Patent FR-2771363-A1 (FR)
Title: System for improving safety at railway level crossing.
Inventor: RICHER JEAN
IPC: B61L29/18
Filed: 1997-11-26
Abstract: The system has a retarder (1) which is retracted when the level crossing is open, and projects when the level crossing is closed. This system is controlled by the train arrival system. A fog sensor actuates a flashing light in case of fog, and an object sensor is only activated when the crossing is opened. The system uses a retractable stop indicator, (1) movable indicating panels (12, 13, 16) and winking lamps (14, 17), fog detection system  and a detector of objects on the railway track.  The indicator (1) is controlled by the train arrival system, simultaneously as the crossing barriers are operated. The movable panels (12, 13, 16) are actuated by the stop sign (1) and pivot so that they are visible to the road user, the panels are only illuminated when a train arrival is due and when the crossing is closed, the green light (53) being extinguished. The object sensor only operates when the barriers are raised. The fog sensor actuates a flashing white light (17) only in the case of fog, when the visibility is less than 25 meters.

Patent FR-2788233-A1 (FR)
Inventor: SCHWEDT JOSEPH
IPC: B21B37/48
Filed: 1999-01-11
Abstract: Regulation of the traction and/or compression in a multi-cage rolling mill working with hot metal products comprises measuring the value of the rolling couple for each cage (11, 12, 1j, 1n) traversed by the metal product (B) at the moment where this product goes on to reach the following cage and then when the cage for which the measure is effected is commuted by regulation of the couple.  The last cage reached by the product delayed by regulation of the speed and acts in so far as a pilot cage with respect to all other cages situated upstream, in order to allow this to conserve a couple equal to its reference couple by adaptation of its seed. When the measures of the reference couple have been memorized in the control system (2, 3) the regulation is obtained by exploitation of a key of the distribution of the constraints between cages. The control system using this method of regulation for a multi-cage hot rolling mill is also claimed.

Title: Myrtle extract, preparation method and use
Inventor: PUYBARET CHRISTEL
IPC: A61K36/00
Filed: 1999-09-15
Abstract: The invention concerns an extract of the aerial parts of myrtle, a method for preparing said extract and dermatological or cosmetic compositions containing said extract useful for treating psoriatic pathologies. Said original myrtle extract is characterised in that it has anti-inflammatory, antiproliferative and anti-bacterial properties capable of being advantageously used for treating psoriasis, and related disorders.
