Patent FR-2644740-A1 (FR)
Title: Cable jump-off guard for a pylon of a single-cable cableway
IPC: B61B12/06
Filed: 1989-03-22
Abstract: The hook 1 articulated at 2 is normally in a low position bearing on the stop 6 preventing the cable 7 from leaving its position in which it bears normally on the roller 8. When the fastening 9 clamped to the cable 7 approaches the hook in question, the latter actuates the lift of the hook 1 by means of the flexible and tensioned guide 11 located in the path of the fastening. The guide 11 is continuous from one of the ends to the other, at the same time passing through the orifice 16 of the hooks. The orifice of the hooks and the end fixings allow free rotation of the guide, thus making it possible, together with the cooperation of the arcuate movement of the hook and the friction of the fastening on the guide, to rotate the latter during each passage of fastening, so as to distribute the wear over its periphery. Embedded in the guide is a flexible metal ring, in which a weak monitoring current circulates. In the event of critical wear of the guide, the ring is bared, thus bringing about an earthing as a result of friction on the fastening. In the event of a break of the guide, the monitoring current is cut off.

Title: Test device for a gas-insulated metal-encased apparatus
Inventor: BOKSHORN YVES
IPC: G01R31/12
Filed: 1989-05-22
Abstract: A device for testing the quality of the insulation of a gas contained in a sealed (gastight) enclosure 12 of an installation or of a shielded apparatus, especially a medium-voltage one, includes a piezoelectric generator 24 capable of applying a voltage pulse to a spark gap in the form of a spark plug 16, placed in the enclosure 12. The correct operation of the test device is produced by comparison with the sparkover of a spark gap 34 external to the enclosure 12 and connected electrically in parallel to the internal spark gap 16. The spark gaps are calibrated in such a way that good quality of insulation is manifested by the internal spark gap 16 not sparking over, and by the external spark gap 34 sparking over, while the piezoelectric generator 24 is being actuated.

Title: Apparatus for displaying colour images on a projection screen
Inventor: EOUZAN JEAN-YVES
IPC: H04N9/31
Filed: 1989-08-01
Abstract: The invention is intended to allow subjective evaluation of the quality of a colour image. Control electronics 5 delivers to n optical valves 20-22 having their own colour characteristics, n video signals representing the same original image to be displayed on a screen 8. By virtue of operator-programmable deletion circuits, the control electronics makes it possible to perform arbitrary deletions in each of the n video signals; translation mechanisms 31, 32 make it possible to modify the relative positions of the n valves; thus the operator can modify the number and position of the colour dots of the image obtained on the screen and evaluate the effect of these modifications on the quality of the image obtained. This apparatus makes it possible to research the production of screens for colour television.
