A printed wiring board includes a substrate (20) on which a wiring pattern (12) has been formed, and a fuse (6) provided on the substrate (20). One end of the fuse (6) is directly connected to a first pad (12a) of the wiring pattern (12), and the other end of the fuse (6) is directly connected to a second pad (12b) of the wiring pattern (12). The fuse (6) is covered by a protective material (7).

The pressure in a cylinder of a combustion engine is determined on the basis of vibrations in the engine which are generated during movement of the piston. A vibration signal (S) from a vibration sensor situated on a cylinder is filtered in the region about the piston top dead center position, at the transition from compression to expansion, in a special filter in which a half Hanning filter acts upon the vibration signal before and an exponential filter acts upon the vibration signal after the piston top dead center position. The filtered signal (U) is thereafter converted to a pressure signal (P) on the basis of an established relationship between vibration and pressure. The half Hanning filter has a significantly shorter time window (TH) than the exponential filter (TE). The filter cleans the vibration signal in an advantageous manner and makes more reliable pressure determination possible.

An apparatus for controlling a ribbon transport mechanism of a ribbon feed system includes a supporting structure carrying a plurality of ribbon transport devices including a ribbon storage spool, a ribbon take-up spool, and at least one ribbon guide around which roller the ribbon is passed, a ribbon feed path including the ribbon guide, between the storage and take-up spools and through an operating station where a work operation is carried out which utilises the ribbon, the ribbon transport mechanism in use, transporting the ribbon along the ribbon feed path between the storage and take-up spools, the apparatus including a mounting structure for mounting at least one of the ribbon transport devices so as to permit the respective device to move relative to the supporting structure in response to changes in ribbon tension occurring in the ribbon feed path, and a sensor device which is sensitive to such movements to provide an input which is dependant upon the extent of such spool movement, to a controller, the controller controlling operation of the transport mechanism in response.

A device for fastening facade plates, includes a threaded bar which extends from a holding element. The holding element is provided with an annular space at the first end thereof, which is located near the threaded bar. The annular space encompasses a wall that is made of an elastic material. A channel extends from the annular space to a second end which is located at a distance from the threaded bar while a valve, by means of which the channel can be sealed, is provided at the second end.
