Abstract: La présente invention concerne des couches de protection multiples pour objets métalliques (1), notamment des aubes de turbine à gaz. Sachant qu'il existe deux mécanismes de corrosion différents, qui conditionnent la durée de vie de tels objets, on applique deux couches protectrices superposées dont la couche intérieure (2) protège contres les attaques de la corrosion à des température comprises entre 600°C et 800°C (HTKII), et la couche extérieure (3) offre une protection optimale contre la corrosion à des températures comprises entre 800°C et 900°C (HTKI). En outre, on peut encore prévoir comme revêtement de protection extrême une couche (6) formant barrière thermique. On préfèrera comme première couche de revêtement (2) une couche de diffusion présentant une teneur en chrome supérieure à 50 % et une teneur en fer et/ou en manganèse supérieure à 10 %, et comme seconde couche de revêtement (3) une couche de MCrAlY, avec par exemple environ 30 % de chrome, environ 7 % d'aluminium et environ 0,7 % d'yttrium, qui seront appliquées par projection au plasma à pression réduite.

Abstract: Un grille-pain électrique comprend au moins un porte-pain retenu en position de grillage par un électroaimant dont l'organe de déclenchement peut être actionné manuellement ou électriquement par une commande de synchronisation qui comprend un étage de comptage commandé par rythmeur. Pour actionner cet étage de comptage, un oscillateur comprenant deux transistors programmables complémentaires combinés est raccordé du côté de l'entrée au circuit de courant de charge d'un condensateur de détermination de la fréquence et du côté de la sortie, à travers le point de division d'un diviseur de tension, à une résistance dépendante de la température agencée à l'entrée d'horloge de l'étage de comptage, qui enclenche un commutateur dans le circuit de l'électro-aimant qui coopère avec le levier de commutation. L'électroaimant coopère avec une ancre de fixation agencée à une extrémité d'un levier à cliquet à deux bras relié de manière pivotable au porte-pain et dont l'extrémité de pivotement coopère avec le levier de commutation du porte-pain.

Abstract: The specification describes method and an apparatus for separating different components of liquid mixture in a separation chamber (120). The separation is performed by admitting the liquid mixture into the separation chamber (120), the separation chamber (120) having confronting surfaces spaced more closely than the respective lengths of the confronting surfaces. An electric field is then impressed toward at least one of the confronting surfaces of the separation chamber for separating the different the liquid components according to their relative influenceability to the electric field. The separated liquid components of the same influenceability are then mechanically moved in streams each of unlike net influenceability near each other transversely to the electric field, the streams being in communication parallel to the separation influence, so as to transfer a portion of at least one of the liquid components to another of the respective streams by virtue of the continued action of the electric field as the streams progress transversely to the electric field. Finally, the separated steams are removed from the separation chamber (120). <IMAGE>

Abstract: A process for forming the ridge structure of a self-aligned semiconductor laser, particularly useful for long wavelength devices as required for signal transmission systems. 
     Described is the process as applied to an InP-system, double heterostructure (DH) laser. A thin Si₃N₄ layer (41) is inserted between the photoresist mask (42) that defines the ridge structure, and the contact layer (35). This results in improved adhesion and reduced etch undercutting whereby the ohmic contact area is increased, heat development decreased and device properties improved. Using a Si₃N₄ layer (41) deposited at a high plasma excitation frequency (RF) for adhesion promotion, and a low frequency deposited (LF) Si₃N₄ layer (43) for device embedding, provides for the etch selectivity required in the process step that is used to expose the contact layer to ohmic contact metallization deposition.

Abstract: Pour générer des images céphalométriques, par exemple en analyse orthodontique, on utilise une sonde (13) reliée à un ordinateur (1) afin de déterminer directement la position de divers points anatomiques de la tête (12) d'un patient maintenu en place par un dispositif de retenue (6). La position de la pointe de la sonde est déterminée au moyen d'émetteurs (14) et de récepteurs soniques (4). On utilise les points localisés par la sonde pour déterminer la position de points de repère anatomiques pour tracés céphalométriques, y compris, par extrapolation, la position de points inacessibles à la sonde. Ceux-ci sont alors utilisés pour produire un tracé céphalométrique qui peut être superposé sur une image vidéo de la tête du patient. On évite ainsi l'utilisation de techniques radiographiques ou invasives.

Abstract: On produit un matériau d'emballage souple usinable susceptible de former une fermeture recollable à la température ambiante en appliquant un adhésif et une fine pellicule sur un substrat tel qu'une pellicule en polyester. Etant donnée la finesse de la pellicule, elle se rompt lorsque l'on ouvre la fermeture, permettant à l'adhésif de former une interface recollable dans la région de la fermeture. Comme l'adhésif est enfermé initialement dans le matériau, celui-ci peut-être utilisé comme d'autres matériaux d'emballage par des machines de façonnage, de remplissage et de fermeture.

Dans des modes de réalisation particulièrement préférés, on utilise des résines d'acide iminodiacétique d'agarose ayant des cations de cuivre qui sont particulièrement utiles pour obtenir des compositions de protéines rsT4 stables et homogènes.

Title: Pressure sensitive adhesive laminate.
Inventor: RAGLAND G WILLIAM
IPC: C09J7/50
Filed: 1990-05-08
Abstract: This invention relates to improved polymer-pressure sensitive adhesive combinations, particularly in the form of laminates, and methods of producing same. This invention improves the bond strength of the pressure sensitive adhesive to the polymer layer by priming the polymer surface with a curable urethane primer before applying the pressure sensitive adhesive to the polymer surface. If the polymer surface is not "active" to the curable urethane primer, the polymer surface is first activated with a silicon-containing treating agent. The laminates of this invention have superior bond strength, especially longterm bond strength. Of particular interest are the embodiments of this invention wherein the polymer is a silicone foam and the pressure sensitive adhesive is either acrylic or silicone adhesive.

Abstract: Un dispositif à cylindre comporte un cylindre à courbure réglable (1) et un contre-cylindre (7) entre lesquels passe une bande sans fin de matière (8). Afin d'empêcher une pression accrue sur les bords (17) de la bande, des éléments à expansion (6) qui agissent perpendiculairement au plan de pression (E) déforment elliptiquement l'enveloppe de cylindre (3). Cela entraîne une réduction de la force de pression exercée par les éléments de support hydrauliques (5) agissant sur le plan de pression (E). Un dispositif de commande, par exemple des cloisons (25, 26) pouvant être déplacées de manière synchrone dans le sens axial au moyen de broches (29, 30), garantit que lors d'un réglage de la largeur de travail, uniquement les éléments de support nécessaires (5) et uniquement les éléments à expansion (6) situés à l'extérieur de la largeur de travail reçoivent du fluide hydraulique.

Date May 16, 1991.A process and a device for automatic determination of parameters for process control systems with unknown transfer behavior are useful for controlling special technical processes in which a functional relationship between process input and process output variables is unknown, at least in parts, while maintaining the properties of the output variables (target functions) within certain acceptable limits. To this end, measured values obtained by the process are subjected to statistical analysis from which control parameters such as theoretical value functions and weighting factors are derived automatically and incorporated in a universally applicable control specification. The control specification is used to determine the control parameter. Adaptation to different processes as well as suitability tests for various control parameters for process control can be carried out comparatively simply using predetermined calculation procedures, conversion factors or the like.
