes a case (2) to which a bracelet or strap (3) is fixed taking the form of two bracelet or strap strands. The portable object is characterized in that at least one of the bracelet or strap strands is moveably mounted to slide relative to the case so that the length of the bracelet or strap can be adjusted.

Abstract: The present invention concerns a decorative piece (1) including a first (2) and a second part (3). The second part (3) is secured in the first part (3) by inlay. The invention is characterized in that at least one of the parts (2, 3) is made of an at least partially amorphous material.

Abstract: The invention relates to a pressure sensor (6). This pressure sensor (6) comprises a flexible membrane (11) cooperating with a transmission device (10) that enables a value representing the pressure to be supplied on the basis of the deformation of the membrane (11). The membrane (11) is made from an at least partially amorphous material in order to optimise the dimensions of the sensor (6).
