    摘要: A drawing roller unit is constructed with a godet and an electric motor mounted on a common shaft. A passage is provided throughout the unit to convey a non-flammable scavenging gas through the motor and the godet to reduce the risk of explosion due to sparking by the electric motor and/or other electrical parts of the drawing roller. The gas introduced can leave the unit only through a narrow gap. The pressure of the gas is consequently above atmosphere pressure and prevents the entrance of air.

    摘要: The clasp wristlet is of the unfolding buckle type comprising first (4) and second (3) strips hinged to each other and comprising a catch fastening (17, 23). At one end (25) of the second strip (3) a cover (19) is mounted so as to pivot, said cover having an opening (21) in which a projecting portion (8) of said second strip is capable of being inserted. When the clasp is in a closed position, the upper face (26) of said projecting portion (8) is situated at substantially the same level as the upper face (27) of the cover (19). In this manner the thickness of the clasp is reduced. The clasp may advantageously be used for a watch wristlet.

    摘要: The assembly according to the invention comprises a hard plastic watch case (2), having on its middle part one or more sealed push buttons (5) made in an inexpensive manner. Each push button (5) comprises a hard plastic stem (10), for example the same material as the case, and an elastomer flexible head (12) which is over molded onto an external surface (15) of the case. The case and the push buttons may be manufactured by injecting two materials in a single mold. The invention applies to electronic watches and to mechanical watches.
