After the ferrule has been manipulated externally of the housing to align the fibre with the component structure, the ferrule is secured in position by a UV setting adhesive. The end face of the ferrule may be adhered to the cheek of the component to maintain the alignment.

Abstract: A first mechanism (2, 5, 8, 18, 20) of the calendar drives a date indicator, bearing numbers 1 to 30, by one one-day step at the end of each day, off a rotary part (1) of an analog timepiece movement. A second mechanism (60, 62) causes the date indicator, in cooperation with the first mechanism, to move forward from the 29th to the 1st of the following month at the end of the even months. A third mechanism (75, 79, 95, 97) inhibits the action of the second mechanism at the end of the embolismic (or abundant) years whereby at the twelfth and final month of these years the date indicator displays 30 before proceeding to the 1st. The calendar is perpetual, and a date-corrector (11) and a month-corrector (54) enable the calendar to be updated.

Abstract: In a process and a device for shortening the needle thread end at the beginning of sewing and at the end of sewing in two-thread lockstitch sewing machines, the catch thread device (23) of an already existing thread-cutting device (22; 60; 90) is moved into its thread-catching position during the first stitch formation cycle, and it is ensured, either by the selection of a suitable point in time for moving the catch thread device (23) or by a compressed air flow discharged from a compressed air line (81), that at least the reserve-side leg of the needle thread loop will be caught by the catch thread device (23). Part of the needle thread end is cut off during the return movement of the catch thread device (23) into its starting position. Furthermore, the needle thread is clamped either under a leaf spring (44), or is pushed by a sufficiently large feed step under the pressure foot, and is thus held in a frictionally engaged manner.

Abstract: The movement, of the conventional type with barrel (10) and spring balance, includes two time displays with hands, the hands (3m, 3h, 3s) of one of the displays, arranged opposite one of the principal faces (1) of the movement, being driven in rotation in a known manner by a gear train comprising a toothed center wheel (12) fixed onto an arbor (13) with a pinion (11) meshing with the barrel. Opposite the other principal face (2) is found another time display, the hands (5m, 5h) of which are driven by another gear train (35, 36, 37, 38, 39, 40, 41), a toothed wheel (35) of which is fixed onto the arbor (13) of the center wheel (12). This arrangement permits reducing to a minimum the height of the other gear train and to guarantee the same small backlash for the hands of both displays. The barrel spring (10) is wound by an automatic winding arrangement comprising an oscillating mass (7) arranged opposite the other principal face (2) of the movement.
