Abstract:
A device including a first part and at least a second part to be assembled to the first part, the first part including a body from which an attachment extends, the attachment defining a housing for the second part, for example as a timepiece hand.
Abstract:
A method of decorating an element. This method includes the following steps: taking the element (1, 11, 21, 31), the element including anchoring for improving the securing of the decoration (5) to the element; making a mask (4) of the desired thickness of the decorations (5), and having at least one opening (4′); placing the 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); filling the at least one mould with an at least partially amorphous material via hot forming; and removing the mask (4).
Abstract:
A composite material having a grainy appearance, this composite material including a metal matrix which represents, in terms of volume fraction, between 50 and 95% of the grainy composite material, the ceramic particles having a diameter that lies in the range 0.1 to 2 mm and which represent, in terms of volume fraction, between 50 and 5% of the composite material are dispersed in the metal matrix and form the remainder of this grainy composite material. A method for manufacturing a grainy synthetic material.
Abstract:
The method makes it possible to produce a decorated element for a timepiece or piece of jewellery. This decorated element may be, for example, a watch dial. The method includes the steps of taking a base substrate, and micromachining on said base substrate a mould or decorative partitions in a programmed pattern, and filling the mould or the decorative partitions with at least one filler material to obtain the decorated element. The filler material may be an epoxy resin and the mould or the partitions are obtained by melting and solidifying a solder paste or powder.
Abstract:
The invention concerns a zirconium and/or hafnium based, beryllium free, solid, amorphous alloy, with the addition of silver and/or gold and/or platinum to increase its critical diameter.
Abstract:
A method of fabricating a decoration formed of an embossed envelope the internal surface of which includes at least one attachment adapted for fixing the decoration.
Abstract:
A device including a first portion made of a first material and a second portion made of a second material, the second part extends from one of faces of the first portion and is made of an amorphous material.
Abstract:
Nickel-free bulk amorphous alloy, formed, in atomic percent, of: a zirconium and/or hafnium base, forming the balance, with a total zirconium and hafnium value greater than or equal to 52.0, and less than or equal to 62.0; copper: greater than or equal to 16.0, and less than or equal to 28.0; iron: greater than or equal to 0.5, and less than or equal to 10.0; aluminium: greater than or equal to 7.0, and less than or equal to 13.0; at least two additional metals taken from the family including Ti, V, Nb, Y, Cr, Mo, Co, Sn, Zn, P, Pd, Ag, Au, Pt, Ta, Ru, Rh, Ir, Os, and Hf when the base contains none, and Zr when the base contains none, with the cumulative atomic percentage of these additional metals being greater then 6.0 and less than or equal to 10.0.
Abstract:
The invention relates to a method for mounting at least one decorative element (3) on a support (2) comprising the steps of: a. taking a support (2) provided with at least one cavity (4); b. taking at least one decorative element (3); c. filling said cavity with a composite filler material comprising at least one metal powder and at least one organic binder and having, at the moment of filling, a viscosity comprised between 1,000 mPa·s and 1,000,000 mPa·s; d. heating the composite filler material to a higher temperature than its melting point to make it liquid; e. allowing the filler material to cool to form a substrate (6); f. making at least one housing (8) in said substrate (6); g. mounting said decorative element (3) in said housing (8). The present invention also concerns a decorative support (2) provided with at least one cavity (4) filled with said filler material forming a substrate (6) in which at least one housing (8) is formed, said housing (8) being arranged to receive said decorative element (3).
Abstract:
An oscillating winding mass (1) for a movement of a timepiece, the oscillating winding mass (1) being intended to be rotatably mounted on an axis of the movement. The winding mass includes a main element (2) and a decorative element (10), for example a logo or an acronym, a part of the winding mass (1) forming a heavy part (3) allowing the oscillation of the mass (1) in response to the movement of the timepiece and to the force of gravity, the main element (2) giving the general shape of the oscillating winding mass (1), the decorative element (10) being mechanically linked to the main element (2), the decorative element (10) being rotatably mounted on the main element (2).
