A method for fabricating optical components in the cladding of an optical fiber bus by the utilization of a laser. An excimer laser (601) fabricates either an optical coupler opening or an optical mode scrambler (613) by ablatively removing the cladding (506) from the optical core of an optical fiber bus (505) without damaging the optical core. Either coupler housing or a mode scrambler housing is...

Hollow bodies are mfd. by a process in which: (a) the inner walls of a die (3) forming the outer contour of the hollow body are coated with an adhesive agent; and (b) the die cavity is filled completely with plastic flakes. After cross-linking the outer flakes in contact with the adhesive, the non-cross-linked flakes are removed.

Fine cuts are produced in the tread of a tyre by placing cutters between the outer periphery of the unformed tyre and the outer radial edge of the carcass, viz. belt layer, during closing of the vulcanising mould and/or swelling of the material. When the mould is opened, the tread rubber is cut radially outward. Pref. the cutters (3) are fitted between the ribs (2) of the outer mould (1) which for...

The locking device is used to lock an axially displaced component in the required setting position. It has a rod, extending along the setting axis and a locking disc, rotated about its longitudinal axis, co-acting with a spring-loaded pin. The locking disc has a multi-sided opening (18) for receiving a rod with a corresponding multi-sided cross-section. The disc further comprises a cam projection ...

Zn-coated sheet, as used in bodywork mfr., are welded together in an arrangement in which the edge regions (3, 4) at least almost come into contact to form a pocket-shaped gap (8) along the path of a weld seam that is to be formed. The gap may be interrupted at predetermined intervals at which the parts are brought together by a spot weld.
