Patent FR-2666380-A1 (FR)
Title: Boost regulator for a turbocharged (supercharged) engine
Inventor: MATHIEU SALMON
IPC: F02B37/12
Filed: 1990-08-29

Title: Device for ablating, through the transparency of a plastic film, using a laser, and applications to spraying and to marking
Inventor: MICHEL ROCHE
IPC: B23K26/18
Filed: 1990-09-19
Abstract: The invention relates to the methods making it possible to ablate, according to a pattern, through a plastic film, a layer, for example a metal layer, using a laser and, moreover, to exploit the consequent spraying of material for printing, displaying or gilding. The face (2) made of plastic is illuminated by a laser (1) pulse of very short duration and conveying sufficient energy density to cause heat-up of the layer at constant volume, which gives rise to a very intense shock-wave causing, upon reflection off the layer (3) to be ablated, the descaling and ejection of the latter, the support layer (2) remaining intact. The invention can be used both for demetallising flexible or rigid supports so as to produce capacitors, printed circuits or optical masks, and for spraying material so as to carry out printing or gilding or to produce large-area remotely-chargeable erasable display devices.

Filed: 1992-10-30
Abstract: A cell, particularly a hematopoietic cell population wherein the cells are trapped with respect to activation by an antigen to which the immune system of the host (human or animal) is to be made tolerant. The cells contain a genetic sequence of which the expression product (e.g. HSV1-TK-) may, when its production is increased so that it is present in a sufficient quantity within said trapped cells, react $i(in situ) with a pharmaceutically active substance (e.g. acyclovir) to induce the destruction of the cells and of means (e.g. a promoter of an interleukin receptor controlling the expression of said genetic sequence) which are specifically induced by an activation signal provided by the antigen to the cells, to cause the aforesaid increased production. The production of drugs implementing the above mentioned principles in order to prevent host immune system dysfunctions which are natural (autoimmune diseases) or induced (grafts), is also described.

Title: Procédé amélioré de commande automatique de gain dans un récepteur superhétérodyne de signaux radioélectriques et circuits pour la mise en Óoeuvre de ce procédé.
Inventor: PIERRE LOPEZ
IPC: H04W88/02
Filed: 1992-03-27
Abstract: Le procédé concerne l'utilisation d'une fréquence intermédiaire dans un circuit de réception et de démodulation de signaux hyperfréquence, préalablement à leur amplification. Selon l'invention, un choix astucieux de fréquence intermédiaire permet la réalisation aisée de ce circuit. La solution proposée est de choisir une fréquence intermédiaire pour le circuit de réception qui correspond à une fréquence utilisée couramment dans les téléviseurs et les magnétoscopes. Ce choix avantageux de fréquence intermédiaire permet l'utilisation d'un composant très courant et donc peu couteux, une ligne à retard vidéo, pour permettre à une boucle ouverte d'agir sur le gain de l'amplificateur avant l'application du signal à son entrée. Un système selon l'invention contient donc une ligne à retard vidéo à la fréquence intermédiaire choisie qui retardé le signal avant l'entrée d'un amplificateur dont le gain est commandé par une boucle ouverte. Application dans les télécommunications, particulièrement en AMRT.
