Abstract: A process for decorating a timepiece component, wherein it comprises the following steps: deep engraving (E10) of a surface to be decorated of the timepiece component with a femtosecond laser; and surface structuring (E20) of said surface to be decorated of the timepiece component, these two decorations being at least partially superposed on each other.

Abstract: A process for decorating a dial; wherein it comprises a step (E1) of engraving a pattern in a pad-printing cliché with a femtosecond laser, then wherein it comprises a step (E20) of transferring said pattern to the dial using the pad-printing cliché.

Abstract: Method for engraving a component (1; 3) involving application to the component of a laser beam (5) the pulses of which each last less than one picosecond, so as to machine or remove material from the component and achieve coloration of the surface (6) in the bottom of the machining

Abstract: A narrow aisle stacker crane is provided, which includes a base unit capable of traveling along aisles in a warehouse and a mast structure that is connected to the base unit. The mast structure may have a height greater than approximately 10 m. A hoisting carriage for an operator, with an attached load carrying platform, is included and is arranged to travel vertically along the mast. The base unit, the hoisting carriage and the load-carrying platform are sized to travel along warehouse aisles of 0.9 m to 1 m in width. The velocity of the base unit in a horizontal direction may be between 1 m/s to 5 m/s. The velocity of the hoisting carriage and load-carrying platform in the vertical direction may be less than 1.5 m/s. Horizontal movement of the base unit and vertical movement of the hoisting carriage and load-carrying platform may take place at the same time, so that fast item placement and retrieval can take place despite relatively low movement speeds.
