Title: Retaining spring for sliding roof for car -  has second spring to increase spring force of first spring
Inventor: AUSPRUNG ERICH
IPC: B60J7/02
Filed: 1990-10-01
Abstract: The retaining spring (1) for the sliding roof of a motor vehicle is made from a flat metal strip and has its free end bent to a V-shape (12). The front flank (11) of this V- shape engages the sloping face (18) of the locking device (13).

As the V-shaped end is forced upwards it abuts against a second spring (15) in the form of a tongue cut out of the main spring (1). The spring force on the V-shaped end is thus increased in the region of the limit of its deflection. USE/ADVANTAGE - Sliding roof for vehicle. The spring facilitates the installation of the sliding roof.

Filed: 1991-01-31
Abstract: A tracking circuit is disclosed for a recording and/or playback machine that scans a recording medium without contact. The tracking circuit of a CD-player is provided for example with a coarse drive (M2, SP) on which is mounted a fine drive. In order to be able to guide the data-scanning light beam (L) along the data tracks of the disk (CD), the coarse drive (M2) is switched on from time to time. The coarse drive generates mechanical vibrations, however, which can cause track loss or even focus loss, if at the same time defects are found on the CD, for example scratches or fingerprints. In order to increase the scanning reliability, the track error signal (TE) or the focus error signal (FE) is checked for errors by a detector (H1), for example. As long as the detector (H1) indicates an error, the coarse drive (M2) remains switched off.

Inventor: DAENDLIKER RENE PROF
IPC: G01L1/24
Filed: 1992-01-28
Abstract: In order to obtain unique non-modulo-2 pi -independent measurement results, the fibre optic force measuring procedure, which is based on the voltage-induced birefringence of a monomode optical fibre (4), provides a compensation procedure for the phase differences, caused by the action of the force on the optical fibre (4) and the change in birefringence following therefrom, in the two linear modes of the light waves at the outlet end. According to one variant procedure, use is made as a compensation element of a liquid crystal cell whose birefringent effect is electrically controllable. The maximum of an autocorrelation function produced as an image and of the voltage value, associated therewith, at the liquid crystal cell is evaluated as a measure of the birefringence to be compensated, and consequently of the force acting. 
<??>In another basic variant procedure, the two component waves are guided by an optical component (15) having linearally spatially-dependent birefringence transverse to the direction of propagation of the wave fronts. As a result, the autocorrelation function can be obtained as a spatial coordinate and electronically recorded using a linear detector (16), for example a linear array. Under specific, defined preconditions, the location of the maximum in the autocorrelation function is a measure of the birefringence caused in the optical fibre (4) by mechanical stress, from which it is possible, in turn, to calculate the magnitude of the force acting on the force sensor (3).
