Patent EP-0586329-A1 (EP)
Inventor: HECK URS
IPC: C02F3/20
Filed: 1993-03-01
Abstract: The gas distributor serves for aerating water, in particular for supplying oxygen in biological waste-water (effluent) purification plants, but also for aerating inland waterways, the oxygen content of which has been decreased as a result of introduction of pollutants. The gas distributor includes a baseplate (2), over which is stretched a membrane (3) having fine orifices (16). Air, oxygen or other gases are pumped in between the baseplate (2) and the membrane (3) at a volume per unit time such that the membrane (3) slightly expands. Excessive expansion is prevented by a grating upper part, which extends over the entire membrane (3). The membrane (3) is connected to the baseplate (2) via an attachment device made of three shaped sections (6-8), which attachment device engages into an e.g. winding recess (11) having a dovetail-shaped cross-section. The membranes (3) are firmly clamped to the baseplate (2) by a quick-release fastening. The present design does not use any adhesive, which can damage the membrane (3). In addition, the completely fabricated gas distributor plates are supplied ready for service at the installation site, the mounting, exchange and maintenance being greatly simplified or accelerated in comparison to the previous designs. <IMAGE>

Abstract: Un système permettant de sculpter une cornée est utilisé en chirurgie pour reformer la cornée de l'oeil. Le système comprend un système d'apport d'une énergie laser qui est couplé à un système de positionnement de filtre et un système de topographie de la cornée. Le système de positionnement de filtre suspend un filtre de sculpture au-dessus de la surface de la cornée. Le filtre de sculpture contrôle le niveau d'enlèvement des tissus qui se produit dans chaque zone de la cornée en absorbant un certain pourcentage de l'énergie laser incidente dans diverses régions du filtre. Le système de positionnement possède également un conduit d'apport d'eau à la surface de la cornée. Une pellicule mince d'eau est chauffée par application du laser afin de créer des microexplosions qui délogent et éjectent le tissu afin de procéder à l'ablation de la cornée. Le système de topographie de la cornée fournit des informations de retour en temps réel sur la courbure de la cornée, avant, pendant et après l'opération chirurgicale.

Abstract: Un appareil ferroélectrique est réalisé à l'aide d'un électrode de fond (11) composée d'un oxyde conducteur comme le RuOx appliqué sur un substrat (10) en silicium ou en silice. Une matière ferroélectrique comme le titanate de zirconate de plomb (TZP) (13) est déposée sur l'électrode de fond, et une couche intermédiaire conductrice (12) est formée à l'interface située entre la matière ferroélectrique et l'électrode. Cette couche intermédiaire est issue de la réaction opérée entre les matières du ferroélectrique et de l'électrode. Dans ce cas précis, ce serait du Pb2RU2O7-x. Une couche supérieure conductrice (14) est déposée sur le ferroélectrique. Cette couche peut être en métal ou bien dans la même genre de matériaux que ceux qui constituent l'électrode de fond, auquel cas une autre couche intermédiaire (15) peut être formée à l'interface. Un dispositif réalisé selon ce procédé présente l'avantage de mieux résister aux effets dus à la fatigue, aux pannes et au vieillissement.

Abstract: The movement of a pair of sliding doors (2) is controlled by a drive system (9) with a control unit (11) depending on a curve that represents the door speed during the opening, closing and reversing processes. The drive system is a motor (3) with two belts (4,5). The door position sensor (8) works in conjunction with the roller (7) at the end of the horizontal belt. The curve of speed versus door position is a linear function of position cubed, position squared, position and a constant (ie four arbitrary constants in total) and there is a separate curve for opening and closing processes. A microcomputer (13) allows the algorithms to be input to the motor, the arbitrary constants being changed via a keyboard (15).

Title: Coating for biomaterial
Inventor: STEMBERGER AXEL DR
IPC: A61L33/00
Filed: 1994-10-05
Abstract: The term biomaterial is generally applied to describe a material which can be introduced into the bloodstream or the tissue of the human body, for example infusion, cardiac or balloon-tipped catheters, electrodes for pacemakers or defibrillators, suture material, vascular prostheses, supportive structures for vessels, so-called stents or the like. It is known to coat such biomaterials in order to prevent, in particular, deposition of plasma and cell constituents and hence coagulation. According to the invention, a lacquer-like coating of a blood- and tissue-compatible material having a layer thickness below 100 micrometers, preferably 10 micrometers, is built up and is permanently degraded in the body. Any depositing plasma or cell constituents are liberated upon degradation of this coating material. Moreover, anticoagulants and anti-inflammatory substances may be incorporated in the coating material.

The orbits (29, 30) along which the grippers of two consecutive carousels travel intersect each other in the zone where the flasks pass from one carousel to the other. In this zone the flask is immediately held between the opposition elements of the opposite grippers of the carousels, which open and close alternately. The opposition elements of one of the two consecutive carousels are spring-mounted. Preferably the opposition elements of the grippers of the operating carousels are immobile and the opposition elements of the grippers of the service carousels are spring-mounted. Special variable-profile cams control the transfer of the flasks between the carousels of the machine.

Abstract: A series of operations for hibernation and wake-up are executed at high speed in a system in which an address for saving the content of the main memory serves as a hibernation file managed by the OS file system. 
     When the information processing system enters hibernation mode, the system accesses an area on an external storage device where there is stored file allocation information managed by the OS file system thereby obtaining allocation information of the hibernation file. This information is input into a buffer (steps 805, 806). The system uses allocation information in the buffer to save the content of the main memory and VRAM as well as allocation information into the hibernation file (steps 808, 810 and 811). In addition, the address information at the location on the external storage device where allocation information is saved is stored in a predetermined control information area (step 813). When the system is woken up, allocation information already residing in the hibernation file is used to restore the main memory and VRAM from the hibernation file.
