Patent FR-2467639-A1 (FR)
Title: Moving component paint applicator - has spray gun travelling obliquely to component movement to produce vertical spray strip
Inventor: GERNEZ ALAIN
IPC: B05B13/04
Filed: 1979-10-18
Abstract: The applicator coats or paints, by projection of dry or wet particles, components travelling horizontally, along vertical strip areas, and particularly vertical edges. It uses one or more spray guns, aimed at the strip to be coated, and travelling to and from along a straight path (8) inclined to the travel of the component. Movement of the gun mounting is matched to the component travel speed to produce a vertical strip on the latter, from top to bottom, or vice versa. Coating of the vertical edges can be effected prior to that of the remainder of the component.

Title: Contactless continuous pressure monitor for vehicle tyre - detects volumetric variations of bellows connected to tyre surface
Inventor: SALOU ALAIN
IPC: B60C23/04
Filed: 1980-06-30
Abstract: The device can be used for tyre pressure measurements while the associated wheel is rotating, and includes one or more pairs of bellows connected to the chamber by a manometric pipe. The pressure in the bellows is thus the same as the pressure in the chamber. The pressure variations produce volume variations of the bellows. Distance sensors are placed in front of the bellows to measure the resultant variations in the distances between them and the bellows. The device is fixed to the chamber, and the measurement direction, is parallel to the axis of rotation of the wheel. The device can be used in motor cars and aeroplanes.
