Patent EP-0294465-A1 (EP)
Inventor: DE LA CHAPELLE MICHAEL
IPC: H01Q3/26
Filed: 1987-12-04
Abstract: Le réseau d'alimentation d'entreprise utilise des éléments opto-électroniques électroluminescents tels que des diodes laser (12) reliées ensemble en chaîne pour distribuer des signaux numériques, RF, micro-ondes, MMW et de la lumière à modulation par impulsions. Chaque diode présente deux bornes ou facettes couplées à des fibres optiques (16, 18) en vue du raccordement à un système d'antennes actif en phase par exemple. Le nombre et l'impédance des diodes sont sélectionnés de manière à fournir une bonne adaptation d'impédance à large bande à la source d'excitation RF/micro-ondes/MMW/numérique. On peut utiliser de multiples chaînes de diodes en séries branchées en parallèle pour les grands réseaux d'alimentation d'entreprise.

Abstract: In a high flux sealed neutron tube provided with a Penning type ion source (1) the magnetic field for confining the ionised gas (9) is rendered more divergent in the direction of the emission zone of the ions by action on the system of magnets (8) of the ion source. The ion beam issuing from the plasma is accelerated (2) and projected onto a target (4). The geometry and the position of the anode (13) inside the ion source adapt to the topography of the lines of force, for minimum intercept of the trajectories of the ionising electrons oscillating in the structure, an adaptation obtained in particular by the use of a truncated anode, the generatrices of which follow the lines of force.

IPC: H04J3/00
Filed: 1989-03-07
Abstract: In an integrated digital network with at least three nodes, A, B, and C, a call placed at node A to be transmitted through the network from node A to node B to node C, is compressed in multiple modes. In response to the path selected, the speech signal in node A is compressed in a first mode for transmission to node B. In node B, the speech signal is compressed in a second mode for transmission to node C, where the first and second modes involve dissimilar algorithms for compression of speech signals. At node C, the speech signal would again be adapted for supply to a receiving station. The system can accommodate as many modes of compression as desired.

Abstract: On assure le support et la protection contre l'environnement d'une photographie (10) en la montant sur une feuille acrylique transparente et sensiblement rigide (12). Une couche (11) d'environ 0,2 mm d'épaisseur de résine acrylique est appliquée sur la feuille acrylique et la face d'émulsion de la photographie est placée sur cette couche. Une seconde couche (13) de résine acrylique est appliquée au dos de l'épreuve, de façon à enfermer complètement l'épreuve entre les deux couches. Les couches acryliques ainsi appliquées sont ensuite vulcanisées. Les couches de résine peuvent être appliquées à partir de buses (30, 33) et répandues selon l'épaisseur désirée au moyen d'au moins un cylindre (20). Dans un équipement automatisé, les buses effectuent un mouvement alternatif parallèle à la feuille acrylique. On peut réaliser la même technique de montage en plaçant l'épreuve sur une feuille acrylique (48) à l'intérieur d'une enveloppe (53). L'enveloppe contient également deux goussets allongés (51), qui sont à base d'un matériau opaque aux rayons ultraviolets et qui sont montés à une extrémité de la feuille acrylique. Chaque gousset contient une résine acrylique fluide, vulcanisable à l'ultraviolet et à un seul composant, qui est comprimée depuis une ligne de rupture affaiblie (52) dans le gousset et qui est répandue sur la photographie et sous cette dernière, lorsque l'enveloppe passe à travers une paire de cylindres (50).

La face extérieure du ballonnet peut également porter une couche poreuse, spongieuse renfermant un principe actif, et au moins partiellement exprimable lors d'une pression contre la paroi vasculaire. Une telle couche peut éventuellement être prévue en plus des pores ménagés dans la paroi (6) du ballonnet. D'autre part, il existe la possibilité que le ballonnet comporte extérieurement une couche annulaire séparable, combinable avec la paroi interne vasculaire et renfermant le principe actif.
